4 pending office actions • 3 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Chart Inc. currently manages 4 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are being reviewed by 4 distinct examiners, which indicates that every pending matter is being handled by a different individual. This ratio between actions and examiners suggests a broad distribution of the company's intellectual property across the patent office's staff, preventing any single examiner from having an outsized influence on the entire pending portfolio.
The prosecution is further spread across 3 distinct art units, meaning that at least two of the 4 distinct examiners are likely working within the same departmental group. The busiest examiner, PETTITT, JOHN F, is currently responsible for 1 busiest examiner pending office action. Because PETTITT, JOHN F holds only 1 of the 4 total actions, the workload is balanced among the 4 distinct examiners. This distribution requires the company to engage with four different examiner styles and 3 distinct art unit environments simultaneously.
The involvement of 4 distinct examiners across 3 distinct art units for only 4 pending office actions reflects a diversified prosecution landscape. Practitioners must be prepared for varied feedback, as the 4 pending office actions are not concentrated under a single reviewer. The presence of PETTITT, JOHN F as the busiest examiner with 1 busiest examiner pending action highlights that no single examiner currently manages more than a portion of the company's active cases in the Medical Devices & Mechanical Engineering sector.
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.
