Have you had a closer look at that synchronize state stuff? I can't see much in the article.
> devices synchronize state using a LAN
If that has anything to do with music latency, then it's not "nothing substantial". It's their core business and their flagship feature. What they do well, that others could not, is playing multiple speakers perfectly in sync. Either stereo, or multiple rooms, almost as many speakers as you want, connected via wired network, or wireless, or by their on mesh system. And each speaker is basically a separate computer. It's not connected by analogue cable.
Anyone who were looking for Sonos alternatives with that functionality knows it's very hard to find and suddenly their prices become somewhat justified.

I admit I only briefly looked at each patent but even looking a second time, I can not find anything more specific basically the devices share clock information and calculate the difference between their clocks.
How is this different than syncronizing transactions between database servers or how GPS works?
I found a GPL license multi-room/device audio player that discussed this very lawsuit last year [1]. The developer raises the same point than anything like this will involve something resembling clock syncronization.
Looking through the lawsuit itself, about 90% of it is just comparing the end result of Sonos' & Google's products in that both let you add/group speakers, adjust volume and playback of the group, etc. I cannot find any claim that Google's implementation is a copy of Sonos'. It seems to try to sugest that is the case by bringing up that prior to Google's devices, Google had worked with Sonos and had access to details of their implementation.

Slim Devices' squeezebox had this feature before Sonos. I implemented it in high school using visual basic. The most non-trivial part is that if you try to synchronize an MP3 or other encoded stream instead of the decoded PCM stream, you end up seeking to mid-frame points which causes invisible adjustments to the seek point.
In the end, it's as simple as 'seek to this point' and then check if the point is off by less than some threshold, don't do anything. I did a few other fancy things like not seeking until the 'heart beat' lined up a few times in a row (duration in heartbeat was same as difference in time since last heartbeat).

Especially if we consider over 50 000 patents Google holds. They even tried to patent ANS compression that was made free for everyone by Jarosław Duda.
Well, the problem is, like with proof in math, afterwards it is always obvious, if not inevitable.
If parent post is correct, though, the "innovation" being protected is basically "we used to send signal over wire. Now that both endpoints have LAN, I'll send that signal over the LAN".
That, like many other software patents, is not "obvious is retrospect". It's not even "obvious idea at the time", it's less than that. It's just inertia. It's a decisionless decision.
It's patenting "not stepping in a puddle".

It's patenting "not stepping in a puddle".
But aren't patents supposed to protect implementations of ideas, not the ideas themselves? So then "keeping state between autonomous devices connected via LAN" seems like a worthwhile implementation, regardless of whether all the individual components were already existing in other technology domains.
Besides, I don't think that consensus-based asynchronous state protocols like Paxos were widely available in 2003 (and even so, implementing Paxos on a resource-constrained device like e.g. an Arduino might still qualify for a patent in 2021).

This is the problem with software patents. The border between ideas and implementation is not as clear.
Strictly the answer to your question is no. Copyright protects the implementation, and patents protect the ideas. But where's the difference between an idea, and a design?
For software, what's the difference between a design and the implementation? Sure, you may actually have a separate design (and not "the implementation is the design"), but in software the step from "design" to "implementation" isn't "manufacturing".
Sure, even for physical goods, and their patents, the patent is often not sufficient to create a working system.
For those holding software patents, they have to also list all ideas they have around that. Because there are patent trolls who check for new patents, and then file patents around that, creating a mine field so tight that you cannot even use your own invention.
Analogy: you patent a laser pointer, and immediately someone patents all possible use cases for a laser pointer they can think of (point at things during presentation, aim weapons, exercise cats[1], project things onto a wall, stick the laser pointer in a handheld device, have a button on the laser pointer, non-chargable batteries in the laser pointer, chargable batteries, mains powered, capacitor powered, etc… etc…
Anyway, a comment field is not sufficient to explore just why software don't fit well under the model of patents.
[1] this is a real patent, by the way.

This is something I never understood. When someone submits those type of patents, the patent officer most certainly knows the 'prior art' original patent exists. So why is this not patent 'obviousness'?

Aside from how the patent office no longer checks for prior art, but lets court fight it out, there's also the fact that technically these are not duplicates of prior art.
Technically using a laser pointer to exercise a cat is a new invention. Technically after that exercising a dog is another invention.
But even when not as obvious as that, imagine that you file a patent for the phone, and immediately someone patents every "step two", like the phone exchange, the ring, etc, to the point where you can't actually use your invention without licensing the next step.
That's one reason patent applications can be vague. It's not that they are not going to do the next step, is that they are patenting step 1 now, and are "inventing" step two right after.

