5.53 A claim should not use a relative term such as “thin”, “wide”, “strong” and the like unless the term has a well-recognized meaning in the particular art, for example “highfrequency” in relation to an amplifier, and this is the meaning intended.
5.54 If a relative term appears in a claim, the Examiner should consider whether the skilled person would be able to determine the scope of the claim either by following a standard disclosed in the description for measuring the degree of that relative term or in view of the common general knowledge in the art. However, even if a standard (for example an ISO-type standard) is provided, this may not provide sufficient clarity since different international standards may exist, or such standards can change over time.
