Latent value,
made patent.
A path forward for the technology you hold.
Technology you no longer use may still matter to another product or market. We review claim scope, product evidence, remaining term, and your business priorities to consider a practical path for each patent.
We check the rights and markets in the relevant countries before pursuing licensing opportunities.
Discuss your patents
Every invention deserves individual attention.
Review the patent, the status of the rights, product evidence, and potential uses, taking the owner’s priorities into account.
Patent numbers · Remaining term · Products · Existing agreements
Discuss acquisition eligibility and contract terms for the specific patents and objectives. An acquisition proceeds once the terms are agreed.
Outright purchase · Upfront payment + sharing · Revenue sharing
After acquisition, we lead negotiations and use of the rights in Japan and abroad, with responsibilities defined in the agreement.
Conversations grounded in technical and patent evidence
We bear the evaluation, research, and negotiation costs.
Acquisition decisions and contract terms are agreed individually. Neither a purchase nor a revenue outcome is guaranteed.
Besides selling to us, you can look for a buyer on PatentOS Exchange, a buyer-first patent exchange and one of the PatentOS products from IP Rich. A pilot is planned for January to March 2027, starting with curated listings. If you wish, Patent Capital can make an instant offer before you list. PatentOS is a separate business from Patent Capital, and using PatentOS does not constitute consent to sell a patent.
