Strategies for Preparing Infringement and Validity Opinions

A company must be strategic in any business decision it makes in order to ensure that it takes the necessary measures to avoid liability for its actions. With respect to patent infringement, and specifically willful patent infringement, the different approaches to determining which measures to take and when to take such measures have been repeatedly challenged in light of a number of court decisions in recent years. To set the scene, the Federal Circuit held in Underwater Devices Inc. v. Morrison-Knudsen Co., 717 F.2d 1380 (1983) that a potential infringer has an affirmative duty to exercise due care to determine whether or not he or she is infringing. This placed the burden on the potential infringer to seek competent counsel and obtain either a non-infringement opinion or invalidity opinion prior to undertaking the possible infringing activities. This would prevent a finding of willful infringement and treble damages.

Willful Infringement, Opinion Letters, & Post-Halo Trends

In one of the first district court cases to apply Halo, the Eastern District of Pennsylvania was confronted with a defendant who obtained a noninfringement opinion sometime around the final day of a 12 to 18 month project. See: Dominion Res. Inc. v. Alstom Grid Inc., No. CV 15-224, 2016 WL 5674713 (E.D. Pa. Oct. 3, 2016) (holding that the defendant’s state of mind on the final day of 12-18 month project was far too late to be defense to willfulness) (appeal pending). The court ruled that opinion letters obtained so long after infringement began, even if still during the period of infringement, did not absolve the defendant of willful infringement under a subjective recklessness standard. Shortly thereafter, the District of Delaware was confronted with a case in which the defendant obtained a noninfringement and invalidity opinion well before litigation, and the defendant even modified designs of the products at issue to conform to recommendations contained therein…
