Xcell Biosciences Inc. has 1 pending office action in the Chemistry & Materials technology area. This single action is the only one currently pending for the company. It is assigned to 1 distinct examiner and a single art unit. This lack of distribution means the company's current prosecution is highly concentrated.
HENKEL, DANIELLE B is the busiest examiner for this portfolio. This individual is responsible for the 1 pending office action. Because the entire workload is handled by this one person, the company's success in this technology area depends on a single relationship. There are no other examiners or art units to provide a comparison for the current prosecution strategy.
A practitioner must tailor their approach specifically to HENKEL, DANIELLE B. The 1 pending office action requires a deep understanding of this examiner's specific tendencies. Since the case is in a single art unit, the practitioner should also focus on the specific guidelines of that unit. The absence of other pending cases means there is no opportunity to test different arguments across multiple examiners.
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.
