Broader Litigation Context
It's important to note that Fractus, S.A. has been involved in numerous patent litigations concerning its antenna technology. A significant earlier case, filed in 2009, involved ten major cell phone manufacturers, including Samsung, LG, and others. This extensive litigation campaign has resulted in both court-awarded damages and numerous settlement agreements. For instance, in a case against Samsung, a final judgment awarded Fractus over $41 million, which included damages for willful infringement. More recently, in 2024, Fractus initiated lawsuits against Geotab and Verizon, also in the Eastern District of Texas, related to different patents but within the same technology area. These cases highlight the company's consistent and vigorous enforcement of its intellectual property rights.
