Mechanical engineering perhaps has the oldest known inventions and
patents. In fact, the word ‘engineering’ is derived from a mechanical component. Mechanical engineering is a field that was conceived from natural laws of physics, where one engineers or manipulates these laws to his/her advantage.
Mechanical patents non exhaustively and generally encompass utility tools invented constituting force, motion, mass, etc. It specifically encompasses all mechanical devices, contraption and interactions resulting in utilitarian instruments and apparatus, and where such interactions produce a action-reaction component that depends on the mechanism and nature of interaction. Further, all manufacturing processes, for example, metal working and treatment, printing, textile manufacturing, etc, are regarded under mechanical patents. Automobiles fall under mechanical patenting category, although one cannot be sure where a ‘time travel machine’, if invented, will be categorized. Of course, most mechanical engineering fields involve extensive use of computational and mathematical tools, physical laws and equations, but these fall under a different patenting category altogether.
Mechanical inventions have no constraints as they range from a simple yet effective patented invention of a four year old from Texas for “An aid for grasping round knobs” to researched and focused inventions in all areas of mechanical expertise. Few of the well known companies that have a good mechanical patent portfolio include Canon Kabushiki Kaisha with 6798 US patents, General Electric company with 6649 US patents, Xerox Corporation with 2736 US patents and Ford Motor Company, which currently has about 2671 US patents. Some inspiring patented mechanical inventions include legacy devices such as typewriters, Xerox machines to modern inventions such as biomorphic robots, everting heart valves, etc.
