Because people’s understanding of intellectual property rights is not comprehensive, some technicians believe that as long as they innovate independently, they will have independent intellectual property rights. However, this is not the case. Patents are a kind of monopoly right. If independent research and development of technological achievements are not patented, they will have no legal effect. If others misappropriate their research results, because the researchers do not have patent rights on the results and cannot receive legal protection, the embezzler cannot be held legally responsible. At the same time, in our country, patent applications adopt the first-to-file principle. The patent will be granted to whoever applies for an invention that is creative, novel and practical first. Therefore, if the developer does not apply in time and is preempted by others to apply and be granted a patent, the developer will not be able to pursue the legal liability of others.
