Pencils can be patented. For example, Chinese drawing pencils, paper roll pencils, and core storage pencils all have their own patents. But if you want to speculate on rubber-tipped pencils, That has been a common practice for so many years. "New" requirements that no longer meet patent requirements cannot be applied for.

But if you find a pencil made of a new material, such as one that doesn’t use wood, and some conventional materials you’ve used in the past, that’s ok!

Eraser-tipped pencils have not been patented and anyone can make them. However, like Zhonghua brand drawing pencils, their materials and appearance are patented, so they cannot be imitated.

Do you understand?
