On September 18, 2026, NEC Corporation filed another patent infringement lawsuit against Anker Innovation in the U.S. District Court for the Eastern District of Texas, alleging that security products under Anker Innovation’s eufy brand infringe on six of its U.S. patents. This marks the second patent lawsuit NEC has filed against Anker Innovation in the same court within two years (Case No.: 2:26-cv-00847).

This lawsuit cites a total of six U.S. patents, with patent numbers 12,423,985, 10,223,619, 12,641,315, 10,706,336, 10,552,713, and 11,144,776, covering technologies in the fields of video surveillance, image processing, machine learning-based video recognition, image analysis, and mobile surveillance. The products named in the complaint encompass the Eufy brand’s security hardware and software ecosystem, including smart cameras, the HomeBase security hub, video doorbells, smart locks, as well as the accompanying security app, servers, and BionicMind AI service.

It is worth noting that the filing of this new case closely follows the trial date of the previous case. The prior lawsuit filed by NEC on September 3, 2024 (Case No.: 2:24-cv-00720) was originally scheduled to go to trial on September 11, 2026; the new case was filed just one week before that trial date. In the previous case, Anker had invoked Section 101 of the U.S. Patent Act to argue that certain claims constituted abstract concepts, seeking to dismiss the allegations regarding four of the patents. In June 2026, Judge Rodney Gilstrap rejected this motion, and the court subsequently granted NEC’s request to submit a supplemental expert report on infringement regarding Patent No. 11,537,814. In other words, Anker’s procedural defenses in the previous case were all unsuccessful, and NEC filed a new case just as the previous one was entering the trial phase.

According to a complaint previously filed by Anker in the U.S. District Court for the Eastern District of Virginia, NEC sent a letter to Anker’s legal department on June 3, 2024, proposing a patent licensing offer and alleging that Anker’s products infringed on 80 of its U.S. patents. After licensing negotiations failed, NEC filed the first lawsuit three months later; the 12 patents asserted in both cases combined represent only a small fraction of those listed in the letter.

The litigation pressure Anker currently faces does not end there. This case marks the seventh patent lawsuit Anker has faced in the U.S. this year, with Anker named as the defendant in six of them. On August 26 of this year, the NPE IOT Innovations filed a lawsuit against Anker in the U.S. District Court for the Eastern District of Texas, alleging infringement of six patents (Case No.: 2:26-cv-00758); in Europe, LG Electronics and Philips have also filed lawsuits against Anker at the Unified Patent Court (UPC) regarding standard-essential patents for the Qi wireless charging standard.

As of now, Anker has not issued a public response. Whether there will be any procedural overlap between the new and existing cases, and how Anker will respond to NEC’s series of lawsuits, remains to be seen. IP Finance will continue to monitor developments.
