United States v. Arthrex Inc. ET ALWhether the authority of Administrative
Patent Judges (APJs) to issue decisions on behalf of the Executive Branch is consistent with the Appointments Clause of the Constitution. APJs conduct adversarial proceedings for challenging the validity of an existing patent before the Patent Trial and Appeal Board (PTAB). During such proceedings, the PTAB sits in panels of at least three of its members, who are predominantly APJs. 35 U. S. C. §§6(a)
The judgment is vacated, and the case is remanded.
The Appointments Clause provides that only the President, with the advice and consent of the Senate, can appoint principal officers.
With respect to inferior officers, the Clause permits Congress to vest
appointment power “in the President alone, in the Courts of Law, or in the Heads of Departments.”

Helsinn Healthcare S. A. V. Teva Pharmaceuticals Usa, Inc., Et Al.Whether, under the AIA, an inventor’s sale of an invention to a third party who is obligated to keep the invention confidential qualifies as prior art for purposes of determining the patentability of the invention. A commercial sale to a third party who is required to keep the invention confidential may place the invention “on sale” under §102(a). The patent statute in force immediately before the AIA included an on-sale bar.

Impression Products, Inc. V. Lexmark International, Inc.This case presents two questions about the scope of the patent exhaustion doctrine: First, whether a patentee that sells an item under an express restriction on the purchaser’s right to reuse or resell the product may enforce that restriction through an infringement lawsuit. And second, whether a patentee exhausts its patent rights by selling its product outside the United States, where American patent laws do not apply."We conclude that a patentee’s decision to sell a product exhausts all of its patent rights in that item, regardless of any restrictions the patentee purports to impose or the location of the sale.
A United States patent entitles the patent holder (the “patentee”), for a period of 20 years, to “exclude others from making, using, offering for sale, or selling [its] invention throughout the United States or importing the invention into the United States.” 35 U. S. C. §154(a). Whoever engages in one of these acts “without authority” from the patentee may face liability for patent infringement. §271(a). When a patentee sells one of its products, however, the patentee can no longer control that item through the patent laws—its patent rights are said to “exhaust.” The purchaser and all subsequent owners are free to use or resell the product just like any other item of personal property, without fear of an infringement lawsuit."

Life Technologies Corp. Et Al. V. Promega Corp.This case concerns the intersection of international
supply chains and federal patent law. Section 271(f )(1) of
the Patent Act of 1952 prohibits the supply from the
United States of “all or a substantial portion” of the components of a patented invention for combination abroad. 35
U. S. C. §271(f )(1).
We hold that a single component does not
constitute a substantial portion of the components that
can give rise to liability under §271(f )(1). Because only a
single component of the patented invention at issue here
was supplied from the United States, we reverse and

Samsung Electronics Co. V. Apple Inc.This case involves the infringement of designs for smartphones. The United States Court of Appeals for the Federal Circuit identified the entire smartphone as the only permissible “article of manufacture” for the purpose of calculating §289 damages because consumers could not separately purchase components of the smartphones. The question before us is whether that reading is consistent with §289.“We hold that it is not.”
“Section 289 of the Patent Act makes it unlawful to manufacture or sell an “article of manufacture” to which a patented design or a colorable imitation thereof has been applied and makes an infringer liable tothe patent holder “to the extent of his total profit.” 35 U. S. C. §289. As relevant here, a jury found that various smartphones manufactured by petitioners (collectively, Samsung) infringed design patents owned by respondent Apple Inc. that covered a rectangular front face with rounded edges and a grid of colorful icons on a black screen. Apple was awarded $399 million in damages—Samsung’s entire profit from the sale of its infringing smartphones. The Federal Circuit affirmed the damages award, rejecting Samsung’s argument that damages should be limited because the relevant articles of manufacture were the front face or screen rather than the entire smartphone. The court reasoned that such a limit was not required because the components of Samsung’s smartphones were not sold separately to ordinary consumers and thus were not distinct articles of manufacture. Held: In the case of a multicomponent product, the relevant “article of manufacture” for arriving at a §289 damages award need not be the end product sold to the consumer but may be only a component of that product.”

Halo Electronics V. Pulse Electronics Inc.Section 284 of the Patent Act provides that, in a case of infringement, courts “may increase the damages up to three times the amount found or assessed.” 35 U. S. C. §284. In In re Seagate Technology, LLC, 497 F. 3d 1360 (2007) (en banc), the United States Court of Appeals for the Federal Circuit adopted a two-part test for determining when a district court may increase damages pursuant to §284.
The question before us is whether this test is consistent with §284.
We hold that it is not.
The Court holds that awards of enhanced damages should be reviewed for an abuse of discretion. .. But applying that standard, the Federal Circuit may take advantage of its own experience and expertise in patent law. Whether, for example, an infringer truly had “no doubts about validity” of a patent may require an assessment of the reasonableness of a defense that may be apparent from the face of that patent. See ante, at 9. And any error on such a question would be an abuse of discretion.
“Section 284 gives district courts the discretion to award enhanced damages against those guilty of patent infringement. In applying this discretion, district courts are “to be guided by [the] sound legal principles” developed over nearly two centuries of application and interpretation of the Patent Act. Martin, 546 U. S., at 139 (internal quotation marks omitted). Those principles channel the exercise of discretion, limiting the award of enhanced damages to egregious cases of misconduct beyond typical infringement. The Seagate test, in contrast, unduly confines the ability of district courts to exercise the discretion conferred on them. Because both cases before us were decided under the Seagate framework, we vacate the judgments of the Federal Circuit and remand the cases for proceedings consistent with this opinion”

