Pt Spe Subco LLC currently manages 1 pending office action in the Chemistry & Materials technology area. This action is being reviewed by 1 distinct examiner, KHAN, TAHSEEN, in 1 distinct art unit. KHAN, TAHSEEN is identified as the busiest examiner with 1 pending office action, which accounts for the whole of the company's current pending activity. The presence of only 1 distinct art unit indicates that the company's current patent efforts are confined to a specific chemical or material science niche.
Practitioners should note that with 1 distinct examiner handling the only pending case, the prosecution strategy is entirely dependent on the individual tendencies of KHAN, TAHSEEN. There is no diversification across different examiners or art units, making the outcome of this 1 pending office action the sole focus of the company's current patent office interactions. The relationship between the examiner and the 1 pending office action means that any progress made is specific to this single matter. For a practitioner, this requires a highly targeted approach to the Chemistry & Materials technology area, focusing on the specific technical requirements of the 1 distinct art unit and the procedural preferences of KHAN, TAHSEEN.
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.
