If there is a patent on some part of CAN (and it sounds like there is),
then it doesn't matter whether you reverse engineer something or build
it from publically available documentation. Even when you've never
heard of CAN before and reinvent it, the patent still applies.
After all, it's the whole point of a patent to encourage publication of
technological methods (in exchange for protection of the invention).
Designing to spec doesn't circumvent it.