Kimble V. Marvel Entertainment, LLCRespondent Marvel Entertainment’s corporate predecessor agreed to purchase petitioner Stephen Kimble’s patent for a Spider-Man toy in exchange for a lump sum plus a 3% royalty on future sales. The agreement set no end date for royalties. As the patent neared theend of its statutory 20-year term, Marvel discovered Brulotte v. Thys Co., 379 U. S. 29, in which this Court held that a patentee cannot continue to receive royalties for sales made after his patent expires. Marvel then sought a declaratory judgment in federal district court confirming that it could stop paying Kimble royalties. The district court granted relief, and the Ninth Circuit affirmed. Kimble now asks this Court to overrule Brulotte.Stare decisis requires this Court to adhere to Brulotte. A patent typically expires 20 years from its application date. At that point, the unrestricted right to make or use the article passes to the public. Brulotte applied that principle to a patent licensing agreement that provided for the payment of royalties accruing after the patent’s expiration. The Court held that the post-patent royalty provision was “unlawful per se,” because it continued “the patent monopoly beyond the [patent] period,” Contending that such alternatives are not enough, Kimble asks this Court to abandon Brulotte’s bright-line rule in favor of a case-by-case approach based on antitrust law’s “rule of reason.” The doctrine of stare decisis provides that today’s Court should stand by yesterday’s decisions. Application of that doctrine, though “not an inexorable command,” is the “preferred course.” Payne v. Tennessee, 501 U. S. 808, 828, 827. Overruling a case always requires “special justification”—over and above the belief “that the precedent was wrongly decided.” Halliburton Co. v. Erica P. John Fund, Inc., 573 U. S. In Brulotte v. Thys Co., 379 U. S. 29 (1964), this Court held that a patent holder cannot charge royalties for the use of his invention after its patent term has expired. The sole question presented here is whether we should overrule Brulotte. Adhering to principles of stare decisis, we decline to do so. Critics of the Brulotte rule must seek relief not from this Court but from Congress.

Octane Fitness V. Icon Health & FitnessWhether the Brooks Furniture framework is consistent with the statutory textWe hold that it is not.
The lower appellate court construed the attorney fees statute in a manner that was unduly rigid. Restricting the grant of reasonable attorney fees to the prevailing party in all but two exceptions would render the statute meaningless and would contradict patent litigation norms. The appellate court’s interpretation of the statute would also impermissibly encumber the district court’s discretionary power to award such fees.

Medtronic V. Boston ScientificWhether the burden of proof shifts when the patentee is a defendant in a declaratory judgment action, and the plaintiff (the potential infringer) seeks a judgment that he does not infringe the patent.We hold that, when a licensee seeks a declaratory judgment against a patentee to establish that there is no infringement, the burden of proving infringement remainswith the patentee. We reverse the Federal Circuit’s determination to the contrary.
573 U.S. 2014Alice Corp. V. CLS Bank InternationalThe patents at issue in this case disclose a computer implemented scheme for mitigating “settlement risk” (i.e., the risk that only one party to a financial transaction will pay what it owes) by using a third-party intermediary. The question presented is whether these claims are patent eligible under 35 U. S. C. §101, or are instead drawn to a patent-ineligible abstract idea.We hold that the claims at issue are drawn to the abstract idea of intermediated settlement, and that merely requiring generic computer implementation fails to transform that abstract idea into a patent-eligible invention.

FTC V. Actavis, Inc.Whether such an agreement can sometimes unreasonably diminish competition in violation of the antitrust laws. See, e.g., 15 U. S. C. §1 (Sherman Act prohibition of “restraint[s] of trade or commerce”). Cf. Palmer v. BRG of Ga., Inc., 498 U. S. 46 (1990) (per curiam) (invalidating agreement not to compete).The Eleventh Circuit erred in affirming the dismissal of the FTC’s complaint. Pp. 8–21. (a) Although the anticompetitive effects of the reverse settlement agreement might fall within the scope of the exclusionary potential of Solvay’s patent, this does not immunize the agreement from antitrust attack. For one thing, to refer simply to what the holder of a valid patent could do does not by itself answer the antitrust question. Here, the paragraph IV litigation put the patent’s validity and preclusive scope at issue, and the parties’ settlement—in which, the FTC alleges, the plaintiff agreed to pay the defendants millions to stay out of its market, even though the defendants had no monetary claim against the plaintiff—ended that litigation.

