Celanese Polymers Holding Inc. currently faces 3 pending office actions within the Chemistry & Materials technology area. These actions are being reviewed by 3 distinct examiners, indicating that each action is assigned to a different individual. The portfolio is situated within 2 distinct art units, which suggests technical concentration despite the involvement of multiple examiners. DICUS, TAMRA is the busiest examiner for this company, holding 1 pending office action.
Managing these pending office actions across 2 distinct art units allows the applicant to potentially see thematic overlap in the examination process. However, the use of multiple distinct examiners means that the specific negotiation style for each case will likely differ. The 2 distinct art units involved represent the technical environments where the company is seeking protection. Practitioners should note that the involvement of multiple examiners necessitates a review of each individual's specific history. DICUS, TAMRA serves as a point of contact within this Chemistry & Materials portfolio.
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.
