Parameters at the EPO – avoiding traps for the unwary
Products and processes in the chemistry and material science fields are often defined using parameters. Sometimes a parametric definition is the only way in which to define the property of a substance or in some cases the substance itself. For example, a new crystalline form of a compound is often defined with reference to peak values from an x-ray diffraction spectra. The viscosity of a liquid reactant may be critical to the performance of an industrial synthesis process.
