I am trying to automatically retrieve patents claims from different jurisdictions. Open Patent Services allows to retrieve patents Claims from WO, EU, and several other patent offices whereas no coverage for US jurisdiction is provided. USPTO PatentsView supports fetching abstracts from US patents but no Claims. To adhere to Terms of Use of patent search engines, I don't want to use a web crawler. What patent search engines do allow to automatically retrieve Claims of patents and patent applications from USPTO patent databases (via API)?

  • I don’t know if it does all you want, but you should check out lens.org/lens – Eric Shain Oct 31 '17 at 0:57
  • Thanks, it is really great tool but it lacks an application programming interface currently. – Brut Oct 31 '17 at 1:15
  • I thought they were adding it. The Lens is academic so it might be worth contacting them. – Eric Shain Oct 31 '17 at 2:55
  • It doesn't handle claims but [Pair bulk data] (pairbulkdata.uspto.gov) is the only other patent api I'm aware of not mentioned so far. – mustberuss Nov 23 '17 at 17:05
  • Lacking an api one option would be to download the 10G claims file from patentsview and pull what you want from it patentsview.org/download It's not ideal but it might be your only option? – mustberuss Nov 23 '17 at 17:38
