OPINION
I. Introduction
In this сonsolidated interlocutory appeal and mandamus proceeding, Relator and Appellant Gerald W. Haddock seeks relief from the trial court’s order staying arbitration proceedings that he initiated against Appellees and Real Parties in Interest William F. Quinn, Paul E. Rowsey, III, John Goff, Terry N. Worrell, Crescent Real Estate Equities Company (“CEI”), Crescent Real Estate Equities Limited Partnership (“CREELP”), and Crescent Real Estate Equities, Limited (“CREE”).
Haddock raises three issues. In his first issue, Haddock argues that the trial court improperly assumed jurisdiction because the parties contracted to have all issues — including questions of arbitrability — decided by arbitration. Second, Haddock contends that even if the trial court had jurisdiction to decide some issues of arbitrability, the main issue in this case— whether he repudiated or waived arbitration — should be decided by an arbitrator. Third, Haddock argues that the trial court erred and abused its discretion by concluding that he repudiated or waived arbitration by engaging in prior litigation that was inconsistent with arbitration.
Real Parties in Interest contend that the issue of repudiation or waiver was properly for the court to decide and that the triаl court correctly determined that Haddock repudiated, or in the alternative waived, arbitration of his claims by substantially invoking the judicial process to their detriment. They argue that the trial court correctly concluded that the remaining claims asserted by Haddock, individually and derivatively on behalf of CEI stockholders and against nonsignatories, are not within the scope of the arbitration agreement.
II. Factual and Procedural Background
A. The Parties
1. The Crescent Entities
CEI is a publicly held real estate investment trust (commonly referred to as a “REIT”) organized under the laws of the state of Texas. CEI is structured as an Umbrella Partnership Real Estate Investment Trust whereby CEI owns a majority of the limited partnership interests in CREELP, a Delaware limited partnership. This organizational structure (referred to as an “UPREIT”) allows owners of investment real estate to sell their properties to CREELP in exchange for CREELP units, which the seller may later convert into CEI common stock. The real estate owners incur no income tax liability until they sell the stock. CREE, a Delaware corporation, is a wholly owned subsidiary of CEI and serves as CREELP’s general partner.
2. The Individuals
In 1994, Haddock and two cofounders created the Crescent Entities and related companies. Prior to 1994, Haddock had served in various capacities in companies formed by one of the cofounders, including serving as lead transactional attorney and chief negotiator. Of the individual Real Parties in Interest, John Goff currently *165 serves as CEI’s CEO and Vice Chairman. William Quinn, Paul Rowsey III, and Terry Worrell serve as members of CEI’s Board of Trust Managers.
B.The CREELP Partnership Agreement and Arbitration Clause
In February 1994, Haddock, as CEI’s President, signed a limited partnership agreement on behalf of CEI, CREE, and several limited partners to form the CREELP limited partnership. CREE was CREELP’s general partner. Haddock became a limited partner in CREELP as well as President of CEI, and he became CEO of CEI in 1996. As an officer and senior management employee, Haddock received options to purchase units in CREELP in 1995 and 1996, which were exchangeable for CEI common stock. The options for both the CREELP units and CEI stock were created by incentive plans adopted by those entities’ respective governance committees.
The original CREELP limited partnership agreement did not contain an arbitration agreement. However, in May 1994, the limited partnership agreement was amended to add an arbitration agreement that provides, in pertinent рart: 1
Section 16.1 Arbitration
Notwithstanding anything to the contrary contained in this Agreement, all claims, disputes and controversies between the parties hereto (including, without limitation, any claims, disputes, and controversies between the Partnership and any one or more of the Partners and any claims, disputes and controversies among any two or more Partners) arising out of or in connection with this Agreement or the Partnership created hereby, relating to the validity, construction, performance, breach, enforcement or termination thereof, or otherwise, shall be resolved by binding arbitration in the State of Texas, in accordance with this Article 16 and, to the extent not inconsistent herewith, the Expedited Procedures and Commercial Arbitration Rules of the American Arbitration Association.
The arbitration agreement contains additional paragraphs of detailed procedures to be followed in any arbitration proceedings under the agreement, including an expedited schedule for selection of an arbitration panel, for commencement and completion of the arbitration proceeding within sixty days after selection, and for rendition by the panel of its award within thirty days thereafter.
