Ourph said:It's not even that. The court case was a case over contract violations, not trademark. The contract concerned the use of trademarks, but the points of contention were all concerning whether Mayfair was violating the contract they agreed to, not whether they had the right to indicate compatibility with AD&D in the first place.
IIRC,in dicta the judge actually indicated that he thought indication of compatability/suitable for use with was probably OK, but that was not the issue before him. It was the terms of the agreemnt.
