First expert review confirming bilateral FRAND offer. First Brazilian-merits based PI over cellular SEPs.
Context:
- Last year, research and licensing firm InterDigital started cellular standard-essential patent (SEP) enforcement actions against China-based Transsion, the African market leader and a major player in other price-sensitive markets such as Latin America (October 31, 2025 ip fray article).
- Brazil has become one of the world’s most important SEP infringement jurisdictions.
What’s new: Today, InterDigital announced that it has won a Brazilian preliminary injunction (PI) over two 5G SEPs, as a result of which “Transsion is prevented from selling 5G-compliant devices in Brazil”. The Rio de Janeiro State Court granted the dual PI based on an expert report determining that both patents-in-suit are essential to the 5G standard and that InterDigital’s royalty demand is fair, reasonable, and non-discriminatory (FRAND).

InterDigital’s Chief Legal Officer, Josh Schmidt, said:
“As a foundational innovator in cellular wireless, our research provides the building blocks for today’s 5G networks and devices and enables newer players like Transsion to quickly scale its business and enter new markets.
“Transsion should pay fair value for technology that it uses every day and cannot be allowed to gain an unfair advantage over so many of its competitors who have paid for a license to our portfolio.”
