The document discusses non-obviousness, which is a requirement for patentability. To satisfy non-obviousness, an invention must not be obvious to someone with skill in the related field. While it does not need to be a brilliant act of new genius, the combination of elements cannot be obvious and must provide a utility greater than the sum of the parts. The patent application process involves initially filing a provisional application, then a formal application which undergoes review and potential appeals before a patent is issued. The process is lengthy and obtaining a US patent can cost over $1 million due to extensive legal costs.
