Patent Invalidity and Technical Information Search in Japan

Patent Invalidity Search

When you need additional information for the patent invalidity on IPR (Inter Partes Review), PGR (Post Grant Review), Re-Examination or investment, searching related information in Japan may be extremely useful.

Japan has a large amount of patent information that is very well organized by domestic patent category (e.g. F-Term) and it is very efficient to find necessary information. We see many of full text Japanese patent information that is translated into English by software, however, it is far away poor quality of patent invalidity consideration or Investment therefore we search, in Japanese, in Japan with US IP knowledge for your argument.

There are also many product manuals, product guide, college thesis, publication, market report that is written in Japanese, not available over the internet, but we can find out relevant information for your specific needs.


Technical Information Search

For your investment or business expansion into Japan, you may want technical information or market overview from technical prospective. We can find our relating information based on your unique business needs and happy to discuss over phone. Our team has more than 20 years IP based business experience in a business corporation, instead of in pure IP industry.
