Masayuki Shobayashi

President at Shobayashi International Patent & Trademark Office

Masayuki Shobayashi is the founder and president of eponymous IP law firm Shobayashi International Patent & Trademark Office (SIPTO).

Mr Shobayashi has served as a university professor and incumbent deputy chair for the Japan Patent Attorneys Association. He is also an author and academic authority on Japanese intellectual property with numerous publications on IP issues. Mr Shobayashi regularly lectures on law, technology and the Japanese Patent Bar.

Due to Mr Shobayashi’s close connection with the Japan Patent Office (JPO), SIPTO currently employs the highest number of former JPO employees (ie, judges, directors and patent examiners) in Japan. This ensures that SIPTO provides the highest level of expertise in IP law, unrivalled by any other IP firm in Japan.

SIPTO’s expertise also extends to IP searches, analysis and valuations, and the sale and purchase of IP rights. Mr Shobayashi handles one of Japan’s largest caseloads for IP due diligence on investments and IP valuations for finance (specifically for IP mortgage finance).

Mr Shobayashi focuses on expanding IP portfolios and asset management, IP valuation appraisals and the management and consulting practice of SIPTO. In addition to his clientele of national and international companies, he promotes and specialises IP rights for business models, providing routes of monetisation and protection for the next generation of entrepreneurs.

With a diverse focus and the highest level of expertise, Mr Shobayashi continually aims to spread this reputation throughout the global market, from sole entrepreneurs to international companies.
