mrloupcity: I think also by changing the name. Sites can legally avoid the lawsuits.

I know prescription drug companies.. when they first come out with a drug.. such as Tylenol.. it was not allowed to be copied for like 20 years.. then after that time.. other drug manufacturers are allowed to create the generic.. Or something like that.. it has something to do with the manufacturer and the brand name..

Anyway.. back to my point.. I think that is how it is with most patents.. and BattleShip has been around for much longer than 20 years..

Different patents though could have different time frames.. so don't quote me.. just finished doing my homework and it is 3am.. so mind is a bit fuzzy.. besides, my one text book about the prescription drugs and patents.. is down at my parents motel .. hehe.. my mom wanted to read through it..
