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

Add as a preferred source on Google

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.

Oppo’s Bubble is the fun MagSafe accessory Apple still refuses to make
This tiny selfie screen is MagSafe accessory phones badly need
Oppo Bubble official images with the AMOLED display

Oppo has launched a new phone accessory in China called the Oppo Bubble, and it's surprisingly versatile. It functions like a selfie tool, while also being a tiny rear display, a playful phone add-on, and a fun accessory in general. All of this would have it dominate tech TikTok a few years ago.

Announced alongside the Reno 16 series, the Bubble is a compact magnetic circular display that attaches to the back of supported Oppo smartphones. The tiny gadget basically acts like a secondary screen that helps in taking better selfies, which is honestly handy. It is small, light, and customizable, while also upgrading your selfies or group photos thanks to the better rear cameras. You'd usually have to guess the framing with your rear cameras, but this just makes it work.

A developer built Quick Share from scratch for phones Google forgot, and it actually works
Bada gives the millions of Android devices locked out of Google's Quick Share a working file-sharing solution.
Electronics, Phone, Mobile Phone

Google's Quick Share is the kind of feature you don't think about until the day you need it and your phone simply doesn't have it. Huawei device owners live in that reality permanently, given that they don’t have access to Google Play services, and so does anyone running the Chinese regional build of Android. 

However, a developer with the handle Kyujin-cho just published an open-source Android app called Bada on GitHub that seems to solve exactly this problem. It does so by implementing Google's own Quick Share protocol from scratch, circumventing the lack of Google Play Services.
