Lignosol Ip Limited has 2 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 2 distinct examiners and 2 distinct art units. This means each pending action is being handled by a different person in a different administrative unit. The parity between 2 pending office actions, 2 distinct examiners, and 2 distinct art units represents a completely decentralized prosecution profile.
BUSHEY, CHARLES S is the busiest examiner, with 1 pending office action. With 2 pending office actions and 2 distinct examiners, the company must manage two separate prosecution strategies. The use of 2 distinct art units further suggests that the company's chemistry-related technology is being evaluated under different sets of specialized criteria. This fragmentation requires the company to tailor its approach for each of the 2 distinct examiners currently reviewing its applications.
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.
