AMS Trade LLP > The Legal 500 RankingsAMS Trade LLP in January 2022, following the departure of founding partner Tom Schaumberg. The firm is renowned for its outstanding track record and exceptional ‘in-depth expertise’ in ITC investigations, hailed by some as ‘go–to-law firm for Section 337 investigations’. The sizable Washington DC-based practice comprises some of the market’s most experienced names, including founding partner Louis Mastriani and managing partner Deanna Tanner Okun, who served two terms as chairman of the International Trade Commission. Regularly acting for plaintiffs and defendants and operating both as stand-alone counsel or in collaboration with other firms, the group represents clients from a wide variety of sectors, mainly technology, life sciences and consumer products. The practice is further strengthened by a ‘highly competent’ second line of experts composed of partners Lauren Peterson and Daniel Smith. Paul Bartkowski left in January 2021.
‘Compared with other law firms working on 337 cases, the firm is the most experienced and efficient one.’
‘Since 337 investigations often involve complex technology, lawyers need to work with experts and law firms with different background. AMS lawyers are very cooperative with various teams that we worked together. More importantly, AMS charges reasonably.’
‘They are the go-to-law firm for Section 337 investigations, having been directly involved in almost one-third of all Section 337 cases filed before the International Trade Commission.’
‘I have worked directly with Deanna Okun, Daniel Smith, and Lauren Peterson and found each of them to be highly competent and great to work with.’
‘Great team with in-depth expertise on ITC litigation.’
