A video features a countdown of 13 strange and seemingly useless inventions that were patented. These include:
1. A centrifugal childbirth device using a net and a machine to rotate the woman, patented in 1965.
2. A "death star" - a weapon that runs on solar energy and orbits the Earth to launch a laser beam to destroy targets.
3. A graphical interface for a screen with a specific layout of rectangles and a square.
4. A wooden stick for dogs to play with, patented in 1999.
5. A device to stop stolen cars using a barcode, requiring all cars to have one.
6. A machine to kick users, patented in 2001 as an "entertainment device".
7. An automatic light bulb changer, which seems unnecessary and expensive.
8. A device to emit a beam of light for cats to chase, similar to a laser pointer.
9. A method to treat hiccups by drinking electrified water from a glass.
10. A system for making cockfights non-fatal by using protection on the roosters' legs.
11. An ear protector for dogs to prevent their ears from getting dirty while eating and drinking.
12. A "smoker's hat" that eliminates smoke and odor using integrated filters.
13. Two strange glasses inventions: one with piercings to hold the glasses in place, and another with subliminal images to improve the wearer's life.
The video questions the usefulness and practicality of these inventions, suggesting that some may have been patented solely for the purpose of filing lawsuits.
Here are the key facts extracted from the text:
1. There are over 500,000 patents filed each year.
2. The basis for patenting something is that it must be novel, obvious, and useful.
3. A device to facilitate childbirth using centrifugal force was patented in 1965 by the Brand Brothers.
4. The device was intended to make childbirth easier by using a machine to rotate the woman, rather than relying on her own efforts.
5. The device included a net to catch the baby and a contraption to prevent the woman's head from spinning.
6. A patent for a "death star" was filed by Ricky Martin, which was a solar-powered weapon that could orbit the Earth and launch a laser beam to destroy a city or ship.
7. The patent was compared to the Death Star from the Star Wars franchise.
8. A patent for a display portion of a screen with a graphical interface was filed, which included a design with three rectangles and a square underneath with an image.
9. A patent for a device to aid in childbirth was filed, which claimed to reduce stress on the mother.
10. A patent for a safe method to stop a stolen vehicle without a high-speed chase was filed, which used a barcode system to identify and stop the vehicle.
11. A patent for a device to kick you in the butt was filed in 2001, which was an entertainment device controlled by the user.
12. A patent for a light bulb changer was filed, which was supposed to automatically detect when a light bulb had blown out and change it on its own.
13. A patent for a device to emit a beam of light for a cat to chase was filed, which was essentially a laser pointer.
14. Multiple patents for the same idea of a laser pointer for pets were accepted.
15. A patent for a device to treat hiccups was filed, which involved drinking electrified water.
16. A patent for a system to make cockfights non-fatal was filed, which involved putting protection on the legs of the cocks.
17. An ear protector for dogs was patented, which was supposed to prevent the dog's ears from getting dirty while eating and drinking.
18. A smoking hat was patented, which was a portable system to smoke without harming others, using integrated filters to eliminate smoke and odor.
19. Glasses with piercings were patented, which were supposed to be more comfortable than wearing normal glasses.
20. Glasses with subliminal images were patented, which were supposed to improve the wearer's life by suggesting art with images.
