In this June 2017 photo, Mandy Speicher and Rebecca Gordon load up an order of Pierogis at the Konefals stand during the Edwardsville Pierogi Festival in Edwardsville, Pa. A suburban Chicago food festival is threatening a trademark infringement lawsuit over a Pennsylvania group's use of the name "Pierogi Festival." Lawyers for Pierogi Fest in Whiting, Indiana, recently sent a letter demanding that the Edwardsville Hometown Committee stop using the name or pay licensing fees.
