In cases where copyright-sensitive use (for example. B a copy for commercial use) is required, an authorization can normally be obtained: the Berne Convention is the most important international convention on copyright. It defines the common framework: copyright, guaranteed minimum duration of copyright, acts subject to authorisation, etc., which all contracting states must include in their national laws and extend to foreign artists and authors. Differences in the definition of copyright duration by national copyright laws and the list of categories of copyrighted works therefore lead to different definitions of the public sector on a national basis. The detailed list of categories of copyrighted works – and the specific definition and scope of each – may vary slightly from country to country, but it generally includes scientific articles, essays, novels, short stories, poems, plays and other literary works; Drawings, paintings, photographs, sculptures and other works of art in two and three dimensions; films and other audiovisual works; Musical compositions; Software and others. In addition to these treaties, the Anti-Counterfeiting Trade Agreement (ACAC) is a multilateral treaty that governs several aspects of intellectual property, including copyright. Since February 2012[update], ACTA has been signed by 31 countries, but only ratified by Japan.  If ACTA is ratified by six or more signatories, it will enter into force thirty days later.  Most national copyright laws recognize two distinct types of copyright rights: the Berne Convention grants authors certain exclusive rights, including the creation or authorisation of public translations, reproductions and recitations; and the protection of moral rights. Each Member State may authorise certain uses of works in its legislation, such as a legal licence for the reproduction and reflection of works by educational institutions, for example.B. The Berne Convention limits the effects of such exceptions on the exclusive rights of the copyright holder by providing that the normal exploitation of the work and the legitimate interests of the author are not affected. The International Intellectual Property Alliance (IIPA) is an alliance of trade associations in the “copyright-based industries” of the United States. All the countries of Buenos Aires are now also parties to the Bern Convention, but the elements of Buenos Aires are still used in modern times, as the rule of shorter time.
The Berne Convention stipulates that copyright protection should be extended in all signatory states to at least “literary and artistic works,” including “any production in the literary, scientific and artistic fields, regardless of the nature or form of their expression.” Although national laws are different, fundamental rights are the same in most countries under international conventions and agreements (mainly the Bern Convention) that provide a common framework that national laws must respect to ensure that countries respect the rights of foreign authors. As a general rule, copyright exceptions and restrictions are tested in three stages, originally established by the Berne Convention and repeated in a number of other international agreements. In short, the Berne Convention provides that an exception or restriction of copyright is permitted only if the UCC embodies the principle of national treatment, not automatic protection. A UCC member state is not required to grant automatic protection to foreign work if national protection procedures are not followed. Therefore, the symbol ©, the name and date of the first publication should be put on the work in order to properly publicize the copyright. Several international treaties promote relatively consistent protection of copyright from one country to another.
