2 pending office actions • 1 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready

Analysis

Coval Biopharma (Shanghai) Co. Ltd. currently manages 2 pending office actions within the Biotechnology & Pharmaceuticals technology area. Both of these matters are concentrated within 1 distinct art unit, which indicates a very narrow and specific technical focus for the company's current patent filings. This concentration in 1 distinct art unit can be advantageous, as it allows the company to develop a deep understanding of the specific examination trends and prior art preferences of that particular unit. The 2 pending office actions represent a focused effort to secure intellectual property in the Biotechnology & Pharmaceuticals sector.

The prosecution of these cases is handled by 2 distinct examiners, creating a scenario where each examiner is responsible for a single application. SHIAO, YIH-HORNG is the busiest examiner for the portfolio, currently managing 1 pending office action. With 2 distinct examiners covering the 2 pending office actions, the company receives feedback from multiple sources despite the technical concentration in 1 distinct art unit. This distribution means that the company's success will depend on the individual discretion of 2 different patent office employees within the same technical field.
