WINTER, Circuit Judge:

Thurman V. Whitfield, pro se, appeals from a grant of summary judgment. 582 F.Supp. 1186. His complaint invoked a variety of legal theories arising from defendants' alleged misappropriation of ideas contained in a television script he authored. Because we believe that the similarities between appellant's script and the appellees' television series can be appraised only by comparing the actual scripts, many of which are not in the record, we reverse and remand.

BACKGROUND

During the years 1975 through 1977, appellee Topper Carew worked on a proposed television series called "The Righteous Apples." On August 29, 1977, he filed a sixteen page registration with the Writers Guild consisting of a brief description of the series, descriptions of the characters, and marketing and production information. The document describes "The Righteous Apples" as a situation comedy involving a multiracial rock band of six junior high school students aged 13 through 15. A seventh student is the group's business manager. A primary theme of the series is the interaction of youths in a multiracial setting.

Carew was president of defendant Rainbow Television Workshop. On February 3, 1978, Rainbow entered into an agreement with the Corporation for Public Broadcasting ("CPB") to determine the feasibility of producing a pilot film based on "The Righteous Apples." On December 19, 1978, CPB agreed to provide funding to produce a pilot, which was filmed but never aired. The shooting script for the pilot, entitled "The Righteous Apple Wrangle," is in the record. That script is a situation comedy involving the characters described supra, and the plot essentially traces the resolution of racial tensions between one of the band members and another student. Another pilot script, with similar characteristics, is in the record.

During this period, appellant Whitfield was also working on a format for a television series and eventually he copyrighted a script for a show entitled "Boomerang." This was a dramatic show about an interracial, crime-fighting rock band, called Boomerang. The band had five members, two white, one Spanish-surnamed, and two black. All five were recent graduates of the same high school where they had formed the band. In the "Boomerang" script, which is also in the record, the band members fight crime using their athletic talents and occasionally a boomerang as a weapon.

Following the copyrighting of "Boomerang," Whitfield added additional scenes to the script and circulated it to television producers. In March, 1979, he sent a mailgram to the defendant Norman Lear and his company, Tandem Productions, informing them that a script was forthcoming. Lear forwarded the mailgram to another company he controlled, defendant TAT Communications, and so informed Whitfield. In 1980-1981, a twenty-episode series entitled "The Righteous Apples," produced by Carew, was broadcast under CPB auspices. Whitfield contends that "The Righteous Apples" series differs from the original pilot script and that the series as actually broadcast bears a strong resemblance to "Boomerang," resulting from Carew's access to the latter script through Tandem Productions and his appropriation of the ideas contained therein.

On June 4, 1981, appellant commenced this action alleging federal and state claims and diversity of citizenship. His complaint alleged the following causes of action under California law:

(1) Breach of contract;

(2) Breach of confidential or fiduciary relationship;

(3) Breach of implied covenant of good faith and fair dealing;

(4) Fraud and misrepresentation;

(5) Misappropriation and commercial piracy;

(6) Unfair competition;

(7) False designation of origin and false advertising;

(8) Restitution based on quasi-contract and unjust enrichment.

He also alleged copyright infringement under 17 U.S.C. § 501 and a violation of the Lanham Act, 15 U.S.C. §§ 1051-1127. Appellees moved for summary judgment, and both parties submitted affidavits. Appellees conceded access to Whitfield's script, and, apparently, their group involvement for Carew's series, solely for purposes of the motion. Judge Glasser granted the motion. The appellant, who was represented in the district court by counsel, prosecuted this appeal pro se.

DISCUSSION

Appellant has never alleged that the appellees actually copied from his script, only that they misappropriated ideas contained therein. Such a claim does not implicate the federal copyright laws, and appellant withdrew his copyright and Lanham Act claims in the district court. He thus now relies solely on a variety of causes of action under California law.

Appellant claims an interest in the ideas contained in his script and seeks redress for misappropriation of the ideas, not their literary or artistic expression. This theory narrows the legal grounds available for recovery even further. Under California law, the fraud, misappropriation, unfair competition, and quasi-contract claims are actionable only to vindicate legally protected property interests, and an idea is not recognized as a property right. Weitzenkorn v. Lesser, 40 Cal.2d 778, 789, 256 P.2d 947, 956 (1953) (en banc). Recovery for the appropriation of an idea, therefore, may be had only on a contractual theory. See Donahue v. Ziv Television Programs, Inc., 245 Cal.App.2d 593, 601, 54 Cal.Rptr. 130, 137 (1966).

While an idea is not property and is not subject to copyright under California law, its disclosure may be valid consideration for a contract. There is no evidence of an express contract between Whitfield and any of the defendants. However, California law will imply a contract from the conduct of the parties in certain circumstances. Thus, if a producer accepts a submitted idea with full knowledge that the offeror expects payment in the event of use, California courts impose liability under a theory of implied-in-fact contract. Desny v. Wilder, 46 Cal.2d 715, 299 P.2d 257 (1956) (en banc). In that case, the plaintiff called Wilder, a writer/producer for Paramount Pictures Corp. and, when asked the purpose of his call by Wilder's secretary, told her of an idea he had for a motion picture. At the secretary's invitation, the plaintiff dictated a brief synopsis of his idea over the telephone. Following this disclosure, the plaintiff stated that he expected to be paid if the idea were used, and the secretary acknowledged that he would be. The California Supreme Court held these facts sufficient to survive defendant's motion for summary judgment in a suit alleging that the defendants had used the idea without payment. The court also set forth the circumstances in which a contract might be implied absent an express promise to pay:

[T]he idea purveyor cannot prevail in an action to recover compensation for an abstract idea unless (a) before or after disclosure he has obtained an express promise to pay, or (b) the circumstances preceding and attending disclosure, together with the conduct of the offeree acting with knowledge of the circumstances, show a promise of the type usually referred to as "implied" or "implied-in-fact."

