*380 Opinion
In June 2002, after a jury trial, plaintiff City of Hope National Medical Center (City of Hope) obtained a judgment against defendant Genentech, Inc. (Genentech), for breach of fiduciary duty and for breach of contract. 1 The judgment awarded City of Hope $300,164,030 in compensatory damages and $200 million in punitive damages. The Court of Appeal affirmed. Genentech challenges that affirmance.
In this complex case, which has 25,567 pages of reporter’s transcript plus 12,267 pages of clerk’s transcript and has generated 18 friend of the court briefs, the primary issue is whether, as the jury found, a fiduciary relationship necessarily arose when City of Hope, in return for royalties, entrusted a secret scientific discovery to Genentech to develop, to patent, and to commercially exploit. Our answer is “no.” That conclusion invalidates the jury’s punitive damages award, which was based on City of Hope’s tort claim for breach of fiduciary duty. In addition, that conclusion requires us to determine whether the evidence that City of Hope introduced at trial to prove that Genentech had breached a fiduciary duty so prejudiced the jury as to require setting aside the jury’s award of compensatory damages for breach of contract. Here too, our answer is “no.”
Genentech also asserts the trial court erred by (1) submitting interpretation of the contract to the jury; (2) instructing the jury that if, after applying other rules of interpretation, “there remains an uncertainty in the language of the contract, that language must be interpreted against the party who caused the uncertainty to exist”; and (3) admitting evidence of the resolution of a prior dispute between the parties. We conclude that the trial court did not err in any of those three instances.
We affirm that part of the judgment awarding City of Hope $300,164,030 in damages for Genentech’s breach of contract. Because punitive damages cannot be awarded for breaching a contract, however, our conclusion that there was no fiduciary relationship requires us to set aside the jury’s award of $200 million in punitive damages to City of Hope.

A. Parties’ Initial Contacts and Negotiations
In the mid-1970’s, Drs. Arthur Riggs and Keichi Itakura, two scientists employed by plaintiff City of Hope, developed a groundbreaking process for *381 genetically engineering human proteins, enabling the production of large quantities of various medicines of great therapeutic and commercial value. By 1976, Riggs and Itakura began preparing a confidential grant application relating to their scientific discovery. As they neared completion of the application, Dr. Herbert Boyer, a leader in the field of genetic engineering who had previously worked with Drs. Riggs and Itakura, telephoned Riggs in early 1976 and learned of the scientific discovery by Riggs and Itakura. In February 1976, Drs. Riggs and Itakura filed their confidential grant application with the National Institutes of Health. Soon thereafter, in April 1976, Dr. Boyer and venture capitalist Robert Swanson incorporated defendant Genentech, Inc. (Genentech), to commercially exploit biotechnology.
In May 1976, Swanson, Genentech’s president, sent City of Hope a proposal to provide funding to City of Hope to use the scientific process of Drs. Riggs and Itakura to complete the process of synthesizing two proteins, somatostatin and insulin, and to secure patents “necessary for commercialization” as each product was developed. Discussions then followed between Swanson and City of Hope’s patent lawyer John Hall concerning a possible agreement. On June 25, Hall sent Swanson a “Summary of Points for Agreement Between Genentech, Inc. and City of Hope,” with a copy to Genentech patent lawyer Tom Kiley. On June 30, 1976, Genentech’s Swanson and Kiley met with City of Hope’s Hall to further discuss contract issues. Thereafter, on July 22, Genentech sent City of Hope a draft of an agreement that Genentech had prepared. The accompanying cover letter noted that the draft agreement, in Article 6.01, left blank the royalty rate to be paid to City of Hope because Genentech was considering City of Hope’s proposal of a 2 percent flat rate.
After the parties discussed the draft, Genentech on July 28, 1976, sent City of Hope a second draft agreement. The cover letter mentioned that Article 6.01 now included sales by Genentech’s affiliates and payment of 2 percent royalties to City of Hope. Unchanged was Article 6.09, providing that Genentech would obtain from its licensees and pay to City of Hope the “same royalty” that City of Hope would receive if Genentech itself were to carry out the licensed activity.
B. Contract Between Genentech and City of Hope
On August 5, 1976, Genentech and City of Hope executed the contract. Below, we summarize the provisions pertinent here.
