legal

Is it legal to call a app 'System 1.0' through to '11.0' or are they trademarks?

That's the best name you got?

Well, have system 1,2,3,4,5,6,7,8,9,10,11,12 been trademarked, by whoi=aand for what puporse? I'm writing a article on software interface and what are good program names.

Well, from a marketing perspective, System 1.0 is not that good a brand name. Its very generic.
