Patents are valuable - Patents may have commercial value but that usually depends upon how it has been used. A patent means the invention works as verified by the government - The U.S. government does not test inventions to see if they work. A patent gives the owner the exclusive right to make, use, and sell the invention - A patent gives its owner the right to EXCLUDE others from making, using, and selling exactly what is covered by their patent claims. A holder of a prior patent with broader claims may prevent the inventor whose patent has narrower claims from using the inventor's own patent. A patent right is exclusory only.What is prior art?
Prior art is all information that has been disclosed to the public in any form about an invention before a given date. Prior art includes things like any patents related to your invention, any published articles about your invention, and any public demonstrations. prior art is "the total body of knowledge, which teaches or otherwise relates directly to an invention. This is the primary criteria in determining the patentability of a new invention. Establishes novelty and unobviousness of the art that relates to the invention in question. Prior art references include documentary sources such as patents and publications from anywhere in the world, and nondocumentary sources such as things known or used publicly."What Does Useful Mean?
The patent law specifies that inventions must be useful, which means have a useful purpose. Being useful also includes operativeness, meaning that an invention must operate or perform its intended purpose.
