About Us

We drafted patents at the firm youd otherwise hire. Then we left to build one.

WHY FEARN

Fearn’s team is former Big Law—from the people who did the work, not the partners who signed off on it. Learn more.

Protect your work

As technologists, we’ve lived the other side too.

Weeks lost to a redline. Billed by the hour for a process we couldn't see. None of that is the work, so none of that is here. We built the firm we wanted to hire.

INVESTORS

Backed by world-class investors.

We’re proud to be supported by investors who share our vision for how innovation should be protected.

Note from the CEO.

We built Fearn because we lived the problem. Previously, I drafted and prosecuted patents for one of the best law firms in the world. But most of my time was eaten by formatting, boilerplate, and mechanical tasks that were all billed to the client by the hour. Little time remained for the most human-centric responsibilities. 

On the flip side, Angela and I were once PhD students at a top technical school. The pace of scientific research was rampant and all-consuming, and anything otherwise—such as talking to lawyers—seemed unimportant. Only in hindsight did we wish we had devoted more of our time to protecting our innovations. 


Fearn was born out of our experiences from both these worlds. Our vision is to create a universe where scientists and engineers can protect what they’ve built, at a pace and quality equal to that of innovation.
