Infringement is the uses of ideas, products, or components of a patented item for sale within another product. “A person, other than a patent owner, infringes a patent when he offers for sale or supplies products that constitute essential elements of an invention to parties unauthorized to use such invention” (.FiÅ¡er-Å obot, 2010 p 12).
According to the Encarta Dictionary, to infringe is simply to disobey or disregard something. In the following cases however, “if the offerer or supplier knows or has demonstrable grounds to know that such products are intended for the use of an invention owned by somebody else. This is called indirect infringement of a patent” (FiÅ¡er-Å obot, 2010 p 12).
