Hitachi Metals Wins Appeal in Landmark Antitrust Ruling by China’s Supreme People’s Court

The expert testimony behind one of the few antitrust cases to appear before China’s Supreme People’s Court (“SPC”).

In December 2014, four Chinese producers (“plaintiffs”) of sintered neodymium-iron-boron (“NdFeB”) magnets alleged that Hitachi Metals, a leading producer of magnetic materials headquartered in Tokyo, had abused its dominant position in the patent licensing market for the sintered NdFeB essential patents held by Hitachi Metals by refusing to license patents to the plaintiffs. In the first instance judgment, the Ningbo Intermediate People’s Court sided with the plaintiffs. Hitachi Metals appealed the decision and brought the matter to the SPC in July 2021.

FTI Consulting’s subsidiary Compass Lexecon was retained by Hitachi Metals to provide expert reports and testimony.

On December 14, 2023, the SPC completely overturned the first instance verdict of the lower court, finding that Hitachi Metals did not abuse its market dominance.

Applying expert economic analysis to competition concerns

Compass Lexecon’s Executive Vice President Dr. Vanessa Yanhua Zhang was retained by Hitachi Metals to provide expert reports and testimony in the appeal.

  1. Dr. Zhang testified that the relevant product market, in this case, should be the technology market of sintered NdFeB magnets, rather than the narrower patent licensing market for the sintered NdFeB essential patents owned by Hitachi Metals.

  2. Dr. Zhang further testified that Hitachi Metals did not have a dominant position in the relevant market and therefore its actions did not constitute an abuse of market dominance.
