Carbonfree Chemicals Holdings LLC currently manages 1 pending office action within the Chemistry & Materials technology area. This workload is assigned to 1 distinct examiner working within 1 distinct art unit. The concentration of the portfolio in a single art unit suggests a highly specialized focus for the current prosecution cycle. This lack of distribution means that the company's immediate patent strategy is tied to a very specific technical niche.
SHENG HAN DAVIS is identified as the busiest examiner for this company, currently handling 1 busiest examiner pending office action. Because the total number of pending office actions is 1, this examiner is responsible for the entirety of the company's active workload at the patent office. Practitioners should note that the prosecution strategy is currently centralized under this single individual. The outcome for the company depends on navigating the specific requirements of this examiner.
The presence of the distinct examiner and art unit indicates that the company's current interactions with the USPTO are limited in scope. This narrow distribution allows for a focused approach to addressing the pending matters. Understanding the specific preferences of SHENG HAN DAVIS is critical for the portfolio. The company must ensure that its responses are tailored to the specific technical standards of the art unit involved.
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.