Because the patent office now pretty much just checks if something is the same as prior art and let's the issue of obviousness or usefulness be settled in litigation.
One patent is just on how to set up a playback device by connecting to it directly and sending wifi details.
It's lucky they wrote "playback device" and not "device" otherwise the entire IoT industry would be violating it.

From another article[1] about this lawsuit, the Sonos side comments:
> "We believe that most people involved in wireless home audio today infringe on our patents in one way or the other."
So, either:
- most people are stealing their technology, or
- most people have come up with the same solution independently.
For some reason the second case seems more likely to me. Unfortunately for the patent law it doesn't matter if you invent something independently - you're still infringing.[2]

Society would be better off if patents were abolished.
Can you provide justification? In my view, they work when they promote competition and adequately compensate innovation. I know these are broad requirements, but I think that they're better than abolishing patents altogether.
This whole "competition" idea turns into the exact opposite when giant corporations buy others and gain all their patents. Motorola was bought because it came with over 10k patents, that is guaranteed to hurt competition.
I think patents make sense to some degree, but they should expire much quicker and should not be transferrable.
I think patents make sense to some degree, but they should expire much quicker and should not be transferrable.
Can you demonstrate that it actually works that way?
Patents are a pertect example of something that did make sense back when they were made. It was a trade off for having people share new knowledge which would benefit society as a whole. But as a price they got "monopoly" on using it for a while after sharing the patent.
But like many other things, it has been exploited, especially by big corporations. And the patents no longer work as intended. And the big problem is that theres so much money on the line that is it not easy to change. I would assume large corporations already spend absurd amounts of money on lobbying for the patent-rules to work in their favor.
Patents as a concept I am all for. It is a good way to make sure that new entrepreneurs can make it to market before "big-corp" steals their idea and just push them out. But they would have to change how they work to stop patent-sharks and the big exploitations by said big-corp.

Someone should organize a day of (inter)national strike against patents.

You say that patents no longer make sense, that they don't work, that they are exploited by "big corporations", but you don't really make an argument as to why you feel that way
The main problem with patents today is that the patent offices validate too many patent applications that do not contain anything new or non-obvious for any professional in their field.
Moreover, there are also many patent claims that are accepted and that refer to things that are either impossible or non-economical at the time when the patent is issued, but they are put in the patent to cover future devices that someone will be able to make after the current technological problems are solved.
In the distant past, most patent offices required a demonstration with a working device in which all the patent claims were embodied, so such bogus patent claims against future competitors could not be accepted.
Now, every year more patents are issued than anytime in the past, but most of them are just garbage that was not patented before just because everyone else would have been ashamed to attempt to file such patent applications.
The number of truly valid patents issued per year now is actually less than in the 19th century or at the beginning of the 20th century.
The same as for new movie scripts, it becomes more and more difficult to find something really original to which nobody thought before.

This reads an awful lot like the no true Scottsman fallacy. Care to elaborate?

It is impossible to find anywhere some statistics that will demonstrate either this opinion or its contrary beyond any reasonable doubt.
Therefore I base my opinion only on anecdotal evidence.
I have read carefully a lot of patents. I have read completely a few hundreds and I have browsed through the pages of a few thousands. I believe that few people happen to read so many patents, unless their job requires precisely this.
The number of the patents that I have read has been distributed rather uniformly over the years since the start of the USPTO archive until today. Because the number of patents issued per year has increased steadily, that means that I have read a larger part of the early patents than of the most recent patents, which are probably too many for anyone to read, unless they choose a very narrow area of applicability.
Besides a lot of junk patents, I have also read a lot of very valuable patents, which marked important points in the history of technology.
However, all the really valuable patents that I have seen have been issued before 1980. I have read a few patents from the eighties that were somewhat interesting improvements of prior techniques, but I have never seen any really innovative patent issued after 1990.
The patents that I have read were not chosen randomly, but they were found either by searching for the history of various important technologies or by following the references to other patents from the patents themselves.
I believe that the patents that I have read are more likely to belong to the better patents, not to the worse. Therefore I think that the failure to find recent innovative patents in my sample is likely to be consistent with the low proportion of such patents in the entire set of recent patents.
Not all patents are junk, many present competent solutions to various technical problems, but nevertheless they do not contain anything really new, they are just new combinations of already known techniques, that could be found after some work by any competent team that would be hired to solve that problem. Such patents fail the criterion for patentability of being "non-obvious for someone skilled in the art".
There are also patents that do not cover actual inventions but discoveries of various useful things, e.g. some new alloy that was not predicted by some theory, but it was just found in a series of empirical experiments, or some bacteria that were isolated from some environment and that happen to contain a useful enzyme.
Such discoveries are very valuable, but they do not have the novelty that they had much earlier when nobody had yet clear ideas about how to search for new materials or microorganisms.
Now such searches are well understood and it is mostly a matter of having enough time and money to enable such a discovery.

