“The term ‘person skilled in the art …’ has been interpreted to mean a person having ordinary or fair information in that particular line, not necessarily a person of high scientific attainments. The skill or knowledge to be imputed to such a person will vary with the complexity of the art to which the invention relates.” Archie R. McCrady, Patent Office Practice 61 (2d ed. 1946).
person with ordinary skill in the art
