Legal origins and status
Philosophically, there is disagreement about the distinction between thought and language.
In the past it was often thought that the two could not be separated, and so a paraphrase could never exactly reproduce a thought expressed in different words.
At the opposite extreme is the view that concepts and language are completely independent, so there is always a range of ways in which a concept can be expressed.
In the United States, the doctrine originated from the 1879
Supreme Court

) described in a book might be available by patent, only the description itself was protectable by copyright. In later cases, the Supreme Court has stated that "unlike a patent, a copyright gives no exclusive right to the art disclosed; protection is given only to the expression of the idea—not the idea itself," and that "copyright's idea/expression dichotomy 'strike
a definitional balance between the First Amendment and the Copyright Act by permitting free communication of facts while still protecting an author's expression.'"
In the English decision of ''
Donoghue v. Allied Newspapers Ltd.'' (1938) Ch 106, the court illustrated the concept by stating that "the person who has clothed the idea in form, whether by means of a picture, a play or a book" owns the copyright. In the Australian decision of ''
Victoria Park Racing and Recreation Grounds Co. Ltd v. Taylor'' (1937) 58 CLR 479 at 498, Latham CJ used the analogy of reporting a person's fall from a bus: the first person to do so could not use the law of copyright to stop other people from announcing this fact.
Today, Article 1.2 of the
European Union Software Directive expressly excludes from copyright ideas and principles that underlie any element of a computer program, including those that underlie its interfaces. As stated by the European Court of Justice in SAS Institute Inc. v World Programming Ltd., "to accept that the functionality of a computer program can be protected by copyright would amount to making it possible to monopolize ideas, to the detriment of technological progress and industrial development."
Delineation
The idea–expression distinction has been delineated in various ways in
copyright jurisprudence. One view, advanced by Stanford law professor
Paul Goldstein, treats the concepts of "expression" and "idea" as metaphors for those parts of a work that are subject to copyright protection and those that are not. Thus, "idea" includes everything that is not copyrightable, especially ''abstract'' ideas, and "expression" includes all the copyrightable parts of a work, even when the work has not been copied literally.
Another view, advanced by
Pamela Samuelson

:
Samuelson criticizes the metaphor view for construing "ideas" too narrowly and distracting from the "policy reasons that support excluding more than just abstract ideas from copyright protection."
''Scènes à faire''
Some courts have recognized that particular ideas can be expressed effectively only by using certain elements or background. There are certain archetypal characters and even types of scenes that are frequently used by authors, due to both necessity to conform to genre conventions or even because the intended audience expects such archetypes. The
French name for the doctrine that protects the use of these archetypes is called ''
Scènes à faire
A ''scène à faire'' ( French for "scene to be made" or "scene that must be done"; plural: ''scènes à faire''; both pronounced ) is a scene in a work of fiction which is almost obligatory for a work in that genre.
In the United States, it als ...

.
The term "Scenes a faire" means "obligatory scene", a scene in a play that the audience "has been permitted to foresee and to desire from the progress of the action; and such a scene can never be omitted without a consequent dissatisfaction." The term was applied to copyright law in ''
Cain v. Universal Pictures'' (1942), where the
United States District Court for the Southern District of California ruled that "... similarities and incidental details necessary to the environment or setting of an action are not the material of which copyrightable originality consists."
The concept has been used by U.S. and U.K. courts.
The term is used both in the sense of a scene that follows inevitably from a situation,
or a standard scene that is always included in a particular genre of work.
Another court said "Under the ... doctrine of ''

