According to Mr. Lesko, Topps never previously trademarked the acronym “GPK”, only the term “Garbage Pail Kids” was trademarked. It remains to be seen how Topps will use this trademark going forward. Now that the 30th anniversary set has been released there have been no upcoming announcements for future GPK card sets.
