#Submitting a Takedown Notice

A valid notice under 17 U.S.C. § 512(c)(3) must include all of the following:

1. A physical or electronic signature of the copyright owner (or a person authorized to act on behalf);
2. Identification of the copyrighted work claimed to have been infringed;
3. Identification of the material that is claimed to be infringing and that is to be removed, with information reasonably sufficient to let us locate it (URL or screenshot with context);
4. Your contact information (address, telephone number, email);
5. 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, its agent, or the law;
6. A statement, made under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorized to act on the owner's behalf.

Notices that do not substantially comply may be invalid.

#Our Response

On receipt of a valid notice we will:

• Remove or disable access to the allegedly infringing material expeditiously;
• Take reasonable steps to notify the user who posted it;
• Provide that user with a copy of the notice.

#Counter-Notices

A user whose content has been removed may submit a counter-notice that includes:

1. A physical or electronic signature;
2. Identification of the material removed and its former location;
3. A statement under penalty of perjury that the user has a good-faith belief that the material was removed by mistake or misidentification;
4. The user's name, address, and telephone number;
5. A statement that the user consents to the jurisdiction of the U.S. District Court for the Northern District of California (or, if outside the U.S., any judicial district in which MathRhythm may be found) and will accept service of process.

On receipt of a valid counter-notice, we will forward it to the original complainant. If the complainant does not file a court action within 10–14 business days, we may restore the removed content.

#False Claims

Under 17 U.S.C. § 512(f), any person who knowingly materially misrepresents that material is infringing, or was removed by mistake, may be liable for damages and attorneys' fees.

#Repeat Infringers

In accordance with 17 U.S.C. § 512(i), MathRhythm terminates, in appropriate circumstances, accounts of users who are repeat infringers. "Repeat infringer" means any account with three or more substantiated takedown notices against distinct content within any 12-month period, unless we determine in good faith that termination is inappropriate.
