Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

(a)
On December 19, 2012, the board of directors (the "Board") of Tessera Technologies, Inc. (the "Company") amended the Company's Amended and Restated Bylaws (the "Bylaw Amendment"). The Bylaw Amendment became effective immediately upon adoption by the Board and amended the Company's Amended and Restated Bylaws as described below.

In order to provide stockholders of the Company additional time to deliver notice of nominations of directors to the Board or to propose business to be brought before the 2013 Annual Meeting of stockholders of the Company (the "2013 Annual Meeting"), and consistent with the deadlines that had been applicable for past annual meetings of the Company, the Bylaw Amendment provides that for the 2013 Annual Meeting, a notice by a stockholder delivered to, or mailed and received at, the principal executive offices of the Company on or prior to February 15, 2013 will in all circumstances be deemed timely notwithstanding the date of the 2013 Annual Meeting or the date of the public disclosure thereof. Prior to the Bylaw Amendment, to be timely, such notice would have had to have been delivered, or mailed and received, no later than December 30, 2012.

The foregoing description is qualified in its entirety by reference to the text of the Bylaw Amendment, which is filed as Exhibit 3.1 hereto and incorporated herein by reference.
