Lisa and Macintosh are Apple computers. Each has a graphical user interface (“GUI”) which Apple Computer, Inc. registered for copyright as an audiovisual work. Both GUIs were developed as a user-friendly way for ordinary mortals to communicate with the Apple computer; the Lisa Desktop and the Macintosh Finder 1 are based on a desktop metaphor with windows, icons and pull-down menus which can be manipulated on the screen with a hand-held device called a mouse. When Microsoft Corporation released Windows 1.0, having a similar GUI, Apple complained. As a result, the two agreed to a license giving Microsoft the right to use and sublicense derivative works generated by Windows 1.0 in present and future products. Microsoft released Windows 2.03 and later, Windows 3.0; its licensee, Hewlett-Packard Company (HP), introduced NewWave 1.0 and later, NewWave 3.0, which run in conjunction with Windows to make IBM-compatible computers easier to use. Apple believed that these versions exceed the license, make Windows more “Mac-like,” and infringe its copyright. This action followed.
In a series of published rulings, 2 the district court construed the agreement to license visual displays in the Windows 1.0 interface, not the interface itself; determined that all visual displays in Windows 2.03 and 3.0 were in Windows 1.0 except for the use of overlapping windows 3 and some changes in the appearance and manipulation of icons; dissected the Macintosh, Windows and New-Wave interfaces based on a list of similarities submitted by Apple to decide which are pro-tectable; and applied the limiting doctrines of originality, functionality, standardization, scenes afaire and merger to find no copying of protectable elements in Windows 2.03 or 3.0, and to limit the scope of copyright protection to a handful of individual elements in NewWave. 4 The court then held that those elements in NewWave would be compared with their equivalent Apple elements for substantial similarity, and that the NewWave and Windows 2.03 and 3.0 works as a whole would be compared with Apple’s works for virtual identity. When Apple declined to oppose motions for summary judgment of noninfiingement for lack of virtual identity, however, judgments in favor of Microsoft and HP were entered.
Apple asks us to reverse because of two fundamental errors in the district court’s reasoning. 5 First, Apple argues that the court *1439 should not have allowed the license for Windows 1.0 to serve as a partial defense. Second, Apple contends that the court went astray by dissecting Apple’s works so as to eliminate unproteetable and licensed elements from comparison with Windows 2.08, 3.0 and NewWave as a whole, incorrectly leading it to adopt a standard of virtual identity instead of substantial similarity. We disagree.
The district court’s approach was on target. In so holding, we readily acknowledge how much more complex and difficult its task was than ours. The district court had to grapple with graphical user interfaces in the first instance — and for the first time, with a claim of copying a computer program’s artistic look as an audiovisual work instead of program codes registered as a literary work. In this case there is also the unusual, added complexity of a license that arguably covers some or most of the allegedly infringing works. The district court therefore had to cut new paths as it went along; we have the luxury of looking at the case at the end of the trip. From this vantage point, it is clear that treatment of Apple’s GUIs, whose visual displays are licensed to a great degree and which are a tool for the user to access various functions of a computer in an aesthetically and ergonomically pleasing way, follows naturally from a long line of copyright decisions which recognizes that works cannot be substantially similar where analytic dissection demonstrates that similarities in expression are either authorized, or arise from the use of common ideas or their logical extensions.
We therefore hold:
(1)Because there was an agreement by which Apple licensed the right to make certain derivative works, the district court properly started with the license to determine what Microsoft was permitted to copy. Infringement cannot be founded on a licensed similarity. We read Microsoft’s license as the district court did, to cover visual displays — not the Windows 1.0 interface itself. That being so, the court correctly decided first to identify which visual displays in Windows 2.03, 3.0 and NewWave are licensed and which are not.
