Cross-cut index
Each cross-cut file lists every corpus entry carrying the tagged component, in chronological order by first verified public disclosure date. Use these as the working prior art search tool when assessing wearable patent claims.
Three families:
- Single-axis cross-cuts — one file per form-factor / sensor / algorithm tag.
- Intersection cross-cuts — one file per (axis × axis) tag pair with ≥3 entries. These are the direct inputs to OBVIOUSNESS_TEMPLATE.md.
