audit program
Countries have different requirements for the examination of patent applications, and basically implement two different systems. Some countries implement the formal examination system, that is, only examine whether the form of patent application meets the legal requirements, but not whether the invention meets the substantive conditions such as novelty.
Some countries implement substantive examination system, that is, not only the form of application is examined, but also whether the invention has the conditions of novelty, creativity and practicality. Only inventions with the above patent conditions can be granted a patent right. China and most countries in the world adopt the substantive examination system.
Duration of protection
The patent law of our country stipulates that the term of invention patent right is 20 years, and the term of utility model and design patent right is 10 years, all of which are counted from the date of application.