Their function was always to create more property to capitalize. I'm not sure you could argue that this wasnt the intended effect. The idea that they ever spurred innovation was the "big lie".
There have been historical periods of explosive innovation that coincided with lax or no enforcement of intellectual property rules but never, as far as im aware, the reverse.

The same thing could be said for software licensing, couldn’t it?
No GPL without software licensing. And no Linux without GPL.
By requiring the source to be available with the software, licenses drove the free software movement.

GPL also wouldnt be needed without software licensing.

Free but not open source.
GPL is here to make sure the source code doesn't stay secret, and it is an essential part of the Linux development process, the driver model in particular. In fact, I don't see how a community driven, widely supported, monolithic kernel could be made without a copyleft license.
Linux without GPL wouldn't be Linux, and out of the free OSes (BSD, GNU/HURD, Haiku, Minix, ...), Linux is the most successful.

If every employee of your company were able to take and release your source code anyway the GPL couldnt really make things more open.
No patents for trolls and giants.
Startups and labs should be able to patent so that they have a chance to make it in the market.

Any law operating at the company level will just be gamed with large amounts of shell companies. You just need to take a look at some of the more common tax evasion schemes to see how well that turns out.
A simplistic view that deserves an equally simplistic dismissal.
Patents as a whole? No.
Software/algorithm patents? Yes.
Software/algorithm patents? Yes.
Why only software patterns?
Hardware patents are by nature more narrow because they have to describe specific solutions to a problem. Software patents are often written as the idea of solving a specific problem using software, completely omitting the how. This makes them overly broad.
At least one of the Sonos patents in question is of that nature: it merely describes a system of distributed loudspeakers where one loudspeaker can set the volume of other speakers in the group remotely. The claims completely omit any actual solution that accomplishes that.

A patent is required to explain the invention to a level of detail such that those aware of the prior art can implement the same. So the _how_ portion can only be skipped if prior art already describes that.
So while there may be a difference on software and hardware patents in practice, this is not a valid difference in terms of what the legal provisions are.
So while there may be a difference on software and hardware patents in practice, this is not a valid difference in terms of what the legal provisions are.
This may technically be true, but especially the patents that get exploited by trolls are usually very vague. And the system gives too much incentive to write patents as broadly as possible.
To be fair, some of the patents that listed in another comment here as part of the lawsuit are quite precise in their claims. Their claims cover the actual algorithms for integrating another loudspeaker into a secure WLAN and for ensuring exact playback. That's the kind of detail level that I would expect from a patent. As a result, if you solve the same problem using a sufficiently different set of steps, you're fine.
There's a difference between the spirit in which a law or regulation is written and how it is applied in practice over time. In case of patents, this gap has become quite large. I think that this is why so many here want see changes.

This strikes me as an excellent point, how software patents tend to lack any actual solution, unlike traditional patents - I hadn't considered that before.
I think the process of accepting patents is broken, at least with software. If a reasonable practitioner could read some head-line and come up with a few solutions, there is not anything worth protecting. Ideas themselves should not be patentable in software.
On other hand I do think there is still need to protect innovation in more physical things. Like new manufacturing processes or material innovations like using novel chemistry.

I don't really see any fundamental difference between implementing your idea with big pieces of iron and implementing your idea with small pulses of electricity. If either is patentable, both should be.
Question is what sort of ideas deserve patent? Does one-click checkout deserve one? Or system to sell modifications of look of user interface delivered over radio?
I think there should be some line, probably non-obvious implementation.

I strongly disagree. Without patents, something like the Subminimal Foamer kickstarter would have been impossible. That was one guy inventing a new way to make milk foam and then commercializing it. Without patents, Amazon.com would probably have been flooded with fakes before he finished raising money for the first prototype.
Great. Apple patented a rectangle (https://www.theverge.com/2012/11/7/3614506/apple-patents-rec...), some dude patented a way to update a sports game (https://www.eff.org/deeplinks/2015/01/january-stupid-patent-...). I am not even getting into the whole patent trolling and companies suing each other because they are infringing upon each other's patents and then settling.
But no, for all the evil patents are we must have them, because some guy found a new way to make milk foam. Jesus ducking christ hacker news, this is almost as funny as Paul Graham writing an essay about why VC is great.

