The Law Offices of David A. Gerasimow

Firm Summary: The Law Offices of David A. Gerasimow, P.C.

Firm overview. The Law Offices of David A. Gerasimow, P.C. (d/b/a "Gerasimow Law") is a small IP boutique headquartered in Chicago (153 W. Ohio St., Ste. 407), with promotional materials describing coverage in "Chicago, Dallas, and beyond." Public directory data indicates a staff of roughly 1–5 attorneys, and the firm is not listed in AmLaw or Chambers rankings. It is best characterized as a focused, founder-led patent litigation and counseling shop rather than a BigLaw or regional full-service firm.

IP litigation specialty and side preference. The firm describes itself as "a focused IP litigation practice representing innovators and technology companies in the computer hardware, software, and wireless communications sectors" (IPWatchdog, May 2026). Founder David Gerasimow's background — Fish & Richardson, Blackbird Technologies (Senior Litigation Counsel), and Husch Blackwell — spans computer hardware/software, telecommunications, networking, electronics, and Hatch-Waxman pharma work. Per the tracked case data, the firm appears exclusively on the plaintiff/patent-owner side (2 plaintiff appearances, 0 defendant), consistent with the founder's history of representing patent monetization entities (e.g., his prior role on Blackbird Tech LLC v. Cloudflare, N.D. Cal. No. 17-cv-06112). No verified defendant-side appearances are in the tracked record.

Notable cases. The firm's tracked docket includes Signal, LLP v. Renesas Electronics Corporation (E.D. Tex. No. 2:26-cv-00093), a patent infringement suit in which Colin Stalter appeared pro hac vice for plaintiff Signal, LLP. David Gerasimow's second tracked appearance (lead counsel, plaintiff side) is not publicly identified by name in the available record. I could not verify any reported verdicts, Federal Circuit appeals, or settlement figures for the current firm; a single client review (Birdeye) claims Gerasimow obtained dismissal of an infringement suit against a client, but this is not independently verified.

PTAB / IPR practice. The firm maintains an active but small-scale PTAB practice: its own job posting cites work on inter partes review and other post-grant proceedings, including drafting petitions and patent owner responses, and July 2025 USPTO (PTACTS) filings show Gerasimow as lead counsel for patent owners. No public report supports a high-volume IPR filing practice; scale appears modest.

Key practitioners. David A. Gerasimow (President/Founder; USPTO Reg. No. 57,512; admitted in Illinois and Minnesota, E.D. Tex., and the Federal Circuit; J.D. Iowa 2008; B.S. Wisconsin–Madison) is the firm's lead trial attorney. Colin J. Stalter (USPTO Reg. No. 78,221) is a patent attorney at the firm who handles litigation and PTAB matters. No other partners are reliably sourced.
