1212.1 (C) Title for More Than One Mask Work Given

1212.1 (C) Title for More Than One Mask Work Given


Only one mask work may be registered on a single application form with one set of chips. However, in cases where the mask works are substantially identical (i.e., the differences are de minimis), the U.S. Copyright Office will allow applicants to refer to substantially identical mask works in the “Additional Information” space of Form MW/CON (a continuation form for Form MW). For example, the applicant may state “Mask work substantially identical to those contained in [titles of other mask works].”


The deposit, however, must be limited to the single mask work identified in space 1 (i.e., only one set of visual representations, and one set of four chips).
