Etymology

From Latin patēre ('to lie open, be accessible'), via the past participle patens ('lying open'). The noun entered English through Anglo-French lettres patentes ('open letters') — royal grants addressed to the general public rather than a specific recipient, as opposed to lettres closes ('sealed/closed letters'). The IP noun and verb senses descend from this tradition of publicly declared exclusive grants. The adjective sense 'clearly obvious' is directly from the Latin root meaning 'open, evident'.

FAQ

What is a patent?

A patent is a government-granted exclusive right that allows an inventor to control who makes, uses, or sells their invention for a set period — typically 20 years. In exchange, the inventor publicly discloses how the invention works, adding it to the body of human knowledge.

What is the difference between a patent, copyright, and trademark?

A patent protects inventions (products and processes). A copyright protects original creative works such as books, music, and software code. A trademark protects brand identifiers such as names, logos, and slogans. They are three distinct branches of intellectual property law.

What does 'patent' mean as an adjective?

As a formal adjective, patent means plainly obvious or unmistakable — usually applied to something negative: 'a patent lie', 'patent nonsense', 'patent absurdity'. This sense comes directly from the Latin root meaning 'open, visible'.

Can you patent an idea or algorithm?

Generally no. Abstract ideas, mathematical formulas, and laws of nature cannot be patented in most jurisdictions. A specific technical implementation or application of an idea may be patentable, but the idea itself is not. Software patents are a complex and contested area.

What does 'patent pending' mean?

'Patent pending' means that a patent application has been filed but not yet granted. It puts competitors on notice that a patent may be issued and that retroactive damages could apply. It does not itself confer any legal rights.

Patent leather is its own everyday phrase. It means the shiny coated leather used for dress shoes, bags, etc. Nothing to do with patent nonsense or the obvious meaning when you see it in a shop.

Software is where the word gets messy. A code license and a patent license are not automatically the same thing, so open source people get nervous when an algorithm or method has a patent hanging over it.

Patent pending sounds stronger than it is. It means an application is on file, not that the patent office has agreed the invention deserves a patent. It can still be useful as a warning label, but it is not the same as having an issued patent.

yep, investors still ask what is actually allowed, not just pending

People say patent when they really mean any kind of IP all the time. A brand name is trademark, a song or photo is copyright, an invention or process might be patent. If someone says I patented my logo, they almost surely mean registered a trademark.
