JPO Update

Associated People

The Japan Patent Office has recently updated “The JPO Key Features,” a section of its website that introduces the benefits of filing applications in Japan for global business development. Various pictures and figures of the JPO Key Features mainly show the faster examinations of patent, design patent, and trademark applications at the JPO, encourage enhancing a mix of IP, introduce the Patent Prosecution Highway program, and describe the new Design Registration System.

Japanese clients tend to prefer visual descriptions and explanations for presentations. When we describe patent application systems used between the US and Japan, especially the information regarding the Patent Prosecution Highway and the US-JP Collaborative Search Pilot Program, the pictures and descriptions from this website may be useful to effectively convey our thoughts to Japanese clients.
