Selling inventions

     Tekcem provides inventions to companies that use open innovation to improve their technology. We have a broad-ranging expertise and competence to patent transactions in the area of electrical engineering. Unlike brokerage firms which only mediate between a buyer and a seller, we only offer for sale patents and patent applications owned by the Excem group (to which Tekcem belongs) and which are within our field of technical expertise. Thus, we can provide a strong support to our customers. The assets offered for sale have usually been invented within the Excem group, but we can also sell patents that were purchased by Tekcem.

     Tekcem sells inventions covered by a granted patent or a pending patent application. We sometimes license inventions. We often also sell the related know-how, including technical reports, simulation results, specific simulation tools, and/or training.

     Since its incorporation in 2009, Tekcem has handled the patent families listed in the following table.
