Nestle has around 276,000 employees today, while Dualit seems to have around 100-200 (hard to tell since Dualit is private).

And for one case of a small entity successfully defending against a Behemoth there's hundreds of cases where it was the exact opposite.

You are asking the wrong question IMO.

We really want examples of large companies licensing patents or buying smaller companies for their patents. Both are examples of patents helping smaller companies against those much larger. If patents no longer existed those smaller companies would get nothing.

This is the business model of patent trolls.
