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 from your end.

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.

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.

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.​

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.

Once your patent/trademark applications are granted, we will enter these into our docket system, and provide you with estimated costs in advance and timely reminders.

Complex Cases

We have devoted ourselves to professional IP work especially in difficult and complex proceedings, including appeals and oppositions, and our firm's success rate in such proceedings is significantly high.

Quality Service Guarantee

We believe that Allegro IP is the sole Japanese IP law firm that offers foreign clients a quality service guarantee commitment. We have prided ourselves in high-quality services from the start of our firm and we are always trying to provide our best services to clients. However, if you find any unsatisfactory issues with our services, please request us to work over your cases as you deem necessary. At least two partner IP attorneys will review the case and try to follow your request as much as possible. We will of course absorb any additional expenses related to this service. It may be unfortunate for us to receive such a request, but we view our clients’ demands as opportunities to improve our services for future cases, and we hope that our clients will enjoy our services in the long term.
