¶ 7.34.04 Broader Range/Limitation And Narrow Range/Limitation in Same Claim
A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) is considered indefinite, since the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). Note the explanation given by the Board of Patent Appeals and Interferences in Ex parte Wu, 10 USPQ2d 2031, 2033 (Bd. Pat. App. & Inter. 1989), as to where broad language is followed by "such as" and then narrow language. The Board stated that this can render a claim indefinite by raising a question or doubt as to whether the feature introduced by such language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Note also, for example, the decisions of Ex parte Steigewald, 131 USPQ 74 (Bd. App. 1961); Ex parte Hall, 83 USPQ 38 (Bd. App. 1948); and Ex parte Hasche, 86 USPQ 481 (Bd. App. 1949). In the present instance, claim [1] recites the broad recitation [2], and the claim also recites [3] which is the narrower statement of the range/limitation.
Examiner Note:
1. In bracket 2, insert the broader range/limitation and where it appears in the claim; in bracket 3, insert the narrow range/limitation and where it appears. This form paragraph may be modified to fit other instances of indefiniteness in the claims.
2. This form paragraph must be preceded by form paragraph 7.34.01.
