If everyone could do it, it wouldn't be as big a deal - small western businesses would be on a more level playing field, since they would be almost as immune from being sued by big businesses as Chinese businesses are. As it is, small businesses aren't protected by patents (because a patent is a $10k+ ticket to a $100k+ lawsuit against a competitor with a $1M+ budget for lawyers) while still being bound by the restrictions of big business's patents. It's lose/lose.
