In February 2025, the Court of Justice of the European Union (CJEU) significantly expanded the reach of Europe’s Unified Patent Court (UPC) through its landmark decision in BSH Hausgeräte v. Electrolux, which confirmed in part that the UPC may decide infringement claims arising in non-UPC countries against defendants domiciled in UPC states. That August, in Dyson v. Dreame, the UPC’s Hamburg Local Division (Hamburg LD) then took BSH a step further by endorsing the concept of an “anchor defendant”—under which the UPC has jurisdiction over acts of non-UPC infringement from an entity not based in a UPC country as long as another codefendant from the same “company group” is based within the UPC. On March 6, the UPC Court of Appeal took the notable step of referring the relevant portion of that case to the CJEU—the first time the UPC has ever made such a referral. Then, on March 13, the Court of Appeal ruled in another case that the UPC lacks jurisdiction over non-UPC infringement where no related codefendants are based in the UPC (i.e., where there is no anchor defendant).

Patent Litigation Feature
|
|
A Western District of Texas jury has found five claims of a single patent infringed and not proven invalid, awarding Quartz Auto Technologies, LLC $1.05M from Lyft. Quartz has since filed a motion asking Western District of Texas Judge Alan D. Albright for a permanent injunction as to one of two accused use cases for that patent, citing a post-verdict Lyft press release as “unbelievable” because in it, Lyft is in “effect . . . celebrating the jury’s finding that Lyft violated United States patent law for six years straight as a ‘Strategic Jury Verdict’”. Quartz has also moved to amend its complaint in the case to add a patent related to the infringed one, further requesting a preliminary injunction as to that patent.

In a Western District of Texas complaint, Magma Scientific, LLC has attempted to accuse Amazon (Amazon Web Services (AWS)) (7:26-cv-00093) of infringing one of six patents that the plaintiff has received from SRI International. The body of the pleading names AWS EC2 as the accused instrumentality, but the attached claim chart is a copy of the one accompanying a complaint filed by Sandstone Innovation, LLC against Apple on the same day (purporting to map Apple Vision Pro against a different patent). The same monetization team is behind Magma and Sandstone.

In Case You Missed It

In December 2024, XiFi Networks R&D, Inc. sued Samsung in the Eastern District of Texas, targeting the provision of products that support multiple link operation over Wi-Fi 7, including smartphones, tablets, laptops and Chromebooks, TVs, and smartwatches. Samsung responded in part by filing petitions for America Invents Act (AIA) review of each of the 11 patents asserted (two by amended complaint). District Judge Rodney Gilstrap has denied a motion to stay the case to await the results of those proceedings, acknowledging XiFi’s contention “that it has already run into issues accessing documents and deposing witnesses about the 2008-2013 window in which there are open questions and issues regarding patent ownership in this case”.
