This article explains “Invention and Creation of Element Changes” from four points.

1. Can improvements in existing technology be patented.

2. Creative judgment of such patents.

3. How to determine creativity if a part of the product is replaced.

4. If the system and solution are simplified, does it still have creativity.

Can I apply for patent protection for some modifications made to the existing products on the market?

Can apply for a patent. In fact, most creations are “improvements” based on existing technology. This improvement belongs to the category of making changes to some technical features, generally including changes in feature relationships, feature substitution, and feature omission. However, whether authorization can be granted still depends on whether the modified technical solution is creative.

So how to judge its creativity?

If there are changes in the shape, size, proportion, position, or functional relationship of a product compared to existing technology, and these changes bring unexpected technical effects, then it has creativity.

If a part of the product is replaced, such as changing the original product from A+B+C to A+B+D. How to determine if it is creative?

If the effect after replacement does not exceed expectations, then this type of replacement lacks creativity. But if some technical difficulties are overcome, then it is creative.

If the product is simplified, can a simplified solution be used?

If removing certain components, modules, or omitting a certain step can still maintain all original functions, or even bring other effects, then it definitely has creativity; On the contrary, if certain components, modules, or steps are removed or omitted, and the functionality is also lost, then this simplification lacks creativity.
