ORDER
The Regents of the University of California (“UC”) petition for a writ of mandamus to the United States District Court for the Southern District of Indiana, to vacate the court’s July 2, 1996 order 1 granting Genen-tech, Inc.’s motion to compel the deposition testimony of three attorneys employed by Eli Lilly and Company.
Judicial orders may be overturned by extraordinary writ only when there has been a clear abuse of discretion or usurpation of judicial authority in the grant or denial of the order.
In re The Regents of the University of California,
Genentech argues that discovery orders are not routinely appealable. However, the issue before us is not a routine discovery dispute, but one of attorney-client privilege. A writ of mandamus may be sought to prevent the wrongful exposure of privileged communications. As stated in
Harper & Row Publishers, Inc. v. Decker,
The district court ruled that the attorney-client privilege was waived, or never vested, when the Eh Lilly attorneys provided legal advice and services to UC. This is “not a mere discretionary [ruling] but rather turns on legal questions appropriate for appehate review.”
In re Burlington Northern, Inc.,
This petition arises in connection with consolidated pretrial proceedings in the Southern District of Indiana, established • by the Judicial Panel on Multidistrict Litigation in
In re Recombinant DNA Technology Patent and Contract Litigation,
Docket No. 912 (J.P.M.L. Feb. 19, 1992),
aff'd, In re The Regents of the University of California,
In the case in which this petition originated Genentech seeks a declaration that UC’s United States Patent No. 4,363,877 (the ’877 patent) is invalid, unenforceable, or not infringed by Genentech’s production of hGH products. Genentech sought the discovery depositions of three Lilly , in-house attorneys relating to the prosecution of the ’877 patent and its counterparts in foreign countries. The district court ordered the testimony, but stayed completion of this discovery pending this appeal.
Meanwhile, on September 27, 1996 the district court dismissed the declaratory action that had been brought by Genentech (IP-90-1679-C), granting UC’s renewed motion for summary judgment on Eleventh Amendment grounds. The district court then requested the Judicial Panel on Multi-district Litigation to remand the remaining action, IP-92-0223-C, to the Northern District of California for trial. The district court stated that “because the two cases are mirror images, the discovery that has taken place in IP-90-1679-C fully is. applicable to IP-92-0223-C.” Slip op. at 16. The Multi-district Panel issued a Conditional Remand Order on October 4, 1996; Genentech states that it has opposed the remand order on the ground that this discovery is incomplete, thus delaying the order’s effectiveness, in accordance with Rule 14(f)(ii) of the Panel.
On October 15, 1996 the Federal Circuit ordered UC and Genentech to advise whether this mandamus petition should appropriately be dismissed in view of the district court’s action. UC and Genentech are of one mind in opposing dismissal. They point out that the discovery to which this petition.is directed is applicable whether or not the consolidation of pre-trial procedures is otherwise terminated, and that completion of the challenged discovery was stayed pending this appeal.
Taking note of the stay in conclusion of the multidistrict proceedings, we agree that we have not been divested of jurisdiction of the petition. For the reasons discussed we grant the writ of mandamus.
DISCUSSION
On April 19, 1978 UC filed the United States patent application that led to the .’877 patent. In September 1978 UC and Lilly entered into an exclusive option agreement for certain license rights to ensuing United States and corresponding foreign patents; *1389 the license would become exclusive upon certain conditions subsequent. Those conditions did occur and the license became exclusive. Lilly agreed to pay the foreign patent costs, and in 1984 Lilly in-house attorneys assumed direct responsibility for prosecuting the foreign patent applications, in collaboration with UC patent counsel. Genentech is seeking to discover the legal advice that was given and that relates to the United States ’877 patent.
According to Genentech, the UC and Lilly attorneys frequently discussed certain prior art, which Genentech alleges is material to the ’877 United States patent. Genentech states that testimony about those communications is relevant to the issue of inequitable conduct. Genentech also seeks testimony from a Lilly attorney about his investigation and advice to UC concerning errors in the ’877 patent, which led to UC’s application for a Certificate of Correction. Genentech states that obtaining the Certificate of Correction also involved inequitable conduct by UC.
Genentech argues that an attorney-client communication is not privileged if it is shared with a third party, and that Lilly was a third party despite its status as optionee/licensee. UC responds that the Lilly attorneys represented both UC and Lilly in a shared effort to obtain these United States and foreign patent rights, and that the communications between UC and the Lilly attorneys were protected by the attorney-client privilege. The district court held that “the UC-Lilly relationship arising from the option agreement created no need for a common defense” because “[t]he entities were prosecuting patents, and at that point, apparently were bound only by the prospects of financial gain and heightened reputation.” The district court concluded that UC and Lilly did not share the requisite community of interest to allow UC to invoke attorney-client privilege as an exception to the general rule favoring full discovery. ,
The Community of Interest Doctrine
When the same attorney represents the interests of two or more entities on the same matter, those represented are viewed as joint clients for purposes of privilege.
