Non obviousness is a crucial concept in the field of patent law and innovation, particularly in nanotechnology. It refers to whether a new invention would be considered an obvious improvement or combination of existing technologies by someone skilled in the field. For an invention to be patentable, it must meet the criteria of being novel, non-obvious, and useful. In the context of nanotechnology, this can be particularly challenging due to the multidisciplinary nature and rapid advancements in the field.
