Authenticating What You Cannot Trust: Synthetic Media and Deepfake Evidence in IP and Patent Disputes

By the end of the webinar, participants should be able to:

· Distinguish authentication from relevance, hearsay, best-evidence, and expert-reliability questions.

· Select a supportable federal or New York authentication route for common digital-media exhibits.

· Use the 2026 New York Court of Appeals decision in Matter of M.S. to recognize foundation and chain-of-custody weaknesses in video evidence.

· Preserve source, capture, metadata, integrity, and transformation information before those facts disappear.

· Explain what a cryptographic hash can establish and what it cannot.

· Use detector output as a technical input without presenting probability as a legal conclusion.

· State the current status of proposed Rule 707 and the Rule 901(c) working draft without treating either as law.

· Build a concise foundation or challenge record for a disputed digital exhibit.
