What is the structure of a Jepson Claim?

The structure of a Jepson claim is characterized by its distinct format, which includes a preamble that details the old art followed by a description of the new invention. This format is particularly useful in patent applications as it establishes a clear distinction between what is already known in the prior art and what is being claimed as a novel aspect of the invention.

The preamble serves to acknowledge the existing technology, thus framing the new invention in context and highlighting its advancements or differences. By laying out the prior art first, the Jepson claim allows the inventor to emphasize the improvements or novel features that distinguish their invention from what is already available. This format can be beneficial in overcoming rejections based on prior art, as it explicitly addresses the limitations of existing solutions and showcases the inventive step.

In contrast, other formats do not incorporate this specific structure of recognizing the prior art upfront, and they may not provide the same clarity in presenting the innovation's context and significance when compared to what already exists.
