GetThePatent.com offers free searching and patent text retrieval for US patents issued since 1976. We also offer free 5 patent guest accounts, allowing you to freely retrieve up to five complete patent image documents.

Our patent image archives include US, EPO, WIPO, British, French, German, Japanese, and Swiss patents. The patents are distributed in the hyper-compressed CPC format, which averages only 1/6th the size of the legacy TIFF or PDF files used by other services. This means that the images download 6 times faster. And, all of the patent pages are distributed in a single file. This means you can print, copy, or email the entire document with a single command.

Alternatively, the EPO offers free access to all US utility patents issued since 1920. The patents are distributed as single-page PDF files. Non-utility patents are not available.
