The Federal Circuit held that claims directed to a specific improvement in database technology — a self-referential logical table that allows all types of data to be stored in a single table structure — were directed to a concrete software improvement rather than an abstract idea, surviving Alice step one and providing an important pathway for software patent eligibility.
The Federal Circuit denied mandamus to TC Heartland, a company challenging patent venue in the District of Delaware, deferring to its own longstanding rule that domestic corporations can be sued for patent infringement wherever they are subject to personal jurisdiction — a position the Supreme Court unanimously reversed in 2017.
An en banc Federal Circuit held that a patent owner’s restricted domestic sales don’t exhaust patent rights when clearly communicated restrictions are violated, and that foreign sales never exhaust U.S. patent rights — both holdings later reversed by the Supreme Court in a landmark 2017 patent exhaustion ruling.
The Federal Circuit affirmed a jury verdict of non-infringement for Apple in a wireless patent case, holding that even mathematically equivalent signal-processing operations implemented through structurally different hardware pipelines are not equivalent under the doctrine of equivalents — the different structures matter even if the mathematical outputs are the same.
An en banc Federal Circuit held that Section 2(a) of the Lanham Act, which bars registration of ‘disparaging’ trademarks, violates the First Amendment — a landmark ruling that the Supreme Court affirmed in Matal v. Tam (2017), eliminating one of trademark law’s longest-standing restrictions on trademark content.
The Federal Circuit held that there is no universal rule requiring patent damages models to begin with the smallest saleable patent-practicing unit — but remanded CSIRO’s Wi-Fi patent damages award because the district court failed to account for the patent’s standard-essential status when setting the royalty rate, requiring a FRAND-adjusted award.
The Federal Circuit unanimously rejected a patent holder’s constitutional challenge to inter partes review, holding that IPR proceedings do not violate Article III or the Seventh Amendment because patents are public rights that may be adjudicated by an administrative agency without access to a federal court or jury — a foundational ruling for the PTAB system.
The Federal Circuit held that the ITC’s Section 337 jurisdiction covers only physical ‘articles’ and does not extend to electronic transmissions of digital data — blocking the ITC from issuing exclusion orders against competitors that infringe by transmitting digital files over the internet rather than importing physical goods.
In a 6-5 en banc decision, the Federal Circuit held that laches remains a valid defense that can bar recovery of pre-suit patent damages — splitting from the Supreme Court’s copyright ruling in Petrella v. MGM and ruling that Congress had separately codified laches as a patent defense in 35 U.S.C. § 282.
On remand from the Supreme Court, an en banc Federal Circuit expanded direct infringement liability beyond the single-actor rule, holding that an entity can be liable for another’s performance of method steps when it conditions participation or a benefit on that performance and establishes the manner or timing of the performance.
An en banc Federal Circuit held 6-4 that the ITC has jurisdiction to issue exclusion orders for imported products that become ‘articles that infringe’ through induced infringement completed after importation — resolving a key question about the ITC’s reach over method patent claims and significantly expanding the ITC’s role in policing patent infringement.
The Federal Circuit affirmed the first covered business method patent review final written decision under the AIA, holding that the PTAB correctly invalidated Versata’s pricing patent under Section 101 and that CBM eligibility determinations are reviewable on appeal — establishing the Federal Circuit’s oversight role over the new PTAB CBM program.
The Supreme Court reaffirmed the Brulotte rule that agreements requiring patent royalty payments beyond a patent’s expiration date are unenforceable as a matter of law.
An en banc Federal Circuit overruled its prior ‘strong presumption’ that claim terms without the word ‘means’ are not means-plus-function limitations, holding that terms like ‘module’ that claim a function without reciting sufficient structure are subject to Section 112’s means-plus-function rules — and typically invalidated for indefiniteness when the specification lacks corresponding structure.
The Federal Circuit held that Sequenom’s patent on detecting paternally inherited cell-free fetal DNA (cffDNA) in maternal blood for non-invasive prenatal diagnosis was patent-ineligible under § 101 — finding the claims directed to a natural phenomenon (cffDNA’s presence in maternal blood) and the detection method steps conventional and insufficient to supply an inventive concept.
