Other key lawyers:

Thomas Goldstein; Sarah Harrington


Goodwin’s ‘exceptionally strong’ appellate work encompasses ERISA and regulatory litigation; high-profile client representations in sectors such as financial services, pharmaceuticals, and life sciences; and cases at their certiorari and merits stage brought before the US Supreme Court. In a recent standout appearance before the US Supreme Court, a team led by Brian Burgess assumed pro bono representation for Texas prisoner Gregory Banister and persuaded the Justices to reiterate the distinction between a prisoner’s first and second petition for a writ of habeas corpus; the victory comes with significant implications for the appellate rights of convicts. Moreover, the group does not cease to chart high-profile wins in IP appeals at the Federal Circuit. In this regard, clients single out practice co-head William Jay for being able to ‘address difficult questions from the judges that were not part of the briefing’. Multiple highly regarded appellate specialists are also based in Boston, where Kevin Martin leads a group including David Zimmer and associate Gerard Cedrone.

Practice head(s):

William Jay; Kevin Martin

Other key lawyers:

Brian Burgess; David Zimmer; Jaime Santos; Andrew Kim; Gerard Cedrone


‘Top-notch appellate practice in an efficient and effective team.’

‘Having seen William Jay argue a case on our behalf in front of the Court of Appeal for the Federal Circuit, I was very impressed. Willy was quick on his feet and was able to address difficult questions from the judges that were not part of the briefing, while the opposing counsel fell on his face.

‘David Zimmer is a rising star with much potential.’

‘The firm’s Supreme Court and appellate practice is exceptionally strong. The firm has a great leader in Willy Jay, and real bench strength. The firm has a particularly strong and well-deserved reputation in the IP space.’

‘The firm has broad knowledge and experience enabling it to position cases well for appellate review, and to take complex legal propositions and make them simple and persuasive.’

‘Mike Giannotto is a smart, down-to-earth litigator who grasps the big picture and is adept at achieving very good practical results.’

‘Brian Burgess is a very good thinker and writer with the unique skill of taking complicated controversial topics and making them simple, understandable and logical.’

‘Jaime Santos is an astute and highly engaged lawyer who delved deeply but also efficiently into the legal issues on a high-profile appeal before the Second Circuit. She and her colleague provided the Board with a crystal clear, not overly-technical for non-lawyers, but also very sophisticated analysis of the case and proposed strategy. She then executed the same perfectly. Andrew Kim was the second member of the team and took the initial laboring oar of drafting the brief, which was then fully edited by Jaime such that I can’t say whose writing the final version represented; this is actually a positive outcome since the legal research was comprehensive, the analysis highly original and distinctive in harmonizing and proposing guidance in a messed-up area of the law, and the writing style was vigorous and persuasive. Stellar work.’

Former Principal Deputy Solicitor General Neal Katyal shares leadership of the department with the highly regarded Cate Stetson, who recently hit a milestone of 100 arguments at appellate stage. Katyal is a minority appellate star, whose US Supreme Court legacy will include breaking Thurgood Marshall’s record for a number of arguments presented by a minority litigator. The past year saw Katyal take the lead on acting on behalf of the respondents in the closely watched case of Fulton v City of Philadelphia, which raises significant issues relating to religious rights and certification of same-sex couples as foster parents.

Jenner & Block LLP

Jenner & Block LLP is a regular fixture in high-profile appellate proceedings in the US Supreme Court. Particularly, it stands out for its unsurpassed strength in federal constitutional law appeals and statutory claims. Group co-chair Jessica Ring Amunson is a preferred advisor for election law disputes; her much-in-demand expertise brought her before the US Supreme Court in some of the most high-profile pending cases, such as Brnovich v Democratic National Committee, a voting rights case in which she is representing Arizona Secretary of State Katie Hobbs. In another highlight, SCOTUS sided with a team led by practice co-chair Ian Heath Gershengorn and Lindsay Harrison in Financial Oversight and Management Board for Puerto Rico v Aurelius Investment, LLC, et al., in which the firm represented The Official Committee of Retired Employees in the Court’s quest to determine the constitutionality of the Board. Adam Unikowsky remains a key attorney for Supreme Court work, having recently acted in patent law matters. Further, the group has outstanding experience in the federal courts of appeal as well. Department co-chair Matthew Hellman successfully presented arguments on behalf of former Chipotle worker Carmen Alvarez and her attorneys in Chipotle Mexican Grill, Inc. v Alvarez, where the Fifth Circuit confirmed that a lower court did not enjoy personal jurisdiction over the clients and could not hold them in contempt for filing a lawsuit citing the US Department of Labor’s overtime rule. Notably, the Chicago-based group also brings significant appellate firepower due to the expertise of practice co-chair Michael Brody, whose recent work stands out at the Seventh Circuit, where he handled an IP appeal for Epic Systems Corp.

Jones Day

Jones Day’s team stands out for its well-rounded appellate experience, spanning everything from brief drafting to presenting arguments in some of the most widely reported cases in federal courts of appeal and supreme courts nationwide. The group’s unsurpassed excellence in politically loaded cases manifested itself in a recent win at the US Supreme Court, where Yaakov Roth scored a judgment overturning the conviction of Bridget Anne Kelly, former aide to the Governor of New Jersey, in Kelly v United States; the case was brought in the aftermath of the high-profile “Bridgegate” scandal involving federal property fraud. The team is also known for its work on appeals seeking to challenge state and federal regulations on constitutional and statutory grounds; appellate veteran Michael Carvin acted as lead counsel and argued for the petitioners in the currently pending Brnovich v Democratic National Committee case involving a challenge to Arizona’s voting provisions. Of counsel Beth Heifetz heads up the department, where of counsel Glen Nager and recently promoted partner Jeffrey Johnson are also key figures. In November 2020, Shay Dvoretzky departed to lead the appellate department at Skadden, Arps, Slate, Meagher & Flom LLP. Following his service as the 47th US Solicitor General, Noel Francisco returned to the firm in July 2020; he now serves as the partner-in-charge of the office in Washington DC.

Kirkland & Ellis LLP

In the words of a satisfied client, Kirkland & Ellis LLP houses ‘a great bench of lawyers’ who are ‘experts at brief writing as well as at appellate argument and everything in between’; this praise was echoed in conversations with all peers. Certainly, the team provides a full range of appellate law services, including strategic counseling and constitutional litigation, but it is particularly renowned for its work in the US Supreme Court. In this space, the ‘deep experience’ of former Solicitor General Paul Clement certainly stands out, with his track record of arguments in over 100 high-profile Supreme Court cases. Of recent note, Clement led a team including the well-known Erin Murphy on defeating the government and scoring a decisive 8-1 victory, convincing the US Supreme Court to reverse a lower federal court’s ruling and side with the petitioner in Moda Health Plan, Inc. v United States, a case raising questions regarding the interpretation of the Affordable Care Act. The department is equally efficient in the lower state and federal courts; it prides itself on having scored over 70 wins all over the country. Clients single out John O’Quinn (‘excellent at argument’) and William Burgess (‘a phenomenal brief writer’), a highly successful duo known for their IP litigation work at the Federal Circuit. George Hicks achieved a victory at the Fifth Circuit, where he argued for Westmoreland Coal Company in a case concerning healthcare obligations under the federal Coal Act. Apart from its distinguished presence in Washington DC, the firm also has notable appellate firepower in New York, where Jay Lefkowitz specializes in areas including corporate and product liability litigation.

Other key lawyers:

Paul Clement; Erin Murphy; George Hicks; John O’Quinn; William Burgess; Jay Lefkowitz


‘The appellate team at K&E has a great bench of lawyers that have a wealth of knowledge and experience at all levels of the federal courts.  They have lawyers that are experts at brief writing as well as at appellate argument and everything in between.  They have intimate knowledge of the workings of the courts and the preferences and personalities of the judges.’

‘The Kirkland & Ellis appellate team has truly great expertise in US Supreme Court practice (such as through Paul Clement and Erin Murphy). They are incredible brief writers and bring value to the team throughout the matter, even before it is on appeal.’ 

‘In this practice, the people are the key. They are exceptionally talented. They also work collaboratively with the client.’

‘John O’Quinn and William Burgess were an excellent team. William is a phenomenal brief writer and John is excellent at argument.’

‘Paul Clement’s deep experience with the US Supreme Court (in terms of arguing more cases than others) brings a real competitive advantage.’ 

‘Erin Murphy has developed her expertise through her US Supreme Court clerkship and oral argument experience before the Court.’

‘They hire and train really excellent lawyers and I highly value their expertise.’

