The Board of Regents of the University of Texas System, Petitioner,

v.

IDEXX Laboratories, Inc., Respondent

═══════════════════════════════════════ On Petition for Review from the Court of Appeals for the Fourteenth District of Texas ═══════════════════════════════════════

Argued January 10, 2024

CHIEF JUSTICE HECHT delivered the opinion of the Court.

A contract is a written expression of the parties’ intent. When that intent is in question, the text must be read “as a whole in light of the circumstances present when the contract was entered.” 1 In this case, the court of appeals concluded that two royalty provisions in the parties’ licensing agreement, one for 1% and the other for 2.5%, considered separately and in the abstract, could logically be read to apply to the

1 Columbia Gas Transmission Corp. v. New Ulm Gas, Ltd., 940 S.W.2d

587, 589 (Tex. 1996). same sales of goods. Viewing both interpretations as “equally reasonable”, the court held the agreement to be ambiguous. 2 But obviously, in negotiating their agreement, the parties must have intended that the provisions, for very different royalties, would apply in different and mutually exclusive situations. The differing interpretations are, as we recently described in another context, “merely the competing theories that the parties advanced about how to read the text”. 3 Examining the royalty provisions in context and in light of the circumstances that produced them, we find no ambiguity. We therefore reverse and remand to the court of appeals to address the remaining issues. I Lyme disease in humans is caused by the bacterium Borrelia burgdorferi, which is carried by certain ticks. A skin rash near the tick bite may indicate infection. Early symptoms include joint and muscle pain, headaches, fever, and fatigue. The disease isn’t contagious; it’s spread only through a tick bite. Most cases can be treated successfully with antibiotics. Without treatment, the disease can worsen and result in severe pain and impairment. Dogs can contract Lyme disease, but most cases are routine and asymptomatic, not requiring treatment. Heartworm is a serious and often fatal disease in pets, mostly dogs, caused by a parasitic worm, Dirofilaria immitis, carried by mosquitoes. When an animal is infected, the worm resides in blood

2 vessels near the heart and lungs and multiplies, inhibiting breathing and blood flow. The disease isn’t contagious; it’s spread only through a mosquito bite. Regularly administered prescription preventives can protect an animal from the parasite, but if given after the animal is infected, the medication can itself result in impairment and death. So it’s important to determine whether a dog has heartworm disease before giving the dog a preventive, like a heartworm pill. The parasite’s presence can be detected with a blood test. IDEXX Laboratories, Inc. (“Labs”) has long been involved in developing, manufacturing, and selling veterinary diagnostic tests, products, and services. Labs invented heartworm tests in the 1980s and in 1992 offered its first “SNAP” product, a single-use device to test a dog’s blood quickly and easily for heartworm without laboratory processing. A small sample of blood is placed in one part of the device and a chemical solution in another. Then at the press of a button, the device snaps them together (hence the name). Within eight minutes, the result shows whether the dog has the antigen for heartworm. The SNAP product was a success and quickly made Labs an industry leader in the market for heartworm tests. But its success and the seriousness of heartworm disease encouraged others to develop competing tests, prompting Labs to look for ways to distinguish its SNAP product. At one point, it added a test for a tickborne pathogen, E. canis, which causes ehrlichiosis, 4 calling the product the SNAP Canine

dogs, cats, and people.

3 Combo. Continuing its diversification efforts, Labs sought to obtain an exclusive license to use a peptide newly discovered at Tulane University to test for Lyme disease. In the process, Labs learned that The University of Texas (“the University”) had applied for a patent on the same peptide. To assure its exclusive use, Labs also obtained an exclusive license of the University’s patent. In determining the royalties it would pay, Labs discussed with the University the sorts of products it might develop by combining the Lyme disease test with tests for other tickborne diseases and Labs’ flagship heartworm test. The parties attempted to assess what test combinations could be most profitably and successfully marketed. After much discussion and many proposals back and forth, the parties signed a lengthy patent license agreement in 2000 calling for royalties on three types of products depending on what tests were included. Boiled down to its essentials, paragraph 5.1(b) obligated Labs to pay quarterly, on net sales for products sold (i) “to detect Lyme disease alone” — 4%; (ii) “to detect Lyme disease in combination with one other veterinary diagnostic test . . . (for example, but not limited to, a canine heartworm diagnostic test . . .)” — 1%; and (iii) “to detect Lyme disease in combination with one or more veterinary diagnostic products . . . to detect tick-borne disease(s)” — 2.5%. 5

5 Paragraph 5.1(b) stated:

In consideration of rights granted by Board [of Regents of The University of Texas System] to IDEXX under this Agreement, IDEXX agrees to pay . . . a running royalty as follows:

4 The 1% royalty under (b)(ii) was to be shared equally with Tulane. The 2.5% royalty under (b)(iii) was not. The University’s patent was to expire in 2017. Shortly after executing the agreement, Labs introduced its first SNAP product testing for Lyme disease, adding that test to its SNAP Canine Combo. SNAP3Dx tested for Lyme disease and E. canis, two tickborne diseases, as well as mosquito-borne heartworm. Over the years, Labs marketed two other SNAP products. The first added a test for another tickborne disease and the second added tests for two more. 6 Thus, these three SNAP products test for Lyme disease with one, two, or four other tickborne diseases, and all test for mosquito-borne heartworm. None of the products test for a non-tickborne disease other

i. Four percent (4.0%) of Net Sales for all Licensed Products Sold to detect Lyme disease alone. ii. One percent (1.0%) of Net Sales for all Licensed Products Sold to detect Lyme disease in combination with one other veterinary diagnostic test or service (for example, but not limited to, a canine heartworm diagnostic test or service). Such royalty rate shall be reduced by a percentage rate equal to the percentage rate paid to a third party, other than sublicensees and Affiliates, for products or components used by IDEXX exclusively in the production or Sale of the Licensed Product, However, the total reduction of the royalty rate shall not exceed one-half percent (0.5%). iii. Two and one-half percent (2.5%) of Net Sales for all Licensed Products Sold as a product or service to detect Lyme disease in combination with one or more veterinary diagnostic products or services to detect tick-borne disease(s). 6 SNAP4Dx added a test for tickborne E. equi, which also causes ehrlichiosis. SNAP4Dx Plus added tests for tickborne E. ewingii, another cause of ehrlichiosis, and A. platys, which causes anaplasmosis, a disease in the ehrlichiosis family.

5 than heartworm. From the beginning, Labs paid, and the University accepted, a 0.5% royalty under (b)(ii) on sales of all three SNAP products.
