In computing, source code is any collection of code, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code that can be executed by the computer. The machine code might then be stored for execution at a later time. Alternatively, source code may be interpreted and thus immediately executed.
Limitations on exclusive rights: Computer programs is the title of the current form of section 117 of the U.S. Copyright Act. In United States copyright law, it provides users with certain adaptation rights for computer software that they own.
The first-sale doctrine is a legal concept that plays an important role in United States copyright law by limiting the rights of an intellectual property owner to control resale of products embodying its intellectual property. The doctrine enables the distribution chain of copyrighted products, library lending, giving, video rentals and secondary markets for copyrighted works. In trademark law, this same doctrine enables reselling of trademarked products after the trademark holder puts the products on the market. In the case of patented products, the doctrine allows resale of patented products without any control from the patent holder. The first sale doctrine does not apply to patented processes. The doctrine is also referred to as the "right of first sale", "first sale rule", or "first sale exhaustion rule".
Ripping is extracting all or parts of digital contents from a container. Originally, it meant to rip music out of Amiga games. Later, the term was used to extract WAV or MP3 format files from digital audio CDs, but got applied as well to extract the contents of any media, most notably DVD and Blu-ray discs.
Software copyright is the application of copyright law to machine-readable software. While many of the legal principles and policy debates concerning software copyright have close parallels in other domains of copyright law, there are a number of distinctive issues that arise with software. This article primarily focuses on topics particular to software.
Anti-circumvention refers to laws which prohibit the circumvention of technological barriers for using a digital good in certain ways which the rightsholders do not wish to allow. The requirement for anti-circumvention laws was globalized in 1996 with the creation of the World Intellectual Property Organization's Copyright Treaty.
White-Smith Music Publishing Company v. Apollo Company, 209 U.S. 1 (1908), was a decision by the Supreme Court of the United States which ruled that manufacturers of music rolls for player pianos did not have to pay royalties to the composers. The ruling was based on a holding that the piano rolls were not copies of the plaintiffs' copyrighted sheet music, but were instead parts of the machine that reproduced the music.
Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 is a decision from the United States Court of Appeals for the Second Circuit that addressed to what extent non-literal elements of software are protected by copyright law. The court used and recommended a three-step process called the Abstraction-Filtration-Comparison test. The case was an appeal from the United States District Court for the Eastern District of New York in which the district court found that defendant Altai's OSCAR 3.4 computer program had infringed plaintiff Computer Associates' copyrighted computer program entitled CA-SCHEDULER. The district court also found that Altai's OSCAR 3.5 program was not substantially similar to a portion of CA-SCHEDULER 7.0 called SYSTEM ADAPTER, and thus denied relief as to OSCAR 3.5. Finally, the district court concluded that Computer Associates' state law trade secret misappropriation claim against Altai was preempted by the federal Copyright Act. The appeal was heard by Judges Frank Altimari, John Daniel Mahoney, and John M. Walker, Jr. The majority opinion was written by Judge Walker. Judge Altimari concurred in part and dissented in part. The Second Circuit affirmed the district court's ruling as to copyright infringement, but vacated and remanded its holding on trade secret preemption.
The copyright symbol, or copyright sign, ©, is the symbol used in copyright notices for works other than sound recordings. The use of the symbol is described by the Universal Copyright Convention. The symbol is widely recognized but, under the Berne Convention, is no longer required in most nations to assert a new copyright.
Public-domain software is software that has been placed in the public domain: in other words, there is absolutely no ownership such as copyright, trademark, or patent. Software in the public domain can be modified, distributed, or sold even without any attribution by anyone; this is unlike the common case of software under exclusive copyright, where software licenses grant limited usage rights.
Proprietary software, also known as non-free software, is computer software for which the software's publisher or another person reserves some rights from licensees to use, modify, share modifications, or share the software. It sometimes includes patent rights.
The WIPO Copyright and Performances and Phonograms Treaties Implementation Act, is a part of the Digital Millennium Copyright Act (DMCA), a 1998 U.S. law. It has two major portions, Section 102, which implements the requirements of the WIPO Copyright Treaty, and Section 103, which arguably provides additional protection against the circumvention of copy prevention systems and prohibits the removal of copyright management information.
The copyright law of Australia defines the legally enforceable rights of creators of creative and artistic works under Australian law. The scope of copyright in Australia is defined in the Copyright Act 1968, which applies the national law throughout Australia. Designs may be covered by the Copyright Act as well as by the Design Act. Since 2007, performers have moral rights in recordings of their work.
The Copyright Act of 1976 is a United States copyright law and remains the primary basis of copyright law in the United States, as amended by several later enacted copyright provisions. The Act spells out the basic rights of copyright holders, codified the doctrine of "fair use", and for most new copyrights adopted a unitary term based on the date of the author's death rather than the prior scheme of fixed initial and renewal terms. It became Public Law number 94-553 on October 19, 1976 and went into effect on January 1, 1978.
The Digital Millennium Copyright Act (DMCA) is a 1998 United States copyright law that implements two 1996 treaties of the World Intellectual Property Organization (WIPO). It criminalizes production and dissemination of technology, devices, or services intended to circumvent measures that control access to copyrighted works. It also criminalizes the act of circumventing an access control, whether or not there is actual infringement of copyright itself. In addition, the DMCA heightens the penalties for copyright infringement on the Internet. Passed on October 12, 1998, by a unanimous vote in the United States Senate and signed into law by President Bill Clinton on October 28, 1998, the DMCA amended Title 17 of the United States Code to extend the reach of copyright, while limiting the liability of the providers of online services for copyright infringement by their users.
The Copyright Act 1911, also known as the Imperial Copyright Act of 1911, is an Act of the Parliament of the United Kingdom (UK) which received Royal Assent on 16 December 1911. The act established copyright law in the UK and the British Empire. The act amended existing UK copyright law, as recommended by a Royal Commission in 1878 and repealed all previous copyright legislation that had been in force in the UK. The act also implemented changes arising from the first revision of the Berne Convention for the Protection of Literary and Artistic Works in 1908.
Works are in the public domain if they are not covered by intellectual property rights at all, or if the intellectual property rights to the works have expired.
The copyright law of South Africa governs copyright, the right to control the use and distribution of artistic and creative works, in the Republic of South Africa. It is embodied in the Copyright Act, 1978 and its various amendment acts, and administered by the Companies and Intellectual Property Commission in the Department of Trade and Industry. As of March 2019 a major amendment to the law in the Copyright Amendment Bill has been approved by the South African Parliament and is awaiting signature by the President.
Typefaces, fonts, and their glyphs raise intellectual property considerations in copyright, trademark, design patent, and related laws. The copyright status of a typeface—and any font file that describes it digitally—varies between jurisdictions. In the United States, the shapes of typefaces are not eligible for copyright, though the shapes may be protected by design patent. Typefaces can be protected in other countries, including the UK, Germany, and France, by industrial design protections that are similar to copyright or design patent in that they protect the abstract shapes. Additionally, in the US and in some other countries, computer fonts—the digital instantiation of the shapes as vector outlines—may be protected by copyright on the computer code that produces them. The name of a typeface may also be protected as a trademark.
Remedies for copyright infringement in the United States can be either civil or criminal in nature. Criminal remedies for copyright infringement prevent the unauthorized use of copyrighted works by defining certain violations of copyright to be criminal wrongs which are liable to be prosecuted and punished by the state. Unlike civil remedies, which are obtained through private civil actions initiated by the owner of the copyright, criminal remedies are secured by the state which prosecutes the infringing individual or organisation.
