#Google 's Purchase of #Motorola Mobility

Motorola Mobility holds over 24,000 patents and pending patent applications worldwide. In the US market alone, the company holds around 5,000 patents and 1,500 pending patent applications. The bulk of these patents were assigned to Mobility during the split from Motorola. However, the unit has continued to apply-for and obtain patents since the split. Motorola Mobility also owns a number of subsidiary companies that also hold their own patents, such as General Instrument, Inc.