First off, I just really like milk foam with my coffee.
But mainly, my intent was to point out that patents might be a necessary evil to fight off copycats. Without that protection, I cannot imagine how any hardware startup could be successful, because the established players will always have the factories, tools, and experience so that they can scale up faster as soon as a new desired product is found.

I have a pile of Logitech Squeezeboxes running multiroom audio here, and it does all this sync stuff too, with much of that tech originating from 2001-2004.
Things were tight between them and Sonos until a Logitech pulled a Logitech and crippled the hardware lineup before killing the brand.
I now wonder if these patents had something to do with it.

They aren’t “guilty”. This is civil law, not criminal.
So Sonos is joining Google?
This article doesn't even say what the patents are. Useless.

(Edit: Formatting)
Thanks, here's my summary of claim 1 for each (that's the main bit that matters):
- https://patents.google.com/patent/US8588949B2
The ability to add separate speakers to groups, and control their volume via a single master volume control.
- https://patents.google.com/patent/US9195258B2
Covers two speakers synchronising playback by exchanging timing information between themselves. This one is not very clearly written.
- https://patents.google.com/patent/US9219959B2
A playback device that receives audio from the network and then equalises and plays it back, with two different equalisation settings. (This is for stereo output with two smart speakers.)
- https://patents.google.com/patent/US10209953B2
This is just a better worded and more specific version of the second patent. It describes how you would use timing information to synchronise playback. It's nothing clever - just the very obvious solution of using pings to measure the clock differences between the devices and then delaying the audio appropriately.
- https://patents.google.com/patent/US10439896B2
This is a description of the standard way of setting up smart devices - they announce their presence, you connect to them directly, send the wifi details, and then they indicate they have connected. I bet they wish they had just written "device" instead of "playback device" in this patent because then literally every smart device in the world would be violating it!
I was at least expecting some sophisticated synchronisation or room measurement stuff. But no, just 5 obvious patents that should never have been granted.

”a smart speaker company by the name of Sonos initiated a lawsuit against Google”
Would have expected it to also say “a search engine company called Google”

How many markets can Google enter and trivially kill?
I'm a fan of patent trolls being defeated, but Sonos is not a troll. They're being pushed and cajoled by the famgopolies. Both Apple and Google cloned their product, then Google started to shutter access to Google Play Music / YouTube Music.
Google is like a capricious god of ancient Greek mythology. It might seem friendly, but it takes what it wants and leaves dead, ruined corpses by the wayside.

The problem is that that's not how the patent system works. If the Sonos patent is upheld, it doesn't just stop google from making speakers that synchronize their clocks with each other over a local area network.[0] It stops literally everyone other than Sonos doing that, for 20 years since the patent was filed. Even lone engineers working in their garages. Even if they independently reinvent it, patent infringement doesn't require copying, or even knowledge that the original system or the patent existed. Even if synchronizing clocks is something any skilled distributed systems engineer would think of within 10s of deciding to design such a system.[1]
It gives sonos a monopoly over the entire idea, that they can enforce against the world.
It's like cheering a law that allows anyone who wore a violet shirt in the last month to be shot, because you know someone who wore a violet shirt who you think deserved it. Maybe, but laws apply to everyone, and you're poisoning the commons just to fuck over that one person.

[1] the mechanism claimed being obvious to someone skilled in the art should be a reason the patent is not valid, but US courts appear to have a history of making that difficult to prove.

Except the patent you link to doesn't sync the clocks.

I used to be 100% on board with you and totally agree.
The problem is that in today's world, a few players dominate the entire industry and can erase up and coming startups by simply pouring engineers and money into problems. Innovation can be copied on the cheap by these titans, leaving the hard working original inventor (companies with products and not trolls) with nothing to show.
Small companies with products (not trolls) need something to protect themselves against the giants. Because it certainly isn't a level playing field anymore.
Power is concentrated. Google and friends can't be the winners that take all.
I don't like patents. But there's no other way to survive when a giant wants to clone your product.

Maybe these had a bit of innovation in 2003 but there is nothing substantial. I'm sure some pre-network audio equipment had to synchronize state and audio timing so doing it over the LAN is not (IMO) sufficient for a new patent.
In any case, software patents should be very strict and last at most 5 years (which is more like 8 years from application to expiry).
