ITEM 5.  OTHER EVENTS.

         Paul Ryan, Chairman and Chief Executive Officer of Acacia Research
Corporation, previously established a plan under Rule 10b5-1 of the Securities
and Exchange Commission, to provide for pre-determined sales of a portion of his
Acacia Research common stock.

         The purpose of the plan was to provide proceeds to pay federal and
state tax obligations resulting from Mr. Ryan's exercise of Acacia Research
stock options during 2001. Under the plan, an average of 4,000 shares were to be
sold each week beginning December 24, 2001, subject to minimum share price
restrictions, until sufficient funds were generated.

         Additional sales of Mr. Ryan's Acacia Research common stock have been
made outside of the plan when the minimum share price restrictions of the plan
were not met. Sufficient funds have now been generated by the plan and non-plan
sales to pay Mr. Ryan's tax obligations. Accordingly, Mr. Ryan has terminated
the plan, and no further transactions will occur thereunder.

         Mr. Ryan has been a director of Acacia Research since 1995, Chief
Executive Officer since 1997 and Chairman since 2000.
