Standard-Essential Patent & FRAND Expert Witnesses
Standard-essential patent (SEP) and FRAND disputes are among the highest-value technology litigation heard anywhere, and among the most technically demanding. They turn on whether a patent is genuinely essential to a standard, whether a product infringes, whether the patent is valid, and what a fair, reasonable and non-discriminatory licence should cost. EVO fields expert witnesses who work at exactly that intersection of wireless engineering, standards and patent law.
Our deepest bench
Telecommunications, semiconductor and electronics is EVO's single deepest specialism. Our bench includes experts who have prepared expert reports and given live evidence in telecoms patent disputes, and who understand both the engineering and the standards process that these cases depend on. Where a matter turns on the standard and the silicon that implements it, we can field the expertise to address both.
What our experts analyse
- Essentiality: mapping asserted claims to the relevant 3GPP specifications to assess whether a patent is genuinely essential to the standard
- Infringement: comparing accused products and their implementation of the standard against the asserted claims
- Validity and prior art: novelty and obviousness against the state of the art, including earlier contributions to the standard
- Claim charts and claim-construction support: detailed technical charts and the engineering basis counsel needs
Standards and technologies we cover
- Mobile communications from 2G and 3G through 4G and 5G, with emerging 6G
- The 3GPP standards process and the specifications that define these networks
- RF architecture and engineering, semiconductor and RFIC design, software-defined radio
- Network performance, interference and behaviour, and automotive radar systems
Where SEP and FRAND disputes are decided
These disputes are frequently heard in the Patents Court in London, a global forum of choice for FRAND rate-setting, and increasingly before the Unified Patent Court, alongside European Patent Office opposition proceedings and international arbitration. Our experts support proceedings across these forums, translating dense technical and standards material into evidence a court can rely on.
How we work
Every engagement is built to the standard the court expects under CPR Part 35. We produce clear, defensible expert reports, take part in joint expert meetings and joint statements, and give oral evidence under cross-examination, including concurrent evidence where the court directs it. An expert's overriding duty is to the court, and the evidence is built to survive scrutiny rather than to please the party instructing it.
