It’s essential to provide a clear and detailed description of the invention (termed “specification” in legal terms), along with any necessary drawings, photos, and examples, to support your patent claims effectively.

Patent Prosecution Highway (PPH) program is another valuable tool for expediting the examination of patent applications in Japan.

This helps reduce duplication of work, facilitates faster patent grants, and reduces costs.
