Anthony James Frybarger appeals from a summary judgment in favor of IBM Cor *527 poration, Inc., Nasir Gebelli, and Gebelli Software, Inc. (“Gebelli”), in his copyright infringement and Lanham Act action. Frybarger claims that Gebelli copied protected elements of Frybarger’s “TRICKY TRAPPER” drawings, computer program and videogame, in Gebelli’s “MOUSER” storyboard, computer program and videogame, which Gebelli licensed to IBM for use with its PC Jr. personal computer. Frybarger brought an action in United States District Court for the Eastern District of California, alleging federal causes of action for copyright infringement under 17 U.S.C. §§ 101-810 (1982), and unfair competition under the Lanham Act, 15 U.S.C. §§ 1051-1127 (1982), as well as pendent state law claims for misappropriation of trade secrets, unfair competition, conversion and unjust enrichment. The district court granted IBM’s motion for summary judgment on the federal causes of action concluding, as a matter of law, that no reasonable jury could find Gebelli’s works substantially similar to Frybarger’s works. The district court then dismissed Frybarger’s state law claims without prejudice.
Frybarger only appeals the summary judgment on his federal causes of action. This court has jurisdiction under 28 U.S.C. § 1291. We affirm.
FACTS
Frybarger was employed by Gebelli in 1982. During the Summer of 1982, Frybarger submitted design drawings and a flow chart describing his “TRICKY TRAPPER” videogame to Gebelli pursuant to a confidential disclosure agreement. In addition, Frybarger had several conversations with Nasir Gebelli and Gebelli employees regarding his “TRICKY TRAPPER” video-game and provided, at Gebelli’s request, an annotated computer program and a playable disk of “TRICKY TRAPPER” in September and November 1982.
During the period of Frybarger’s employment, Gebelli had a consulting agreement with IBM regarding the development of electronic videogame programming for the IBM personal computer. On October 19, 1982, Gebelli entered into an agreement with IBM to develop three videogames for the IBM PC Jr. personal computer and submitted storyboards to IBM on November 19, 1982, for two of the proposed video-games. One of the two storyboards was for Gebelli’s “MOUSER” videogame. Soon thereafter, Gebelli finished the “MOUSER” electronic videogame, registered the copyrights in it, and IBM began to market and' distribute it.
In 1984, Frybarger registered the copyrights in his “TRICKY TRAPPER” video-game. On July 13, 1984, Frybarger filed his first complaint and, on September 24, 1985, an amended complaint, against IBM, Gebelli, and Nasir Gebelli, in United States District Court for the Eastern District of California. In his amended complaint, Frybarger alleged that Gebelli infringed Frybarger’s copyrights by using elements of Frybarger’s “TRICKY TRAPPER” works in Gebelli’s “MOUSER” works, and that Gebelli’s infringement constituted unfair competition under Section 43(a) of the Lanham Act, 15 U.S.C. § 1125(a). Frybarger also alleged pendent state law claims for misappropriation of trade secrets, unfair competition, conversion, and unjust enrichment. Shortly thereafter, IBM submitted motions for summary judgment and judgment on the pleadings.
On February 10, 1986, the district court held a three and one-half hour hearing on IBM’s motions for summary judgment and judgment on the pleadings. At the hearing, the district court viewed “MOUSER” in play on an IBM PC Jr. computer, “TRICKY TRAPPER” in play on an Apple II computer and on videotape, and four other videogames. 1 The court also examined six color photographs, prepared by IBM, comparing key elements of Frybarger’s and Gebelli’s videogames, and several affidavits from videogame, programming, and software experts submitted by eách side. At the close of the hearing, the court granted IBM’s motion for summary judgment on the copyright infringement and Lanham Act causes of action, concluding, *528 as a matter of law, that no reasonable jury could find Frybarger’s and Gebelli’s works substantially similar. The court then dismissed Frybarger’s state law claims without prejudice. The district court’s decision was made applicable to Gebelli and Nasir Gebelli by stipulation of the parties, and judgment was entered on April 11, 1986. Frybarger timely appealed.
