Using DDQX materials, requesting permission, and reporting an intellectual-property concern.
DDQX Learning Institute, Inc., a Delaware C-corp doing business in Arizona and operating as DDQX Learning, owns or holds rights to its original teaching materials, text, graphics, videos, reports, and other protectable content, unless identified otherwise. Third-party materials remain the property of their respective owners.
Purchasing or accessing material does not transfer ownership. Unless another license is stated, access is licensed for the named learner’s personal educational use under our Terms of Use.
Do not resell, publicly redistribute, or commercially reproduce protected DDQX material without permission. These restrictions do not remove uses permitted by law, applicable copyright exceptions, or rights in general knowledge and unprotected ideas.
DDQX Learning, DDQX Learning Institute, the DDQX logo, and DDQX’s named educational methods identify DDQX’s services. Do not use a DDQX name or mark in a way that falsely suggests sponsorship, affiliation, or endorsement.
Third-party names and marks identify their respective products, services, examinations, and organizations. Their appearance in educational material does not imply that their owners endorse DDQX. A trademark symbol is not a statement that a particular mark is federally registered.
Email info@ddqxlearning.org to request permission to reproduce, adapt, distribute, or commercially use DDQX material. Identify the material, proposed use, audience, format, and distribution method.
Written permission applies only to the scope granted. Silence or receipt of a request does not grant permission.
Send concerns to DDQX Learning — Copyright Contact at info@ddqxlearning.org, or call 480-648-4049 for help routing a notice. General written correspondence may be sent to
PO Box 416Identify the work you believe is protected, the material you believe infringes it, and the exact page or location. Include your contact information and explain whether you are the rights holder or an authorized representative. Do not include unrelated personal information.
DDQX will review a sufficiently specific complaint and may remove or restrict access while evaluating it. Where appropriate, we notify the person who supplied the material and provide an opportunity to respond. Copyright notices are legal communications and may be shared with the affected contributor or relevant provider to resolve the complaint.
When a notice is submitted under the Digital Millennium Copyright Act, it must meet the applicable statutory requirements. These include a physical or electronic signature; identification of the copyrighted work; information sufficient to locate the challenged material; and contact details for the rights holder or authorized representative.
The notice must state a good-faith belief that the disputed use is not authorized by the rights holder, its agent, or law. It must also state that the notice is accurate and, under penalty of perjury, that the sender is authorized to act for the owner of the exclusive right involved.
The contact above is DDQX’s route for copyright complaints. This page does not claim that DDQX has registered a designated DMCA agent or qualifies for a particular statutory safe harbor. Any formal designated-agent information separately published and registered for the relevant service controls the routing of notices to that agent.
If your material was removed because of a mistake or mistaken identification, you may contact us to request review. Where the DMCA counter-notice process applies, include your signature, name, address, telephone number, the removed material and its former location, and a statement under penalty of perjury of your good-faith belief that removal resulted from mistake or misidentification.
A qualifying DMCA counter-notice must also consent to jurisdiction of the appropriate United States federal district court and to acceptance of service from the original notice sender or its agent. For an address outside the United States, the required consent concerns a district where the relevant service provider may be found.
Where the statutory process applies, a qualifying counter-notice is forwarded to the claimant and restoration follows the statutory 10-to-14-business-day process unless the required notice of court action is received. Other independent grounds for restricting material may still apply.
DDQX may suspend or terminate accounts for repeated infringement in appropriate circumstances. Knowingly making a material misrepresentation in an infringement notice or counter-notice can create legal liability.
