Japan
The only patent collection currently available on JP-NETe is Japanese unexamined patent documents. The two components of this data are the Patent Abstracts of Japan (PAJ) collection and a proprietary machine translated collection. PAJ typically has a lag time of around three to four months. This means that from the time unexamined patent documents are published in Japan, it takes three to four months for JAIPO (the Japan Patent Information Organization) to create corresponding English titles and abstracts, and publish the information. JP-NETe's machine translated document data bridges this gap because this data is produced weekly. When the corresponding PAJ data is released, it replaces the machine translated data within JP-NETe.
All available documents have English titles and abstracts, as well as inventor, assignee/applicant, publication number, publication date, application number, application date, and IPC Classifications.
Unexamined patent document data is available from January 5, 1989 forward.
Editor's Note:Most search systems with access to PAJ data extend back to 1976, the first year of available PAJ data. This is even the case for free systems such as FreePatentsOnline. The lack of this data in JP-NETe is a major detriment, especially since it is a system that only has one source of data.
The lack of any full text data is also a disadvantage when compared to for-pay search systems with full text documents in English such as PatBase, QPAT, and Thomson Innovation. This is of particular detriment to searchers trying to identify and use the available figures, which are most often listed in the "Description" section of the patent document. This section is unavailable in JP-NETe.
The lack of Japanese granted documents is also notable for a system solely featuring Japanese patent data. Under a 1996 Japanese patent law, applicants can forgo the traditional examination process (which always involves a published unexamined patent document) and choose to undergo an accelerated examination. The resultant "B1" granted documents will not be included in the PAJ data and therefore are not currently covered by JP-NETe.[1]
On the other hand, machine translated data from the most recent three to four months of unexamined patents is a strength of JP-NETe and appears to be the most timely way for English searchers to acquire and search Japanese patent data.
