The Federal Circuit held that Dealertrack’s claims covering a computer-aided system for routing automobile dealer credit applications to lenders were directed to the unpatentable abstract idea of processing credit applications — striking down the patents under § 101 because adding ‘apply it on a computer’ was insufficient to make an abstract process patent-eligible.
The Supreme Court held 6–2 that Congress acted within its Copyright Clause power when it restored copyright protection to millions of foreign works that had fallen into the public domain in the United States, and that doing so did not violate the First Amendment.
The Federal Circuit reversed a finding of indefiniteness in a touchscreen patent dispute, holding that a claim term need not be expressed in traditional means-plus-function form to invoke § 112(f) — and clarified when functional claim language triggers the algorithm-disclosure requirement, with significant implications for computer and touch interface patent litigation.
The Federal Circuit reversed a district court dismissal and held that Ultramercial’s patent on distributing copyrighted content free-to-consumers in exchange for viewing advertisements was patent-eligible subject matter under § 101 — finding the multi-step process involved meaningful, non-abstract practical implementation steps, not merely an abstract idea.
The Federal Circuit held that Classen Immunotherapies’ method claims for identifying optimal vaccination schedules to reduce chronic immune-mediated disorders were patent-eligible under § 101 in part — distinguishing between claims that merely require correlating a natural relationship and claims that require further steps of implementing a vaccination schedule based on that correlation.
The Federal Circuit held that CyberSource’s patent on a method of detecting credit card fraud by tracking internet addresses was directed to an unpatentable mental process — a gathering and comparing of information that a human could perform in their mind — and that reciting a Beauregard computer-readable medium claim did not change the analysis.
The Federal Circuit held that Myriad Genetics’ patents on isolated BRCA1 and BRCA2 gene sequences — mutations of which indicate elevated breast and ovarian cancer risk — were patent-eligible, while cDNA molecules and method claims for ‘comparing’ or ‘analyzing’ sequences were not — a major ruling later partially reversed by the Supreme Court in 2013.
The Supreme Court held that the Bayh-Dole Act does not automatically transfer title to federally funded inventions to universities; a researcher’s prior contractual assignment to a private company defeated Stanford’s patent claim.
The Supreme Court held that induced patent infringement requires knowledge of the patent, and that the willful blindness doctrine — deliberately avoiding confirmation of a high-probability fact — satisfies that knowledge requirement.
The Federal Circuit sitting en banc overhauled the doctrine of inequitable conduct, holding that rendering a patent unenforceable requires both but-for materiality (the undisclosed information would have blocked the patent) and specific intent to deceive the USPTO — dramatically narrowing a defense that had become a routine litigation tactic.
The Federal Circuit addressed joint infringement in a healthcare IT patent dispute, holding that when patients and healthcare providers together perform steps of a patented method for online patient-provider communications, neither party alone is a direct infringer — applying the direction-or-control standard for divided infringement to electronic health record systems.
The Federal Circuit ruled that the widely used ’25 percent rule of thumb’ for calculating starting-point patent royalties is inadmissible as a matter of law, vacating a $388 million damages award against Microsoft and requiring that every patent royalty calculation be tied to the specific facts of the case.
The Federal Circuit upheld Prometheus’s patents on methods for optimizing thiopurine drug dosing based on metabolite blood levels, holding the claims directed to patent-eligible subject matter because they applied natural correlations through a physical transformation — a ruling the Supreme Court unanimously reversed in 2012.
The Federal Circuit upheld patents on digital image halftoning technology as patent-eligible subject matter, holding that mathematical algorithms applied to specific, practical technological problems are not so abstract as to be excluded from § 101, and cautioning against an overly rigid application of the abstract idea exception.
The Federal Circuit reversed a summary judgment of obviousness in a deepwater drilling rig patent dispute, holding that the district court failed to give adequate weight to powerful objective evidence of non-obviousness — including commercial success, long-felt need, and failure of others — and remanded for proper analysis of the full record.
The Federal Circuit applied claim differentiation and rejected a narrowing construction of defibrillator patent claims, holding that independent claims cannot be read to require limitations found only in dependent claims — and affirmed the district court’s infringement finding on the broader interpretation.
The Federal Circuit held AstraZeneca’s patents on a once-daily budesonide inhaler formulation (Pulmicort Respules) valid and infringed in a Hatch-Waxman challenge, affirming the district court’s analysis of the complex obviousness record and reinforcing the significance of FDA-required labeling disclosures in constructive notice and § 101 analysis for pharmaceutical patents.
