Simple English definitions for legal terms
Read a random definition: liability
A novel is something that is new. When someone creates something new, they may want to get a patent to protect their idea. However, in order to get a patent, the idea must be truly new and not something that has already been known or used by others. This is called the novelty test. If the idea fails the novelty test, it cannot be patented.
Novelty refers to something that is new and original. In the context of patents, novelty is a requirement for obtaining a patent. An invention may fail the novelty test for various reasons. For example, if the invention was known or used by others in the United States before the claimed invention date, it cannot be considered novel. Similarly, if the invention was patented in any country more than a year before the present patent application, it cannot be considered novel.
These examples illustrate how novelty is a requirement for obtaining a patent and how an invention must be new and original to be considered novel.
