I had to look up Collateral Estoppel, so.
#TIL about Non-Mutual-Defensive #CollateralEstoppel where by "a defendant attempts to prevent a plaintiff from re-litigating an issue that was previously decided against the plaintiff in another lawsuit against a different party."

To put it another way, if Mr. Denke's defense was successful, and ruled on in his case, then Monster Cable couldn't attempt to use that failed issue against a different cable manufacturer when Monster Cable sued them for alleged Patent and Trade dress infringement.
