Zynga is going after hookup app Bang With Friends, suing its maker with trademark infringement over its use of the phrase "with friends" — common to a series of Zynga games including Words With Friends and Chess With Friends. Bloomberg reports that the company is asking for the court to stop the app’s maker from using the mark as well as pay unspecified damages. In the complaint, Zynga asserts that Bang With Friends "selected the name… with Zynga’s game trademarks fully in mind." Representatives for Bang With Friends have yet to respond about the case.
