- Represented a leading technology company to assume the defense of a lawsuit that prior counsel had lost at trial, which had resulted in an eight-figure jury verdict against the company. On behalf of the client, Harry won a motion for a judgment notwithstanding the verdict and for a new trial successfully defeated plaintiff's claim for violation of the California Unfair Competition law following a bench trial. He then successfully defended the trial court judgment that he obtained for the client in appellate proceedings before the California Court of Appeal.
- Represented B/E Aerospace as part of the Irell & Manella LLP team that successfully obtained a summary judgment of noninfringement in a patent lawsuit against Irell's client, and then obtained a published appellate affirmance of that summary judgment from the U.S. Court of Appeals for the Federal Circuit.
- Represented a leading technology company in litigation against a competitor and certain former employees involving claims for misappropriation of trade secrets and breaches of fiduciary duty. Using the anti-SLAPP statute, Harry successfully defeated various counterclaims for defamation that had been asserted against his client, first by obtaining a trial court order of dismissal, and then by obtaining a trial court order awarding his client a six-figure attorneys’ fee award as the prevailing party.
- Represented a number of the nation's leading motion picture studios and television networks in copyright, trademark, right of publicity/privacy, unfair competition and contract disputes.
- Represented a leading international law firm on appeal, obtaining a published appellate affirmance of a judgment dismissing claims for alleged professional negligence. The published decision held, as a matter of first impression under California law, that a legal malpractice lawsuit must be dismissed where the law firm could not effectively defend the suit without revealing privileged client confidences.