Association for Molecular Pathology V. Myriad GeneticsWhether a naturally occurring segment of deoxyribonucleic acid (DNA) is patent eligible under 35 U. S. C. §101 by virtue of its isolation from the rest of the human genome.
Whether the patent eligibility of synthetically created DNA known as complementary DNA (cDNA), which contains the same protein-coding information found in a segment of natural DNA but omits portions within the DNA segment that do not code for proteins.
We hold that a naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated, but that cDNA is patent eligible because it is not naturally occurring. The Patent Act permits patents to be issued to “whoever invents or discovers any new and useful . . . composition of matter,” §101, but “laws of nature, natural phenomena, and abstract ideas”“ ‘are basic tools of scientific and technological work’ ” that lie beyond the domain of patent protection, Mayo, supra, at ___. The rule against patents on naturally occurring things has limits, however. Patent protection strikes a delicate balance between creating “incentives that lead to creation, invention, and discovery” and “imped[ing]the flow of information that might permit, indeed spur, invention.” Id., at ___. This standard is used to determine whether Myriad’s patents claim a “new and useful . . . composition of matter,” §101, or claim naturally occurring phenomena

Bowman V. MonsantoWhether a farmer who buys patented seeds may reproduce them through planting and harvesting without thepatent holder’s permission.We hold that he may not.

Such a sale, however, does not allow the purchaser to make new copies of the patented invention.

Caraco V. NovoWhether Congress has authorized a generic company to challenge a use code’s accuracy by bringing a counterclaim against the brand manufac turer in a patent infringement suit. The relevant statute provides that a generic company “may assert a counterclaim seeking an order requiring the [brand manufac turer] to correct or delete the patent information [it] submitted . . . under [two statutory subsections] on the ground that the patent does not claim . . . an approved method of using the drug.”We hold that a generic manufacturer may employ this provision to force correction of a use code that inaccurately describes the brand’s patent as covering a particular method of using the drug in question.
The counterclaim thus enables a generic competitor toobtain a judgment directing a brand to “correct or delete” certain patent information that is blocking the FDA’sapproval of a generic product.

Mayo Collaborative Services V. Prometheus Laboratories, Inc.Whether the claimed processes have transformed these unpatentable natural laws into patent eligible applications of those laws.Section 101 of the Patent Act defines patentable subject matter. It says: “Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefore, subject to the conditions and requirements of this title. …This provision contains an important implicit exception. “Laws of nature, natural phenomena, and abstract ideas” are not patentable. Diamond v. Diehr, 450 U. S. 175, 185 (1981); see also Bilski v. Kappos, v. Chakrabarty…. thus, the Court has written that “a new mineral discovered in the earth or a new plant found in the wild is not patentable subject matter. Likewise, Einstein could not patent his celebrated law that E=mc2; nor could Newton have patented the law of gravity. Such discoveries are ‘manifestations of . . . nature, free to all men and reserved exclusively to none.’” Chakrabarty, supra. Phenomena of nature, though just discovered, mental processes, and abstract intellectual concepts are not patentable, as they are the basic tools of scientific and technological work.” Gottschalk v. Benson, 409 U. S. 63, 67 (1972). And monopolization of those tools through the grant of a patent might tend to impede innovation more than it would tend to promote it.

This Court’s precedents provide three specific exceptions to §101’s broad principles: “laws of nature, physical phenomena, and abstract ideas.” Id., at 309. While not required by the statutory text, these exceptions are consistent with the notion that a patentable process must be “new and useful.”

Microsoft V. AT&TDoes Microsoft’s liability extend to computers made in another country when loaded with Windows software copied abroad from a master disk or electronic transmission dispatched by Microsoft from the United States?Our answer is “No.”
The master disk or electronic transmission Microsoft sends from the United States is never installed on any of the foreign-made computers in question. Instead, copies made abroad are used for installation. Because Microsoft does not export from the United States the copies actually installed, it does not “supply . . . from the United States” “components” of the relevant computers, and therefore is not liable under §271(f) as currently written.

KSR V. TeleflexObviousness as applied to patent claims.
Whether a patent claiming the combination of elements of prior art is obvious.
When a work is available in one field of endeavor, design incentives and other market forces can prompt variations of it, either in the same field or a different one. If a person of ordinary skill can implement a predictable variation, §103 likely bars its patentability. For the same reason, if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill. Sakraida and Anderson’s-Black Rock are illustrative—a court must ask whether the improvement is more than the predictable use of prior art elements according to their established functions.
The Federal Circuit addressed the obviousness question in a narrow, rigid manner that is inconsistent with §103 and this Court’s precedents. KSR provided convincing evidence that mounting and available sensor on a fixed pivot point of the Asano pedal was a de-sign step well within the grasp of a person of ordinary skill in the relevant art and that the benefit of doing so would be obvious.

