Casinos don't patent means of seating you next to poker professionals without your knowledge in order to force you to buy special casino advantages with more money to try and compete.
They don't do that in order to get you to buy overpowered stuff. However I have heard stories where players where hired by the casino to fill up tables and play aggressive in order to create a lot of rake for the casino. And of course the players often would be winning-players due to a more professional approach of the game.
