The dispute originated in August 2024, when Stratasys filed a total of two patent lawsuits against Tuozhu in the United States, involving 10 patents in total; this is the first of the two cases to complete a jury trial. In its complaint, Stratasys alleged that multiple 3D printer models in Tuozhu’s X1, P1, and A1 series fall within the scope of its patent protection, and requested that the court award damages and issue an injunction.

The rulings involved two German patents held by Yangtze Memory Technologies, corresponding to two separate lawsuits. Specifically, patent DE202020006166U1 (Case No. 7 O 12615/25) covers technology for the stepped structure of 3D memory devices; Patent DE202021004551U1 (Case No. 7 O 12614/25) relates to a barrier layer technology for word line contacts in 3D NAND memory.

The patent at issue in this case is EP 4 213 033, titled “Video Distribution System Including Progressive Playback.” The patent was granted on May 7, 2025, and Netflix promptly filed an opposition with the EPO in February 2026.

The case number for this German lawsuit is 7 O 8870/26. Previously, the Munich court had already found Disney guilty of infringing the patent and issued an injunction against the company. The patent in question, EP 2 132 923, pertains to High Dynamic Range (HDR) video technology. This technology is used to enhance the brightness, contrast, and color reproduction of video images; features previously offered by Disney+, such as Dolby Vision, involve HDR technology.

On September 1, 2026, just two weeks after German NPE PAPST LICENSING lost its case at the Munich Regional Division of the Unified Patent Court (UPC) on August 17, it filed another patent infringement lawsuit against Chinese robotic vacuum manufacturer Roborock at the UPC’s The Hague Regional Division (Case No.: UPC-CFI-0003153/2026).

This case involves European Patent EP 3 960 072 B1, which primarily relates to a sensor insertion assembly in continuous glucose monitoring devices. Abbott contends that the GS3-R infringes this patent. The respondents, however, have raised defenses against the validity of the patent in question and the allegation of infringement, citing grounds such as insufficient disclosure, addition of subject matter, and lack of inventive step. Following a preliminary review, the Milan Regional Chamber of the UPC determined that the available evidence was insufficient to invalidate the patent in question and that the GS3-R was more likely to fall within the scope of the patent’s protection; consequently, it granted Abbott’s application for provisional measures.

On September 10, 2026, the Munich Regional Division of the Unified Patent Court (UPC) denied TCL’s request that InterDigital disclose comparable portfolio licensing agreements. The court held that it remains to be determined whether TCL is willing to accept a FRAND license, and therefore it is premature to discuss disclosure at this stage.

On September 10, 2026, Canon, Sony, Huawei, and OPPO partnered with Tulip Licensing—the parent company of Tulip Innovation—to launch a new imaging patent licensing program called “Tulip Imaging.” The program will manage a portfolio of more than 125,000 patents related to advanced digital imaging and information processing.

This batch of patents consists entirely of video standard-essential patents, covering core video coding and decoding technologies. Among them is “Method and Apparatus for Inter-Frame Prediction in a Video Processing System” (registration number US11,102,478). This patent pertains to inter-frame prediction technology in video processing systems, including core processes such as deriving control points for the current block and estimating motion vector values based on adjacent blocks.

On September 1, 2026, TCL North America (TTE Technology Inc.) filed a false advertising lawsuit against Samsung Electronics America, Inc. in the U.S. District Court for the Central District of California, alleging that Samsung repackaged its older Crystal UHD standard LED TV models—simply by changing the casing—as Mini LED models for sale, in violation of the Lanham Act and relevant California unfair competition laws.
