What company spun off Grail?

Can you enlighten me on the origins of Grail? Which company, with its expertise and resources, was responsible for the birth of this entity? I'm curious to know the lineage behind Grail and how it emerged from its parent company. It would be insightful to understand the motivation and vision that led to this spin-off, as well as the implications it may have had on both the original company and Grail itself.
