Google Snags Programmable Search Engine Patent
April 11, 2010
Short honk: The programmable search engine invention has been granted a US patent. Filed in august 2005 and published in February 2007, the PSE provides a glimpse of the Google’s systems and methods for performing sophisticated content processing. Dr. Ramanathan Guha, inventor of the PSE, has a deep interest in data management, the semantic Web and context tagging. You can download a copy of US7693830 from the USPTO. There were four other PSE patent applications published on the same day in February 2007, which is a testament to Dr. Guha’s ability to invent and write complex patent applications in a remarkable period of time. The PSE is quite important with elements of the invention visible in today’s Google shopping service, among others.
