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.

  • Tamar won a $31.5 million jury victory on behalf of Dutch telecommunications company Koninklijke KPN N.V. (“KPN”) against Swedish giant Ericsson over patent infringement claims relating to telecommunications networks. Tamar put on KPN’s entire damages case, including directing the examination of KPN’s expert and cross examining Ericsson’s damages expert. The successful verdict concluded a more than five-year dispute between the companies, with the jury awarding KPN the entire damages model outlined by Tamar and her team, plus finding willfulness.

  • Tamar represented New York University in a lawsuit brought by FASORP, a Texas organization that claims the university discriminates against white men in its efforts to foster diversity in its faculty and on the NYU Law Review. Tamar briefed and won her client’s motion to dismiss before the district court, and briefed, argued and won the appeal before the United States Court of Appeals for the Second Circuit. You can read the Second Circuit’s precedential decision here, listen to Tamar’s winning argument here, and read more about the case herehereherehere, and here.
  • 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. This case settled on favorable, confidential terms soon afterwards.
  • 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.
  • Tamar represented a former prisoner in a Section 1983 case arising out of an illegal strip search during her incarceration. Key admissions Tamar obtained in the defendants’ depositions led to a sizeable settlement for her client on the eve of trial.

Tamar is the first woman (among two) to be elected to the Susman Godfrey partnership in New York, and serves as co-chairperson of the firm’s Diversity Committee.
