Plaintiff
6 cases as plaintiff.
Authentixx LLC is a patent assertion entity that does not appear to have any products or business operations. Corporate filings indicate it was formed in Delaware, while a Florida registration shows a principal address in Freeport, Florida, established in July 2023. There is no evidence of employees or revenue. An unrelated women's athletic apparel brand also uses the "Authentixx" name, but its website states it is transitioning to new ownership and does not appear connected to the litigating entity.
The company's sole activity is patent litigation. Since February 2023, Authentixx has sued nearly 50 companies in what patent intelligence firm RPX Corporation describes as its only litigation campaign. The campaign asserts a single patent generally related to a system and method for authenticating electronic content, like webpages, to prevent phishing.
As the case data shows, Authentixx is exclusively a plaintiff, a typical posture for a non-practicing entity (NPE). The company has filed its lawsuits in plaintiff-friendly jurisdictions, including the Eastern and Western Districts of Texas.
The three most recently tracked cases, filed on April 22, 2026, against Wix Com Ltd, Parler Technologies Inc, and Udemy Inc, are part of this ongoing campaign targeting companies over the use of authentication services on their websites. The campaign has targeted a wide array of defendants across various industries.
