What is copyright?
Answer in brief
Copyright protects original works of authorship, such as writing, music, art and software, from the moment they are fixed in a tangible form. For most works created since 1978 it lasts for the author's life plus 70 years.
What it does not cover
- Ideas, methods and systems (patents may cover those).
- Names and short slogans (trademarks may cover those).
- Facts.