(2) The district court then properly proceeded to distinguish ideas from expression, and to “dissect” unlicensed elements in order to determine whether the remaining similarities lack originality, flow naturally from basic ideas, or are one of the few ways in which a particular idea can be expressed given the constraints of the computer environment. Dissection is not inappropriate even though GUIs are thought of as the “look and feel” of a computer, because copyright protection extends only to protectable elements of expression.
(3) Having found that the similarities in Windows 2.03 and 3.0 consist only of unpro-tectable or licensed elements, and that the similarities between protectable elements in Apple’s works and NewWave are de minim-is, 6 the district court did not err by concluding that, to the extent there is creative expression left in how the works are put together, as a whole they can receive only limited protection. When the range of pro-tectable and unauthorized expression is narrow, the appropriate standard for illicit copying is virtual identity. For these reasons, the GUIs in Windows 2.03, 3.0 and NewWave cannot be compared for substantial similarity with the Macintosh interface as a whole. Instead, as the district court held, the works must be compared for virtual identity. 7
*1440 Apple also challenges dismissal of the Macintosh Finder as a work in suit. Although we agree that the Finder, which is registered as a derivative work of the Lisa Desktop, should not have been dismissed as a work in suit because the underlying copyright on the Lisa has not expired, Apple’s non-opposition to judgment as to the Lisa applies to the Finder as well. The Macintosh Finder is not incrementally different from the Lisa Desktop in any respect material to Apple’s claims of infringement. There is accordingly no basis in the record for reversal on account of the erroneous dismissal of the Finder.
Finally, Microsoft and HP cross-appeal denial of their requests for attorney’s fees. Since the district court’s decision, the Supreme Court has conferred greater discretion to award fees to prevailing defendants than our law previously acknowledged.
Fogerty v. Fantasy, Inc.,
— U.S. —,
I
Analysis of Apple’s infringement claims must start with an agreement signed in 1985 by Apple and Microsoft, which resolved a dispute about visual displays generated by Microsoft software products. The 1985 Agreement licensed the right to use the visual displays generated by Apple’s Lisa and Macintosh graphic user interface programs which appeared as derivative works in Windows l.O. 8 As a result, to the extent that later versions of Windows and NewWave use the visual displays in Windows 1.0 (which came from Apple), that use is authorized.
Apple’s appeal turns on whether the Agreement, properly construed, gives Microsoft the right to transfer individual elements or design features used in Windows 1.0. Apple particularly objects to any interpretation that would permit later Windows products to look more like the Macintosh than Windows 1.0 looked.
The plain language of the Agreement disposes of Apple’s argument. It licenses Microsoft to use “these derivative works.” “These derivative works” can only refer to Microsoft’s acknowledgment that the “visual displays” generated by Windows 1.0 “are derivative works of the visual displays generated by Apple’s Lisa and Macintosh graphic user interface programs.” As the district court explained:
Had it been the parties’ intent to limit the license to the Windows 1.0 interface, they would have known how to say so. Instead, the “derivative works” covered by the license are identified as the “visual displays” in the Windows 1.0 interface, not the interface itself. And there is nothing in the 1985 Agreement that indicates that it was intended as a product license restricting Microsoft and its licensees to the use of the Windows 1.0 interface as a whole.
Apple II, 111 F.Supp. at 1430-31.
Apple contends that the term “visual displays” is ambiguous and can reasonably be construed (against Microsoft, as drafter) to distinguish audiovisual copyrights protecting visual works from literary copyrights protecting programs, and to cover use of so much of Apple’s visual copyrights as were used in Windows 1.0 but no more. This argument fails because Apple tried to limit Microsoft’s license to Windows 1.0 as a whole — but did not succeed. Apple’s first draft included language providing that “at no time shall this grant extend to any appearance, look, feel, visual feature or operation other than that incorporated in Microsoft Windows.” Microsoft, however, rejected this limitation. Thus, the parties had already *1441 staked out their positions by the time Microsoft produced the final draft. Accordingly, there is no basis for construing the Agreement to grant the narrow license Apple bargained for but gave up.
