OPINION
Opinion by
Appellants, the State of Texas, the Texas General Land Office, and the Texas Land Commissioner, bring this accelerated *230 interlocutory appeal following the trial court’s denial of their plea to the jurisdiction. 1 Appellants contend that the trial court erred in denying its plea to the jurisdiction because (1) appellee, Herbert Holland, failed to adequately plead a cause of action for inverse condemnation; and (2) the State acted under color of contract, and therefore, no takings claims can be brought as a matter of law. We affirm.
I. FACTUAL AND PROCEDURAL BACKGROUND
Over the past several years, the Texas General Land Office has worked to abate oil pollution in areas of the Gulf of Mexico by constructing filtration units along the Texas coast. Specifically, the State has been involved in the construction of these facilities at Port Isabel, Palacios, and Port Lavaca, Texas. The filtration units use a series of special polymer-based filters to remove the pollution. Holland holds the patent for those filters and for the filtration process.
In 2002, Holland sent a letter to the State claiming the State had infringed on his patent and requesting payment for the use of his patented technology. After the State refused to pay, Holland filed suit, asserting inverse condemnation under article I, section 17 of the Texas Constitution. The State responded with a general denial and a pléa to the jurisdiction arguing that the trial court lacked jurisdiction because sovereign immunity barred Holland’s claim, there was no intentional act as required in a takings claim, the plaintiffs case was pre-empted by federal law, and Texas does not recognize a takings claim for patent infringement. The State also asserted immunity from suit because Holland had allegedly brought a contract claim disguised as a patent infringement claim.
On February 5, 2004, the trial court held a hearing on the State’s plea to the jurisdiction. After reviewing the pleadings, affidavit evidence and testimony from the parties, the trial court denied appellants’ plea to the jurisdiction. This appeal ensued.
II. STANDARD OF REVIEW
A plea to the jurisdiction is a dilatory plea; its purpose is “to defeat a cause of action without regard to whether the claims asserted have merit.”
Bland Indep. Sch. Dist. v. Blue,
When a plea to the jurisdiction challenges the pleadings, we. determine if the pleader has alleged facts that affirmatively demonstrate the trial court’s jurisdiction to hear the cause.
Tex. Ass’n of Bus. v. Tex. Air Control Bd.,
III. ANALYSIS
Holland’s first amended petition asserts an inverse condemnation claim pursuant to article I, section 17 of the Texas Constitution.
See
Tex. Const, art. I, § 17. Section 17 provides that “no person’s property shall be taken, damaged or destroyed for or applied to public use without adequate compensation being made.... ”
Id.
Condemnation is the procedure by which a sovereign state exercises its right to take property of a private owner for public use, without consent, but upon the payment of just compensation.
AC. Aukerman Co. v. State,
Generally, sovereign immunity, unless waived, protects the State of Texas, its agencies and its officials from lawsuits for damages, absent legislative consent to sue the State.
Fed. Sign v. Tex. S. Univ.,
A. Inverse Condemnation Pleading
Appellants first contend that the trial court erred in denying their plea to the jurisdiction because Holland failed to adequately plead a cause of action for inverse condemnation and therefore, sovereign immunity is not waived. To plead a cause of action for inverse condemnation, Holland was required to assert that his property was taken, damaged or destroyed for or applied to public use.
See A.C. Aukerman,
Holland’s first amended petition alleges, in relevant part, the following:
9.The practice of the method used by the [General Land Office] and the use of the apparatus are physical acts that constitute an invasion of Plaintiff’s property right.
10. The practice of the method used by the [General Land Office] and the use of the apparatus are physical acts that constitute an unreasonable interference with Plaintiffs exclusive right to use and enjoy his . property.
11. The acts of the [General Land Office], constitute a taking of Plaintiffs property without just compensation.
12. Plaintiffs property has been taken by the [General Land Office] for or applied to public use.
13. The acts by the [General Land Office], which have resulted in the taking of Plaintiff’s property, were done intentionally and are continuing to be- done intentionally.
*232 (Emphasis added). Looking at the allegations in Holland’s petition, it is clear that he properly pled the elements of an inverse condemnation claim.
Appellants contend that Holland’s allegations are insufficient to plead a “taking” within the meaning of article I, section 17 because Holland has not provided proof that his property has been destroyed or damaged. We note that “taking,” “damaging,” and “destruction” of one’s property are three distinct claims arising under article I, section 17, although the term “taking” has become used as a shorthand to refer to all three types of claims.
City of Dallas v. Jennings,
Additionally, appellants argue that Holland’s petition does not assert that the State had the requisite intent for an inverse condemnation claim. In support of this argument, appellants cite to
Jennings,
Accordingly, looking at the allegations in the pleadings, accepting them as true, and construing them in favor of the pleader, see Brown, 80 S.W.3d at 555, we conclude Holland’s petition clearly states a claim for inverse condemnation. Appellants’ first issue is overruled.
B. Existence of a Contract
By their second issue, appellants argue that the trial court should have granted the State’s plea to the jurisdiction based on the State’s evidence that an implied-in-fact contract existed with Holland’s companies for the construction and use of the Palacios facility. When the State acts within a color of right under a contract and not under its eminent domain powers, the State does not have the requisite intent under constitutional-takings jurisprudence.
See Gen. Servs. Comm’n v. Little-Tex Insulation Co., Inc.,
If a plea to the jurisdiction challenges the existence of jurisdictional facts, we consider relevant evidence submitted by the parties when necessary to resolve the jurisdictional issues raised, as the trial court is required to do. Tex. Dep’t Parks & Wildlife v. Miranda, 133 *233 S.W.3d 217, 227 (Tex.2004). When the consideration of a trial court’s subject matter jurisdiction requires the examination of evidence, the trial court exercises its discretion in deciding whether the jurisdictional determination should be made at a preliminary hearing or await a fuller development of the case, mindful that this determination must be made as soon as practicable. Id. In a case in which the jurisdictional challenge implicates the merits of the plaintiffs cause of action and the plea to the jurisdiction includes evidence, the trial court reviews the relevant evidence to determine if a fact issue exists. Id. If the evidence creates a fact question regarding the jurisdictional issue, then the trial court cannot grant the plea to the jurisdiction, and the fact issue will be resolved by the fact finder. Id. However, if the relevant evidence is undisputed or fails to raise a fact question on the jurisdictional issue, the trial court rules on the plea to the jurisdiction as a matter of law. Id.
The evidence introduced by appellants at the hearing included invoices, purchase requisitions and other correspondence between the General Land Office and the two companies owned by Holland, Spill Removal Products and Pollution Prevention Services. This evidence shows that the State paid money to Holland’s companies for the components, installation, design and consulting for the Palac-ios facility. Additionally, the State introduced the testimony of Dale Smith who testified as to the existence of a contractual relationship between the State and Holland’s companies. However, there is little evidence supporting the existence of a contract with Holland, the owner of the patent. The State’s own witness acknowledged that there was no contract with Holland.
Based on the evidence presented by appellants, this Court cannot conclude as matter of law that an implied contract existed between the State and Holland regarding the use of Holland’s patented filtration process. Accordingly, we find that a fact issue exists as to the existence of a contract which must be resolved by the fact finder.
See Haws & Garrett Gen. Contractors, Inc. v. Gorbett Bros. Welding Co., Inc.,
IV. CONCLUSION
Having found that Holland’s pleadings contain sufficient facts to affirmatively demonstrate the trial court’s jurisdiction and that the existence of an implied contract between the parties is a fact issue which must be determined by the finder of fact, we accordingly affirm the decision of the trial court.
