RDKit R-group decomposition tested Risdiplam (PubChem CID 118513932)'s real structure against US9586955B2's claim 1 Markush formula: MEMBER. Real case: F. Hoffmann-La Roche AG v. Natco Pharma Limited -- Delhi HC Division Bench affirmed refusal of interim injunction, 2025-10-10 (case remains active, further appeal possible).

This result does not predict, endorse, or prejudge that active dispute's outcome.
