"It's old-fashioned to get a patent and monopolize idea. It's better for the world to share it."
Some people say . However, the fact that companies have obtained a patent has many opportunities to motivate us to adopt an invention.
And if you say "should be shared" because it is such an invention that is worth adopting, "worth adopting," is nothing but "patenting = a new and useful invention".
If there is no patent system, valuable inventions and non-valued inventions (or inventions that are harmful) will be "shared" as one. Is it possible to select and use only inventions that are valuable to the company in such a situation? If you want to share a patented invention, all you have to do is sign a license agreement. The patent system is not only a system for monopolizing an invention to one company / individual, but also a system for evaluating and sharing the value of an invention.
