Preparation Checklist

• Review patents/registrations/trade secret identification
• Review prosecution history and file wrapper (patent)
• Map disputed claim terms and proposed constructions (patent)
• Prepare claim element mapping chart (patent)
• Identify prior art references and gaps (patent/copyright)
• Understand accused product/process technical operation
• Review licensing agreements and comparables
• Prepare likelihood of confusion analysis (trademark — DuPont)
• Review confidentiality agreements and secrecy measures (trade secret)
• Understand damages theory and expert methodology
• Review expert reports — apply @deposition-expert-witness

Pitfalls

• Pin claim constructions before deposing technical witnesses — questions must track operative constructions
• Lock inventors to specific conception/RTP dates with corroborating documents
• Force precise trade secret identification before substantive questions — vague descriptions create indefiniteness defenses
• Prosecution history estoppel: lock infringers into positions foreclosing DOE arguments
• Cover all 15 Georgia-Pacific factors with damages witnesses; gaps invite Daubert challenge
• Willfulness (§ 284): pre-suit patent knowledge required — establish/negate knowledge timeline
• DTSA vs. state UTSA: confirm governing law; definitions and preemption scope vary
• Copyright fair use: explore each of four factors independently with relevant witnesses
