Trade secret cases often turn on digital facts: who signed in, what they opened, what they copied, where they sent it, and what happened right before or after a departure, vendor dispute, or suspicious download. In many situations, the difference between a vague suspicion and a provable claim comes down to whether those records were preserved early, carefully, and in a defensible way.
That is especially true when evidence lives in places that change fast: cloud audit trails, endpoint telemetry, browser history, email headers, mobile device records, USB artifacts, collaboration platforms, and short-retention security logs. Once routine deletion, auto-rotation, device replacement, or account shutdown kicks in, key evidence can disappear. Under Federal Rule of Civil Procedure 37(e), courts look at whether electronically stored information that should have been preserved was lost because reasonable preservation steps were not taken. In general terms, that makes early evidence preservation a litigation issue, not just an IT issue.
In this post you’ll learn how companies often preserve access logs, device records, and download evidence in a trade secret case; which data sources tend to matter most; where businesses sometimes lose critical proof; and how an attorney and forensic team may help frame a preservation strategy that fits the facts. If you want broader context on how these cases arise, our overview of employee exits, vendor leaks, and emergency court requests provides the larger trade secret enforcement picture.

A trade secret claim usually involves more than the existence of confidential information. The dispute often centers on access, use, transfer, concealment, and timing. A company may already know that sensitive files existed. The harder question is often whether someone accessed them unusually, downloaded them in bulk, sent them to a personal account, synced them to cloud storage, connected removable media, or wiped traces afterward.
That is one reason federal trade secret practice often intersects with emergency relief. Under the Defend Trade Secrets Act, 18 U.S.C. § 1836, federal courts can issue injunctions, and in extraordinary circumstances may even allow an ex parte seizure process. But the statute sets a high bar: a court may grant ex parte seizure only where specific facts show, among other things, that ordinary Rule 65 relief would be inadequate and that the target would likely evade or ignore a notice-based order. The statute also requires narrow tailoring and protections for seized materials. That structure reflects how sensitive early evidence-preservation requests can become in trade secret cases.
The Federal Judicial Center’s Trade Secret Case Management Judicial Guide notes that courts often deny ex parte seizure requests where a Rule 65 order on notice appears adequate or where preservation concerns are stated in conclusory terms rather than supported by specific evidence. The same guide discusses early requests for record preservation, forensic inspection, and alternatives to seizure. In practical terms, that often means the quality of the preservation record matters from the very beginning.

Access logs usually include records showing sign-ins, authentication attempts, IP addresses, device identifiers, session history, permission changes, and file or application access events. Depending on the environment, they may come from:
