Do you trust AI-driven services to handle sensitive legal documents like patent applications?

Fearn has launched an AI-native patent prosecution firm backed by $5.5 million in funding. The company aims to disrupt the patent process by offering expedited filings at a fraction of traditional legal costs.

Why it matters

Founders established the firm to address high costs and long turnaround times that startups face when seeking intellectual property protection. The platform seeks to make the patent process more accessible for early-stage businesses by leveraging automation.

Fearn raised $5.5 million from investors and reports gross margins above 80 percent. The company processes provisional filings in three business days for $2,500, significantly undercutting conventional market fees of $18,000 to $40,000.

The details

The firm utilizes a proprietary system named FearnOS to map patent claims to supporting figures and text, drafting applications in roughly 30 minutes. Every AI-generated filing is reviewed by former Big Law patent experts to ensure quality and compliance.

Fearn publicly launched its patent firm on September 23, 2026.

Market Landscape

Fearn enters a global patent market worth $14 billion annually that is currently dominated by high-cost traditional legal services. By automating the drafting process, the company seeks to challenge established firms that typically charge startups between $18,000 and $40,000 per application.

Startups can now secure provisional patent filings in three business days for a fixed cost of $2,500. The firm offers a full refund of its $9,000 non-provisional drafting fee if an application fails to receive any allowed claims, providing a performance-based safeguard for founders.

The takeaway

The entry of AI-native firms into the legal sector signals a shift toward automation in historically expensive professional services. Founders looking to protect intellectual property should weigh the speed and cost benefits of AI systems against the traditional counsel of human attorneys.
