by IP Rich
The AI workspace for patent evaluation and portfolio review
Decide what to file, find what your portfolio is worth, and turn it into income in Japan and the US. AI gathers and shows the evidence; your team and counsel make the final call.
IP Rich exhibited at the 2026 Intellectual Property Information Fair & Conference, held September 16 to 18, 2026 at Tokyo Big Sight, East Hall 3 (booth 3-D38).
Thank you to everyone who visited our booth. The portfolio review, infringement and valuation flow we showed there is available any time in the public demo, which uses fictional data. Pre-registration for PatentOS is now open.
Pre-register02 / Three engines
What you learn before filing informs the portfolio review, and the review prepares the sale or licence. Every analysis is logged as a matter that stays with the patent.
Early 2027
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.
Decision support for in-house IP teams and patent attorneys. It shows evidence and statistics; it is not a legal opinion.
Available now
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.
See the review flow in the public demo, which uses fictional data.
Planned for 2027
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.
Selling? List in minutes and the AI prices the patent. Every listing ships priced, encumbrance-checked and with evidence of use. Patent Capital can make an instant offer, and US negotiators are optional.
Roadmap
Why now
01
Organize patent numbers, claims, remaining terms, and maintenance conditions. Start with the questions your own portfolio raises.
02
Map public product sources to individual claim elements. Keep supported matches separate from gaps that still need investigation.
03
Review present and future use potential, earning potential, and evidence requirements to inform retention, licensing, or sale.
02 / Workflow
Portfolio review, evaluation, sources, claim charts, and revenue scenarios. Keep the evidence and open questions connected as work passes to the next reviewer.
See the evaluation and proposed retention decisions together for each patent.
Review present and future third-party use and earning potential. Leave missing information unassessed.
Read the source text and mark relevant passages. Separate what the evidence supports from what needs another check.
Compare claim elements with product evidence and identify the next checks for AI, technical, and IP reviewers.
Compare assumptions for sales, royalty rates, and risk. Scenarios are not a guarantee of income or a patent sale price.
Reading the evaluation
Use the evaluation to consider portfolio decisions and licensing strategy. Read the evidence and assumptions alongside the score.
Check claim scope against products and services in use today.
Review sales exposure, royalty assumptions, costs, and remaining term.
Consider possible uses, adoption timing, and the supporting evidence.
Compare when income might arise and under which conditions.
Try source highlights and notes, responsibility labels, and revenue scenarios with adjustable sales, royalty, and risk assumptions.
Evaluation features are under development and validation. The public demo uses prepared examples, including example agent answers in the source viewer. Revenue scenarios use assumptions and do not establish a patent price or guarantee future income.

04 / The agents
Specialist AI roles support research, claim breakdown, and evidence checks. Technical reviewers check product facts; IP reviewers and counsel interpret the claims and make the final decisions.
↳ The public demo uses prepared examples. Evaluation features are under development and validation. Agent answers in the source viewer are demonstration examples. Pilot scope is agreed individually; NEXT means planned functionality.
