Sonos Wins $32.5 Million Patent Infringement Victory Over Google (theverge.com) 23

Google has been ordered to pay Sonos $32.5 million after a jury verdict found that Google's smart speakers and media players infringed on one of Sonos' patents. The Verge reports: The legal battle started in 2020 when Sonos accused Google of copying its patented multiroom audio technology after the companies partnered in 2013. Sonos went on to win its case at the US International Trade Commission, resulting in a limited import ban on some of the Google devices in question. Google has also had to pull some features from its lineup of smart speakers and smart displays.

Last August, Google sued Sonos over allegations that the audio company infringed on Google's smart speakers and voice control technology. This most recent trial started earlier this month, with Google spokesperson Jose Castaneda telling Reuters at the time that the case pertains to "some very specific features that are not commonly used" and that Sonos "mischaracterized our partnership and technology." Neither Google nor Sonos immediately responded to The Verge's request for comment.

Sonos didn't come out of the case completely victorious, however, as the jury decided that Google's Home app didn't infringe on a separate patent filed by Sonos. The judge also told jurors to "disregard a $90 million damages estimate from a Sonos expert witness, saying he had decided that some of the evidence provided was inadmissible," Law360 reports.

    If I understand the patent correctly, it basically amounts to a patent on having preset configurations that set a bunch of remote speakers to particular volume level and take input from a particular source and route it to specific destinations.

    Unless I'm missing something, this patent consists of four significant parts expressed in various ways:

    • A protocol for controlling an audio source (without actually describing the protocol in enough detail to recreate it).
    • A routing mixer. We had stuff like that in the TV industry back in the analog TV days. Other than the touchscreen and the use of packets over Ethernet/Wi-Fi rather than analog signals, this isn't novel.
    • A protocol for synchronizing playback between two speakers (without actually describing the protocol in enough detail to recreate it).
    • The claim that these devices all talk to each other and tell each other when they are going to start doing specific things (which obviously would have to happen for any of the above to be possible, and again, presented without any actual information about how it works).

    They did all of the things that a normal audio amplifier or routing mixer has done for the last fifty years, but instead of wires, they presumably sent low-latency UDP traffic to an endpoint to make it start playing audio, and synchronized the bit clocks on various devices using some non-described network protocol so that they output the audio buffers synchronously.

    That said, that they left out all the details, like the low-latency UDP part, how the synchronization works, etc. so I'm literally guessing about the nature of the invention based on how I would implement it if I were asked to build what they are talking about. They don't explain how *anything* is done, as far as I can tell. There's nothing about how the synchronization works — only that it happens. There's just a bunch of meaningless gibberish about how one device tells another device that a secondary output device is now going to be synchronized to it, in various combinations, plus vague nonsense about possible scene configurations (e.g. an evening scene or whatever).

    This is a patent that is so completely information-free underneath the almost impenetrable legalese that at least at first glance, it appears to have no real value in terms of what patents are supposed to do, which is documenting how an invention works and contributing to the state of the art. But at first glance, I would say that they basically are just implementing Dolby Digital (1986) over a packet-switched network, and that the only thing potentially novel is their synchronization mechanism, which this patent doesn't even describe.

    I'm seriously struggling to understand how this patent withstood a challenge on its merits. The only reason this wasn't done in home speakers decades ago is because sending audio over Wi-Fi wasn't practical until recently, so having separate synchronized amplifiers in individual consumer-grade speakers over Wi-Fi wasn't really feasible. I'm firmly of the opinion that if the invention that your patent covers is a natural evolution of existing concepts, and if the only thing even slightly novel or non-obvious is the need to do it in the first place, your patent should not be awarded.

    What am I missing? Where's the actual meat of this patent, where they tell how they did this? What was so novel about this that is worth enough money to feed every homeless person in San Francisco for four months?

    Patents should really just not exist at this point. When they began allowing obfuscated crap like this, the whole benefit to society from patents evaporated. So why are we still awarding them?

      The claims are pretty hard to read for sure.

    • Probably because they did not demo any Yamaha AV system that has dozens of presets, and an auto-tune balance calibration microphone, let alone an impossible to understand remote control. So ok, its now via wireless, although Dolby had some IR systems also in play. A studio master mixer console also achieves the same outcome. Google should just open source a universal protocol per speaker (with lighting too), and cite the Yamaha protocol(s) as out of patent space. The downside to this is anyone can come alo

        Up to a point, yes, though you're usually limited to a mix bus and a couple of aux buses, so there are limits to what you can do. (With modern digital boards, this might not be the case anymore; I've never dealt with one.) But that's why I pointed out the example of video routing mixers, where we could arbitrarily patch inputs to outputs, have specific sets that overrode all or part of a configuration, etc.

        For example, you could have your default configuration, then have a configuration that switches one

        • Good point. I think Yamaha was limited to 8 speakers. The the judge when assessing damages should have wiped out those with less than 8 speakers. That would have really cut alleged damages.
    • The USPTO gets paid when you apply, again when you reapply, and again when the patent is granted. Then they get paid AGAIN when someone gets the information they need to challenge the patent, and AGAIN when they actually challenge the patent, and they get paid AGAIN if you successfully challenge the patent and file your own patent...

  • That patents need not be nonobvious, original, or particularly clever. All they need are trolls with wallets to pay lawyers behind them.

    You too can patent 7 + 4 and shakedown any company that uses math.

Real Programmers think better when playing Adventure or Rogue.
