Will patent rights hinder innovation to some extent?

Whether the patent system hinders or encourages innovation has always been controversial, especially in many countries where patent abuse exists. Many patent rogue companies rely on patent litigation strategy to make huge profits without actually producing any products, which will certainly hurt the innovation subject and hinder competition.

Historically, Germany and the Netherlands have "anti-patent" movements. 1869 The Netherlands abolished the patent law, and Switzerland vetoed the patent law many times. Britain considered weakening patent protection, and France did weaken patent protection during the Great Revolution. However, the Great Depression of 65438+ 1970 revived patent protectionism, and the "anti-patent" movement basically ended.
