Patents are used to protect innovation, such as unique physical device, its design, and how it works. Once something is patented, you can choose who uses it.
However, there are companies that buy patents but do not build anything using them. They own them purely to enforce them, not market or manufacture the patent. This hurts start-ups and other smaller firms because they most likely cannot defend themselves from patent lawsuits from these companies.
We think that in a lawsuit involving patents, the plaintiff must show a real-world example of the patent in use, showing the design and how it works. If they cannot show one, then the lawsuit must be dismissed or the patents must no longer be relevant.