Latham & Watkins LLP

Clients instruct Latham & Watkins LLP’s team due to its ‘exceptional appellate expertise and service’. It handles a full scope of appellate issues at any procedural stage, including successful arguments, brief writing, and multiple successful filings and oppositions to certiorari petitions. The practice is noted for its litigation strategy analysis work at the pre-appeal phase. It handles high-stakes mandates in the trial courts and in regulatory agency proceedings and in doing so, it routinely collaborates with the firm’s trial teams in substantive areas of the law, most recently in relation to securities and tort law claims. Global appellate group lead Gregory Garre is a market-leading practitioner and former 44th Solicitor General; he is known for his standout track record in the US Supreme Court, where he has presented arguments in 45 cases. Reflective of Garre’s excellent advocacy skills, the team has become a part of an interesting trend over the past years; an increase in 5-4 voting and swing voting in the US Supreme Court. The group’s SCOTUS work can also be trend-reversing; Roman Martinez took the lead on striking a win for the plaintiff in Babb v Wilkie, achieving a 8-1 judgment with significant implications for age discrimination claims standing in contrast to the Court’s consistently stringent approach to the "but for" causation test in cases involving federal employment legislation. Having formerly served as Assistant to the Solicitor General, Martinez (‘a nationally recognized appellate attorney of exceptional talent’) re-joined the group in 2017 and has been growing his US Supreme Court practice ever since. The firm also houses another highly regarded former Assistant to the Solicitor General in Melissa Arbus Sherry, who is recommended for her ‘terrific oral advocate style and the ability to take quick, sound, sophisticated decisions’. Further, the team’s high-profile appearances before lower courts of appeal are equally impressive; Richard Bress successfully led the appellate efforts for Merck, Eli Lilly, and Amgen in a DC Circuit case noted for its significance in the area of drug pricing.

Gregory Garre

Other key lawyers:

Melissa Arbus Sherry; Roman Martinez; Richard Bress; Michael Bern


‘We are a civil rights organization and retained Latham & Watkins LLP to work with us and co-counsel on two highly significant cases pertaining to the US Census. As one of the oldest civil rights legal organizations in the country, we typically rely on pro bono counsel to work with us in such cases. We have never seen work of a higher quality, done under such extreme time pressures, at all levels of court as was done by Latham in the census cases. They provided two large teams (not fully overlapping, except at the highest partner level) to each case. The most senior partners were fully engaged throughout the cases, which saw arguments before a three-judge district court panel and the Ninth Circuit twice. We typically wind up doing a lot of editing on important briefs done by pro bono counsel. Not so with Latham.’

‘Melissa Sherry was the primary oral advocate in one of the cases at both the trial and appellate level and Rick Bress at the other at the appellate level. Melissa showed a mastery of a complex and extremely large factual record, combined with a terrific oral advocate style and the ability to take quick, sound, sophisticated decisions on the spot in response to questions from the Court. Rick is a superb draftsperson with an excellent advocacy style that is at once authoritative and down-to-earth, a truly wonderful oral advocate.’

‘Latham and Watkins has provided pro bono representation to our organization on several matters related to veterans’ law. Latham has provided exceptional appellate expertise and service, and recently won a very important case for us at the Federal Circuit. I can state without reservation that they are the best firm with which we have partnered.’

‘Roman Martinez is the lead partner working with us, and he is a nationally recognized appellate attorney of exceptional talent. We value his and his teams’ collaboration with us, attention to detail, and excellent communication. We have three active matters the firm is assisting us with on a pro bono basis, and they have been extremely generous with their time and talent. Other individuals in the firm who have provided excellent value service include Michael Bern, Blake Stafford, Shannon Grammel, Barrett Tenbarge, and Genevieve Hoffman.’

‘Excellent advocacy skills. Extremely responsive. Great thinkers.’

‘It is truly a pleasure to follow Greg Garre’s appellate work, he is highly experienced to a level only a very few litigators can achieve.’

‘Roman Martinez is an excellent lawyer. He is a great strategic thinker. He is not afraid to push back on client direction, but does so very thoughtfully and professionally.’

