UK's Top Court Reopens a $32-Per-Car Patent Fee

Key takeaways

The UK Supreme Court's July 27 ruling in Tesla v InterDigital ([2026] UKSC 27) revived Tesla's challenge to Avanci's $32-per-vehicle 5G patent-pool licence, meaning any company that embeds standard-essential-patent connectivity can now ask an English court to test whether a pool's flat per-unit fee is actually fair rather than simply pay it.
The five-justice panel rejected InterDigital and Avanci's argument that Delaware's Court of Chancery was the proper forum, confirming England as a venue where implementers can force judicial scrutiny of global patent-pool rates tied to UK-registered patents.
The court's core legal principle - that joining a licensing pool does not release a patent owner from its own FRAND commitment - applies to the roughly 65 to 89 licensors inside Avanci's platform and to any comparable pool covering WiFi, 5G or future 6G technology, not just automotive SEPs.
The ruling does not set a new rate: the case now goes to trial to determine whether $32 per vehicle is actually FRAND, so companies with UK-patent SEP exposure should treat this as the start of a longer legal process, not a closed question.

What the Supreme Court Actually Decided on July 27

On July 27, 2026, a five-justice panel of the UK Supreme Court - Lord Sales, Lord Briggs, Lord Hamblen, Lord Burrows and Lord Kitchin - handed down judgment in Tesla, Inc and another v InterDigital Patent Holdings, Inc and others, cited as [2026] UKSC 27. The case had reached the country's highest court after Tesla lost at the High Court and then, by majority, at the Court of Appeal, where only Lord Justice Richard Arnold had sided with Tesla's position.

The Supreme Court reversed that majority. It held that Tesla has a real prospect of success in arguing that a fair, reasonable and non-discriminatory licensing obligation applies to a patent pool's own licence offer, not just to the individual patent owners inside it, and that English courts have jurisdiction to hear the claim. Tesla's case can now proceed to a full trial rather than being struck out.

The $32-a-Car Number Behind the Fight

The dispute centers on Avanci, a licensing platform that bundles standard-essential patents from dozens of owners - reported at somewhere between 65 and around 89 licensors, InterDigital among them - into a single 5G connected-car licence. Avanci's current published rate is $32 per vehicle for 5G, more than double the roughly $15 per vehicle it charged for 4G. Tesla wants to sell 5G-enabled vehicles in the UK and argues that rate was never negotiated with it, only presented as a fixed price to accept or refuse.

Roughly 7 percent of the patents inside the Avanci pool are UK-registered, which is what gave Tesla's lawyers, led by Ligia Osepciu of Monckton Chambers and instructed by Powell Gilbert, a foothold to bring the claim in England rather than accept Avanci's preferred venue. InterDigital and Avanci argued Delaware's Court of Chancery, not London, was the right forum; the Supreme Court disagreed.

Why This Reaches Every Connected Product, Not Just Cars

Most coverage of the ruling framed it as a Tesla story. The more durable part is the legal principle behind it: a patent owner's FRAND commitment to a standards body does not evaporate the moment it hands pricing over to a pool administrator. That holding is not written to apply only to cars or only to Avanci - it applies to any standard-essential-patent pool covering WiFi, 5G or the 6G technology now in early deployment, wherever the pool includes UK-registered patents and the implementer can find a jurisdictional gateway into English courts.

That is the part patent pool administrators will feel first. For a decade, pools like Avanci have operated on the practical assumption that a published flat per-unit rate is take-it-or-leave-it: negotiate individually with dozens of SEP owners, or accept the platform's number. This ruling tells every implementer - wearable makers, industrial sensor vendors, smart meter manufacturers, drone builders, anyone shipping a UK-patent-covered radio - that the platform's number is now something a court can be asked to test, not something they have to simply absorb into their bill of materials.

What Comes Next, and What Doesn't Change Yet

It is important to be precise about what the Supreme Court did not do. It did not rule that $32 per vehicle is unfair, and it did not set a new rate. The justices found only that Tesla has raised a serious issue that deserves a trial; the actual FRAND rate-setting exercise, weighing evidence from both sides on cost, comparable licences and pool economics, still has to happen. The number that comes out the other end could land at $32, above it, or below it.

For any business licensing cellular or WiFi connectivity into a new product line, the near-term change is not price - it is leverage and legal risk. English courts are now a confirmed venue for testing pool rates tied to UK patents, which should factor into how connectivity suppliers and component buyers negotiate pool licences and budget for potential litigation, even while the substantive rate question for Avanci's 5G tier remains open until trial.

Frequently asked questions

Did Tesla win the case outright?

No. The Supreme Court found Tesla has a real prospect of success and revived its claim for trial; it did not rule that the $32-per-vehicle rate is unfair, only that Tesla is entitled to have a UK court test that question.

Does this ruling set the actual FRAND royalty rate?

No. The Supreme Court's decision is about jurisdiction and the legal principle that FRAND obligations survive pool licensing; the rate-setting trial itself has not yet happened.

Does this only affect car makers?

No. The legal reasoning applies to any company implementing standard-essential patents licensed through a pool or platform administrator, covering products from wearables to industrial sensors wherever UK-registered patents and English jurisdiction gateways apply.

Can InterDigital and Avanci still appeal?

The Supreme Court is the UK's final court of appeal, so this jurisdictional ruling stands; InterDigital and Avanci's remaining options are to contest the substance of the FRAND rate at the trial the Supreme Court has now allowed to proceed.

The headline read as Tesla versus InterDigital. The precedent is Avanci's entire flat-fee patent-pool model versus every future implementer's right to ask an English court whether that fee is actually fair - a question pool administrators have spent a decade treating as already settled.
