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

   By using us, you are benefiting from several decades worth of experience and knowledge in the intellectual property industry. We’ve been developing our service since we first formed our institution back in March 1987, and have gained unmatched levels of expertise and professional knowledge in the field.

   But we offer far more than just experience. We have future-proofed our service by voraciously researching the latest legal developments and precedents, as well as analyzing performance trends in the world of intellectual property. When dealing with us, you not only know that you are dealing with the current industry leaders, but also the industry leaders of tomorrow.

   The way that professionals use intellectual property is changing, and as such our service must change to reflect this. The methods in which intellectual property is used to develop business strategies at home and abroad are critical, and so safeguarding those methods has become critical too. With this in mind, we have created new techniques for protecting intellectual property rights, and for facilitating their effective usage across global business.

   Some companies pursue the purchase of intellectual property rights in a proactive and accelerated manner and then put them to practical use; other firms analyze their competition in the marketplace, examine market and enterprise trends and predict investment potentials before strategically purchasing intellectual property rights.

   Whatever your business model, and whatever your IP strategy, we have the expertise and knowledge to help you push your business into positive territory. Our advisory processes are client-driven, and are aimed at helping you acquire and then utilize intellectual property rights in an effective manner.

   From our formative years as a fledgling company in Japan to the present day, we have always striven to forge paths and communication channels between the Asian and Western markets. Using our position in the Japanese market, and our expertise in intellectual property, as a starting point, we have sought to nurture communication between these two global spheres, to our mutual benefit.

   This has helped to form the company that we are today, as well as the service that we offer to our customers. We provide professional intellectual property services to global corporations at a high standard, including consultation, advisory and strategic planning services.

   We’ve come a long way, but still our mission continues. We are a professional intellectual property team with our clients’ interests at heart, and we will continue to support the protection and utilization of intellectual property to meet and exceed their expectations.

   Join us, and let us help you drive your business to where you want it to be.
