For legal market watchers it has been exciting to see Arnold & Porter’s success in the courtroom over recent years; it has put in resonant performances for innovation leaders in disputes that really matter at a technical, legal and business level. Essential to this story are the contributions of New Yorkers Daniel DiNapoli, Aaron Stiefel and Dan Reisner, who have a vast amount of collective experience. DiNapoli and Stiefel, meanwhile, have been representing Pfizer in Hatch-Waxman litigations in defence of blockbuster products under its Xeljanz brand. The firm has a longstanding relationship with Pfizer and has produced sterling results relating to many of its products, including Viagra and Celebrex, in much of which Reisner has also been involved. Reisner is a dynamic trial lawyer with skills, knowledge and experience cutting across life sciences and tech.
