A standard-essential patent is usually anticipated by the very proposals that built the standard — technical contributions filed to the working group before the patent’s priority date, and routinely missed by conventional patent and literature search. SEP Defend searches that contribution corpus first, then the standards and the patent literature, and assembles §102 anticipation and §103 obviousness element by element.
Databases index patents and papers. They do not index the tens of thousands of dated working-group contributions that record the state of the art as a standard was written.
That contribution corpus, searched in full and gated to before the priority date — the single most likely place to find an anticipating disclosure for a standard-essential claim.
Not a relevance list. An element-by-element mapping with a verbatim passage behind every verdict, and combinations flagged by how defensibly they combine.
The differentiator. Tdocs submitted to 3GPP RAN/SA and the codec groups — where a SEP’s prior art usually is, and where conventional search does not look.
The spec text and its earlier versions and releases — one coherent, dated system to read the claim against.
Date-gated patents and applications by CPC and keyword, judged on their full claims — not just title and abstract.
