We develop the patent strategy and build the patent portfolio for venture-backed startups on a project-based, flat rate basis. We function as a fractional in-house patent team, responsible for mining, prioritizing, capturing, and writing patent applications on the most valuable inventions.

We have helped over 600 startups develop their patent portfolios, which have increased exit valuations and deterred competitor patent lawsuits. If interested in our services, please apply here.

We created and financially sponsored a philanthropy fund for the founders of our clients. This fund empowers founders to give now — despite their cash and time constraints — by pooling together 1% of their founder stock.

The philanthropic fund, which has had two successful company exits across a dozen members, has provided over $650,000 to 20+ non-profits working to solve some of our most pressing social justice and environmental issues.