LabCorp V. MetaboliteWhether the patent claim is invalid on the ground that it improperly seeks to “claim a monopoly over a basic scientific relationship,” Pet. for Cert. i, namely, the relationship between homocysteine and vitamin deficiency.The relevant principle of law “[e]xclude[s] from . . .patent protection . . . laws of nature, natural phenomena, and abstract ideas.” Diamond v. Diehr, 450 U. S. 175, 185 (1981)… The principle means that Einstein could not have “patent[ed] his celebrated law that E=mc2; nor could Newton have patented the law of gravity… Neither can one patent “a novel and useful mathematical formula.. “patent law[’s] exclu[sion of] fundamental scientific (including mathematical) and technological principles,” (like copyright’s exclusion of “ideas”) is a rule of the latter variety. Thus, the Court has recognized that “[p]henomena of nature, though just discovered, mental processes, and abstract intellectual concepts are . . . the basic tools of scientific and technological work.

Ordinarily, a federal court considering whether to award permanent injunctive relief to a prevailing plaintiff applies the four-factor test historically employed by courts of equity. Petitioners eBay Inc. and, Inc., argue that this traditional test applies to disputes arising under the Patent Act. We agree and, accordingly, vacate the judgment of the Court of Appeals.

Merck KGaA V.

S. C. § 271(e)(1).It is generally an act of patent infringement to "make, use, offer to sell, or sell any patented invention . . . during the term of the patent therefor." §271(a). In 1984, Congress enacted an exemption to this general rule, see Drug Price Competition and Patent Term Restoration Act of 1984, § 202, 98 Stat. 1585, as amended, 35 U. S. C. §271(e)(1), which provides: "It shall not be an act of infringement to make, use, offer to sell, or sell within the United States or import into the United States a patented invention (other than a new animal drug or veterinary biological product (as those terms are used in the Federal Food, Drug, and Cosmetic Act and the Act of March 4, 1913) . . .) solely for uses reasonably related to the development and submission of information under a Federal law which regulates the manufacture, use, or sale of drugs . . .

Holmes Group V. VornadoWhether the Court of Appeals for the Federal Circuit has appellate jurisdiction over a case in which the complaint does not allege a claim arising under federal patent law, but the answer contains a patent-law counterclaim."Not all cases involving a patent-law claim fall within the Federal Circuit's jurisdiction. By limiting the Federal Circuit's jurisdiction to cases in which district courts would have jurisdiction under § 1338,Congress referred to a well established body of law that requires courts to consider whether a patent law claim appears on the face of the plaintiff's well-pleaded complaint. Because petitioner's complaint did not include any claim based on patent law, we vacate the judgment of the Federal Circuit and remand the case with instructions to transfer the case to the Court of Appeals for the Tenth Circuit"

Pfaff V. Wells Electronics, Inc.Whether the commercial marketing of a newly invented product may mark the beginning of the 1-year period even though the invention has not yet been reduced to practice.We conclude, therefore, that the on-sale bar applies when two conditions are satisfied before the critical date. First, the product must be the subject of a commercial offer for sale. Second, the invention must be ready for patenting. That condition may be satisfied in at least two ways: by proof of reduction to practice before the critical date; or by proof that prior to the critical date the inventor had prepared drawings or other descriptions of the invention that were sufficiently specific to enable a person skilled in the art to practice the invention.

Patent Office may be the basis of an action under 2 of the Sherman Act, 1 and therefore subject to a treble
damage claim by an injured party under 4 of the Clayton Act
Under the decisions of this Court a person sued for infringement may challenge the validity of the patent on various grounds, including fraudulent procurement..In fact, one need not await the filing of a threatened suit by the patentee; the validity of the patent may be tested under the Declaratory Judgment Act. ..A patent by its very nature is affected with a public interest. . . . [It] is an exception to the general rule against monopolies and to the right to access to a free and open market. The far-reaching social and economic consequences of a patent, therefore, give the public a paramount interest in seeing that patent monopolies spring from backgrounds free from fraud or other inequitable conduct and that such monopolies are kept within their legitimate scope."

Asgrow V. WinterboerThe Plant Variety Protection Act of 1970, 7 U. S. C. § 2321 et seq., protects owners of novel seed varieties against unauthorized sales of their seed for replanting purposes. An exemption, however, allows farmers to make some sales of protected variety seed to other farmers. This case raises the question whether there is a limit to the quantity of protected seed that a farmer can sell under this exemption.The statute as a whole—and as interpreted by the Court of Appeals—indicates that Congress intended to preserve the farmer's right to engage in so-called "brown-bag sales" of seed to neighboring farmers. Congress limited that right by the express requirement that such sales may not constitute the "primary farming occupation" of either the buyer or the seller. Moreover, § 2541(a)(3) makes it abundantly clear that the unauthorized participation in "marketing" of protected varieties is taboo. If one interprets "marketing" to refer to a subcategory of selling activities, namely, merchandising through farm cooperatives, wholesalers, retailers, or other commercial distributors, the entire statute seems to make sense.

