Datasection Inc. (TSE: 3905), a Tokyo-listed AI infrastructure company, has sued Wolfpack Research, LLC and its affiliated entities and individuals in the U.S. District Court for the Eastern District of Pennsylvania. The filing, dated July 31, 2026 U.S. time, responds to a Wolfpack Research report published on October 8, 2025 that accused Datasection of illegal conduct, specifically that its GPU procurement for AI infrastructure projects violated U.S. export-control regulations.
Datasection disputes the claim. The company says it consulted outside legal counsel in both the United States and Japan before proceeding with each project and maintains it has complied with applicable law throughout. After the report ran, Datasection says it held multiple rounds of talks with Wolfpack Research but never received what it called a sincere response, which led it to conclude that litigation was necessary.
The lawsuit asks the court to order retraction of the article and to award damages for reputational harm caused by the allegations. Datasection's August 3 disclosure lists the claim amount as undetermined. The company said it will make further disclosures on the case as developments warrant.
The dispute puts a specific compliance question, whether GPU purchases for AI infrastructure work cleared U.S. export-control checks, into a U.S. courtroom rather than leaving it to sit in a research report and a rebuttal statement. Datasection's position rests on legal sign-off obtained before the projects went ahead; Wolfpack's report is the source of the contrary claim. Both sides' accounts, as disclosed by Datasection, are set out above without independent verification of either.
