Does the promotion certificate of high-tech enterprises just expire in violation of the advertising law?

It's not illegal. As long as the exclusive patent is not emphasized, it is not illegal. Article 12 of the Advertising Law of People's Republic of China (PRC) stipulates that if an advertisement involves a patented product or patented method, the patent number and patent type shall be indicated. Those who have not obtained the patent right shall not lie in advertisements that they have obtained the patent right. It is forbidden to use patent applications that have not been granted patent rights and patents that have been terminated, revoked or invalid for advertising. According to Article 1 of China's Patent Law, the limited term of invention patent is 20 years, and the term of utility model patent and design patent is 10 year. Whether your patent certificate expires or not depends on what kind of patent your patent certificate belongs to. If it expires, the patent expiration relief scheme: 1, after expiration 1 month. If the patentee fails to pay the annual fee within the time limit or fails to pay it in full, there will be a delay period of 1 month. During the extension period, the annual fee will be paid in time, and there is no need to pay extra late fees. 2. 2 to 6 months overdue. Those who fail to pay the annual patent fee for more than 65,438+0 months will receive a notice of payment issued by the patent administration department, which will carefully list all the fees that the patentee should pay, including the annual fee and late payment fee. As for the late payment fee, if the patent fails to pay the annual fee for 2-6 months, it needs to pay 5%, 65,438+00% and 65,438+05% of the annual fee of that year respectively. If the annual fee is not paid for more than 6 months, the patent right will be terminated, but the patentee can still keep his patent right. At this time, the patentee can pay the annual patent fee, 25% late payment fee and 1 000 yuan patent right restoration fee on time within 2 months after receiving the notice, and then submit an application for right restoration. In particular, the patent right has not been restored within 2 months after receiving the notice of termination of the patent right and the relevant fees have not been paid. Under normal circumstances, the patent right is completely terminated and cannot be restored, so it can be used by the whole people. 5. What if the patent right is completely lost? Generally speaking, after the protection period of invention patents, utility model patents and design patents expires, in fact, many of them no longer have the novelty required by patents. In addition, the loss of patent right can only be saved by reapplying for patent. After the patent right is lost, as long as a new or improved technical scheme is added to the original technical scheme, patent protection can be successfully obtained.
