Jimi Hendrix stole the show at an intellectual property auction held Thursday in downtown New York.

About 400 venture capitalists, inventors, spectators and attorneys from the likes of BellSouth Corp., AT&T Corp., Nike Inc., NEC Corp. and IBM Corp. gathered to buy and sell patents, trademarks, domain names and copyrights — including the rights to all of Hendrix’s music. The auction, organized by Chicago-based IP group Ocean Tomo LLC, was held in the former Bowery Savings Bank, a landmark 19th-century Beaux Arts building that is now a posh events space.
