Value Delivered
GreyB helped the client build a strong obviousness case against a medical device patent by uncovering critical prior art across both patent and non-patent literature. By bridging a key technical gap that conventional patent searches had failed to close, the client gained the invalidating evidence needed to challenge the patent with confidence.
Problem Solved
The client needed to invalidate a patent claiming a specific embolic protection device structure deployed in the ascending aorta. Standard patent searches returned results that were close, but not close enough. Each reference covered only part of the picture, leaving a critical gap that made the obviousness argument difficult to sustain.
With the prior art cutoff fast approaching, the team needed a smarter approach.
Solutions Offered
GreyB went beyond conventional patent databases, adopting a domain expert’s mindset to identify where the missing technical knowledge would realistically be documented.
When literature searches narrowed the gap but couldn’t close it entirely, the team took an unconventional step: directly consulting a subject-matter expert whose guidance pointed to a key non-patent reference that proved decisive.
This single insight bridged the gap between the available prior art and the target claim, enabling GreyB to map all three required features across multiple sources and deliver a conclusive obviousness argument.
