of the following documents:

1. Plaintiff Celerity, Inc.’s Motion in Limine No. 2 to Exclude the Testimony of Steven

3. Exhibits B, C, E, and BB to the Declaration of Keith L. Slenkovich in Support of

Celerity, Inc.’s Motions in Limine.

With respect to the remaining documents plaintiff seeks to file under seal,

specifically, Exhibits M-S to the Declaration of Keith L. Slenkovich in Support of Celerity,

Inc.’s Motions in Limine, the Court DEFERS ruling on the motion, because an insufficient

showing has been made. Each of said exhibits is an opinion letter to defendants from their

opinion counsel as to the issue of infringement and/or invalidity of plaintiff’s patents. 

Although such letters presumably were covered by the attorney-client privilege at one time,

any claim of privilege was waived when defendants disclosed such letters to plaintiff. If,

however, defendants can establish some other basis for a finding of confidentiality as to

said exhibits, either in their entirety or in part, defendants may file, no later than May 15,

2007, a declaration setting forth such basis. See Civil L.R. 79-5(d) (providing where party

seeks leave to file under seal document designated as confidential by another party,

designating party must file declaration setting forth reasons why such document is

confidential). If defendants fail to file such a declaration, the Court will direct the Clerk to

file Exhibits M-S in the public record.

IT IS SO ORDERED.
