If it is an invention patent, the rights can be directly protected by the method described in fys888, because the invention patent has passed the formal examination and substantive examination.
However, when applying for a patent for utility model or design, the Patent Office does not conduct substantive examination, that is to say, as long as the application documents meet the requirements, patent certificates can be issued regardless of whether the technology meets the requirements of the Patent Law. This means that although you have obtained a patent certificate, your patented technology does not necessarily meet the requirements of "creativity, novelty and originality" in the patent law. If there is, it is very difficult in the process of safeguarding rights. If necessary, you should ask the patent office to conduct a substantive examination of your patent.
