This is definitely not possible. After submission by the national high-tech enterprise, there will be an expert review stage, which will probably last one to two months. You need to ensure that all your patents are valid from expert review to national filing. Because when searching for your patent at any stage, if your patent has expired, it may lead to insufficient patents or insufficient supporting materials for your R&D project. This will not only cause you to lose points in patents, but also cause you to lose corresponding points in other aspects: such as R&D projects, transformation of scientific research results, etc. Therefore, I suggest that when companies apply for high-tech enterprises, they must check whether some of your patents have been paid and whether they are still valid; and make sure that they are valid within a few months of getting the high-tech enterprise certificate. If you obtain a high-tech enterprise certificate and the patent expires within three years of the existence of the high-tech enterprise, it will have no impact on your application for a high-tech enterprise.
