"Retro" Designs: Using Your Utility Portfolio to Expand Design Protection


From gadgets to apparel, retro is all the rage these days. What does this mean for your consumer product patent portfolio?

The obvious strategy is to consistently file design applications covering your product releases, so you’re always covered. But what about products that didn’t have the design interest or IP budget at the time of release, but that are now popular and being knocked off? One strategy is to mine your pending US utility portfolio for the design. A US design application can be filed as a continuation of a utility application. So long as the design is fully supported in an old pending utility application, you should be able to turn that into a viable design application.

Nothing new with “retro”

Design applications are subject to the same conditions as utility applications when it comes to claiming priority under 35 USC § 120.[i] Chief among these conditions may be the requirement that the design claimed be disclosed in the parent utility application in a manner sufficient to satisfy the written description requirement of § 112. Depending on the nature of the design, this may be satisfied by at least a few good-quality, clear, and consistent views of the design, whether line drawings or photographs.

In preparing the drawings for your design continuation, do not stray from the utility disclosure. It is generally acceptable to “formalize” the drawings by removing reference numbers and drawing the design more clearly. Anything more requires a case-by-case review of the whole disclosure to ensure that any new view or detail is completely disclosed in the parent application in the manner required by § 112, otherwise you risk a new matter rejection during prosecution.

Designs are different than utility applications, so keep these points in mind:
