A federal judge in Philadelphia has ruled that jewelry designer and manufacturer Michael Dawkins infringed on the trademark owned by jewelry designer and manufacturer Lagos.

U.S. District Court Judge Ronald J. Buckwalter of the Eastern District of Pennsylvania said that Philadelphia-based Lagos owns the trademark for the Caviar name in jewelry designs and that MDI must stop using the name in promoting and selling its own jewelry line—specifically rings, pins, bracelets, earrings, necklaces, and watches.

Lagos filed a civil suit in March against New York City–based MDI and Internet retailer ShopTwigs.com, charging that the jewelry manufacturer was promoting a line of jewelry using the Caviar name and selling the jewelry through ShopTwigs.com.

The court noted in its ruling that MDI had already stopped using the Caviar name in its advertising and distribution of jewelry and will not use the name in the future.

Complicating matters somewhat is that MDI filed for Chapter 11 bankruptcy protection on Aug. 2. Lagos said MDI is still liable for any infringement on its trademark after the filing. The court agreed.
