Interesting story: My brother is an intellectual property attorney, and he knows I'm interested in anything Wackys related. He has done searches for legal cases and decisions regarding Topps and Wackys for me. He saw the same Sonic menu and did some research on the topic. Turns out Sonic registered "Wacky Packs" as a trademark in 1998, and Topps' trademark in the name was cancelled in 2015! Topps needed to file a Declaration of Use to maintain its interest in the name, but it wasn't done. The good news is that "Wacky Packages" (as opposed to "Packs") is still completely protected! Crazy, huh? - Pete
