Windows is a not a descriptive term when it relates to computer operating systems. What you are searching for is Windowing System. Operating systems have nothing to do with Windows, the UI element.
We can agree to disagree. I fully remember referring to the Mac OS classic as running a "Windows Operating System" -- I'm pretty sure the term "Windowing Systems" came later to distinguish from Microsoft Windows.
No it's not. A windowing system and a Window UI element is quite different from an operating system. If Apple trademarked Apps to refer to those applications you install on iOS, that would be akin to Microsoft trademarking "Operating System" as the name of their next version of Windows.
Yes, but if Apple used the term "Apps" to as the name of their "App Store" it would be equivalent to using "Windows" to describe a "Windows Operating System". The term "App Store" is more specific than "Apps", but still generic and descriptive.
None of those are descriptive and if you look carefully, most of those are probably trademarks on the respective logos.
Actually, you should look a bit more carefully. The term "logo" follows all those that are logo trademarks. Those that are trademarks on phrases omit the word "logo" (e.g.: "Smile Logo" or "Shopping Cart with Border Logo" are trademarks on logos). My favorite of those is "Procurement Web Services" and "Relational Database Services". But still there are many generic terms.
Finally, use multi-quote next time, consecutive posts are against the forum rules.
Sorry I failed to scroll down before responding -- but I do know the forum rules. If I could merge them after the fact I would have.
I am not arguing that "App Store" is not generic and descriptive. It is. Apple just made it popular. What I am arguing is that the USPTO grants these kind of trademarks all the time even to some of the guys who are challenging it. People complain of Apple trying to go after people for using "App Store" and say that "some folks don't go after others for using their trademarks". The truth of trademark law is that if you do not protect your trademark (or desired pending-trademark) then you lose it. So any failure on Amazon's part to enforce their generic descriptive trademarks could lead to them losing those trademarks.
So before we all go crying that Apple is trying trademark a generic descriptive term, let's look at the fact that their is much precedent for the same thing -- and there should not be. Maybe the madness should stop here, but I'd like to see it stop for everybody.
Finally, however this goes (granted trademark or denied trademark) it won't matter to any of us a week later.
