Latest Information


   Welcome to Hattori and Partners and thank you for visiting our website.

   In 2017, our office reaches 30 years since it was established in 1987. Since the time of our founding, as a team that has specialized in intellectual property, we have worked to do research about such things as the latest laws, cases, and operational standards.

   In recent years, business management that utilizes intellectual property has drawn attention.

   For example, if you promptly obtain a patent for an invention that anticipates future environmental changes, you can use the patent to get funds for the next stage of research and development.

   In addition, by registering trademarks for product and corporate brands, you can enhance the value of he product or company, and increase the competitiveness of your business.

   Moreover, by acquiring the global intellectual property rights, if you strategically utilize that, you should be able to strengthen your presence in the global market.

   Not only does our office do the application procedure to obtain patents, but we also provide intellectual property right services to meet the needs of our customers, such as consultations, investigations, and drawing up plans for intellectual property strategy. In the future as well, all our staff members will continue to work to achieve our mission of supporting the intellectual property activities of customers in Japan and overseas.
