Definition

Something that cannot be legally protected by a patent, meaning it cannot be claimed as an invention or exclusive right.

Example

The new idea was deemed unpatentable because it was too similar to existing products.

Conversation

Did you hear about that new invention?

Yeah, but I think it's unpatentable because it's based on existing technology.

That's a bummer! I thought it had a lot of potential.

It does, but without a unique twist, it can't be patented.

Root Explanation

Unpatentable → It is formed from "un-" (meaning not), "patent" (from Latin "patere", meaning to lie open or be evident), and "-able" (meaning capable of). The word "unpatentable" means not capable of being patented or not able to be made into a patent.

Memory Tip

Think of 'not' ('un-') being added to something that is 'open' or 'evident' ('patent') and 'capable' ('-able') — this helps you remember that unpatentable refers to something that cannot be made into a patent.