Cardinal Chemical V. MortonWhether the affirmance by the Court of Appeals for the Federal Circuit of a finding that a patent has not been infringed is a sufficient reason for vacating a declaratory judgment holding the patent invalid.Factors in an unusual case might justify that court's refusal to reach the merits of a validity determination—a determination which it might therefore be appropriate to vacate. A finding of noninfringment alone, however, does not justify such a result. Nor does anything else in the record of this case. The two patents at issue here have been the subject of three separate lawsuits, and both parties have 103*103 urged the Federal Circuit to resolve their ongoing dispute over the issue of validity; it would be an abuse of discretion not to decide that question in this case.

The Florida Court of Appeals and the Florida Supreme Court affirmed. We therefore agree with the majority of the Florida Supreme Court that the Florida statute is preempted by the Supremacy Clause, and the judgment of that court is hereby affirmed.

Christianson V. Coltthe Court of Appeals for the Federal Circuit held that it lacked jurisdiction, and transferred the appeal to the Court of Appeals for the Seventh Circuit. The Seventh Circuit, however, raising the jurisdictional issue sua sponte, concluded that the Federal Circuit was "clearly wrong," and transferred the case back. The Federal Circuit, although concluding that the Seventh Circuit's jurisdictional decision was "clearly wrong," addressed the merits in the "interest of justice," and reversed the District Court.The Court of Appeals for the Federal Circuit would not have jurisdiction of the appeal of a final judgment in this case under 28 U.S.C. § 1295(a)(1), since the action is not one"arising under" the patent statutes for purposes of § 1338(a) (a) In order to demonstrate that a case is one "arising under" federal patent law, the plaintiff must set up some right, title, or interest under the patent laws, or at least make it appear that some right or privilege will be defeated by one construction, or sustained by the opposite construction, of those laws. Section 1338 jurisdiction extends only to those cases in which a well-pleaded complaint establishes either that federal patent law creates the cause of action or that the plaintiff's right to relief necessarily depends on resolution of a substantial question of federal patent law, in that patent law is a necessary element of one of the well-pleaded claims. A case raising a federal patent law defense does not, for that reason alone, "arise under" patent law, even if the defense is anticipated in the complaint, and even if both parties admit that the defense is the only question truly at issue in the case.
The Federal Circuit, after concluding that it lacked jurisdiction, erred in deciding to reach the merits anyway "in the interest of justice." Courts created by statute only have such jurisdiction as the statute confers. Upon concluding that it lacked jurisdiction, the Federal Circuit had authority, under 28 U.S.C. § 1631, to make a single decision --whether to dismiss the case or, "in the interest of justice," to transfer it to a court of
appeals that has jurisdiction. The rule that a court may not in any case, even in the interest of justice, extend its jurisdiction where none exists has always worked injustice in particular cases.

Dennison Manufacturing V.

the judge found that respondent's patents were invalid for obviousness.
The Court of Appeals for the Federal Circuit reversed
Petitioner contends that the Federal Circuit ignored Federal Rule of Civil Procedure 52(a) in substituting its view of factual issues for that of the District Court.
This description of the obviousness inquiry makes it clear that whether or not the ultimate question of obviousness is a question of fact subject to Rule 52(a), the subsidiary determinations of the District Court, at the least, ought to be subject to the Rule.
We grant the petition for certiorari, vacate the judgment, and remand the case to the Court of Appeals for further consideration in light of Rule 52(a).

Enforcement of the contract is not inconsistent with the purposes of the federal patent system (1) to foster and reward invention; (2) to promote disclosure of inventions, stimulate further innovation, and permit the public to practice the invention once the patent expires; and (3) to assure that ideas in the public domain remain there for the free use of the public.

Sakraida V. Ag ProThe District Court therefore held that Dairy Establishment "may be relevant to commercial success, but not to invention," because the combination "was reasonably obvious to one with ordinary skill in the art." The Court of Appeals disagreed with the District Court's conclusion on the crucial issue of obviousness.We disagree and hold that the Court of Appeals erroneously set aside the District Court's findings. "A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. The ultimate test of patent validity is one of law. But resolution of the obviousness issue necessarily entails several basic factual inquiries, "Under 103, the scope and content of the prior art are to be determined; differences between the prior art and the claims at issue are to be ascertained; and the level of ordinary skill in the pertinent art resolved."

