(Dyk) Reversing stipulated judgment of non-infringement based on faulty claim construction. “While it is highly undesirable to consider these [claim construction] issues in the abstract, . . we have proceeded to do so.” “Colorant selection mechanism” was a means plus function element, while “aesthetic correction circuitry” was not. Michel dissented.
