Technology area: Chemistry & Materials
2 pending office actions • 2 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready
Anglo Corporate Services South Africa (Pty) Ltd. currently manages a patent portfolio in the Chemistry & Materials technology area, featuring 2 pending office actions. These actions are distributed across 2 distinct examiners, indicating a balanced workload for the company's active patent applications. This arrangement suggests that the company is pursuing multiple technological paths within the chemical sector, each subject to independent review by different examiners.
The prosecution is occurring across 2 distinct art units, which indicates that the 2 pending office actions involve different technical classifications within Chemistry & Materials. PULLEN, NIKOLAS TAKUYA is the busiest examiner for the portfolio, currently responsible for 1 pending office action. Since the total number of pending office actions is 2, the workload is split between the 2 distinct examiners, with no 1 examiner dominating the prosecution process.
Practitioners should note that the involvement of 2 distinct art units and 2 distinct examiners requires a flexible approach to patent prosecution. The success of the Chemistry & Materials portfolio is not tied to a single individual, as PULLEN, NIKOLAS TAKUYA only manages 1 pending office action. This distribution provides a level of variety in the feedback the company receives from the patent office across its 2 active matters.
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.
