Our Services
PCT National Phase Entry into Japan

Please just let us know your PCT application number. We will check the status and let you know the due date and necessary documents to be sent to us.

Patent Translation

Only qualified patent attorneys are in charge of translation services. We do not use translation agencies, whose translations are inferior in quality and do not satisfy the formality requirements.

Prosecution before the JPO

We have prided ourselves in high-quality services from the start of our firm. The same patent attorney is responsible for handling each case entirely from the filing through prosecution.​

Trademark Filing in Japan

Please provide us with your logo/mark and goods/services to be designated. We will carefully review them and provide some proposals to comply with the Japanese practice.

Administrative Work

We believe that administrative work is very important in the IP field. Our administrative staffs are well experienced and we apply a triple check process to each case.

Q By when a PCT national phase entry into Japan must be filed ?

If you already filed a PCT application in your jurisdiction, it is required to file a Petition for Entry within 30 months from the international filing day or the priority date, whichever is earlier.

Basic Filing Fee: JPY 60,000

I have worked with a number of different patent attorneys in the US, EP and other countries. Among all the attorneys, I have really enjoyed working with this firm and very much appreciate their help with our patent applications. Thank you for taking good care of our applications.