See Simpson v. Motorists Mutual Ins. Co.,
The protection of communications among clients and attorneys “allied in a common legal cause” has long been recognized. As one court explained:
[Wjhere there is consultation among several clients and their jointly retained counsel, allied in a common legal cause, it may reasonably be inferred that resultant disclosures are intended to be insulated from exposure beyond the confines of the group; that inference, supported by a demonstration that the disclosures would not have been made but for the sake of securing, advancing, or supplying legal representation, will give sufficient force to a subsequent claim to the privilege.
In re Grand Jury Subpoena Duces Tecum,
UC argues that it and Lilly were, in the circumstances that here obtained, both clients of the Lilly lawyers, and that UC and Lilly shared a common legal interest in gaining sound patent rights to this technology, *1390 which had been developed by UC and optioned and licensed by Lilly. UC also cites the fact that from the inception of the option agreement, Lilly’s license rights had the potential to become and ultimately did become exclusive and that that fact gave Lilly and UC an identity of interest. Thus UC argues that its communications with the Lilly attorneys are subject to the attorney-client privilege, along with Lilly’s work product on behalf of UC.
Genentech argues- that UC and Lilly lacked the requisite common interest for the attorney-client privilege to attach to the communications between UC and the Lilly attorneys. Genentech also argues that UC was not a client of the Lilly in-house attorneys. Indeed, the Lilly attorneys testified that they considered Lilly, and not UC, to be their “client.” However, the issue is not who employed the attorney, but whether the attorney was acting in a professional relationship to the person asserting the privilege. “The professional relationship for purposes of the privilege for attorney-client communications ‘hinges upon the client’s belief that he is consulting a lawyer in that capacity and his manifested intention to seek professional legal advice.’ ”
Westinghouse Elec. Corp. v. Kerr-McGee Corp.,
The Lilly attorneys advised and consulted frequently with UC counsel on matters relating to UC?s patents. It is not disputed that the Lilly attorneys received confidential information from UC and gave legal advice to UC. However, Genentech argues that even if UC were deemed to be a “client” of the Lilly attorneys, Lilly and UC lacked a common legal interest because UC was the inventor/patentee and Lilly was an optionee and a potential licensee. As we have discussed, in order for the communications between UC and the Lilly attorneys to be protected by the attorney-client privilege, Lilly and UC as clients must share a common legal interest, or have a community of interest, with respect to the subject of the communications. The district court held that the community of interest standard required that “the nature of -the interest be identical, not similar, and be legal, not solely commercial,” citing
Duplan Corp. v. Deering Milliken, Inc.,
Accepting that the scope of the attorney-client privilege is narrowly drawn in the Seventh Circuit,
2
we conclude that the legal interest between Lilly and UC was substantially identical because of the potentially and ultimately exclusive nature of the Lilly-UC license agreement. Both parties had the same interest in obtaining strong and enforceable patents. The district court erred in concluding that Lilly and UC did not have an identical legal interest in the ’877 patent and its foreign counterparts because “a pat-entee and a nonexclusive licensee do not share identical legal interests.” Lilly was more than a non-exclusive licensee, and shared the interest that UC would obtain valid and enforceable patents. UC is a university seeking valid and enforceable patents to support royalty income. Lilly is an industrial enterprise seeking valid and enforceable patents to support commercial activity. Valid and enforceable patents on the UC inventions are in the interest of both parties.
See Duplan,
Genentech also contends that the communications between UC and the Lilly attorneys are not covered by the privilege because they were not made in anticipation of litigation. It is well established that the attorney-client privilege is not limited to actions taken and advice obtained in the shadow of litigation. Persons seek legal advice
*1391
and assistance in order to meet legal requirements and to plan their conduct; such steps serve the public interest in achieving compliance with law and facilitating the administration of justice, and indeed may avert litigation.
Upjohn Co. v. United States,
The district court cited
Edward Lowe Indus., Inc. v. Oil-Dri Corp. of America,
We conclude that the joint client doctrine and the community of interest doctrine apply to and protect legal advice and communications between the patent applicant or patentee and attorneys of its optionee/li-censee.
Accordingly, IT IS ORDERED THAT:
The writ of mandamus is granted. The communications for which discovery is sought are protected by the attorney-client privilege.