Apple relies on statements by various Microsoft employees in support of its ambiguity argument. These are unavailing because the Agreement has an integration clause which precludes contradicting its terms by collateral understandings.
Hayter Trucking, Inc. v. Shell Western E & P, Inc.,
Apple’s further contention that the district court’s interpretation of the Agreement must be wrong because it would be unreasonable to suppose that Apple knowingly gave away its most valuable technological asset ignores the fact that Apple itself received valuable consideration under the Agreement: the right to use and license any new displays created by Microsoft within five years, together with Microsoft’s promises to delay release of an IBM-compatible version of Excel and to release an improved version of Microsoft Word for the Macintosh. Under these circumstances, the district court properly concluded that the Agreement is not reasonably susceptible to Apple’s interpretation. 9
II
Apple also appeals denial of its own motion for partial summary judgment that the works, viewed overall as they are viewed by users, are unlicensed derivative works substantially similar to Apple’s works. Our resolution of its argument for reversal of judgments in favor of Microsoft and HP essentially disposes of this issue.
Apple raises one additional point, however, which we address here because Apple treats it as connected to its motion. The argument is that even if the 1985 Agreement does confer a partial license to use visual displays, Microsoft and HP exceeded its scope and therefore infringed Apple’s copyrights.
See, e.g., S.O.S., Inc. v. Payday, Inc.,
Ill
Apple makes a number of related arguments challenging the district court’s copyright analysis. It contends that the district court deprived its works of meaningful protection by dissecting them into individual elements and viewing each element in isolation. Because the Macintosh GUI is a dynamic audiovisual work, Apple argues that the “total concept and feel” of its works — that is, the selection and arrangement of related images and their animation — must be compared with that of the Windows and NewWave GUIs for substantial similarity. Apple further asserts that in this case, the court had no occasion to dissect its works into discrete elements because Microsoft and HP virtually mimicked the composition, organization, arrangement and dynamics of the Macintosh interface, as shown by striking similarities in the animation of overlapping windows and the design, layout and animation of icons. Apple also argues that even if dissection were appropriate, the district court should not have eliminated from jury consideration those elements that are either licensed or unprotected by copyright. Though stated somewhat differently, all of these contentions boil down to the same thing: Apple wants an overall comparison of its works to the accused works for substantial similarity rather than virtual identity. 10
The fact that Apple licensed the right to copy almost all of its visual displays fundamentally affects the outcome of its infringement claims. Authorized copying accounts for more than 90% of the allegedly infringing features in Windows 2.03 and 3.0, and two-thirds of the features in NewWave. More than that, the 1985 Agreement and negotiations leading up to Microsoft’s license left Apple no right to complain that selection and arrangement of licensed elements make the interface as a whole look more “Mac-like” than Windows 1.0.
Thus, we do not start at ground zero in resolving Apple’s claims of infringement. Rather, considering the license and the limited number of ways that the basic ideas of the Apple GUI can be expressed differently, we conclude that only “thin” protection, against virtually identical copying, is appropriate. Apple’s appeal, which depends on comparing its interface as a whole for substantial similarity, must therefore fad.
To prevail, Apple must show ownership of a valid copyright in the Macintosh GUI and that Microsoft and HP copied unlicensed, protected elements of its copyrighted audiovisual works.
Brown Bag Software v. Symantec Corp.,
We have traditionally determined whether copying sufficient to constitute infringement has taken place under a two-part test having “extrinsic” and “intrinsic” components. As originally adopted in
Sid & Marty Krofft Television Productions, Inc. v. McDonald’s Corp.,
Although this litigation has raised difficult and interesting issues about the scope of copyright protection for á graphical user interface, resolving this appeal is a matter of applying well-settled principles. In this, as in qther cases, the steps we find helpful to follow are these:
(1) The plaintiff must identify the source(s) of the alleged similarity between his work and the defendant’s work.
