3 pending office actions • 2 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready
Nanjing Tiannong Biotechnology Co. Ltd. has 3 pending office actions in the Biotechnology & Pharmaceuticals technology area. These matters are assigned to 3 distinct examiners across 2 distinct art units. The distribution across 3 distinct examiners suggests that the workload is not concentrated under one person, allowing for multiple parallel paths toward allowance.
Kyung Sook Chang is the busiest examiner for the company, currently overseeing 1 pending office action. With 2 distinct art units involved, the prosecution is spread across multiple technical groups, which can be beneficial for diversifying the company's patent risk. Each of the pending actions is being handled by a different examiner, ensuring that no single individual's review style dominates the portfolio.
For the company, this structure requires a coordinated strategy that addresses the specific requirements of the assigned art units. While the active actions are in the biotechnology sector, the different examiners may have varied interpretations of the prior art. Managing these distinct examiner relationships effectively is crucial for advancing the company's biotechnology applications toward issuance.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