C. The Severance Agreement
In June 1999, Haddock resigned from his executive positions and entered into a confidential severance agreement with CEI and CREELP, which provided for him to receive certain cash compensation and which, together with simultaneously executed amended unit option and stock option agreements, accelerated the vesting of certain of his CREELP unit options and CEI stock options that he had previously received as part of his compensation. The agreement called for Haddock to relinquish all of his remaining unvested unit options and stock options. Paragraph 13 of the severance agreement (the “unfavorable-comments clause”) restricted both Haddock and the Crescent Entities from making unfavorable comments about the other or about Haddock’s job performance. The severance agreement did not contain an arbitration clause.
D. The Prior Lawsuit
*166 In March 2005, Haddock filed a suit for a declaratory judgment and for temporary and permanent injunctions against the Crescent Entities in the 17th District Court of Tarrant County, Texas. Haddock pleaded his prior status as CEO and President оf CEI, CREE, and other related entities referred to in his petition as “the Employer Group,” that he and the Employer Group had agreed to terminate his employment relationship in June 1999, and that the parties had entered into a confidential severance agreement that he would file under seal with the court. Haddock stated that as consideration for his resignation from all directorships and offices held in the Employer Group, the severance agreement provided that, in addition to stock and units in CEI and CREELP that he already owned, he was promised certain cash compensation as well as the accelerated vesting of certain stock and partnership unit options and that he thereby became immediately vested in a large number of stock and unit options in both CEI and CREELP.
In his petition, Haddock further explained that he had become “concerned” that the Crescent Entities were being managed and operated adversely to interests of shareholders and unitholders by offering executives excessive compensation packages and risky loans that seriously jeopardized the financial health and stability of the entitiеs. Haddock alleged that he desired to discuss these concerns with fellow shareholders and unitholders and to further investigate but feared that doing so might be construed by the Crescent entities as a breach of the unfavorable comments clause in the severance agreement. Haddock alleged that he had received threats that the Crescent Entities would forfeit his options as a result of his conduct in discussing those matters and exposing their “questionable practices.”
Haddock sought to clarify or reform the severance agreement by a declaratory judgment that the unfavorable comments clause of the severance agreement was void or limited to statements rising to the level of actionable defamation. He also sought and obtained a temporary restraining order against the Crescent Entities from “[tjhreatening or taking any action to declare forfeited or interfere with” his lights in any shares of CREE or CREELP, already owned by him or shares or units subject to an unexercised option held by him. The restraining order granted by the trial court also provided that all parties were to abide by the unfavorable-comments clause. The рarties later agreed to an order extending the temporary restraining order until the date of trial, originally scheduled for August 29, 2005.
The Crescent Entities filed a counterclaim asserting that Haddock had breached the terms of both the severance agreement and a subsequent 2001 settlement agreement, general release, and covenant not to sue for claims and causes of action in any way connected with his prior employment or termination.
In June 2005, Haddock filed a motion to clarify or modify the temporary restraining order, alleging that he proposed to exercise his rights as a unitholder in CREELP and the right to have the value of his options adjusted in accordance with “relevant agreements and plans” under which the options were created. Haddock alleged in that motion that he had reason to believe he had one or more common law and statutory causes of action against the Crescent Entities related to management and desired “to assert these claims in this suit, or in another suit.” Haddock requested in his motion that the court remove all doubt that filing those lawsuits would not violate the terms of the sever- *167 anee аgreement and that it either clarify or modify the temporary restraining order to permit him to file the lawsuits.
Haddock subsequently filed two motions for summary judgment, one as to the enforceability of the severance agreement and the other as to the Crescent Entities’ counterclaim; the Crescent Entities likewise moved for summary judgment. After a two-day hearing, the trial court signed a final judgment on December 1, 2005, ordering that Haddock and the Crescent Entities take nothing on their respective claims and counterclaims. Haddock appealed to this court from the take-nothing summary judgment against him, but he later moved to dismiss the appeal, and we dismissed it on April 6, 2006.
See Haddock v. Crescent Real Estate Equities Co.,
No. 02-06-00096-CV,
E. The Arbitration Demand
On December 6, 2005, six days after the trial court signed its final judgment, Haddock wrote to the CEI Compensation Committee, requesting that it adjust the exercise price for his options pursuant to the antidilution provisions of the stock and unit option plans, which request was refused. Thereafter, according to Haddock, CREELP and CEI continually refused to allow him to exercise CREELP unit options and to exchange them for CEI stock.
On July 10, 2006, Haddock filed a forty-three page Statement of Claims with the American Arbitration Association under thе. arbitration provision contained in the CREELP limited partnership agreement. In his Statement of Claims, Haddock asserted causes of action against all of the Crescent Entities as well as the individual Real Parties in Interest for breach of contract, breach of the duty of good faith and fair dealing, violation of securities laws, and breach of fiduciary duty. As in his prior suit, Haddock set forth the events regarding his resignation as director and officer from the Crescent Entities in 1999, and alleged that since that time, those entities’ operations had declined and the entities had begun to liquidate their real estate properties, using the proceeds to continue to award extraordinary dividends to stockholders, thereby diluting the value of his CREELP unit options.
