Guill Tool & Engineering Co. Inc. manages 2 pending office actions in the Chemistry & Materials technology area. These 2 actions are split between 2 distinct examiners and 2 distinct art units. NICHOLAS R KRASNOW is the busiest examiner, holding 1 of the pending office actions.
Because each of the 2 pending actions is in a different art unit and with a different examiner, the company faces a fragmented prosecution landscape despite the low volume. This requires the company to address two different sets of examiner preferences and art unit guidelines. The 2 pending actions represent the entirety of the company's current active workload in this technology area. Managing 2 pending actions across 2 art units requires a coordinated effort to ensure that the company's overall patent strategy remains consistent. This decentralized profile for a small portfolio means that the company must manage 2 separate relationships at the patent office simultaneously. This variety in examiners and art units suggests that the company must maintain a flexible prosecution strategy.
Based on the USPTO statutory response window for each pending office action. 1 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.
