Legal 500 Editorial commentary

Testimonials

Collated independently by Legal 500 research team.

  • ‘The Willkie team was a pleasure to have as co-counsel. The team was diligent, collaborative, and trustworthy.’

  • ‘We worked closely with Krista Schwartz and Barrington Dyer. Both were smart, strategic and great to have as co-counsel.’

  • ‘Patent litigation is a deeply technical practice that requires both legal acumen and the ability to understand complex technologies. All great patent litigators are great litigators, but not all great litigators are great patent litigators. They are agile, smart, creative, and communicative.’

  • ‘Indranil Mukerji, Stephen Marshall, Aliza Carrano and Barrington Dyer each played an integral role in a significant patent litigation matter for us. Each of them individually contributed, but I was most impressed at the team's cohesion and collective ability to tackle complex issues in real time.
