According to the provisions of the patent law, the patentee enjoys exclusive rights to his patent and can exclude others from manufacturing, using, selling or importing his patented product without permission. The appended drawings of utility model patents are one of the important materials when applying for patents, which are used to clearly show the information such as the structure, shape and size of the invention. Once the patent is authorized, the patentee has the right to manufacture, use, sell and import the patented product.
