The coverage in Qweb is based on the Questel database coverage also shared with QPAT and Questel on Imagination. Individual files may be loaded for searching or user customized clusters can be created to search multiple files at once. Many individual country patent databases are available to search in full text, complimenting the general array of European Patent Office Collection (EP), Patent Cooperation Treaty Collection (WO/PCT), and United States (US) coverage.
Qweb has coverage of patent documents from a wide array of national and international sources including the coverage from the standard sources such as the US Patent Office (USPTO), the European Patent Office (EPO), and the World Intellectual Property Organization (WIPO). Additionally, other major countries such as Germany, Japan, France and Great Britain have extensive coverage and some other countries of note such as Austria, Belgium, and Switzerland also have coverage within Qweb. In this article, the major collections will be discussed in depth and the minor collections will be briefly mentioned. Further information can be found in the latest version of the Questel Database Catalog
Questel hosts a wide array of full text patent databases from individual countries combined with important value added patent files compiled exclusively by Questel including family data related files FamPat and PlusPat. The patent coverage that a user can access through Qweb is impressive and compares very favorably with the other top patent search systems out there.