Haddock further alleged that the Entities’ Compensation Committee refused to adjust the exercise price of his options as provided by anti-dilution provisions in the option agreements, prevented him from converting his options to CEI common stock, and refused to allow him to exercise his options with a recourse promissory note as provided by the CREELP unit option agreement, resulting in damages of over $8.2 million. Haddock also asserted a claim, in a derivative capacity on behalf of CEI shareholders, asserting that loans to company insiders violated the Sarbanes-Oxley Act, resulting in damages to the shareholders of at least $39.7 million, including lost interest. He named Quinn, Rowsey, and Worrell as parties based upon their service on a Special Litigation Committee for the Crescent Entities that refused his demand regarding the derivative claim.
F. The Underlying Proceeding
Real Parties in Interest filed this action in the 67th District Court of Tarrant County seeking a stay of the arbitration proceedings and a declaratory judgment that Haddock had repudiated the CREELP arbitration agreement by filing his March 2005 suit and proceeding to a final judgment rather than arbitrating the issues in that case and that the remaining claims were not within the scope of the arbitration agreement. Haddock answered with a general denial and a plea to *168 the jurisdiction asserting that the trial court lacked jurisdiction to decide any issues of arbitrability, including waiver or repudiation. Alternatively, he asserted that even if the court had jurisdiction over some arbitrability issues, its jurisdiction was limited in scope and did not allow it to decide the waiver or repudiation issue.
After a hearing on the application to stay arbitration, the trial court — the presiding judge being the same judge who had earlier entered the temporary restraining order in the prior suit, sitting for the regular judge of the 17th District Court — signed an order granting the stay and permanently enjoining Haddock from pursuing his arbitration demand. After Haddock perfected his appeal in this case, the trial court filed findings of fact and conclusions of law, finding that Haddock had repudiated the CREELP arbitration agreement by litigating the March 2005 suit to a final judgment, that he was es-topped from relying on the arbitration agreement, that Real Parties in Interest accepted that repudiation by defending against Haddock’s claims and filing a counterclaim, and that Real Parties in Interest suffered prejudice.
Haddock seeks review of the trial court’s order both by petition for writ of mandamus and by interlocutory appeal. We have consolidated the two proceedings for a decision disposing of both simultaneously.
See In re Valero Energy Corp.,
III. Discussion
A. Mandamus or Interlocutory Appeal?
The parties agree that the Federal Arbitration Act (“FAA”) applies to the arbitration agreement in this case.
See generally
9 U.S.C. §§ 1-16 (West 2009). A party seeking relief pursuant to the FAA from a denial or stay of arbitration must pursue relief by way of petition for writ of mandamus.
In re D. Wilson Constr. Co.,
B. Standard of Review
Mandamus will issue to correct a clear abuse of discretion for which the remedy by appeal is inadequate.
In re Prudential Ins. Co. of Am.,
A party seeking to enforce an arbitration agreement must establish the existence of a valid arbitration agreement and show that the claims in dispute fall within the scope of that agreement.
In re Bank One, N.A.,
Once the moving party establishes the existence of a valid arbitration agreement, the trial court then determines whether the nonmovant’s claims fall within the scope of the arbitration clause.
In re FirstMerit Bank, N.A.,
C. The Arbitration Agreement
Haddock contends by his first issue that repudiation and waiver are matters of substantive arbitrability and that the parties clearly and unmistakably agreed to have all issues, including questions of arbitrability, decided by an arbitrator. Therefore, he asserts, the trial court lacked jurisdiction to decide the issues of repudiation and waiver. Real Parties in Interest contend that no valid arbitration agreement continued to exist because Haddock “repudiated” it by filing the prior lawsuit. They argue that when Haddock commenced the prior lawsuit, the Crescent Entities were put to an “election” to either terminate or insist on performance of the arbitration agreement and that, by filing a counterclaim and allowing the prior lawsuit to go to final judgment, the Crescent Entities and Haddock mutually terminated the arbitration agreement.
