Stratagene Responds to Damages Awarded in Invitrogen Lawsuit.

Stratagene Intends to Appeal the Decision

Competent Cells Patent At Issue

LA JOLLA, Calif. -- Stratagene Corporation (NASDAQ:STGN), a developer, manufacturer and marketer of specialized life science research and diagnostic products, announced today that the federal judge overseeing Invitrogen Corporation vs. Stratagene in the United States District Court for the Western District of Texas has awarded Invitrogen $16.2 million in damages plus pre-judgment interest and ruled that Stratagene must pay Invitrogen's attorney's fees, in an amount to be determined by the court. On July 25, 2006, the jury determined that Invitrogen's 4,981,797 patent is valid and that Stratagene infringed that patent by making and selling its competent E. coli cell products. The jury decided to award Invitrogen a 15% royalty rate on sales between the years 1997 and 2004 (for a total of $7.9 million in damages) and found Stratagene to have willfully infringed the patent only between the years 1997 and 2001.

Stratagene believes that the jury's verdict and the damages awarded were not supported by the facts of the case or the law and as a result, the Company intends to appeal the decision. In appealing the jury's verdict and the court's subsequent post trial rulings, Stratagene will be challenging the finding of validity of the patent, the appropriateness of the damages determined by the jury, the trebling of a portion of the amount by the court and the award of attorney's fees.

Stratagene had previously modified its process for manufacturing competent E. coli cell products and, as a result, Invitrogen has agreed that Stratagene products sold in recent years and currently offered for sale will not be affected by the jury verdict. The jury found that Invitrogen was not entitled to lost profits because Stratagene has had a non-infringing manufacturing process for competent cells.

The action by Invitrogen was initiated in March 2001. In November 2001, the district court granted Stratagene's motion for summary judgment finding that Invitrogen's aforementioned patent was not infringed by Stratagene. Upon Invitrogen's appeal, the United States Federal Circuit Court of Appeals reversed the lower court's decision in part and remanded the case back to the lower court. In January 2004, the district court granted partial summary judgment to Invitrogen based on the determination that Stratagene's then-existing manufacturing process infringed Invitrogen's patent, however the court also determined that Invitrogen's patent was invalid. Stratagene then changed its manufacturing process for competent cell products to a non-infringing method. Invitrogen appealed the decision again and in October 2005 the Federal Circuit Court reversed the district court's findings in part. The case was remanded back to district court, resulting in the jury's determination handed down on July 25, 2006 followed by the court order issued on October 31, 2006.

The Company currently has approximately $16.6 million in unrestricted cash and a $9.0 million revolving line of credit in place which has a zero balance currently outstanding. The Company's operations remain cash flow positive. The total amount of long-term debt is approximately $3.8 million and final payments on such long-term debt are not due until 2022.
