Definition & Meaning

A patent caveat was a legal document that allowed inventors to notify the U.S. Patent Office of their intention to file a patent application in the future. Introduced by the U.S. Patent Act of 1836, it was designed to protect an inventor's rights by preventing others from obtaining a patent for the same invention during the caveat's validity period. Unlike modern provisional applications, patent caveats did not include specific claims about the invention. They were confidential and filed in the archives of the Patent Office, which meant details remained secret. Patent caveats were discontinued in 1909.

Legal Use & context

Patent caveats were primarily used in the field of intellectual property law. They provided a mechanism for inventors, including U.S. citizens and certain aliens, to secure their inventions temporarily while preparing a formal patent application. Although patent caveats are no longer in use, understanding their historical context can be beneficial for those studying patent law or involved in the patent application process today.

Example 2: A researcher working on a novel process files a caveat to ensure that no one else can patent the same process while they are completing their formal application. (hypothetical example)
