Tech: Microsoft suddenly complains about Apple “App Store” trademark
- then Back in 2008, Apple trademarked the words “App Store” to advertise its silo of third-party programmed application goodness. The U.S. Patent Office opened up the name for opposition in 2009, and Apple later used it for it Mac App Store.
- now Microsoft, trying to gain a foothold with Windows Phone 7, decided to protest use of the name, saying that it was too generic. Note that the U.S. Patent Office has allowed others to protest this trademark for more than a year. source
