Notice of Prior Art
Drafts a litigation-ready Notice of Prior Art with element-by-element claim mapping, prior art reference disclosures, and procedural compliance for USPTO, district court, or PTAB proceedings.
Prerequisites
- Patent-at-issue — number, filing/issue dates, inventors, independent + dependent claims
- Prosecution history — IDS filings, office actions, claim-narrowing amendments
- Prior art references — patents, publications, products, public uses with dates and bibliographic data
- Procedural context — forum: USPTO (37 CFR 1.56) | district court (local patent rules) | PTAB (§ 311) | informal
- Claim chart — which claims are challenged and which limitations each reference addresses
Checkpoint A: Pre-Draft Intake
Determine before drafting:
- Pre-AIA vs. AIA — which § 102 framework applies (effective filing date before/after March 16, 2013)
- Forum — dictates caption format, citation conventions, certification language, and evidentiary standard
- Claim construction — adopt consistent terminology matching patent claims and specification
- Scope — anticipation only (§ 102), obviousness (§ 103), or both
Step 1: Header & Caption
| Forum | Required Elements |
|---|
| USPTO | Application/patent number, art unit, examiner, confirmation number, customer number |
| District Court | Full case caption, civil action number, court/division, assigned judge |
| PTAB | Proceeding number (IPR/PGR), patent number, petitioner/patent owner |
Include statutory basis (35 U.S.C. §§ 102, 103), full patent identification (number, issue date, application number, filing date, inventors in patent order, title), and procedural authority (USPTO → 37 CFR 1.56; district court → local patent rules; PTAB → § 311).
Step 2: Prior Art Reference Disclosures
For each reference, provide:
Patent references:
- Full number with country code (e.g., US 5,123,456 A), all inventors, issue/publication date, title, assignee, CPC classification
- Foreign patents: original-language title + English translation; patent family info
Non-patent literature:
