Introduction
The case of Cosmo Technologies Limited v. Actavis Laboratories FL Inc. is a significant patent infringement lawsuit that highlights several critical aspects of patent litigation, including claim construction, expert testimony, and the criteria for determining exceptional cases under 35 U.S.C. § 285. Here, we delve into the key points and analysis of this case.
Background
In February 2015, Cosmo Technologies Limited, Valeant Pharmaceuticals International, and Valeant Pharmaceuticals Luxembourg S.A.R.L. (collectively, "Plaintiffs") filed a lawsuit against Actavis Laboratories FL Inc. and Alvogen (collectively, "Defendants") for the infringement of six patents related to controlled-release pharmaceutical compositions containing budesonide, used to treat ulcerative colitis[1][3][4].
Patents in Dispute
The patents at issue included U.S. Patent Nos. 7,410,651, 8,293,273, 8,784,888, RE 43,799, and 9,320,716. The Plaintiffs alleged that the Defendants' products infringed over 50 claims across these patents[1][3].
Claim Construction and Litigation Process
During the litigation, the court ordered the Plaintiffs to narrow down the claims to a maximum of two claims per patent against each defendant. The Plaintiffs eventually dropped the '716 patent and asserted one claim from each of the remaining patents against the Defendants. The bench trial commenced on May 22, focusing on the '888 patent against both Defendants and the '273 patent against Actavis only[1].
Judgment as a Matter of Law
Following the close of the Plaintiffs' case-in-chief, the Defendants moved for judgment as a matter of law (JMOL) under Federal Rule of Civil Procedure 52(c) on non-infringement. The court granted this motion, finding that the Plaintiffs failed to provide sufficient evidence to support their infringement claims. Specifically, the court noted that the Plaintiffs never provided samples of the accused products to their primary infringement expert, Dr. Davis, to conduct a "naked eye" test as required by their own claim construction[1].
Failure to Conduct Necessary Tests
The court criticized the Plaintiffs for not conducting feasible tests to determine the presence of stearic acid in the accused products. Instead, the Plaintiffs' experts performed other tests that did not address the critical issue. This failure, combined with Actavis's repeated assertions that their product did not contain stearic acid, was deemed objectively unreasonable and highlighted the substantive weakness of the Plaintiffs' claims[1].
Reliance on Inadequate Evidence
The Plaintiffs' reliance on a 1991 article that tested a different grade of magnesium stearate was also found unconvincing. The court emphasized that this evidence did not support the Plaintiffs' infringement allegations[1].
Appeal and Affirmation
On January 14, 2019, the Court of Appeals for the Federal Circuit summarily affirmed the district court's entry of judgment for the Defendants, upholding the finding of non-infringement[1].
Exceptional Case Determination
The Defendants sought an order for the Plaintiffs to pay attorney fees under 35 U.S.C. § 285, arguing that the case was exceptional due to the Plaintiffs' objectively unreasonable litigation conduct. The court granted this motion in part, finding that the Plaintiffs' failure to conduct necessary tests and their reliance on weak evidence justified the award of attorney fees[1].
Claim Construction Disputes
The case also involved disputes over claim construction, particularly regarding the term "macroscopically homogenous composition." The court adopted the Plaintiffs' proposed construction, which required the composition to be uniform to the naked eye. However, the Defendants argued that this construction was flawed because it did not account for distinct, concentric layers that could be seen. The court ultimately upheld its previous construction, finding no basis to depart from the plain and ordinary meaning of the term[3][4].
Industry Implications
This case underscores the importance of thorough pre-litigation investigation and the necessity of conducting relevant tests to support infringement claims. It also highlights the risks of pursuing litigation with weak or unconvincing evidence, which can lead to adverse judgments and the imposition of attorney fees.
Best Practices for Patent Litigation
- Conduct Thorough Pre-Suit Investigations: Ensure that all necessary tests and analyses are performed to support infringement claims.
- Provide Clear and Relevant Evidence: Make sure that expert testimony is based on relevant and feasible tests.
- Narrow Claims Reasonably: Comply with court orders to narrow claims to focus on the most critical issues.
- Avoid Reliance on Weak Evidence: Ensure that any evidence presented is robust and directly relevant to the claims at issue.
Key Takeaways
- The case emphasizes the importance of conducting necessary tests and providing robust evidence to support patent infringement claims.
- Failure to do so can lead to adverse judgments and the imposition of attorney fees under 35 U.S.C. § 285.
- Claim construction is a critical aspect of patent litigation, and parties must ensure that their constructions align with the plain and ordinary meaning of the terms.
- The Federal Circuit's affirmation of the district court's judgment underscores the importance of thorough pre-litigation preparation.
