Legal objectivity:
How long is the duration of patent protection? Applying for a patent means that the protection period of an invention is limited. According to China's patent law, 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. After this period of time, your inventions and technological innovations will be placed in the public domain and contributed to society for free. After applying for a patent, it means that your invention will be made public and anyone can easily obtain your technology. Although it can be protected by law, this protection is strictly limited by legal provisions. In China, a vast country, there are bound to be great obstacles in protecting patent rights nationwide. For example, if you are an enterprise in Heilongjiang and get a patent right, an enterprise in Yunnan infringes your patent right, and the cost of compensating economic losses through law will be great, and enterprises often lose more than they gain. After the invention is announced, many people will develop new inventions based on your technology. Although this marks the progress of social productive forces for the whole society, losses are inevitable for a single enterprise. Because your invention is still protected by law, but it is already at a disadvantage compared with the newer technology, your economic interests will be difficult to guarantee. This is the case at the beginning of the article. It takes a certain fee to apply for a patent right, and an annual fee will be paid after obtaining the patent right. Although these expenses are not high, they can't be squandered by small and medium-sized enterprises. Especially those inventions that have no market value, it is meaningless to spend these time, energy and expenses to obtain the so-called patent right.
