Xeltis AG currently manages 3 pending office actions within the Medical Devices & Mechanical Engineering technology area. These 3 actions are distributed among 3 distinct examiners, with each examiner overseeing 1 pending matter. The prosecution involves 2 distinct art units, suggesting that the company's medical device technologies are being evaluated by a narrow set of examination groups.
RASSAVONG, ERIC is the busiest examiner for the portfolio, accounting for 1 pending office action. The presence of 3 distinct examiners for the 3 pending actions indicates a lack of examiner-level concentration. However, the use of 2 distinct art units for these matters shows that the technical focus of the pending applications is relatively consistent across the portfolio. This structure requires the company to maintain consistent arguments across examiners while operating within the 2 technical divisions at the USPTO. The limited number of 2 art units may allow for some synergy in prosecution strategy, even as the company addresses the specific concerns of the 3 examiners.
Based on the USPTO statutory response window for each pending office action. 2 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.
