In their own suit, Motorola says Apple has infringed on 18 of their patents.
Motorola sued Apple in October, just days before Apple sued HTC for patent violations. HTC and Motorola sell the most popular Android smartphones.
At the time, Apple CEO Steve Jobs said: "We can sit by and watch competitors steal our patented inventions, or we can do something about it. We've decided to do something about it."
The patents relate to 3G, GPRS, 802.11 wireless and antenna design, and OS user interfaces.
Since 2009, Apple has been sued 27 times over alleged patent violations.
