 Thank you for visiting our website . After 15 years of practical experience as a patent attorney since I aspired to a patent attorney at my university age, I established my own firm.

 Patent attorneys are required to have a wide range of specialized skills, including technical understanding, legal knowledge, and language skills. For running a reliable intellectual property law firm, accurate administrative management skill is also essential. However, we believe that it is difficult to provide comfortable and satisfying services to our clients just we have those skills.

 For this reason, we place importance not only on professional knowledge, skills and administrative management skill, but also on imagining what our clients are expecting to us and providing them with useful suggestions through lively close communication. We hope that you are satisfied with technical discussion with our patent attorneys. We also hope that you feel you wish to entrust us with your other cases after meeting with our patent attorneys .

 Due in part to the appreciation of such our policy , we have been patronized by many of our clients even though we are a fairly new firm, having only been established in 2019. We will continue to do our best for further development of our firm with a sense of gratitude and compliance so that we can continue to support our clients’ growth and prosperity for many years to come.
