Fearn has launched a patent prosecution firm that uses a proprietary system called FearnOS to generate patent applications. The company, which has secured $5.5 million in funding, offers fixed-price filings to compete with the $18,000 to $40,000 typically charged by conventional firms.
Why it matters
The firm intends to disrupt the $14 billion global patent market by reducing the cost and time barriers that currently challenge the 150,000 annual patent filings from early-stage companies. By utilizing automation, the service seeks to replace traditional legal workflows that have historically required significant manual labor.
FearnOS drafts applications in 30 minutes by representing patents as a graph that maps claims to supporting text and figures. The firm claims to achieve gross margins above 80 percent, with provisional filings delivered in three business days.
The players

The details
FearnOS functions by structuring patent data into a network graph that links individual claims to their corresponding descriptive text and visual figures, automating the initial drafting phase. Every application generated by the system is reviewed by former Big Law patent experts to ensure quality. The process represents a shift from conventional drafting methods, which typically require 30 to 40 hours of manual effort from human attorneys.
Timeline
Fearn publicly launched its patent firm on September 23, 2026.
The Tech Race
The firm enters a $14 billion global patent market currently dominated by traditional law practices with high human-labor requirements. Its adoption of automated graph-based drafting puts it in direct competition with conventional legal service models for the 150,000 startup patent filings occurring annually.
Startups can now opt for provisional filings at a fixed cost of $2,500 with a three-day turnaround. The company guarantees a full refund of its $9,000 non-provisional drafting fee if a filing fails to secure any allowed claims.
The takeaway
Fearn is betting that AI automation can fundamentally lower the barrier to entry for startup intellectual property protection. Watch for future performance data on their granted claims, as the firm plans to expand its AI capabilities into patent families and international filings.
