Untitled case

This patent infringement litigation, case number 1:25-cv-00872, is currently active in the U.S. District Court for the District of Delaware. The plaintiffs are Voxer, Inc. and Voxer IP LLC, and the defendants are Amazon.com, Inc., Amazon Web Services, Inc., and Twitch Interactive, Inc.. Voxer, Inc. is a company known for its "walkie-talkie" messaging application, which provides live voice, text, photo, and video communication capabilities. Voxer IP LLC appears to be an entity related to Voxer, Inc. for the purpose of patent assertion. The defendants, Amazon.com, Inc., Amazon Web Services, Inc., and Twitch Interactive, Inc., are major operating companies involved in e-commerce, cloud computing services, and live streaming, respectively. The case was filed on July 14, 2025, and is assigned to Judge Gregory B. Williams.

The litigation centers on U.S. Patent No. 11,658,929. While a detailed technical sketch is not explicitly provided in the immediate search results, given Voxer's business in live communication technology and the defendants' operations, the patent likely pertains to aspects of real-time communication, data transmission, or streaming services that are alleged to be incorporated into Amazon's, AWS's, or Twitch's offerings. The procedural posture indicates that a scheduling order was issued on January 8, 2026, with a Markman hearing set for April 8, 2027, and a five-day jury trial scheduled for November 27, 2028. The District of Delaware is a popular venue for patent cases due to its specialized patent rules and experienced judiciary.

This case is notable due to the involvement of major technology companies like Amazon, AWS, and Twitch, and the potential implications for widely used communication and streaming technologies. Such disputes can highlight emerging areas of patent assertion and may result in significant financial stakes given the scale of the defendants' operations. The ongoing nature of the scheduling suggests a typical trajectory for complex patent litigation in the district, where claim construction and other pre-trial matters are meticulously planned.

Uncertainty Regarding Patent 11658929 in Case 1:25-cv-00872

While the case 1:25-cv-00872, titled Voxer, Inc. et al v. Amazon.com, Inc. et al, is confirmed as a patent infringement suit filed in the U.S. District Court for the District of Delaware, the specific patent 11658929 has not been explicitly identified as being at issue in the available search results. Docket information indicates that the plaintiff, Voxer, Inc. and Voxer IP LLC, has asserted "five patents, broadly directed to video communications over a network" against the defendants, including US10142270B2 and four other patents not individually specified in the accessible summaries. This suggests that patent 11658929 may not be among the patents asserted in this particular case.
