For businesses listed on a stock exchange, if they successfully get a patent on something, it can really help their stock values go up sometimes. Certainly that does not mean that every time a company receives a patent their stock will rise. It depends on what is being patented, the position it will provide to that company in the market they are in, and several other factors.

But for some businesses it can be vitally important to get a patent on key products. This will help them to ensure that their stock owners will have some faith that the company they invested in will have a product they believe in on the market that is like no other. A recent example might be how a drug company just announced they have patents on 3 new drugs. Once these drugs undergo government approvals like the FDA, this can also tend sometimes to provide the stock with a value lift.

So the next time a company you invested in releases news that they have gotten a patent on one of their products, even though the stock may or may not rise, it can certainly still be a positive thing to see that company compete in their market and push for new ways to do business.
