According to the first paragraph of Article 22 of the Copyright Law of People's Republic of China (PRC), "the term of protection of the author's right of signature, modification and protection of the integrity of the work is not limited." Of course, I can provide you with more information about intellectual property protection.
Intellectual property protection refers to the protection of the rights and interests of intellectual property owners and related stakeholders through laws and other means. Intellectual property rights include trademark rights, patents, copyrights, etc. Every right has a different period and way of protection.
With regard to trademark rights, a trademark registrant enjoys the exclusive right to use a registered trademark, can use the trademark on the designated goods or services, and has the right to prohibit others from using the trademark without authorization. The term of protection of trademark rights is generally 10 years, but it can be extended.
With regard to the patent right, the inventor or applicant enjoys the right to apply for a patent and the patent right, and can exploit the invention exclusively within a certain period of time, and has the right to prohibit others from exploiting the invention without authorization. The protection period of patent right is generally 20 years, but there are some special circumstances that can terminate the protection in advance.
For copyright, the author enjoys the right to copy, distribute, perform and rent, and may prohibit others from using or spreading the work without authorization. The term of protection of copyright is generally 50 years before and after the author's death.
In order to strengthen the protection of intellectual property rights, all countries have formulated corresponding laws and regulations to punish violations of intellectual property rights. In China, laws and regulations on intellectual property protection include trademark law, patent law and copyright law. In addition, China has joined many international intellectual property protection organizations, such as the World Intellectual Property Organization, and strengthened cooperation and exchanges with other countries.
In addition to legal protection, enterprises can also take other measures to strengthen intellectual property protection. For example, establish a sound intellectual property management system, strengthen the intellectual property training and education for employees, and cooperate with professional institutions to evaluate intellectual property rights and safeguard rights.
In a word, intellectual property protection is an important means to promote innovation and economic development, which requires the joint efforts of the government, enterprises and all sectors of society to strengthen protection.
To sum up:
The duration of intellectual property protection is a complex issue, which varies according to different types of intellectual property rights and legal provisions. According to the laws of our country, the protection period of the right of signature, modification and the right to protect the integrity of a work is indefinite, that is, the author is still protected by law after his death.
Legal basis:
The first paragraph of Article 22 of the Copyright Law of People's Republic of China (PRC) stipulates: "The term of protection of the author's right of signature, modification and protection of the integrity of the work is not limited."
