Technical depth your litigation team can put to work
GDF brings decades of hands-on technology and expert-witness experience to counsel handling New York matters. Our experts examine the systems behind the evidence and explain their findings in reports, exhibits and testimony that judges and juries can follow.
A dispute may connect a software feature to a database entry, an email to a mobile message, or a device event to a network record. We follow those connections across technical disciplines and work with your team to turn them into a clear explanation of the facts.
Joseph Caruso brings experience in databases, source code, mobile networks and technology disputes. Veronica Perez's work includes mobile-device acquisition, location evidence and forensic instruction. Robert Knudsen brings computer and mobile examination, evidence handling and testimony experience.

Experience illustrated by the evidence
In COMLAB v. Kal Tire, the authenticity of emails and invoices became a central issue in the Southern District of New York. Joseph Caruso examined the metadata and technical explanation offered for missing native email, then explained his findings at an evidentiary hearing. The court credited his testimony, dismissed the action with prejudice and awarded reasonable fees and costs to Kal Tire.
In Rogers v. BNSF Railway, GDF served as database, data-analysis and digital forensics experts for plaintiffs' counsel in a BIPA class action. The work connected biometric-system records to system operation and explainable trial evidence. The litigation ultimately resolved through a $75 million class settlement. The linked case history explains the earlier verdict and subsequent proceedings.
Software disputes: connect the code to the claim
Was software copied? When did a feature appear? Who had access to the disputed material? These are examples of questions we help counsel answer. GDF examines source code, repositories, development history and access records, then relates the technical findings to the issues counsel identifies in patent, trademark and trade-secret matters.
The useful result is an explanation of the relevant functionality, similarities, differences and sequence of events, with supporting material your team can use in reports, deposition preparation and testimony.
Embedded systems: explain what the device did
A device's behavior can depend on firmware, hardware, sensor inputs and configuration working together. For a disputed event, GDF can examine the available device records and technical materials, reconstruct the sequence and explain how those components affected the recorded behavior.
For example, counsel may need to distinguish a software instruction from a sensor reading or determine how a configuration change affected operation. We connect the technical examination to a report and explanation the audience can follow.
From the first technical question to testimony
Bring us the issue, the available records and your next deadline. We help identify useful evidence and focus the examination. Expert reports, declarations, affidavits, timelines and demonstratives explain the findings and their supporting records.
For opposing-expert review, we examine the underlying evidence, methods and conclusions, reproduce relevant analysis and identify the technical disagreements that matter. Counsel receives focused findings for rebuttal and deposition preparation.
Our experts prepare with counsel and provide deposition, hearing and trial testimony. Documented collection, chain of custody and examination methods support a clear explanation of how each opinion was reached.
