Untitled case

This patent infringement litigation, Case No. 4:25-cv-00576, is currently in litigation in the Eastern District of Texas.

However, public records for Case No. 4:25-cv-00576 in the Eastern District of Texas consistently identify the parties as Intellectual Ventures I LLC, et al., as plaintiffs, and American Airlines, Inc., as the defendant. This publicly available information indicates that the case was filed on May 30, 2025, and is assigned to Judge Amos L. Mazzant III. Despite the prompt specifying patent 10103845 as at issue, extensive public database searches, including on Google Patents and the USPTO's Patent Public Search, did not yield a readily identifiable U.S. patent with the number 10103845, nor was this patent linked to the Intellectual Ventures v. American Airlines case. Therefore, a specific one-line technical sketch of patent 10103845 cannot be provided, and the specific accused product or technology related to patent 10103845 cannot be identified within the context of this specific case number based on verifiable public information.

The Eastern District of Texas is a prominent venue for patent infringement litigation, often favored by patent plaintiffs, including non-practicing entities (NPEs), due to its historically efficient dockets and experience with complex patent cases. While patent filings in the EDTX saw a decline after the 2017 TC Heartland Supreme Court decision, the district has experienced a resurgence in recent years, cementing its status as a top patent litigation forum. Judge Amos L. Mazzant III, who is assigned to this case, is an experienced patent judge in the EDTX, known for handling significant patent disputes and applying evolving standards for damages, such as in cases involving willful infringement. The notability of litigation in this district often stems from its high volume of cases, the potential for substantial jury verdicts, and the strategic advantages it may offer to plaintiffs.

It appears there is some difficulty in directly identifying the key legal developments for case 4:25-cv-00576 in the Texas Eastern District Court solely based on the provided case number and patent 10,103,845. Direct searches for this specific case number did not immediately yield a clear docket with parties and detailed events.

However, a search for parallel PTAB proceedings revealed information about U.S. Patent No. 11,932,441 ('441 patent), which was subject to concurrent inter partes review (IPR) and post-grant review (PGR) petitions filed by MPL Brands NV, Inc. ("MPL") against BuzzBallz, LLC. This proceeding occurred in anticipation of a dispute over whether the America Invents Act (AIA) would apply to the patent. The Patent Trial and Appeal Board (PTAB) determined that the AIA applies to the '441 patent and subsequently denied institution of the IPR petition while granting institution of the PGR petition. This development regarding patent 11,932,441 is noted, as patent numbers can sometimes be misstated or related in a patent family, but currently, no direct PTAB proceedings have been identified for patent 10,103,845 itself.

Due to the lack of specific docket details for 4:25-cv-00576, including the parties involved, it is not possible to provide a chronological list of filing and initial pleadings, pre-trial motions, claim construction outcomes, discovery milestones, trial events, or the final disposition of this particular district court litigation at this time. Further information regarding the plaintiff and defendant in case 4:25-cv-00576 would be necessary to conduct more targeted searches for its specific legal developments.

Based on available information for case 4:25-cv-00576 in the Texas Eastern District Court, the plaintiff is Intellectual Ventures I LLC and Intellectual Ventures II LLC. The case is a patent infringement lawsuit against American Airlines, Inc..

However, despite extensive searching, there is no indication that patent 10103845 is at issue in this specific case. Intellectual Ventures is known for its broad patent assertion activities involving numerous patents, but this particular patent number was not found in direct association with case 4:25-cv-00576 in the search results.

The identified counsel of record representing the plaintiff(s) is:

• Jonathan K. Waldrop
  • Role: Lead Counsel
  • Firm: Kasowitz Benson Torres LLP
  • Office Location: San Francisco, California

While it is common practice for out-of-state firms to engage local counsel in the Eastern District of Texas, specific local counsel for Intellectual Ventures in this particular case, 4:25-cv-00576, could not be definitively identified from the public search results.
