Do mechanical patent engineers work by the piece?

Mechanical patent engineers don't work by the piece. The main responsibility of the mechanical patent engineer is to research and develop innovative mechanical technologies and turn them into patent applications. They need to search for patents, write patent application documents, cooperate with lawyers and participate in patent application examination. The achievements of mechanical patent engineers can be measured by the number of patents applied, and factors such as work experience, level and company policies are often considered in salary calculation. Therefore, the work form of mechanical patent engineers is fixed salary, not piecework.
