NJ District Courts Bar Defendants’ Indefiniteness Argument During Claim Construction Because Not Alleged in Invalidity Contentions
We previously reported that New Jersey District Court Judges will limit a patent infringement defendant’s discovery to the claims and defenses identified in its Invalidity Contentions served under Local Patent Rule 3.3. For the same reasons, a defendant may be barred from taking certain positions during claim construction. In an opinion issued last week, Judge Jose L. Linares held in Auxilium Pharmaceuticals, Inc. & FCB I LLC v. Watson Laboratories, Inc., No. 12-3084 (JLL) that a defendant that does “not raise an indefiniteness defense in its invalidity contentions . . . cannot seek a determination that the patents-at-issue are invalid for indefiniteness through claim construction.”
