Virtual patent marking

EXFO’s products and services are protected by patents in the United States of America and elsewhere in the world.

This Virtual Patent Marking list associates products and services with US applications, publications, and/or design and utility patents ("properties") and is posted on the Internet to provide notice to the public of the properties listed. There is no charge for accessing this publicly available information. This list is provided in compliance with the virtual patent marking provisions of 35 U.S.C. § 287. Non-US patents are not listed. The products listed below are manufactured directly or indirectly by EXFO Inc., its Affiliates, Licensees or Successors in Interest.

The patent process is dynamic and the content of this list and association between products and services and properties may change due to events including, but not limited to: filing, publication, issuance, licensing, product changes, expiration, abandonment, and other circumstances. The content of this list is updated from time to time but may not be up to date at the specific time you visit this link. Patent applications may be pending or published and patents may have issued in the United States which are not identified on this list. This list might not be all inclusive and other products not listed here may be associated with one or more properties in the United States or elsewhere. Furthermore, additional patent may be pending or granted in the United States and elsewhere. Absence of any property from this list does not prevent enforcing any and all legal rights associated with the property. If we do not specifically identify a product on this web site or do not otherwise mark it with a patent number, then we are not currently marking it. This list may be unavailable from time to time without notice as part of maintenance or an unintended outage. Efforts will be made to maintain this link page active.
