Satellite Expert Witness Services

Satellite Expert Witness Services

DVI Communications provides technical expert witness services in litigation involving satellite communications systems, including LEO, MEO, and GEO constellations, ground segment architecture, and satellite-terrestrial network integration. Our experts bring direct engineering experience with satellite and non-terrestrial network (NTN) technologies to patent, trade secret, and product disputes.

Why Satellite Litigation Requires Specialized Technical Expertise

Satellite disputes involve technical questions that general wireless knowledge does not answer: how constellation design (LEO versus MEO versus GEO) affects latency and coverage, how satellite-terrestrial handover and 3GPP non-terrestrial network (NTN) integration actually function, how spectrum coordination and beamforming are implemented, and how ground station and gateway architecture map to claimed system features. These systems increasingly intersect with terrestrial cellular standards, adding another layer of technical complexity.

Case Types We Support

Patent Infringement & Essentiality

Technical analysis of whether accused satellite systems, terminals, or ground infrastructure implement claimed features, and whether asserted patents are essential to satellite communication or NTN standards.

SEP / FRAND Disputes Involving Satellite-Terrestrial Integration

Support for disputes involving standard-essential patents tied to satellite integration with terrestrial cellular standards, where essentiality analysis depends on both satellite and cellular specifications.

Product Malfunction & Performance Disputes

Technical analysis of satellite equipment or service performance issues, distinguishing genuine defects from orbital, spectrum, or ground-segment factors.

Technical Specialties

Our experts’ backgrounds span LEO/MEO/GEO constellation design, satellite-terrestrial network integration and 3GPP NTN architecture, spectrum coordination, and ground segment and gateway systems — documented through decades of industry practice and prior expert testimony.

Frequently Asked Questions

How is a satellite expert witness different from a general wireless expert?

Satellite systems introduce orbital mechanics, propagation delay, and ground-segment considerations that require specific familiarity with satellite communications architecture, not just terrestrial cellular or WiFi experience.

What case types commonly involve satellite technical disputes?

Patent infringement and essentiality disputes tied to satellite or NTN standards, SEP/FRAND disputes involving satellite-terrestrial integration, and product performance cases involving satellite equipment or services.

How Engagement Typically Works

Because satellite-terrestrial integration is an actively evolving area, an early step is confirming which constellation type, standard, and integration layer govern the dispute. From there, the process follows the same structure as other technical patent and product litigation: detailed technical analysis, a written expert report, and testimony prepared to withstand challenges to both the technical conclusions and the standard or system at issue.

What Makes a Satellite Technical Analysis Credible

Satellite architecture spans space segment, ground segment, and increasingly terrestrial cellular integration, and a credible analysis has to be specific about which segment and which standard actually governs the claimed functionality.

When to Engage

Given how quickly satellite-terrestrial integration standards continue to evolve, engaging a technical expert early allows the analysis to account for the specific constellation, standard, and deployment context at issue from the outset.
