Synaptics patent claims stop work on DisplayLink drivers(lwn.net)

I finally upgraded all my gear to USB3.1Gen2+ so I no longer need to use DisplayLink. It's so nice. No more messing around with weird broken drivers. I just plug things in and they work.

It’s also disturbing they have the gall to demand tens of thousands of dollars for the task of specifying which of their 100+ maybe relevant patents he’s infringing.

Does UK patent law somehow work differently?

> The letter continued to claim that Lothian would be "single-handedly eviscerating DisplayLink's competitive advantage in this crowded market by educating our competitors and other third parties as to how we implement our proprietary technology"

If one guy can reverse-engineer everything with an LLM and some free time, I'm pretty sure their competitors can as well, and they won't be doing it out in the open like this guy was...

this is a good point. Isn't one of the pre-conditions for a patent (in the US at least, this case was UK) that it be "non-obvious" ? If LLMs can shit out working solutions that infringe patents, or "trivially" reverse engineer protocols, I wonder if we will see challenges in court that it was "obvious" to ask the LLM, and therefore the patents were trivial and therefore should be invalidated?

That seems to be a separate claim unrelated to their patent claims. Patents themselves are required to have all of the information that would allow someone to implement what is in the patent. Of course, there could be many ways to implement it. And a specific implementation could be further protected by trade secrets. The part that would be a trade secret is inherently not in the patent.

You have to wonder if this part was approved by a qualified lawyer at all. A trade secret would describe proprietary knowledge of how to implement the technology, but would have no protection under patent law.

They also repeatedly claimed "DisplayLink is not a member of OIN" when it actually is, and later when they acquiesced to the cease and desist, one of the actual engineers from the company tried to review the PR to ask for changes. It's not clear anyone there has any clue what's going on!

You're saying I can't use a shell company acquisition as a means to shield certain technologies from my other agreements? Booo

I suspect they know that, but it reads as if they were just lazily tacking that claim on for effect. This isn't a petition to a court, this is just a demand letter. Listing out a bunch of scary damages is how demand letters often work. They don't have to go into details as to the basis of their legal claims.

I wish Synaptics a very "find this work fully completed by someone on https://gitflic.ru/" day.

At some point there needs to be a test of when software is related to owning hardware.

Some questions that come to mind are:

Do you actually own the hardware?

Do you stop owning the hardware, meaning you're not allowed or able to use it once the company that's sold it to you stops providing or updating hardware?

Does every piece of hardware come with a guarantee that it will work on every piece of hardware that it's attached to forever?

These are just a few of the really troubling questions when people forget that software has to run on hardware. And the closer the software is to the core operation of a piece of hardware and equipment, the more topics like right to repair or right to maintain or right to optimize come up.

I never thought that a video card replacement driver would make me think of companies that are limiting Farmers from repairing and updating their own tractors.

If you want to know whether any relatively modern computer hardware is encumbered by IP restrictions, it's pretty simple, the answer is yes.

The closest you can get is something like the Raptor Talos II, although parts of the hardware are still under patent.

Which is made funnier by the lawyer's name being Bateman. Sorry, could not resist that one.

What I find more ridiculous is the timing:

> You are to provide Synaptics, no later than 11:59 p.m. Pacific Time on October 11, 2026

The letter is dated "October 5, 2026". WTF are these lawyers smoking that they think 5 days is any reasonable time frame.

They just try to keep the pressure up so that the other entity gives up before they have time to estimate whether any of the claims are valid. One person against big corporation, which is threatening with big penalties. A common tactic.

Unbelievable mafia tactics from those clowns.

Seriously, use OCuLink. It costs $15 for the pcie card, $10 for a cable, and $100 for a GFX card dock, and a PSU.

OCuLink doesn't even use drivers. It's literally just a PCIE passthrough. All usual tools apply, whereas DisplayLink encrypts all data, so a big fuckyou for getting logs.

Quit giving trash companies pounds of money for abuse at scale.
