You miss read my second post.
Let me respond point by point:
> Ok then when you search sudoku exactly ONE app should appear. The trademarked version or none at all.
Correct - unless my comments (second post) above are correct, or App Review let other apps go through, or the other apps have permission from the trademark holder. But I think my comments above are correct. Reread them.
>But according to your definition then NO ONE should be able to search any 'trademarked' keyword.
Nope, reread what I wrote. I gave you a pathway to use a trademarked term in the search. But if that pathway is not followed, then correct! That's why it's called 'intellectual property'. No one should be allowed to drive my car or use my trademarks.
>Want to play chess.
"chess" is not trademarked. But imagine you made a GREAT app with a NEW game called BazooTa. Everyone was using it. I made a crap app and called it BazoDaDa and used BazooTa as a search term. Would you be upset that all kinds of people looking for your great game found my crap game and decided this whole Bazo craze was a waste of time. That's a little far fetched - but if you want a really good Band Aid don't use an adhesive bandage from CVS. And that law applies.
>everyone will trademark...
You can't trademark every word. You can only trademark a term that was not commonly used and that you now use to commercialize something - that means the only reason it will be a good search term is because of your efforts. You deserve to benefit from those efforts - or better - if you can benefit from such efforts you will put in such efforts to create value. That's why we have trademarks. If you don't like that then cry in a Kleenex brand tissue - they are softer then ordinary tissues - unless someone sells you a different brand when you are 'searching' for Kleenex.
>Ayn Rands philosophy is great in theory
No it's not. It fails to benefit from cooperative efforts. Trademarks and patents and copyrights put into law such cooperative efforts but people, working together, can create trusting relationships that overwhelm any advantage of Ayn Rand philosophy.