State trade secret law not preempted by patent law. We hold that Ohio's law of trade secrets is not preempted by the patent lawsof the United States, and, accordingly, we reverse. Trade secret may consist of any formula, pattern, device or compilation of information which is used in one's business, and which gives him an opportunity to obtain an advantage over competitors who do not know or use it. It may be a formula for a chemical compound, a process of manufacturing, treating or preserving materials, a pattern for a machine or other device, or a list of customers.' The subject of a trade secret must be secret, and must not be of public knowledge or of a general knowledge in the trade or business.

Since respondent Brunette is an alien corporation, it cannot rely on 1400 (b) as a shield against suit in the District of Oregon. The judgment of the Court of Appeals is Affirmed.

Deepsouth V. LaitramIs Deepsouth, barred from the American market by Laitram's patents, also foreclosed by the patent laws from exporting its deveiners, in less than fully assembled form, for use abroad?We disagree with the Court of Appeals for the Fifth Circuit. Under the common law the inventor had no right to exclude others from making and using his invention. If Laitram has a right to suppress Deepsouth's export trade it must be derived from its patent grant, and thus from the patent statue. We find that 35 U. S. C. § 271, the provision of the patent laws on which Laitram relies, does not support its claim.

Zenith Radio Corp. V. Hazeltine Research, Inc. (Zenith II)Whether it is consistent with the controlling limitations statute, 15 U. S. C. § 15b, to permit Zenith to recover all of the damages it suffered during the years 1959-1963 even though some undetermined portion of those damages was the proximate result of conduct occurring more than four years prior to the filing of the counterclaim."HRI contends, and the Court of Appeals held, that the statute permits the recovery only of those damages caused by overt acts committed during the four-year period. We do not agree. We therefore hold that Zenith, although suing HRI, which was named neither as a party nor as a coconspirator in the Government suit, is not barred from obtaining the benefits of the tolling statute, since it is undisputed that the conspiracy in which HRI participated was at least in part the same conspiracy as was the object of the Government's suit. From this it follows that the only issue still remaining upon HRI's limitations claim is whether Zenith can recover in its 1963 suit for damages suffered after June 1, 1959, as the consequence of pre-1954 conspiratorial conduct.."

Walker Process V. Food Mach. & Chem.Whether the maintenance and enforcement of a patent obtained by fraud on the Patent Office may be the basis of an action under § 2 of the Sherman Act, and therefore subject to a treble damage claim by an injured party under § 4 of the Clayton Act. The trial court dismissed its suit not because Walker failed to allege the relevant market, the dominance of the patented device therein, and the injurious consequences to Walker of the patent's enforcement, but rather on the ground that the United States alone may "annul or set aside" a patent for fraud in procurement. The trial court has not analyzed any economic data. Indeed, no such proof has yet been offered because of the disposition below. In view of these considerations, as well as the novelty of the claim asserted and the paucity of guidelines available in the decided cases, this deficiency cannot be deemed crucial. Fairness requires that on remand Walker have the opportunity to make its § 2 claims more specific, to prove the alleged fraud, and to establish the necessary elements of the asserted § 2 violation.

Wilbur-Ellis Co. et al. V.

S. C. § 154, the article.We are asked in substance to treat the case as if petitioners had a license for use of the machines on "1-pound" cans only. But the sales here were outright, without restriction. Adams v.

There in a discussion of a like problem we held that "the inference of an agreement in violation of the Sherman Act" is not "merely limited to particular fact complexes,"It is well settled that beyond the limited monopoly which is granted, the arrangements by which the patent is utilized are subject to the general law," United States v. Masonite Corp., supra, at 277, and it "is equally well settled that the possession of a valid patent or patents does not give the patentee any exemption from the provisions of the Sherman Act beyond the limits of the patent monopoly. By aggregating patents in one control, the holder of the patents cannot escape the prohibitions of the Sherman Act. That Act imposes strict limitations on the concerted activities in which patent owners may lawfully engage and those limitations have been exceeded in this case.

Aro Mfg. Co. V. Convertible Top Replacement Co. (Aro IThe doctrine of repair and reconstructionIn order to call the monopoly, conferred by the patent grant, into play for a second time, it must, indeed, be a second creation of the patented entity, as, for example, in Cotton-Tie Co. v. Simmons, supra. Mere replacement of individual unpatented parts, one at a time, whether of the same part repeatedly or different parts successively, is no more than the lawful right of the owner to repair his property. Measured by this test, the replacement of the fabric involved in this case must be characterized as permissible "repair," not "reconstruction

Fourco Glass Co. V. Transmirra Products Corp.Whether 28 U. S. C. § 1400 (b) is the sole and exclusive provision governing venue in patent infringement actions, or whether that section is supplemented by 28 U. S. C. § 1391 (c)We hold that 28 U. S. C. § 1400 (b) is the sole and exclusive provision controlling venue in patent infringement actions, and that it is not to be supplemented by the provisions of 28 U. S. C. § 1391 (c). The judgment of the Court of Appeals must therefore be reversed and the cause remanded for that court to pass upon the District Court's ruling that there had been no showing of acts of infringement in the district of suit.

