State of the art
From Wikipedia, the free encyclopedia
The state of the art is the highest level of development, as of a device, technique, or scientific field, achieved at a particular time.

The phrase "state of the art" should be hyphenated when it is used as an adjective, e.g.:
- "This machine is an example of state-of-the-art technology",
but not when used as a noun, as in the following sentence:
- "The state of the art in this field is mostly related to the X technology".
Cutting edge as a synonym of the term can be used as a noun.
The earliest known usage of the term "state of the art" dates back to 1910 from an engineering manual by H.H. Suplee titled Gas Turbine.[dubious ] It reads, "In the present state of the art this is all that can be done."
In the context of the European and Australian patent law, the term "state of the art" is a concept used in the process of assessing and asserting novelty and inventive step, [1] and is a synonym of the expression "prior art". In the European Patent Convention (EPC), "[the] state of the art shall be held to comprise everything made available to the public by means of a written or oral description, by use, or in any other way, before the date of filing of the European patent application" according to Article 54(2) EPC. Due account should be taken of Article 54(3) EPC as well, but merely for the examination of novelty.
The expression "background art" is also used in certain legal provisions, such as Rule 42(1)(b) and(c) EPC (previously Rule 27(1)(b) and (c) EPC 1973), and has the same meaning. [2]
