Access to patent information isn’t just important for inventors looking to protect their inventions but also for companies looking to license new technology.  Therefore, the National Center for Industrial Property Information and Training runs an online search tool called the Patent Licensing Information Database that freely allows the public to search for information about registered patents.  There is no fee to use the service and no registration is required.

In addition to companies looking to license patents, this search tool is also useful for academics, researchers and students who may find themselves in need of information regarding a Japanese patent.  In addition to the patent number, the Database will display the date of publication, a brief abstract and a technical drawing where available.

If you have any questions about licensing intellectual property please contact our office for a legal consultation.
