Re: Network Associates, Inc. – Trademark Matters

Mark: SNIFFERS

Dear Mr. Adams

Our client, the Board of Trustees of the Leland Stanford Junior University (“Stanford”), has asked that we respond to your letter of April 9, 2002, regarding the above.

We disagree that there is any likelihood of confusion between your client’s SNIFFER line of products and our client’s use of SSL Sniffer and SSL v.3/TLS Sniffer in connection with a non-commercial student project. As one of many factors indicating no likelihood of confusion, we note that the term “sniffer” is commonly used in the industry to refer generically to a type of program and/or device for network management or monitoring data traveling over a network. Your client’s mark lacks the inherent or acquired strength sufficient to overcome these facts.

We can confirm that our client has no plans to commercialize this student product under the SNIFFER name or mark.

We trust this responds to your inquiries. Please call if you have any questions.

Very truly yours,

Laura C. Gustafson
