A123 Systems LLC currently manages 2 pending office actions within the Chemistry & Materials technology area. This portfolio is distributed across 2 distinct examiners and 2 distinct art units, indicating a spread of intellectual property across different specialized groups at the patent office. The workload is evenly split among the assigned staff, as the busiest examiner, KOPEC, MARK T, is responsible for 1 pending office action.
The presence of 2 distinct art units suggests that the company's innovations in Chemistry & Materials may touch upon different sub-sectors or applications. With only 2 pending office actions in total, the prosecution pipeline appears focused. Practitioners should note that the 1 pending office action assigned to KOPEC, MARK T makes this examiner a central figure in the company's immediate patent strategy. The alignment of 2 distinct examiners for these filings reflects a distributed oversight model for this specific set of filings.
Based on the USPTO statutory response window for each pending office action. 2 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.
