ON PETITION FOR WRIT OF MANDAMUS
ORDER
This petition arises out of an order of the United States District Court for the Northern District of Illinois compelling MSTG, Inc. (“MSTG”) to produce documents related to license negotiation discussions between MSTG and six other companies, including previous defendants in this suit. We are asked to decide first, as a matter of first impression, whether such communications related to reasonable royalties and damages are protected from discovery based on a settlement negotiation privilege, and second, whether on the facts of this case the district court clearly abused its discretion by ordering their production. Because we conclude that the communications are not privileged, and that the district court did not clearly abuse its discretion, we deny the petition for writ of mandamus.
Background
In 2008, MSTG sued AT & T Mobility, LLC (“AT & T”) and other cell phone service providers and mobile device manufacturers claiming infringement of U.S. Patent Nos. 5,920,551, 6,198,936, and 6,438,113 (collectively, the “patents-in-suit”) covering third-generation (“3G”) mobile telecommunications technologies. In 2009, MSTG initiated another lawsuit against other cell phone service providers and mobile device manufactures, also alleging infringement of the patents-in-suit. MSTG eventually settled with all defendants other than AT & T. As part of the settlement agreements, most defendants were granted licenses under the patents-in-suit as well as under other patents owned by MSTG. One defendant entered into an agreement giving it an option to license the patents at a predetermined rate. Additionally, during this time period, MSTG licensed the patents-in-suit to a technology consortium, providing the consortium the right to grant a sublicense to its more than 50 members, a few of which were defendants in the pending litigation.
One of the issues in the litigation was the amount of a reasonable royalty if AT & T were found to infringe the patents-in-suit. License agreements can be pertinent to the calculation of a reasonable royalty. During discovery and in response to AT
&
T’s document requests, MSTG produced six license agreements and the option agreement (collectively, the “settlement agreements”). AT & T then sought further discovery into the negotiations of the settlement agreements on the theory that those negotiations too could be pertinent to a reasonable royalty. MSTG objected on the ground that the negotiations were irrelevant to the reasonable royalty calculation. AT & T moved to compel the production of all “documents reflecting
*1330
communications between MSTG or its attorneys, on the one hand, and either licensees or parties threatened with infringement by MSTG, on the other.” Resp’t’s App. 270. In a January 20, 2011, order, a magistrate judge denied AT & T’s motion to compel, finding that “AT & T has not carried its burden of showing why the settlement negotiations are relevant and discoverable under the standards of Rule 26.”
MSTG, Inc. v. AT & T Mobility LLC (“Initial Order”),
No. 08-C-7411, slip op. at 28,
On January 10, 2011, after AT & T had submitted its motion to compel, MSTG served an expert report by Frank Bernatowicz on the issue of damages. This report was not submitted to the magistrate judge before he issued his January 20, 2011, order. In this report, Mr. Bernatowicz offered an opinion regarding a reasonable royalty for AT & T’s alleged infringement of the patents-in-suit by “analyz[ing] royalty rates from potentially comparable licenses, industry survey results, licensing policies of the 3GPP, and other published licensing rates for similar technology.” Resp’t’s App. 144-45. Although the expert had “reviewed the[] six agreements and taken them into consideration in [his] reasonable royalty analysis,” he did not find the royalty rates in those agreements to “be comparable to the hypothetical negotiation between MSTG and AT & T.” Resp’t’s App. 138. This was so because most of the royalty agreements were “litigation related compromises,” id., and because they covered additional patents beyond the patents-in-suit. There was no showing that the expert had access to the negotiation documents, though he relied on deposition testimony of an MSTG executive that the agreements reflected litigation-related compromises.
AT
&
T sought reconsideration of the January 20, 2011, order on the grounds that the expert’s discussion of the license agreements in his report constituted newly discovered evidence supporting discovery of the settlement negotiations. Granting the motion, the magistrate judge found that the negotiation documents “might contain information showing that the grounds Bernatowicz relied on to reach his conclusion are erroneous.”
MSTG, Inc. v. AT & T Mobility LLC (“Reconsideration Order”),
No. 08-C-7411, slip op. at 4,
The district court denied MSTG’s objections and adopted the order. MSTG, Inc. v. AT & T Mobility LLC (“Final Discovery Order”), No. 08-C-7411, slip op. at 2 (N.D.Ill. June 27, 2011). In doing so, the district court agreed with the analysis of the magistrate judge. Additionally, it found that because MSTG’s expert relied on the testimony of MSTG’s executive regarding MSTG’s “business reasons” for entering into the license agreements, it would be unfair for MSTG to “then shield those reasons from further examination.” Id. On July 7, 2011, MSTG moved the district court to stay its June 27, 2011, order pending MSTG’s petition for writ of mandamus. The district court denied MSTG’s motion.
