Lyell Immunopharma Inc. currently manages 2 pending office actions. This workload is distributed across 2 distinct examiners and 0 distinct art units. This distribution of actions across the examiners relative to the 2 total actions indicates the level of concentration in the company's prosecution focus. Such a structure suggests that the company's intellectual property is being reviewed by specific administrative paths, which can influence the consistency of feedback from the patent office.
The busiest examiner for this portfolio is CUNNINGCHEN, KATHLEEN MARY, who is responsible for 1 pending office action. This individual handles 1 actions out of the total pending for the company. For practitioners, the involvement of 2 distinct examiners across 0 art units provides a specific map of the current prosecution landscape. This concentration or dispersion of matters requires a tailored approach to examiner interviews and response strategies to ensure that the technical arguments remain effective.
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.
