Hmmm, still not sure I buy it. If I bought a Craftsman snowblower in 1985 and sold it on Craig’s List in 2018, advertising it as a 1985 Craftsman snowblower, I mentioned a trademark name. I still have done anything wrong or anything that doesn’t happen a million times a day. I’d make the same argument for reselling a car, gun, appliance, whatever. I still want to understand how this KK case is any different.
1 shot sale vs establishing a business. The difference is repetition. If you setup a booth at the swap meet where you’re reselling Craftsman products with their logo on display every weekend you are violating their trademark.
