Patent Retriever is a new service for downloading patent documents. Launched just days ago (May 30), it will retrieve US, EP and WO (PCT) patent documents in PDF format fairly quickly, although I haven’t timed it against other similar services. Users may download single documents or up to ten documents in batch download mode. It appears to retrieve some US documents from the EPO’s esp@cenet database and some from the USPTO website. However, it does not appear to retrieve pre-1836 patents (X patents) or additional improvement patents.
