Dana Canada Corporation is managing 3 pending office actions within the Chemistry & Materials technology area. These matters are distributed across 3 distinct examiners and 3 distinct art units, reflecting a range of materials-related technologies currently under review. This distribution ensures that the company's prosecution progress is not tied to the decisions of a specific examiner. Engaging with 3 distinct art units allows the company to protect its innovations across several technical classifications.
The busiest examiner, EFYMOW, JESSE JAMES, is responsible for 1 pending office action. This indicates that the pending office actions are split among the examiners involved. For the company, this balanced workload across multiple examiners suggests a stable prosecution environment where individual examiner tendencies are spread across the active portfolio. Practitioners should monitor the 1 pending office action under each examiner to ensure a consistent approach to the company's materials-based intellectual property.
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.
