MEMORANDUM AND ORDER

          WELSH, United States Magistrate Judge.

         Plaintiff, Greene, Tweed of Delaware, Inc. (" Green, Tweed" ), brought this action alleging that certain activities relating to the manufacture and sale of various products of defendant, DuPont Dow Elastomers, L.L.C. (" DuPont Dow" ), infringe United States Patent No. 5,461,107 (" the '107 patent" ). Plaintiff further contends that DuPont Dow's infringement was willful, and plaintiff therefore seeks, inter alia, increased damages and attorneys' fees.

          Presently before the Court is the Motion of Defendant, DuPont Dow, and Non-party, E.I. du Pont de Nemours and Company (hereinafter referred to as " the non-party" ), to Preclude Plaintiff from Naming Charles Stewart and Anestis Logothetis as Experts and to Preclude Plaintiff from Showing Confidential Information to Them as Fact Witnesses. Specifically, DuPont requests that the Court enter an Order (1) disqualifying former DuPont employees, Drs. Stewart and Logothetis, from serving as consultants or experts for plaintiff in this litigation, and (2) preventing these individuals from being provided confidential information of DuPont in their alternative capacities as fact witnesses. See DuPont's Mot. at 1.

         In support of the present motion, DuPont alleges that Drs. Stewart and Logothetis had access to confidential information during their previous employment with DuPont. Id. DuPont is concerned that if plaintiff uses Stewart and Logothetis as consultants or experts, they will inevitably disclose DuPont's confidential information to plaintiff. Id. at 1-2. In addition, DuPont is concerned that plaintiff will disclose confidential information to Stewart and Logothetis in their capacities as fact witnesses. Id. at 2.

         In its memorandum in opposition to DuPont's motion, plaintiff argues that " Greene, Tweed is entitled to any information bearing on its claim of infringement, confidential or not, and it is entitled to speak to any persons with knowledge thereon." See Pl.'s Mem. at 2. Plaintiff further argues that the Stipulation and Protective Order dated March 16, 2001 negotiated and agreed upon by the parties and approved by the Court sufficiently protects any legitimate interests in confidentiality of the parties. Id. In addition, plaintiff argues that " [n]ot a single shred of evidence has been presented to support any of [DuPont's] sweeping factual allegations" and that " [w]ithout providing hard evidence to support their claims ..., [DuPont] should not be awarded the extraordinary relief they seek." See Pl.'s Mem. at 4.

         I. DISQUALIFYING EXPERT WITNESSES

          Federal courts have the inherent power to disqualify expert witnesses in certain circumstances to protect the integrity of the adversary process and to promote public confidence in the legal system. Space Sys./ Loral v. Martin Marietta Corp., No. 95-20122, 1995 WL 686369, at *2 (N.D.Cal.1995) (citing Wang Labs., Inc. v. Toshiba Corp., 762 F.Supp. 1246, 1248 (E.D.Va.1991)). One situation where disqualification may be appropriate is when a party retains an expert witness who previously worked for an adversary and who acquired confidential information during the course of his employment. Space Sys./Loral, 1995 WL 686369, at *2; see Toshiba Corp., 762 F.Supp. at 1248.

          When determining whether to disqualify an expert based on a prior relationship with the adversary, a court must undertake the following two-step inquiry: (1) Did the adversary, in this case Dupont, have a confidential relationship with the expert?; and (2) Did the adversary disclose confidential or privileged information to the expert that is relevant to the current litigation? See Space Sys./Loral, 1995 WL 686369, at *2 (patent infringement suit where defendant moved to disqualify plaintiff's expert on the grounds that the expert previously worked for defendant); In re Orthopedic Bone Screw Prods. Liab. Litig., No. MDL 1014, 1995 WL 925673, at *3 (E.D.Pa. May 5, 1995) (denying defendant's motion to disqualify an expert despite defendant's allegations that it had retained the expert as a consultant and conveyed confidential information to him); Toshiba Corp., 762 F.Supp. at 1248 (patent infringement suit where plaintiff filed motion to disqualify expert claiming to have previously retained him).

          If the answers to both inquiries are affirmative, a court should disqualify the expert. In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at *3; Toshiba Corp., 762 F.Supp. at 1248. However, disqualification is likely inappropriate if either inquiry yields a negative response. Id.; see In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at *3. Thus, generally, disqualification " should not occur where a confidential relationship existed but no privileged information was communicated or alternatively, where no confidential relationship existed but privileged information was nonetheless disclosed." Id. (quoting Mayer v. Dell, 139 F.R.D. 1, 3 (D.D.C.1991) (citations omitted)).

