Why this company matters

Finnegan, Henderson, Farabow, Garrett & Dunner positions itself as the dominant intellectual property law firm for the additive manufacturing industry, offering end-to-end services from patent drafting to Supreme Court litigation. Founded in 1965, the firm has built a specialized practice group focused on 3D printing and AM technologies, distinguishing itself from generalist IP firms through depth of technical expertise in AM processes.

The firm's core offering spans patent, trademark, copyright, and trade secret law, with particular strength in patent prosecution and post-grant challenges. Finnegan files over 3,000 USPTO patent applications annually, more than any other private firm, and reports a 95%+ success rate in trademark proceedings. Its attorneys combine legal strategy with proprietary industry knowledge of AM technologies, protected through attorney-client privilege and trade secret protocols.

Target clients include AM companies, 3D printing startups, and established manufacturers adopting additive processes. Notable customers include AbbVie, Bausch & Lomb, BMW, Eastman Chemical, Eli Lilly, and Ghost Robotics. The firm serves verticals spanning aerospace, defense, automotive, medical devices, consumer products, electronics, and biotechnology.

Finnegan's primary competitive moat is scale: with over 350 IP professionals dedicated to AM and related technologies, it is roughly three times larger than the next closest specialized IP practice. The firm is ranked Band 1 in Chambers USA for patent work and has eight partners recognized in MIP's Top 250 Women in IP. Revenue reached $349.2 million in 2021, and the firm employs approximately 912 people across five continents. A key open question is whether the firm can maintain its allowance rate advantage for AM patents as the technology matures and prior art expands.
