MCKEE, VOORHEES & SEASE, PLC, Attn: ChampionX LLC has managed 43 career applications in the Transportation, E-Commerce & Mechanical Systems technology area. The firm has a resolved allowance rate of 83.33 percent for this specific client profile. Prosecution requires an average of 6.0 office actions per allowance, suggesting a highly iterative and intensive examination process for these mechanical and e-commerce matters.
There are 4 pending office actions currently active. The 6.0 average office actions per allowance is a notable figure, indicating that securing these allowances involves extensive negotiation or multiple rounds of rejection. Despite this high number of actions, the 83.33 percent allowance rate shows that the firm eventually secures patent rights for the majority of these 43 applications. This persistence is a key characteristic of their work for ChampionX LLC, where the firm navigates a complex examination path to reach a successful outcome for the client.
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.