Article 1.03 sets forth the general objectives of the parties. As to Genentech, it states: “GENENTECH proposes to engage in the manufacture and sale of certain polypeptides. To do so, it requires synthetic DNA which codes for the *382 production of a particular polypeptide when incorporated in a bacterial or other plasmid.” The article then mentions that City of Hope has laboratory facilities with personnel qualified to synthesize DNA for selected polypeptides, that Genentech would provide funding for that process and would use the resulting DNA in the manufacture of polypeptides, and that Genentech would secure and hold patents “as may emerge from that work.” As to City of Hope, Article 1.03 states: “For its part, CITY OF HOPE wishes to conduct DNA synthesis and related work with GENENTECH funding, to publish the results of such work, and to earn royalty income from GENENTECH sales of polypeptides in whose manufacture synthetic DNA is employed.”
Article 3 of the contract describes the financial support Genentech was to provide to City of Hope, including funding for salaries, materials, and equipment. Article 3.04 states: “The parties contemplate that GENENTECH will solely and exclusively own such patent or other proprietary property as emerges from the work performed by CITY OF HOPE under this agreement. . . .”
Article 5 grants Genentech the sole option to seek patents, but it also gives City of Hope the right to seek patents if Genentech either fails to do so or abandons a patent application.
Article 6.01 reads: “GENENTECH shall pay to CITY OF HOPE a royalty of two percent (2%) of the net sales of all polypeptides sold by it or its affiliates, provided only that manufacture of the polypeptide employ DNA synthesized by CITY OF HOPE under this Agreement and provided to GENENTECH by CITY OF HOPE, or replications of that DNA.” (Italics added.) (The italicized language is referred to by the parties as “the DNA use requirement.”)
Article 6.02 states: “For the period commencing with the effective date of this Agreement and ending five (5) years thereafter, GENENTECH will pay to CITY OF HOPE the royalty provided for in Article 6.01 hereof regardless of whether GENENTECH has secured one or more patents on Developments. Thereafter, GENENTECH’s royalty obligations under Article 6.01 shall be limited to the payment of royalty only in respect to such manufacture, use or sale which would infringe the claims of an issued GENENTECH patent on Genentech developments in the country of manufacture, use or sale, but for GENENTECH’s ownership of the patent, and provided further that the patent has not been finally adjudicated as invalid or unenforceable by a court of competent jurisdiction.” (Italics added.) (The italicized language is referred to by the parties as “the patent infringement requirement.”)
Article 6.08 provides: “Should GENENTECH license any third party under any patent acquired by it hereunder, then GENENTECH shall secure from *383 that party and pay to CITY OF HOPE the same royalty CITY OF HOPE would have received had GENENTECH itself carried out the licensed activity.”
Article 7 pertains to the infringement of patents. Article 7.02 states: “Should GENENTECH recover from any infringer, whether by way of settlement or judgment, damages or profits for infringement of any patent secured by it under this Agreement, then after deduction from such recovery of GENENTECH’s reasonable expenses in effecting the same, the balance shall be treated as net sales of GENENTECH for royalty purposes.”
In Article 8, Genentech agrees to compute and pay royalties to City of Hope quarterly, “to keep regular books of account in sufficient detail to permit the royalties payable hereunder to be determined,” and to permit City of Hope to inspect Genentech’s books and related records.
Article 10.01 grants Genentech the right to assign and transfer its contractual rights, including patents and patent licenses. Article 10.02 grants City of Hope the right to assign and transfer its rights to payments from Genentech.
Finally, Article 11.01 states: “Nothing herein contained shall be deemed to create an agency, joint venture or partnership relation between the parties hereto. It is agreed that the relationship between the parties is such that CITY OF HOPE in its performance of this Agreement is an independent contractor.”
C. Parties’ Actions After Contract’s Execution
The collaboration between Genentech and City of Hope resulted in extraordinary scientific and commercial success. The groundbreaking scientific developments by City of Hope’s Drs. Riggs and Itakura enabled Genentech to obtain a number of patents based on that scientific discovery. Based on these patents, Genentech granted licenses to various companies.
Genentech informed City of Hope that in August 1978 it had granted Eli Lilly and Company (Eli Lilly) a license to produce human insulin. But Genentech did not tell City of Hope about other licenses it had granted, such as one it granted to other companies for the production of interferon, which was then viewed as a potential cure for cancer and the sales of which Genentech projected as potentially exceeding its revenue from all other sources combined.
