Patents
hooande: Patents cost a LOT of money to enforce. The odds of you being sued are very low. People will be able to issue you a cease and desist order on the cheap, but the odds of it ever going before a judge are equally low. Business methods patents are notoriously hard to enforce as well.Many big companies collect patents to have as assets. They rarely actually enforce them because it costs too much money (even for them). While your product might dance around infringing on this patent or that, the odds of anyone actually doing anything against you are very low.
