Superior Discovery and Ranking


PatentsSearcher, which has started as a university project, applies cutting edge research on searching and relevance ranking algorithms.


We found that existing patent search engines just apply existing Information Retrieval algorithms to the patents database, viewing patents as regular text documents. This simplistic view leads to suboptimal search effectiveness.


In contrast, PatentsSearcher's algorithms have been created and customized for the special properties of the patent domain, after interviewing many patent attorneys and domain experts. This leads to the discovery of relevant patents, even if they are not obviously related (e.g., they do not have the query keywords in the abstract or title).


Give it a try to find results that other search engines would miss.
