Does the patent start from the date of filing?

Legal analysis: Yes, the patent protection period starts from the date of application. Patent protection means that after the patent right is granted, the invention shall not be commercially manufactured, used, promised to be sold, sold or imported without the consent of the patentee. After the patent right is infringed, the patentee protects the patent right through negotiation, requesting the patent administration department to intervene or litigation.

Legal basis: Article 24 of the Patent Law of People's Republic of China (PRC). An invention-creation for which a patent is applied shall not lose its novelty if it is under any of the following circumstances within six months before the date of filing: (1) it was first made public for the purpose of public interest in a national emergency or extraordinary circumstances; (2) It was exhibited for the first time at an international exhibition sponsored or recognized by the China Municipal Government; (3) It was first published at a specific academic conference or technical conference; (4) Others disclose the contents of the application without the consent of the applicant.
