A report on gaming news site Gamasutra claims that Apple is warning developers of iOS games that German game maker Ravensburger owns the trademark for the word "memory" in association with a game title in 42 countries, and unless they change the app name, it will be removed from the App Store. The company does not own the title in the United States, but it seems that the ban is universal, and will be enforced before the end of the year worldwide, according to sources MacNN spoke to familiar with the matter.
