VCs can't get enough of legal startups. Andreessen Horowitz just invested in one taking work from patent lawyers.

• Fearn, a startup building tools for patent drafting, has raised $5.5 million in seed funding.
• Investors include Andreessen Horowitz, a prominent backer of Harvey, and Kindred Ventures.
• Patent law has quietly become a hotbed of startup activity in the fast-growing legal-tech sector.

Kim said many of Fearn’s competitors came to patent drafting as outsiders chasing a “hot business problem.” Fearn’s advantage may be that one of its founders lived the problem.

“For me, it really started with: My old job kind of sucked,” Kim said. “This really can be automated. It doesn’t have to suck.”
