In "University of London Press Ltd v University Tutorial Press Ltd", the question arose as to whether certain mathematics exam papers were original literary works. The exam papers just consisted of conventional maths problems in a conventional manner. The court held that originality does not mean that the work must be an expression of individual thought. The simple fact that the authors drew on a body of knowledge common to mathematicians did not compromise originality. The requirement of originality, it was held, does not require that expression be in an original or novel form. It does, however, require that the work not be copied from another work. It must originate from the author.
