Information for IACT users


IACT provides certain key benefits that make arbitration before IACT a desirable path, including:


  • IP Focus. IACT is well-suited to resolving international disputes involving standard essential patents.

  • 1-Year Time Limit.  Each resolution will proceed with a one-year time limit from the formal initiation (ex. an appointment of the third arbitrator) unless otherwise agreed by the parties.


  • Global coverage.  Arbitrators and mediators are selected from major jurisdictions around the globe. The parties select and mutually agree to the arbitrators or mediator.  In the event that the parties cannot agree, upon notice, the IACT administration will select or complete the selection with arbitrators from jurisdictions separate from the parties or the prior selections.

  • Unparalleled Experience. Most arbitrators have presided over thousands of complicated cases as a judge, or have handled legislation as a director. Our experts have developed the current Intellectual Property law in each jurisdiction.


  • Cost efficiency.  IACT seeks to achieve cost efficiency by charging the arbitrators' hourly rates for time actually spent on the dispute, rather than using other commonly-used fee amounts such as a percentage of the amount in controversy. Although individual arbitrators' rates may vary, the benchmark arbitrator rate will be approximately 1,000 USD per hour.

  • Appeal. In conjunction with the panel’s decision, the parties will have the opportunity to point out any major prejudicial errors to a supervisory panel composed of arbitrators from each of the five primary regions (China, Japan, Korea, U.S., and Europe). This may include a chance to make a brief oral presentation.​​
