Six Areas of Expert Witness Support

Domain name disputes rarely fit neatly into one category — a UDRP matter often involves the same ownership-history and DNS-forensics work as an ACPA case. The pages below are organized by the type of question being answered, so you can go directly to the analysis relevant to your matter.

UDRP & Domain Name Disputes UDRP and URS complaint and response support, bad-faith registration and use analysis, and Reverse Domain Name Hijacking review. ACPA Litigation & Cybersquatting Federal Anticybersquatting Consumer Protection Act litigation support, typosquatting investigations, and trademark-confusion analysis. Domain Ownership & Forensic Investigation WHOIS/RDAP history, chain-of-custody reconstruction, registrant attribution, and stolen-domain investigations. Domain Valuation & Damages Analysis Market-context domain valuation and damages analysis for settlement, litigation, and transactional disputes. Domain Recovery & Security Recovery of stolen or hijacked domains, registrar dispute support, and preventative domain security consulting. Technical DNS & Hosting Forensics DNS change history, passive DNS, hosting/IP infrastructure, SSL history, and redirect and traffic-diversion analysis.
How Engagements Work

Reports, Rebuttals, and Testimony

Regardless of the specific area, most engagements follow the same shape: an initial conflict check and scoping conversation, evidence collection and analysis, a draft report for counsel’s review, and a final report supported by deposition and trial testimony as needed. See the full Engagement Process & Fees page for details on what to expect and what to provide at each stage.

Not Sure Which Service Fits Your Matter?

Many matters combine elements of several service areas — a stolen-domain investigation, for example, often requires both ownership forensics and technical DNS analysis. Send a short summary of the dispute and Bill Hartzer will identify which analysis applies and whether the matter is a good fit.
