Numerous Storefronts Selling Counterfeits Targeted by Patent Owners in Q1

RPX’s latest quarterly report shows that litigation from operating company plaintiffs went up by 12% in Q1 2025, also decreasing by 11% compared to the fourth quarter.

However, these data exclude another distinct category of litigation filed by a small group of design and utility patent owners targeting copycats and counterfeiters selling products online. RPX excludes such “e-seller” cases from analyses of district court litigation because they tend to follow a different dynamic compared to what one might consider the usual patent suit. These e-seller cases sometimes name hundreds of defendant entities, many of which may be merely online storefronts or aliases for the same ultimate parent. Also, plaintiffs primarily seek injunctive relief instead of damages, and their cases often end with the e-seller defendant’s failure to answer, followed by a default judgment.

This category of litigation is shown in grey below to illustrate its magnitude. As shown by the rightmost bar, e-seller litigation in Q1 2025 accounted for 1,794 defendants added, or 67% of all litigation during the quarter—though this number remains subject to the caveat about defendants potentially having multiple online storefronts noted above.
