The Mercari Group’s systems are supported by a variety of open source software. As a beneficiary of the enormous contributions made by the open source software community, we believe making a contribution to innovation in the world by publishing technology accumulated through the development and operation of our services, such as Mercari and Merpay, as open source is the right choice. Hence, the Mercari Group endorses the activities of OIN which protects innovations with open source from patent risks.
