Elyse Greenwald defends leading corporate clients in complex civil antitrust litigation in state and federal courts across the US.

Ms. Greenwald draws on extensive experience spanning multiple industries to help clients navigate complex commercial and antitrust litigation matters — including multidistrict litigation, class actions, and strategic business-to-business litigation — involving claims of:

  • Monopolization and attempted monopolization
  • Monopsonization
  • Price-fixing
  • Conspiracy
  • Refusal to deal
  • Predatory pricing
  • Fraud
  • State unfair competition laws

She has achieved significant victories for clients at every stage of litigation, including through dispositive motion practice, at trial, and through settlement.

A recognized leader at the firm, Ms. Greenwald serves on the Women Enriching Business (WEB) Committee.

Ms. Greenwald maintains a robust pro bono practice, including partnering with the Boston chapters of the ACLU, Lawyers’ Committee for Civil Rights, and NAACP LDF to challenge a Boston-area charter school’s discriminatory grooming policy. She also regularly represents clients in immigration proceedings.

Before joining the firm, Ms. Greenwald clerked for Judge Garland E. Burrell Jr. in the Eastern District of California and externed for Magistrate Judge Joseph C. Spero in the Northern District of California.

Ms. Greenwald’s matters include representing:

  • U.S. Sugar in a federal bench trial in the District of Delaware, in defense of a complaint brought by the Department of Justice (DOJ) to block U.S. Sugar’s proposed acquisition of Imperial Sugar Company under section 7 of the Clayton Act
  • CoStar Group against antitrust counterclaims brought by competitor Commercial Real Estate Exchange (CREXi), including monopolization and attempted monopolization of the markets for online commercial real estate information and listings, in which the district court granted CoStar’s motion to dismiss CREXi’s antitrust counterclaims with leave to amend
  • Ocean Spray Cranberries, in defense of an antitrust class action brought by cranberry growers; the court dismissed 10 of the 13 counts against Ocean Spray, denied plaintiffs’ motion for class certification, and granted Ocean Spray’s motion for summary judgment on plaintiffs’ monopolization claim
  • Surescripts, a pioneer of electronic prescribing, in securing a settlement with no monetary penalties in a US Federal Trade Commission lawsuit alleging monopolization of e-prescription markets through allegedly exclusionary contracts, as well as follow-on civil class action brought by classes of pharmacies
  • General Electric and GE Healthcare in a putative antitrust class action in which the plaintiffs alleged that GE monopolized the aftermarket for anesthesia services; Latham secured a confidential settlement following a successful motion to compel mediation

  • Oracle and NetSuite, in a weeklong federal jury trial in the Northern District of California, defending against claims of fraud brought by a former NetSuite customer; after excluding the plaintiff’s damages expert before trial, the jury returned a complete defense verdict for Oracle and NetSuite after deliberating for little more than an hour
  • Oracle in a putative class action in the Northern District of California in which the plaintiffs alleged that Oracle entered into agreements with other technology companies not to hire or solicit each other’s employees in violation of section 1 of the Sherman Act and California law; the court granted Oracle’s motion to dismiss with prejudice