The Supreme Court held 6-2 that a defendant’s good-faith belief that a patent is invalid is not a defense to induced infringement liability under § 271(b) — distinguishing between validity and infringement and holding that invalidity must be raised as a defense, not as a shield against the knowledge element of inducement.
The Federal Circuit affirmed the bulk of Apple’s massive patent verdict against Samsung — including design patent damages calculated on Samsung’s entire smartphone profits rather than just infringing components — a ruling later reversed by the Supreme Court in a landmark decision on what constitutes an ‘article of manufacture.’
The Supreme Court held that TTAB likelihood-of-confusion decisions on trademark registration can preclude relitigation of the same issue in a federal court infringement suit when the usages adjudicated are materially the same.
The Federal Circuit affirmed infringement findings in a spinal implant patent case but remanded on damages, holding that lost profits are limited to products the patentee itself sells and that convoyed sales damages require a functional relationship between the patented and unpatented products — significantly narrowing the damages available to Warsaw Orthopedic.
In the first Federal Circuit decision reviewing an inter partes review (IPR) final written decision, the court affirmed the PTAB’s use of the ‘broadest reasonable interpretation’ claim construction standard in IPR proceedings — a ruling that set the rules for thousands of subsequent patent challenges.

The Federal Circuit affirmed that document-scanning and data-recognition patents are invalid under Section 101 as directed to long-practiced abstract ideas — and notably held that Section 101 invalidity can be decided at the motion to dismiss stage, before claim construction, establishing an early-exit tool in post-Alice patent litigation.
The Federal Circuit held that Myriad’s claims to methods of comparing or analyzing BRCA gene sequences were patent-ineligible under § 101 as directed to abstract mental processes — applying the Supreme Court’s Mayo framework to diagnostic comparison claims on remand from AMP v. Myriad, while upholding claims requiring specific laboratory techniques.
The Federal Circuit held that exporting a single ‘main’ or ‘essential’ component of a patented multi-component product from the U.S. can constitute infringement under Section 271(f)(1) — a ruling the Supreme Court unanimously reversed in 2017, holding that a single component is categorically insufficient.
The Federal Circuit held that DDR Holdings’ patent on a method for retaining website visitors by displaying third-party products within the host website’s visual framework — rather than redirecting visitors to the third-party’s site — was patent-eligible under Alice because the claims addressed a problem unique to the internet and produced an unconventional technical result.
The Federal Circuit provided the most comprehensive guidance yet on how to calculate reasonable royalties for standard-essential patents (SEPs) subject to FRAND commitments, holding that damages must reflect incremental value of the invention rather than value derived from standardization, and that hold-up and royalty-stacking concerns require evidentiary support.
On its third visit to the Federal Circuit, Ultramercial’s patent on ad-supported online media distribution was finally struck down as an abstract idea — completing a legal journey that spanned four years, two Federal Circuit opinions, and two Supreme Court remands, all bookended by the Alice decision.
The Federal Circuit affirmed its two-part Seagate test for enhanced patent damages, refusing to award treble damages even where a jury found willful infringement — a holding the Supreme Court would reverse in 2016 by eliminating the objective recklessness requirement and restoring broader district court discretion.
The Federal Circuit vacated a $368 million patent verdict against Cisco and Apple in VirnetX’s network security patent case, rejecting the Nash Bargaining Solution as a royalty methodology and requiring strict apportionment to the patented features even when the smallest salable unit is the accused product itself.
The Federal Circuit applied the Supreme Court’s newly articulated Nautilus indefiniteness standard to Interval Licensing’s ‘attention manager’ patents, affirming that numerous claims were indefinite while vacating non-infringement findings on other claims based on errors in the district court’s claim construction — one of the first Federal Circuit applications of the Nautilus ‘reasonable certainty’ test.
Applying the newly minted Alice framework, the Federal Circuit unanimously invalidated buySAFE’s patent on computer-facilitated transaction guarantees, holding that using a computer to create a contractual bonding relationship is textbook abstract idea territory with no inventive concept.
