Christine Zaleski is a versatile litigator who represents clients in complex commercial disputes, with a particular focus on defending technology companies in intellectual property matters. Her practice spans high-stakes contract, unfair competition, copyright, false advertising, and trade libel cases, as well as the defense of professional malpractice and fraud claims. Her matters often involve complex factual records, novel legal issues, and business-critical technology. She has played key roles in securing favorable settlements, narrowing claims on summary judgment, and positioning cases for trial.
Reflecting the breadth of her practice, Christine has defended clients facing significant reputational and financial exposure, including law firms and executives accused of malpractice and related torts. She successfully defended a prominent law firm against malpractice claims brought by investors in a company that was later revealed to be a Ponzi scheme and defended a client in a criminal investigation that resolved favorably before any charges were filed. She also represents biotechnology clients, including early-stage life sciences companies, in disputes arising from complex collaboration and licensing agreements.
Prior to joining Keker, Van Nest & Peters, Christine served as a law clerk to Judge Christopher F. Droney of the U.S. Court of Appeals for the Second Circuit. She was formerly a litigation associate with a private public interest firm in Boston, where she briefed and argued cases in state and federal court and before the U.S. Court of Appeals for the First Circuit. She is also a former law clerk to Judge F. Dennis Saylor IV of the U.S. District Court for the District of Massachusetts.
Christine graduated cum laude from Harvard Law School and earned her B.A. in environmental studies, magna cum laude, from Brown University.
Calithera Biosciences, Inc v. Incyte Corp.
We represented Calithera Biosciences, an early-stage drug development company, in a milestone dispute arising out of a collaboration agreement. We obtained a favorable settlement before depositions began.
RingCentral, Inc. v. Nextiva, Inc.
We represented Nextiva, Inc., as defendant and counterclaimant in a trade libel, defamation, and false advertising suit. We succeeded in significantly narrowing the case against Nextiva on summary judgment and then favorably resolved the remainder of the litigation on the eve of trial.
CoStar v. CREXi
We represented Commercial Real Estate Exchange, Inc. (CREXi), a fast-growing online commercial real estate marketplace, in competitor litigation against industry giant CoStar. After CoStar filed a complaint against CREXi alleging copyright violations, we asserted antitrust counterclaims–—supported on appeal by the FTC—alleging that CoStar is an unlawful monopolist. We convinced the Ninth Circuit to reverse its dismissal of our antitrust claims in a unanimous, published opinion.
DC Solar Investors v. Law Firm
We defended a prominent law firm and one of its senior partners against legal malpractice and fraud actions in California federal court, Los Angeles Superior Court, and U.S. Bankruptcy Court. The firm had served as tax opinion counsel in connection with a series of tax-sheltered investments in a solar business that turned out to be a Ponzi scheme. After years of litigation, we negotiated a successful settlement between the firm and the solar company investors. We also negotiated a successful settlement between the law firm and the Trustee for the consolidated estates of the company and its subsidiaries.