The Supreme Court held that the machine-or-transformation test is a useful but not exclusive test for patent eligibility under §101, and affirmed rejection of Bilski’s risk-hedging claims as unpatentable abstract ideas.
The Federal Circuit affirmed an ITC exclusion order barring importation of GPS chip products that infringed Broadcom’s GPS patents, holding that the claimed methods were patent-eligible under the machine-or-transformation test and rejecting a divided-infringement defense based on user interaction.
The Second Circuit held that eBay was not liable for contributory trademark infringement arising from third-party sellers listing counterfeit Tiffany jewelry, because eBay’s general knowledge that counterfeit goods were present on its platform — without specific knowledge of particular infringing listings — was insufficient to establish contributory infringement liability.
The Federal Circuit sitting en banc held that 35 U.S.C. § 112 contains a written description requirement that is distinct from the enablement requirement, and invalidated a broad genus patent covering all substances that inhibit NF-κB activity because the patent described the goal but not the means.
The Federal Circuit affirmed a $200 million jury verdict and permanent injunction against Microsoft for infringing i4i’s patent on a method for editing custom XML in word processing documents, rejecting Microsoft’s invalidity defense premised on a prior-sold product and upholding the clear-and-convincing evidence standard for patent invalidity claims.
The Supreme Court unanimously held that the Copyright Act’s registration requirement is a claim-processing rule, not a jurisdictional prerequisite — meaning courts can hear copyright cases even when registration has not occurred, if neither party objects.
The Federal Circuit vacated a patent damages award and held that a reasonable royalty calculation must rely on licenses that are technologically and economically comparable to the patent at issue — rejecting a royalty rate derived from re-bundling agreements that had no connection to the claimed invention.
The Federal Circuit affirmed summary judgment of invalidity of a patent on a method for bulk email delivery, holding the claims obvious under post-KSR standards where the claimed process involved only routine, predictable steps well within the common sense of a person with ordinary skill in email marketing.
The Federal Circuit upheld Prometheus Laboratories’ patents on methods of optimizing thiopurine drug dosage by measuring metabolite levels in patients, finding the diagnostic methods patent-eligible under § 101 because the claimed steps transformed an article — a patient’s blood — by detecting specific metabolite concentrations.
The Federal Circuit largely affirmed that Roche’s pegylated erythropoietin product Mircera infringed four of Amgen’s EPO patents, but vacated the district court’s double-patenting rulings and remanded for additional analysis — a significant ruling in the long-running battle over the blockbuster anemia-treatment drug market.
The Federal Circuit vacated a $1.5 billion patent damages award against Microsoft, holding that the jury’s royalty base improperly relied on the entire market value of Microsoft’s products — including features unrelated to the patented invention — without proof that the patented feature drove demand for the whole product.
The Federal Circuit en banc held that the traditional four-factor preliminary injunction test applies in Hatch-Waxman patent cases — eliminating the prior practice under which a showing of validity and infringement created a presumption of irreparable harm — and remanded the preliminary injunction against generic clarithromycin for reconsideration under the corrected standard.
The Federal Circuit addressed the joint infringement problem in method patent claims — holding that when multiple parties each perform different steps of a claimed method, infringement requires that one party direct or control the actions of the other parties performing the remaining steps, setting an important standard for software and service patents with distributed functionality.
The Federal Circuit held that a patent application claiming an isolated DNA sequence encoding the NAIL protein receptor was obvious under KSR — where the prior art disclosed both the protein and routine methods of cloning its encoding gene — marking an important application of KSR’s flexible obviousness standard to biotechnology patent claims for genetic sequences.
The Federal Circuit struck down a controversial USPTO rule that would have limited patent applicants’ right to file continuation applications claiming priority to parent patents, holding the rule was inconsistent with 35 U.S.C. § 120 — while upholding other procedural rules in the contested rulemaking package.
The Federal Circuit affirmed the validity of Sanofi’s Plavix (clopidogrel) patent, holding that prior disclosure of a racemic mixture does not anticipate a claim to an isolated single enantiomer — particularly when the enantiomer exhibits unexpectedly superior properties not predictable from the racemate.