U.S. Gypsum V. National GypsumAppellant sued appellees for the use of its patents during that period. It asserted three alternative grounds for recovery: (a) the royalty provisions of the old licensing agreements, (b) the reasonable value of the use of its patents, and (c) damages for patent infringement.By virtue of its reservation of jurisdiction in its antitrust decree to make such "directions" and "modifications" as may be appropriate to the "carrying out" and "enforcement" of that decree, the District Court had jurisdiction to grant relief. Pp.352 U. S. 463-464.
2. The enjoining of appellant's suits for royalties under the outlawed licensing agreements was proper, and, upon remand, the District Court, by appropriate modification of its decree in the antitrust case or otherwise, may require appellant to dismiss those claims. Pp. 352 U. S. 464-465, 352 U. S. 476.
3. The enjoining of appellant's suits for compensation on a quantum meruit basis and for damages for patent infringement was not justified upon the record.

Sanford v. Kepner the duty of district courts to consider and adjudicate questions of invention and patentability when parties urge them This Court has said, "It necessarily follows that no adjudication can be made in favor of the applicant, unless the alleged invention for which a patent is sought is a patentable invention." Hill v. Wooster, 132 U.S. 693, 698. The principle of the Hill case is that
the court must decide whether claims show patentable inventions before authorizing the Commissioner to issue a patent. No part of its holding or wording nor of that in Hoover Co. v. Coe, 325 U.S. 79 , requires us to say R. S. 4915 compels a district court to adjudicate patentability at the instance of one whose claim is found to be groundless. Sanford's claim was found to be groundless.

The judgment below is
Affirmed. It was always within the power of the trial judge to establish the royalty rates, and, in voting as he did, he did just that.

But examining the conduct of the plaintiff, it found no such obstacle to the maintenance of an action for infringement on that part of the patent which was valid. The Court of Appeals affirmed, and we accept the conclusion of the two courts below on this branch of the case.

Reading a list and selecting a known compound to meet known requirements is no more ingenious than selecting the last piece to put into the last opening in a jig-saw puzzle. It is not invention.

(2) The stipulations for maintenance of prices derived no support from the patent, and must stand on the same footing under the Sherman Act as like stipulations with respect to unpatented commodities.

It took the ground that respondent was making use of the patent to restrain the sale of salt tablets in competition with its own sale of unpatented tablets, by requiring licensees to use with the patented machines only tablets sold by respondent.

The article, in the language of the court, passes without the limit of the monopoly. That is to say, the patentee or his assignee having in the act of sale received all the royalty or consideration which he claims for the use of his invention in that particular machine or instrument, it is open to the use of the purchaser without further restriction on account of the monopoly of the patentees

Where a patent, though using old elements, gives the entire value to the combination, the patentee is entitled to recover from an infringer all the profits. Where profits are made by using an article patented as an entirety, the infringer is liable for all the profits unless he can show, and the burden is on him, that the profits are partly the result of some other things used by him. Where the patent admittedly creates only a part of the profits, the patentee is only entitled to that part, and he must apportion the infringer's profits and show by reliable and satisfactory evidence either what part of the profits are attributable to his patent or that the entire value of the infringing article is attributable to his patent.

Henry V. A.B.

The unlimited right of exclusive use which is possessed by and guaranteed to the patentee will be granted if the sale be unconditional. But if the right of use be confined by specific restriction, the use not permitted is necessarily reserved to the patentee. If that reserved control of use of the machine be violated, the patent is thereby invaded. This right to sever ownership and use is deducible from the nature of a patent monopoly and is recognized in the cases.

Leeds and Catlin Co. V.

S. Comp. Stat. 1901, p. 3382), the letters patent in suit were limited to expire at the same time with said foreign patents and each of them'the statute manifestly assumes that the patent previously granted in a foreign country is one granted for a definite term; and its meaning is that the United States patent shall be so limited as to expire at the same time with such term of the foreign patent.' And it is further said that the duration of the United States patent is not 'limited by any lapsing or forfeiture of any portion of the term of such foreign patent by means of the operation of a condition subsequent, according to the foreign patent.' From these views it follows that there was no abuse of discretion in granting the preliminary injunction, and the decree is affirmed.

