NEW YORK — Cartier sued Tiffany & Co. on Monday, accusing its luxury rival of stealing trade secrets concerning its high-end jewelry from an employee it lured away in December.
According to a complaint filed in a New York state court in Manhattan, Tiffany hired an underqualified junior manager away to learn more about Cartier’s “High Jewelry” collection, where pieces typically cost $50,000 to $10 million.
Cartier, a unit of Switzerland’s Richemont, called Tiffany’s hiring of Megan Marino a desperate bid to revive its own high jewelry unit after it was left in “disarray” following several departures, reflecting Tiffany’s “disturbing culture of misappropriating competitive information.”
According to court papers, Tiffany appeared to pin ultimate blame on Marino by firing her after just five weeks.
In an affidavit accompanying the complaint, Marino said Tiffany was “more interested in hiring me as a source of information than as a High Jewelry manager.”
Cartier also accused Tiffany of letting a recently hired former Cartier executive work on a high jewelry project called the “Blue Book” despite her six-month non-complete agreement.
Tiffany and its parent LVMH Moet Hennessy Louis Vuitton did not immediately respond to requests for comment.
The lawsuit seeks an injunction requiring that Tiffany return and not use stolen trade secrets, plus unspecified damages.
On Jan. 19, Richemont said strong demand for jewelry and watches following a trough earlier in the coronavirus pandemic boosted quarterly sales by 32%.
Sales at Richemont’s jewelry brands Cartier, Buccellati, and Van Cleef & Arpels rose 38%. — Reuters
