A copyright disclaimer is a statement that claims ownership of original content, or discloses your use of copyrighted materials for “fair use” purposes.
There are two types of copyright disclaimers:
Copyright disclaimer under Section 107 of the Copyright Act: This disclaimer appears on content (commonly YouTube videos) that uses someone else’s copyrighted content. Including this statement of “fair use” helps protect against copyright infringement claims.
Original work copyright disclaimer: This disclaimer can be used on blogs, websites, images, videos, music, and even social media to establish your ownership over original content. Having this statement helps protect your work against theft.
