"NASA Technology Transfer Portal" which can search NASA's patented technology that can be used for free

NASA, the US Aeronautics and Space Administration, which continues space development for about 60 years since the late 1950s, has acquired numerous patents on technology obtained during development. Some of them already have patent rights disappearing into public domain, but NASA's site is able to search for such patented technology.

This page is an effort to open the technology of NASA to the world widelyTechnology Transfer ProgramWhat is being done as part of. As in this page, a page that allows you to search past patent technologies has been published, and also technologies that are valid for patent rights can also be used free of charge if certain conditions are met. However, although it can be used for free for the first three years, it is necessary to pay royalty and administrative fee to the inventor at the stage of profit generation.
