DALLAS — In an intellectual property suit he characterized as “devoid of civility and professional conduct,” a federal judge denied a defense motion to shift costs to the plaintiff.

U.S. District Senior Judge Royal Furgeson ruled on January 3 in M3 Girl Designs LLC v. Blue Brownies LLC that “both sides are not guiltless in regard to civility issues,” but that defense attorney Charles Hanor’s conduct was “in question” because the motion was filed by the defendants, who had secured a take-nothing judgment.
