Let's say there is a patent for a gear covered in gasoline where the gasoline is explicitly mentioned to be used for the lubrication of the gear. Can I patent the same gear covered in gasoline embodiment where gasoline is explicitly used for cooling as it evaporates? Or let's say there is a patent of a gear covered in sugar which is explicitly for protection against hear. Can I patent the same gear covered in sugar where sugar is explicitly for protection against oxidation? Another example is, an antibody coated eye contact lens to prevent infection but also an antibody coated contact lens to lubricate the eye (supposedly that both functions of antibodies, i.e. infection prevention and lubrication are known).
