Q: Would creating a knife blade with similar shape but different ornament from one patent and adding to a handle from a
Different manufacturers knife handle that has a separate patent be infringing?
There is nothing to prevent you from combining two or more elements from different patents to produce somethin novel and patentable. However the product needs to be novel and non-obvious.
On the other hand if your question is whether ou would be infringing if you took a patentad product, added an ornamental element to it, and sold it - thae answer is very probably yes, you would be infringing. So don't do it!
Patent infringement occurs when someone makes, uses, sells, or offers to sell a patented invention without the patent owner's permission. If the knife blade is only similar in shape but has a different ornamentation, it might not infringe on the original patent, provided the ornamentation is the patented aspect.
However, combining it with a handle from a different manufacturer that's separately patented can raise concerns. If the combination results in a new product that falls within the claims of either patent, there could be potential infringement.
Determining infringement often involves a detailed analysis of the patent claims and the allegedly infringing product. It's crucial to conduct a thorough patent analysis before proceeding with any such product design. Always consult with a colleague or another attorney to get a detailed understanding of the potential risks.
