Yes, if you have a copyright in any country covered under a multi-lateral treaty, such as the USA under the Berne Convention, your copyright must be honored and protected by the laws of the other 160 countries under that Convention.
Quite a bit. For information on US copyright laws, visit the website of the Copyright Office. For other countries, the WIPO website is a good place to start.
The United States has copyright relations with most countries throughout the world, and as a result of these agreements, they honor each other's citizens' copyrights. However, the United States does not have such copyright relationships with every country.
Simple words are not subject to copyright. Perhaps you mean "trademark"? Also, you don't "apply for a copyright" for anything; copyright is automatic, at least in the USA and any of the other 160 countries that follow the Berne Convention.
Yes most countries have a similar set of copyright laws to the US. There are multinational (WIPO, Berne Convention) regional (Buenos Aires, EU) and bilateral treaties in place that pledge to honor the signatories copyrights just as if they had been issued in the home country. Additionally there has been a significant push towards a worldwide standard that will equalize international copyright laws across all national boundaries.
Yes. Copyright as a legal concept originated in the UK in the early 18th century to combat unregulated copying of books. Nowadays almost every country has their own version of copyright laws, and many are a part of international treaties to enforce copyright law amonst themselves.
Yes, of course. just as well as in any other countries.
Not entirely, but all countries' copyright laws include a provision allowing certain limited exceptions for education. A good overview of US laws is linked below.
No. In the US, copyright protection for works in that period lasts for 95 years from publication. In other countries, copyright exists for at least 50 years from his death, and in many countries this has been extended to 70 years after his death.
The length of copyright over a work varies between different countries. For example, in the US, the copyright lasts 95 years since the date of publication or 120 years since its creation (if work is not published).Visit the link below to get the tenure of copyright in your country:http://en.wikipedia.org/wiki/List_of_countries%27_copyright_lengths#Legend
The 1911 song is in the public domain in the US, as well as Canada and other life + 50 countries; it is protected by copyright in life + 70 countries. A 1926 version may be protected in the US if it was renewed; in other countries it would depend on the year of death of the arranger or other rightsholders. Sound recordings have different terms of protection as well.
In the USA and more than 160 other countries of the Berne Union, the answer is that no copyright notice is necessary. This has been the law in the USA since 1989, meaning that things published prior to that, by US authors in the USA, were required to have copyright "notice", whether using the word "copyright", "copr." or the copyright symbol, followed by the publication date, followed by the name of the copyright owners. Laws for Copyright notice in other countries may vary.
A copyright protects original material (text, images, audio) recorded in a fixed format. There are two types of copyright, national and international. National copyright only protects original material produced within the country's borders. If your music was produced in the United States, then it is protected under US copyright laws, but not laws of other countries. International copyright, on the other hand, protects your music no matter where it was produced. A European artist can be protected by international copyright laws in the USA, for example.
