IP Litigation Deposition Supplement

IP Litigation Deposition Supplement

Adds IP-specific examination frameworks to @deposition-preparation. Covers four case types — patent, trademark, copyright, trade secret — with witness-specific question lines and damages theory.

Prerequisites

• Relevant patents, registrations, or trade secret identification statements
• Prosecution history and claim construction positions (patent)
• Prior art references at issue
• Accused product/​process technical documentation
• Licensing history and comparable licenses
• Expert reports (if designated)
• Confidentiality agreements (trade secret)

Case Type Reference

Patent Examination Frameworks

Inventor

• Conception/​reduction to practice: When conceived, what problem solved, corroborating records, who was told, prototyping/​testing timeline
• Prior art knowledge: Awareness at time of invention, searches conducted, how invention differs from specific references — failure to disclose bears on inequitable conduct
• Claims/​prosecution: Understanding of claim 1, meaning of disputed terms, involvement in prosecution, reasons for amendments

Accused Infringer Technical Witness

• Product/​process: How accused product works step-by-step, development timeline and team
• Design choices: Alternatives considered, reasons for chosen approach, awareness of patent, design-around efforts
• Claim element mapping: Whether product has each claim element, how it performs each function
• Non-infringement: Which limitation is missing, how product differs from claims

Licensing / Damages Witness

• Licensing history: Prior licenses (parties, terms, royalty rates), negotiation process, comparable licenses
• Georgia-Pacific hypothetical negotiation: Most significant factors, proposed royalty rate and base, non-infringing alternatives and market availability
• Lost profits (Panduit): Manufacturing capacity, market share but-for infringement, patented feature as demand driver, apportionment methodology

Patent Expert Depositions

Apply @deposition-expert-witness framework, then add:

Technical expert: Claim term construction with prosecution history support; element-by-element infringement walkthrough; physical examination and source code review; prior art disclosure analysis; PHOSITA motivation to combine references

Damages expert: Royalty rate and methodology; which Georgia-Pacific factors applied and how; comparable license analysis; royalty base; "but for" world for lost profits; apportionment to patented feature

Trademark Examination Frameworks

Mark Owner

• Creation timeline, selection rationale, first use in commerce with documentation
• Inherent distinctiveness vs. acquired secondary meaning; supporting advertising
• Awareness of defendant's mark, confusion incidents, harm (lost sales, goodwill, costs)

Accused Infringer

• Adoption timeline, decision-maker, whether trademark search was conducted
• Awareness of plaintiff's mark, legal advice received
• Intent to trade on goodwill or cause confusion
• Knowledge of actual confusion incidents (misdirected orders, customer inquiries)

Trade Secret Examination Frameworks

Owner / Developer

• Specific description of trade secret and what makes it secret
• Security measures: physical (locks, access control), electronic (passwords, encryption), contractual (NDAs, employment agreements, need-to-know)
• Value: development investment, independent replication cost
• Misappropriation theory: how defendant acquired/​used it, timeline

Accused Misappropriator

• Relationship with plaintiff, confidentiality agreements signed
• Access to claimed information, how obtained
• Independent development evidence
• Knowledge that information was confidential
• Disclosure to others, relationship between own product and alleged secret

Key Documents

Checklist

• Review all patents, registrations, or trade secret identification statements
• Review prosecution history and claim construction positions (patent)
• Build claim element mapping chart (patent)
• Analyze all prior art at issue (patent/​copyright)
• Understand accused product/​process technical operation
• Review licensing agreements and identify comparables
• Prepare likelihood of confusion factor analysis (trademark)
• Review confidentiality agreements and security measures (trade secret)
• Review expert reports if available
• Prepare damages theory framework for case type

Pitfalls

• Claim construction first (patent): Establish witness's understanding of disputed terms before infringement/​validity questions — inconsistencies become impeachment material
• Pin inventors on prior art: Document what the inventor knew and when; undisclosed known prior art bears on inequitable conduct
• Prosecution history estoppel: Explore amendments limiting claim scope under DOE
• Trade secret specificity: Use deposition to test whether plaintiff identified trade secrets with reasonable particularity
• Willfulness: Establish knowledge of IP rights and steps taken (or not) after learning of them
• Apportionment: Required when patented feature is not entire basis for demand — press experts on methodology
