Demo: PTAB appeal evidence bundle

A complete, signed evidence bundle capturing a PTAB reversal decision: structured metadata, decision PDF, portal captures, provenance, and a replay verifier.

This is not legal advice. It is a demonstration of how PatentChecker packages procedural patent events into forwardable, offline-verifiable artifacts.

Appeal metadata

Appellant: Syngenta Participations AG

Decision outcome: Reversed

Decision date: 2026-04-14

Tech center: 1600

Why this matters

Reversed outcomes in TC 1600 are rare. Packaging the decision into a schema-addressed evidence bundle lets downstream teams track claim-scope and validity dynamics without re-querying portals.