In its October 14, 1980, prospectus for its initial public offering of stock, Genentech described its royalty obligation to City of Hope as “contingent upon the existence of one or more patents arising from the funded research *384 which would, but for Genentech’s ownership of the patent(s), be infringed by the activities underlying the royalty payment.”
On October 24, 1986, Dr. Eric Jurras of City of Hope wrote a letter to Kiley, by then Genentech’s general counsel, requesting, among other things, “a list of all products Genentech had produced or is now producing which involve any methods of genetic engineering or replication of DNA provided to Genentech by City of Hope,” as well as a list “of companies Genentech has third party licenses with which relate to methods of genetic engineering or DNA provided to Genentech by the City of Hope.” In November 1986, Dr. lurrus and Ed Irons, an attorney for City of Hope, met with Genentech’s Kiley. Thereafter, Irons wrote three letters to Genentech requesting unspecified documents, which, at the November meeting, Kiley apparently had promised to produce. In April 1987, Irons traveled from City of Hope’s headquarters in Duarte, in Southern California, to Genentech’s headquarters in South San Francisco, where he reviewed files from a patent application; Kiley had told a subordinate not to show Irons any third party licenses.
By the late 1980’s and early 1990’s, Genentech had obtained a large number of United States and foreign patents in which City of Hope’s scientists Riggs and Itakura were identified as the inventors, and Genentech had entered into a substantial number of licensing agreements with third parties, including companies such as Eli Lilly, Hoffman-La Roche, Monsanto Company, and Boehringer Ingelheim. City of Hope received $302 million in royalties on Genentech’s sales and on sales by Genentech’s licensees of somatostatin, insulin, and a human growth hormone that used DNA synthesized by City of Hope. But City of Hope received no royalties from sales by Genentech and by Genentech’s licensees of other products, such as interferon and hepatitis B vaccine, that were based on the genetic engineering technique pioneered by City of Hope scientists Riggs and Itakura but did not use DNA synthesized by City of Hope.
On an unknown date in the 1990’s, Genentech sued Eli Lilly, alleging infringement of the Riggs-Itakura patents by producing and selling human growth hormone. In December 1994, the two parties settled the lawsuit. As part of the settlement, Eli Lilly agreed to pay Genentech approximately $145 million, as well as a 6 percent royalty on future sales of human growth hormone. City of Hope then asserted that under Article 7.02 of its contract with Genentech it was entitled to 2 percent of Genentech’s $145 million patent infringement settlement with Eli Lilly and a 2 percent royalty on Eli Lilly’s future sales of human growth hormone. After initially rejecting City of Hope’s claim, Genentech agreed to pay City of Hope $3 million and a 1.75 percent royalty on Eli Lilly’s future sales of human growth hormone.
*385 In 1998, Genentech settled for $20 million a lawsuit it had brought against a group of companies collectively called Novo Nordisk for infringing the Riggs-Itakura patents. When Genentech rejected City of Hope’s claim for a share of that settlement, City of Hope brought this action against Genentech.
D. The Lawsuit in This Case
On August 13, 1999, City of Hope sued Genentech for breach of fiduciary duty and for breach of contract, including breach of the implied covenant of good faith and fair dealing. At the first trial the jurors were unable to reach a verdict, voting seven to five in favor of Genentech. The case was then retried.
At the retrial, the parties presented conflicting extrinsic evidence concerning the meaning of various contractual provisions and the parties’ intent relating to the contract. City of Hope maintained that the DNA use requirement in Article 6.01 (that the manufacture of the polypeptides use DNA synthesized and provided by City of Hope) and the patent infringement requirement of Article 6.02 (that royalties to City of Hope were to be limited to the manufacture, use, or sale that would infringe Genentech patents) did not apply to licenses granted by Genentech or monies received by Genentech in resolving Genentech’s infringement claims against certain companies. City of Hope further asserted that its royalty rights did apply to products made by Genentech licensees using the genetic engineering techniques protected by the Riggs-Itakura patents. Genentech, on the other hand, argued that the DNA use requirement and the patent infringement requirement applied to Article 6.08’s provision concerning licensing to third parties, as well as to Article 7.02’s provision pertaining to Genentech’s monetary recoveries for the infringement of patents by certain companies.
The jury found that Genentech had breached the contract with City of Hope, breached its fiduciary duty to City of Hope, and acted with fraud and malice. It awarded City of Hope compensatory damages of $300,164,030 (the exact amount City of Hope had claimed as unpaid royalties it was owed by Genentech), and $200 million in punitive damages.