The Federal Circuit affirmed a landmark $1.5 billion damages award against Marvell Technology for willful infringement of Carnegie Mellon University’s hard drive signal processing patents — one of the largest patent verdicts in history — while vacating parts of the damages calculation and remanding on the royalty base for activities occurring outside the United States.
The Federal Circuit held that a patent claiming an image device profile — a collection of color and spatial data — was patent-ineligible, finding that a data structure without physical embodiment is not patentable, and that methods consisting only of mathematical correlations are abstract ideas.
The Supreme Court held 6–3 that Aereo’s service — which captured over-the-air broadcasts using thousands of tiny antennas and streamed them to individual subscribers — performed copyrighted works publicly and infringed broadcasters’ exclusive public performance right.
The Supreme Court held unanimously that software claims directed to the abstract idea of intermediated settlement, implemented on a generic computer, are patent-ineligible under §101, and articulated the two-step Alice/Mayo framework now universally applied to §101 analysis.
The Supreme Court held that competitors may bring Lanham Act false advertising claims challenging product labels even when those labels have been approved or regulated under the Food, Drug, and Cosmetic Act.
The Supreme Court held that patent claims are indefinite and invalid if they fail to inform a skilled artisan with reasonable certainty about the scope of the invention, rejecting the Federal Circuit’s overly lenient ‘insolubly ambiguous’ standard.
The Supreme Court held 6–3 that the equitable defense of laches cannot bar a copyright infringement claim for damages filed within the Copyright Act’s three-year statute of limitations.
The Federal Circuit reversed the district court and held that Oracle’s Java API declaring code and the structure, sequence, and organization of its API packages are entitled to copyright protection — reversing the landmark ruling that APIs were not copyrightable and remanding the fair use question that the Supreme Court ultimately resolved in Google’s favor in 2021.
The Supreme Court held that §285 ‘exceptional case’ fee-shifting requires only that the case stands out from others in the substantive strength of a party’s position or the unreasonable manner of litigation, rejecting the Federal Circuit’s rigid Brooks Furniture two-prong test.
The Supreme Court held that appellate courts must review §285 exceptional case determinations for abuse of discretion — not de novo — deferring to district courts that are best positioned to evaluate litigation conduct over the life of a case.
The Federal Circuit reversed Judge Posner’s dismissal of patent damages claims and held there is no categorical rule barring injunctions for standard-essential patents — but affirmed that Motorola could not obtain an injunction on its FRAND-committed SEP because it had already committed to license on reasonable terms.
The Supreme Court held unanimously that in a licensee’s declaratory judgment action for non-infringement, the patentee bears the burden of proving infringement — the same burden as in an ordinary infringement suit.

The Federal Circuit applied de novo review to all aspects of claim construction and affirmed the invalidity of Teva’s multiple sclerosis drug patents — a ruling the Supreme Court partially reversed in 2015, holding that underlying factual findings in claim construction must be reviewed for clear error rather than de novo.
The Federal Circuit affirmed the ITC’s exclusion order against Huawei and ZTE for infringing InterDigital’s standard-essential wireless patents, while clarifying important questions about the ITC’s authority to issue exclusion orders involving FRAND-committed patents — decisions that became focal points for global SEP licensing and ITC reform debates.
The Federal Circuit held that when the PTO cancels a patent’s claims during reexamination proceedings that conclude while district court litigation is still pending on appeal, the cancellation moot the district court judgment of infringement — there is no longer a valid patent to infringe — even though the district court had already entered final judgment in the patentee’s favor.
The Federal Circuit held that a defendant’s good-faith belief that the asserted patent is invalid can negate the specific intent required for induced infringement — a ruling the Supreme Court reversed in 2015, clarifying that validity and infringement are separate inquiries and invalidity is not a defense to inducement.
The Federal Circuit initially held Ultramercial’s patent on a method of distributing copyrighted media over the internet by requiring viewers to watch an advertisement to be patent-eligible — but after Supreme Court remand in light of Alice v. CLS Bank, reversed and found the claims directed to the abstract idea of monetizing digital content through advertising, invalidating the patent.
The Supreme Court held that naturally occurring DNA segments are products of nature and not patent-eligible, but that synthetically created cDNA is patent-eligible because it does not exist in that form in nature.
