Japan is one of the leading countries in terms of patent filings, reflecting its strong emphasis on technological advancement and innovation.
Why You May Need a Lawyer

Additionally, when entering into licensing agreements, having a lawyer ensures that the terms are favorable and legally sound. Patent attorneys in Japan can also provide strategic advice on managing intellectual property portfolios effectively.
Local Laws Overview
Key aspects of Japanese patent law include the requirement for an invention to be new, inventive, and industrially applicable to be patentable.

Japan operates on a first-to-file basis, meaning that the first person to file a patent application has the rights to the patent. The standard patent protection duration is 20 years from the filing date, with annual maintenance fees required to keep the patent in force. The law also provides specific procedures for addressing patent infringement, including litigation and dispute resolution options.