1. The issue is waiver, not repudiation by election.
In findings of fact 2 and conclusions of law that it entered after the par *170 ties filed their briefs in this court and that have not been challenged by either party, the trial court found in favor of Real Parties in Interest that Haddock
repudiated the Arbitration Agreement by filing and prosecuting the Prior Lawsuit to a final judgment. The Crescent Entities accepted that repudiation by defending against Haddock’s claims ... and by prosecuting a counterclaim. The Arbitration Agreement ceased to exist as between these parties on or before April 6, 2006, the date Haddock dismissed his appeal of the Prior Lawsuit. 3
To support their argument that Haddock repudiated the arbitration agreement, Real Parties in Interest rely on
Vireo, P.L.L.C. v. Cates,
Although the Supreme Court of Texas has not spoken on this issue,
Vireo
⅛ approach, that of “mutual repudiation and waiver based on election” when a plaintiff files suit and then seeks arbitration, has been rejected by this court on two occasions as well as by other Texas courts of appeals.
See Grand Homes, 96, LP v. Loudermilk,
In addition to asserting repudiation, Real Parties in Interest contend that Haddock waived the arbitration agreement by inconsistent conduct in the prior lawsuit that resulted in prejudice to them. The trial court made additional findings that Haddock’s conduct in filing and prosecuting the prior lawsuit to final judgment substantially invoked the litigation process and prejudiced the Crescent Entities. In
Perry Homes v. Cull,
handed down after briefs were filed and after submission in this court, the Supreme Court of Texas extensively addressed the defense of waiver of arbitration by substantially invoking the judicial process to the other party’s detriment or prejudice.
*171 2. The trial court has jurisdiction to decide waiver.
As a threshold issue, Haddock argues that the trial court lacked subject matter jurisdiction to decide the issue оf waiver. Federal and state courts have concurrent jurisdiction to enforce the FAA.
In re Palacios,
We recently decided this very issue against Haddock’s position in another case.
Nw. Constr. Co. v. Oak Partners, L.P.,
3. Who decides the question of waiver by inconsistent conduct?
Haddock next argues that who decides the question of waiver is a matter of contract and that the parties to this arbitration agreement clearly and unmistakably referred all questions of arbitrability to an arbitrаtion panel.
6
We agree that “arbitration is a matter of contract.”
Howsam,
There is a “qualification” to that general rule, which is also an exception to the liberal policy favoring arbitration agreements.
Howsam,
In
First Options,
the Supreme Court noted, in discussing the “clear and unmistakable evidence” requirement, that “the law treats silence or ambiguity about the question
‘who
(primarily) should decide ar-bitrability’ differently from the way it treats silence or ambiguity about the question
whether
a particular merits-related dispute is arbitrable because it is within the scope of a valid arbitration agreement,’ ” so as to not “force unwilling parties to arbitrate a matter they reasonably would have thought a judge, not an arbitrator, would decide.”
а. No “clear and unmistakable” evidence of agreement to delegate questions of arbitrability to arbitrator
Haddock argues that the arbitration agreement of the limited partnership agreement “clearly and unmistakably” delegates arbitrability issues, including waiver, to an arbitration panel by expressly incorporating the Commercial Arbitration Rules of the American Arbitration Association (“AAA”). Specifically, Haddock relies upon Rule 7(a) of those rules, which provides that the arbitrator “shall have the power to rule on his or her own jurisdiction, including any objections with respect to the existence, scope, or validity of the arbitration agreement.” American Arbitration Association, Commercial Arbitration Rules and Mediation Procedures, R7, http://www.adr.org/sp.asp?id=22440# R7 (last accessed February 25, 2009).
Real Parties in Interest respond that the supreme court in
Perry Homes
has now decided, contrary to Haddock’s position, that the issue of waiver in a case governed by the FAA is for the court, not an arbitrator.
in
Perry Homes,
the arbitration agreement at issue in that case contained no reference to the AAA rules. And the supreme court in that case noted, albeit in another section of its opinion, that there was no indication in that contract that the parties had “clearly and unmistakably agreed” that the arbitrator should decide arbitrability.
Id.
at 587, n. 15 (citing
First Options,
The majority of courts have concluded that express incorporation of rules empowering the arbitrator to decide arbitrability (including ruling upon his or her own jurisdiction) clearly and unmistakably evidences the parties’ intent to delegate issues of arbitrability to the arbitrator.
See, e.g., Qualcomm Inc. v. Nokia Corp.,
*173
But the majority view does not “mandate that arbitrators decide arbitrability in all cases where an arbitration clause incorporates the AAA rules.”
San Juan Basin,
In
Marie v. Allied Home Mortgage Corp.,
the arbitration clause referred to binding arbitration “any and all disputes, claims (whether in tort, contract, statutory, or otherwise), and disagreements concerning the interpretation or application of this Agreement ...
including the arbitrability of any such controversy or claim.”
