The Landmark Ruling: Samsung to Pay ZTE $392 Million

In a significant development for the global telecommunications industry, London's High Court has ordered Samsung Electronics to pay Chinese telecom giant ZTE a lump sum of $392 million for licensing its standard-essential patents (SEPs) related to mobile phone technology. The judgment, delivered by Mr Justice Richard Meade on May 1, 2026, in the case Samsung Electronics Co Ltd v ZTE Corporation [2026] EWHC 999 (Pat), marks a key moment in the ongoing patent dispute between the two tech powerhouses. This ruling determines the fair, reasonable, and non-discriminatory (FRAND) terms for a worldwide cross-license, covering ZTE's cellular SEPs for 3G, 4G, and 5G technologies.

The decision comes after Samsung sued ZTE in December 2024, seeking court-determined FRAND terms following the expiration of their previous cross-license agreement at the end of 2023. ZTE had demanded $731 million, while Samsung argued for no more than $200 million. The court's figure splits the difference but leans toward Samsung, reflecting a careful assessment of comparable licenses and portfolio strengths.

Background of the Samsung-ZTE Patent Saga

The rivalry between Samsung and ZTE over patent licensing has roots in their competition in the smartphone and network equipment markets. Both companies are major contributors to cellular standards through the European Telecommunications Standards Institute (ETSI), with ZTE declaring thousands of SEP families essential to 3G, 4G, and especially 5G technologies. Their initial cross-license was signed around 2016 and renewed in 2021, but negotiations for extension stalled, leading to multi-jurisdictional litigation.

ZTE, as the net licensor (its portfolio value exceeding Samsung's for cellular SEPs in the court's view), initiated infringement suits in China, Germany, Brazil, and the Unified Patent Court (UPC). Samsung countered in the UK, leveraging England's reputation for setting global FRAND rates, as affirmed by the UK Supreme Court in 2020.

Details of the UK High Court Trial

The trial focused on determining FRAND terms for a global license, primarily a lump sum payment from Samsung to ZTE. Samsung, the implementer, sought protection against injunctions while using ZTE's patents for network access in smartphones. The court examined expert evidence on portfolio comparability, using prior ZTE licenses with Apple and past Samsung deals as benchmarks, adjusted for factors like U.S. sanctions impacting ZTE's bargaining power historically.

Justice Meade rejected ZTE's top-down approach, favoring comparables, and noted ZTE's aggressive multi-forum strategy but did not deem it bad faith overall. The license covers ZTE's declared cellular SEPs, estimated at thousands of families, against Samsung's larger overall portfolio but weaker in key cellular areas.

ZTE's Robust Patent Portfolio

ZTE's strength lies in its SEP declarations to ETSI, with over 2,500 5G SEP families placing it in the global top 3, behind Huawei and Samsung. This portfolio is critical for 5G features like MIMO, LDPC coding, and network architecture. The UK court recognized ZTE's quality, but adjusted rates downward due to past low-ball licenses influenced by external factors like U.S. bans on ZTE sales.

For Chinese firms, this validates years of R&D investment, positioning ZTE as a 5G leader extracting value from global implementers.

How the Court Calculated the $392 Million Rate

The judgment used the comparable license method, starting from ZTE's prior deals (e.g., with Apple at low rates due to ZTE's limited U.S. presence) and Samsung's licenses with Ericsson/Nokia/InterDigital (ENI), discounted for ZTE's perceived weaker portfolio. Adjustments included 5G coverage (court assumed partial in old deal), covenant not to sue periods, and netting cross-license value. Samsung's revenue base for handsets was key, with rates around 0.1-0.2% typical for SEPs. The final lump sum reflects a 5-year term forward, deemed FRAND despite ZTE's higher ask.

Global Litigation Landscape

Parallel cases highlight forum-shopping: In Chongqing, China, courts favored ZTE with higher rates (up to $731M cited in UK). Germany (Munich/Frankfurt) granted ZTE injunctions after FRAND hearings; UPC dismissed Samsung's counterclaim as duplicative; Brazil reinstated ZTE's 5G injunction. This UK outlier ($392M) may face appeal, underscoring jurisdictional divergences.IP Fray analysis

Impact on ZTE: A Win for Chinese Innovation

For ZTE, the payment validates its IP strategy, providing funds for R&D amid U.S. restrictions. As a top 5G patent holder, it bolsters China's position in global standards, following Huawei's licensing successes. Revenue from SEPs supports expansion in base stations and handsets, enhancing competitiveness against Samsung.

In China, this is celebrated as proof of homegrown tech prowess, potentially inspiring more SEP assertions.

Samsung's Perspective and Costs

Samsung views the ruling as capping liability below ZTE's demand, protecting its massive smartphone sales (over 200M units/year). However, the $392M hit adds to legal expenses across fronts. Samsung leads overall SEPs but pays net here due to ZTE's cellular edge.

Broader Implications for FRAND and 5G Licensing

The judgment reinforces UK's role in global FRAND but highlights inconsistencies with China/Germany, risking more litigation. It adjusts for sanctions (non-FRAND factor), influencing future cross-border deals. For 5G rollout, stable licensing is crucial; this may pressure negotiations elsewhere.IAM Media coverage

Expert Opinions and Precedent

Experts note the subjective comparables approach vs. Germany's objective standards, predicting appeals. For China, it signals Western courts valuing Chinese SEPs, though at discounts. IP Fray calls it an outlier inviting forum-shopping.

Future Outlook: Appeals and Resolution

Both parties can appeal; ZTE may push for higher in China. Resolution could come via settlement, given business interdependence. For China, strengthens ZTE/Huawei in 5G ecosystem.

Conclusion: Milestone for Global Tech IP

This ruling underscores the maturing global SEP landscape, with Chinese firms asserting value. ZTE's victory highlights innovation payoff, while Samsung navigates costs. Watch for appeals shaping FRAND future.
