Federal Circuit -- BETTCHER INDUSTRIES, INC. V. BUNZL USA, INC.

Complex patent case - jury might reasonably have found infringement where competitor's products 'wear down' to a similar shape and function. 

Deft had adequate time to press claim construction at trial, no error in jury instructions.

(Again, these quick summaries are hardly comprehensive and quite possibly incorrect.)

Dissent - Patent void for anticipation.
