Try Dealroom →. It will use the funds to start buying dormant patents from companies and turn them into revenue.
What does the company do? Founded in 2020, IPdefine uses a proprietary database and AI to analyse the economic value of patents and other intellectual property. It supports companies, universities, and research institutions with patent evaluation, licensing, and sales.
What's the endgame? Until now, IPdefine has advised patent holders. It will now purchase and manage patents itself, then license or transfer them to companies that can put them to use. The money will go mainly toward acquisitions and building out post-purchase management.
Why now? Japan is one of the world's largest patent holders, with roughly 2.1 million valid patents in 2024, third behind China and the US, according to the World Intellectual Property Organization. Many sit unused, generating no income despite related products existing in the market.
The company's database holds some 500 million records on patents and market products, which it uses to flag patents with likely economic value and assess potential damages from infringement.
What's the vision? "What we aim for is not simply to buy patents," said chief executive officer Mitsuhiro Okamoto (translated from Japanese). He wants to build a market where technology that has stopped being used internally can generate value elsewhere.
IPdefine also plans to securitise patents as investment assets, letting investors participate in the IP market and shifting patents from held assets to circulating ones.
The signal: The round is modest, but it points to a growing effort to make intellectual property a liquid, tradable asset class. As Ichigo put it, IPdefine's move is "an important first step" toward a market that turns idle patents into new value.
