Doing some research on this matter has provided me that the 20 year patent expires on 2 September 2017!
This means we have to wait ONE (1) more year and we can all use the TERM "Tap"!

I, for one, CAN'T WAIT!!! LOL :P
Crystal Heroes will use "Tapping" as the mechanic to exhaust an ability on the card! And there's nothing they can do about it... :P All you get is 20 years!
Joke: I'm going to create a TGC game called "The TAP Game"! :P "Where you TAP cards!!!"
I was just wondering if I am the only one who is glad we will all be able to use the term "tap" in the very near future! :D
I could use the term "exhaust" - but I honestly feel like using Abilities lends better towards "Tap-ping" Abilities (like "Tap into")...
Cheers.