Id. at 738, 299 P.2d at 270 (footnote and citations omitted). California courts still follow the Wilder test. See Klekas v. EMI Films, Inc., 150 Cal.App.3d 1102, 1114, 198 Cal.Rptr. 296, 304 (1984).

Appellees argue that, even accepting Whitfield's version of the facts surrounding submission of "Boomerang," there is insufficient evidence to support an implied contract. They rely upon the statement in Wilder that:

The law will not imply a promise to pay for an idea from the mere facts that the idea has been conveyed, is valuable, and has been used for profit; this is true even though the conveyance has been made with the hope or expectation that some obligation will ensue.

46 Cal.2d at 739, 299 P.2d at 270.

In the instant case, Whitfield sent a mailgram to Lear and Tandem Productions informing them that a script was forthcoming and then sent the "Boomerang" script. An assistant to Lear wrote to Whitfield stating that, although Lear was not personally interested in "Boomerang," the mailgram had been forwarded to the Senior Vice President for Creative Affairs at TAT Communications. The parties had no further communications.

Whitfield contends that the custom in the television industry is that a studio or producer not desiring any outside submissions states so explicitly and, when a studio or producer is not interested in reviewing a particular script, the script is returned unopened. If, however, a studio or producer is notified that a script is forthcoming and opens and reviews it when it arrives, that studio or producer has by custom implicitly promised to pay for the ideas if used. See M. Nimmer, Nimmer on Copyright § 16.05[c] (1984) (if recipient has advance warning of and opportunity to reject disclosure, and knows that person submitting expects payment, California law will infer promise to pay in the event of use).

We conclude that the communications in question and the allegation of custom in the industry are sufficient to withstand a motion for summary judgment on this point. In Minniear v. Tors, 266 Cal.App.2d 495, 72 Cal.Rptr. 287 (1968), the plaintiff produced a pilot film and permitted a television director to view it at the latter's request. The parties engaged in no negotiations. The director's company later produced an arguably similar television series. Based on the plaintiff's claim that "it is understood in the industry that when a showing is made, the offeror shall be paid for any ideas or materials used therein," id. at 500, 72 Cal.Rptr. at 291, the court held that a jury could infer that the defendant accepted the ideas with the knowledge that plaintiff expected payment.

The facts of the instant case are similar to Minniear. The correspondence between the parties, brief as it was, has some of the attributes of bargaining. Whitfield's mailgram described his experience as a radio broadcaster and his knowledge of the entertainment market. These statements were obviously designed to persuade the recipient to open the script and give it careful scrutiny. The letter from Lear's assistant stated that the Vice President for Creative Affairs at TAT Communications would contact him "should we be interested in accepting new material from writers outside of our organization." This is arguably an acknowledgment that Whitfield's ideas were not freely appropriable. If, as appellees argue, they were perfectly free to use Whitfield's ideas without compensation as soon as they received them, there was nothing to "accept," and no further communication with Whitfield was necessary. On the whole, the record raises a material issue of fact as to whether the appellees accepted Whitfield's submission on an understanding common in the industry that he expected payment if the ideas were used.

The appellant has a second hurdle to clear. To support recovery on an implied-in-fact contract, he must show not only access but also that the appellees actually used his ideas by demonstrating "some substantial similarity" between the ideas and themes of the two programs. Kurlan v. Columbia Broadcasting System, 40 Cal.2d 799, 809, 256 P.2d 962, 969 (1953). Access having been conceded for purposes of the motion for summary judgment, the district court concluded that "there are no similarities between the ideas contained in defendant's production and plaintiff's work." Mem. at 9 (emphasis in original).

We are unable to verify this conclusion. The scripts of the actual episodes of "The Righteous Apples" that appeared on television are not in the record and were not reviewed by the district court. The only "Righteous Apples" scripts in the record are pilots prepared before appellant's submission of "Boomerang" to Lear. However, the essence of Whitfield's claim is that "The Righteous Apples" as televised differed significantly from the appellees' original pilots.

Since no scripts of the actually televised series are in the record, the critical comparison can be made only on the basis of other materials submitted by the parties. However, these materials are in utter conflict over the existence of similarities between the televised series and the "Boomerang" script. Appellees thus describe the first ten televised episodes of "The Righteous Apples" in a manner wholly at odds with Whitfield's description of similarities between those episodes and his "Boomerang" script.

Assuming access by the defendants to the "Boomerang" script and accepting Whitfield's assertions regarding the content of the televised series as true, as we must on a motion for summary judgment, we conclude that the alleged similarities between the "Righteous Apples" series and "Boomerang," viewed in light of the earlier pilot scripts, are sufficient to allow a trier of fact to find that Whitfield's ideas were misappropriated under California law. There is thus dispute over material facts which can be resolved only by comparing the pilot scripts (in the record) prepared before the submission of "Boomerang," the Boomerang script (in the record), with "The Righteous Apples" scripts actually used in the televised series (not in the record). There were, therefore, insufficient grounds to grant summary judgment.

Reversed and remanded for further proceedings.
