5G Expert Witness Services

5G Expert Witness Services

DVI Communications provides technical expert witness services in litigation involving 5G network standards, architecture, and implementation. Our experts bring direct engineering experience with cellular standards evolution — from earlier generations through 5G NR — to patent, trade secret, and product disputes involving next-generation wireless technology.

Why 5G Litigation Requires Standards-Specific Expertise

5G disputes turn on specific technical questions that general wireless knowledge doesn’t answer: how 5G NR’s architecture (network slicing, massive MIMO, beamforming, millimeter-wave spectrum) differs functionally from 4G/LTE predecessors, whether an accused implementation actually practices a claimed 5G standard feature, and how essentiality claims map to the underlying 3GPP specifications. This is a fast-evolving standard, and credible testimony requires an expert who has tracked its technical evolution directly, not one relying on secondary summaries.

Case Types We Support

Patent Infringement & Essentiality

Technical analysis of whether accused devices, base stations, or network equipment implement claimed 5G standard features, and whether asserted patents are genuinely essential to 3GPP 5G specifications.

Standard-Essential Patent (SEP) Disputes

Support for 5G-specific SEP and FRAND licensing disputes, where essentiality and technical implementation questions are especially dense given the complexity of 5G’s layered architecture.

Product Malfunction & Performance Disputes

Technical analysis of 5G equipment or device performance issues, distinguishing genuine defects from spectrum, deployment, or interoperability factors.

Technical Specialties

Our experts’ backgrounds span cellular standards evolution from earlier generations through 5G NR, wireless network architecture, and the deployment realities of 5G infrastructure — documented through decades of industry practice and prior expert testimony.

Frequently Asked Questions

How is a 5G expert witness different from a general wireless expert?

5G’s standard introduces architectural changes — network slicing, massive MIMO, new spectrum bands — that require specific familiarity with the current 3GPP 5G NR specifications, not just general cellular knowledge from earlier generations.

What case types commonly involve 5G technical disputes?

Patent infringement and essentiality disputes tied to 5G standards, SEP/FRAND licensing disputes, and product performance or malfunction cases involving 5G equipment or devices.

How Engagement Typically Works

Because 5G is still actively evolving, an early step in most engagements is confirming exactly which 3GPP release and feature set governs the dispute — a patent or product claim tied to an early 5G NR release may not map cleanly onto later standard revisions. This matters especially in essentiality disputes, where the technical analysis has to track the specific standard language in effect at the relevant time.

From there, the process follows the same structure as other technical patent and product litigation: detailed technical analysis, a written expert report addressing infringement, essentiality, or product performance questions, and testimony prepared to withstand challenges to both the technical conclusions and their application to the standard itself.

What Makes a 5G Technical Analysis Credible

5G’s layered architecture — spanning radio access, core network, and network slicing — means that a credible technical analysis has to be specific about which layer and which release of the standard actually governs the dispute. Overly broad claims about ‘5G technology’ without pinning down the specific technical mechanism at issue tend to collapse under cross-examination.

Because 5G deployments vary meaningfully between carriers, equipment vendors, and device manufacturers, technical analysis also has to account for real-world deployment variation rather than assuming a single reference implementation. This is where direct engineering experience with cellular standards evolution matters: understanding not just what the specification says, but how it is actually implemented and deployed in practice.

When to Engage

Given how quickly 5G standards and implementations continue to evolve, engaging a technical expert early — before infringement contentions or expert reports are due — allows the analysis to account for the specific 3GPP release and deployment context at issue from the outset, rather than retrofitting a theory to evidence gathered without that framework in mind.
