What can be patented?
Utility patents protect inventions that are a novel, nonobvious, and usefulUtility patents
Utility patents are for either a: process, machine, article of manufacture, composition of matter or an improvement of any of the above. Patent protection is also available for (1) ornamental design of an article of manufacture (design patent) or (2) asexually reproduced plant varieties by design and plant patents (plant patent).Different Ways To Patent Search For Inventions
Here are three tutorials on the three basic ways to conduct a patent search. Remember these are introductory tutorials, and not a substitute for an advanced or professional patent search. Patent Search by Patent Number: This is the easiest way to find out about an invention! Patent Search by the Inventor's Name: This sometimes requires a little detective work, but you can do it! Patent Search Using Words: This is the most challenging and fun way to look for inventions!How long does patent protection last? (As of year 2005)
Utility and plant patents are granted for a term which begins with the date of the grant and usually ends 20 years from the date the applications were filed. You must make the timely payment of the appropriate maintenance fees. Design patents last 14 years from the date you are granted the patent. No maintenance fees are required for design patents.Why is classification so important?
While it is possible to search patents using keywords, the best way to conduct a comprehensive patent search is by classification. Classification helps bring together similar devices and concepts, even when different terms have been used to describe them. When a device is truly new, terminology is not set. For example, before personal computers a mouse was nothing more than a rodent. The inventor of the first "Computer Input and Display Control" would not have found related devices by searching the keyword "mouse." A classification is used both as a tool for finding patents (patentability searches), and for assisting in the assignment of patent applications to examiners for examination purposes. Classifications have definitions. Classifications have hierarchical relationships to one another.
