Representative Cases

  • Soleiman Professional Dental Corp. v. Pacific Dental Services, LLC; Case No. 20STCV42885 (LA Superior Court) – Ms. Brantly and KBS represent a periodontist group in a lawsuit against a dental service organization asserting state antitrust claims. The case is now in discovery.
  • Beckman Coulter, Inc. v. Quidel Corp., (San Diego Super. Ct.) – Ms. Brantly and Mr. Stockinger represented Defendant Quidel Corp. in this antitrust case brought under California’s Cartwright Act and Cal. Bus. & Prof. Code Section 16600. Beckman alleged that a provision placing restrictions on sales of testing products related to the diagnosis of congestive heart failure in a contract between Beckman and Quidel is an illegal non-compete and unreasonably restrains trade. After the trial court granted summary judgment on Beckman’s Section 16600 claim, the Court of Appeals reversed and the California Supreme Court granted certiorari. The California Supreme Court ultimately transferred the case back to the lower courts after ruling in Ixchel Pharma LLC v. Biogen, Inc., 9 Cal. 5th 1130 (2020), that a non-compete clause between businesses is subject to a rule of reason analysis.
  • Dane S. Field, Trustee of the Bankruptcy Estate of Aloha Sports Inc. v. The National Collegiate Athletic Ass’n (Haw. Circuit Court) – Ms. Brantly and David Kesselman represented Aloha Sports in this case brought under Hawaii’s state antitrust statute arguing that the NCAA unfairly decertified the Seattle Bowl in order to disrupt a sale of Aloha Sports. Ms. Brantly successfully argued to the Hawaii Supreme Court that summary judgment should not have been granted on Aloha Sport’s Hawaiian state law antitrust claim against the NCAA. The opinion clarified the proof necessary for a plaintiff to succeed on an antitrust claim under Hawaii law. In a unanimous, 39-page, published opinion, the Supreme Court held that the lower courts erroneously required Aloha Sports to prove that the NCAA – while engaging in an unfair method of competition resulting in injury to Aloha Sports – actually harmed competition. The Hawaii Supreme Court also reaffirmed that a plaintiff may generally describe the relevant market without resort to expert testimony. A copy of the opinion can be found at http://www.courts.state.hi.us/wp-content/uploads/2018/11/SCWC-15-0000663.pdf. The Supreme Court remanded the case to the circuit court for trial.
