My good friend Google pulled this result from A71 thread a few months ago…
“wine was the original purchaser who then sold to jacobs. jacobs would have been safe from repossession had mjc not filed to perfect the security interest. This is because by filing, mjc put all on notice there was a security interest. Note that mjc did not need to file to perfect; however, by doing so, they preserved their rights against second hand consumers like jacobs. This falls under the “garage sale” rule.
you are correct that a buyer in ordinary course of business is protected against perfected security interest. A buyer in ordinary course of business is protected against the seller's supplier attempting to repossess goods. For ex, if you buy a tv from best buy, and best buy screwed samsung over, samsung cannot come to your house and repossess your tv bc you were a buyer int he ordinary course of business.”
So basically…garage sale rule.
