Participation and registration of technology in the WIPO GREEN International Platform for Environmental Technology

Meidensha has participated as a partner business in WIPO GREEN since March 2022. The international platform is operated by the World Intellectual Property Organization (WIPO) of the United Nations to promote the use and diffusion of environmental technologies.

We have also registered certain of our environmental technologies and related patents in the WIPO GREEN database. These include an ecotank-type vacuum circuit breaker that does not use greenhouse gases, a ceramic flat-sheet membrane for water treatment devices that contributes to the effective use of water resources, and a charging and discharging device for battery testing that improves accuracy and efficiency in battery research and evaluation.

We will continue to register Meidensha’s environmental technologies and disseminate them widely around the world through WIPO GREEN. This will give more people the opportunity to use them and help achieve a sustainable society by, for example, decarbonizing society and adapting to climate change.

[About WIPO GREEN]
Established by WIPO in 2013, WIPO GREEN is an online platform that promotes the transfer of environmental technologies by connecting providers of such technologies with those who wish to use them. The platform maintains a registry of environmental technologies and needs for such technologies around the world.

WIPO GREEN Partners are members of the WIPO GREEN Advisory Board that work with WIPO to guide the activities of the WIPO GREEN platform. They include public and private organizations who support, advise, and otherwise work on behalf of WIPO GREEN.
