Last year Apple sued Amazon over the use of their trademark ‘App Store’ and that battle continues to ensue. Most recently, Amazon requested a federal judge to throw out Apple’s false advertising claim against them as they felt the term is generic and commonplace in nature.

Now, according to Patently Apple, that battle has reached Canada with this time Amazon and Nokia opposing the term here, according to recent updates at the Canadian IP Office, as seen in the image below:

The Canadian IP Office indicates that the opposition has until January 13, 2013 to present their evidence as to why Apple’s App Store trademark should be denied.

A former opposition case by Microsoft against Apple’s claim in Canada was recently closed. What do you think? Is ‘App Store’ generic or should it be Apple’s claim only?
