Yahoo reportedly has notified potential buyers that it plans to auction off about 3,000 patents and will be accepting bids until mid-June. The intellectual property for sale includes patents for its original search technology. The patents "cover strategic areas such as search, e-commerce and online advertising," said Andreas Scherer, managing partner at Salto Partners. It's "very much like selling the crown jewels. It's safe to assume that the days of Yahoo as a standalone business are numbered."
