The firm is staffed by 20+ attorneys and patent agents with an average of over 20 years of IP practice, 50% holding advanced degrees and 30% holding Ph.D.s in their respective technology areas, and over one-third with bilingual capabilities — supporting deep technical representation across life sciences, biotech, pharmaceuticals, medical devices, electrical/electronics, mechanical, chemical, computer science, financial technology, blockchain, horticulture, and agriculture.

Revenue is generated through professional service fees (hourly rates, matter complexity, attorney experience) on a quote-based, multi-year engagement model typical of law firms, with no publicly disclosed pricing. Go-to-market is direct, sales-led client engagement supported by content marketing, email newsletters, industry seminars and CLE programs, press releases, and organic social media. The firm has no outside investors, parent company, or external ownership, and is owned and operated by its partner attorneys.
