The InterDigital TCL injunction, announced on 27 October 2026, bars TCL from implementing the High Efficiency Video Coding (HEVC) standard in devices it makes, imports or sells in Brazil. The order is preliminary and covers two patents that InterDigital says are essential to HEVC.
The ruling matters beyond one dispute. It shows that a Brazilian court has been willing to grant early, evidence-based relief on standard essential patents (SEPs), and that video codecs are now part of that picture.
What happened
According to InterDigital, the order came from the 3rd Business Court of the Judicial District of the Capital of Rio de Janeiro. The court relied on the findings of an expert it had appointed to examine the dispute.
InterDigital says the expert found that TCL infringes both patents, that the patents are essential to HEVC, and that InterDigital’s licence offers met its fair, reasonable and non-discriminatory (FRAND) obligations. InterDigital also said the court found TCL’s offers lower by “a different order of magnitude”.
HEVC, also known as H.265, is the compression standard behind much 4K television and streaming video. A television maker cannot easily remove a standard feature from a product line, which gives an order tied to the standard real commercial weight.
The dispute is not one-sided. The trade publication ip fray reported in February 2026 that InterDigital had filed actions against TCL in the Unified Patent Court (UPC), Germany, Brazil and India. On 4 August 2026, ip fray reported that TCL had responded with global HEVC rate-setting and antitrust suits in Shenzhen.
On that timeline, the Brazilian order arrived roughly 8 months after the filings. Because it is preliminary, it may still be challenged on appeal or replaced by a decision on the merits.
Not the first Brazilian win for InterDigital
The TCL order follows the same pattern as two earlier InterDigital cases in Rio de Janeiro.
On 11 September 2025, InterDigital announced a preliminary injunction against Disney from the 7th Corporate Court of Rio de Janeiro over two patents relating to AVC and HEVC video coding. A court-appointed expert again supported infringement. That case differed on one point: InterDigital said the expert found no reasonable and non-discriminatory (RAND) obligation arising from the encoder claims asserted.
On 1 April 2026, InterDigital announced a preliminary injunction against Transsion, also from a Rio de Janeiro business court. That order concerned two patents described as essential to 5G and prevented Transsion from selling 5G-compliant devices in Brazil. The court found InterDigital’s offer to be FRAND.
Taken together, the three cases show a repeatable process: an expert examination of infringement, essentiality and the licence offer, followed by a preliminary order. TCL extends that process from phones and streaming to consumer television hardware.
The wider picture in SEP enforcement
Europe offers a comparable route. On 22 November 2024, the UPC Mannheim Local Division gave its first FRAND decision in Panasonic v Oppo, granting an injunction covering 5 countries. It treated Oppo as an unwilling licensee and rejected its FRAND defence and counterclaim, while leaving the rate to the parties.
The English courts take a different line. On 28 February 2025, the Court of Appeal in Lenovo v Ericsson declared that a willing licensor would grant an interim licence while the English court set FRAND terms. The case arose against a background of foreign injunction proceedings, including in Brazil.
InterDigital’s own record shows how often injunctions now feature. In its third-quarter 2026 results of 29 October 2026, it reported revenue of USD 193.4 million, 17% above the same quarter of 2025. It said all 8 Disney patent cases decided so far had produced injunctions, including 2 new UPC orders. It separately reported a deal with an unnamed major personal computer maker, with final terms to be set by binding arbitration.
What it means for implementers in consumer electronics and streaming
Device makers and streaming services now face a realistic risk of preliminary orders in Brazil, a large consumer market, on video codec patents as well as cellular ones. Three practical points follow.
- Evidence on essentiality and infringement matters early. Brazilian courts have relied on expert examination, so detailed SEP claim charts mapping each claim to the standard text carry weight on both sides.
- Validity work can start before an assertion lands. A prior art search on the asserted family, including standards contributions and other non-patent literature, gives material for an appeal or a negotiation.
- Offer records count. Courts in Brazil and at the UPC have examined both sides’ offers in detail.

Synoptic IP’s view
Synoptic IP’s view is that Brazil has become an increasingly important venue for SEP enforcement, and that the TCL order shows video codecs now sit alongside 5G in that role. The reasons are in the record. InterDigital has won three preliminary orders in Rio de Janeiro within about 13 months, each resting on a court-appointed expert, and the UPC has shown a similar willingness to grant injunctions.
In Synoptic IP’s assessment, where relief can be obtained quickly now shapes FRAND negotiations as much as where rates are set. An implementer that plans only for rate-setting in one forum may find its exposure lies elsewhere.
The strongest counter-argument is that preliminary orders are provisional, and appeals may narrow or reverse them. The English approach to interim licences also gives implementers a route to keep products on sale while terms are set. Licensors argue that injunctions are needed to bring reluctant licensees to the table, while implementers argue that the threat pushes royalties above FRAND levels. Even so, the pattern in Brazil and at the UPC suggests quick injunctions are likely to remain a strong factor in negotiations.
