The term "Jalapeño Poppers" was initially used as a trademark by Anchor Food Products of Appleton, Wisconsin for their brand of cheese-stuffed jalapeños. The Poppers brand has since been expanded to include a line of frozen appetizers — mozzarella sticks, breaded mushrooms, and the like.
On April 30, 1992, Anchor Food Products applied for and later received a trademark on "Jalapeno Poppers"; however, the word "Poppers" had been trademarked in 1983 by the Poppers Supply Company of Portland, Oregon, for use with popcorn. On September 27, 1993, the Poppers Supply Company successfully applied for a trademark on "Poppers" when used for "coated and breaded vegetable pieces", which they held until the trademark was transferred to Anchor Food Products on September 12, 2001.
On September 25, 2001, H.J. Heinz announced that it had completed the acquisition of the Poppers brand; however, a third party, McCain Foods, acquired Anchor's production facilities.
