Abstract: fair use of a registered trademark does not constitute infringement, but users shall both have no intent to infringe and accord with the objective facts. The court facing those cases shall apply  Trademark Law to consider the original intention of Trademark Law instead of applying a rigid formula to determine that the infringement shall rely on “whether the results cause confusion”．
