They need to nullify all those patents, imo. Otherwise, I could get a patent on simple logic.
Someone could theoretically patent the process of trading stocks and then demand a royalty on every profit made on wall street. Right?
What if I patented the practice of calling ahead to book a motel room and then demanded a royalty on every room reservation in every motel in the country?
What if I patented the food pyramid and then demanded a royalty from everyone that ate healthy?
What if I patented the technique of lacing up shoes and then demanded a royalty on every shoe lace made from now till doomsday?
What if I patented the curve ball or the hail mary and demanded royalties everytime these techniques were used?
No, because they have to prove that the patent is "non-obvious", and you also have to deal with "prior art", meaning the "invention" has not already been invented.
