Colorado Chromatograpy LLC is managing 1 pending office action in the Biotechnology & Pharmaceuticals technology area. The action is under the review of 1 distinct examiner, CHENG, KAREN, in 1 distinct art unit. This single action represents the total pending prosecution activity for the company. This concentration suggests a focused patent portfolio where all active matters are consolidated under a single point of review at the patent office.
The busiest examiner for the portfolio is CHENG, KAREN, who is responsible for 1 pending office action. Because there is only 1 distinct examiner and 1 distinct art unit involved, the prosecution strategy does not require coordination across multiple divisions. The presence of 1 pending office action indicates a prosecution pipeline that is currently limited to a single matter. This allows for a response strategy tailored to the specific requirements of the 1 distinct examiner. Practitioners should note that the company's immediate patent office interactions are limited to this specific examiner and art unit.
