At least half a dozen defunct department stores will get a second lease on life.

A six-year legal battle between Macy’s — which owns more than 20 trademarks for departed chains, including Marshall Field’s, Abraham & Straus and Bon Marché — and California-based Strategic Marks was settled, giving the latter the rights to six brand names.

Terms of the settlement were not disclosed, but Strategic Marks won Jordan Marsh, I. Magnin, Bamberger’s, Foley’s, Robinson’s May Company and Bullock’s.

“These brands had been locked up so tightly, but we were able to show that Macy’s had no intention of using them,” said Ellia Kassoff, chief executive of Strategic Marks, which had acquired the names and was later sued by Macy’s.

Kassoff plans to relaunch the stores initially as a virtual mall at www.refashionmall.com — and eventually open physical stores.

Macy’s said it retained all rights to its “other heritage store brand marks.”
