After losing their jobs at the Weyerhaeuser Company’s Valliant, Oklahoma containerboard plant as part of a reduction in force, the plaintiffs filed this wrongful termination action against Weyerhaeuser, alleging violations of the Age Discrimination in Employment Act (ADEA), 29 U.S.C. §§ 621-34, and state law. In pretrial briefing, the plaintiffs requested that the court apply the pattern-or-practice framework adopted by the Supreme Court in
International Brotherhood of Teamsters v. United States,
The district court denied Weyerhaeuser’s motion, reasoning that this court’s decision in
Thiessen v. General Electric Capital Corp.,
Weyerhaeuser now re-urges its argument that the pattern or practice framework should not be applied. It further contends that our decision in Thiessen did not reach that question.
We are not persuaded.

I. BACKGROUND
In 2002, Weyerhaeuser’s Valliant, Oklahoma plant implemented a reduction in force. As a result, sixteen of the plaintiffs were discharged. The seventeenth plaintiff, Larry Thompson, was discharged in 2003. Each of the plaintiffs was over forty years of age at the time of discharge.
The plaintiffs then filed this wrongful discharge action in the Eastern District of Oklahoma, alleging violations of the ADEA and state law. The district court granted summary judgment to the defendants on the grounds that the plaintiffs had signed a waiver of their right to file an ADEA claim in order to obtain a severance package. However, in a prior appeal, this court held that the waivers were not valid, reversed the grant of summary judgment, and remanded the case for further proceedings.
See Kruchowski v. Weyerhaeuser Co.,
After remand, as we have noted, the district court denied Weyerhaeuser’s request to strike the pattern-or-practice theory of discrimination advanced by the plaintiffs but certified the ruling for interlocutory appeal.
II. DISCUSSION
Weyerhaeuser now argues that, in contrast to Title VII, the ADEA does not
*1127
authorize a court to apply the pattern-or-practice framework for assessing claims of age discrimination. Weyerhaeuser acknowledges that this court’s decisions in
Thiessen
and
EEOC v. Sandia Corp.,
A. The pattern-or-practice framework has been widely applied to ADEA cases.
The federal statutes barring discrimination in employment contain only a brief reference to the pattern-or-practice framework at issue here. A section of Title VII authorizes the Attorney General to file a civil action against “any person or group of persons” whom he or she has reasonable cause to believe “is engaged in a pattern or practice of resistance to the fall enjoyment of any of the rights secured by this sub-chapter, and that the pattern or practice is of such a nature and is intended to deny the full exercise of the rights herein described.” 42 U.S.C. § 2000e-6(a) (emphasis added).
Unlike Title VII, the ADEA contains no express reference to pattern-or-practice claims. The ADEA does adopt the opt-in class mechanism of the Fan- Labor Standards Act, which authorizes class actions when the complaining employees are “similarly-situated.”
See
29 U.S.C. § 626(b) (providing that the provisions of the ADEA “shall be enforced in accordance with the powers, remedies, and procedures provided in [specified sections of the Fair Labor Standards Act,]” including the Fair Labor Standards Act provision regarding class actions, 29 U.S.C. § 216(b)). However, that class action statute does not use the term “pattern-or-practice.”
See generally Thiessen,
In the absence of specific statutory provisions, the details of the pattern-or-practice framework have developed in Supreme Court decisions in which the plaintiffs alleged that employers had violated Title VII by engaging in “a pattern of discriminatory decisionmaking.”
See Cooper v. Fed. Reserve Bank of Richmond,
In a pattern-or-practice case, the Court concluded, the trier of fact should first determine whether the allegedly discriminatory pattern or practice actually existed. In contrast to cases alleging solely individual discrimination, the initial focus of a pattern-or-practice case is upon the defendant employer’s “standard operating procedure.”
Teamsters,
On the other hand, if the plaintiff proves that a discriminatory pattern or practice existed, the court may award prospective equitable relief.
See id.
at 1106. The
Teamsters
Court explained that “[s]uch relief might take the form of an injunctive order against continuation of the discriminatory practice, an order that the employer keep records of its future employment decisions and file periodic reports with the court, or any other order necessary to ensure the full enjoyment of the rights protected by Title VII.”
After this initial phase of a pattern-or-practice case, the inquiry shifts. The fact-finder must proceed to determine whether “any particular employment decision, during the period in which the discriminatory policy was in force, was made in pursuit of that [pattern or practice].”

This circuit has applied the pattern-or-practice framework in ADEA actions. For example, in
Thiessen,
the plaintiffs had alleged that their employer had adopted a “blocker policy” under which management “began referring to the older [executive] employees as ‘blockers,’ because in their view these employees were ‘blocking’ the advancement of younger, newly recruited employees,” and then taking adverse employment actions against the older employees.
In ruling that the district court had erred in decertifying the class, we explained that the plaintiffs were asserting “a pattern-or-practice claim modeled on
[Teamsters]
” and that the district court had failed to recognize that the plaintiffs’ trial plan “was consistent with the framework outlined in
Teamsters
for pattern-or-practice claims.”
Thiessen,
That holding is echoed by several of our sister circuits.
