01
Boards now answer for IP.
The July 2026 revision of Japan's Corporate Governance Code brings IP under board oversight in Principle 4-1, including monetization.
Investors and partners
The monetization OS for patent owners.
PatentOS decides what to file, finds what a portfolio is worth, and turns it into income in Japan and the US. We welcome conversations with investors and with US partners: patent buyers and licensees, litigation funders and counsel.
Why now
Why now.
02
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).
03
Japan holds more US patents than any other foreign country.
Japanese companies own a large US portfolio that is still largely unmonetized (USPTO patent statistics).
Three engines.
Early 2027
Pre-filing simulation
Decide what to file. Start from an invention disclosure. PatentOS sets out prior art, claim scenarios from broad to narrow, the chance of grant and lifetime cost for each filing route, and a value range, then recommends: file broad, file narrow, keep as a trade secret, publish defensively or do not file.
Available now
Portfolio review, infringement and valuation
Know what you hold. Connect the patents you hold with public product evidence. Claim charts, current and future use, value and maintenance conditions sit in one workspace, so retention, licensing and sale decisions rest on cited evidence.
Planned for 2027
PatentOS Exchange
Buying a patent from a Japanese company used to be slow and opaque. We are making it easy. For companies that want patents for a new product, a market entry, a defensive position or a fundraising. Describe what you are building. PatentOS finds matching Japanese patents and shows each one with a price band, ownership and encumbrance checks, evidence of use and a translated summary.
Today PatentOS works within current law: it gives IP teams and patent attorneys evidence and statistics, not legal opinions. As the legal framework develops, we will widen AI automation step by step, as far as the law allows. 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, companies that want to buy or license patents, litigation funders and US counsel. This is separate from product pre-registration.
