Evidence-grade SEP claim charting

Turn patent claims into verified, version-pinned claim charts.

SpecProof maps every element of a patent claim to the exact clause of the standard that practices it — with verbatim quotes checked character-for-character against the source, so no fabricated citation ever reaches a chart. Essentiality, infringement, and invalidity charts, built on 20,000+ indexed 3GPP, IETF, and MPEG specifications.
