United Kingdom
QPAT obtains bibliographic data and drawings for the United Kingdom's patent documents from the EPO, and full text data (description and claims) from data producer Univentio. The text was created by OCR technology, and may contain some misinterpreted characters or incomplete text.
Full text records for the United Kingdom’s published applications are covered from 1920. Drawings are present for approximately 35% of the records.
These full text files do not contain updated classification data. They only contain the classification data published for the record at time of issue. Since both IPC and ECLA classifications are commonly revised and updated, searching by classification in these files will not be using the most recent, updated data.
Editor's Note:Interestingly, the documents contain indexing by the United Kingdom’s own (now retired) patent classification system. These can actually be searched via QPAT’s command line interface, using the command /UKCL. UKCL formats are comprised of a three character alphanumeric heading, and a three-to-six character sub group term. The heading and term are separated by a slash in the database. Although the inclusion of these classifications might be seen as an advantage, it is likely that any revisions and subsequent re-classification of these files will not be reflected in the QPAT database, since full text files do not contain updated classification data.
