Post-patent infringement and pre-patent infringement

After the patent application date and before the patent application is published (announced), it is not infringement for others to manufacture the same product as the patent application. Because at this stage, the patent applicant only filed a patent application, and the application has not been made public (announced), whether the patent right can be obtained can only be determined after a series of examinations by the patent office. At this time, the patent applicant does not own the property of the patentee, so he has no right to prohibit others from producing the same product as his patent application, nor to bring an infringement lawsuit against others' behavior. At the same time, during this period, the patent application is in the confidential stage, and others do not know that the product has applied for a patent, so before the patent application is made public (published), others will not bear any tort liability for producing the same product.
