The right expert. Whatever the field.
Barr Group connects attorneys with rigorously vetted expert witnesses across software, electronics, pharmaceuticals, medical devices, economic damages, and more — in the US and internationally.
Deep expertise across
every technical field
We started in software and electronics. Then attorneys in other fields started calling and we found that the same rigorous methodology translated.
Software & Electronics
Our founding strength. Source code review, firmware, embedded systems, hardware design, reverse engineering, and failure analysis.
Today we support cases across a broad range of technical and scientific disciplines, with hundreds of experts under contract and thousands more in our proprietary database.
Pharmaceuticals & Life Sciences
Hatch-Waxman ANDA disputes, biosimilar litigation, formulation chemistry, bioequivalence, and FDA regulatory.
Economic Damages
Lost profits, reasonable royalties, unjust enrichment, and damages modeling with experts who communicate complex financials clearly in court.
Medical Devices
Device design and defect cases, FDA regulatory matters, software-driven medical systems, and product liability support.
Materials & Engineering
Structural failures, materials science, manufacturing defects, and industrial accident cases across mechanical and civil engineering disciplines.
What we do
From initial consultation to courtroom testimony, we support every stage of your case.
Testifying Expert Witnesses
Trial and deposition testimony from experts with deep technical credentials and proven courtroom composure.
Consulting Expert Witnesses
Non-testifying technical support — strategic case guidance, document review, and expert prep without disclosure requirements.
Source Code Review & Analysis
Independent software audits by engineers who understand what they're reading — not just running tools, but interpreting findings for legal context.
Reverse Engineering & Forensic Analysis
Hardware and software investigation — disassembly, protocol analysis, and technical reconstruction to support IP and product liability cases.
Expert Reports & Declarations
Court-ready technical documentation — clear, defensible, and prepared with cross-examination in mind from the first draft.
Built from the inside out.
Barr Group started as one of the most respected embedded software and electronics engineering firms in the world. For over a decade we built real systems with software and hardware, doing the kind of deep technical work no other expert brokerage firm has experience with.
More and more attorneys were calling for help with patent cases, trade secret disputes, product liability. They weren't looking for a directory listing but wanted engineers who actually understood what they were looking at. And we did.
The methodology that
works in any field
We built one of the deepest expert networks in software and electronics. Then attorneys in pharma, medical devices, and other fields started calling. Turns out rigorous vetting and deep technical prep work everywhere.
Founded by Engineers,
Not Recruiters
We have the technical background to evaluate whether an expert truly understands the technology — not just their CV. Faster onboarding, sharper opinions, and experts who hold up under cross.
Conflict-Checked Against
177,000+ Cases
Before recommending anyone, we check testimony history, prior Daubert challenges, and opposing-party engagements across USDC, ITC, PTAB, and international proceedings. No surprises at deposition.
We Stay in the Middle
By Design
We manage the full expert relationship — scheduling, deliverables, billing, and any difficult conversations. One point of contact, one monthly invoice, no friction between you and your witness.
Trusted by attorneys
