Cahill has been recognized in the 2026 IAM Patent 1000 guide. IAM commended the firm for its outstanding patent litigation practice, particularly in market-defining pharmaceutical, biotechnology, and Hatch-Waxman–related matters.

Additionally, four Cahill partners were honored: 

  1. Peter Armenio (Gold, New York)
  2. Chris Campbell (Bronze, D.C. Metro Area)
  3. Gerald Flattmann (Gold, National)
  4. Colleen Tracy James (Silver, New York)

These members of the Cahill team were recognized by IAM for their extensive and longstanding success in pharmaceutical and biotechnology matters, with IAM specifically highlighting the “intensity of [the team’s] focus” and their sophisticated ability to handle “patent issues that often sit at the intersection of exclusivity, regulation and commercial strategy.”

Each year, the IAM Patent 1000 guide compiles and endorses the nation’s top firms and attorneys in the field of patent law, and the guide is widely regarded as a go-to resource for those seeking outstanding legal counsel in intellectual property.
