What are the defects of patent protection?

For scientific research achievements, enterprises should choose patent protection or trade secret protection according to different situations. So, what are the defects of patent protection? Next, Bajie Intellectual Property takes you to know the relevant knowledge. The defect of patent protection is 1. Patent protection is limited, and inventions include three categories, namely inventions, utility models and designs. Among them, the protection period of invention patent right is 20 years, and the protection period of utility model patent right and design patent right is 10 year. This shows that once an invention is patented, it can only be protected by law for 20 years at most. Beyond this period, the inventions and technological innovations of enterprises will be placed in the public domain and contributed to the society for free, and any enterprise can use these inventions or technological innovations for free. 2. Patent protection destroys confidentiality. Because applying for a patent must make the invention and creation of the enterprise public, so that the technology can become a well-known technology, so that anyone can easily obtain the patented technology. Therefore, the openness of patented technology undoubtedly provides realistic conditions for illegal enterprises to infringe patent rights. 3. Patent protection will make enterprises lose their competitiveness. After the scientific research achievements are patented, other enterprises can develop new inventions and obtain new patents on the basis of patented technology. Although the patent of an enterprise is still protected by law, it is already at a disadvantage compared with the updated technology, and the enterprise will lose its competitiveness. Patent protection comes at a price. You have to pay a certain fee to apply for a patent, and you have to pay an annual fee after obtaining a patent.
