Patent Infringement Case Summary
Produces a standalone, structured summary of a patent infringement case for IP enforcement tracking and litigation reference. Assumes U.S. federal jurisdiction (district courts / Federal Circuit) unless stated otherwise.
Prerequisites
Gather before starting:
- Case filings — complaint, answer, counterclaims, key motions
- Patent documents — patents-at-issue with claims; prosecution history if available
- Court orders — claim construction (Markman) rulings, dispositive motions, final judgment
- Outcome documents — verdict, settlement terms (if public), damages reports, injunction orders
Quick Start
Build the summary in section order. Each section maps to one block in the output. Cite court documents by docket number and date; cite patents by number. Tag unverified citations with [VERIFY].
Output Sections
1. Case Caption
Table with: Case Name (Plaintiff v. Defendant), Court/district/division, Case No., Filed date, Judge.
2. Executive Overview
Two to three sentences: core technology dispute, principal relief sought, current status or outcome.
3. Patents-at-Issue
One table per patent: Patent No., Title, Filed/Issued dates, Owner/assignee, Technology (plain-language), Key Claims (numbers + brief element descriptions), Commercial Significance (products, standards, market relevance).
4. Alleged Infringement
- Accused instrumentalities — products, services, or processes
- Infringement type — direct, indirect (induced/contributory), willful, literal, DOE
- Claim mapping — how accused instrumentalities meet asserted claim elements
- Multiple defendants — joint/several theories or customer-suit issues if applicable
5. Procedural History
Chronological table (Date | Event | Significance) covering: complaint, answer/counterclaims, Markman hearing, key discovery rulings, summary judgment, trial, post-trial motions, appeal. Flag rulings that shaped case trajectory.
6. Legal Arguments
Plaintiff's theories:
- Infringement theories and claim construction positions
- Damages model (lost profits / reasonable royalty / both)
- Injunctive relief basis
Defendant's defenses:
- Invalidity (anticipation, obviousness, § 101, indefiniteness)
- Non-infringement / claim construction positions
