What is the significance of “materially different” in process of making and product made distinctness?

The term “materially different” is crucial in establishing distinctness between a process of making and a product made. According to MPEP 806.05(f), distinctness can be shown if:

• The process can make another materially different product, or
• The product can be made by another materially different process.

The significance of “materially different” lies in its implications:

1. It establishes a threshold for distinctness that goes beyond minor or insignificant differences.
2. It requires the examiner to provide an example that demonstrates a substantial difference in either the process or the product.
3. It helps prevent unnecessary restrictions by ensuring that the differences between inventions are meaningful and not merely superficial.

While the MPEP doesn’t provide a precise definition of “materially different,” it generally implies a difference that would result in a product with different properties, characteristics, or uses, or a process with significantly different steps or conditions.