Mayer Brown

The appellate lawyers at Mayer Brown are viewed by clients as ‘the best of the best’; they also ‘listen to clients and take their needs seriously’, while also ‘making the effort to develop a holistic view of the business of the client’. The team has extensive experience in the US Supreme Court, all federal courts of appeal, and numerous courts of appeal at state level. The group includes over 40 appellate specialists and is primarily split between New York and Washington DC, but also has appellate presence in Chicago where Michael Scodro is recommended. Data privacy specialist Lauren Goldman (New York) shares leadership of the group with the Washington DC-based star duo Andrew Pincus and Nicole Saharsky. Pincus is among the best appellate litigators in the country, having recently persuaded the US Supreme Court to grant a review to Cargill in a case involving interpretation of the Alien Tort Statute. A former Assistant to the Solicitor General, Saharsky has 30 US Supreme Court arguments under her belt; she is currently advising players of the US Women’s soccer team on their options to appeal an unfavorable equal pay judgment issued by a district court.

‘It is sometimes said that appellate practitioners are lawyers’ lawyers—the people to whom other lawyers turn for expert help. If that’s true, then the people in Mayer Brown’s Supreme Court and appellate practice are the lawyers’ lawyers’ lawyers—the best of the best. They are the people to whom other Supreme Court and appellate lawyers turn for expert help. What is more, the firm culture is about collaboration and client service. These folks care about the quality of the work, full stop. And they listen to clients and take their needs seriously. If you’re lucky enough to have the Mayer Brown’s appellate practice help you, you know that you’re getting the best legal work there is, from people who are also a pleasure to work with.’

‘Lawyers that are renowned expert appellate practitioners; deep experience; the firm has been counsel on numerous precedent-setting cases.’

‘The appellate team (particularly Mike Scodro and Britt Miller) have made a point of understanding the dynamics of our underlying business and the relationship of those dynamics to the appellate arguments made. It’s expected that a high-performing appellate team will have mastery of the record, but that record doesn’t fully reflect what drives the business. Making the effort to develop a holistic view of the business of the client sets this team apart.’

‘My personal favorites at Mayer Brown are Charles Rothfeld and Evan Tager. Charles not only has a piercing intellect but also understands the Supreme Court, the Justices, and what interests them as well as or better than anyone, anywhere. And Evan is perhaps the best writer of appellate briefs in the country. Samuel Taylor Coleridge said that poetry is the best words in their best order; Evan’s briefs are poetry. Plus, it’s been said that Evan has a jeweler’s eye for legal issues, and that is correct: he sees things that no one else does, and communicates them to courts as no one else can. And both Evan and Charles are absolute pleasures to work with, because, true to the culture of Mayer Brown’s appellate practice, there’s no ego to them. What drives them is the commitment to produce the best work absolutely all the time. And they do.’

‘Andy Pincus, Dan Himmelfarb, and Tim Bishop are all world-class Supreme Court lawyers. Miriam Nemetz and Brian Netter are fantastic as well.’

‘Associate Carmen Longoria-Green is extraordinarily smart, thoughtful, and strategic; and her briefs are truly spectacular.’

‘Lawyers that are renowned expert appellate practitioners; deep experience; the firm has been counsel on numerous precedent-setting cases. Trustworthy and pragmatic. Superlative work quality. Andrew Pincus and John Nadolenco stand out in this regard.’

‘Britt Miller is exceedingly capable across the board, but she has impressed me in two ways that stand out: she has an exceptional ability to coordinate a large team working on complex tasks in tight timelines, and she has a head for business strategy and understands how the legal issues and legal strategy intersect with where we want to take the business.’

‘Mike Scodro has struck me with his mastery of appellate strategy and the ability to select the right arguments to focus on and then articulate them concisely and persuasively.’

McDermott Will & Emery LLP

In the two years since its launch in 2019, McDermott Will & Emery LLP has been growing its presence in multiple federal courts of appeal. In a recent high-profile victory at the Eight Circuit, the team represented the Pharmaceutical Care Management Association in an ERISA case which is currently being considered by the US Supreme Court. The practice has a strong record at the SCOTUS as well; it scored a recent victory on behalf of the petitioner in Nasrallah v Barr, a case centering around interpretation of the interaction between the Immigration and Nationality Act, and the International Convention Against Torture. Department co-heads Paul Hughes and Michael Kimberly are both highly recommended by peers and clients alike, which praise them for their ‘unique team dynamic that plays off each of their strengths’.

