Almost every entrepreneur seeks a distinction. Many of them grab to patents. They are indeed a differential, but it is one of the most bureaucratic and hard differentials to fight for. I've already heard many people giving unreasonable importance to patents.
Some entrepreneurs think the patent is a shield, but it is not. It helps, of course, but doesn´t guarantee success. I work in a company that has three patents of a particular technology, and even so, the work is not easy. Being successful goes far beyond having a patented technology or product.
In a general way, patents take a long time to be confirmed. Even in the US, the process is entirely manual. It is to be expected that this process will delay, whereas thousands of patents are almost all the same.
Furthermore, they are expensive. You will pay a lawyer to support the litigation, which success is not guaranteed. Even more expensive if you get into a lawsuit, fighting over a patent can be an eternal struggle.
As much as this seems to be the worst way, a few companies live for it!
Some companies buy or create any wholesale patent. If any company presents something similar and is successful, they come to justice. It would be as if patents turn into stocks, you buy cheap, expect someone to use and make money, and then they show up with the judicial collection.
This evil stock market, the patents, has already given what to talk here in the United States. Contrary to that, some executives had created a company that "adjusts” patents, which helps to price patents more honestly. This brings a huge benefit to the innovation´s environment, considering that entrepreneurs focus more on business than on processes. Also, patent collaboration has developed to grown better technologies and better products.
