    Winston & Strawn LLP

    Winston & Strawn LLP remains one of the most sought after trial firms in the country and is especially active in defense litigation. The group's recent successes in 2019 confirmed its reputation as one of the finest dispute addresses in the US, with several high-profile Federal Circuit wins and successes in district courts across the country adding to the team's track record. With its historic bases in Chicago, New York and Washington DC and its more recent hubs in California and Texas, the practice has a foot on the ground near all major litigation venues in the US, ready to try cases from a wide range of sectors, including the life sciences, pharmaceutical and technology sectors. Section 101 invalidity motions are an instrument that the practice wields especially well. David Enzminger in Los Angeles, Charles Klein in Washington DC and New York's Thomas Patrick Lane form the trio at the helm of the practice which includes Chicago's Kurt Mathas. The firm saw multiple departures in 2019: Thomas Dunham joined Ruyak Cherian LLP, Vivian Kuo and Andrew Sommer joined Greenberg Traurig LLP, Paul McGrady joined Taft, Stettinius & Hollister LLP, Scott Samay left for Lerner David Littenberg Krumholz & Mentlik, LLP, Eric Schlichter joined McGuireWoods LLP, Jonathan Retsky left for Bryan Cave Leighton Paisner LLP and Kathleen Barry became senior litigation counsel at Corning. Allan Fanucci retired.


    Winston has a very experienced team in many different types of IP litigation, including pharmaceuticals. The team has first chair lawyers who have a deep understanding of the science and can provide unique perspectives to clients. Judges and opponents immediately respect the firm and they draft well-reasoned briefs and motions. The team appreciates how the industry functions, business considerations, and work with clients to respond to market dynamics.

    Fantastic lawyers with a very deep bench of scientific knowledge and degrees.  I find them to be always professional and always enjoyable to work with.

    Having worked with a number of firms on litigation around the world, I was surprised by how much of a step-up Winston Strawn are. They are technically superior, commercially astute and easy to work with.  Always prepared and a step ahead in terms of their thinking, I never have to chase them for work product or worry that they have missed something.

    Ivan Poullaos is client-oriented, very intelligent and has tremendous experience in pharmaceuticals. Ivan strives to work closely with clients and make sure their priorities are addressed. Ivan is a great case manager ensuring the right arguments are advanced at trial rather than every argument (good or bad).

    Kurt Mathas is the real deal, he knows the law backwards and forwards, gives fantastic strategic advice, is able to wrap his head around deep scientific theories despite no formal academic training and is simply a pleasure to work with. He and his team go above and beyond at every turn.

    Kurt Mathas is an outstanding litigator. He has an exceptional ability to grasp the underlying science and a mastery of our case. I am continually amazed at how he handles our case almost single-handedly – while he calls on the right support when needed, we do not suffer from a bloated team or a feeling that he needs to have other lawyers with him for support.

    The Paul Weiss team understands that what counts as a ‘win’ in a certain case really depends on our business objectives.  They, unlike many firms I’ve worked with, are not surprised and often anticipate that certain approaches to aspects of litigation may not be options for us, given our business objectives.  In addition, their ability to dive into complex scientific issues and meet the witnesses where they are is equally impressive. While they understand the technology, they never lose sight of the fact that ultimate the trier of fact also needs to understand these issues.

    They know the practices and litigation strategy well and are very smart.

    Catherine Nyarady: She is good at communicating with the clients and the courts.

    Knobbe Martens Olson & Bear LLP

    Knobbe Martens Olson & Bear LLP, one of the largest and most established IP boutiques in the US, impresses with a particularly high number of practitioners with a science or engineering degree and its extensive trial expertise, both in the district courts and at the Federal Circuit. The group acts for plaintiffs and defendants alike, with a track record of successes above the national average, not only in federal court, but also before the PTAB where the prolific practice is especially successful for patent owners. The group's East coast and West coast teams regulary join forces for optimal representation in court, a key selling point for its diverse client roster that includes major life sciences, pharmaceutical, technology, consumer products and electronics players, many of which have stayed with the firm for decades.

My company works with a decent number of law firms, and I have to say the Knobbe Martens relationship is at the top of my list for the level of quality, value, commitment, and overall client satisfaction.  I know that I am getting value when working with this team and it is money well spent.  It is hard to find firms and teams that are deeply invested, committed, that act as strategic value-added partners and not just a service provider.  Knobbe Martens is definitely the deeply invested, committed, strategic value-added partner. I feel like I have the A-Team on my side.

    The Knobbe Martens team has always approached each case with thoughtfulness. The Knobbe Martens team does a great job of using current trends in IP litigation to guide their strategy and helps us to craft a precise approach rather than a generic one-size-fits-all strategy that I have seen in many firm’s proposals.

    A pragmatic firm that routinely finds the experience/knowledge required for a given challenge and makes it available to us.

    The group of attorneys working in our patent litigation team are some of the best I’ve seen. They are all committed, dedicated, engaged, and work to maximize value for us.

    Joseph Re- his presence in the courtroom is unparalleled. He commands a presence, has an exceptional grasp of the law and our case.  He is passionate about our case and it comes through in his persuasive arguments.’

    John Sganga has truly earned my trust over the years as a conscientious litigator who always keeps the company’s best interest in focus throughout proceedings. He is reserved and thoughtful during the planning process, but confident and assertive in his communications with opposing counsel, etc.

The mix of legal, engineering and science expertise offered by the team makes the practice an attractive choice for a growing number of high-profile companies, not the least because the firm also impresses with its prosecution and licensing capabilities. The combination has proven to be particularly appealing for clients from highly regulated sectors, chief among them life sciences companies, but the team's caseload reveals a diverse sector mix which also includes electronics, technology and consumer products clients.

Lisa Blatt joined from Arnold & Porter and heads the firm's appellate and Supreme Court practice. Sarah Harris joined from the US Department of Justice, further bolstering the group's appellate and Supreme Court practice.


    The team I worked with at Williams & Connolly brought a focused and detail-oriented approach to our representation. I felt that their advocacy was consistently much better than that of our adversary – which (obviously) put us at a big advantage. Williams & Connolly thinks around the corners, and is aggressive in an intelligent, strategic way. I appreciate that the partners are supportive of development opportunities for their associates. Their written work product is top-notch. They were also great partners and really took the time to listen to and absorb feedback. I truly enjoy working with them.

    Thomas Selby is a great lead partner. He is warm and inclusive, and maintains good relationships with everyone (court reporters, opposing counsel, his associates, and his clients).  He’s very sharp and excellent in depositions and other situations that require quick thinking.

    Adam Harber is incredibly hard-working, super sharp, and can absorb and hold very tricky, nuanced, technical information without getting lost in the weeds – rather, he keeps the litigation strategy mindset top of mind at all times, and uses the technical information to serve that strategy. He’s also an excellent oral advocate – clearly articulating the important points, nimbly and succinctly responding to arguments from the bench and opposing counsel.

    David Krinsky can speak English as well as Engineering and helped to translate the technical details into persuasive arguments.  Like the rest of the team, David is also a delightful person who I enjoyed spending time with on a personal level.  He is also a great (and funny) writer.