The court in Marie did not expressly decide the effect of the incorporation of the AAA rules but broadly held as follows:
We cannot say that the use of the term [arbitrability] here evinces a clear and unmistakable intent to have waiver issues decided by the arbitrator. There are no references to waiver or similar terms anywhere in the arbitration agreement. Neither party should be forced to arbitrate the issue of waiver by conduct without a clearer indication in the agreement that they have agreed to do so. The issue of who would decide such a question is an ‘arcane’ one that employees are unlikely to have considered unless clearly spelled out by the employer.
Id.
The Third Circuit has followed
Marie
in
Ehleiter v. Grapetree Shores, Inc.,
holding that waiver by litigation conduct inconsistent with arbitration is presumptively an issue for the court.
[W]e do not believe that this provision ... evidences a clear and unmistakable intent to have an arbitrator decide procedural questions of arbitrability that arise only after the parties have bypassed a gateway determination of substantive arbitrability by the arbitrator and actively litigated the underlying dispute in court.
Id.
at 222. The court in
Ehleiter
also noted that there was no reference to waiver of arbitration in the agreement.
Id.
That court refused to interpret the agreement’s “silence regarding who decides the waiver issue” as giving arbitrators that power “ ‘for doing so ... [would] force [an] unwilling part[y] to arbitrate a matter [he] reasonably would have thought a judge, not an arbitrator, would decide.’ ”
Id.
(quoting
First Options,
Haddock seeks to distinguish
Marie
on the basis that the conduct constituting waiver arose in the same litigation in that case, as contrasted with the prior litigation instituted by Haddock in a different court.
7
We disagree. The conduct found to constitute waiver in
Marie
was in a separate proceeding in a different litigation forum, the EEOC.
Marie,
Haddock also argues that the First Circuit held that sending the waiver issue to the arbitrator in Marie would be “exceptionally inefficient” given that the case started in court, whereas Haddock claims this matter began with a demand for arbitration so that the issue of waiver could more easily be resolved in that forum. To the contrary, the conduct complained of by Real Parties in Interest started when Haddock instituted and pursued his prior litigation to an adverse decision in court. As the court in Marie recognized, “[i]f the arbitrator were to find that the defendant had waived its right to arbitration], then the case would inevitably end up back in court.” Id. at 13. The same would be true here.
Finally, Haddock argues that Marie did not address the incorporation of the AAA rules into the arbitration agreement. But the court clearly considered that language, because it specifically pointed out that the agreement so stated; yet the court found no clear and unmistakable evidence of intent in the agreement to shift the issue of waiver to the arbitrator. Id. at 14.
Additionally, as in the San Juan Basin and James & Jackson cases, the arbitration agreement here is not unequivocal but contains limiting language with regard to the incorporation of the AAA rules, incorporating those rules “to the extent not inconsistent” with the remainder of the detailed provisions of the arbitration agreement, which contains five sections *175 and ten paragraphs of information prescribing the procedure and scope of any arbitration.
We also note that there is no designation in the arbitration agreement here as to which version of the AAA rules is to apply, the version in existence when the agreement was made or that in existence at the time of the dispute. Haddock acknowledges that the rule now designated as Rule 7(a), upon which he relies, did not exist when the arbitration agreement was added to the limited partnership agreement in 1994. Although, as Haddock points out, the partnership agreement has been amended several times since its inception without change to the arbitration agreement language, we cannot assume from silence in the agreement as to the issue of arbitrability or as to which version of the AAA rules is to apply, that the parties intended to incorporate Rule 7(a), which did not exist when the arbitration agreement was added.
See Marie,
Silence is not “clear and unmistakable evidence” of intent. The agreement is silent as to whether the parties intended to incorporate the current rules, silent as to whether the arbitrator is to decide issues of “arbitrability,” and silent specifically regarding who is to decide waiver, repudiation, or similar matters. We hold that the general reference in the arbitration agreement to the AAA rules, without more, does not clearly and unmistakably manifest these parties’ intent to refer the issue of waiver by litigation conduct to the arbitrator.
b. Substantial invocation of the litigation process still an issue for the court after Howsam
By part of his second issue, Haddock argues that, even if this court concludes that the trial court had power to consider some arbitrability issues, the trial court lacked power specifically to decide the waiver issue, based upon language contained in the United States Supreme Court’s decision in
Howsam v. Dean Witter Reynolds Inc.,
which stated that the “presumption is that the arbitrator should decide ‘allegationfs] of waiver, delay, or a like defense to arbitrability.’ ”
Every federal court that has addressed this issue since Howsam has continued to hold that substantial invocation of the litigation process is a question for the court rather than the arbitrator — including the First, Third, Fifth, and Eighth Circuit. Legal commentаtors appear to agree. So do we.
