Hangzhou Sanhua Research Institute Co. Ltd. has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are split between 2 distinct examiners. Both examiners are located within 1 distinct art unit.
Kun Kai Ma is the busiest examiner for this portfolio, with 1 pending office action. This 1 pending office action is one of the 2 total pending actions for the company. The use of 1 distinct art unit for both pending actions indicates a singular technical classification for these mechanical engineering projects. Practitioners should note the level of examiner consistency, as the 2 distinct examiners match the count of 2 pending actions. The concentration within 1 distinct art unit further implies that the prosecution strategy can be specialized to the specific standards of that unit. This distribution ensures that each of the 2 distinct examiners is responsible for a single pending matter within the same technical group.
