# Patent Novelty and Non-Obviousness Check Assess patentability of: **$ARGUMENTS** Adapted from `/novelty-check` for patent legal standards. Research novelty is NOT the same as patent novelty. ## Constants - `REVIEWER_MODEL = gpt-5.5` — Model used via Codex MCP for cross-model examiner verification - `NOVELTY_STANDARD = patent` — Always use legal patentability standard, not research contribution standard ## Inputs 1. Invention description from `$ARGUMENTS` 2. `patent/PRIOR_ART_REPORT.md` (output of `/prior-art-search`) 3. `patent/INVENTION_BRIEF.md` if exists ## Shared References Load `../shared-references/patent-writing-principles.md` for novelty/non-obviousness standards. Load `../shared-references/patent-format-us.md` for 102/103 analysis framework. ## Workflow ### Step 1: Define Claim Elements From the invention description, extract the key claim elements that would define the invention's scope: 1. List the technical features that make the invention novel 2. Identify which features are known from prior art vs. inventive 3. Draft preliminary claim language for 2-3 independent claims (method + system) ### Step 2: Anticipation Analysis (Novelty) For each preliminary claim, test against EACH prior art reference in `PRIOR_ART_REPORT.md`: **Single-reference test**: Does any single reference disclose ALL claim elements? | Claim Element | Ref 1 | Ref 2 | Ref 3 | ... | |--------------|-------|-------|-------|-----| | Feature A | Yes/No + evidence | | | | | Feature B...