Practice head(s):

Paul Hughes; Michael Kimberly

Other key lawyers:

Andrew Lyons-Berg


‘McDermott Will & Emery has been an excellent law firm for many years, but the addition of Paul Hughes and Michael Kimberly vaulted them into the top echelons of appellate practice practically overnight. In-house counsel should be able to take for granted that most top appellate practices are run by brilliant lawyers. That is simply table stakes. But Paul and Michael have unique qualities that set them apart even in this hyper-competitive space.’

‘Paul Hughes – it is not a stretch to picture Paul as a future Solicitor General. He possesses legal skills in spades, but also demonstrates a surprisingly high policy awareness that sets him apart in Washington.’

‘Michael Kimberly. When hiring a firm to engage in a set of APA cases, I joined a small panel of senior in-house counsel to interview a dozen or so top-notch specialty practices in that particular area of law. Although Michael has plenty of experience in APA cases, you wouldn’t necessarily expect someone with a more general appellate practice to be as deep on the niche issues in this area of law. But even an experienced subject matter specialist barely stands a chance against someone who really cares and invests himself as much as Michael.’

‘Experienced and knowledgeable. Supreme Court practice is a different creature. Paul Hughes in particular is a seasoned SCOTUS advocate, intellectually impressive and skilled advocate.’

‘Paul Hughes is wise. A skilled SCOTUS practitioner, I would go to him again if I wanted to take something to our nation’s highest court.’

‘Michael Kimberly gives you the attention he would if you were his only client. On top of his responsiveness, he is a wildly intelligent and strategic thinker. He is also known in amongst my industry peers for his brilliant writing.’

‘Incomparable expertise on administrative law matters, including immigration regulations.’

‘Paul Hughes is exceptionally professional, effective, and easy to work with.’

‘I have been very impressed by Andrew Lyons-Berg’s ability to apply big-picture thinking to his research and writing. He seems to instinctively understand how to research into odd corners of the law to find compelling support for his position, and he has a sophisticated view on how the executive branch operates. He is someone to watch closely.’

‘Mr. Hughes offered a way for us to take action against unjust policies. To me, he is a hero. He was exemplary and took time to teach us aspects of the relevant law. McDermott Will & Emery has a marvelous sense of collaboration and teamwork among partners. Mr. Hughes often referred to his collaboration with partner Michael B. Kimberly as offering pivotal, behind-the-scenes advice on how to frame the case and argue it.’

Similarly to Pattillo, Lamken has emerged as one of the most successful attorneys in patent cases at the Federal Circuit; he also recently presented arguments on behalf of Arthrex in Arthrex Inc. v Smith & Nephew Inc., a case in which the US Supreme Court seeks to examine the constitutional status as potentially ‘principal officers’ of US Patent and Trademark Office’s administrative patent judges.

Morrison & Foerster LLP

Described as ‘effective, engaged, and practical’, Morrison & Foerster LLP’s stable of appellate litigators is known for its astute handling of claims brought before numerous federal courts of appeal across the country. The department is spearheaded by Deanne Maynard and Joseph Palmore, with both being regarded as ‘a superb team for appellate matters’. Maynard is noted for her top performance in the Federal Circuit, as is Brian Matsui; this IP litigation excellence recently manifested itself in her presentation of winning arguments for Nevro Corp. in a high-stakes patent infringement dispute with Boston Scientific Corporation. The firm has a significant appellate strength on the West Coast; recently promoted partner James Sigel (San Francisco) places an emphasis on work in the Ninth Circuit and is also praised by clients for his brief writing skills. Just as importantly, the team is among the key players in the US Supreme Court, where a team led by Palmore and briefed by Sigel prevailed on behalf of the respondent in the employee-benefits case of Thole v U.S. Bank, N.A.

Practice head(s):

Deanne Maynard; Joseph Palmore

Other key lawyers:

Brian Matsui; James Sigel; Seth Lloyd; Lena Hughes


‘I have been impressed by MoFo’s efficiency and its competent junior lawyers. The appellate practice is small, but effective, engaged, and practical.’

‘Deanne Maynard and Joe Palmore are a superb team for appellate matters. And James Sigel is a true rising star in their San Francisco office.’

‘I recently hired Joe Palmore and James Sigel to handle a US Supreme Court argument for us and were very impressed with both of them.’

‘I have worked extensively with Brian Matsui and Seth Lloyd, both of whom are excellent thought-partners who are efficient, provide practical solutions, and have a collaborative mindset. I relish the opportunity to work with either of them again.’

