A new report reveals Google isn't merely targeting cell phone markets but may be going after video games, TV, and mobile e-commerce as well.

The research conducted by Evalueserve, a global consultant and research firm, found that Google, IBM, Microsoft, and Yahoo are the most active filers.

Google patents turned out to be concealed competitive intelligence and less evident than the patents of its competitors.

However, an analysis of Google's worldwide patent portfolio shows the search giant's filings include not only cell-phone tech with its gPhone, but also video games and TV.

Google which has already purchased an in-game ad company, AdScape and YouTube, has been pushing Google Checkout, in addition to mobile ads and assorted mobile services.
