Qualifying for a Patent
A patent is a document issued by the U.S. Patent and Trademark Office (PTO) that grants a monopoly for a limited period of time on the manufacture, use, and sale of an invention. These exclusive rights last between 14 and 20 years, depending on the type of invention.
What types of inventions can be patented?
The PTO issues three different kinds of patents: utility patents, design patents, and plant patents.
To qualify for a utility patent -- by far the most common type -- an invention must be:
Often, an invention will fall into more than one category. For instance, a laser can usually be described as both a process (the steps necessary to produce the laser beam) and a machine (a device that implements the steps to produce the laser beam). Regardless of the number of categories into which a particular invention fits, it can receive only one utility patent.
If an invention fits into one of the categories described above, it is known as "statutory subject matter" and has passed the first test in qualifying for a patent. But an inventor's creation must overcome several additional hurdles before the PTO will issue a patent. The invention must also:
For design patents, the law requires that the design be novel, nonobvious, and nonfunctional. For example, a new shape for a car fender, bottle, or flashlight that doesn't improve its functionality would qualify.
Finally, plants may qualify for a patent if they are both novel and nonobvious. Plant patents are issued less frequently than any other type of patent.
