2 pending office actions • 1 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready
Ardelyx Inc. has 1 pending office action currently active. This action is handled by 1 distinct examiner, and the data shows 0 distinct art units for this portfolio. This indicates a very narrow and centralized prosecution profile, with all current activity focused on a single pending application.
SHIAO, REI TSANG is the busiest examiner for the company, overseeing the 1 pending office action. With only one examiner involved and no art units listed, the company's current patent efforts are concentrated on a single official's review. This requires a focused approach to address the specific concerns of this examiner to move the application forward, as there is no diversification across other examiners or units.
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.
