Abstract
Methods, systems, and techniques for facilitating searching for patent related literature are provided. Some examples provide a Patent Related Publication Search Engine (“PRPSE”), which enables users and or programs through the use of an application programming interface (“API”) to iteratively find patent related publications such as issued patents and patent application publications. In typical operation, based upon input text, the PRPSE determines predominant keywords found in the text and locates a set of patent related publications most closely related to these determined keywords as search results. In some examples, the PRPSE determines the set of patent related publications most closely related to these determined keywords both by full text searching of a corpus of patent related publications for all of the patent related publications that contain the predominant keywords and by finding all correlated patent related publications through citation analysis.
