Keiryo Packaging has both a number of approved national patents and various pending patent applications. Given the global nature of the packaging industry, Keiryo Packaging has established a broad geographical patent coverage for its technology basis. Specific details on the legal status of the patents and patent applications can be found on the Patents page of our website.
Aside from our various IP assets, Keiryo Packaging also holds proprietary know-how which has intentionally not been converted into patent claims.
