This week, the US patent office issued 6,319 patents. Each patent adds a little something new to the human knowledge base. As we cannot list all six thousand, the PatentYogi team has selected the five most interesting patents.
Worldheart corporation, in collaboration with Carnegie Mellon University, has invented a miniature artificial heart that works on the same technology that powers super fast maglev trains.
