The two companies have been locked in a bitter feud ever since LVMH, which owns Louis Vuitton and dozens of other luxury brands, revealed that it had secretly built up a 17-percent stake in the family-dominated Hermes.
LVMH, led by tycoon Bernard Arnault, later built this holding up to 22.6 percent prompting Hermes to cry foul and accuse Arnault of surreptitiously trying to add Hermes to his large stable of brands.
Hermes demands that LVMH sell back the stock to the three banks -- Societe Generale, Natixis and Credit Agricole -- which are themselves accused in court of acting as de-facto fronts for the alleged takeover attempt.
The courtroom battle is the latest in a barrage of legal proceedings launched by Hermes against LVMH, whose spokesman told Les Echos that the accusations by Hermes were unfounded and part of wider slander campaign.
