Google Inc. recently requested a federal court to declare it had not infringed two patents held by the University of California and its licensee Eolas Technologies. The patents in question were both issued in December 2011, and Eolas sent a demand letter to Google last month claiming that the company was infringing these patents, according to Bloomberg.

In response, Google said the two patents are "siblings" to others Eolas previously attempted to assert against Google in 2009. The attempt was unsuccessful at that time. Google asked the court to declare it had not infringed these most recent patents, and for awards of attorney fees and litigation costs.

Eolas has also asserted other large tech companies have infringed its intellectual property in the past, according to The Washington Post. The company claimed it invented the concept of embedding interactive content online and received payments of more than $100 million from Microsoft on account of that claim before the patents in question were ruled invalid.

The patents in question are related to running applications on a distributed computer media network that allows for interaction with online media as well as search, maps and applications., according to Bloomberg.
