The entire point of a patent is the public disclosure of the mechanism of an invention for the exclusive right to market that invention. Therefore arguing that reverse engineering is a violation of a patent is definitionally incorrect. They should be arguing it's a violation of trade secrets. Of course, they'd lose on that argument too because clean room reverse engineering of a trade secret is fine because you definitionally don't have a patent on it!

It was a great place to work initially.\nAt one point I understood DL3 inside-out having implemented it on the GPU. I’ve mostly forgotten how it works now (but still remember enough to get me in trouble, so don’t ask). I never worked on the Linux driver, only the Windows one.\nThere were some reasonably smart people there. Some of my colleagues worked on the wireless adaptor for the HTC Vive VR headset just before I joined.\nDisplayLink was extremely protective of its IP, and Synaptics even more so, so this behaviour doesn’t really surprise me.\nAfter the acquisition there was multiple rounds of layoffs and it was no longer such a nice place to work. I regret staying as long as I did.\nPersonally, I’ve never felt the need to use one of our docks. In my home office, I have two displays connected to my Linux laptop, one via the HDMI port and the other via USB-C to HDMI. Then I just have a cheap USB hub that I keep my peripherals attached to.
