Catalyst Orthoscience Inc. currently has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These matters are distributed across 2 distinct art units, suggesting that each filing covers a different technical niche within the medical device field. The prosecution involves 2 distinct examiners, so each case is being reviewed by a different official. This structure requires a tailored approach for each application, as there is no personnel overlap between the filings. Success in this portfolio depends on understanding the specific tendencies of each assigned official.
The busiest examiner for this portfolio is LE, KHOA TAN, who is overseeing 1 pending office action. This accounts for a portion of the 2 pending office actions in the total portfolio. Because there are 2 distinct examiners and 2 distinct art units for only 2 cases, practitioners must prepare for two completely different examination experiences. This decentralized environment means that the prosecution strategy must be flexible enough to address the varied requirements of LE, KHOA TAN and the other examiner.
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.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
