 # Layer A — Office Action Triples for FTO Evaluation
 
 A public dataset of `(invention → cited prior art → outcome)` triples
 extracted from the **USPTO Office Action Research Dataset (OARD)**
-plus per-application metadata enrichment from the **USPTO Open Data
-Portal (ODP)** API. Built as the agent-evaluation substrate for
++ **USPTO Open Data Portal (ODP)** API (US slice) and the **EPO

 [Parallax](https://parallax.3mergen.com), an AI-native Freedom-to-
 Operate (FTO) and defensive-publication platform for individual

 ### Severity enum (`prior_art[].severity`)

+A 3-value severity enum that downstream consumers can join across
+jurisdictions. Each jurisdiction has its own source signal:
 
-| Severity | When set | OARD signal |
+| Severity | US (OARD signal) | EP (WIPO ST.14 search-report category) |
 |---|---|---|
-| `novelty_destroying` | The citation was the basis for a 35 USC §102 anticipation rejection | `rejection_102=1` AND `citation_in_oa=1` |
-| `obviousness` | The citation was the basis for a 35 USC §103 obviousness rejection | `rejection_103=1` AND `citation_in_oa=1` |
-| `background` | Citation listed but not used as rejection grounds (PTO-892 background, PTO-1449 IDS) | otherwise |
+| `novelty_destroying` | `rejection_102=1` AND `citation_in_oa=1` | `X` or `E` (incl. multi-char `XY`, `XYI`) |

+| `background` | otherwise (PTO-892, PTO-1449 IDS) | `A`, `P`, `D`, `T`, `L`, `O`, `I` |

+The EP search-report category sometimes concatenates multiple
+codes (e.g. `"XY"` means the citation is BOTH novelty-relevant AND
+obviousness-relevant). The lowering preserves the raw string and
+the extractor maps the most-severe component to `severity`.

+- **Sample size**: 5 011 rows are a first cut. The full OARD has

 - **Sparse claim text**: The ODP search endpoint returns
   bibliographic metadata (title, applicant, IPC) but not full
   claim text. Some rows have `invention.claims = []` or
   placeholder markers; full claim extraction needs a separate
   ODP call (planned for v1.1).

+  in the citation's bibliographic text annotation (`[Y] 5,12`),
+  not as structured fields. v1.0.2 surfaces an empty
