Yahoo is using its patent portfolio to proactively pressure Facebook in advance of the latter's pending IPO, according to Dunlap Codding shareholder Doug Sorocco.  In an article by Rachelle Dragani in E-Commerce Times on March 13, Sorocco was quoted as saying "The timing of this [lawsuit filed by Yahoo alleging patent infringement by Facebook] adds a pressure component, because anything that can decrease a valuation or depress a stock price will put tremendous pressure on Facebook to address this in some way."

Sorocco also explained that Yahoo had been an Internet trailblazer and had amassed a large patent portfolio.  The complaint filed by Yahoo mentioned its long history of innovation and asserted that Facebook had floundered before borrowing Yahoo's methods and systems for online advertising.