*1331
MSTG petitioned this court for a writ of mandamus to vacate the June 27, 2011, order and simultaneously moved for a stay of the discovery order pending our review of the petition. On July 29, 2011, we temporarily stayed the district court’s discovery order pending our review. We have jurisdiction under 28 U.S.C. § 1295.

Discussion
I
“As to discovery matters, we have held that Federal Circuit law applies when deciding whether particular written or other materials are discoverable in a patent case, if those materials relate to an issue of substantive patent law.”
Advanced Cardiovascular Sys., Inc. v. Medtronic, Inc.,
II
Pursuant to the All Writs Act, 28 U.S.C. § 1651(a), this court has the authority to issue a writ of mandamus as “necessary or appropriate in aid of’ our jurisdiction.
Miss. Chem. Corp. v. Swift Agric. Chems. Corp.,
It is generally inappropriate to review discovery orders by mandamus. However, mandamus may be appropriate where a discovery order “raises a novel and important question of power to compel discovery, or ... reflects substantial uncertainty and confusion in the district courts.” 16 Charles Alan Wright, Arthur R. Miller & Edward H. Cooper,
Federal Practice and Procedure: Jurisdiction and Related Matters
§ 3935.3 (2d ed.1996) (citing
Schlagenhauf v. Holder,
*1332
Thus, “mandamus may properly be used as a means of immediate appellate review of orders compelling the production of documents claimed to be protected by privilege or other interests in confidentiality.”
Bogosian v. Gulf Oil Corp.,
Ill
There are two primary issues. First, MSTG argues that the license negotiations between it and its other licensees are protected by a settlement negotiation privilege. Second, MSTG argues that here, where the fully-integrated settlement agreements are already part of the record, the district court clearly abused its discretion by ordering the production of the underlying settlement negotiations.
A.
MSTG urges us to invoke Rule 501 of the Federal Rules of Evidence to fashion a new privilege in patent cases that would prevent discovery of litigation settlement negotiations related to reasonable royalties and damages. In this respect, MSTG urges us to adopt the reasoning of the United States Court of Appeals for the Sixth Circuit in
Goodyear Tire & Rubber Co. v. Chiles Power Supply, Inc.,
The scope of discovery is governed by Rule 26(b)(1) of the Federal Rules of Civil Procedure, which provides in relevant part:
Parties may obtain discovery regarding any non-privileged matter that is relevant to any party’s claim or defense.... Relevant information need not be admissible at the trial if the discovery appears reasonably calculated to lead to the discovery of admissible evidence.
Discovery of privileged material is not permissible. Rule 501 of the Federal Rules of Evidence authorizes federal courts to define new privileges by interpreting “[t]he
*1333
common law ... in the light of reason and experience.” “The Rule thus did not freeze the law governing the privileges of witnesses in federal trials at a particular point in our history, but rather directed federal courts to ‘continue the evolutionary development of testimonial privileges.’ ”
Jaffee v. Redmond,
The Supreme Court has identified several factors to be considered in assessing the propriety of defining a new privilege under Rule 501. These factors do not support recognition of a settlement privilege here.
First, “the policy decisions of the States bear on the question whether federal courts should recognize a new privilege or amend the coverage of an existing one.”
Jaffee,
Second, in determining whether a new privilege should be adopted, courts look to whether Congress had considered that or related questions.
See Univ. of Pa. v. EEOC,
The rule is clear by its text and history that it covers not only settlements and negotiations between the parties to the lawsuit, but also settlements and negotiations involving a third party. The advisory committee proposing the rule specifically stated:
While the rule is ordinarily phrased in terms of offers of compromise, it is apparent that a similar attitude must be taken with respect to completed compromises when offered against a party thereto. This latter situation will not, of course, ordinarily occur except when a party to the present litigation has compromised with a third person.
Fed.R.Evid. 408 advisory committee’s note (1972 Proposed Rules). This understanding has been echoed by both courts,
see, e.g., McInnis v. A.M.F., Inc.,
In enacting Rule 408, Congress did not take the additional step of protecting settlement negotiations from discovery. Adopting a settlement privilege would require us to go further than Congress thought necessary to promote the public good of settlement, or in other words, to strike the balance differently from the one Congress has already adopted. This also suggests that it is not appropriate to create a new privilege for settlement discussions.
This situation is similar to that in
University of Pennsylvania,
Third, in determining whether new privileges should be recognized, the Supreme Court has been influenced by the list of evidentiary privileges recommended by the Advisory Committee of the Judicial Conference in its proposed Federal Rules of Evidence.
See Jaffee,
Fourth, “[t]he Supreme Court requires that a party seeking judicial recognition of a new evidentiary privilege under Rule 501 demonstrate ... that the proposed privilege will effectively advance a public good.”
