A “reduction to practice” is the embodiment of the concept of an invention.
Very important: there are two ways that an invention may be reduced to practice:
1. By producing a physical embodiment of the invention (actual reduction to practice). For example,
- for an item of manufacture, provide a prototype or model of the invention.
- for a method, perform the method and confirm the results.
- for a composition of matter, synthesize or otherwise produce the composition.
2. By filing a patent application (constructive reduction to practice).
