The following activities and email exchanges were compiled from the indictment signed on January 16th, 2019 (unsealed on January 28th). All bolded messages presented below are direct quotes from Huawei emails, as described in the indictment, while the supporting text has been compiled from the document's surrounding information.

What follows is a real-life, bumbling, corporate-tinged, international spy drama that played out over internal Huawei emails between 2012 and 2013, as related by US prosecutors:

Asked about licensing or purchasing Tappy, but TMO said no. They have no plans to sell the robot system to any phone manufacturer, including Huawei.

Per request for photos and technical specs of TMO robot (i.e. component serial numbers, hardware and software details) we were unable to gather relevant information. They say it is because of information security regulations. We were reminded that all Huawei employees signed non-disclosure agreements.

The main point is to figure out the Robot's specifications and functions. These are the benchmarks of products developed by ourselves.

T-Mobile is not willing to share the detail of robot tech/docs with Huawei or any manufacturers. They refused to provide us the details of robot hardware and software specifications.

This email is just a kindly reminder for the information we need to build our own robot system and kindly feedback the information we need in the attachment...

Huawei USA engineers have accessed the robot lab... They know how TMO robot work and system info. I asked them to write down the info in detail and then send to Huawei China.

I am sorry we can not get more information from TMO and we can't finish the whole PowerPoint as we talk about. And as you know, we can take some pictures of test procedure and setting. Hope it is useful to HQ R&D.

Pictures of Tappy robot and software interface attached.

We got not much information from TMO on these questions that you guys asked. Again, TMO won't want to share any more information about their robot system with us. However, we still try to find more information during our test in TMO robot lab. But it won't expect any time soon.

We are still working on the Robot system and we had some issues with the system at the moment. More information on Tappy is needed. Are software test strips optimized for each device? What is Tappy's touch speed? How is the rubbed tip installed? Is there air space in the rubber tip?

See attached photos of Tappy.

We need more technical information, specifically the response time accuracy of TMO's mechanical arm.

TMO will not give us this information.

Once again, we CAN'T ask TMO any questions about the robot. TMO is VERY angry the questions that we asked. Sorry we can't deliver any more information to you.

I think a Huawei China engineer should come to Seattle and observe Tappy directly. You will learn a lot in knowledge and experience.

From the results of the recent xDeviceRobot system verification, there is still a definite disparity with T-Mobile.

H.L., can you collect information about the TMO robot arm and tip? We need contact area, hardness and pressure.

Gathering info from TMO is risky. I recommend contacting the robot manufacturer instead. Going through TMO would only backfire, especially after signing a confidentiality agreement at the TMO laboratory, the relevance of this information to us is very sensitive.

We are still not on par with TMO robot. Please send more information about calibration standards, delay calculations and software.

First of all, I am glad that HQ R&D has been continuing to improve the Huawei robot system. Based on the test on TMO's phone we do see a big difference of test results between TMO robot and Huawei robot. I think we have a lot of work to improve our robot performance. The difference between two is not only the hardware but also (most importantly) the software. TMO has spend much more money on software than hardware.

Once again, we can't get any further information about TMO robot system from TMO. They have complained to us a lot about this because we asked them too many questions of the robot based on HQ's request. TMO said to me that if we ask them again such questions, they don't allow us to use their robot Lab. TMO has set up a security system by putting camera into the robot Lab. I think everyone knows what this means. We can't provide any further information to HQ because we can't get anything from TMO.

Once again, I suggested HQ to send an engineer to TMO for a hands-on experience by playing the robot system. I believe this would give HQ robot team a huge benefit in understanding TMO robot system from hardware and software, as well as operation.

Here's why TMO will not share info with us, as far as I can tell:

TMO is clear that those such as Huawei and Samsung are not only supplying TMO, but are also supplying their competitors such as Verizon, ATT, and other carriers.

If every Vendor is helped to establish TMO testing environment and standards, it would certainly also improve the product quality, etc. of each Vendor's competitors, which is equivalent to TMO doing a good deed for the industry. TMO took about four years of time and lots of resource optimization to develop the Robot system, and it contains TMO's intellectual property rights. TMO can provide a free testing environment for each Vendor, and it can ensure that this system only services TMO products. This only enhances the competitiveness of TMO.

Access to Tappy by our engineers on the ground is strictly controlled. They are limited to usage of TMO's robot, and everything else is categorically denied.

Due to answering headquarters' questions, our employees have had two complaints raised against them, and it was declared that if we inquired again, Huawei's credentials for using the TMO Robot Laboratory would end. I echo previous suggestions to send an engineer from headquarters to see Tappy in person.

>There are a number of goals for my trip to T-Mobile HQ, but mainly-







I expect to arrive in Washington on May 11.

A.X. has let me into the Tappy laboratory twice over the past few days. Both times we were discovered by a T-Mobile employee and I was asked to leave, since I wasn't allowed to be there. I observed the robot on both visits and took pictures on the second.

I went once more today to TMO's mechanical arm testing laboratory and gained an overall understanding of the test environment. I summarized it, please take a look in the attached document and pictures.

TMO has made it clear that I am not allowed to re-enter the robot laboratory. Going forward, A.X. will help you get a deeper understanding of the remaining information.

Due to recent and repeated violations of T-Mobile's on-site rules, Huawei USA's access to the Tappy laboratory has been revoked. All Huawei USA employees must return their badges to T-Mobile, with the exception of A.X., who will be the only Huawei USA employee with access to the testing facilities. This is only so Huawei can complete limited testing on in-progress projects.

The engineering team needs more details about the TMO robot:













We'll certainly help if we can; this period is very sensitive.

In regards to photos and videos, after TMO gives back our badges, I'll send it back home. No need for home to keep reminding me.

The xDeviceRobot team needs specs on the arm. Specifically, the diameter of the end tip of the conductor stick.

A.X. was able to remove the robot arm from the laboratory without being detected and I took exact measurements. However, TMO quickly discovered the arm was missing and A.X. was forced to return the part the following day. A.X. told them it was taken by mistake. Our access to the lab has been completely revoked and Huawei USA employees are no longer allowed inside the facility unsupervised.

I've attached detailed measurements of the arm. See pictures for details.

Can you measure the conductor stick with a caliper device?

F.W. has already sent the pictures home.

The criminal charges lodged against Huawei in the T-Mobile case are just part of the Chinese company's concerns at the moment. This week, the US filed 23 total charges against Huawei related to trade-secret and sanctions violations.

The 13 sanctions charges stem from the company's dealings with Iran. Huawei CFO Meng Wanzhou is accused of committing fraud to bypass Iran sanctions and bring US-made technology into the country. She was arrested in Canada last month at the request of US authorities. Though she's currently out on bail, she faces extradition to the US.

Regarding the T-Mobile situation, Huawei says the case has already been settled. And it has been, in civil court -- after hearing the story in 2017, a Seattle jury forced Huawei to pay T-Mobile $4.8 million in damages. However, that was all over breach of contract, not trade-secret violations. The jury said Huawei hadn't maliciously or willfully misappropriated the data it stole from T-Mobile, and no money was awarded for the trade-secret claim.

A Huawei representative sent the following statement to Engadget this week:
