1312.2 (C) Space 2C: Prior Designs
Applicants should complete space 2C only if the claimed design revises, adapts, or rearranges a prior design. In such cases, space 2C should contain a clear description of the prior design with sufficient detail to distinguish the prior design from the new design, as well as a description of the revisions, adaptations, or rearrangements that resulted in the new design.
If the claimed design is not based on a prior design, applicants should leave space 2C blank.