‘James Sigel argued a Ninth Circuit appeal for us extremely well. He was one of four advocates, and the panel clearly thought that he was the best as they kept him up and asked him questions that went beyond the scope of our participation as an amicus.  He’s also done very well-written briefs for us, he always does a great job of keeping us up to speed on developments as they happen, and he’s a pleasure to work with.’

‘Joe Palmore and Deanne Maynard are well known. Deanne continues to excel at patent appeals in particular, and she and Joe are great at any appeals. Very knowledgeable with a great sense of strategy. Joe deserves a lot of credit for winning his ERISA case in the Supreme Court last year, as that was a very uphill battle for his side.’

‘James Sigel was able to come up with a very sophisticated argument strategy that I firmly believe won the day for us.’

‘Joe Palmore executed the argument flawlessly and the Court mirrored the language he thoughtfully chose in its ultimate order.’

Orrick, Herrington & Sutcliffe LLP

The ‘exceptional’ litigators at Orrick, Herrington & Sutcliffe LLP ‘clearly know the ins and outs of patent appellate litigation’; indeed, the practice has excellent depth in IP matters at the Federal Circuit. In one standout highlight of many, a team led by Joshua Rosenkranz, including Brian Goldman and Eric Shumsky (‘clear communicator, collaborator and strategist’), racked up a Federal Circuit victory for Gilead Sciences leading to the invalidation of a $2.54bn verdict, the biggest patent judgment to date. Elsewhere, building upon the firm’s prior success for Synopsys at district court level, a team led by the highly experienced Robert Loeb is acting for the client in an appeal at the Ninth Circuit seeking to establish whether the Department of Labor should comply with a request to disclose federal contractors’ annual employee demographic reports. Further, the group’s appellate attorneys are equally well versed in proceedings before the US Supreme Court; their recent work has been making headlines in light of the country’s growing interest in the regulation of the use of force exercised by police. Of recent note, the team acted for the petitioner in Torres v Madrid, a case in which the Roberts Court considered what constitutes a ‘seizure’ of a suspect under the Fourth Amendment. The department is spearheaded by New York-based Rosenkranz (‘great strategist, writer, and oral advocate’) and ‘excellent leaderMark Davies in Washington DC. Senior associate Jeremy Peterman is also recommended. Former practice co-leader Kelsi Corkran departed to embark on a pro bono senior fellow career in February 2021.

‘We engaged the team to assess the viabilities of a potential appeal. I, and others at our company, particularly appreciated how thorough, well-written, thoughtful, clear-eyed, and honest her written work product was.’

‘Good team organization. Maintained focus on key issues. The team worked well together. Excellent client interaction. Frequent and effective client communication. Willing to consider issues raised by others outside of their team.’

‘Josh Rosenkranz is an outstanding appellate lawyer. Excellent on analysis. Maintains focus on critical issues. Very strong on client involvement and interaction. Maintains effective organization of his team within the firm. Excellent writer and oral advocate. Brian Goldman did an outstanding job as Josh.’

‘They are client-focused. Bas de Blank is patient and responsive.’

‘We have worked with several different teams led by Josh Rosenkranz. They are excellent lawyers and writers and clearly know the ins and outs of patent appellate litigation. They are extremely collaborative with trial counsel and in-house counsel. One of our best appellate counsel.’

‘Josh Rosenkranz is the most incisive and creative appellate counsel I have worked with in recent years.’

‘The Orrick team is easy to work with. They are thoughtful, creative, and extremely quick to grasp complicated concepts. They got up to speed very quickly on complex legal and product issues, and were able to provide creative and helpful advice from our first conversation.’

‘The lead attorney, Eric Shumsky, is responsive and gives frequent updates. I also appreciate that he is not afraid to push back on suggestions or ideas that may undermine our position in the case, and advocate for the position he thinks is best for the case and for the company. Finally, he did a stellar job during the oral argument. He was very well-prepared and communicated our key points effectively in a very limited time frame.’

‘Eric Shumsky and his appellate team are top-notch. They are intellectual powerhouses, thinking through all the issues and crystallizing the arguments. Eric is a skilled orator and is quick on his feet to anticipate and respond.’

‘Eric Shumsky is an extremely talented lawyer. He is strong in both brief writing and oral argument. He is a clear communicator, collaborator and strategist with a thorough knowledge of the appellate practice.’

