Huawei's lawsuit targets T-Mobile for alleged unlicensed use of 4G patents

It isn’t enough for Huawei to challenge the biggest smartphone maker in the world — now the Chinese company is targeting one of the top four mobile carriers in the United States.

Huawei filed a patent dispute lawsuit against T-Mobile in the U.S. District Court in Eastern Texas on Tuesday because, the company says, the carrier is using Huawei’s 4G patented technology and isn’t agreeing to make a deal. The technology revolves around Huawei’s 4G Wireless Network Essential Patents, and the Chinese company says it is ready to offer a license with terms and conditions “that are fair, reasonable, and non-discriminatory,” or “FRAND.”

“Huawei brings this action because T-Mobile has refused Huawei’s FRAND offer, but continues to practice, use, or otherwise comply with 4G standards covered by Huawei’s 4G Wireless Network Essential Patents by operation of its cellular telecommunications network,” according to court documents.

Huawei says that the unlicensed use of its 4G patents also extends to MetroPCS, which T-Mobile owns. The dispute began on June 6, 2014, when Huawei allegedly reached out to T-Mobile about a licensing deal. Huawei wanted the carrier to sign a nondisclosure agreement during the process, but T-Mobile repeatedly refused. The Chinese company then filed patent-infringement actions in January of this year — and that’s when some talks began.

“On February 5, 2016, T-Mobile responded – for the first time – that it would be willing to enter into an appropriate nondisclosure agreement, and identified several terms that it wanted to include in the nondisclosure agreement,” according to Huawei’s suit. “T-Mobile also stated in that letter: ‘Rest assured that when and if Huawei deems it appropriate to make a FRAND offer, T-Mobile will give such an offer reasoned and full consideration.’”

But even after Huawei agreed to T-Mobile’s nondisclosure agreement demands, the carrier reportedly began to delay discussions about the licensing deal until it ultimately rejected it in May.

“Huawei owns numerous patents which are essential to the operation of LTE network services,” William Plummer, Huawei’s vice president of external affairs, tells Digital Trends. “We’re prepared to grant licenses to our essential patents on fair, reasonable, and non-discriminatory (FRAND) terms, to T-Mobile, and any other licensee. The purpose of the lawsuit is to resolve a dispute over the terms of such a license.”

This isn’t the first run-in between the two companies. T-Mobile sued Huawei in 2014 for allegedly stealing designs of a robot called Tappy — the robot simulates tapping on mobile phones, and was built to reduce the number or returns and unhappy T-Mobile customers. That case is still active, and a T-Mobile representative simply pointed to it when asked about Huawei’s new lawsuit filing. It goes on trial on Oct. 31.

Here’s another big reason why T-Mobile 5G dominates AT&T and Verizon

T-Mobile continues to command a massive lead in offering the best 5G experience among U.S. carriers. A few weeks ago, a report from Ookla revealed that T-Mobile is leaving its rivals in the dust; now Opensignal has confirmed that not only is the Un-carrier’s lead increasing in raw speeds, but it’s leading the way in taking 5G into the mainstream.

According to Opensignal’s latest 5G Experience Report, T-Mobile not only offers the fastest 5G experience in the U.S. by a sizeable margin but on average, customers on T-Mobile spend nearly 50% of their time on the carrier’s 5G network.

T-Mobile is leaving AT&T and Verizon in the 5G dust

Ookla has just published its latest market report revealing where U.S. mobile carriers and smartphone manufacturers stand in terms of providing the best 5G and 4G/LTE services.

Not surprisingly, T-Mobile remained in the top spot during the fourth quarter of 2022, eclipsing its rivals when it comes to median download speeds. What may be more surprising is that T-Mobile has increased its lead, clocking in at 151.37Mbps overall and 216.56Mbps for 5G, breaking the 200Mbps barrier for median 5G speeds across all bands for the first time.

It’s late 2022, and Verizon and AT&T still can’t beat T-Mobile’s 5G network

It’s been 10 months since Verizon and AT&T flipped the switch on their new C-band 5G spectrum, but it appears both carriers still have their work cut out for them if they want to catch up to T-Mobile.

Market analyses and independent tests have agreed for years that T-Mobile is the fastest and most reliable 5G carrier in the U.S. That’s not surprising as it had a massive advantage by holding licenses for the crucial midrange spectrum that provides the best balance between range and speed. While Verizon’s early high-frequency mmWave rollouts allowed it to boast raw speeds that were significantly faster, those were confined to about 1% of its subscriber base.
