Axcelis Technologies Inc. currently manages 7 pending office actions within the Semiconductors, Circuits & Optics technology area. This workload is distributed across 7 distinct examiners, ensuring that each active matter receives an independent review from a different professional. The prosecution is further spread across 6 distinct art units, indicating that the company's technical filings cover a variety of specialized classifications within the semiconductor sector.
The busiest examiner for this portfolio is KAISER, SYED M, who is currently managing 1 pending office action. This distribution highlights that the company's pending workload is not concentrated under any single individual, as each of the 7 pending office actions is handled by a different examiner. For practitioners, this high level of distribution across examiners and 6 distinct art units suggests a need for a broad prosecution strategy. The lack of examiner overlap means that the outcomes of these matters are likely to be independent, requiring a focused approach to address the specific technical standards and examiner preferences in each case.
Based on the USPTO statutory response window for each pending office action. 4 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 4 of the docket's apps have a known mailing date.
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.
| Bucket | Cases |
|---|---|
| §103 only | 1 (17%) |
| Multi-statute (no §101) | 5 (83%) |
