Technology area: Biotechnology & Pharmaceuticals
2 pending office actions • 2 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready
CSL Limited is currently managing 2 pending office actions within the Biotechnology & Pharmaceuticals technology area. These matters are being handled by 2 distinct examiners, which indicates that no single official is responsible for more than one case. This arrangement requires the applicant to adapt to the specific preferences and legal interpretations of two different individuals. The absence of examiner concentration suggests that the prosecution of these 2 pending office actions will proceed along independent tracks.
The company's active cases are distributed across 2 distinct art units, highlighting the technical variety within their biotechnological filings. This spread across multiple art units means that the 2 pending office actions may be subject to different internal guidelines and examination speeds. MERTZ, PREMA MARIA is identified as the busiest examiner for the portfolio, currently managing 1 pending office action. Since this busiest examiner is responsible for 1 of the 2 pending actions, the workload is not concentrated in any single office.
For those managing the CSL Limited portfolio, the use of 2 distinct examiners across 2 distinct art units necessitates a careful review of all correspondence to ensure technical consistency. The fact that MERTZ, PREMA MARIA holds 1 pending action means that the other action is being reviewed by a separate official. This distribution provides a diversified exposure to the patent office's examination corps for the 2 pending office actions currently in progress.
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.
