So, the Chinese broke the law, not the refurbisher. And yet, it is the refurbisher that got sued here. I've seen similar things happen with Bosch vs Porsche, where Porsche parts retail for a fairly large multiple of the Bosch parts, the only difference being the Porsche logo. Functionally equivalent, made in the same factory, to all intents and purposes the same part.

Manufacturers that want to distinguish themselves by labeling commodity parts with their trademarks are not doing this with the intention of protecting their customers, they are protecting their bottom line.