The Court of Appeal affirmed. We granted Genentech’s petition for review. Below, we discuss Genentech’s contentions.
II
A. Fiduciary Relationship
Genentech contends that no fiduciary relationship arose from its contract with City of Hope, thus requiring reversal of the jury’s award of punitive damages. We agree.
*386
“[B]efore a person can be charged with a fiduciary obligation, he must either knowingly undertake to act on behalf and for the benefit of another, or must enter into a relationship which imposes that undertaking as a matter of law.”
(Committee on Children’s Television, Inc.
v.
General Foods Corp.
(1983)
There is no indication in the contract that Genentech entered into it with the view of acting primarily for the benefit of City of Hope. Article 1 of the contract envisions a mutually beneficial relationship between the parties, as particularized in these provisions: Article 1.03 expresses Genentech’s desire to acquire from City of Hope synthetic DNA for the purpose of manufacturing and selling certain polypeptides. Article 1.04 states that City of Hope would receive funding from Genentech to conduct the DNA synthesis work and would earn royalties from Genentech’s sales. Article 3.04 gives Genentech exclusive ownership of patents and other proprietary property stemming from City of Hope’s work under the contract. And Article 10.01 gives Genentech the right to assign and transfer its contractual rights, including patents and patent licenses. These contractual provisions indicate that the parties’ common goal was to achieve a mutually beneficial arrangement, not that Genentech had undertaken a fiduciary obligation “to act on behalf of and for the benefit of another.”
(Children’s Television, supra,
Nor is there a factual basis showing that Genentech through its conduct “knowingly” undertook the obligations of a fiduciary.
(Children’s Television, supra,
The remaining question then is whether an agreement to develop, patent, and commercially exploit a secret scientific discovery in exchange for the payment of royalties is the type of relationship “which imposes that undertaking [fiduciary obligation to act on behalf of and for the benefit of another] as a matter of law.”
(Children’s Television, supra,
*387
At the request of City of Hope, the trial court instructed the jury that a “fiduciary relationship arises when a person entrusts a secret idea or device to another under an arrangement whereby the other party agrees to develop, patent and commercially exploit the idea in return for royalties.” The source of this jury instruction is a Court of Appeal decision,
Stevens
v.
Marco
(1956)
After reviewing the nature of the transaction between the parties, the Court of Appeal in
Stevens
concluded there was substantial evidence of a fiduciary relationship between the parties based on
the facts
presented.
(Stevens, supra,
City of Hope insists the trial court’s instruction based on
Stevens, supra,
City of Hope acknowledges that none of these four characteristics standing alone is determinative of the existence of a fiduciary relationship. We disagree with City of Hope’s contention, however, that whenever the relationship between the parties exhibits these four characteristics the relationship is necessarily fiduciary. (See Chodos, supra, § 1:19, p. 44 [futile to try to identify single set of factors that give rise to fiduciary relationship].)
For example, in
Children’s Television,
supra, 35 Cal.3d at pages 221-222, we refused to recognize a fiduciary relationship between commercial sellers and retail purchasers of breakfast cereals. It was there alleged that the sellers had superior bargaining power and better access to information, and that the sellers made representations and gave advice based on claimed expert knowledge in an effort to exploit the trust and uncritical acceptance of children who in turn induced their parents to buy the cereal. It could be said that there the purchasers entrusted the health of their children to the sellers (factor 1 of City of Hope’s test), who possessed the superior knowledge and expertise (factor 2), based on information not available to the children or their parents (factor 3), who were thus vulnerable and dependent on the sellers (factor 4). (See also
Persson v. Smart Inventions, Inc.
(2005)
Also, the four characteristics articulated by City of Hope and discussed above are common in many a contractual arrangement, yet do not necessarily give rise to a fiduciary relationship. For example, a person who takes a car to a garage for repairs has entrusted property to another (factor 1 of City of Hope’s test). Because the garage operator has expertise in the field of automotive repair but the car owner does not, the car owner must grant the garage operator broad discretion to carry out the necessary work (factor 2) and must rely on the truth of the garage operator’s representations about what repairs are needed and how they should be done (factor 3), leaving the car owner vulnerable and dependent on the garage operator (factor 4). Notwithstanding the presence of all these four factors, no court has ever held or suggested, as far as we know, that in this situation the garage operator owes *389 fiduciary duties to the car owner. A similar situation might be presented when a manufacturer entrusts its product to a retailer on consignment.
