Mr. Berryman's representative matters include:

Trade Secrets and Unfair Competition

  • Requiring a competitor of our Fortune 100 manufacturer client to redesign its product line, based on engineering designs reviewed and approved by our client, and following discovery in trade secret and copyright infringement litigation.
  • Filing trade secret and Lanham Act litigation on behalf of a toy manufacturer and ultimately requiring competitor to alter competing product designs, notify customers, and modify advertising materials and website.
  • Partnering with the FBI and United States in presenting claims involving the theft of key company trade secrets and intellectual property.
  • On several occasions, successfully retrieving and stopping the proliferation and use of company trade secrets taken by former employees to new places of employment.

Distribution and Supply Chain

  • Winning an arbitration against a distributor of our software developer client who alleged entitlement to hundreds of thousands of dollars in unpaid commissions pursuant to a contract between the parties.
  • Arguing before the Wisconsin Supreme Court regarding whether Wisconsin should adopt the United States Supreme Court's decision in Brooke Group v. Brown & Williamson Tobacco Group, 509 U.S. 209 (1993), which established the requirements for proving a predatory pricing antitrust claim; whether the stringent standard governing the admissibility of expert testimony set forth in Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993), affects the applicability of Brooke Group to Wisconsin law; and whether Wisconsin should adopt the concept of federal disaggregation of damages.
  • Successfully resolving claims against our Fortune 100 client asserting a group boycott and restraint of trade in violation of Section 1 of the Sherman Act; following 50 depositions and significant economic expert work, we wrote the summary judgment brief resulting in a settlement for less than the cost of defense.

Contract Litigation

  • Winning an arbitration against a former CEO of our high-tech manufacturing client who alleged entitlement to significant proceeds based on an earn-out provision.
  • Convincing a federal District Court to overturn a $32 million default entered (prior to the firm's retention) against a product manufacturer client, following a week-long, multiparty mediation failing to result in settlement.
  • Defending a Fortune 100 diversified manufacturer in business litigation, including antitrust, product distribution, contract, and trade secret litigation pending in several state and federal courts.
