Can you provide an example of a patent-eligible transformation under MPEP 2106.05(c)?
MPEP 2106.05(c) provides a classic example of a patent-eligible transformation from the case of Tilghman v. Proctor:
In that case, the claim was directed to a process of subjecting a mixture of fat and water to a high degree of heat and included additional parameters relating to the level of heat, the quantities of fat and water, and the strength of the mixing vessel. The claimed process, which used the natural principle that the elements of neutral fat require that they be severally united with an atomic equivalent of water in order to separate and become free, resulted in the transformation of the fatty bodies into fat acids and glycerine.
This example demonstrates a particular transformation of a specific article (fat and water mixture) into a different state (fat acids and glycerine) through a well-defined process. Such transformations are more likely to be considered patent-eligible under the particular transformation consideration.
