Since 2006, Sakamoto and Partners has been providing high quality and prompt services to our clients.

As part of our services, we strive to foresee complications and propose solutions before these issues can become a problem. Additionally, we endeavor to propose alternatives for solving problems related to our client’s intellectual property rights.

Sakamoto and Partners Strengths

Sakamoto and Partners employs several former Examiners and Appeal Examiners from the Japan Patent Office. Our staff brings a plethora of experience in examining Japanese patent applications and are highly knowledgeable with regard to the Japanese Patent Office examination procedures. In addition, our office not only aides in the acquisition of intellectual property rights, but also helps litigate in the event that our client’s rights are infringed. We also strive to ensure that our clients are granted intellectual property rights to the fullest extent possible.

Another strength is that Sakamoto and Partners employs Chinese, Korean, and United States patent attorneys who can respond to your inquiries in Chinese, Korean, and English. Language barriers can create issues when prosecuting patent, design, and trademark applications in Japan; however, Sakamoto and Partners is able to efficiently and effectively help clients streamline the application process and minimize delays related to miscommunication. Our Chinese, Korean, and Japanese patent attorneys and IP paralegals are also fluent in English.

Furthermore, Sakamoto and Partners has a highly specialized search team for patents, designs, and trademarks at our firm. Most patent firms in Japan do not employ specialized search teams to aid their clients like we do. Our experience and skilled search staff can conduct patent, design, and trademark searches with higher accuracy in a variety of technical fields. Sakamoto and Partners also specializes in patent invalidation searches, and as part of the invalidation searches, we monitor, oppose, and invalidate third-party proceedings, as necessary.

We hope you will use our services when dealing with your third-party observation, opposition, and invalidation proceedings, even if you do not have any prior art publications. Sakamoto and Partners is able to conduct invalidation searches in order to collect prior art publications on our side as well as file third-party observation, opposition, and invalidation proceedings with the Japan Patent Office.

Finally, our Japanese patent attorneys have a vast amount of experience in filing patent applications at the Japan Patent Office for foreign clients. Our staff will carefully assist and explain Japanese patent, design, and trademark law as well as propose the best strategy for obtaining intellectual property rights even if you are not familiar with Japanese intellectual property law.

Sakamoto and Partners is always on your side, providing meticulous representation, protection and enforcement of your intellectual property rights. Additionally, China, India and ASEAN countries have recently been experiencing rapid growth in their economies, and as Japan is close to these countries, Sakamoto and Partners is able to swiftly aid our clients in these countries as the time difference is minimal.

Please ask Sakamoto and Partners to become your new intellectual property hub in these developing Asian areas.
