Tamar Lusztig

Tamar Lusztig represents plaintiffs and defendants at trial and on appeal in federal and state courts across the country. Tamar is a seasoned trial lawyer with substantial courtroom experience, representing her clients in a wide variety of matters regarding intellectual property, antitrust, contracts, employment, products liability, and other high-stakes, complex cases.

Tamar has amassed an impressive docket of high-profile cases, often facing off – and prevailing – against opponents with substantially more resources than her clients. Tamar’s clients and colleagues look to her for her strategic acumen, judgment, and composure under pressure to help secure victory in bet-the-company cases.

Recent Successes

  • Tamar is currently prosecuting multiple class actions for victims of child pornography in groundbreaking lawsuits against PornHub, its parent company MindGeek, and Reddit.

PornHub’s efforts to escape the case against it was recently rejected by a California federal judge.
  • Tamar represents a putative class of municipalities in an antitrust dispute brought against numerous major banks related to their price-fixing of bond rates.

  • Tamar achieved victory for a research hospital in a confidential AAA arbitration with a major international pharmaceutical company regarding a patent licensing dispute. Tamar cross examined each fact witness her adversary presented, obtaining testimony the Tribunal relied on heavily in its decision securing Tamar’s client a multi-million-dollar award.
  • Tamar successfully prosecuted a patent infringement case against AT&T over pioneering Internet technology invented by Tamar’s client. Tamar briefed, argued, and won multiple motions, including a critical claim construction motion in which the Court adopted all of her client’s positions.

  • Tamar represented PMC, the owner of one of the world’s most valuable patent portfolios, in a week-long jury trial against Google. Tamar briefed, argued, and won numerous critical pre-trial motions. At trial, Tamar put on the 4-hour direct exam of her client’s primary liability expert, as well as cross examining Google engineers.
  • Tamar represented an insurance company in a confidential nine-figure dispute with one of its insureds about the scope of coverage. The case settled on confidential terms shortly before a scheduled AAA arbitration.
