In determining indefiniteness of a claim based on a testing method referenced in the patent, courts will evaluate whether the method is well known in the art and could reasonably be adapted for the claimed purpose. Intervening rights is an affirmative defense that may arise when claims are substantially changed after an intervening reexamination. For lost profits, a non-infringing alternative does not have to be a direct substitute; it can be an alternative in a hypothetical market absent the infringing product. Enhanced damages are discretionary and may be declined when willful infringement is not egregious, e.g. in light of its defenses and when patentee amended its claims in reexamination. Irreparable injury based on an erroneous lost profits finding will not stand. Further, a permanent injunction may be reconsidered by evaluating the sales in the actual market after the grant of an injunction.