          The party who seeks disqualification of an expert has the burden of showing the existence of confidentiality and its non-waiver. In re Orthopedic Bone Screw Prods. Liab. Litig, 1995 WL 925673, at *3; United States ex rel. Cherry Hill Convalescent Ctr., Inc. v. Healthcare Rehab Sys., Inc., 994 F.Supp. 244, 249 (D.N.J.1997); English Feedlot, Inc. v. Norden Labs., Inc., 833 F.Supp. 1498, 1501-02 (D.Colo.1993). Furthermore, the party requesting disqualification may not meet its burden with " mere conclusory or ipse dixit assertions." In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at *6 (citing Nikkal Indus., Ltd. v. Salton, Inc., 689 F.Supp. 187, 191 (S.D.N.Y.1988)).

         In the present case, DuPont clearly had a confidential relationship with both Stewart and Logothetis at the time of their previous employment, and plaintiff does not specifically deny this in its opposition to DuPont's motion. Both individuals were employed by DuPont as research scientists, and both signed employment and termination agreements that included confidentiality clauses (copies of which are attached to DuPont's Motion as Exhibit " A" ). Therefore, DuPont has satisfied the first part of the aforementioned two-prong test, and the remaining issue is whether confidential information was disclosed to these individuals " that is relevant to the current litigation" and that would warrant a disqualification of either or both of them as experts for plaintiff. See Space Sys./Loral, 1995 WL 686369, at *2; see also In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at *3; Toshiba Corp., 762 F.Supp. at 1248.

         In Viskase Corp. v. W.R. Grace and Co.-Conn., No. 90-7515, 1992 WL 13679, at *1 (N.D.Ill. Jan. 24, 1992), a patent infringement case, the plaintiff corporation sought to disqualify the defendant's proposed expert on the grounds that the individual was previously employed by the plaintiff's predecessor corporation. As in the present case, the proposed expert had signed an employment agreement requiring confidentiality with the predecessor corporation of the party seeking disqualification. Id. at *6 n. 2.

         The Court in Viskase found that the plaintiff had failed to demonstrate that the proposed expert had " direct involvement in the licensing of products containing the resins at issue in [the] lawsuit." Id. at *2. The Viskase Court further concluded that " there [was] not a substantial relationship between the confidential information [the proposed expert] would have acquired while employed by [the predecessor corporation] and the matters to which he would be expected to testify in this case." Id. (emphasis added). Accordingly, the Court in Viskase denied the motion to disqualify the proposed expert. Id.

         In Space Systems/Loral, 1995 WL 686369, at *1, the plaintiff alleged the infringement of two of its patents covering " attitude control" technology which enabled satellites to maintain a constant orientation towards the earth. The defendant corporation sought to disqualify two individuals who had previously been employed by the defendant from being designated as experts for the plaintiff, Space Systems/Loral (" SSL" ). The proposed experts had signed confidentiality agreements with the defendant corporation. Id. at *1, *3.

          The Court granted the defendant's motion to disqualify one of the proposed experts on the basis that the proposed expert " had significant involvement in designing the attitude control systems" for the alleged infringing products in that litigation, and the witness " was privy to substantial confidential information from [the defendant] that [was] relevant to the issues in [the] case." Id. at *2-3. With regard to the second proposed expert in Space Systems/Loral, the defendant corporation alleged that the proposed expert possessed " crucial" knowledge because he was involved in the development of attitude control systems which were " operationally similar" to the infringing products and " which evolved into the system used in the [infringing products]." Id. However, the Court noted that this second proposed expert " possess[ed] no confidential information concerning ... the specific technology at issue in this lawsuit." Id. (emphasis added). Therefore, with respect to that individual, the Court denied the motion to disqualify plaintiff's expert. Id.

         In the present case, as explained above, DuPont has the burden of showing the existence of confidentiality and its non-waiver. In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at 3; United States ex rel. Cherry Hill Convalescent Ctr., Inc., 994 F.Supp. at 249; English Feedlot, Inc., 833 F.Supp. at 1501-02. However, DuPont has failed to satisfy its burden of demonstrating that Drs. Logothetis or Stewart were privy to " confidential information concerning ... the specific technology at issue in this lawsuit." See Space Sys./Loral, 1995 WL 686369, at *3; see also Viskase Corp., 1992 WL 13679, at *2; In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at *7 (" record is void of any evidence that confidential information was disclosed ..." ).

