Facebook paying Microsoft $550 million for 650 patents, Ballmer clicks 'like'

Microsoft has agreed to sell on around 650 patents to Facebook in a deal worth $550 million. The Haüs of Zuckerberg will stump up the cash in exchange for various social networking patents that were registered by AOL (disclaimer: Engadget's parent company) and sold to Redmond for $1 billion a fortnight ago. Microsoft will hold onto the remaining 275 in its portfolio and cross-license those that it's sold on, but not the 300 patents that AOL licensed but kept hold of. The social network will likely utilize the portfolio to better defend itself from litigation like the lawsuit brought by Yahoo back in March.

REDMOND, Wash. and MENLO PARK, Calif. - April 23, 2012 - Microsoft Corp. and Facebook announced today a definitive agreement under which Microsoft will assign to Facebook the right to purchase a portion of the patent portfolio it recently agreed to acquire from AOL Inc. Facebook has agreed to purchase this portion for $550 million in cash.

In the initial AOL auction, Microsoft secured the ability to own or assign approximately 925 U.S. patents and patent applications plus a license to AOL's remaining patent portfolio, which contains approximately 300 additional patents that were not for sale.As a result of today's agreement, Facebook will obtain ownership of approximately 650 AOL patents and patent applications, plus a license to the AOL patents and applications that Microsoft will purchase and own.

Upon closing of this transaction with Facebook, Microsoft will retain ownership of approximately 275 AOL patents and applications; a license to the approximately 650 AOL patents and applications that will now be owned by Facebook; and a license to approximately 300 patents that AOL did not sell in its auction.

"Today's agreement with Facebook enables us to recoup over half of our costs while achieving our goals from the AOL auction," said Brad Smith, executive vice president and general counsel, Microsoft. "As we said earlier this month, we had submitted the winning AOL bid in order to obtain a durable license to the full AOL portfolio and ownership of certain patents that complement our existing portfolio."

"Today's agreement with Microsoft represents an important acquisition for Facebook," said Ted Ullyot, general counsel, Facebook. "This is another significant step in our ongoing process of building an intellectual property portfolio to protect Facebook's interests over the long term."The parties are evaluating the accounting treatment for these transactions. These transactions are also subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.
