What is the nexus requirement in patent obviousness?

Nexus links your objective indicia evidence—like sales or praise—directly to the claimed invention. Without it, evidence gets tossed, even mountains of it.

Why did MRI lose their display cooling patents?

PTAB and Federal Circuit ruled no nexus: evidence didn't tie tightly enough to the specific constricted convection claims amid larger display products.

Does the nexus trap affect AI hardware patents?

Absolutely—modular AI components like cooling or chips face same scrutiny; inventors may pivot to trade secrets or broader claims.
