The K&L Gates Appellate Litigation practice handles important appeals affecting business, private clients, and public clients, ranging from overturning unfavorable and maintaining favorable trial results to addressing cutting-edge statutory, constitutional, and public-policy issues. Our lawyers have broad experience in the nuances of appellate practice, having argued cases in the United States Supreme Court, in all the United States Courts of Appeals, and in the appellate courts of most jurisdictions across the United States. Our lawyers combine exceptional written and oral advocacy skills with thorough substantive and procedural knowledge. We understand how high-profile disputes should be litigated and resolved, and we bring our collective experience to bear on every client matter.

The National Law Journal and Best Lawyers in America have recognized K&L Gates’ appellate practice as among the best in the nation.

For many litigants, the ultimate result comes down to an appeal. An appeals court can take away a hard-won victory or correct a harsh defeat. K&L Gates’ appellate lawyers combine impeccable research with a strong commitment to written composition of the highest quality and compelling oral-argument skills. We strive for clarity, concision, and cogency in making the kinds of arguments that matter on appeal to deliver results for our clients. Whether we serve as primary, consulting, or amicus counsel before an appellate court, our role can be crucial to achieving appellate success.

We frequently partner with our trial colleagues in high-stakes litigation to ensure that key appellate issues are introduced and appropriately preserved in the trial record. Our appellate record of success includes many published opinions dealing with matters of first impression as well as significant interpretations of precedent.

Clients frequently retain K&L Gates to provide representation as special appellate counsel and to draft amicus curiae briefs on behalf of publicly and privately held companies, government entities, nonprofits, and trade associations. Our awareness of amicus opportunities in the appellate courts has been valuable to clients that have needed to influence the development of the law in cases to which they are not parties. Because we understand how amicus briefs are most likely to influence a court, we avoid just repeating the arguments the parties have made and, instead, offer different perspectives that the court will find helpful.

Our appellate work has covered a wide variety of subject areas, including procedural issues such as jurisdiction, choice of forum, and evidentiary matters as well as highly complex substantive areas such as

  • employment
  • environmental liabilities
  • tort and product liability
  • intellectual property
  • consumer claims
  • financial services
  • insurance coverage
  • antitrust
  • bet-the-company contract disputes
  • immigration
  • tax
