Patent common sense

Generally, it will take 2-3 years, and will reply according to the objection in the examiner's notice of review opinions. In addition, before filing a patent application, we must carefully consider every word in the patent claim, strive to accurately express every true meaning, and at the same time pay full attention to the embodiment. The claims mentioned in the application can only be explained in a very limited way in the reply to the notice of examination opinions, so the contents mentioned in the application will directly determine the claims in the final patent certificate.
