The "Blue Book" is comprehensive guidelines and explanations regarding Japanese patent laws and practices officially published by the Japan Patent Office (JPO). Primarily, it serves as a detailed commentary on the Japanese patent law. The Blue Book offers insights into the interpretation and application of the law.

The formal title of the Blue Book can be translated as "Article-by-Article Commentary on Japanese Industrial Property Law," but this is not the official English name published by the JPO.

Who is the Blue Book intended for?

The Blue Book is intended for patent practitioners, patent attorneys, and anyone involved in the patent process in Japan. It serves as a comprehensive guide and reference for understanding Japanese patent laws, their interpretation, and their application by the JPO.

The Blue Book contains interpretations of the provisions of the Japanese Patent Law, as well as the history of its enactment and revisions, making it an indispensable document for these individuals. Additionally, it is used by candidates preparing for the Japanese Patent Attorney Examination, as questions based on the Blue Book are included in the exam.

What are the differences between the USPTO's MPEP and the JPO's Blue Book?

The Blue Book is similar to the Manual of Patent Examining Procedure (MPEP) used by the United States Patent and Trademark Office (USPTO), providing essential guidance on patent practices and procedures in Japan; however, the MPEP is primarily a manual for USPTO examiners, whereas the Blue Book is not a manual for the JPO examiners. For patent examination, the JPO examiners use a different document called the "Examination Guidelines for Patents and Utility Models."

In addition, the Blue Book covers a broader range of intellectual property laws including patents, utility models, designs, and trademarks, whereas the MPEP primarily focuses on patent law and procedures, including design patents, but does not cover trademarks.

How extensive is the Blue Book?

The Blue Book is available in PDF format on the Japan Patent Office website and spans 2,401 pages in Japanese. This is the case for the 22nd edition, published in October 2022.