'', courts will not protect a copyrighted work from infringement if the expression embodied in the work necessarily flows from a commonplace idea."
The concept has been extended to computer software, where some aspects may be dictated by the problem to be solved, or may be standard programming techniques.
In the
United States
The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 U.S. state, states and a federal capital district, Washington, D.C. The 48 ...
it is recognized that certain background elements are universal or at least commonplace in some types of work. For example, in
Walker v. Time Life Films, Inc.', 784 F.2d 44 (2d Cir. 1986), the
Second Circuit said that in a film about cops in the South Bronx it was inevitable that the scenery would include drunks, stripped cars, prostitutes, and rats. In ''
Gates Rubber Co. v. Bando Chemical Industries, Ltd.'', 9 F.3d 823 (10th Cir. 1993), the
Tenth Circuit held that hardware standards and mechanical specifications, software standards and compatibility requirements, computer manufacturer design standards, target industry practices and demands, and computer industry programming practices were unprotectable ''scènes à faire'' for computer programs. The principle must have a limit, however, so that something is outside the ''scènes à faire'' doctrine for South Bronx movies. In cases that, "held that scenes a faire . . . are not copyrightable," outcomes were due to a, "failure of the author to add anything original to the stock idea, rather than upon the impossibility of expressing the stock idea in a new form."
Merger doctrine
A broader but related concept is the merger doctrine. Some ideas can be expressed intelligibly only in one or a limited number of ways. The rules of a game provide an example. For example, in ''Morrisey v. Proctor & Gamble'', 379 F.2d 675 (1st Cir. 1967), a set of rules for sweepstakes based on entrants' social security numbers was not copyrightable because there were only a limited number of ways to express the underlying idea of the sweepstakes instructions. In such cases the expression merges with the idea and is therefore not protected.
There are cases where there is very little choice about how to express some fact or idea, so a copy or close paraphrase may be unavoidable.
In this case, the "merger doctrine" comes into play.
The fact or idea and the expression are seen as merged, and the expression cannot be protected.
The merger doctrine is typically applied only to factual information or scientific theories, not to imaginative works such as plays or novels where the author has a much broader choice of expression.
The merger doctrine has been applied to the user interface design of computer software, where similarity between icons used by two different programs is acceptable if only a very limited number of icons would be recognizable by users, such as an image looking like a page to represent a document.
However, in 1994 a U.K. judge in ''Ibcos Computers v. Barclays Mercantile Finance''
SR 275cast doubt on the merger doctrine, saying he was not comfortable with the idea that "if there is only one way of expressing an idea that way is not the subject of copyright."
United States courts are divided on whether merger prevents copyrightability in the first place, or should instead be considered when determining if the defendant copied protected expression.
Only one federal circuit, the
Ninth Circuit, has specifically held that merger should be considered a "defense" to
copyright infringement

as the plaintiff still carries the burden of proof that infringement occurred.
Criticism
A difficulty posed by the idea-expression distinction is that "

Learned Hand

in 1930's ''
Nichols v. Universal Pictures Corp.'', holding that while a fictional character
''can'' be copyrighted, it must be well-developed. Thirty years later, Hand reiterated that point in a case that held print patterns on fabrics copyrightable: "Obviously, no principle can be stated as to when an imitator has gone beyond copying the 'idea,' and has borrowed its 'expression.' Decisions must therefore inevitably be ad hoc."
The extension of the concept to visual art has vexed later courts. In 1978, the
Third Circuit heard ''
Franklin Mint Corp. v. National Wildlife Art Exchange'', where the plaintiff alleged a painter's work for the defendant was so similar to one it had previously commissioned as to be infringing. Judge
Joseph F. Weis Jr. wrote:
He also observed that under the distinction, a painter's copyright might be dependent on how

since the caped, flying superhero on the show had many significant differences, Judge
Jon O. Newman of the Second Circuit commented that adaptations from a textual medium to a visual one created additional problems in resolving idea-expression questions since the former is meant to be perceived linearly while the latter is taken in in its entirety.
In 2005, considering ''
Mannion v. Coors Brewing Co.'', where a ''photograph'' was alleged to have been imitated too indistinctly, Judge
Lewis A. Kaplan of the
Southern District of New York recounted the earlier cases and elaborated on those difficulties:
