Gudeng Precision Industrial Co., Ltd. has 9 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are spread across 5 distinct art units, reflecting a variety of mechanical engineering interests. The company works with 8 distinct examiners, indicating that most examiners are reviewing only a single application for the firm.
Steven A. Tullia is the busiest examiner for the portfolio with 2 pending office actions. This low number of actions and examiners suggests a small but active prosecution presence. With 8 distinct examiners for only 9 actions, the company must prepare for a unique examination experience for nearly every pending application. The distribution across 5 distinct art units further suggests that the company's technology is being evaluated by several different specialized groups within the patent office.
Based on the USPTO statutory response window for each pending office action. 2 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.
| Bucket | Cases |
|---|---|
| §103 only | 2 (22%) |
| §102 only | 1 (11%) |
| Multi-statute (no §101) | 6 (67%) |