(2) Using analytic dissection, and, if necessary, expert testimony, the court must determine whether any of the allegedly similar features are protected by copyright. Where, as in this case, a license agreement is involved, the court must also determine which features the defendant was authorized to copy. Once the scope of the license is determined, unprotectable ideas must be separated from potentially protectable expression; to that expression, the court must then apply the relevant limiting doctrines in the context of the particular medium involved, through the eyes of the ordinary consumer of that product.
(3) Having dissected the alleged similarities and considered the range of possible expression, the court must define the scope of the plaintiffs copyright — that is, decide whether the work is entitled to “broad” or “thin” protection. Depending on the degree of protection, the court must set the appropriate standard for a subjective comparison of the works to determine whether, as a whole, they are sufficiently similar to support a finding of illicit copying.
A
Like the plaintiff in Brown Bag, in this ease, Apple identified the sources of alleged similarity by submitting a list of particular features in its works which are similar to features found in Windows 2.03, 3.0 and NewWave. Apple’s suggestion that its arm was twisted to provide this list of similarities and that it was somehow inappropriate for the district court to ask for a list and to rely on it, instead of considering the works as a whole, is misplaced. The court had the benefit of numerous videotapes and demonstrations of the GUIs “as a whole.” The district court was nevertheless obliged to identify similarities, determine their source, and decide which elements are protectable. It was thus well within the court’s case management discretion to ask for a list from Apple.
B
It is not easy to distinguish expression from ideas, particularly in a new medium. However, it must be done, as the district court did in this case.
Baker v. Selden,
The district court found that there are five other basic ideas embodied in the desktop metaphor: use of windows to display multiple images on the computer screen and
*1444
to facilitate user interaction with the information contained in the windows; iconic representation of familiar objects from the office environment; manipulation of icons to convey instructions and to control operation of the computer; use of menus to store information or computer functions in a place that is convenient to reach, but saves screen space for other images; and opening and closing of objects as a means of retrieving, transferring and storing information.
Apple V,
Well-recognized precepts guide the process of analytic dissection. First, when an idea and its expression are indistinguishable, or “merged,” the expression will only be protected against nearly identical copying.
Kroffi,
The doctrine of
scenes a faire
is closely related. As we explained in
Frybar-ger v. International Business Machines Corp.,
Apple suggests that
scenes a faire
should not limit the scope of its audiovisual copyright, or at least that the interactive character of GUIs and their functional purpose should not outweigh their artistry. While user participation may not negate copyrightability of an audiovisual work,
see, e.g., Midway Mfg. Co. v. Artic Int’l, Inc.,
To the extent that GUIs are artistic, there is no dispute that creativity in user interfaces is constrained by the power and speed of the
*1445
computer.
See Manufacturers Technologies, Inc. v. Cams, Inc.,
Originality is another doctrine which limits the scope of protection. As the Supreme Court recently made clear, protection extends only to those components of a work that are original to the author, although original selection and arrangement of otherwise uncopyrightable components may be protect-able.
Feist Publications, Inc. v. Rural Tel. Serv. Co.,
In sum, the district court’s analytic dissection was appropriately conducted under the extrinsic portion of our test for whether sufficient copying to constitute infringement has taken place. We are not persuaded to the contrary by Apple’s arguments that the district court shouldn’t have dissected at all, or dissected too much; that it “filtered out” unprotectable and licensed elements instead of viewing the Macintosh interface as a whole; and that it should have recognized protectability of arrangements and the “total concept and feel” of the works under a substantial similarity standard.
First, graphical user interface audiovisual works are subject to the same process of analytical dissection as are other works. We have dissected videogames, which are audiovisual works and therefore closely analogous,
see, e.g., Data East,
Nor did the district court’s dissection run afoul of the enjoinder in such cases as
Johnson Controls,
As we made clear in
Aliotti,
the party claiming infringement may place
“no
reliance upon any similarity in expression resulting from” unprotectable elements.
