Narrative Opinion Summary
This case concerns an appeal by Teva Pharmaceuticals USA, Inc. from a judgment by the United States District Court for the District of New Jersey, which favored Pfizer, Inc. in a patent infringement suit. Pfizer claimed that Teva's Abbreviated New Drug Application (ANDA) for a generic version of Celebrex infringed upon its patents. The district court found Teva infringed on three Pfizer patents and rejected Teva's defenses of invalidity based on best mode and inequitable conduct. However, on appeal, the court invalidated claims of the ’068 patent due to obviousness-type double patenting in relation to the ’165 patent, while upholding the validity of claims in the ’823 and ’165 patents. The court ruled that the safe harbor provision of 35 U.S.C. § 121 did not apply to the ’068 patent, as it was a continuation-in-part rather than a divisional application. The decision partly affirmed and partly reversed the district court's judgment, maintaining some patent claims' validity while invalidating others, resulting in a mixed outcome for the parties involved.

Inequitable Conductsubscribe to see similar legal issues
Application: The court ruled that Teva failed to establish inequitable conduct by Pfizer, as there was no intent to deceive the PTO.
Reasoning: Teva argued that Pfizer failed to disclose two Merck publications during the patent prosecution process. However, the district court found that neither the ’501 application nor the ’995 patent was material to the patents in question.
