Investors and partners

The life of a patent, in one record.

PatentOS helps you decide what to file, find what a portfolio is worth, and turn it into income in Japan and the US. A person always makes the final call. We welcome conversations with investors and with US partners: patent buyers, licensees and counsel.

Why now

Why we are building this now.

Nearly half of Japan's patents sit unused.

45.6% of Japan's 1,649,703 patents are reported as unused (Japan Patent Office survey, July 2026).

Japan receives more US patents than any other foreign country.

Japanese companies receive a large share of the US patents granted to foreign applicants (USPTO patent statistics).

Three products.

PatentOS Exchange

Pilot planned for January to March 2027

Buying a Japanese patent, made easy.

A buyer-first patent exchange. AI agents work out the terms; people approve them.

Pre-filing simulation is available in PatentOS Cloud and Enterprise (Japanese edition planned for January to March 2027).

PatentOS works within current law: it gives IP teams and patent attorneys evidence and statistics, not legal opinions. As the legal framework develops, we plan to widen what AI handles, step by step. A person always makes the final decision.

Where we are.

The portfolio review, infringement and valuation workflow was demonstrated publicly at the 2026 IP Information Fair & Conference (September 16 to 18, Tokyo Big Sight). A public demo with fictional data is available at any time.

Investor and partner interest

Start a conversation.

For investors, litigation funders and US counsel. This is separate from product pre-registration. Companies that want to buy or license patents can also pre-register for PatentOS Exchange as a buyer.
