Chemical portfolios vary—from catalytic routes and polymer formulations to refinery processes—each with distinct examiner mixes and claim strategies. Ranking by allowance rate within C01–C09 and C10C/C10G isolates performance in the chemistry you actually prosecute. It levels the field across firm size and docket mix and focuses on the outcome clients care about: Did the work convert to granted rights in this industry? CPC granularity keeps comparisons apples-to-apples, so a polymer specialist isn’t measured against a refining-heavy docket, and vice versa.
The result: fair, comparable standings you can defend in a partner meeting or an RFP.
Chemical innovation spans synthesis routes, formulations, catalysts, and refining—often overlapping with materials and energy. To keep comparisons fair and apples-to-apples, we anchor this view to CPC subclasses that directly capture chemical compositions and processes. We emphasize C01–C09 (core chemical synthesis and compositions) and C10C/C10G (petroleum/related chemical processes).
Device-heavy or general manufacturing CPCs appear in their own industry views unless claims center on chemical transformation. Energy/clean-tech classes appear here only when the invention’s center of gravity is the chemistry, not systems integration. For multi-industry filings, we classify by the primary CPC and standardized rules documented in the methodology.
