In the context of contract manufacturing of health supplements, the term "patent requirements" refers to the legal criteria that must be met when applying for a patent for a health supplement-related invention. These requirements typically include utility, novelty, non-obviousness, and industrial applicability.

Firstly, utility refers to the requirement that the invention must have practical utility and provide substantial benefits to the technical field of health supplements. In other words, the invention must be capable of solving practical problems or offering useful functions.

Secondly, novelty dictates that the invention must not have been publicly disclosed or described in existing prior art before the application date. This means that the invention should be new and not already known or available to the public in the same field.

Thirdly, non-obviousness entails that the invention must not be obvious to a person skilled in the relevant technical field. It should involve an inventive step that is not easily deducible by someone with ordinary knowledge and skills in the field. In other words, the invention should possess a certain level of innovation and inventive creativity.

Lastly, industrial applicability requires that the invention is capable of being used or applied in an industrial or manufacturing setting. It should have practical industrial utility and be capable of being produced or implemented in a commercially viable manner.

Meeting these patent requirements is essential for securing a patent for inventions in the contract manufacturing of health supplements. Only when the invention meets the criteria of utility, novelty, non-obviousness, and industrial applicability can a contract manufacturing company be eligible to apply for patent protection.
