Calyxo Inc. is currently managing 4 pending office actions within the Medical Devices & Mechanical Engineering technology area. These matters are handled by 4 distinct examiners, which reflects a one-to-one ratio between pending actions and assigned personnel. The prosecution activity is distributed across 3 distinct art units, indicating some technical overlap among the applications.
KNAUSS, CHRISTIAN D is designated as the busiest examiner for this portfolio, currently overseeing 1 pending office action. Since there are 4 pending office actions and 4 distinct examiners, no single examiner holds a majority of the workload. The 3 distinct art units involved suggest that the company's mechanical and medical device innovations are being reviewed by multiple specialized groups.
Practitioners should note that the 4 pending office actions require coordination across 4 distinct examiners. While the technology area is unified under Medical Devices & Mechanical Engineering, the 3 distinct art units may apply different examination standards. The involvement of KNAUSS, CHRISTIAN D with 1 pending office action is representative of the broader distribution across the 4 distinct examiners.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
