2116.6 Verification of Copyright Notice
Generally, renewal registration of a published work is premised on these facts:
• The full original term of copyright was secured upon first publication with the statutory or U.C.C. notice (or soon thereafter by securing ad interim copyright, during which the work was manufactured and published in the United States with the required copyright notice); and
• Statutory copyright has been maintained uninterrupted through the full original term and into the renewal term, and subsists at the time of renewal registration.
The U.S. Copyright Office requires written verification of these facts by a knowledgeable source. For information about notice requirements under the Copyright Act of 1909, see U.S. COPYRIGHT OFFICE, COMPENDIUM OF U.S. COPYRIGHT OFFICE PRACTICES Chs. 4, 8.2, & Supplementary Practice Nos. 18, 19, 27, 29, 35 & 37 (1st ed. 1973), available at http://copyright.gov/comp3/chap2100/doc/appendixA-noticerequirements.pdf. Regarding the notice requirements for specific classes of works, see Part IV.