Mast, Foos & Co.V. Stover Mfg. Co.Comity and Prior ArtsComity is not a rule of law, but one of practice, convenience and expediency. It is something more than mere courtesy, which implies only deference to the opinion of others, since it has a substantial value in securing uniformity of decision, and discouraging repeated litigation of the same question. But its obligation is not imperative. If it were, the indiscreet action of one court might become a precedent, increasing in weight with each successive adjudication, until the whole country was tied down to an unsound principle. Comity persuades; but it does not command. It declares not how a case shall be decided, but how it may with propriety be decided. It recognizes the fact that the primary duty of every court is to dispose of cases according to the law and the facts; in a word, to decide them right. In doing so, the judge is bound to determine them according to his own convictions. If he be clear in those convictions, he should follow them. ……… in determining the question of invention, we must presume the patentee was fully informed of everything which preceded him, whether such were the actual fact or not. There is no doubt the patent laws sometimes fail to do justice to an individual who may, with the light he had before him, have exhibited inventive talent of a high order, and yet be denied a patent by reason of antecedent devices which actually existed, but not to his knowledge, and are only revealed after a careful search in the Patent Office. But the statute (sec. 4886) is inexorable. It denies the patent, if the device were known or used by others in this country before his invention.

The use of any two of these parts only, or of two combined with a third which is substantially different, in form or in the manner of its arrangement and connection with the others, is, therefore, not the thing patented. It is not the same combination if it substantially differs from it in any of its parts.

Egbert V. LippmannWhether the defense that the patented invention had, with the consent of the inventor, been publicly used for more than two years prior to his application for the original letters is sustained by the testimony in the record.According to the testimony of the complainant, the invention was completed and put into use in 1855. The inventor slept on his rights for eleven years. Letters patent were not applied for till March, 1866. In the meantime, the invention had found its way into general and almost universal use. A great part of the record is taken up with the testimony of the manufacturers and venders of corset steels showing that before he applied for letters, the principle of his device was almost universally used in the manufacture of corset steels. It is fair to presume that, having learned from this general use that there was some value in his invention, he attempted to resume, by his application, what by his acts he had clearly dedicated to the public."An abandonment of an invention to the public may be evinced by the conduct of the inventor at any time, even within the two years named in the law.

Cochrane V. DeenerPatentability A process may be patentable irrespective of the particular form of the instrumentalities used. If one of the steps of a process be that a certain substance is to be reduced to a powder, it may not be at all material what instrument or machinery is used to effect that object, whether a hammer, a pestle and mortar, or a mill. Either may be pointed out, but if the patent is not confined to that particular tool or machine, the use of the other would be an infringement, the general process being the same. ... A process is a mode of treatment of certain materials to produce a given result. It is not an act or series of acts, performed upon the subject matter to be transformed and reduced to a different state or thing. If new and useful, it is just as patentable as a piece of machinery. In the language of the patent law, it is an art.

Winans v. DenmeadOn such a trial, two questions arise. The first is, what is the thing patented; the second, has that thing been constructed, used, or sold by the defendants. The first is a question of law, to be determined by the court, construing the letters-patent, and the description of the invention and specification of claim annexed to them. The second is a question of fact, to be submitted to a must be so near to a true circle as substantially to embody the patentee's mode of operation, and thereby attain the same kind of result as was reached by his invention. It is not necessary that the defendant's cars should employ the plaintiff's invention to as good advantage as he employed it, or that the result should be precisely the same in degree. It must be the same in kind, and effected by the employment of his mode of operation in substance. Whether in point of fact the defendant's cars did copy the plaintiff's invention in the sense above explained is a question for the jury, and the court below erred in not leaving that question to them upon the evidence in the case, which tended to prove the affirmative.

Gayler V. WilderPatent rights The inventor of a new and useful improvement certainly has no exclusive right to it, until he obtains a patent. This right is created by the patent, and no suit can be maintained by the inventor against any one for using it before the patent is issued.
For there was no existing and living knowledge of this improvement, or of its former use, at the time he made the discovery. And whatever benefit any individual may derive from it in the safety of his papers, he owes entirely to the genius and exertions.

Pennock V. DialogueVoluntary abandonment, or negligence, or unreasonable delay in obtaining letters patent, to destroy the right of the patentee'We are clearly of opinion that if an inventor makes his discovery public, looks on and permits others freely to use it, without objection or assertion of claim to the invention, of which the public might take notice; he abandons the inchoate right to the exclusive use of the invention, to which a patent would have entitled him, had it been applied for before such use. ….It is possible that the inventor may not have intended to give the benefit of his discovery to the public; and may have supposed that by giving permission to a particular individual to construct for others the thing patented, he could not be presumed to have done so. But it is not a question of intention, which is involved in the principle which we have laid down; but of legal inference, resulting from the conduct of the inventor, and affecting the interests of the public. It is for the jury to say, whether the evidence brings this case within the principle which has been stated. If it does, the court is of opinion that the plaintiffs are not entitled to a verdict.'

Evans V. EatonWhether, under the general patent law, improvements on different machines can be comprehended in the same patent so as to give a right to the exclusive use of several machines separately as well as a right to the exclusive use of those machines in combination.A patent may be for a new and useful art, but it must be practical, it must be applicable and referable to something by which it may be proved to be useful; a mere abstract principle cannot be appropriated by patent. The discovery must not only be useful, but new; it must not have been known or used before in any part of the world.
