<h1>QSR nostalgia product raises trademark (Lanham Act §43(a)), advertising, pricing, sweepstakes, influencer disclosure and competition risks; document licenses and terms</h1> A QSR brand launched a nostalgia-themed product tied to an iconic cartoon concept, using themed marketing, giveaways, influencer content, and low pricing to drive traffic and sales. Legal issues to monitor include intellectual property risks if character likenesses or slogans were used without license, trademark dilution, and rights of publicity; compliance with advertising and promotional laws governing contests, sweepstakes and influencer disclosures; consumer protection concerns about pricing and representations; and competition law implications if pricing unduly undercuts rivals. The brand should document licenses, contest terms, influencer contracts and marketing claims to mitigate infringement and regulatory exposure.
