ESPOO, Finland, July 22 (UPI) -- Rovio, the Finnish maker of the wildly-popular Angry Birds mobile phone game, is being sued by a licensing company for infringing its patents.

Lodsys has filed lawsuits against other big technology companies, including Apple.
It filed an amended complaint with the U.S. District Court for the Eastern District of Texas, naming a number of other big games makers including Atari, EA, and Take-Two Interactive, The Wall Street Journal reported.
Rovio's Angry Birds is available for both Apple's iOS and Google's Android's platform.
