The Federal Circuit has warned advertisers that falsely labeling products as 'patented' or 'proprietary' may lead to violations of the Lanham Act. This advisory comes amid increasing scrutiny from the Federal Trade Commission (FTC), which has taken action against misleading advertising practices. The FTC, alongside the Maryland Attorney General, accused Lindsay of overcharging consumers by millions through deceptive online pricing and false claims regarding additional charges for financing. Additionally, the FTC is pursuing its first public enforcement case under the Robinson-Patman Act in decades, targeting Southern Glazer's for alleged price discrimination. The agency is also focusing on misleading 'Made in USA' claims, reflecting a bipartisan trend in merger enforcement under different presidential administrations.
