Law Office of Katsuhiro Arai

The office was founded by Katsuhiro Arai in 2008, after 14 years of experience at one of the leading and largest IP firms in the nation, Knobbe, Martens, Olson & Bear LLP, and 8 years of experience at a patent firm in Japan. We provide full services related to intellectual property law, often representing companies. This includes frequently working with foreign associates and other IP firms on behalf of our clients. We are familiar with both U.S. practice and Japanese practice, and often act as an extended IP division of our client companies. Fully fluent in English and Japanese, we maintain close communication with our clients in their language of preference.

Patent procurement services include drafting and prosecuting patent applications, and conducting patentability studies as well as infringement studies. Prosecution of a patent application requires extensive interaction with the U.S. Patent and Trademark Office (PTO), especially Patent Examiners, via written correspondence and interviews.

We also provide services in trademark procurement, maintenance, and searches.
