A bit over a year ago, Qualcomm started the process of suing Apple at the US International Trade Commission (ITC) over alleged patent infringement. At the time, Apple was accused of violating six Qualcomm patents, ranging from power-saving technology to processor design. And while the case is far from over, according to Reuters the ITC has delivered its initial determination, finding that Apple has violated one of the six patents. Importantly, however, the ITC has also ruled that they will not be imposing an import ban, as Qualcomm originally requested.

All told, Apple stands accused of violating multiple Qualcomm patents due to a complex intermix regarding the use of Intel modems in their phones. Qualcomm’s case does not directly accuse the Intel modems of being infringing, but does claim that the resulting implementation in Apple’s phones violates those patents. Apple in turn pays royalties relating to these patents for phones using Qualcomm’s modems, but not on phones using the Intel modems.

This latest development comes as the ITC has slowly whittled the case down over the past year. While Qualcomm’s complaints originally involved six patents, earlier this year half of the patent claims were removed from the case, leaving just three patents.

The ITC, in turn, has ruled today as part of its initial determination that Apple has indeed violated a Qualcomm patent, albeit just one of those remaining patents – what Reuters calls “related to power management technology”. We’re waiting on the ITC to publish the formal decision in order to confirm which specific patent it was, as all three remaining patents are related to power efficiency.

Update: The US ITC has since published the Initial Determination. Apple has been found to infringe on claim 31 of the '490 patent. This claim covers "wherein the modem processor is further configured pull data from the application processor after transmission of the modem processor to application processor data and before the interconnectivity bus transitions from an active power state to a low power state."

(2014)
Direct scatter loading of executable software image from a primary processor to one or more secondary processor in a multi-processor system. In a multi-processor system, an executable software image including an image header and a segmented data image is scatter loaded from a first processor to a second processor. Enables “flashless boot” which allows your
smartphone to connect to the internet quickly
after being powered on, while extending battery
life and reducing memory size.
9,535,490
(2017)
Power saving techniques in computing devices. As the name implies. Enables the applications on your smartphone to
get their data to and from the internet quickly
and efficiently by acting as a smart “traffic cop”
between the apps processor and the modem.
9,608,675
(2013)
Power tracker for multiple transmit signals sent simultaneously. Techniques for generating a power tracking supply voltage for a circuit (e.g., a power amplifier). The circuit may process multiple transmit signals being sent simultaneously on multiple carriers at different frequencies. Enables a mobile device to send high-speed data
such as live video from your phone by combining
many lanes of traffic into a data super-highway
while prolonging battery life.

Notably however, this initial determination is not final, as it's part of the longer trial process for the ITC. The case will next go in front of the entire commission, who will be reviewing the findings. The commission, in turn, can either agree with the findings or send it back for further review, so the case is far from closed. However for the moment, having avoided an import ban, this is essentially a win for Apple, and both they and Qualcomm (and Intel) are treating it as such.

The initial determination in this case comes as Apple has begun phasing out Qualcomm modems entirely. The latest iPhone XS models are powered solely by the Intel modems, which for Qualcomm makes the issue all the more important as Apple will be importing an ever-larger number of potentially infringing phones.

Ultimately the current case will likely be resolved in 2019, assuming that there are no appeals. The ITC has set January 28th, 2019 as the target date to complete the investigation.

    If it were Huawei instead of Apple, we can bet there would have been an import ban. Reply

    Before people get too excited about this, I'd remind everyone that yesterday on Appeal the Moshovos patent claim against Apple by UWisc was rejected (and the associated $500 million fine dropped).

    That suit struck me at the time as ridiculous because UWisc is known to be extremely litigious about the patent, meaning that it would be crazy for Apple to simply violate the patent and take their chances; they knew how UWisc would react; meaning in turn that Apple presumably did something different (built a load-store aliasing predictor that operated differently from Moshovos), but UWisc couldn't believe anyone could do anything different...

    I mention all this because this is a common pattern I see in patents -- the inventor of the patent is so proud of what they did that they literally cannot imagine alternatives -- meaning that they then see everywhere around them people who "must" be infringing their patent because they "have to" be doing things they the inventor invented. My single brush with this side of patent law came in the late 90s, before the MPEG-LA patent bundling, when I was at Apple. One of the large MPEG companies wanted to sue us for one of the "essential" MPEG patents (or so they imagined) having to do with reordering MPEG frames. (Remember that MPEG orders frames in the bit stream differently from display order.) The discussion started with their lawyers presenting the issue, describing how their patent allowed for rearrangement to display order, and more or less saying "well you have to rearrange to display order, and that's the only way to do it, so I guess you're infringing".
    It took them a while for me to convince them that, no, the way they were doing it is the OBVIOUS way to do it, but is in fact rather crappy because it's fragile to bit-errors, and doesn't work well in the face of random access [let alone backward playback] so I did something very different.

    I fully expect at the end of the day this (and the larger drama of QC claiming "Apple deliberately stole our IP to give it to Intel") will play out in the same way --- a bunch of inventors certain their invention was so good everyone had to be using it will discover that, in fact, there are many ways of doing the same thing, some of them in fact a lot better.

    We always knew Apple was innocent; it's the courts that are biased against them. Reply

    "QC claiming "Apple deliberately store our IP to give it to Intel""

    If Apple actually stole the IP, while would they give it to Intel, Apple has technology to create the A12 and they surely could build an modem. If they actually stole the patent, they could skip Intel and make it them selves.

    It simple by looking at the patents - at least on the outside - they look to generic.

    This claim sounds like something on the kids at WCCFTech

    Umm, do you actually KNOW what I am talking about? Have you read the court documents?
    Here's the simple version:

    Maybe save the mocking until you know what you're talking about?

    I doubt it was Moshovos pushing the lawsuit, he was my professor and a pretty cool guy. He's not a patent troll suing ppl for using what's obvious.

    The Apple giving IP from QC to Intel is a very different can of worms and should be interesting.

    As if anybody in the U.S had the guts do anything that may hurt the cash cow that is Apple. They have sloshed around too much $$ around Washington to basically anything they like ! Reply