‘The team is exceptional, and Mark Davies is an excellent leader. They provide excellent representation. This is a team as good as any in other firms. Mark Davies and his colleagues leave no stone unturned. They are very strategic.’

‘Embedding Andrew Silverman in the trial team is key; in addition to being a superb writer, he is an appellate specialist and knows how to protect the record. Josh Rosenkranz is a great strategist, writer, and oral advocate. He knows how to cut through complexity to tell a compelling story. The team backing up Andrew and Josh is really excellent. And all of the appellate team members are incredibly responsive and pleasant to work with. They also work well with other firms and company executives, sometimes under trying circumstances.’

‘Jeremy Peterman is a standout among the associates. Great researcher and writer.’

‘The investment that Orrick put into the case we worked on together was exceptional. Although it seemed a long shot at the time as a Supreme Court case, they invested a huge amount of time and energy into debating each point of the cert petition, and it paid off with a victory in the Supreme Court that took many, including us, by surprise. Interpersonally, they were a pleasure to work with.’

‘Orrick stood out for how aggressively the firm staffed the case, how invested their associates were in the case, and how involved the supervising partner was, which is rare in our cases. The associates, Elizabeth Cruikshank and Tiffany Wright, were spectacular. Elizabeth is probably the best law firm associate I have ever worked with, and we work with many of these types of practices. The partner was not an absentee supervisor but deeply engaged with every aspect of the case and went through many drafts with us.’

‘Josh Rosenkranz led the team and did a masterful job. The quality of the written work was as good as I’ve seen anywhere, and Josh’s oral argument was first-rate.’

‘The Orrick appellate team helped us deftly navigate a tricky issue on appeal. They were thorough and practical, and I appreciated their attention to detail.’

‘Eric Shumsky is intelligent, pragmatic, creative, and a great partner.’

‘Mr. Robert Loeb was able to deal effectively with very difficult personalities to help us accomplish our goals. Mr. Loeb worked around the clock to help us achieve the settlement and literally saved our business.’

‘Ropes & Gray partner Douglas Hallward-Driemeier, a renowned SCOTUS oral advocate, has argued multiple cases, including Obergefell v Hodges, a landmark SCOTUS victory for the LGBT community, vindicating the freedom to marry for same-sex couples. He is not only a superb oral advocate, but also simply a warm, wonderful human being who has worked many long weekends, including holiday weekends, on our cases without complaint.’

‘Partner Kirsten Mayer has worked tirelessly, including over multiple holiday weekends, to provide briefing and strategic guidance to us at the highest level.’

‘Whether their work consists of an amicus brief on behalf of public health experts that requires mastery of complex scientific principles, or a brief articulating a visionary and precedent-setting constitutional argument seeking to correct an injustice for an individual plaintiff, their advocacy is consistently excellent. Ropes & Gray LLP is at the top of our list, second to none.’

‘We turn to Ropes & Gray when we wish to make high-stakes constitutional arguments for the first time. Although they are masters of doctrine, they can argue any case in a way that is human, moving, and compelling. Similarly, we have turned to Ropes & Gray when we have needed to file a complex case in short order. They are nimble and work extremely quickly to master a factual record, develop a narrative and strategy, and draft an excellent complaint. Although we have worked with different teams of partners and associates, each experience has been top-notch, and together we have won even the most challenging impact litigation cases.’

‘Douglas Hallward-Driemeier is a nationally renowned SCOTUS oral advocate, and extraordinary writer. Even though he has every reason to claim a big ego, he interacts with everyone in a manner that is completely ego-free. He is uniformly kind and respectful to attorneys, clients, and paralegals alike. His strategic thinking — whether about procedural or substantive matters — is visionary.’

‘Kirsten Mayer is a brilliant strategic thinker and writer, co-author of excellent briefing. We can count on Kirsten to deliver great advice. She also works tirelessly over weekends on our pro bono matters to develop the most comprehensive presentation possible in our cases.’

‘Jessica Soto is unflappable, even in four-alarm fires, and a consummate professional. She delivers excellent briefing, always on time. She gets to the heart of the issue immediately, and is skilled at interviewing clients and witnesses.’

‘Ethan Weinberg is a prodigious drafter, delivering briefing in extremely short time frames. Masters every detail of rules and makes the case run smoothly.’
