Invalidity Search to Avoid $3M in Royalties on a Glucosinolate Removal Process

Featured Image of How GreyB Helped Client Avoid $3M in Royalties by Invalidating a Patent Claim on Glucosinolate Removal Process

Value Delivered

GreyB identified crucial prior art that invalidated a patent claim on the use of heat and pressure to remove aliphatic glucosinolates from Brassica plants. The research protected the client’s product and helped them avoid potential royalties and licensing costs exceeding $3 million.

Problem Solved 

The client sought prior art to invalidate a patent claim involving the use of heat and pressure to remove aliphatic glucosinolates from Brassica plants. A preliminary search found no relevant prior art despite examining decades of research on glucosinolates dating back to 1951. The main challenge was finding specific combination of heat and pressure mentioned in the patent claim.

Solutions Offered

The team’s creative search strategy involved reviewing decades of literature, books, and expert interviews. The breakthrough came when they identified a newspaper article from a researcher working on removing anti-nutritional compounds from Brassica.

GreyB then contacted the researcher, uncovering a crucial insight. This led the team to focus on specific Brassica varieties and refine their search on high-pressure, high-temperature processing in these plants. Ultimately, they discovered prior art that confirmed the method to reduce aliphatic glucosinolates—exactly what the patent claimed—helping to invalidate it.
