Summary
Full and Partial Text Collections
The following coverage dates were obtained from the system's user guide materials and represent the reported start dates for each collection. Please note that gaps in coverage may exist in any collection due to a number of factors, such as missing documents, scanning errors, OCR errors, even failure of national and regional patent offices to report data. No data source can be considered 100% complete, and searchers should consult as many unique data sources as possible.
