04.07.09


Although granted patents are deemed useful, many of them don't seem that useful at all, including a sensor that detects whether you've hit a pedestrian and a clock that tells time in dog years.

</td></tr></tbody></table> <!-- End Buzz Block --> A patent for an invention is the grant of a property right to the inventor, issued by the United States Patent and Trademark Office (http://www.uspto.gov/index.html). Anyone who comes up with a new idea, or an improvement of an existing entity, should have that idea patented. You are, after all, competing with hundreds of thousands of likeminded individuals who just may invent the same thing you have.

Since 1963, the United States Patent and Trademark Office (http://www.pcmag.com/topic/0,2944,t=US%20Patent%20and%20Trademark%20Office&s=27523,00.asp) has granted more than 2.5 million utility (technology) patents in the U.S., which are issued for "the invention of a new and useful process, machine, manufacture, or composition of matter, or a new and useful improvement thereof." An issued patent generally prohibits others from making, using, or selling the invention for a period of up to twenty years from the date of patent application filing. Although granted patents are deemed useful, most of the ones we encountered through Google Patent Search (http://www.google.com/patents) don't seem that useful at all, including a sensor that detects whether you've hit a pedestrian and a clock that tells time in dog years. Here are ten of the strangest tech patents to ever have been issued.

Invention: Conductivity sensing device for diapers (http://www.google.com/patents?id=xPAvAAAAEBAJ&dq=4205672)
Patent number: 4205672
Filing date: Nov 28, 1977
Issue date: Jun 3, 1980
Inventor: Karel Dvorak
Instead of relying on your sense of smell to indicate whether your baby's diapers need changing, this invention consists of a device that senses dampness in a diaper for you. The diaper will have a plastic waterproof outer layer and an inner layer of urine-absorbent material, while the sensing device will comprise of a pair of electric "connected jaw members" that clamp on the edge of a disposable diaper and detect a change of conductivity within the diapers.
