IP Infringement Analysis
Generates an element-by-element infringement memorandum covering rights identification, type-specific analysis, defenses, and remedies quantification.
Prerequisites
- IP registrations/filings — patents (with claims), trademark registrations, copyright registrations, or trade secret identification documents
- Accused instrumentality — product specs, screenshots, source code, marketing materials, or service descriptions
- Prosecution history (patents) — file wrapper, claim amendments, examiner rejections
- Relevant agreements — licenses, NDAs, employment/non-compete agreements, assignments
- Correspondence — cease-and-desist letters, licensing negotiations, admissions
- Jurisdiction and procedural posture — forum, statute of limitations status
If any prerequisite is missing, pause and ask — do not assume or fill gaps.
Quick Start
- Identify the IP right(s) at issue (Step 1)
- Characterize the accused activity (Step 2)
- Apply the type-specific framework: Patent (A), Trademark (B), Copyright (C), or Trade Secret (D) (Step 3)
- Assess defenses and vulnerabilities (Step 4)
- Evaluate available remedies (Step 5)
- State overall assessment with confidence level (Step 6)
Analyze each IP type separately when multiple types are at issue.
