Who's Who Legal Litigation: Lawyers

Constantine L Trela Jr chairs the Supreme Court and Appellate practice group in Sidley’s Chicago office and is one of the national leaders of the firm’s global Supreme Court and Appellate practice team. He served as a law clerk to Judge Robert Sprecher on the United States Court of Appeals for the Seventh Circuit and Justice John Paul Stevens on the United States Supreme Court. Mr Trela joined Sidley in 1981 and became a partner in 1986. Since joining Sidley, he has argued more than 75 cases in the US Courts of Appeals and State Supreme and Intermediate Appellate courts.

Mr Trela’s appellate practice covers a broad range of substantive areas, including patent and other intellectual property, product liability, insurance, commercial, and class action matters. Representative cases include: Lexmark Intl Inc v Ink Techs, in a case named to multiple “IP Cases to Watch” lists, the en banc Federal Circuit ruled 10-2 in favour of Firm client Lexmark on patent exhaustion issues related to foreign sales of US-patented products and domestic sales subject to a single-use licence; Shire Pharms v Johnson Matthey Pharmaceuticals, in which the Federal Circuit, in the first appellate decision to address the application of the safe harbour provision of the Hatch-Waxman Act to suppliers of pharmaceutical ingredients, reversed a summary judgment ruling holding Sidley client Johnson Matthey liable for patent infringement and entered judgment of non-infringement as a matter of law; and AstraZeneca AB v Apotex Corp, in which the Federal Circuit affirmed an award of approximately US$100 million in reasonable royalty damages against an “at-risk” generic entrant into the market.

WWL says: Constantine L Trela Jr is an “immensely skilled” lawyer who represents a broad range of clients in litigation including class action cases.
