How long is the legal protection period of patents, copyrights and trademarks in the United States?

Patent right: For an application for a patent for invention from May 29, 2000, the US Patent and Trademark Office will appropriately adjust the patent protection period according to the time delayed by the Patent and Trademark Office or the inventor. For example, due to the delay of the Patent and Trademark Office, the patent application is not approved within three years, and the Patent and Trademark Office will increase the patent term by more than three years. For invention patents filed before1June 8, 1995 but authorized after1June 8, 1995 or still valid on1June 8, 1995, the patent protection period is the longer of the following two periods: from the date of authorization 17 years or from the date of application.

Copyright: publications after the United States: 1978 65438+ 10/0/,the copyright term is from the time when the author completes his creation to 70 years after his death, which is within the scope of copyright law. If a work has more than one creator, the copyright will last for 70 years after the death of the last creator.

Anonymous or using a pseudonym, the protection period is 95 years after the publication of the work, or after 120 years from the date of creation. In addition, works that have not applied for registration are also protected by American copyright laws. Britain: Britain is the first country in the world to enact copyright law, and its copyright law is a model of common law system. All literary, dramatic, musical or artistic works, as long as they are first published in Britain, or the author is a British national or resident, are not protected by British copyright law without any formalities.

British copyright law only allows the use of works of art such as words, music, paintings or sculptures "for scientific research or personal research purposes". Therefore, in Britain, even if it is only for personal entertainment purposes, it is an infringement to use its works without the author's consent. France

Authors have the right to use their works in any form and obtain economic benefits from them, including the right to perform and copy. According to French copyright law, the author has the right to "renew" the copyright of artistic works, that is, after the author's works are auctioned publicly or sold through publishers, he still enjoys the inalienable right to participate in distribution.

According to Berne Convention, the universally recognized copyright protection period is 50 years.

According to China's Trademark Law, the validity period of a registered trademark is ten years, counting from the date of approval of registration. A registered trademark may apply for renewal of registration when it expires.

I don't know about America, but there are great differences between countries. As long as it is renewed, trademark rights have always been protected by law.
