What is the duration of patent protection? Applying for a patent means that the protection period of an invention and creation 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 2 years, and the period of utility model patent right and design patent right is 1 years. This shows that once an invention is patented, it can only be protected by law for 2 years at most. After this period, your inventions and technological innovations will be placed in the public domain and contributed to the society free of charge. 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 country with a vast territory, there are bound to be great obstacles to the protection of patent rights nationwide. For example, if you are an enterprise in Heilongjiang and get a patent right, and an enterprise in Yunnan infringes your patent right, 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 into new inventions on the basis of 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, and 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 that are penny wise. 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.
