Goss Int’l Am., Inc. v. Graphic Management Assocs., Inc., No. 05 C 5622, 2007 WL 161684 (N.D. Ill. Oct. 9, 2007) (Valdez, Mag. J.).*

Magistrate Judge Valdez granted in part the parties’ cross motions to compel various discovery. Each party’s alleged waived privilege is of particular interest. The Court denied plaintiff’s motion to compel all documents reflecting defendants’ trial counsel’s** mental impressions of the case, whether or not they were shared with defendants. In light of In re Seagate, the Court held that defendants’ reliance upon advice of counsel does not waive its privilege as to trial counsel’s mental impressions not communicated to defendants. 

The Court denied in part defendants’ motion to compel all previously privileged documents related to prosecution of the patent in suit. Defendants alleged that plaintiff’s production of a Record of Invention document prepared by the inventors at counsel’s direction and request waived privilege. The Court held that plaintiff intentionally waived privilege by disclosing the document, but limited the waiver to documents related to development of plaintiff’s invention.

** It is not entirely clear, but it appears from the opinion that defendants used the same firm or attorneys for both opinion counsel and trial counsel.
