Introduction
The litigation between Pfizer Inc. and Teva Pharmaceuticals USA, Inc. is a significant case in the pharmaceutical industry, highlighting the complexities and stakes involved in patent infringement disputes. This article will delve into the key aspects of the case, including the background, legal proceedings, and the outcomes.
Background
Pfizer Inc., one of the world's largest pharmaceutical companies, developed Protonix® (pantoprazole), a blockbuster medication for treating acid reflux. The patent for pantoprazole, owned by Takeda and licensed exclusively to Wyeth (a Pfizer subsidiary) in the United States, was set to expire in January 2011[1].
The Dispute
Teva Pharmaceuticals USA, Inc. and Sun Pharmaceutical Industries, Ltd. launched generic versions of Protonix® before the patent expiry, a move known as an "at-risk" launch. This action prompted Pfizer and Takeda to initiate litigation, alleging patent infringement under United States Patent No. 4,758,579[1].
Legal Proceedings
The case was heard in the New Jersey federal court. Here are the key milestones:
Trial and Jury Verdict
A jury determined that Teva and Sun's "at-risk" launches of generic pantoprazole violated the patent. This ruling was crucial as it established the infringement, paving the way for the subsequent settlement[1].
Settlement
After nearly a decade of legal battles, Pfizer, Teva, and Sun reached a settlement. Under the terms, Teva and Sun agreed to pay a total of $2.15 billion to compensate Pfizer's subsidiary Wyeth and Takeda for the damages incurred due to the patent infringement. Teva would pay $1.6 billion, with $800 million paid in 2013 and the remaining $800 million by October 2014. Sun would pay $550 million in 2013[1].
Key Arguments and Defenses
Infringement Claims
Pfizer alleged that Teva's ANDA (Abbreviated New Drug Application) filing for generic pantoprazole was an act of patent infringement, as it sought approval to manufacture, use, or sell a drug claimed in the patent[4].
Validity and Obviousness
Teva challenged the validity of the patents, arguing they were obvious over prior art. However, the district court rejected these arguments, finding the patents valid and not obvious[4].
Best Mode and Double Patenting
Teva also raised defenses related to the best mode requirement and double patenting. The court rejected these defenses, holding that Pfizer's subjective preference for COX-2 selectivity did not violate the best mode requirement and that the patents in question did not constitute double patenting[4].
Outcomes and Implications
Financial Settlement
The $2.15 billion settlement was a significant outcome, reflecting the substantial damages incurred by Pfizer and Takeda due to the early launch of generic versions of Protonix®[1].
Admission of Infringement
Both Teva and Sun admitted that their sales of generic pantoprazole infringed the patent, which was a critical acknowledgment of their liability[1].
Industry Impact
This case underscores the importance of protecting intellectual property in the pharmaceutical industry. It highlights the lengths to which companies will go to defend their patents and the financial consequences of patent infringement.