         As explained by the Court in Space Systems/Loral, asserting that the proposed experts were involved in the development of technology which was " operationally similar" to the infringing products or " which evolved into the [technology] used in the [infringing products]" is not enough. See Space Sys./Loral, 1995 WL 686369, at *2-3. Nor can DuPont satisfy its burden by making conclusory assertions that the proposed experts were " privy to substantial confidential information related and unrelated to this litigation." See, e.g., DuPont's Mot. at 9. For example, DuPont's conclusory assertions that certain information is " not publicly available," without supporting evidence, is not enough to satisfy the burden of showing confidentiality and its non-waiver. See In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at 3; United States ex rel. Cherry Hill Convalescent Ctr., Inc., 994 F.Supp. at 249; English Feedlot, Inc., 833 F.Supp. at 1501-02. Of course, as plaintiff points out, see Pl.'s Letter Brief dated 4/6/01, at 2, the fact that an individual may have had access to public information about a product cannot be a basis to disqualify him from being an expert.

          With respect to Dr. Logothetis, although documents submitted by DuPont indicate that he assisted in the development of improved polymerization, the documents do not show that he was privy to confidential information relevant to the alleged infringing products in this case. See Viskase Corp., 1992 WL 13679, at *2. Furthermore, as plaintiff correctly points out, see Pl.'s Letter Brief dated 4/6/01, at 2, the fact that Dr. Logothetis' name appears on some " Distribution" lists, along with approximately one hundred other names, also does not prove that he was privy to confidential information substantially related to the alleged infringing products. See, e.g., In re Orthopedic Bone Screw Prods. Liab. Litig., 1995 WL 925673, at *7 (affidavit stating that " the parties discussed confidential information at the meeting, including ‘ the scope of the products liability litigation pending against [the defendant], including this litigation’ ... [did] not provide the court with sufficient evidence that confidential information was discussed." ). DuPont has failed to present evidence demonstrating that any information to which Dr. Logothetis was privy was kept confidential at the time it was given or that confidentiality has since been maintained and not waived. See id. at *3 (party seeking disqualification of expert has burden of showing existence of confidentiality and its non-waiver); United States ex rel. Cherry Hill Convalescent Ctr., Inc., 994 F.Supp. at 249 (same); English Feedlot, 833 F.Supp. at 1501-02 (same).

          With regard to Dr. Stewart, DuPont has submitted for in camera review Document Nos. 9 and 12 identified in DuPont Dow's Second Privilege Log in support of the claim that Dr. Stewart was privy to attorney-client privileged communications. See DuPont's Letter Brief dated 4/5/01, at 2. In opposition to this claim of privilege, plaintiff responds that " [b]y relying on an opinion of counsel concerning [the] alleged invalidity of the '107 patent [in DuPont Dow's affirmative defenses to plaintiff's charge of willful infringement], DuPont Dow has waived its privilege with regard to the subject matter of that opinion, i.e., the invalidity of the '107 patent." See Pl.'s Letter Brief dated 4/6/01, at 3. Plaintiff further points out that " this very issue is argued in [plaintiff's] motion to compel documents." Id. at 4.

         By Memorandum and Order dated May 1, 2001, this Court granted in part and denied in part plaintiff's aforementioned Motion to Compel Documents Identified in Defendant DuPont Dow's Privilege Log, which included a request for Document Nos. 9 and 12 identified in DuPont Dow's Second Privilege Log. As explained in the May 1st Memorandum and Order, " DuPont Dow has waived the [attorney-client] privilege ... with respect to the issue of validity of the '107 patent." See Mem. and Order dated 5/1/01, at 7 (citing Saint-Gobain/Norton Indus. Ceramics Corp. v. General Elec. Co., 884 F.Supp. 31, 34 (D.Mass.1995)); see also Applied Telematics, Inc. v. Sprint Corp., No. 94-4603, 1995 WL 567436, at *3 (E.D.Pa. Sept. 21, 1995); Mushroom Assoc. v. Monterey Mushrooms, Inc., No. 91-1092, 1992 WL 442892, at *3 (N.D.Cal. May 19, 1992).

         According to DuPont Dow's own description of Document No. 12 in the Second Privilege Log, this document " reflects legal advice regarding [the] invalidity of [the] '107 patent based upon prior art" (emphasis added). Furthermore, Document No. 9 appears to be a memorandum provided in response to inquiries made in Document No. 12 related to the invalidity of the '107 patent. See DuPont's Letter Brief dated 4/5/01, at 2. Moreover, in DuPont's April 5, 2001 letter brief in support of the present motion, counsel acknowledges that " [Document Nos. 9 and 12] reflect assembling information concerning invalidity for anticipation." See DuPont's Letter Brief dated 4/5/01, at 2 (emphasis added).

         In any event, this Court has previously determined that DuPont Dow waived the attorney-client privilege with respect to the information reflected in Document Nos. 9 and 12, since these two documents are relevant to the issue of invalidity of the '107 patent. See Mem. and Order dated 5/1/01, at 10-11. Accordingly, DuPont has failed to demonstrate that while Dr. Stewart was employed by DuPont, he was privy to any communications which are now privileged and not waived.

