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