The Ninth Circuit held that the copyright first sale doctrine does not apply to foreign-made goods, allowing Omega to prevent Costco from reselling Omega watches in the United States without authorization — a ruling the Supreme Court affirmed by an equally divided 4-4 court in 2010, leaving the Ninth Circuit’s gray-market-unfriendly rule in place.
The Federal Circuit sitting en banc held that the machine-or-transformation test is the definitive standard for determining whether a claimed process is patent-eligible under 35 U.S.C. § 101, rejecting a patent application on a business method for hedging commodity-trading risk.
The Federal Circuit held that the ITC’s limited exclusion order authority under Section 337 does not extend to downstream products of non-parties to the investigation — rejecting the ITC’s longstanding practice of excluding finished goods containing infringing components made by respondents, and limiting such broad relief to general exclusion orders.
The Federal Circuit sitting en banc eliminated the two-part ‘point of novelty’ test for design patent infringement and replaced it with a unified ordinary observer test — holding that design patent infringement is determined by whether an ordinary observer, familiar with the prior art, would find the accused design substantially similar to the patented design.
The Federal Circuit held that violation of an open-source software license condition — not merely a contractual covenant — constitutes copyright infringement, giving open-source licensors the full array of copyright remedies (including injunctions and statutory damages) rather than only contract damages when licensees violate the terms of free and open source licenses.
The Federal Circuit held that direct infringement of a method claim divided across multiple parties requires that a single defendant direct or control the performance of every claimed step — a ruling that made it significantly harder to prove infringement of internet-era method patents implemented through multi-party systems.
The Supreme Court held that the doctrine of patent exhaustion applies to method patents and that an authorized sale of a product that substantially embodies a patented method exhausts the patent holder’s rights — foreclosing downstream infringement suits against purchasers.
The Federal Circuit vacated a $78.9 million willful infringement verdict against DirecTV’s satellite broadcasting system, reversing on claim construction and holding that means-plus-function claims for software functions require more than a bare reference to software — the specification must disclose the specific algorithm performing each claimed function.
The Federal Circuit affirmed the invalidation of Aristocrat’s slot machine patent, holding that computer-implemented means-plus-function claims are indefinite under § 112 unless the specification discloses the specific algorithm that transforms a general-purpose computer into the claimed special-purpose device.
The Federal Circuit tightened the standards for inequitable conduct findings, requiring clear and convincing evidence of both materiality and intent to deceive before a patent may be rendered unenforceable — while also confirming that a patent examiner’s independent knowledge of withheld prior art does not excuse the patentee’s duty of disclosure.
The Federal Circuit addressed the interplay of written description and priority, holding that a claim amendment during prosecution that introduces new limitations must find support in the originally filed specification to maintain the benefit of the earlier filing date — a key ruling for patent drafters managing continuation and CIP application strategies.
The Federal Circuit sitting en banc abandoned its 24-year-old willful infringement standard, adopting a new two-part objective/subjective recklessness test that raised the bar for enhanced patent damages and eliminated the automatic duty to obtain opinion-of-counsel letters.
The Federal Circuit reaffirmed that prosecution history estoppel bars application of the doctrine of equivalents when a claim was narrowed during prosecution to distinguish prior art — a landmark application of Festo’s flexible bar to a complex software patent dispute.
The Federal Circuit affirmed the validity of Forest Laboratories’ escitalopram (Lexapro) patent, holding the single-enantiomer antidepressant non-obvious over the known racemic citalopram — with the critical role played by unexpected superior pharmacological properties of the isolated (+)-enantiomer over the racemate as evidence of non-obviousness.
In one of the first major post-KSR Federal Circuit obviousness decisions, the court upheld the non-obviousness of Takeda’s pioglitazone (Actos) patent, applying the Supreme Court’s flexible obviousness framework while affirming that selection from a genus of prior art compounds requires specific motivation to choose the patented compound.
The Ninth Circuit held that Google’s display of thumbnail-size images in search results is fair use, while also addressing the server test for direct infringement — holding that a website that inline-links to content stored on another server does not ‘display’ that content and thus does not directly infringe the reproduction right.
In one of the first post-KSR Federal Circuit obviousness decisions, the court invalidated Leapfrog’s patent on an electronic phonics learning toy as obvious, holding that it would have been obvious to combine the mechanical toy’s learning concept with electronic text-to-speech technology that was well-known in the prior art — a straightforward application of KSR’s flexible approach.
