Industrial Property Digital Library
From Wikipedia, the free encyclopedia
The Industrial Property Digital Library (IPDL) is a free online service for searching Japanese patents, patent applications, utility models, designs and trademarks. It makes available to the public the intellectual property Gazettes of the Japan Patent Office (JPO).[1] The IPDL provides around 55.5 million documents and their relevant information as published since the end of the 19th century.[2]
The service was originally developed by the JPO, which had provided it since March 1999.[2] The information is now available from the National Center for Industrial Property Information and Training (INPIT), since October 1, 2004.[2][3]
The Patent Abstracts of Japan (PAJ) are accessible through the IPDL web site, and provide access to English abstracts of Japanese patent documents. The PAJ is published since 1976.[4] The PAJ includes the legal status information since January 1993.[4]
