Apple also argued that Amazon's latest move shows it could easily use a non-infringing name for its Android Appstore if it wanted.
"Moreover, Amazon's recent launch of its 'Mac Software Downloads' service -- which competes with Apple's APP STORE software and service for Mac computers -- demonstrates that Amazon can brand its application download services without using the APP STORE mark," Apple said.
Amazon debuted a Mac-specific application download center two weeks ago. Numerous news reports, including one from Computerworld, noted that Amazon had not used "app store" or "appstore" in the name of the center, perhaps because of the ongoing legal battle.
Apple faces resistance to its App Store mark in both the U.S. and in Europe.
In January, Microsoft asked the U.S. Patent and Trademark Office to deny Apple's application, arguing that because the term is generic, competitors should be able to use it.
Last month, Microsoft, its new partner Nokia, Sony Ericsson and HTC joined forces in an attempt to invalidate Apple's trademark in Europe.
