Apple is reportedly sending notices to developers asking them to remove the world “memory” from the titles of their games, after a copyright claim from German board games company Ravensburger.

Ravensburger claims to hold the trademark for the word in several European countries where it sells a board game of the same name, Gamasutra reports.

Gamasutra says that it has received confirmation of the news from two separate app developers, although neither Ravensburger nor Apple has responded. Developers are apparently being asked to remove their games then re-submit them under a new name.
