The calculation of the starting and ending time of the copyright protection period

The term of protection of a work's copyright was usually 20 years, but the copyright owner could extend the term of protection. The specific extension of the term of protection was the legal practice of various countries. For example, the copyright protection period in China was 120 years for the author's lifetime and 50 years after his death, while the copyright protection period in the United States was 175 years for the author's lifetime and 40 years after his death. During the extended period, the copyright owners still retained the copyright of their works unless they voluntarily gave up the rights. If the copyright owner does not give up his rights, his personal rights and property rights (such as the right to profit, adaptation rights, translation rights, etc.) are protected by the copyright law after the work is published.

No, the term of copyright protection was established in the early 1990s. The current term of protection is 20 years from the date of creation. However, according to article 34 of the copyright law, the author's personal rights, property rights, and other personal rights could be protected indefinitely. Therefore, even if the author did not exercise the copyright after the end of the copyright protection period, his personal rights and other personal rights could still continue to be protected.

The term of protection of a copyright was usually 20 years from the date of creation of the work. However, the copyright owner can retain the copyright rights of the work without paying any copyright fees to any organization in the 20th, 25th, 30th, and 21st years. The specific legal provisions for the extension of the term of protection vary from country to country. Some countries have laws that allow the copyright owner to extend the term of protection indefinitely, while others provide that the extension of the term of protection is only allowed under certain conditions. The copyright includes the copyright law and the copyright distribution law. The copyright law provides that the rights enjoyed by the copyright owner include the right to create, publish, adapt, translate, compile, display, and so on. At the same time, the copyright distribution law stipulated that the copyright owner's copyright income should be distributed according to the proportion.

The term of protection of a copyright was usually 50 to 200 years from the date of creation. The specific period of protection is determined by the copyright law, but the copyright laws of different countries and regions may be different. For example, in the United States, the copyright protection period is 20 years, but the author can extend the protection period up to 40 years. In the UK, copyright protection lasts for 10 years, but the author can apply to the court for an extension of the protection period within 3 years after the expiration of the protection period. After the copyright protection period expired, if the author did not raise any objections, the copyright would be automatically extended. However, if the author fails to provide sufficient evidence in the application for extension of the term of protection, the term of protection may be shortened again. Therefore, authors should reasonably protect their copyrights and promptly submit applications to safeguard their legal rights.

The copyright protection period was 20 years from the day the author created the work. However, the copyright owner can extend the term of protection of the copyright by up to 10 years. The copyright owner may modify, use, adapt, or permit others to use his work indefinitely during the term of protection of the copyright.

The copyright protection period was 50 years after the author's death.

The term of protection for the copyright of a work refers to the time limit for the copyright owner to prove the ownership of the copyright to the National copyright Bureau or other relevant agencies through registration. Under normal circumstances, the term of protection of the copyright registration of a work is the same as the term of protection of the copyright, which is 10 years. However, according to the specific circumstances, the copyright owner can extend the protection period by way of extension. For example, the copyright owner could extend the term of protection of his copyright at the National copyright Bureau. Therefore, the length of the copyright protection period depends on the situation of the copyright owner and the changes in national policies.

The copyright protection period was 20 years, but the copyright was valid during the author's lifetime and 50 years after his death. If the author's copyright was not renewed within 50 years of his death, the copyright would be automatically extinguished.

The term of protection of a copyright is for the author's life and a reasonable period after his death, usually 50 years. However, the legal provisions for the extension of the term of protection by the copyright owner were more complicated and needed to be judged under specific circumstances.

The copyright protection period was 20 years. The author enjoyed the copyright for 20 years after the creation of the work. If the author's copyright was still valid after 20 years, he could continue to enjoy the copyright until the end of his life.
