What is the importance of ‘nexus’ in commercial success arguments for patents?

‘Nexus’ is crucial in commercial success arguments for patents as it establishes a direct link between the claimed invention and its market success. The MPEP 716.03 states:

The term ‘nexus’ designates a factually and legally sufficient connection between the evidence of commercial success and the claimed invention so that the evidence is of probative value in the determination of nonobviousness.

Without a proven nexus, commercial success evidence may be deemed irrelevant to patentability. To establish nexus:

  • The success must be directly attributable to the unique characteristics of the claimed invention.
  • Applicants must show that the success is not due to other factors like marketing, prior art features, or business acumen.
  • The commercially successful product must embody the claimed features.

A strong nexus can significantly strengthen an argument for non-obviousness, making it a critical component in overcoming patent rejections based on commercial success.
