Case No. 07-cv-00633

BCD SEMICONDUCTOR CORPORATION, et al., Defendants.

REDACTED

SUPPLEMENTAL DECLARATION OF ROBERT BLAUSCHILD I, Robert Blauschild, declare as follows:
1. I have been retained by Power Integrations as an expert witness in this

matter. I have acted as an expert witness for Power Integrations in previous matters, including the Power Integrations v. Fairchild matter in this Court.

2.

I have worked extensively in the field of analog and mixed-signal circuit

design, including over 30 years of advanced integrated circuit ("IC") design work. I have worked on and consulted on designs for a wide range of analog and mixed-signal circuits, and the cumulative sales of commercial products I have designed is now well above $250 Million.
3. I have reviewed BCD's opposition to Power Integrations' motion for

preliminary injunction, Dr. Habetler's accompanying declaration and exhibits, and the transcript from Dr. Habetler's deposition. None of the arguments BCD and Dr. Habetler have set forth in these materials changes my opinion that BCD infringes Claim 1 of the '876 patent, and in my opinion they do not provide any serious challenge to the validity of Claim 1 of the '876 patent.

5.

Dr. Habetler's arguments regarding infringement do nothing to change my

opinion that BCD's products infringe Claim 1 of the '876 patent, and the materials BCD has provided since my first declaration confirm that BCD's devices do, in fact, infringe. Specifically, I have reviewed the schematics provided for the AP3700/A, AP3700E, and AP3710, and each of these products infringes Claim 1 of the '876 patent for the same reasons I explained in my original declaration. 6.

16.

As with infringement, Dr. Habetler's arguments regarding validity do not

change my opinion that Claim 1 of the '876 patent is valid. Dr. Habetler's declaration makes a number of arguments regarding validity, though, so I address the relevant points in turn.

19.

Dr. Habetler also ignores the wide range of secondary considerations

evidence demonstrating that the patented frequency jitter of the '876 patent is in fact valid, including my detailed testimony on this point during the Fairchild case. 20. Therefore, I still conclude that the AP3700, AP3700A, AP3700E, and

AP3710 chips contain each and every claim limitation of Claim 1 of the '876 patent and that the patent is valid.

I declare under penalty of perjury under the laws of the United States of America that the foregoing is true and correct. Executed this 7+k- day of May, 2008, at Los Altos, CA.