Id.
at 589;
see JPD, Inc. v. Chronimed Holdings, Inc.,
c. The “No-Waiver” Rule
Haddock also argues that Rule 48-(a) of the AAA rules incorporated into the arbitration agreement is a factor to be taken *176 into consideration in determining whether he waived the agreement. That rule provides, “No judicial proceeding by a party relating to the subject matter of the arbitration shall be deemed a waiver of a party’s right to arbitrate.” American Arbitration Association, Commercial Arbitration Rules and Mediation Procedures, R48, http://www.adr.org/sp.asp?id=22440# R48 (last accessed Febraary 25, 2009). Haddock acknowledges that this rule does not preclude a finding of waiver but argues that this rule, as incorporated into the agreement, is further indication of the parties’ intent to favor arbitration, specifically with regard to waiver.
The presence of such a “no waiver” clause in an arbitration agreement does not alter the ordinary analysis undertaken to determine if a party has waived its right to arbitration by litigation conduct.
PAICO,
We hold that the trial court properly determined that it, rather than an arbitrator, should decide whether Haddock waived the arbitration agreement by filing and prosecuting the prior lawsuit. We overrule Haddock’s first issue. 8
D. Waiver by Prior Litigation Conduct Inconsistent with Arbitration
Having dealt with the preliminary arguments that consumed the vast bulk of the briefing by both sides, we now address the main issue. Haddock contends that the trial court abused its discretion and misapplied the law to the facts by concluding that he waived arbitration by his conduct in initiating and prosecuting the prior lawsuit. Haddock maintains that his prior lawsuit did not assert the same issues raised by his demand for arbitration and that the issue in the prior lawsuit did not “aris[e] out of or in connection with th[e] [Partnership] Agreement or the Partnership” but, instead, arose from an entirely *177 separate contract — the severance agreement — which was not subject to arbitration.
Real Parties in Interest do not contest the validity of the arbitration agreement in the limited partnership agreement. Their position is that the severance agreement is subject to the arbitration agreement contained in the limited partnership agreement that Haddock raised and litigated in the prior litigation, that his conduct in the prior litigation was inconsistent with an intent to arbitrate that claim, and that they suffered prejudice; thus, they argue, Haddock waived his right to arbitrate his current claims.
Whether a party has waived its arbitration rights under the FAA by inconsistent litigation conduct is a question of law that we review de novo.
Perry Homes,
The party asserting waiver bears a heavy burden of proof, and the court must resolve all doubts in favor of arbitration.
In re Bruce Terminix Co.,
Under the FAA, “[a] party waives an arbitration clause by substantially invoking the judicial process to the other party’s detriment.”
In re Citigroup Global Mkts., Inc.,
To demonstrate waiver, the party opposing arbitration must establish both that (1) the party seeking arbitration substantially invoked the judicial process and (2) the party opposing arbitration suffered prejudice thereby.
In re Bruce Terminix,
1. The prior suit substantially invoked the judicial process
Haddock contends that waiver could not have occurred because the prior suit concerned only the unfavorable-comments clause in the severance agreement, which had no arbitration agreement, and that his current arbitration demand asserts entirely different claims that arise only out of a separate contract, i.e., the partnership agreement. Therefore, we first determine whether- — as Real Parties in Interest contend — the prior suit invoked the judicial process regarding the same claims that Haddock now seeks to arbitrate. See id. at 344-47 (holding waiver applies only where the same claim sought to be arbitrated was previously litigated but upholding finding of waiver where jurisdiction of court was previously invoked *178 on all issues). We agree with Real Parties in Interest on this key issue.
