If you legally own a product you are allowed to make a "back up" copy for personal use. However unless your copies would qualify as "back up" or "fair use" no you can't legally duplicate a copyrighted product. It would be an infringement of the original authors' rights to control duplication and creation of derivatives of their work.
Possibly. It depends on the type of material, the extent of it, the proposed use, and more.
No copyright prevents others to copy your work without your permission. Plagiarism is what you are thinking of. Plagiarism is illegal.
Copyright law gives the creator of a work the exclusive right to copy, alter, distribute, or perform/display the work, or authorize others to do so, for a limited time. It is used to encourage creativity and discourage infringement.
Of course it is. You can use anything in the public domain without asking permission or paying for rights. But there is a distinction between copyright infringement and plagiarism; they are not identical. Taking material from any source, and allowing the appearance that it is your original work, is plagiarism. You might not go to jail for it depending on its extent, but you would surely end any hope of a distinguished academic career.
That phrase could mean several things. It could refer to a letter that is protected by copyright, or a letter allowing use of someone's copyright (i.e., a license).
It encourages creativity by allowing creators to retain the value of their works.
Often professional photographers retain the copyright to pictures they take so it is technically illegal to make your own copies. Stores like Wal-Mart sometimes adopt policies to prevent any complaints about aiding copyright infringement. Your options include trying other stores, buying copies from the original photographer, or getting the original photographer to sign a release allowing copies to be made.
If a work was registered during a period that required renewal (in the US, 1923-1963) but was not renewed, protection has expired and the work is in the public domain. If a work is likely to be protected but the rightsholder cannot be identified or located, the material is considered an "orphan work." There is currently no law allowing the unlicensed use of orphan works: you can try for years to locate and contact the rightsholder, but if you use the material without their permission and they magically crawl out of the woodwork, you are as guilty of infringement as you would have been had you not attempted to contact them at all, and they can sue you for up to $150,000 per infringement even if real damages were nowhere near that.
The protection of the person who created a specific work of art, music or anything else. The person who owns the copyright is to be paid for its use - this is how they earn their income, and it is their right to collect fees for the use of their works. It also prevents someone else from claiming something as their own when they know they had no rights to it in the first place.
Make an agreement, generally in writing, which spells out exactly what you're allowing them to do.
The copyright act affects various issues, including the protection of creative works such as books, music, films, and software. It addresses issues related to infringement, fair use, and licensing, determining the rights and obligations of creators, users, and distributors. Additionally, it impacts digital piracy, intellectual property rights, and the balance between promoting creativity and allowing access to copyrighted content.
It's not strictly a paradox; fair use is a clause in the copyright law allowing certain limited unlicensed uses. It is only one of many limitations, defenses, and exceptions to the exclusive rights of the copyright holder.
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.
Fair use is a defense in the US copyright law allowing certain specific unlicensed uses in cases of criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research.Determination is generally made using the "four factors:"Purpose of the useNature of the workAmount and substantiality of the portionEffect on the potential market for the original workAt the moment, decisions are also affected by whether the use is considered to be transformative: taking something designed for entertainment and using part of it for education, for example.
