Patents and intellectual property rights protect deep investments in breakthrough therapeutics, diagnostics and medical devices. Challenges to patents and claims of anticompetitive practices expose companies to steep liabilities. Katten guides and defends medical pioneers where they converge with regulatory oversight and commercial disputes. Our attorneys have triumphed at trial and settled countless threats for some of the world's largest pharmaceutical and biotech companies.

Defending pharma investments and company growth

Competition places pressures on pharma’s patent budgets, development timelines and corporate behavior. We protect top-10 generic, biosimilar and specialty brands, as well as drug and device makers, against harmful allegations and threats to intellectual property. Experienced in matters involving more than 45 drugs and dozens of trials, we reduce the uncertainty of litigation by targeting the issues that matter most in:

  • Accounting investigations
  • Abbreviated Biologic License Applications
  • Abbreviated New Drug Applications
  • Antitrust
  • At-risk launches
  • Breach of contract and commercial claims
  • Fraud
  • Hatch-Waxman Act, Paragraph IV litigation
  • Monitorships
  • Patent infringement and invalidity

Managing disputes and government oversight

Regulations create distinct obligations for life sciences companies and their executives. Understanding the nuances of patent, Food and Drug Administration, and antitrust regulations has allowed our trial attorneys and litigators to effectuate the law and prevail in novel arguments. Katten navigates drugmakers through the post-FTC v. Actavis landscape, counseling to prevent litigation from arising in patent agreements and avoid claims of uncompetitive behavior. We maintain productive relationships with the:

  • Federal Trade Commission
  • US Department of Justice
  • US Food and Drug Administration
  • US Patent and Trademark Office

High-stakes trial advocacy nationwide

Katten attorneys are a familiar and effective presence in high-profile patent jurisdictions, including Illinois, New Jersey and Delaware, and in state and federal trial and appellate courts, the International Trade Commission, and the Patent Trial and Appeal Board. In addition to our work with established medical and pharma companies, we advise emerging enterprises on intellectual property, disclosure, fundraising and other regulatory responsibilities.

  • Represented global pharmaceutical company Apotex in US District Court for the District of New Jersey and Federal Circuit.

  • Represented biopharmaceutical company Amarin in a 10b-5 securities class action in the US District Court for the District of New Jersey. The client’s lipid-lowering drug had been approved by the FDA for use in a small market of patients with extremely high cholesterol levels. When the FDA declined Amarin's application to approve the drug for patients with moderately elevated levels, the stock price declined. Plaintiffs alleged Amarin misrepresented to investors the likelihood that it would obtain FDA approval for the broader indication by not revealing certain information to shareholders about a prior meeting with the FDA. The court dismissed the case as the allegations in the complaint were not specific enough to meet the bar for securities class actions, and some of the claims did not allege misconduct. Plaintiffs filed a second consolidated amended class complaint that was also dismissed; the US Court of Appeals for the Third Circuit affirmed the dismissal and denied a petition for rehearing en banc.
