Introduction
The patent data in PatAnalyst is organized into two major files: UNIPAT and PREVIEW. The UNIPAT file is the main file for PatAnalyst and it contains all of the patent collections merged into one file. The PREVIEW database contains the most recent data and contains only up to a month’s worth of records. Every Tuesday morning at 8 AM (Paris time: CET in winter and CEST in summer), the PREVIEW database is updated with new bibliographic/family data from the prior week and UNIPAT is updated with full text and other data from the week prior.
Another important distinction about the PatAnalyst coverage is that first publications of related documents are favored and always presented if possible. The following publications such as a US granted patent are not guaranteed to be present and often are not.
Editor's Note:The thorough searcher will want to incorporate the PREVIEW database while searching for prior art, since it has the most up to date information. The UNIPAT database serves its purpose of providing all of the patent document information in one file to eliminate all the time and confusion that switching between multiple files can cause. This is a time saver for the user, although it may cause excess search results if the user is not careful to limit searches by country codes or other criteria.
The lack of complete full text coverage for granted patents hurts those looking to do infringement searching, which relies on claims of granted patents. Additionally, this may cause confusion for searchers who fail to turn up a result with the /pn (patent number) field operator, which searches only publication numbers of FIRST publications, when they are expecting to find a patent document. Because most, if not all, other systems only use one field operator for searching patent document numbers, users will not intuitively understand the proper use of /pn.
