6.3. Selection of parameter ranges

A claimed feature that an angle has a magnitude of "more than 0 degrees" does not establish novelty over a prior art disclosure in which the corresponding angle is equal to 0 degrees, since the feature encompasses values closer to 0 degrees than the finite error margin to which the determination of the magnitude of the angle would always be subject, and such values would, in practice, be indistinguishable from 0 degrees (see Reasons, point 2.8, confirming T 594/01).
