{{Intellectual property}}

'''Structure, sequence and organization''' ('''SSO''') is a term used in the United States to define a basis for comparing one software work to another in order to determine if copying has occurred that infringes on copyright, even when the second work is not a literal copy of the first.

The term was introduced in the case of ''[[Whelan v. Jaslow]]'' in 1986.{{sfn|Kappel|1991|p=699}}

The method of comparing the SSO of two software products has since evolved in attempts to avoid the extremes of over-protection and under-protection, both of which are considered to discourage innovation.{{sfn|Abramson|2001|p=57}}

More recently, the concept has been used in a''[[Oracle majorAmerica, caseInc. broughtv. against [[Google]], by [[Oracle Corporation|OracleInc.]].''{{sfn|Lee|2012}}

{{main|Whelan v. Jaslow}}

''Whelan Assocs., Inc. v. Jaslow Dental Laboratory, Inc.'' was a landmark case in defining principles that applied to copyright of computer software.{{sfn|Graham|1999|p=88}}

Line 33:

A technical criticism of ''Whelan'' is that it fails to distinguish between the sequence in which instructions are presented in the text of a program and the sequence in which the instructions are executed - the program's behavior. Both the textual and behavioral aspects have their own SSO, but a programmer would see the textual SSO as relatively unimportant.{{sfn|Galler|1995|p=87}}

A related point is that although the text of a computer program may be an "original work of authorship", protected by copyright laws., the algorithms and designs that the program embodies may be better considered to be "processes, procedures, systems, methods of operation", which are explicitly excluded from copyright protection although they may be protectable by patents.{{sfn|Hansen|2006|p=196}}

The distinction between the code's SSO, which is protected by copyright, and the protocol or algorithm, which is patentable, is however extremely difficult to maintain.{{sfn|Granstrand|2003|p=407}}

Line 47:

==Computer Associates v. Altai==

{{main|Computer Associates Int. Inc. v. Altai Inc.}}

In ''[[Computer Associates Int. Inc. v. Altai Inc.]]'' in 1992 the Second Circuit Court of Appeals agreed with the conclusion in ''Whelan'' that the structure, sequence and organization of a program might bybe protected by copyright where appropriate.{{sfn|Takeyama|Gordon|Towse|2005|p=11}}

However, the court went on to say, "As we have already noted, a computer program's ultimate function or purpose is the composite result of interacting subroutines. Since each Subroutine is itself a program, and thus, may be said to have its own 'idea,' Whelan's general formulation that a program's overall Purpose equates with the program's idea is descriptively inadequate."{{sfn|Hamilton|Sabety|1997|p=250}}

Line 65:

However, the courts have tried to maintain common standards and tests for both types of SSO.{{sfn|Epstein|2006|p=11-17}}

Following the 1986 ''Broderbund'' ruling, [[Lotus Development Corporation]] sued two competing spreadsheet program vendors for copying the look and feel of their [[Lotus 1-2-3]] spreadsheet program, and [[Apple ComputersComputer]] sued [[Microsoft]] and [[Hewlett-Packard]] for copying the [[Classic Mac OS|Macintosh operating system]]'s use of icons, pull-down menus and a mouse pointing device. Both companies drew criticism, since key elements of their look and feel had been introduced earlier by [[VisiCalc]] and [[Xerox]].

A 1992 federal court finding against Apple largely rejected the idea that copyright law could protect look and feel.

The Lotus case went to the Supreme Court, which could not reach a decision, thus by default confirming the lower court's 1995 declaration that the words and commands used to manipulate the spreadsheet were a "method of operation", which is not subject to copyright.{{sfn|Overbeck|Belmas|2011|p=270-271}}

Line 75:

The ideas can be implemented in a competing program as long as the developers do not copy the original expression.{{sfn|Yusuf|2008|pp=51-52}}

With a [[clean room design]] approach one team of engineers derives a functional specification from the original code,

and then a second team uses that specification to design and builtbuild the new code.

This was piloted in the mid-1980s by a team from [[Phoenix Technologies]] to produce a [[BIOS]] functionally equivalent to that of the [[IBM Personal Computer]] without infringing on IBM's copyright.{{sfn|Schwartz|2001}}

Line 84:

On May 31, 2012 the judge ruled that "So long as the specific code used to implement a method is different, anyone is free under the Copyright Act to write his or her own code to carry out exactly the same function or specification of any methods used in the Java API."{{sfn|Mullin|2012}}

In reviewing the ''[[Oracle v. Google]]'' case history, the court noted:{{blockquote|...the above summary of the development of the law reveals a trajectory in which enthusiasm for protection of "structure, sequence and organization" peaked in the 1980s, most notably in the Third Circuit’s ''Whelan'' decision. That phrase has not been re-used by the Ninth Circuit since ''Johnson Controls'' in 1989, a decision affirming preliminary injunction. Since then, the trend of the copyright decisions has been more cautious. This trend has been driven by fidelity to Section 102(b) and recognition of the danger of conferring a monopoly by copyright over what Congress expressly warned should be conferred only by patent. This is not to say that infringement of the structure, sequence and organization is a dead letter. To the contrary, it is not a dead letter. It is to say that the ''Whelan'' approach has given way to the ''Computer Associates'' approach, including in our own circuit. See ''[[Sega Enters., Ltd. v. Accolade, Inc.]]'', 977 F.2d 1510, 1525 (9th Cir. 1992); ''[[Apple Computer, Inc. v. Microsoft Corp.]]'', 35 F.3d 1435, 1445 (9th Cir. 1994).{{sfn|Alsup|2012}}}}
