Q4. How can you file a plurality of designs?

Q4. How can you file a plurality of designs?

A4. An application may include a single design because Japan follows the one application-one design system.
Therefore, even if a plurality of different designs are directed to the same article and are similar to one another, they must be filed as separate applications (Art. 7). However, as an exception, in the case of designs of articles where two or more articles are used together and the designs of those articles are unified, those designs can be filed in a single application as a Design for a Set of Articles (Art. 8).
Examples: a dinner set; a coffee set; a set of knife, fork and spoon.
