Federal Circuit -- THE FOX GROUP, INC. V. CREE, INC.

Patent claimant does not need to prove conception where reduction to practice is established and antedates the other claimant.

Reduction to practice is different from repeatability.

No case or controversy with reference to unasserted claims.

THE FOX GROUP, INC. V. CREE, INC.
