What is the ruling on using computer programs that are labeled "All rights reserved," and is it permissible to use trial programs that have only been used once, even though their validity period has expired?

The phrase "All rights reserved" signifies the financial and intellectual rights of the author, website, or programmer. It is not permissible to copy books, scientific materials, or programs bearing this phrase except with the permission of their owners, unless they specify that copying is allowed for personal use, not for commercial gain. Some websites offer their services for free and may permit copying for personal, non-commercial use. Quoting from displayed scientific materials is permissible, provided that the source is attributed. As for trial programs with a time limit, it is not permissible to use them after the expiration of the period except with the permission of their owners or by purchasing them.
