Silver - Individuals: litigation
Arnold & Porter thrives in the cut and thrust of pharmaceutical and biotechnology patent litigation and is a go-to for representation in the most complex and highest-exposure cases. One look at its line-up in New York settles any nerves: David Barr, Daniel Reisner, Aaron Stiefel and Daniel DiNapoli bring a tremendous amount of experience to the table and have seen and done it all before. Coming in for praise, Barr is a “detail-oriented lawyer and deep thinker who is excellent on the technical aspects of his craft”. He recently linked up with DC’s Matthew Wolf to win a jury trial for Hologic and Grifols against bioMerieux regarding blood-screening assays. He and Reisner – as well as Wolf and Silicon Valley partner Deborah Fishman – also secured a major victory for Sanofi and Regeneron against Amgen, which had sought billions in damages and a permanent injunction against the sale of Sanofi and Regeneron’s cholesterol-reducing drug Praluent. Stiefel and DiNapoli, meanwhile, have continued their sterling representation of Pfizer against generic challenges to multiple blockbuster drugs, including Xeljanz, Viagra and Celebrex.
