I Invented a Box Containing Hot Air: Shoot the Moon or File 13?
Similar to the public’s verdict about 1800s’ snake oil salesmen, the colloquialism “selling hot air” generally voices a negative connotation. But until Congress changes Title 35 of the U.S. Code, the ultimate arbiters of patentability are statutory requirements—not public opinion.
To understand how the United States Patent and Trademark Office (USPTO) evaluates an invention, let’s look at four different examples of “a box” to see what lands in the trash can (File 13) and what gets a shot at a patent (Shoot the Moon).
-
The Unpatentable Box
The Setup: A sealed cardboard box containing nothing other than ambient air at 100 degrees Fahrenheit.
The Verdict: High probability of File 13.
Standard cardboard boxes have been available for hundreds of years, and the statutes dictate that Natural Phenomena—such as ambient air—are not patentable. Simply trapping hot air in a standard container doesn’t cut it.
-
The “Something Different”
The Setup: An open-close box containing air, a cushion liner on the inside of the box, and a location tracker.
The Verdict: Possible, but likely File 13.
Under some narrow circumstances, this might be patentable if it features a brand-new location tracker that measures travel speed and position connected to the Cloud. However, there are already numerous tracking devices used by international carriers to move boxes around the globe. Without an additional search of the prior art, this one faces a steep uphill battle.
-
The Box with Internal Climate Control
The Setup: On the outside, it looks like a standard cardboard box that can be opened, closed, and sealed (cardboard is a cheap insulator). On the inside, the ambient air is actively controlled by a thermal heating and cooling system built into the inner liner. Along with a small vent, the box includes a microcontroller/processor, a mini-heat pump, a voltage supply, a temperature sensor, and tracking module circuitry with a transceiver connected to the Cloud.
The Verdict: High probability of Shoot the Moon!
It’s an integrated system. You aren’t patenting the air or the cardboard; you are potential a novel, man-made utility system that manipulates the internal environment.
-
A Very Soft Malleable Blanket
The Setup: On the outside, a durable, protective shell capable of absorbing extreme external shock. On the inside is a harvested donor heart traveling 400-plus miles to a waiting patient. The heart rests in a sterilized, malleable blanket that conforms to its exact shape, preventing it from contacting anything else. The box’s vent includes a microfilter to block pathogens. Alongside the processor, mini-heat pump, voltage supply, and Cloud transceiver, the box includes a supply of saline, a mini-fluid pump, and a layer of graphene contacting each millimeter of the heart’s external surface area.
The Verdict: Ultimate Shoot the Moon!
This is a highly sophisticated, life-saving apparatus with clear, markedly different structural and functional characteristics from anything found in nature. (Note: While highly patentable, you will definitely need FDA certification before introducing it into commerce!)
The Takeaway
Never assume your idea is too simple or too strange to be patentable. As humans, we often lean toward keeping the old rather than embracing the new. We weren’t there, but based on human nature, when the first person put a wheel on a peg, his peers likely laughed at him.
Ironically, we recently watched a documentary about the ten greatest inventions in human history. The wheel did not make the top 10. Something doesn’t seem quite right about that!
At the end of the day, some of the most valuable innovations look like “hot air” to the public until a granted patent proves otherwise.
