Thomas Broadbent & Sons Limited currently manages 1 pending office action in the Chemistry & Materials technology area. The prosecution of the company's patent applications is focused, involving 1 distinct examiner and 1 distinct art unit. This indicates a singular focus for the company's current efforts to secure patent rights. Such concentration allows for a more predictable interaction with the patent office, as the company only needs to navigate the specific technical interpretations of 1 distinct art unit.
LIU, SHUYI S is the busiest examiner for this portfolio, who is handling 1 busiest examiner pending office action. This single action represents the total of 1 pending office action for the company. All current feedback from the patent office is channeled through this 1 busiest examiner pending office action and the single associated art unit. The concentration of the workload under 1 distinct examiner allows for a more direct dialogue during prosecution, potentially simplifying the process of reaching an agreement on claim scope within the Chemistry & Materials sector.
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.
