Excluding claims for injunctive or other equitable relief, for claims related to the Coursera Sites where the total amount sought is less than ten thousand U.S. Dollars ($10,000.00 USD), either Coursera or You may elect at any point during the dispute to resolve the claim through binding, non-appearance-based arbitration. The dispute will then be resolved using an established alternative dispute resolution ("ADR") provider, mutually agreed upon by You and Coursera. The parties and the selected ADR provider shall not involve any personal appearance by the parties or witnesses, unless otherwise mutually agreed by the parties; rather, the arbitration shall be conducted, at the option of the party seeking relief, online, by telephone, online, or via written submissions alone. Any judgment rendered by the arbitrator may be entered in any court of competent jurisdiction.

If you believe in good faith that materials on the Coursera Sites infringe your copyright, you (or your agent) may send us a notice requesting that the material be removed, or access to it blocked.

The notice must include the following information: (a) a physical or electronic signature of a person authorized to act on behalf of the owner of an exclusive right that is allegedly infringed; (b) identification of the copyrighted work claimed to have been infringed (or if multiple copyrighted works located on the Site are covered by a single notification, a representative list of such works); (c) identification of the material that is claimed to be infringing or the subject of infringing activity, and information reasonably sufficient to allow Coursera to locate the material on the Site; (d) the name, address, telephone number, and email address (if available) of the complaining party; (e) a statement that the complaining party has a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law; and (f) a statement that the information in the notification is accurate and, under penalty of perjury, that the complaining party is authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.

Notices must meet the then-current statutory requirements imposed by the DMCA; see http://www.loc.gov/copyright for details. Notices and counter-notices with respect to the Site should be sent to:

We suggest that you consult your legal advisor before filing a notice. Also, be aware that there can be penalties for false claims under the DMCA.
