To measure the benefits of patent system innovation, we can learn from seven reference standards, namely, whether patent system innovation can adapt to the development of new technologies. If the patent system innovation only pays attention to protecting the interests of technology developers, but does not provide incentives for developers of other technologies, including substitutes, it will be harmful to technological innovation in the long run; Whether the innovation of patent system can stimulate the full disclosure of invention and creation. Because all technological innovations that meet the conditions of patent protection should be original, which is difficult for ordinary technicians to do. If technological innovation is not fully disclosed, it will not promote the accumulation of total social knowledge; Whether patent system innovation can promote the timely dissemination of technical information. The dissemination of technical information is another important function of the patent system. If the information is not made public, it will not be disseminated. If the information disclosure is incomplete and insufficient, then the information disseminated cannot be complete and sufficient; Whether the innovation of patent system can promote the efficient and orderly operation of patent system and whether the patent authorization is highly stable. Whether the internal operation of the patent system is efficient and orderly is an important factor to ensure the stability of patent authorization. If patents authorized by the patent office are often found invalid in infringement lawsuits, it will inevitably affect investors' confidence in investing in the production of patented products in the future. Similarly, if the cost of applying for a patent or filing a patent lawsuit is high, investors will hesitate to make relevant investments; How easy it is for the public to obtain the right to use patented technology. The scientific research of mankind is based on the research of predecessors, and every innovation of future generations is based on the innovation and application of predecessors' technology. Therefore, when a country innovates the patent system, it is very important to consider how to ensure that the public can easily obtain the right to use patented technology. For those countries whose production and export of technical products play a major role in the national economy, seeking coordination with other countries through patent system innovation plays a particularly important role in promoting product export trade. At present, how to coordinate the patent systems of the United States, the European Union and Japan to save transaction costs has become a very important research topic. We can create a level playing field through the innovation of the patent system, and ensure that all patentees can enjoy the same rights and undertake the same obligations.
