Akhan Semiconductor Inc. has 3 pending office actions in the Medical Devices & Mechanical Engineering technology area. These are spread across 3 distinct examiners and 3 distinct art units. This distribution shows that each of the 3 pending office actions is being handled by a different individual in a different art unit, which can lead to varied prosecution experiences. For practitioners, the involvement of 3 distinct art units means that the company's technology is being evaluated under three different sets of technical standards.
LEUNG, CHRISTINA Y is the busiest examiner, with 1 pending office action. While LEUNG, CHRISTINA Y is the busiest, they only handle 1 of the 3 pending office actions. The presence of 3 distinct art units suggests that the Medical Devices & Mechanical Engineering innovations are technically diverse. Practitioners should treat each of the 3 pending office actions as a completely independent legal effort, as the 3 distinct art units will likely apply different examination standards. The outcome for each case will depend on the specific interaction with each of the 3 distinct examiners, including LEUNG, CHRISTINA Y.
