Google Is Granted Two More Patents

The US Patent Office has issued Google two more patents.

One patent, for a similarity search engine - to check duplicate content - was first filed in 2001.

The other, Google's Digital Mapping Systems patent, describes 'various methods, systems and apparatus for implementing aspects of a digital mapping system'.

The similarity engine has had variations filed by IBM and Hitachi, according to a report by VNUNET.
