What does unpatented mean?
Unpatented is an adjective describing an invention, process, product, substance, or other subject that is not covered by a patent. A patent normally grants its holder the right to exclude others from making, using, or selling the protected subject for a limited period; saying that something is unpatented means that no such right is being asserted. The word is especially common in medicine, chemistry, engineering, and business, where a formula, treatment, tool, or process may remain freely usable. It does not imply that the subject is ineffective, unlawful, inferior, or newly invented. Nor does it mean that no other form of protection may exist: confidential know-how might instead be guarded as a trade secret, and copyright can cover expressive material such as software code or documentation. Unpatented is a technical and legal term but is readily understood by general readers. It is useful because it distinguishes the legal status of an idea or invention from its quality, usefulness, or commercial value.
adjectiveNot protected by a patent; not covered by an exclusive patent right. The term can also indicate that no patent has been obtained for an invention, process, product, or substance.
- Not protected or covered by a patent.
"The herbal remedy remains unpatented, so its manufacturer cannot exclude competitors from selling it."
"The researchers published their findings as an unpatented process so that other laboratories could reproduce it."
"The company shelved its unpatented prototype in favor of applying for a patent."
An innovation can be protected as a trade secret, but calling it unpatented means the patent system itself is not protecting it.

Where does unpatented come from?
Unpatented was formed in English by attaching the prefix un- to patent, a word borrowed through Old French from Latin patentem, meaning “open” or “accessible to all,” a participial form of patere, “to be open.” Its ultimate Latin relatives include patient, from pati, “to suffer,” and compatible and sympathy, whose Latin and Greek formations likewise involve suffering or enduring.
How unpatented is actually used
Neutral in connotation and used chiefly in legal, scientific, industrial, and commercial contexts. It describes patent status rather than quality, effectiveness, or commercial value.
