Operating Lease Commitments

In July 2011, the Company entered into a non-cancelable operating lease agreement to sublease approximately 32,000 square feet of office space located in San Francisco, California. The future minimum lease payments under the sublease totaled approximately $1.2 million as of December 31, 2011. The Company also leases approximately 30,000 square feet of additional office space in San Francisco, California under two separate, non-cancelable agreements, which commenced in August 2010 and December 2009. All of the office space leases in San Francisco expire in April 2013. In November 2010, the Company entered into a non-cancelable lease agreement for approximately 1,400 square feet of office space in Japan, which expires in August 2013. Rent expense related to these non-cancelable operating leases was $1.7 million, $733,000 and $352,000 for the years ended December 31, 2011, 2010 and 2009, respectively.

The aggregate future non-cancelable minimum lease payments for the Company's operating leases as of December 31, 2011 are as follows (in thousands):

Year Ending
2012	$	2,487
2013		949
Total future non-cancelable minimum lease payments	$	3,436

Litigation

From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with its legal counsel, the need to record a liability for litigation or contingencies. A liability is recorded when and if it is determined that such a liability for litigation or contingencies is both probable and reasonably estimable. No liability for litigation or contingencies had been recorded for the years ended December 31, 2011, 2010 and 2009.

Other Commitments

On September 10, 2010, the Company entered into certain agreements with a special-purpose entity formed for the sole purpose of acquiring specific patent assets that had been made available for sale by a third party. If the entity was successful in acquiring the patent assets, the Company had agreed to make a $5.0 million investment in the equity securities of the entity and serve as the exclusive licensing agent for the entity. As of December 31, 2011, the third party had completed the sale of the assets and the special-purpose entity was not the buyer. Therefore, no investment in such entity had been made and the Company has no further obligations under these agreements.

In December 2008, in connection with the acquisition of certain patent assets from an unaffiliated third party in an arm's-length transaction, the Company agreed to make a one-time payment of $5.0 million in the event that the Company earns $170.0 million of annual subscription revenues in any calendar year. No provision had been made for this contingent payment as of September 30, 2011. In October 2011, the underlying agreement with the unaffiliated third party was amended in exchange for a fixed payment of $4.0 million. Such payment was made in October 2011 and the contingent payment noted above and any related obligations were eliminated.

Guarantees and Indemnifications

The Company has, in connection with the sale of patent assets, agreed to indemnify and hold harmless the buyer of such patent assets for losses resulting from breaches of representations and warranties made by the Company. The terms of these indemnification agreements are generally perpetual. The maximum amount of potential future indemnification is unlimited. To date, the Company has not paid any amount to settle claims or defend lawsuits. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements since these obligations are not capped but are conditional to the unique facts and circumstances involved. Accordingly, the Company had no liabilities recorded for these agreements as of December 31, 2011 or 2010. The Company has no reason to believe that there is any material liability related to such indemnification provisions. The Company does not indemnify its clients for patent infringement.

The Company also, in accordance with its Amended and Restated Bylaws, indemnifies certain officers and employees for certain events or occurrences, subject to certain limits, while the officer or employee is or was serving at its request in such capacity. The term of the indemnification period is indefinite. The maximum amount of potential future indemnification is unspecified. The Company has no reason to believe that there is any material liability for actions, events or occurrences that have occurred to date.
