Google patent search allows you to search for patents that are registered with the government. Their advanced search allows you to state several search parameters. You can search by patent number, company or individual who was given the patent, date of getting the patent, date of filing the patent and several other options.
When you search all the patents filed and assigned to Google, Inc. you will get back a plethora of information. If you want to know what Google is up to in new developments, you can search by their most recent filings. 
Recent filings for 2010 include search query optimizations for business listings. Businesses will benefit from the new patent because it will deliver more relevant business results. For example, when a searcher does a search for film development an association can be made with the words photo finishing even though the two words have no actual words in common. Refining a process of categorizations for businesses can help return better search results.
Google uses training data to artificially learn from search entries. According to the patent filing, the first thing that needs to be done is to create business categories relevant to specific search queries. The categorization classification component can learn from the search queries and business categories, based on training data. Data is selected from predefined yellow page listings, categorized business websites, consumer report information, restaurant guides, query traffic data and advertising data. The input is then stored as a series of possibilities.
If you are totally baffled by now, just know that business searches are going to become much more relevant, which is good news for business websites.
Try a search in the Google patent search and see what you come up with. Perhaps you’ll search by patent number and learn that patent number 1,000,000 was for an improvement made in vehicle tires, patented in 1911.