This case illustrates that, contrary to the above discussed overbroad language of the Court of Appeal in
Stevens, supra,
Was City of Hope vulnerable because it had to rely on Genentech’s superior ability in obtaining patents and in marketing products based on the secret scientific discovery of City of Hope scientists Drs. Riggs and Itakura? Yes, but not to the extent that would necessarily warrant recognition of a fiduciary duty. It is not at all unusual for a party to enter into a contract for the very purpose of obtaining the superior knowledge or expertise of the other party. Standing alone, that circumstance would not necessarily create fiduciary obligations, which generally come into play when one party’s vulnerability is so substantial as to give rise to equitable concerns underlying the protection afforded by the law governing fiduciaries. (See generally
Persson v. Smart Inventions, Inc., supra,
With respect to City of Hope’s claim that it reposed trust and confidence in Genentech, we note that “[e]very contract requires one party to repose an element of trust and confidence in the other to perform.”
(Wolf, supra,
Misplaced is City of Hope’s reliance on this court’s decisions in
Hollywood M. P. Equipment Co. v. Furer
(1940)
Schaake,
the other case relied on by City of Hope, involved an agreement under which an employee assigned to his corporate employer various patents for inventions, in return for which the employee retained an “indefeasible interest,” the equivalent of 25 percent, in the profits. In discussing the sufficiency of the pleadings, this court in passing observed that “[t]he relation thus created was fiduciary . . . .”
(Schaake, supra,
Thus, this court’s holdings in
Furer, supra,
Genentech cites the Court of Appeal’s decision in
Wolf, supra,
*391 After Disney developed and coproduced a highly successful motion picture entitled Who Framed Roger Rabbit, the plaintiff sued Disney for breach of contract and for breach of fiduciary duty, alleging that Disney had impaired his contractual audit right by refusing him access to Disney’s records. The trial court sustained Disney’s demurrer to the fiduciary duty cause of action. The Court of Appeal affirmed.
The Court of Appeal in Wolf concluded that a fiduciary duty did not arise simply from the plaintiff’s contractual right to receive compensation contingent upon the receipt of future revenues (contingent compensation), or from the profit-sharing provisions of the agreement, or from the plaintiff’s contractual right to an accounting, but that the profit-sharing provisions of the contract did shift the burden of proof to the defendant to prove compliance with the contractual payment obligations. (Wolf, supra, 107 Cal.App.4th at pp. 28-36.)
Wolf
reasoned that because every contract to some extent requires each party to repose trust and confidence in the other, one party’s right to contingent compensation, standing alone, does not give rise to a fiduciary duty.
(Wolf, supra,
We agree with the holding in
Wolf, supra,
Accordingly, we conclude that the trial court here erred in instructing the jury that a fiduciary relationship is necessarily created when a party, in return for royalties, entrusts a secret idea to another to develop, patent, and commercially develop.
2
Because fiduciary duties do not necessarily arise from this type of relationship, City of Hope’s only theory at trial for claiming a fiduciary relationship with Genentech was legally invalid, and therefore the judgment against Genentech is defective insofar as it is based on the jury’s finding that Genentech breached fiduciary duties owed to City of Hope. (See
Amelco Electric v. City of Thousand Oaks
(2002)
We now consider Genentech’s challenges to the judgment against it awarding compensatory damages for breach of contract.
B. Breach of Contract
City of Hope’s lawsuit against Genentech not only had a cause of action for breach of fiduciary duty but also one for breach of contract. City of Hope alleged that Genentech had breached the contract by failing to pay or report to City of Hope the full royalties due under the contract, and by failing to give City of Hope full access to Genentech’s records to accurately determine the full royalties owed. On this claim, the jury returned a verdict in favor of City of Hope. Genentech challenges that verdict on a number of grounds.
1. Claim that jury was prejudiced against Genentech by evidence admitted
Genentech argues that certain evidence admitted at trial on the issue of breach of fiduciary duty improperly influenced the jury in rendering a verdict against Genentech on City of Hope’s breach of contract claim. Although Genentech phrases its argument in terms of admission of evidence, it cites not *393 to the evidence admitted but to comments by opposing counsel during closing argument to the jury and to a jury instruction on the fiduciary duty to act in good faith and make full disclosure.
