Two years ago, when Los Angeles Magazine themed its February special issue the "Hidden LA" issue, W. Lynn Garrett wasn't amused. She is the founder of the astoundingly popular Facebook page called Hidden LA, and she accused the magazine of ignoring her work while trying to lure her community to the magazine. This February, when it happened again, Garrett filed a trademark infringement lawsuit. The suit was filed Wednesday in federal court against Emmis Publishing, which owns Los Angeles. The case was assigned to Judge Mariana R. Pfaelzer.