          Since DuPont has failed to meet its burden of demonstrating that Dr. Logothetis or Dr. Stewart were privy to confidential information while employed at DuPont which was substantially related to the alleged infringing products in this case, DuPont's motion to preclude plaintiff from naming these gentlemen as experts is denied. See Viskase Corp., 1992 WL 13679, at *2; see also Space Sys./Loral, 1995 WL 686369, at *2-3. Of course, any information designated as " Confidential Information" by any party or non-party disclosing such information during discovery is subject to the March 16, 2001 Stipulation and Protective Order entered in this case which provides, inter alia, that any such information shall be used " solely for the preparation, trial, and appeal of this lawsuit; settlement discussions and negotiations pertaining to this lawsuit; or any form of alternative dispute resolution of this lawsuit; and for no other purpose of publication whatsoever, whether directly or indirectly." See Stip. and Prot. Order dated 3/16/01, ¶ 2.

         II. STEWART AND LOGOTHETIS AS FACT WITNESSES

          DuPont " do[es] not dispute that trade secrets are relevant to this case," and it acknowledges that several former DuPont employees, including Drs. Stewart and Logothetis, " may have factual knowledge relevant to the issues in this case, and [DuPont Dow] expect[s] to call them as fact witnesses as well." See DuPont's Mot. at 14. However, although it does not seek to preclude plaintiff from calling Drs. Stewart and Logothetis as fact witnesses, DuPont is " concerned ... that [plaintiff] wishes to show documents containing [DuPont] confidential information, and to discuss such information with Stewart, Logothetis, and other ex-employees without anyone else present." See DuPont's Mot. at 14. On these bases, DuPont's motion requests the following specific relief: either (1) a representative from DuPont be present during plaintiff's discussions with Drs. Stewart and Logothetis, and be given an opportunity to object, or (2) that Drs. Stewart and Logothetis be appointed their own, independent counsel, who would not represent either party to this suit. Id. at 15.

         DuPont fails to cite any applicable caselaw where a court granted the specific relief requested by DuPont in the present case with respect to a fact witness. Indeed, at the April 4, 2001 oral argument on the present motion, counsel for DuPont acknowledged that it knew of no such caselaw where the specific relief requested by DuPont was granted in this context.

         In Wang Laboratories, Inc. v. CFR Associates, Inc., 125 F.R.D. 10 (D.Mass.1989), the plaintiff filed a motion for a protective order to prohibit the defendant in that case from contacting a proposed witness who was a former employee of the plaintiff corporation and who was also subject to a confidentiality clause in his employment contract. Although the Court in Wang Laboratories disqualified the proposed expert in that case, the Court found that " [b]ecause of his role in the development of the software for the computer system at issue, [the witness] may be an appropriate fact witness." Id. at 13. The Court held that the defendant " may show [the witness] and discuss with him any documents which he authored or which the document reveals he received." Id. at 14.

         Similarly, in the present case, the March 16, 2001 Stipulation and Protective Order which was negotiated and agreed upon by the parties and approved by the Court, states:

Witnesses or potential witnesses may be shown any Confidential Information that that person had lawfully received prior to and apart from this lawsuit or which appears on its face or from other documents, testimony, or information to have been authored by that witness, received by that witness, or communicated to that witness.

Stip. and Prot. Order dated 3/16/01, ¶ 6(e). Furthermore, as discussed above, pursuant to the Stipulation and Protective Order, any exchange of confidential information during discovery in this litigation " shall be used by every party or non-party receiving such information ... solely for the preparation, trial, and appeal of this lawsuit; settlement discussions and negotiations pertaining to this lawsuit; or any form of alternative dispute resolution of this lawsuit; and for no other purpose or publication whatsoever, whether directly or indirectly." Id. ¶ 2. Accordingly, in light of the lack of caselaw cited as authority in support of the specific relief requested by DuPont in the present motion with respect to Drs. Stewart and Logothetis as fact witnesses, and consistent with the March 16, 2001 Stipulation and Order entered in this case, plaintiff may question Drs. Stewart and Logothetis about the documents which they authored or received, and DuPont's motion is denied.

         An implementing Order follows.

          ORDER

         AND NOW, this 8th day of May, 2001, upon consideration of the Motion of Defendant, DuPont Dow Elastomers, L.L.C. (" DuPont Dow" ), and non-party, E.I. du Pont de Nemours and Company, to Preclude Plaintiff from Naming Charles Stewart and Anestis Logothetis as Experts and to Preclude Plaintiff from Showing Confidential Information to Them as Fact Witnesses, for the reasons given in the accompanying Memorandum, it is hereby ORDERED that the motion is DENIED.
