This non-precedential decision concerns a patent dispute between Google LLC and Sonos, Inc. The United States Court of Appeals for the Federal Circuit reviewed a previous judgment from the U.S. District Court for the Northern District of California. The appeal primarily addresses the validity and enforceability of several Sonos patents related to media playback systems, specifically the "Zone Scene" patents (U.S. Patent 10,469,966 and 10,848,885) and the "Direct Control" patent (U.S. Patent 10,779,033). The court reversed parts of the district court's decision, particularly regarding the invalidity and unenforceability of the Zone Scene patents due to lack of written description and prosecution laches. However, the appeals court affirmed the district court's judgment that the Direct Control patent was invalid due to obviousness.

This judicial opinion from the United States Court of Appeals for the Federal Circuit details the ongoing litigation in the case of Gilbert P. Hyatt v. Coke Morgan Stewart, focusing on patent applications filed by Hyatt in the 1990s. The court addresses Hyatt's appeals concerning the affirmative defense of prosecution laches asserted by the United States Patent and Trademark Office (PTO), and Hyatt's cross-appeals regarding the district court's lack of Article III jurisdiction over certain claims. The court affirms the district court's judgment in favor of the PTO on the prosecution laches defense, finding that Hyatt engaged in unreasonable and unexplainable delay in prosecuting his applications. It also upholds the district court's determination that it lacked Article III jurisdiction over claims where the Board of Patent Appeals and Interferences had reversed examiner rejections, as Hyatt failed to demonstrate sufficient injury or dissatisfaction with these favorable decisions.

The opinion concerns an appeal by Erik Brunetti to the United States Court of Appeals for the Federal Circuit regarding the refusal to register the word "FUCK" as a trademark. The Trademark Trial and Appeal Board (Board) had previously affirmed the examining attorney's decision, citing that the word failed to function as a trademark because it is a widely-used, all-purpose expression that consumers would not perceive as a source identifier for goods and services. The Court of Appeals vacated and remanded the Board's decision, arguing that while the Board's factual findings regarding the word's ubiquity were sound, it failed to articulate a clear and consistent standard for determining when such "all-purpose word marks" can be registered, especially in light of other similar words and phrases that have been successfully trademarked. A dissenting opinion, however, asserts that the word's pervasive and varied use inherently prevents it from functioning as a source identifier, and that further guidance from the Board is unnecessary to reach this conclusion.

This opinion concerns an appeal before the United States Court of Appeals for the Federal Circuit in the case of Global Health Solutions LLC v. Marc Selner and was decided on August 26, 2025. The core issue revolves around a derivation proceeding under the Leahy-Smith America Invents Act of 2011 (AIA), which transitioned the U.S. patent system from "first-to-invent" to "first-inventor-to-file." Global Health Solutions (GHS) alleged that Selner, who filed his patent application first, derived his invention from GHS's founder, Bradley Burnam. The Patent Trial and Appeal Board (Board) ruled in Selner's favor, finding he had conceived the invention earlier and independently, a decision upheld by the Federal Circuit, which determined any procedural errors by the Board were harmless. The appeal also addresses GHS's arguments regarding corroboration of evidence, the burden of proof, and the necessity of reduction to practice for conception, all of which the court rejected.

This opinion concerns an appeal from the United States Court of Appeals for the Federal Circuit concerning a patent infringement case. The plaintiffs-appellees, including Laboratory Corporation of America Holdings, successfully sued defendants-appellants Qiagen Sciences, LLC, for infringing their U.S. Patent 10,017,810 and U.S. Patent 10,450,597, which relate to methods for preparing DNA samples. The jury initially awarded damages to the plaintiffs; however, the Court of Appeals reversed the lower court's decision, finding insufficient evidence to support the infringement claims for both patents. The core of the appeal centers on the interpretation of specific claim terms within the patents, particularly how "identical" and "target-specific primer" should be understood in the context of DNA sequencing preparation. The court concluded that the district court erred in denying Qiagen's motion for judgment as a matter of law, leading to a reversal of the infringement findings.

This is an opinion from the United States Court of Appeals for the Federal Circuit regarding the case of PowerBlock Holdings, Inc. v. iFit, Inc. The core issue revolves around the patent eligibility of PowerBlock's U.S. Patent No. 7,578,771, which pertains to selectorized dumbbells with automated weight adjustment. The Court of Appeals reversed the district court's decision, which had found most claims of the patent to be ineligible under 35 U.S.C. § 101 because they were deemed "abstract ideas." The appellate court concluded that the patent claims, particularly claim 1, describe a sufficiently specific mechanical invention and are therefore patent eligible, remanding the case for further proceedings.

This is an opinion from the United States Court of Appeals for the Federal Circuit, specifically addressing a patent infringement case between Mondis Technology Ltd. (and related entities) and LG Electronics Inc. (and related entities). The core of the appeal revolves around U.S. Patent No. 7,475,180, titled “Display Unit with Communication Controller and Memory for Storing Identification Number for Identifying Display Unit.” The court's decision centers on whether the patent's claims, particularly claims 14 and 15, are invalid due to a lack of adequate written description in the original patent application. Ultimately, the court reversed the lower court's judgment, finding the patent claims invalid because the original description supported identifying a specific display unit, not a "type of" display unit as later amended in the patent claims. As a result, all related issues, including infringement and damages, became moot.

This opinion concerns an appeal before the United States Court of Appeals for the Federal Circuit, concerning a patent infringement lawsuit between FMC Corporation and Sharda USA, LLC. Sharda USA is appealing a preliminary injunction that prevented it from selling its insecticide, arguing the lower court's interpretation of "composition" in FMC's patents was incorrect and thus, its ruling on patent invalidity was flawed. The appellate court vacates and remands the preliminary injunction, finding the district court erred in its claim construction by adding a "stability" requirement to "composition," which was explicitly removed from the asserted patents' specifications. This error subsequently affected the district court's analysis of anticipation and obviousness, requiring a reconsideration of whether Sharda raised substantial questions regarding the patents' validity.

This decision from the United States Court of Appeals for the Federal Circuit concerns an appeal concerning a patent infringement lawsuit between Jiaxing Super Lighting Electric Appliance Co., Ltd. (Super Lighting) and CH Lighting Technology Co., Ltd. (CH Lighting). The case revolves around three LED lighting patents, specifically U.S. Patent Nos. 10,295,125 ('125), 10,352,540 ('540), and 9,939,140 ('140). The court affirms the jury's finding that the '140 patent was infringed and not invalid, but reverses and remands for a new trial regarding the validity of the '125 and '540 patents due to the lower court's erroneous exclusion of evidence. Consequently, the damages award is vacated, necessitating a new trial on that aspect as well, with specific instructions to reconsider the reliability of the expert testimony on damages.

This opinion concerns an appeal before the United States Court of Appeals for the Federal Circuit, focusing on a trademark dispute between Sunkist Growers, Inc. and Intrastate Distributors, Inc. (IDI). Sunkist appealed a Trademark Trial and Appeal Board (Board) decision that dismissed its opposition to IDI's applications to register the KIST mark for soft drinks, arguing a likelihood of confusion with its SUNKIST marks. The Court of Appeals reversed the Board's decision, concluding that the Board's findings regarding the similarity of the marks were not supported by sufficient evidence and that the other factors weighed heavily toward a likelihood of confusion, ultimately determining that IDI's KIST marks are likely to cause confusion with the registered SUNKIST mark.
