There is a huge difference between "some protection" and blocking the competition for many decades, because an incompetent patent office has approved many exaggerated claims, either about things that are obvious and well known by anyone in the field, but nobody was shameless enough to claim them in a patent before, or else about things that the patent filer is completely unable to do in the present, but they are claimed in the patent for the case when someone else will figure how to do them in the future.

Today the vast majority of patents are not intended for any kind of licensing and they might be even completely useless if licensed, but they are only intended for preventing competition in the market where the patent owner is active.

In order to be useful, a patent system should start to require again that the inventor shows a working prototype that demonstrates all the features claimed in the patent. Moreover, the patents should expire much faster, certainly not later than after 10 years from being issued. Perhaps a longer validity could be accepted for patents owned by individual inventors, but in any case not for the patents assigned to the employers of the inventors, as most patents are today. Also, patent owners should offer "Fair, Reasonable and Non-Discriminatory licensing" (FRAND), otherwise the patent should be invalidated.