See Hipp v. Liberty Nat’l Life Ins. Co.,
Scholarly commentary is in accord. See 8 Lex K. Larson, Employment Discrimination § 137.02, at 137-16 (2d ed. 2008) (“Although there is no ADEA counterpart to the ‘pattern or practice’ provision of Title VII, both the government and private classes of plaintiffs have been permitted to bring what amounts to age-based pattern- or practice suits.”); 2 Howard C. Eglit, Age Discrimination § 7:40, at 7-387 to 7-388. (2d ed.1994) (stating that “generally, the pattern or practice method of proof is almost exclusively used in class actions” and that “[generally, ADEA courts have looked to cases decided under Title VII ... for guidance and they have embraced the pattern or practice precedents developed in the Title VII context”).
B. Thiessen is controlling.
Weyerhaeuser insists that
Thiessen’s
statements that the pattern-or-practice framework applies to ADEA claims are merely dicta that we need not follow here. It invokes the principle that “a panel of this [c]ourt is bound by a holding of a prior panel of this [c]ourt but is not bound by a prior panel’s dicta.”
Bates v. Dep’t of Corr.,
We disagree. Dicta are “ ‘statements and comments in an opinion concerning some rule of law or legal proposition not necessarily involved nor essential to determination of the case in hand.’”
Rohrbaugh v. Celotex Corp.,
In particular, that determination was “necessarily involved” and “essential to the determination of the case in hand.” Rohr *1130 baugh, 53 F.3d. at 1184 (quoting Black’s Law Dictionary 454 (6th ed.1990)). The Thiessen panel concluded that the district court’s decertification of the plaintiff class constituted an abuse of discretion because the plaintiffs were proceeding under a pattern or practice framework. “Necessarily involved” and “essential to th[at] determination” is the associated conclusion that the pattern-or-practice framework is proper in ADEA cases. Id.
Moreover, our review of the parties’ briefs in Thiessen indicates that the application of the pattern-or-practice framework to ADEA claims was specifically addressed there. The Thiessen plaintiffs urged the application of the Teamsters pattern-or-practice framework, see Aplt’s Br. at 57, Reply Br. at 33, Thiessen (No. 98-3203), while the defendant employer argued that the application of that framework would violate its due process rights, see Aple’s Br. at 33-34, Thiessen (No. 98-3203) (contending that “the bifurcated trial scheme contemplated by ... Teamsters is constitutionally questionable in the context of a jury trial”).
Weyerhaeuser observes that neither Thiessen nor Sandia Corp. addressed many of the particular challenges to the application of the pattern-or-practice framework that it seeks to advance here. For example, in its opening brief in this case, Weyerhaeuser invokes parts of the ADEA’s legislative history, see Aplt’s Br. at 15-22, and there is no discussion of that history in our two earlier cases.
That argument is also unavailing. The fact that our earlier decisions do not address particular arguments that Weyerhaeuser now advances does not transform the legal conclusions that we reached in those cases from holdings into dicta. The gist of Weyerhaeuser’s arguments is that, in applying the pattern-or-practice framework to ADEA claims,
Thiessen
and
Sandia Corp.
were wrongly decided. Absent an intervening Supreme Court or en banc decision justifying such action, we lack the power to overrule our own precedent.
United States v. Hernandez-Rodriguez,
C. The Supreme Court’s Decision in Gross v. FBL Financial Services, Inc. does not overrule Thiessen.
In a supplemental letter to this court, Weyerhaeuser contends that the Supreme Court’s recent decision in
Gross v. FBL Financial Services, Inc.,
— U.S. -,
The Court contrasted that burden to the lesser one imposed on plaintiffs in Title VII cases.
See id.
at 2349 (explaining that “Congress has since amended Title VII by
*1131
explicitly authorizing discrimination claims in which an improper consideration was a motivating factor”) (internal citation omitted). It also noted that, in Title VII “mixed motive” cases, once a “plaintiff ... proves that [the plaintiffs membership in a protected class] played a motivating part in an employment decision, the defendant may avoid a finding of liability only by proving by a preponderance of the evidence that it would have made the same decision even if it had not taken [that factor] into account.”
Id.
(quoting
Price Waterhouse v. Hopkins,
We are not persuaded by Weyerhaeuser’s argument. Gross does not involve the pattern-or-practice procedure at issue here. Moreover, the Court relied on the fact that Congress had amended Title VII to expressly adopt a “motivating factor” standard for discrimination rather than a “but for” inquiry. Here, Weyerhaeuser cannot point to an analogous difference in the language of Title VII and the ADEA that establishes that the pattern-or-practice framework is proper under one anti-discrimination statute but not the other.
As we have noted, Title VII does contain a brief reference to pattern-or-practice claims filed by the Attorney General,
see
42 U.S.C. § 2000e-6(a), while the ADEA contains no similar provision. However, the pattern-or-practice burden shifting framework at issue here is mentioned in neither statute. Instead, that framework has been established by the courts.
See Teamsters,
III. CONCLUSION
The district court did not err in deciding to apply the pattern-or-practice framework to the plaintiffs’ ADEA claim. We therefore AFFIRM its decision denying Weyerhaeuser’s motion to strike and REMAND the case to the district court for further proceedings consistent with this opinion.
