according to the provisions of the patent law, as long as the technical scheme of a new patented product has not been made public before the date of application, and no one else has applied for a patent in advance in the same technical field, patent protection can be obtained. The change of construction sequence will not change the technical scheme of the product, but only adjust its implementation. Therefore, as long as the technical scheme of the new patented product remains original innovation and practicality, even if the structural order changes, the patent is still valid.
