Search U.S. Patents
This search tool locates issued U.S. patents by subject-matter content. The non-Boolean search query is aimed at patent abstracts, accommodates any number of query words, and lets you adjust query word weights to refine the search. Find Similar Patents expands a patent selected from the initial search results to patents with similar subject matter.
Search Legal Propositions from CAFC case law
Enter a few words of a general legal principle, and lexcites retrieves a list of matched legal propositions and their citations. Clicking on a displayed proposition links you to the source case, and clicking on the case cite shows you other legal propositions associated with that case.
Patent Prompts
Patent Prompts are patent clues generated by transforming one patent reference in view of another. Use the tool to generate insights for expanding an existing invention, exploiting a novel discovery, or designing around patent claims.
