Inventive step and non-obviousness
Concept in patent law / From Wikipedia, the free encyclopedia
The inventive step and non-obviousness reflect a general patentability requirement present in most patent laws, according to which an invention should be sufficiently inventive—i.e., non-obvious—in order to be patented.[1] In other words, "[the] nonobviousness principle asks whether the invention is an adequate distance beyond or above the state of the art".[2]
The expression "inventive step" is used in European Patent Convention and in Patent Cooperation Treaty, while the expression "non-obviousness" is predominantly used in United States patent law.[1] The expression "inventiveness" is sometimes used as well.[3] Although the basic principle is roughly the same, the assessment of the inventive step and non-obviousness varies from one country to another. For instance, the practice of the European Patent Office (EPO) differs from the practice in the United Kingdom.
