Apple has been trying to vigorously defend the words “App Store” from other third party “App Stores” that have adopted the same name. Last month they took on GetJar, to which Getjar basically told Apple where to go. Amazon hasn’t been so lucky.
US courts denied Apple’s request for an injunction against other app stores while they pursue trademark infringement cases. In Germany though, their courts have imposed a restriction which has resulted in Amazon temporarily suspending submissions from German developers.
The Amazon App Store only allows downloads and purchases from the US however they accept application submissions from around the world.
Apple’s lawyers have been very busy in court with various patent cases and this trademark infringement. Personally we feel that with the way the mobile app ecosystem has changed the words app store are as common place as grocery store and Steve Jobs just needs to get over it
