JP Helder's Experience

Trial and Litigation Experience

JP has substantial experience trying complex business cases to juries. His jury trial experience includes cases with amounts in controversy in the hundreds of millions of dollars. The following cases illustrate this experience:

Atchison Casting v. Dofasco. JP was co-lead counsel in a major jury trial in federal court in Kansas City, Kansas. The plaintiff, Atchison Casting Corporation, was represented by the noted tobacco defense firm, Shook, Hardy & Bacon. JP, then with Sonnenschein, represented the defendant Dofasco, the second-largest steel company in Canada. The case involved a transaction for the sale of intellectual property and related assets in the steel foundry and locomotive manufacturing industries. The plaintiff sought in excess of $50 million in actual damages and unspecified punitive damages. JP cross-examined 7 of the 10 witnesses in the plaintiff's case, including all experts. JP put on 5 of the 9 witnesses in the defendant's case, including all experts, and gave the final 30 minutes of the closing argument. The jury entered a verdict for the client Dofasco on all counts but one, and on that count awarded the plaintiff no damages.

ADI Business Systems v. Lanter Company. JP represented Lanter Company in a federal jury trial in Kansas City, Missouri. This case involved an alleged oral agreement not to compete for trucking business from the American Italian Pasta Company. The plaintiff, ADI Business Systems, Inc., sought in excess of $3.5 million, though much of those damages were stricken by the Court during the course of the trial. The jury returned a verdict in favor of Lanter.

American Central East Texas Pipeline Company v. Duke Energy Resources. JP handled significant parts of a multi-faceted, multiparty antitrust case on behalf of Duke Energy Corp. and various of its subsidiaries pending in the United States District Court for the Eastern District of Texas. The first phase of this case, brought by American Central Eastern Texas Pipeline Company, involved alleged claims for illegal monopolization under Section 2 of the Sherman Act. Those claims, together with various tort claims, were referred to arbitration in Dallas, Texas. The arbitration occurred in June and July of 2000, and in this phase, American Central was represented by Houston's Susman Godfrey firm. American Central sought damages from Union Pacific Resources Company and structural/injunctive relief from subsidiaries of Duke Energy Field Services, Inc. JP handled all of the experts for Duke, including cross-examination of the plaintiff's economists. While the arbitrator did award damages against Union Pacific, the arbitrator refused to award the injunctive relief sought against JP's client, Duke.

The second phase of the antitrust case was tried to a jury in federal court in Marshall, Texas in February and March of 2001. The Furth Firm of San Francisco and McKool Smith of Dallas represented American Central in these proceedings. The codefendants settled during the course of the trial, which ended the jury phase of the case. Duke did not settle and no relief was awarded from Duke. The third phase of this case was tried in Tyler, Texas in August of 2001 and involved Section 1 Conspiracy claims, as well as Section 2 refusal to deal claims. The refusal to deal claims were referred back to arbitration (the fourth phase) and were tried in December 2001 and January of 2002. On the Section 1 conspiracy claims, the Judge found in favor of Duke. In the arbitration, American Central was granted certain contractual relief, but was refused the divestiture it sought.

JP has also been involved in major cases that have settled, including a major antitrust case for Duke Energy's then-subsidiary, the Panhandle Eastern Pipe Line Company. The plaintiffs were a number of affiliated pipe line companies operating as the Kansas Pipeline Operating Company. They sued Panhandle alleging federal antitrust claims for monopolization, as well as tortious interference with business expectancy. Plaintiffs sought in excess of $300 million. JP took and defended the depositions of the experts, and most fact witnesses. The case was settled after the completion of all discovery.

Formula One Licensing, B.V. v. Limited. JP represented Limited and related entities in antitrust, trademark and cybersquatting claims against Formula One Licensing, Formula One Management and the FIA in federal court in San Francisco. Formula One Management claimed that was infringing its marks by using that internet address and covering the sport without authorization. alleged that Formula One Management and the FIA were violating Sections 1 and 2 of the Sherman Act in their efforts to monopolize the sport and put out of business. The case was settled in January of 2002. As part of the settlement, was sold to Formula One Management. With London co-counsel, JP handled that transaction.
