37 C.F.R. § 303.6 – Filing and delivery.

(a) Filing of pleadings—(1) Electronic filing through eCRB. Except as described in § 303.5(l)(2), any document filed by electronic means through eCRB in accordance with § 303.5 constitutes filing for all purposes under this chapter, effective as of the date and time the document is received and timestamped by eCRB.
(2) All other filings. For all filings not submitted by electronic means through eCRB, the submitting party must deliver an original, five paper copies, and one electronic copy in Portable Document Format (PDF) on an optical data storage medium such as a CD or DVD, a flash memory device, or an external hard disk drive to the Copyright Royalty Board in accordance with the provisions described in § 301.2 of this chapter. In no case will the Copyright Royalty Board accept any document by facsimile transmission or electronic mail, except with prior express authorization of the Copyright Royalty Judges.
(b) Exhibits. Filers must include all exhibits with the pleadings they support. In the case of exhibits not submitted by electronic means through eCRB, whose bulk or whose cost of reproduction would unnecessarily encumber the record or burden the party, the Copyright Royalty Judges will consider a motion, made in advance of the filing, to reduce the number of required copies. See § 303.5(j).
(c) English language translations. Filers must accompany each submission that is in a language other than English with an English-language translation, duly verified under oath to be a true translation. Any other party to the proceeding may, in response, submit its own English-language translation, similarly verified, so long as the responding party's translation proves a substantive, relevant difference in the document.
(d) Affidavits. The testimony of each witness must be accompanied by an affidavit or a declaration made pursuant to 28 U.S.C. 1746 supporting the testimony. See § 303.5(f).
(e) Subscription—(1) Parties represented by counsel. Subject to § 303.5(e), all documents filed electronically by counsel must be signed by at least one attorney of record and must list the attorney's full name, mailing address, email address (if any), telephone number, and a state bar identification number. See § 303.5(e). Submissions signed by an attorney for a party need not be verified or accompanied by an affidavit. The signature of an attorney constitutes certification that the contents of the document are true and correct, to the best of the signer's knowledge, information, and belief, formed after an inquiry reasonable under the circumstances and:
1. (i) The document is not being presented for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation;
2. (ii) The claims, defenses, and other legal contentions therein are warranted by existing law or by a nonfrivolous argument for the extension, modification, or reversal of existing law or the establishment of new law;
3. (iii) The allegations and other factual contentions have evidentiary support or, if specifically so identified, are likely to have evidentiary support after a reasonable opportunity for further investigation or discovery; and
4. (iv) The denials of factual contentions are warranted by the evidence or, if specifically so identified, are reasonably based on a lack of information or belief.
5. (2) Parties representing themselves. The original of all paper documents filed by a party not represented by counsel must be signed by that party and list that party's full name, mailing address, email address (if any), and telephone number. The party's signature will constitute the party's certification that, to the best of his or her knowledge and belief, there is good ground to support the document, and that it has not been interposed for purposes of delay.
(f) Responses and replies. Responses in support of or opposition to motions must be filed within ten days of the filing of the motion. Replies to responses must be filed within five days of the filing of the response.
(g) Participant list. The Copyright Royalty Judges will compile and distribute to those parties who have filed a valid petition to participate the official participant list for each proceeding, including each participant's mailing address, email address, and whether the participant is using the eCRB system for filing and receipt of documents in the proceeding. For all paper filings, a party must deliver a copy of the document to counsel for all other parties identified in the participant list, or, if the party is unrepresented by counsel, to the party itself. Parties must notify the Copyright Royalty Judges and all parties of any change in the name or address at which they will accept delivery and must update their eCRB profiles accordingly.
(h) Delivery method and proof of delivery—(1) Electronic filings through eCRB. Electronic filing of any document through eCRB operates to effect delivery of the document to counsel or pro se participants who have obtained eCRB passwords, and the automatic notice of filing sent by eCRB to the filer constitutes proof of delivery. Counsel or parties who have not yet obtained eCRB passwords must deliver and receive delivery as provided in paragraph (h)(2) of this section. Parties making electronic filings are responsible for assuring delivery of all filed documents to parties that do not use the eCRB system.
(2) Other filings. During the course of a proceeding, each party must deliver all documents that they have filed other than through eCRB to the other parties or their counsel by means no slower than overnight express mail sent on the same day they file the documents, or by such other means as the parties may agree in writing among themselves. Parties must include a proof of delivery with any document delivered in accordance with this paragraph.
