Covers witness strategies for inventors, accused infringers, licensing witnesses, and experts. Use alongside @deposition-preparation and @deposition-expert-witness when planning IP depositions, drafting outlines, or analyzing witness strategy.

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

CopyrightOwnership, originality, access/copying, substantial similarity, fair useAuthor/creator, access witnesses, similarity expert, damages expert
Trade SecretExistence, reasonable secrecy measures, misappropriation, damagesDeveloper, accused misappropriator, security witnesses, damages expert

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

DocumentFocus Areas
Prosecution fileAmendments, arguments, prior art, rejections
Invention records / lab notebooksConception date, reduction to practice
Prior art referencesWitness knowledge, differences from claims
Licensing agreementsTerms, rates, comparability
Design documentsAlternatives considered, patent awareness
Technical specsElement-by-element product function
Confidentiality / NDA agreementsObligation scope, acknowledgment
Financial recordsSales, profits, damages support

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
