 If there was no protection for innovators there would be limited incentive for someone to take the risks and create the market for a new product. Apple is recently in the news for a new patent on a watch that has a removable digital camera. It's going to remain to be seen whether there's a market for this and whether they actually launch the product. Whoever comes up with it first and launches first is the company that's taking the biggest risk in this and that's where the usefulness of the patent comes in because the patent will provide a 20-year monopoly on products covered by the claims of the patent. We've all heard that expression. Certainly as patent attorneys sometimes the second mouse gets the cheese because the first one gets their their head snapped. The patent is a way to kind of offset that by providing protection for the first inventor so that if they take the risks and they invest in new technology be the first to bring something to market first to create something that there's some protection so that all the other competitors cannot jump in and enter the field.
