The Verdict & Legal Analysis
Outcome
The case closed via Stipulated Motion for Dismissal (Dkt. No. 45), accepted and acknowledged by the Court on June 10, 2025. Plaintiff Factor2’s claims were DISMISSED WITH PREJUDICE, meaning Factor2 cannot reassert these specific infringement claims against Comerica on the same patents. Defendant Comerica’s counterclaims were DISMISSED WITHOUT PREJUDICE, preserving Comerica’s right to revive invalidity or other counterclaims in future proceedings. No damages award or trial verdict emerged.
Key Legal Issues
The Court did not issue findings on infringement, validity, or claim construction — consistent with a negotiated resolution rather than adjudicated outcome. The asymmetric dismissal terms — plaintiff’s claims with prejudice, counterclaims without — is a negotiated outcome that provides finality for Comerica on Factor2’s specific claims while retaining theoretical counterclaim leverage.

✅ Key Takeaways
For Patent Attorneys & Litigators
Stipulated dismissals with asymmetric prejudice terms are standard PAE settlement architecture — analyze carefully before characterizing as win or loss.
Search related case law →EDTX remains the dominant PAE venue; no Markman order means the patents remain judicially uninterpreted, impacting future defense strategy.
Explore precedents →For R&D Leaders & Product Teams
Authentication patent risk in banking technology is active and multi-patent — FTO reviews must cover continuation families, not just issued patents.