Id.
(emphasis added) (similarities between competing stuffed dinosaur toys on account of posture and body design, and being cuddly, stem from the physiognomy of dinosaurs or from the nature of stuffed animals and are thus unprotectable). Otherwise, there would be no point to the extrinsic test, or to distinguishing ideas from expression. In this case, it would also effectively rescind the 1985 Agreement. This does not mean that at the end of the day, when the works are considered under the intrinsic test, they should not be compared as a whole.
See McCulloch v. Albert E. Price, Inc.,
C
The district court’s conclusion that the works as a whole are entitled only to limited protection and should be compared for virtual identity follows from its analytic dissection. By virtue of the licensing agreement, Microsoft and HP were entitled to use the vast majority of features that Apple claims were copied. Of those that remain, the district court found no unauthorized, protectable similarities of expression in Windows 2.03 and 3.0, and only a handful in NewWave. Thus, any claim of infringement that Apple may have against Microsoft must rest on the copying of Apple’s unique selection and arrangement of all of these features. Under Harper House and Frybarger, there can be no infringement unless the works are virtually identical.
Apple, however, contends that its audiovisual work with animation and icon design cannot be analogized to factual works such as game strategy books,
see Landsberg v. Scrabble Crossword Game Players, Inc.,
Which end of the continuum a particular work falls on is a call that must be made case by case. We are satisfied that this ease is closer to
Frybarger
than to
McCulloch. See also Atari Games Corp. v. Oman,
Apple also argues that the district court improperly confined the rule in
Shaw,
We therefore hold that the district court properly identified the sources of similarity in Windows and NewWave, determined which were licensed, distinguished ideas from expression, and decided the scope of Apple’s copyright by dissecting the unauthorized expression and filtering out unprotectable elements. Having correctly found that almost all the similarities spring either from the license or from basic ideas and their obvious expression, it correctly concluded that illicit copying could occur only if the works as a whole are virtually identical.
IV
Apple contends that the district court erred in dismissing the Macintosh Finder as a work in suit. Based on 17 U.S.C. § 103(b), which provides that “[t]he copyright in a ... derivative work extends only to the material contributed by the author of such work, as distinguished from the preexisting material employed in the work,” the court concluded that Apple could not proceed on the Finder because the Finder is a derivative work of the original Lisa Desktop and all of the unlicensed similarities are covered by the underlying Lisa copyrights.
We agree with Apple that the district court’s reading of § 103(b) is too restrictive. Although it relied on
Silverman v. CBS Inc.,
In this ease, however, Apple is the author and copyright owner of the Lisa Desktop
and
the Macintosh Finder, both of which are still protected. Apple argues that under these circumstances, § 103(b) does not prevent it from claiming infringement of the Finder, even for copied material that was incorporated from the Lisa.
See, e.g., E.F. Johnson Co. v. Uniden Corp. of Am.,
Because Apple owns the copyrights in both works, it is similarly situated to an exclusive licensee. If the copyright owner of a derivative work is the
exclusive
licensee of certain rights in the underlying work, he is treated as the copyright owner of the underlying work for' the purpose of exercising those rights. 1 Melville B. Nimmer & David Nimmer,
Nimmer on Copyright
§ 3.05, at 3-
*1448
32.2 (1993). He can therefore sue for copying of material that appears in both the derivative work and the underlying work.
Id.; see Gamma Audio & Video, Inc., v. Ean-Chea,
Nevertheless, we need not reverse. Apple contends that it was deprived of the opportunity fairly to present its case because the Finder is what everyone is familiar with and almost none of the available evidence relates to the Lisa. It concedes, however, that throughout the summary judgment proceedings the district court allowed it to present its case using the Finder. Thus, dismissal of the Finder could only have an effect if the case were to go to trial. By virtue of Apple’s non-opposition to judgment on the works as a whole, we take it that the Lisa is not virtually identical to Windows 2.03, 3.0 or NewWave. As the district court found no material difference between the Lisa and the Finder, there can be no virtual identity as between the accused works and the Finder, either.

