- Specific properties of the invention
The MPEP states: ‘Information reasonably necessary for finding prior art … may include technical information, such as … specific utilities of the invention, contemplated uses of the invention, or how the invention is made or used.’ This information helps the examiner assess whether the invention meets the utility requirement and to conduct a thorough prior art search.
