How does the USPTO determine if a process can make a materially different product?
The USPTO’s Manual of Patent Examining Procedure (MPEP) 806.05(f) provides guidance on determining if a process can make a materially different product. The key considerations are:
- The claimed process must be capable of producing a product that is materially different from the one claimed.
- The difference must be significant and not merely a trivial variation.
- The examiner must provide a reasonable example of how the claimed process could make a different product.
For instance, the MPEP states:
“Allegations of different processes or products need not be documented.”
This means that the examiner can propose hypothetical examples to demonstrate distinctness, but these examples should be reasonable and based on the technology involved.