Genentech characterizes opposing counsel’s use of the word “concealment” at trial as inflammatory, and it complains that by linking issues of concealment, credibility, and contract, City of Hope successfully “leveraged” its “concealment evidence” to obtain a verdict against Genentech on the breach of contract claim. Genentech characterizes that “concealment evidence” as lacking probative value on the breach of contract claim, and it asserts that admission of that evidence prejudiced it because the trial was a “close case.”
Evidence that Genentech concealed from City of Hope information about a number of licenses that Genentech had issued to certain companies was admissible on the claim that Genentech had breached the contract by failing to fully report royalties owed to City of Hope and by denying it access to Genentech’s records to determine those royalties. As City of Hope points out, that evidence was relevant and admissible for three purposes: (1) to refute Genentech’s claim that City of Hope’s failure to challenge Genentech’s performance under the contract demonstrated that it agreed with Genentech’s interpretation of the contract; (2) to support City of Hope’s argument that the concealment showed that Genentech itself did not believe its asserted interpretation of the contract; and (3) to counter Genentech’s argument that City of Hope’s breach of contract claim was barred by the applicable statute of limitations because City of Hope should have known earlier of Genentech’s breach of contract. 3
A party’s conduct occurring between execution of the contract and a dispute about the meaning of the contract’s terms may reveal what the parties understood and intended those terms to mean. For this reason, evidence of such conduct, including concealment of certain information, is admissible to resolve ambiguities in the contract’s language.
(Oceanside 84, Ltd. v. Fidelity Federal Bank
(1997)
During closing argument, City of Hope’s counsel asked the jury that, in determining witness credibility, it consider the witnesses’ conflicting testimony about the meaning of key contract provisions; and counsel argued that determining witness credibility was important in deciding City of Hope’s claim for breach of contract. Genentech challenges the propriety of this argument. We perceive no impropriety. Genentech’s Tom Kiley and City of Hope’s John Hall, the attorneys who had negotiated the contract, gave widely divergent testimony about what the parties understood certain contractual provisions to mean. Deciding which of these two witnesses to believe was a credibility determination for the jury, which had the task of interpreting the contract. Nor are we persuaded by Genentech’s related claim that it was improper for City of Hope’s counsel to tell the jurors, during closing argument, that in resolving witness credibility issues they should consider the “big picture” and not get lost in the minutiae of the contractual language.
Genentech also challenges opposing counsel’s comment to the jury that it had to decide the breach of contract claim before resolving the breach of fiduciary duty claim. That comment was appropriate because it reflected what the verdict forms told the jury to do: to decide the breach of contract claim before the fiduciary duty claim.
Genentech complains about a jury instruction stating that fiduciary duties include acting in the utmost good faith and making full and fair disclosure of facts “which materially affect City of Hope’s rights and interests under the 1976 agreement.” Genentech appears to argue that the instruction improperly linked the contract claim to the fiduciary duty claim, so that a finding in City of Hope’s favor on one would necessarily require a finding for City of Hope on the other as well. Not so. The jury was also instructed that it was to decide City of Hope’s breach of contract claim separately from City of Hope’s breach of fiduciary duty claim. These instructions, which we presume the jury followed
(Cassim v. Allstate Ins. Co.
(2004)
*395 2. Genentech’s challenge to the general verdict
The jury returned a general verdict finding Genentech liable for, among other things, having breached the contract with City of Hope. Genentech contends interpretation of the contract was a question of law that should have been decided by the trial court, not the jury. Genentech argues the trial court should have asked the jury to make special findings on pertinent questions of fact, after which the court, taking into account the jury’s special findings, should have undertaken the task of interpreting the contract. We disagree.
Juries are not prohibited from interpreting contracts. Interpretation of a written instrument becomes solely a judicial function only when it is based on the words of the instrument alone, when there is no conflict in the extrinsic evidence, or when a determination was made based on incompetent evidence.
(Parsons v. Bristol Development Co.
(1965)
This rule—that the jury may interpret an agreement when construction turns on the credibility of extrinsic evidence—is well established in our case law. (See, e.g.,
Warner Constr. Corp. v. City of Los Angeles, supra,
In arguing to the contrary, Genentech relies on three Court of Appeal decisions:
De Guere
v.
Universal City Studios, Inc.