Both Microsoft and HP challenge the denial of their requests for attorney’s fees under 17 U.S.C. § 505.

At the time of the district court’s decision, controlling Ninth Circuit authority held that attorney’s fees were not available to a prevailing defendant under § 505 unless the plaintiffs action was frivolous or in bad faith.
Cooling Sys. & Flexibles, Inc. v. Stuart Radiator, Inc.,
Apple argues that despite this change in the law, remand is unnecessary because the district court also made findings that require the denial of attorney’s fees under the criteria set forth in
Lieb v. Topstone Industries,
AFFIRMED IN PART; REVERSED AND REMANDED IN PART.
Notes
. The Macintosh Finder is registered as a derivative work of the Lisa Desktop. Although the district court dismissed the Finder as a work in suit, the Macintosh interface has been referred to interchangeably with the Lisa during the course of this litigation.
.
Apple Computer, Inc. v. Microsoft Corp.,
Our treatment of facts throughout is truncated because the district court’s is so extensive.
. Windows 1.0 had a tiled windowing system in which the windows were connected together in a fixed pattern such that all open windows were simultaneously visible. An overlapping system allows windows to be stacked on top of one another and moved around the screen individually-
. These items relate to the "zooming rectangle" animation associated with the opening or closing of an icon into a window, the "dimming” of a folder icon that has been opened into a window, and the use of a trash can icon to depict the discard function. Each appears in both versions 1.0 and 3.0 of NewWave, but none is in any version of Windows.
. Although it does not concede that limiting doctrines were correctly applied to each alleged similarity, Apple does not ask us to review the many discrete decisions reflected in the district court's published opinions. We have done so only to the extent of being satisfied that none maltes a difference to the outcome, because we agree that the appeal turns on whether the district court’s approach was correct.
. The court's order that the four individual similarities in NewWave were to be compared at trial with their "equivalents” in Apple’s works for substantial similarity,
Apple VI,
. Since Apple contests only the legal standard of virtual identity, we do not consider whether summary judgment was appropriately entered on the merits under that standard.
. In the Agreement, Microsoft acknowledged "that the visual displays in [Windows 1.0] are derivative works of the visual displays generated by Apple’s Lisa and Macintosh graphic user interface programs.” Apple granted Microsoft a nonexclusive, royalty-free, nontransferable license "to use these derivative works in present and future software programs and to license them” to third parties for use in new software programs. Microsoft, in turn, granted Apple a similar license “to use any new visual displays created by Microsoft” during the next five years as part of its Windows retail software products; Apple waived any copyright, patent, trade secret or other claim against Windows 1.0; Microsoft agreed to delay the release of any versions of its Excel spreadsheet program that would run on computers other than the Macintosh; and Microsoft agreed to release an enhanced version of Microsoft Word (a word processing program) for the Macintosh.
. For the same reasons, the district court did not abuse its discretion in denying Apple's motion for leave to amend to add claims for breach of contract, rescission and unfair competition.
See Allen v. City of Beverly Hills,
. Apple also argues that the court erred by ruling that its audiovisual works are functional rather than aesthetic; that creative works are not copyrightable when they serve a functional purpose; and that Apple's works are "useful articles” or "compilations” under 17 U.S.C. § 101. We do not address these arguments specifically, because we do not read the district court's opinions as so holding. Rather, in the process of considering the scope of Apple’s copyright the court took into account the functional aspects of graphical user interfaces and the analogous range of protection available for compilations. As we shall explain, this was not improper.
. 17 U.S.C. § 102(b) codifies this principle, denying copyright protection "to any idea, procedure, process, system, method of operation, concept, principle, or discovery.”
. Microsoft also argues that it is entitled to attorney’s fees because Apple breached the 1985 Agreement by suing it for copyright infringement.
