Meaning
A capital R inside a circle, the registered trademark sign. It indicates that a brand name or logo has been officially registered for protection.
Companies place it after brand names on packaging and ads, and people sometimes add it jokingly to their own catchphrases or family recipes: “Grandma’s Secret Fish Sauce®️, recipe not for sale” Unlike ™️, which anyone can add to a claimed mark, ®️ is meant for marks that are actually registered.
