Filtrona Pte. Ltd. currently has 2 pending office actions within the Chemistry & Materials technology area. These actions are assigned to 2 distinct examiners and are located in 2 distinct art units. This distribution indicates that the company's pending matters are being handled by different specialists across separate administrative groups at the patent office.
The busiest examiner for the company is NGUYEN, PHU HOANG, who is responsible for 1 pending office action. This represents 1 of the 2 total pending actions. Because there are 2 distinct examiners for 2 actions, each examiner is managing exactly 1 matter, which prevents the concentration of the pending portfolio under a single individual.
Practitioners should be prepared to manage two separate prosecution tracks, as the 2 distinct art units may have different internal practices. Since NGUYEN, PHU HOANG and the other examiner each hold 1 pending office action, the company must address the specific requirements of 2 different examiners. This spread across 2 distinct art units requires a strategy that accounts for the nuances of each specific technical area within Chemistry & Materials.
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.
