About Copyright Symbol
© is the copyright symbol, used to declare the copyright ownership of a work. When searching for how to type the copyright symbol, the answer is right here.
The © symbol consists of a capital letter C surrounded by a circle and is the internationally recognized copyright notice. Marking a work with the © symbol, the name of the copyright owner, and the year of first publication constitutes a valid copyright notice.
【Historical Origin】 The history of the copyright symbol dates back to the 1909 U.S. Copyright Act, which required works to bear a copyright notice to receive protection. Although most countries have now eliminated the mandatory notice requirement, the © symbol remains widely used as an iconic symbol of intellectual property.
【Modern Applications】 © is frequently used in website footer copyright notices, publication title pages, software About pages, image watermarks, product packaging, and various scenarios requiring the declaration of copyright ownership.

What is the difference between the copyright symbol ©, registered trademark symbol ®, and trademark symbol ™?
© (U+00A9) indicates copyright protection, applicable to literary, artistic, musical, and other creative works; ® (U+00AE) indicates a registered trademark; ™ (U+2122) indicates a trademark in use but not necessarily registered. The objects of protection and legal implications of the three are completely different.
Is the © symbol mandatory in a copyright notice?
No, it is not mandatory. According to the Berne Convention, copyright arises automatically upon the creation of a work, without the need to mark the © symbol. However, marking © helps remind others and provides additional legal protection in some jurisdictions. Standard format: © Year Copyright Owner's Name.