Although the severance agreement contains no arbitration clause, the CREELP unit option plan — as amended and attached to the severance agreement — does. Both the prior suit and the arbitration demand concern claims that “aris[e] out of or in connection with” the limited partnership or the limited partnership agreement by virtue of the CREELP unit option plan, which is subject to all terms of the limited partnership agreement. Section 6.26 of the 1996 CREELP Unit Option Incentive •Plan, attached as an appendix to Haddock’s severance agreement, expressly provides that “the rights granted thereunder are governed by and subject to each of the terms and conditions of the partnership agreement.” That option plan further provides that upon exercising an option thereunder, each participant is “deemed to have accepted and agreed to be bound by each of the terms and conditions of the Partnership Agreement for all purposes.” [Emphasis added.] As amended in 1994 and thereafter, the partnership agreement, in turn, contains the arbitration agreement under which Haddock seeks to arbitrate his CREELP unit option and his CEI stock option claims. 9
While Haddock claims that he initially sought only to reform the unfavorable-comments clause of the severance agreement in the prior lawsuit, he had a stated purpose for doing so — so that he could plead and litigate his claims of risky loans and mismanagement of the Crescent Entities, which allegedly resulted in devaluing his CREELP and CEI options, without fear of violating that clause. Moreover, he also sought and obtained affirmative in-junctive relief against the Crescent Entities, preventing them from threatening or taking action to forfeit his rights in the CREELP unit options vested in him by the severance agreement. Haddock expressly stated his intent to file an additional suit to assert his claims against the Crescent Entities or, alternatively, to assert those claims in that same suit, and he sought the protection of the court through a ruling that he would not risk interference or forfeiture of his options by proceeding with his proposed litigation.
Only after ultimately suffering an adverse result in his suit did Haddock turn to arbitration. Haddock alleged in his arbitration demand that the option claims he now asserts in that demand are “covered by the arbitration provision in the Limited Partnership Agreement.” 10 The fact is that both his prior suit and his arbitration demand assert the same conduct of Real Parties in Interest, namely, allegedly refusing to honor and reducing in value his CREELP unit options and CEI stock options.
Haddock cannot have it both ways. If, as he says, his claims regarding option rights asserted in his arbitration demand are covered by the arbitration agrеement, then so were the claims regarding the *179 option rights that he sought to protect in the previous lawsuit and planned to litigate once he obtained a declaration that the unfavorable-comments clause of his severance agreement did not preclude such a suit. By his prior lawsuit, Haddock invoked the judicial process with respect to the same claims specifically regarding his options in CREELP that he now seeks to arbitrate.
Was his invocation of the judicial process in the prior litigation “substantial”? Waiver by litigation conduct must be decided under a totality-of-the-circumstances test on a case-by-case basis.
Perry Homes,
Real Parties in Interest assert that Haddock “substantially” invoked the judicial process with respect to his claim regarding his rights in the CREELP unit options because
(1) Haddock chose to file the prior lawsuit in court rather than arbitrate (“whether the movant was the plaintiff (who chose to file in court) or the defendant (who merely responded)”);
(2) Haddock filed the prior lawsuit in March 2005, pursued it through final judgment, appealed it to this court, and waited until July of 2006 to file his demand for arbitration (“how long the movant delayed before seeking arbitration”);
(3) Haddock was “the primary signatory on the First Amended Limited Partnership Agreement” and “intended for the arbitration agreement to be broad and encompass all claims and disputes (“whether the movant knew of the arbitration clause all along”)”;
(4) Haddock knew of the arbitration agreement in 1994 when he signed the First Amended Limited Partnership Agreement (“when the movant knew of the arbitration clause”);
(5) Haddock was the plaintiff in the pri- or lawsuit and filed two motions for summary judgment (“whether the mov-ant filed affirmative claims and disposi-tive motions”); and
(6) Haddock pursued the prior lawsuit to a final judgment (“whether the mov-ant sоught judgment on the merits”).
Haddock does not dispute these facts. Haddock chose to file his prior suit rather than to arbitrate, sought and obtained affirmative relief, and expressed his intent to pursue his claims in that lawsuit or in another suit as to mismanagement and refusal of the Crescent Entities to allow him to exercise his options. Throughout the prior litigation, Haddock never mentioned the arbitration agreement under which he now seeks to arbitrate his option claims. Yet he was clearly aware of it because he admits in his brief in this court that he desired that it be included in the limited partnership agreement in 1994.
Further, waiver may be found where a party has tried and failed to achieve a satisfactory result before turning to arbitration.
See, e.g., Oak Partners,
Indeed, failing to seek arbitration until after proceeding in litigation to an adverse result is the clearest form of inconsistent litigation conduct and is inevitably found to constitute substantial invocation of the litigation process resulting in waiver.
See, e.g., Jones v. Citibank (S.D.), N.A.,
Haddock filed his arbitration demand after filing suit, obtaining injunctive relief, litigating for some nine months, filing two motions for summary judgment, and finally suffering an adverse result in the prior lawsuit. All of these facts support the trial court’s finding that he substantially invoked the litigation process and thereby waived his right to arbitration.
Moreover, participation in litigation to gain an advantage in future litigation can result in waiver.
