About us

As a company or corporate entity advances in modern society, a key survival factor requires the wisdom gained from IP. For you to properly make your mark in Japan, IP must not only be about what you seek to gain, but the most successful strategy of how to gain it. At Primeworks, we offer you the optimal strategy and support model for successfully achieving your goals.

We at Primeworks file applications for and obtain a multitude of patents and trademarks on behalf of our clients. Our office began as a business engaged in assisting industry-university cooperation with world-renowned scholars. The firm grew exponentially for ten years, and we are now considered to be one of the top IP firms in Japan. Our activities have expanded to support a broad clientele–universities, research institutes, and multinational corporations.

At Primeworks, we place great emphasis on establishing a special understanding through getting to know the client. We are here to serve you, even at a distance of several thousand miles.

Our business continues to be successful in:

  • building strong patents
  • increasing the scope and value of company trademarks
  • protecting our clients’ IP from infringement
  • performing contractual work and licensing of IP

Throughout this series of processes, we are able to support our clients with superior performance and reasonable cost.

Patent Prosecution activity is at the heart of our firm. It forms the keystone of our expertise in other fields: patent evaluation, transactions, litigation all start with the firm foundation of prosecution services we provide. Each of our members provides an integral part of the IP puzzle, and each member has both experience and expertise in all areas of patent prosecution before the JPO.