DISCUSSION
Summary judgments in copyright infringement cases are subject to de novo review by this court.
Berkic v. Crichton,
I. SUMMARY JUDGMENT
Generally, “summary judgment is not highly favored on the substantial similarity issue in copyright cases.”
Berkic,
Summary judgment is clearly appropriate in copyright infringement cases if, after viewing the evidence and drawing every inference in the light most favorable to the nonmoving party, the court concludes that no reasonable jury could find substantial similarity of both ideas and expression between the works at issue.
Litchfield,
Because plaintiff bears the burden of proving that the works at issue are substantially similar in a copyright infringement case,
Litchfield,
II. COPYRIGHT INFRINGEMENT
To establish a claim for copyright infringement, plaintiff must show that 1) she owns the copyright in the allegedly copied work; 2) defendant had access to the work; and 3) plaintiff’s and defendant’s works are substantially similiar.
Cooling Sys. and Flexibles, Inc. v. Stuart Radiator, Inc., 777
F.2d 485, 491 (9th Cir.1985) (citing
Berkic,
Although plaintiff must show that the ideas in the works at issue are substantially similar, the ideas themselves are not protected by copyright and cannot, therefore, be infringed.
See Harper & Row Publishers, Inc. v. Nation Enters.,
Those features of Frybarger's works that are ideas are not protected, therefore, against even directly copied identical ideas in Gebelli's works. Thus, to the extent that the similarities between Frybarger’s and Gebelli’s works are confined to ideas and general concepts, these similarities are noninfringing. See 3 M. Nimmer, Nimmer On Copyright § 13.03[A][1] at 13-21 (1986) (“[I]f the only similarity between plaintiff’s and defendant’s works is that of the abstract idea, there is an absence of substantial similarity and hence no infringement results.”) (emphasis in original).
The district court concluded that the only similar features in Frybarger’s and Gebelli’s works are nonprotectible ideas. As for the expressive elements in the works, the district court held that no reasonable jury could find them substantially similar. After viewing Frybarger’s and Gebelli’s works, and the other videogames viewed by the district court, we are convinced that the district court was correct. Although there are numerous similar features in Frybarger’s and Gebelli’s works,

*530
we believe that each of the similar features constitutes a basic idea of the videogames and, to the extent each feature is expressive, that the expression is “ ‘as a practical matter indispensable, or at least standard, in the treatment of a given [idea].’ ”

Atari, Inc. v. North American Philips Consumer Elecs. Corp.,
Furthermore, the mere
indispensable
expression of these ideas, based on the technical requirements of the videogame medium, may be protected only against virtually identical copying.
Atari,
For the reasons above, there could be no copyright infringement as a matter of law. Therefore, the district court properly granted summary judgment.
AFFIRMED.
Notes
. “LADY BUG”, "MOUSETRAP”, "LOCK n' CHASE" and "DRELBS”.
. “TRICKY TRAPPER” and "MOUSER" share the following similar features:
1) The display screen of each game is filled with straight rows of pivot points on a solid colored background.
2) Between some of the pivot points are solid lines, connecting two pivot points.
3) There is a single protagonist.
4) The single protagonist has legs and a face.
*530 5) The single protagonist moves vertically and horizontally between rows of pivot points.
6) The single protagonist may cause one end of a line to come unattached from one pivot point and attach to a different pivot point by bumping into the line as the protagonist moves between rows of pivot points.
7) There is more than one antagonist.
8) Each antagonist moves toward the general location of the protagonist.
9) If an antagonist bumps into the protagonist, the progress of play stops.
10) An antagonist will be immobilized if it is surrounded on three sides by lines and the protagonist bumps a line across the fourth side, closing off the only remaining avenue of exit.
11) The player may obtain points by causing the protagonist to elude and 'trap' antagonists.
12) . The speed at which the protagonist and antagonists move increases as the game progresses.
. This is the
scenes a faire
doctrine, applied in infringement cases to " ‘expression ... which necessarily results from the fact that the common idea is only capable of expression in more or less stereotyped form.’ ”
