Three Attorneys Leave Goodwin to Launch AI-Native IP Firm Antheros
Three former Goodwin attorneys launched Antheros, an AI-native IP law firm with subscription billing.
Why it matters: This move highlights a rise in AI-centric legal practices and new client billing models, signaling shifts in IP law firms' operations and client engagement.
- Antheros is founded by three attorneys who left Goodwin Procter LLP.
- The firm uses generative AI to automate routine intellectual property tasks.
- Antheros offers clients a subscription-based billing model rather than traditional hourly billing.
- Goodwin targets 90% AI tool adoption among employees by end of 2026, reflecting broader AI integration in BigLaw.
Three attorneys have departed Goodwin Procter LLP to establish Antheros, a new 'AI-native' intellectual property law firm. The firm specifically leverages generative AI tools to automate routine IP practice tasks, aiming to enhance efficiency and client service quality.
Unlike traditional hourly rates, Antheros offers clients a subscription-based billing model. This innovative approach aligns with growing trends in legal services that challenge the conventional 'point-one' billing system.
Goodwin Procter LLP itself continues to integrate AI broadly across its operations, targeting 90% employee adoption of AI tools by the end of 2026, as reported by Law360. Eric Tan, Goodwin’s Chief Digital and Technology Officer, said being AI-native allows lawyers to focus on strategic advice that clients value most.
This development follows other notable legal tech advancements, such as Falcon Rappaport & Berkman LLP's May 2026 launch of an AI-driven subscription model for litigation and Finnegan's formalization of an AI practice in September 2025 to meet client demand in AI legal matters.
These moves represent a broader shift within the IP legal landscape. Integrating AI and adopting alternative billing reflect evolving business models focused on client value, operational efficiency, and technological innovation.
By the numbers:
- 90% — Goodwin Procter's target AI tool adoption among employees by end of 2026
- May 2026 — Falcon Rappaport & Berkman launched AI-driven litigation subscription model
- September 2025 — Finnegan formalized its AI practice to meet client demand
