Wilson Sonsini Goodrich & Rosati has developed a respected, accomplished appellate practice through its successful representation of corporate clients before federal and state appellate courts. The firm's appellate attorneys have prevailed in high-profile cases involving significant issues of law, particularly in antitrust, consumer fraud, intellectual property, and securities litigation matters. Our appellate attorneys have also litigated landmark Internet and privacy law cases.

WSGR has represented clients before the U.S. Supreme Court and all of the federal courts of appeals, including the Federal Circuit and the Patent Trial and Appeal Board. In addition, our attorneys have represented clients before state appellate and supreme courts.

The firm has earned substantial recognition from peers and jurists alike by consistently securing favorable outcomes in the Ninth Circuit and the Federal Circuit. Our appellate attorneys have also had significant success in the First, Second, Third, Fourth, Fifth, Seventh, Eighth, Tenth, Eleventh, and D.C. Circuits, as well as the state supreme courts of California, Delaware, Idaho, and Indiana.

The firm's appellate team is led by Boris Feldman, who has represented clients in more than 200 lawsuits throughout the United States. Other appellate attorneys include:

  • Susan Creighton, a widely respected antitrust specialist who clerked for U.S. Supreme Court Justice Sandra Day O'Connor;
  • Cheryl Foung, who has prosecuted or defended more than 25 securities class action appeals, shareholder derivative appeals, and writs since she has been at the firm.
  • Jonathan Jacobson, a recognized antitrust expert who co-authored the respondents' brief in the landmark U.S. Supreme Court case Eastman Kodak v. Image Technical Services;
  • Gideon Schor, who litigated more than 200 civil appeals as Chief Appellate Attorney at the U.S. Attorney's Office for the Southern District of New York and who petitioned for certiorari and argued before the U.S. Supreme Court in U.S. ex rel. Eisenstein v. City of New York, concerning appellate jurisdiction;
  • Richard Torczon, a former Administrative Patent Judge at the Patent Trial and Appeal Board;
  • Jose Villarreal, who has appeared before the Federal Circuit in cases involving matters of first impression under the America Invents Act; and
  • Brian Willen, who has been involved in significant IP and Internet law litigation, including the widely followed Viacom v. YouTube case.

Prior to becoming accomplished litigation and administrative agency practitioners, many of the firm's appellate attorneys served as law clerks in federal and state appellate courts. They draw upon their respective clerkship experience in the course of representing clients in appellate matters. Collectively, the firm's appellate attorneys have briefed and argued hundreds of matters.

Our appellate attorneys often represent clients from the earliest stages of litigation, well before matters are heard by lower courts or administrative tribunals. Their familiarity with the facts, legal issues, and parties in the dispute becomes an advantage if matters proceed to appeal. Even when not directly involved in representing a given client at the lower level, they work closely with their colleagues handling the matter to formulate strategies, craft possible arguments, and address key issues should the dispute advance toward an appeal.

WSGR's appellate attorneys are also accustomed to being retained by corporate counsel and other law firms when our firm was not involved in representing clients during the dispute's early stages or was not counsel of record in lower-court or administrative proceedings.

By applying their subject-matter expertise and devising novel, effective arguments, the firm's appellate attorneys have played a significant role in shaping case law, including decisions interpreting federal and state statutes and administrative law and procedure.
