     This Amendment No. 9 to Schedule 13D ("Amendment No. 9") amends the
Schedule 13D filed on March 5, 2007 (as amended by Amendment No. 1 thereto filed
on March 21, 2007, Amendment No. 2 thereto filed on April 11, 2007, Amendment
No. 3 thereto filed on April 18, 2007, Amendment No. 4 thereto filed on May 22,
2007, Amendment No. 5 thereto filed on May 31, 2007, Amendment No. 6 thereto
filed on July 17, 2007, Amendment No. 7 thereto filed on August 30, 2007,
Amendment No. 8 thereto filed on October 17, 2007 and this Amendment No. 9, the
"Schedule 13D") and is being filed on behalf of Third Point LLC, a Delaware
limited liability company (the "Management Company" or "Third Point"), and
Daniel S. Loeb, an individual ("Mr. Loeb", and together with the Management
Company, the "Reporting Persons"). This Amendment No. 9 relates to the common
stock, par value $0.01 per share (the "Common Stock"), of PDL BioPharma, Inc., a
Delaware corporation (the "Company").

     The Management Company is the investment manager or adviser to a variety of
hedge funds and managed accounts (such funds and accounts, the "Funds"). The
Funds directly owned the Common Stock to which this Schedule 13D relates, and
Mr. Loeb and the Management Company may have been deemed to have beneficial
ownership over such Common Stock by virtue of the authority granted to them by
the Funds to vote and to dispose of the securities held by the Funds, including
the Common Stock.

Item 5.   Interest in Securities of the Issuer.

     Items 5(a), 5(c), 5(d) and 5(e) of the Schedule 13D are hereby amended and
restated as follows:

     (a) As of the date hereof, the Management Company and Mr. Loeb beneficially
own no shares of Common Stock.

     (c) Schedule A hereto sets forth certain information with respect to
transactions by the Funds (at the direction of the Management Company and Mr.
Loeb) in the Common Stock since the most recent filing on Schedule 13D.

     All of the transactions set forth on Schedule A were effected in open
market transactions in the NASDAQ Global Select Market. Except as set forth on
Schedule A, since the most recent filing on Schedule 13D there were no
transactions in the Common Stock effected by either the Management Company nor
Mr. Loeb, nor, in the case of the Management Company, to the best of its
knowledge, any of their directors, executive officers, general partners or
members.

     (d) Other than the Funds which directly held the shares of Common Stock,
and except as set forth in this Item 5, no person is known to have the right to
receive or the power to direct the receipt of dividends from, or the proceeds
from the sale of, the shares of Common Stock.

     (e) The Management Company and Mr. Loeb ceased to be the beneficial owner
of more than five percent of the outstanding Common Stock on October 30, 2007.

complete and correct.
