Kangstem Biotech Co. Ltd. has 3 pending office actions in Biotechnology & Pharmaceuticals. The matters involve 3 examiners and 3 art units, indicating three separate examination routes.
BARRON, SEAN C is the busiest examiner, with 1 pending matter. The docket has no examiner concentration in the reported data, so counsel should evaluate each matter independently before treating any technical or claim issue as portfolio-wide.
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.
