CaseMark Prior Art Summary
Synthesizes prior art references into structured summaries mapping disclosures to claim elements for rapid landscape assessment.
Prerequisites
- Prior art references — patents, applications, publications, product docs, or public disclosures
- Invention description — claims or specification under analysis
- Scope directive — prosecution, validity/invalidity, or FTO
Workflow
1. Executive Overview
Produce a table covering:
- Total references reviewed (count)
- Most material references (top 3-5 with one-line rationale)
- Key gaps (claim elements with no or weak coverage)
- Art type breakdown (patents / applications / publications / other)
2. Individual Reference Summaries
For each reference:
| Field | Content |
|---|---|
| Document ID | Patent/pub number, DOI, or identifier |
| Title | Full title |
| Date | Pub/issue date; note effective prior art date if different |
| Inventor(s)/Author(s) | Names |
| Technical field | CPC/IPC classes or subject domain |
| Assignee/Publisher | Entity |
Then include:
- Disclosure summary — 2-4 sentences on core technical contribution
- Key features — bulleted list with exact quoted language and precise citation (¶, col:line, page, figure)
- Gaps — what the reference does NOT disclose relative to the invention
3. Claim-Element Mapping
| Claim Element | Ref. 1 | Ref. 2 | Ref. 3 |
|---|---|---|---|
| Element A | ¶[0032], Fig. 3 | — | p. 12 |
| Element B | — | Col. 4:15-22 | — |
Legend: ✓ full disclosure, ~ partial, — absent. Always include citation location.
4. Combination Analysis
For each potentially obvious combination:
- References combined — which refs
- Motivation to combine — analogous art rationale, explicit suggestions, design incentives
- Missing elements — what remains undisclosed even in combination
5. Timeline
Chronological list by effective date, noting critical date boundaries (priority, filing, publication dates).
Guardrails
- Cite precisely — every factual assertion needs ¶, col:line, page, or figure number
- No legal conclusions — organize facts for attorney judgment; never state claims are anticipated or obvious
- Analogous art — flag references outside the immediate field with rationale for qualification
- Prior art status — note references whose qualification depends on date analysis (pre-AIA vs. AIA § 102) [VERIFY]
- Foreign-language refs — flag language, provide translated key passages, note if machine-translated
- Figures — describe depicted features with enough detail to be useful without viewing the original
- Terminology — define specialized terms on first use in brackets
- Order by relevance to claim elements; use chronological only if requested or analytically significant
