Hiroshima Office is situated in the very center (Tatemachi, Naka-ku) of Hiroshima City, the biggest city in Chugoku-Shikoku region. Hiroshima Office as a branch office of the “large scale, international, integrated office” has a mission to offer, in particular, a Chugoku-Shikoku region-based total intellectual property service. Our well-experienced staffs capable of managing individual situations work hard for accomplishing this mission.

Specifically, we can provide the following service from Hiroshima Office.

1. Service Concerning Overseas Applications

In HARAKENZO WORLD PATENT & TRADEMARK, highly specialized patent attorneys, staffs having ph.D., patent engineers, and translators are present in all intellectual property fields. By taking advantage of this office scale, Hiroshima Office offers a strong support for intellectual property strategies in each country.

We also provide intellectual property information on emerging countries, such as Brazil, India and so on.

5. Anti-Counterfeiting Support

It is impossible to imagine our life without imported goods from overseas. Especially, Hiroshima has not only Hiroshima Port and Fukuyama Port which are linked to the major ports of the world, but also Hiroshima Airport having established air routes to major cities in other Asian countries. These platforms have established a network linking to the world. It is therefore essential to take anti-counterfeiting measures.

Hiroshima Office supports your anti-counterfeiting strategies including suspension of clearance of infringing products at the customs.

7. Our Contribution to Society and to Peace

From experiences as a victim of nuclear bombing in 1945, Hiroshima has continued to appeal to the international societies for abolition of nuclear weapons and lasting peace of the world. Through our business activities in Hiroshima, we, staff members in Hiroshima Office, are deeply impressed with the enthusiasm of people at the time of postwar reconstruction. We would like to express our thought by carrying out activities for "contribution to society and to peace", which is one of our basic principles.

We understand that there is no complete ideal form for activities to contribute to society and to peace. Even if what we can do is very small in view of the goal of achieving the lasting peace of the world, we would like to honestly go forward step by step to reach for the goal.

Takashi SUGA Takashi SUGA, born in 1966, obtained an MS in Material Physics from Osaka University. The targets of his research include Magnetism and Super-Conductivity. His specialty covers Electricity, Mechanics and Physics. He is presently a member of JPAA.

Now, I have a post at Hiroshima office.
A product is evaluated, for example, from the viewpoint of its usability, good design, or attractive brand name, and creation of such intellectual property as usability, good design or brand name can be a source to produce a business opportunity. However, if such created intellectual property is copied by another person with ease, the business opportunity will come to nothing.
I believe my duty is to preserve an important business opportunity of our client in Chugoku region securely and lastingly through my daily works with my geographical advantage of my hometown Hiroshima.
