DMCA policy

This Digital Millennium Copyright Act policy ("Policy") applies to the docbrown.info website ("Website" or "Service") and any of its related products and services (collectively, "Services") and outlines how this Website operator ("Operator", "we", "us" or "our") addresses copyright infringement notifications and how you ("you" or "your") may submit a copyright infringement complaint.

Protection of intellectual property is of utmost importance to us and we ask our users and their authorized agents to do the same. It is our policy to expeditiously respond to clear notifications of alleged copyright infringement that comply with the United States Digital Millennium Copyright Act ("DMCA") of 1998, the text of which can be found at the U.S. Copyright Office website.

What to consider before submitting a copyright complaint

Please note that if you are unsure whether the material you are reporting is in fact infringing, you may wish to contact an attorney before filing a notification with us.

The DMCA requires you to provide your personal information in the copyright infringement notification. If you are concerned about the privacy of your personal information, you may wish to hire an agent to report infringing material for you.

Notifications of infringement

If you are a copyright owner or an agent thereof, and you believe that any material available on our Services infringes your copyrights, then you may submit a written copyright infringement notification ("Notification") using the contact details below pursuant to the DMCA by providing us with the following information:

- Identification of the copyrighted work that you claim has been infringed, or, if multiple copyrighted works are covered by this Notification, you may provide a representative list of the copyrighted works that you claim have been infringed.
- Identification of the infringing material and information you claim is infringing (or the subject of infringing activity), including at a minimum, if applicable, the URL or URLs of the web pages where the allegedly infringing material may be found.
- Information reasonably sufficient to permit us to contact you, such as an address, telephone number, and, if available, an e-mail address.
- A statement that you have a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, the copyright owner's agent, or the law.
- 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.
- A physical or electronic signature (typing your full name will suffice) of the copyright owner or a person authorized to act on their behalf.

All such Notifications must comply with the DMCA requirements. You may refer to a DMCA takedown notice generator or other similar services to avoid making mistake and ensure compliance of your Notification.

Filing a DMCA complaint is the start of a pre-defined legal process. Your complaint will be reviewed for accuracy, validity, and completeness. If your complaint has satisfied these requirements, our response may include the removal or restriction of access to allegedly infringing material.

If we remove or restrict access to materials or terminate an account in response to a Notification of alleged infringement, we will make a good faith effort to contact the affected user with information concerning the removal or restriction of access.

Notwithstanding anything to the contrary contained in any portion of this Policy, the Operator reserves the right to take no action upon receipt of a DMCA copyright infringement notification if it fails to comply with all the requirements of the DMCA for such notifications.

The process described in this Policy does not limit our ability to pursue any other remedies we may have to address suspected infringement.

Changes and amendments

We reserve the right to modify this Policy or its terms relating to the Website and Services at any time, effective upon posting of an updated version of this Policy on the Website. When we do, we will revise the updated date at the bottom of this page.

Reporting copyright infringement

If you would like to notify us of the infringing material or activity, you may send an email to chem55555@hotmail.com.
