C2PA establishes a technical architecture for recording, binding, signing, recovering and validating information about digital-content provenance. That architecture draws on technologies that developed across distinct patent domains, including digital signatures, hashing, watermarking, fingerprinting, provenance records and platform attestation. Patenti's 2026 assessment examines how publication-specific independent claims are positioned within this architecture rather than treating content authenticity as a single technology landscape. The assessed U.S. portfolio comprises 541 patent publications and 1,642 independent-claim mappings, resolved against a frozen technical corpus spanning C2PA Content Credentials 2.3, Soft Binding 2.2 and Attestation 1.4. The analysis resolves those claims across 45 primary C2PA technical references and examines the distribution of patent activity across the three principal technical families. The report is a standards-resolved technical assessment of patent positioning within C2PA. It is not presented as a census of every patent concerning provenance technologies, nor as a legal determination of essentiality, infringement or licensing obligation.
