What Sughrue Mion PLLC does
Sughrue Mion PLLC is a Washington, D.C.-headquartered intellectual property law firm founded in 1957 that has maintained an exclusive focus on IP law for 68 years. It operates two office locations (Washington, D.C. and Tokyo) and serves large multinational corporations — particularly Japanese, Korean, Chinese, Taiwanese, Indian, and European enterprises — across patent prosecution, patent and trademark litigation, PTAB post-grant proceedings, and trademark portfolio management. The firm has obtained more U.S. patents than any other law firm globally and has ranked #1 or #2 in annual USPTO utility patent grants for 30 consecutive years, with 4,957 patents obtained for clients in 2025 and over 3,000 patents granted annually since 2000.
The firm is organized around three core practice areas: Litigation (federal courts, U.S. International Trade Commission Section 337 investigations, Court of Appeals for the Federal Circuit, and USPTO administrative courts), Prosecution & Counseling (patent application preparation and prosecution, validity and infringement opinions, and portfolio management across biotech/pharma, chemical, electrical/mechanical, software/internet, and design technologies), and PTAB Trials (Inter Partes Review, Post-Grant Review, Covered Business Method reviews, ex parte reexamination, and interference proceedings). Specialized offerings include Standard Essential Patents / FRAND licensing, Hatch-Waxman ANDA litigation, biosimilars, alternative dispute resolution, and TTAB trademark opposition/cancellation practice. Nearly all attorneys hold science or engineering degrees, many at graduate level, supporting technical depth across all major technology areas.
Revenue is generated through professional services engagements billed to enterprise clients (the firm does not publicly disclose rates), supplemented by paid attendance at its annual IP Insights Seminar ($2,000 / $1,300 early bird) and recurring Federal Circuit Lecture Lunch events. The go-to-market model is enterprise field sales built on direct attorney-client relationships, long-tenured international IP relationships cultivated through a 30+ year International Guest Program, and reputation-driven inbound driven by IAM Patent 1000, Harrity Top Patent Firms, and Washington D.C. Super Lawyers rankings. The firm is privately held under partner ownership with no disclosed external investors.