(1997)
In
Medical Operations, supra,
Casey, supra,
*397
With respect to
De Guere, supra,
We conclude that the trial court here did not err in having the jury resolve the breach of contract claim. 6
3. Jury instruction on resolving uncertainty in contract language
The trial court gave the jury a series of instructions on the rules governing contract interpretation. The last of these instructions stated: “If, after considering the evidence in light of the foregoing rules of interpretation, there remains an uncertainty in the language of the contract, that language must be interpreted against the party who caused the uncertainty to exist.” Genentech contends that the trial court erred in giving this jury instruction because the rule it states does not apply to contracts that are the result of negotiations, as was the contract between Genentech and City of Hope. Genentech relies on this statement from a 1962 Court of Appeal decision: “The contract. . . here is not like an insurance policy to be construed against one party. Rather, its terms were admittedly arrived at by negotiations between two parties.”
(Indenco, Inc. v. Evans
(1962)
Genentech reads too much into the quoted statement. Because “the insurer typically drafts policy language, leaving the insured little or no meaningful opportunity or ability to bargain for modifications,” ambiguities in policy provisions are generally resolved against the insurer and in favor of coverage.
(AIU Ins. Co.
v.
Superior Court
(1990)
The challenged jury instruction at issue here is taken almost verbatim from Civil Code section 1654, which provides: “In cases of uncertainty not removed by the preceding rules, the language of a contract should be *398 interpreted most strongly against the party who caused the uncertainty to exist.” The trial court’s instruction thus embodies a general rule of contract interpretation that was applicable to the negotiated agreement between Genentech and City of Hope. It may well be that in a particular situation the discussions and exchanges between the parties in the negotiation process may make it difficult or even impossible for the jury to determine which party caused a particular contractual ambiguity to exist, but this added complexity does not make the underlying rule irrelevant or inappropriate for a jury instruction. We conclude, accordingly, that the trial court here did not err in instructing the jury on Civil Code section 1654’s general rule of contract interpretation.
4. Admission of evidence of prior settlement
In 1995, before the lawsuit in this case was brought, Genentech and City of Hope settled a dispute concerning Genentech’s settlement of its lawsuit against Eli Lilly for patent infringement. At the trial in this case, the court allowed City of Hope to present evidence of its settlement with Genentech under which Genentech agreed to pay City of Hope royalties on Eli Lilly’s sales of products that did not use City of Hope’s synthesized DNA. Genentech contends this evidence should have been excluded under Evidence Code section 1152, subdivision (a), as evidence of a prior settlement. Genentech, however, stipulated to admission of this evidence. Therefore it is now barred from raising this claim.
Controlling here is the general rule that stipulations pertaining to the admission of evidence, absent an express limitation, apply to a later trial of the same action, unless the trial court allows the stipulation to be withdrawn.
(Gonzales v. Pacific Greyhound Lines
(1950)
Ill
The judgment of the Court of Appeal is reversed with directions that the Court of Appeal modify the trial court’s judgment to award City of Hope $300,164,030 as damages on its breach of contract claim, striking the award of punitive damages on its breach of fiduciary duty claim, and as so modified to affirm the judgment.
George, C. J., Baxter, J., Chin, J., Moreno, J., Corrigan, J., and Lambden, J., * concurred.
Notes
This judgment was entered after a second trial. The first trial ended in a mistrial when the jury deadlocked by a vote of seven to five in favor of Genentech.
Because we conclude that Genentech was not in a fiduciary relationship with City of Hope, we need not decide whether Genentech’s obtaining patents based on City of Hope’s scientific discovery could have terminated a fiduciary duty.
Our conclusion that the evidence was admissible makes it unnecessary for us to address City of Hope’s assertion that Genentech has forfeited appellate review of its claim pertaining to the admission of evidence of concealment because it did not object to the introduction of such evidence at trial, did not request a limiting instruction, did not ask the trial court to bifurcate trial of the contract cause of action from the trial of the fiduciary duty cause of action, and neither objected to City of Hope counsel’s comments during closing argument nor requested that the trial court give a curative admonition to the jury.
Inapposite here are the cases Genentech cites in support of its claim that the jury’s breach of contract verdict against it should be set aside. In
Fidler v. Hollywood Park Operating Co.
(1990)
Genentech relies on tort cases to support its assertion that the existence of a legal duty is always a question of law. (E.g.,
Merrill v. Navegar, Inc.
(2001)
This conclusion renders it unnecessary to address City of Hope’s assertion that because Genentech had proposed the general verdict form that the trial court provided to the jury, and did not request special findings by the jury, Genentech has forfeited its claim that special verdicts are required in contract cases.
