First of all, patents can be discussed under the framework of intellectual property rights, and the standards and definitions are clear. Patent analysis can be better extended to other intellectual property related issues.
Secondly, the issue of patent is important enough, and the output value involved in patent is very huge. In the semiconductor, pharmaceutical, biological and other industries, how to obtain and protect patents is an important part of the work of research institutions such as universities and enterprises.
Finally, the literature on patents is particularly rich, and there are many discussions in the fields of law and economics, and the methods are also diverse, which is especially beneficial for us to compare and discuss. This new answer will not change the previous conclusion: there are no definite advantages and disadvantages of intellectual property rights, and there are no definite rules. In different countries, different development periods and different industries, governments, enterprises and the public will have different interests and expectations for intellectual property rights, and the final result will inevitably be a compromise of interests of all parties.
In fact, in the process of patent system diffusion, there have been repetitions. There has been an "anti-patent" movement in Germany and Holland. 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, in the 19 Great Depression in the 1970s, patent protectionism revived and the "anti-patent" movement basically ended.
In China, in the early 1980s, when the patent law was drafted and submitted to the State Council for deliberation, there were great differences in all aspects, not only department leaders, but also some experts and scholars who had applied for patents abroad and even influential people.
Now, historically, all countries in the world are in the "patent-oriented era" initiated by the United States. However, with the frequent patent lawsuits such as Apple's Samsung War and patent hooliganism, some people think that the patent system originally used to encourage innovation and promote progress has become a tool to crack down, stop, frame up and vilify competitors, thus thinking that patents have been abused and the patent system has hindered the development of innovation.
Admittedly, the patent system still needs to be improved, but there is no doubt that it has played a role in promoting innovation and will continue to promote more active innovation activities.
