As a Subscriber, you may not store, distribute or otherwise disseminate any material or content over the Optimum Online Service in any manner that constitutes an infringement of third party intellectual property rights, including but not limited to copyrights. Pursuant to the Digital Millennium Copyright Act ("DMCA") and other applicable laws, Altice reserves the right, in its sole discretion, to suspend or terminate, in appropriate circumstances, the Optimum Online Service provided to any Subscriber who Altice reasonably believes to be infringing third-party copyright or other intellectual property rights, including repeat infringers. This policy is in addition to and does not affect or modify any other rights that Altice may have under law or contract.

If a copyright holder believes in good faith that materials being hosted by Altice or otherwise stored on its network infringe on its rights, the copyright holder (or its agent) may send Altice a notification in accordance with the requirements set forth in the DMCA, requesting that Altice remove or block access to the infringing material. The notification must be sent to:

All notifications sent to Altice by the copyright holder must be in writing and include the following:

  1. A physical or electronic signature of a person authorized to act on behalf of the owner of an exclusive right that is allegedly infringed;
  2. Identification of the copyrighted work claimed to have been infringed, or if multiple copyrighted works at a single on-line site are covered by a single notification, a representative list of such works at that site;
  3. Identification of the material that is claimed to be infringing or to be the subject of infringing activity and that is to be removed or access to which is to be disabled, and information reasonably sufficient to permit Altice to locate the material;
  4. Information reasonably sufficient to permit Altice to contact you, such as an address, telephone number, and if available, an electronic mail address at which the complaining party may be contacted;
  5. A statement that the copyright owner or its agent 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
  6. A statement that the information in the notification is accurate, and under penalty of perjury, that you are authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.

Upon receipt of a written notification that is compliant with the above terms, Altice will respond promptly to remove or disable access to the material alleged to be infringing. Altice will also take reasonable steps to promptly notify the affected Subscriber that we have removed or disabled access to that material.

If as a Subscriber, you receive a notification of copyright infringement from Altice, pursuant to the DMCA you may file a counter notification to Altice. Upon receipt of a counter notification that satisfies the requirements of the DMCA, Altice will provide a copy of the counter notification to the copyright holder who sent the original notification of claimed infringement and will follow the DMCA's procedures with respect to a received counter notification. In all events, Subscriber agrees that Altice will not be a party to any dispute or lawsuit regarding alleged copyright infringement.
