Stamoulis & Weinblatt LLC: Patent Litigation Summary

Firm Overview: Stamoulis & Weinblatt LLC is a specialized intellectual property and corporate litigation boutique headquartered in Wilmington, Delaware. The firm was founded by Stamatios Stamoulis and Richard C. Weinblatt, both of whom previously practiced at major international law firms, including Fish & Richardson and O'Melveny & Myers. While the firm is not ranked in AmLaw or Chambers, industry reports identify it as a highly active and prominent player in patent litigation, particularly recognized for its high volume of cases filed in the District of Delaware. All of the firm's attorneys are registered to practice before the U.S. Patent and Trademark Office.

IP Litigation Specialty & Side Preference: The firm has a strong and clear preference for representing plaintiffs in patent infringement litigation. A 2020 Lex Machina report cited by Law360 identified the firm as the most active for plaintiffs in U.S. district courts over the preceding decade, having filed 2,074 cases. The firm's website confirms that it "often represents plaintiffs, both practicing and non-practicing entities," establishing its role as a go-to counsel for patent assertion. Its litigation experience covers a diverse range of technologies, including software, computer hardware, electronics, telecommunications, and consumer products. The firm also has a practice representing both brand and generic pharmaceutical companies in ANDA (Hatch-Waxman) litigation.

Notable Cases & Key Partners: The firm’s key partners are its founders, Stamatios Stamoulis and Richard C. Weinblatt. Both have been individually recognized as "IP Stars" by Managing Intellectual Property and as "Super Lawyers." The partners are consistently listed among the most active patent litigators in the country by case volume. A notable public result for the firm includes Richard Weinblatt's successful argument before the U.S. Court of Appeals for the Federal Circuit in Visual Memory, LLC v. NVIDIA Corp., which resulted in the reversal of a district court's dismissal under 35 U.S.C. § 101. The firm has also appeared in numerous cases on behalf of patent licensors such as Inventor Holdings, LLC and Blackbird Technologies.

PTAB / IPR Practice: While all the firm's attorneys are registered to practice before the USPTO, public records and the firm's own marketing materials do not indicate a significant focus on inter partes review (IPR) or other Patent Trial and Appeal Board (PTAB) proceedings. The firm's primary focus is on district court and appellate litigation. No reliable data on the firm's volume of PTAB appearances as either petitioner or patent owner is available.
