Introduction
The litigation between UCB, Inc. and Mylan Technologies Inc. is a complex and multifaceted case that revolves around patent infringement claims related to the drug Neupro®, a transdermal patch used to treat Parkinson’s disease and restless leg syndrome. Here, we will delve into the key aspects of this case, including the background, the patents in suit, the legal proceedings, and the outcomes.
Background
UCB, Inc., a global biopharmaceutical company, developed Neupro®, which is protected by several patents. Mylan Technologies Inc., a generic and specialty pharmaceutical company, sought to market a generic version of Neupro® through an Abbreviated New Drug Application (ANDA) with the FDA.
The Patents in Suit
The litigation involves multiple patents, including U.S. Patents Nos. 8,246,979 and 8,246,980, as well as U.S. Patents Nos. 10,130,589 B2 and 10,350,174 B2[1][5].
Initial Litigation and Settlement Attempts
In 2017, UCB filed a complaint in the District of Delaware alleging that Mylan’s ANDA infringed five of UCB’s patents. The case was later transferred to the District of Vermont. The parties attempted to negotiate a resolution, resulting in a stipulation of dismissal on May 13, 2020, with UCB agreeing to a covenant not to sue on the drug products described in Mylan’s ANDA at that time. However, this covenant did not include any future amendments or supplements to the ANDA[1].
Major Amendment and New Litigation
On October 27, 2022, Mylan submitted a major amendment to its ANDA and notified UCB with a paragraph IV certification, arguing that the changes did not alter the infringement analysis and thus the covenant not to sue still applied. UCB responded by filing a new lawsuit and obtaining a 30-month stay of approval for Mylan’s ANDA[1].
Court Rulings and Arguments
Mylan moved for partial summary judgment, arguing that UCB breached the covenant not to sue and seeking a declaration that it did not infringe the ’979 and ’980 patents. The court disagreed with Mylan’s interpretation that the covenant covered modifications and supplements to the product. Instead, it found that the covenant applied only to Mylan’s ANDA product as described at the date of the settlement. The court also determined that UCB had the burden of proving that Mylan’s changes to the ANDA altered the infringement analysis, leading to a denial of Mylan’s motion for summary judgment[1].
Parallel Litigation and Precedent
Parallel litigation in the District of Delaware involved similar patent infringement claims against another company, Actavis Laboratories UT, Inc. In this case, the court ruled that the preamble of claim 1 of the ’589 patent was nonlimiting, a decision that was adopted by the Vermont court in the UCB v. Mylan case[5].
Key Decisions and Outcomes
- Delaware Decision: The Delaware court held that the preamble of claim 1 of the ’589 patent was nonlimiting, which was later adopted by the Vermont court[5].
- Vermont Court Rulings: The Vermont court found that the covenant not to sue applied only to the original ANDA product and not to any amendments or supplements. It also denied Mylan’s motion for summary judgment due to the existence of a fact issue regarding whether Mylan’s changes altered the infringement analysis[1].
- Mylan’s Victory in Earlier Phase: In an earlier phase of the litigation, Mylan won a significant victory when Judge Christina Reiss in Vermont ruled in Mylan’s favor, invalidating one of UCB’s patents and avoiding a bench trial[3].
Market and Legal Implications
This litigation highlights the complexities and challenges in pharmaceutical patent disputes, particularly when generic manufacturers seek to enter the market.
