  • Defendant(s): Verizon Communications (also Cellco Partnership dba Verizon Wireless)

  • Case Number: 2:25-cv-00709 (This specific case number is for the voluntary dismissal without prejudice, other cases against Verizon may exist)
  • Filing Date: July 11, 2025
  • Outcome/Current Status: In a case filed July 11, 2025, in the Eastern District of Texas, Headwater Research LLC's patent infringement action against Cellco Partnership (dba Verizon Wireless) was voluntarily dismissed without prejudice on September 26, 2025. This means Headwater Research can refile the same patent claims against Verizon or other defendants in the future.
    • It should be noted that a jury verdict of $175,000,000 was awarded to Headwater Research LLC against Verizon Communications on July 24, 2025, for infringement of two of Headwater's asserted patents.

  • Filing Date: Not explicitly stated, but a jury award was made on April 25, 2025.
  • Outcome/Current Status: The Eastern District of Texas granted a joint motion to dismiss Headwater's claims against Samsung with prejudice, meaning Headwater cannot refile the same claims against Samsung on the patents involved in that specific case. Samsung's counterclaims were dismissed without prejudice. This outcome typically reflects a confidential settlement or licensing agreement. The case involved US 9,609,510, US 11,096,055, and US 11,405,429, not explicitly US9615192 in the dismissal details.
