If a patent has a term of rights, the patent publication number consists of 11 digits, the first four digits are the date, and the last seven digits are the patent number.

According to U.S. law, the term of patent protection is 20 years, so the 1978 patent, regardless of the search result, is also invalid and no longer patentable.

In addition, according to the query, the patent number 0882359 was issued in 1908, not 1978.

The publication number entered is invalid, either because it was entered incorrectly, or because it has not yet been disclosed during the application process, so it cannot be searched for publicly

You can't find it if it's not public!

This is to say that the US 19780882359 is not a publication number for a U.S. patent. You may have entered it incorrectly, so try changing the application number or patent number.

All I can say is that your public number is wrong.

Section 271 of the U.S. Patent Act, which deals with infringement, simply lists a list of infringements and states that the infringements are directed at "patentable inventions," but does not further indicate how to determine whether a patent has been infringed. U.S. courts use two types of evidence for use when interpreting patent claims. That is, evidence of how U.S. patent infringement is determined.

1. Internal evidence. That is, it consists of the claims of the patent, the description and the patent examination file. The court requires that all the internal evidentiary records be taken into account to determine the meaning of the claims.

The second is extrinsic evidence, ranging from dictionary definitions to expert evidence. The judge of the court of first instance has the discretion to decide whether or not to admit extrinsic evidence, but there is no need to consider extrinsic evidence if the intrinsic evidence can reasonably explain the claim.

2. Literal infringement. Literal infringement means that the allegedly infringing product or process has every technical feature in the claims compared with the claims of a patent; In other words, every qualifying or element of the claim can be found in the alleged infringing product or process, then the alleged infringing product or process constitutes a literal infringement of the patent.

3. Equivalent Infringement. When dealing with patent infringement disputes, the principle of equivalence has been the most problematic and controversial for a long time. The equivalence doctrine originated in the United States and is used to adjust the boundaries between an increasingly diverse range of inventions and the degree of interpretation of patent specifications, and is often used as a theoretical basis for strengthening patent rights.

Equivalent infringement refers to the literal infringement, which means: compared with the claims of a patent, one or several elements of the allegedly infringing product or process, although they are different from the limitations or elements in the claims, are only substantially different; In other words, if one or more elements of the allegedly infringing product or process are equivalent to one or more of the limitations or elements of the claims, the allegedly infringing product or process constitutes equivalent infringement of the patent.