In re Sealed Case,
Fifth, any settlement privilege would necessarily have numerous exceptions. Rule 408 itself contemplates a host of scenarios under which documents related to settlement negotiations would be admissible for purposes other than “proving] or disproving] the validity or amount of a disputed claim or [] impeaching] by a prior inconsistent statement or a contradiction.” For example, settlement negotiation evidence would be admissible where the settlement itself or its interpretation is at issue or where evidence of the ingredients of the settlement might be relevant to an issue of double recovery.
See, e.g., Portugues-Santana v. Rekomdiv Int’l,
Finally, to the extent we need to protect the sanctity of settlement discussions and promote the compromise and settlement of dispute, there are other effective methods to limit the scope of discovery to achieve those ends — primarily Rule 26 of the Federal Rules of Civil Procedure. In general, the Federal Rules of Civil Procedure promote a “broad and liberal” policy of discovery “for the parties to obtain the fullest possible knowledge of the issues and facts before trial.”
Hickman v. Taylor,
The Supreme Court has instructed us that the federal courts “should not hesitate to exercise appropriate control over the discovery process” to “prevent abuse.”
Herbert v. Lando,
Similarly, the Advisory Committee’s note to Rule 26 recognizes that the discovery rules “confer[] broad powers on the courts to regulate or prevent discovery even though the materials sought are within the scope of 26(b).” Fed.R.Civ.P. 26 advisory committee’s note (1970 Amendment Subdivision (b)). While typically settlement negotiations that are admissible under Federal Rule of Evidence 408
4
or disclosed to a party’s expert
5
would be
*1337
discoverable, the district court has discretion to limit discovery of material that is not itself admissible and that was not utilized by the opposing party to protect settlement confidentiality. Even as to such admissible or disclosed material, some protections may be appropriate. Significantly, citing the example of a tax return, the Advisory Committee proposing Rule 26 acknowledged that discovery could be limited where competing confidentiality interests are at stake.
Id.
The Advisory Committee recognized that although a party’s tax return is generally held not privileged, an individual’s “interests in privacy may call for a measure of extra protection.”
Id.
(citing
Wiesenberger v. W.E. Hutton & Go.,
We note that other courts have imposed heightened standards for discovery in order to protect confidential settlement discussions. In the context of confidential mediation communications, the Second Circuit has held that because “confidentiality in [mediation] proceedings promotes the free flow of information that may result in the settlement of a dispute,” a party seeking discovery of confidential communications must make a heightened showing “demonstrating] (1) a special need for the confidential material, (2) resulting unfairness from a lack of discovery, and (3) that the need for the' evidence outweighs the interest in maintaining confidentiality.”
In re Teligent, Inc.,
*1338
Therefore, in light of reason and experience, we hold that settlement negotiations related to reasonable royalties and damage calculations are not protected by a settlement negotiation privilege.
See In re Gen. Motors,
B.
Our cases appropriately recognize that settlement agreements can be pertinent to the issue of reasonable royalties.
See generally ResQNet.com, Inc. v. Lansa, Inc.,
The magistrate judge first denied discovery of the settlement negotiations because the settlement agreements had already been produced and AT & T had not shown a need for discovery as to the underlying settlement negotiations. After MSTG’s expert offered his opinion regarding a reasonable royalty for AT & T’s alleged infringement, the magistrate judge reconsidered and ordered production of the negotiation documents “because they might contain information showing that the grounds [MSTG’s expert] relied on to reach his conclusion are erroneous.” Reconsideration Order, slip op. at 4. The district court agreed, and ordered production to permit AT & T “the ability to test the accuracy of [the expert’s] opinions and assumption.” Final Discovery Order, slip op. at 2.
While MSTG argues that its expert relied only on information within the four corners of the settlement agreements,
see Reconsideration Order,
slip op. at 3, AT
&
T points to specific opinions offered by the expert that go beyond the four corners of the agreements,
see id.
at 4. For example, the expert concluded that the rates in the settlement agreements were “discounted by at least 75%” because they were entered before any substantive litigation rulings such as claim construction or summary judgment. Resp’t’s App. 139. On this issue the agreements themselves did not support the opinion. Rather, the expert cited an MSTG executive as to MSTG’s supposed reasons for entering into the agreements as well as other data. As a matter of fairness MSTG cannot at one and the same time have its expert rely on information about the settlement negotiations and deny discovery as to those same negotiations.

Accordingly,
It Is Ordered That:
(1) The petition for a writ of mandamus is denied.
(2) All pending motions are moot.
Notes

. The Federal Rules of Evidence were amended, effective December 1, 2011. These *1334 amendments, however, were “intended to be stylistic only. There [was] no intent to change any result in any ruling on evidence admissibility.” Fed.R.Evid. 408 advisory committee’s note to 2011 amendments. Thus, we cite here to the amended version of the rules.