See In re Christus Spohn Health Sys. Corp.,
Haddock filed his arbitration demand for his option claims over a year and a half after filing suit, prosecuting that suit, suffering an adverse summary judgment in the trial court, and after dismissing his appeal to this court. Considering the totality of the circumstances as articulated in Perry Homes, we hold that Haddock substantially invoked the judicial process.
2. Prejudice
Substantially invoking the judicial process does not waive a party’s arbitration rights unless the opposing party also proves that it suffered prejudice as a result.

■[39,40] “Prejudice” has many meanings.
Perry Homes,
Ultimately, what constitutes waiver of the right to arbitrate depends on the facts of each case.
PAICO,
If a party has asserted the right to arbitrate at or before commencement of litigatiоn, the party opposing arbitration will necessarily carry a heavy burden to show waiver.
Id.
Conversely, when a party fails to demand arbitration and also engages in pretrial activity inconsistent with the intent to arbitrate, the opposing party seeking to show waiver “may more easily show that its position has been compromised, i.e., prejudiced.”

Haddock failed to seek arbitration before initiating the prior litigation. Then he waited over fourteen months before requesting arbitration, from March 2005, when he filed the prior lawsuit, until July 2006, when he filed his statement of claims with the AAA. During that time, among other things, he obtained a temporary injunction, filed two motions for summary judgment, litigated his claims to an adverse judgment, and filed and dismissed an appeal from that judgment. The trial court specifically found that the “Crescent Entities were prejudiced by Haddock’s invocation of the judicial system in the Prior Lawsuit. In reliance on Haddock’s actions, the Crescent Entities spent substantial sums defending Haddock’s claims in the Prior Lawsuit and prosecuting a counterclaim.” Haddock has not challenged that finding.
We hold that the trial court did not abuse its discretion by staying the arbitration because Haddock made his choice: he substantially invoked the judicial process as to his option claims to the prejudice of Real Parties in Interest in the prior litigation and thereby waived his right to arbitrate those claims. We overrule Haddock’s third issue.
IV. Conclusion
Haddock does not challenge the trial court’s ruling that his claims based on his stock options in CEI or his Sarbanes-Oxley claim are beyond the scope of the arbitration agreement. Nor has he raised an issue on appeal as to the trial court’s ruling that his claims against Quinn, Row-sey, and Worrell are beyond the scope of the arbitration agreement. Therefore, we need not reach the propriety of the trial court’s order as to those claims. Having overruled Haddock’s three issues, we deny the petition for writ of mandamus, and we dismiss the interlocutory appeal for want of jurisdiction.

Notes
. Each of several amended partnership agreements contain the identical arbitration provision.
. When an abuse of discretion standard of review applies to a trial court's ruling, findings of fact and conclusions of law aid us in reviewing the propriety of the ruling by providing us with an explanation for the ruling.
Chrysler Corp. v. Blackmon,
. The facts in this case are undisputed. Relator’s position is that the trial court misapplied the law to the facts and abused its discretion.
See In re Dillard Dep't Stores, Inc.,
. Indeed, Haddock has argued from the outset that “repudiation” and "waiver” in the сontext of a party's litigation conduct that is *171 inconsistent with arbitration have no substantive difference.
. Although the trial court did not make an explicit finding or conclusion as to whether it possessed the power to determine the issue of waiver, it implicitly so concluded because it proceeded to determine the essential elements of waiver against Haddock.
. The limited partnership agreement requires that Delaware law be used when construing the agreement, specifically including the arbitration agreement. The parties agree that, to the extent that any state substantive law applies, Delaware law "mirrors federal law.” When applying the FAA, Texas courts also look to federal law to decide substantive issues.

. Haddock does not discuss the differences between or attempt to distinguish Ehleiter or James & Jackson from this case.
. We also overrule the second part of Haddock's second issue, in which he argues that whether the arbitration agreement forbids his Sarbanes-Oxley derivative claim is for the arbitrator to decide, not the court, similar to a like issue regarding class arbitration under
Green Tree Financial Corp. v. Bazzle,
. The trial court found, and Haddock has not challenged that finding, that he raised some of the. same issues in the prior suit that he now seeks to arbitrate, alleging in his petition in that suit that the Crescent Entities "may be acting adversely to the interests of stockholders and unitholders” and that "Haddock further believes the management of the Employer Group is not acting in the best interests of the shareholders and unitholders by providing risky loans to executives which seriously jeopardize the financial health and stability of the Employer Group.”
. Although Haddock points out that he had and retains to this day a limited partnership interest in CREELP, he has never explained how the arbitration demand involves that limited partnership interest, other than through the identical options that were involved in the prior suit.
