Greetings
Welcome to Hattori and Partners and thank you for visiting our website.
Since the establishment of our firm in 1987, we have specialized in providing intellectual property services to meet the needs of our clients in accordance with the latest laws, precedents and operational standards.
At present, intellectual property have been highly evaluated as a resource in business, and acquisition and utilization of such rights are becoming more and more important.
Inventions brought by innovations are essential business tools for the company’s business growth.
Acquiring invention rights allows you to protect your own business, prevent others from imitating, and maintain your business advantage in the market. You may also gain such advantage by choosing market monopoly, licensing, and patent opening.
Also, by registering a product brand or corporate brand as a trademark, you can enhance the value, allowing the competitiveness of your business. From the perspective of design management, the creation of designs related to the aesthetic appearance of forms, such as industrial products and machines, interior and exterior of buildings, and images displayed on information and communication devices, is registered as a design right to improve business value and prevent imitation.
In addition, selectively acquiring intellectual property rights in Japan and foreign countries and using them strategically according to the market situation and the competition will be an opportunity to expand your business in the global market.
We provide various intellectual property services that meet the needs of our clients, such as applications for rights acquisition, consultation, research, and planning of intellectual property strategies in the medium to long term.
We will continue to make every effort to support our clients’ intellectual property activities.
