There are five basic rights that copyright law confers on the rights holder...
The right to reproduce the work
The right to create derivatives
The right to distribute copes to the public
The right to perform the work publicly
The right to display the work publicly
note that these rights are not absolute, there are exceptions (most notably the "fair use" doctrine)
Under US copyright law, there are no recordings that are public domain; they are either covered under state copyright law prior to 1972, under federal copyright law if published after that, and under federal copyright law if they were never published at all. The only possible public domain records would be some that were published before 1989 and after 1972 without the necessary copyright notice or registration.
You need permission from the copyright holder or an exemption in the law.
A website is considered a "literary work" under copyright law.
Yes. Under current US copyright law computer programs are considered "literary works"
Fortunately or unfortunately, copyright law isn't as black-and-white as that. If the design is protected by copyright, then only the copyright holder can copy it or authorize others to do so. Some copying is allowed by limitations, defenses, and exceptions in the copyright law itself. And the design may not even be protected in the first place, if the term has expired. So yes, copyright law means I can't put a Picasso on a t-shirt and sell it without a license. But I can take a photo of it or attempt to recreate it in my art class.
Under US copyright law, a copyright cannot be renewed after it expires. For works of US authors published in the US prior to 1963, copyright renewal had to be filed after 28 years.
All books are copyrighted. Under US copyright law, the act of creating automatically attaches copyright.
Under current US copyright law the maximum "standard" fine for "willful and deliberate" copyright infringement can be as high as $150,000.00 USD.
No, but there are caveats within the law that allow your homework to be completed anyway. See the link below for details.
Infringement is the use, without permission, of copyrighted material that does not fall under a "fair use" or other exception to copyright law,
Technology would typically be protected by patent law, with the exception of software, which can fall under both copyright and patent.
'p' inside a circle means 'protected by copyright law' and you are not allowed to reproduce it without permission from the author
