Invention and Art Analogy

For a patent attorney, working with a patent examiner to prove to the examiner that an invention created by an inventor is patentable. the challenge is, in a sense, similar to a challenge an artist often faces. 

For example, when looking at a rough rock, a layperson may see just that, a rough rock; however, an artist sees past the rough edges of the rock; he sees a beautiful sculpture lying inside that rock. 

Similarly, when a patent examiner sees an invention as being, for example, a simple and obvious assembly of known parts, it is the challenge, and duty, of the patent attorney to help the patent examiner see the beautiful invention that lies inside, the spark of genius, the discovery that led the inventor to that invention, and therefore, of course, why the inventor should be rewarded with a patent.
