Yeah I mean…everyone who’s been buying stainless off the shelf has been getting taken for a ride by these CLS manufacturers. The labs who built their own systems piecewise and got engineers to stamp the designs … Those guys are gonna remain under the radar. My last lab in Oregon basically built their own CLS and satisfied the fire marshall, so they’re simply not on a client list and the equipment they’re operating is trade secret. The patentee will literally never have the means of becoming aware of them. This is maybe more common in larger industries that have teams of engineers and PEs on staff.
Fwiw, I don’t necessarily think the patent holds up when you consider how much prior art their is and it’s lack of novelty. One standard/legal precedent for something being direct infringement is that the infringement has to be pretty much spot on to the claims made in the patent…so even small deviations from the patent would make a device novel enough to not be infringement. My joke is - just throw a clock on it and suddenly it’s novel.
