NEW YORK, June 27 (Reuters) - A U.S. bankruptcy judge on Tuesday approved Overstock.com's $21.5 million purchase of Bed Bath & Beyond's brand name, intellectual property and ecommerce platform. Overstock emerged as the winning bidder for the company's intellectual property in a deal worth $21.5 million, court filings showed on Thursday. Bed Bath & Beyond stores and inventory are not part of the deal. Bed Bath & Beyond is hosting a separate auction starting tomorrow for its Buy Buy Baby chain, which sells products for infants and toddlers. The Buy Buy Baby assets have attracted interest from investment firms Go Global Retail and Sixth Street Partners, according to media reports.
