Our Advantage

When it comes to the Japanese market, foreign companies, especially SMEs, often have difficulty finding IP law professionals willing to fight for them. This is where we come in. Headquartered in Tokyo, Kimura & Partners is a boutique IP law firm passionate about serving clients’ IP interests in Japan and globally.

Japan’s business climate and IP practices are different than in other countries. So also are its rules and systems for granting and handling disputes regarding Intellectual Property rights. For IP success in Japan, foreign companies must have an IP Partner with deep experience and success with the Japanese IP system.

It may surprise you to learn that over 90% of patent applications are initially rejected by the JPO. However, our unique capability and approach result in an exceptionally high registration success rate for our clients. We are also consistently successful in defending our clients in IP disputes and legal actions.

Since our establishment in 2001, we have completed over 1,400 Patent Applications, 1,000 Patent Registrations, and 1,000 TradeMark and other IP registrations. SMEs and their legal or IP advisors worldwide routinely rely on Kimura to handle their IP needs in Japan and their other markets.
