I applied for a patent. Can anyone else do it?

Just because you applied for a patent for roast chicken eggs doesn't mean that your patent can be authorized. If you can't do it, of course others can. If the patent you apply for is authorized, it depends on what patent you apply for. If it is a patent for the method of roasting eggs, it is certainly no problem for others to roast eggs in other ways different from yours. What the patent wants to protect is your patent application documents and the technical scheme protected by the claims. Although the state is anti-monopoly, patents are an exception. This is an incentive policy to promote technological progress. However, in order to obtain monopoly patented technology, the premise is to apply to the State Information Bureau in advance and get approval, and pay the annual patent fee every year. At the same time, the patent system is also to protect the patentee who has invested a lot of energy in research and development, otherwise there will be too many things of counterfeiting and stealing technical secrets. Another point is that patent protection has a certain period of time. For example, the invention patent is protected for up to 20 years, which means that the invention patent is protected for up to 20 years. After 20 years, anyone can use your patented technology for free.
