Invention patents are granted for a long time, usually three to five years, but the granted patents are highly stable due to the need for substantive examination procedures; Patents for utility models and designs can be granted quickly without going through substantive examination procedures. The general utility model can be authorized within 6 months to 12 months from the date of application, and the design can be authorized about 6 months from the date of application.
Matters needing attention in patent authorization
Apply in time: Because the novelty and creativity of patent application are related to the filing date, if you apply one day later, the technology will be more likely to be made public by others. Moreover, the patent right is granted to the person who applies first. Therefore, it may be that the application date is only one day later than others, and those who apply late will be subject to the early application for 20 years.
The quality requirement of patent is "no best but better", because as long as someone can overturn your patent, it means you will give up all your efforts. With the progress of society, the social division of labor is becoming more and more detailed, mainly in the technical field. So, don't try to deal with problems that you are not good at.
