DELMENDO, BEVERLY A. FRANKLIN, and GEORGE C. BEST, Administrative Patent Judges. FRANKLIN, Administrative Patent Judge. DECISION ON APPEAL Appellants appeal under 35 U.S.C. § 134 from the Examiner’s rejection of claims 22-36. We have jurisdiction under 35 U.S.C. § 6. STATEMENT OF THE CASE Claim 22 is representative of the subject matter on appeal and is set forth below, with emphasis added in italics: 22. A luminescence sensor comprising: Appeal 2011-012034 Application 11/917,947 2 - a region for containing a medium which comprises a plurality of luminescent particles, - a sensor, - an excitation radiation source for producing an excitation radiation and a detector being located respectively at opposite sides of the sensor for detecting luminescence radiation that may be generated by at least one of the luminescent particles, the sensor comprising a substrate, having at least one aperture or slit which is in communication with said region so that at least one luminescent particle of the medium can enter in said aperture or slit, and which has a smallest dimension below the diffraction limit in the medium for producing, when illuminated by said excitation radiation, an evanescent excitation volume which is able to excite in the aperture or slit the at least one luminescent particles which has entered. The prior art relied upon by the Examiner in rejecting the claims on appeal is: Nilsen et al. US 6,356,389 B1 Mar. 12, 2002 Fleming US 6,503,409 B1 Jan. 7, 2003 Kuroda et al. US 2003/0132392 A1 Jul. 17, 2003 Nikolov et al. US 2004/0095637 A1 May 20, 2004 THE REJECTIONS 1. Claims 22-25, 27-30, and 33-36 are rejected under 35 U.S.C. § 103(a) as unpatentable over Kuroda. 2. Claim 26 is rejected under 35 U.S.C. § 103(a) as unpatentable over Kuroda as applied to claim 25 above, and further in view of Fleming. 3. Claim 31 is rejected under 35 U.S.C. § 103(a) as unpatentable over Kuroda as applied to claim 22 above, and further in view of Nikolov. 4. Claim 32 is rejected under 35 U.S.C. § 103(a) as unpatentable over Kuroda and Nikolov as applied to claim 31 above, and further in view of Nilsen. Appeal 2011-012034 Application 11/917,947 3 ANALYSIS Issue: Did the Examiner err in determining that Kuroda suggests the claimed subject matter, in particular, the claimed subject matter of claim 22 pertaining to a luminescence sensor comprising, inter alia, an aperture or slit “which has a smallest dimension below the diffraction limit in the medium for producing, when illuminated by said excitation radiation, an evanescent excitation volume which is able to excite in the aperture or slit the at least one luminescent particles which has entered”? We answer this question in the negative and AFFIRM. Appellants argue that the Examiner has not considered all of the claimed elements in making the rejection. Br. 7. Appellants further argue that Kuroda does not disclose a value of the size of the slit that is a dimension below the diffraction limit in the medium. Br. 8; see also Reply Br. 1-5. We are unpersuaded of error in the Examiner’s rejections, by such argument, for the following reasons. First, as the Examiner points out on pages 9-10 of the Answer, he has considered the functional language of “for producing, when illuminated by said excitation radiation, an evanescent excitation volume which is able to excite in the aperture or slit the at least one luminescent particles which has entered,” and correctly explains how this language is met by the reference of Kuroda because Appellants’ claims are directed to an apparatus, and because Kuroda discloses the same structure (for the reasons expressed therein), as emphasized below. The Examiner finds that Kuroda teaches a width of the slit in the x direction as being in the range of from 1 - 200 nm. Kuroda, ¶ [0029]; Ans. 3. As such, the Examiner states that, in any medium having an index of Appeal 2011-012034 Application 11/917,947 4 refraction “from 1 to at least 5,” the dimension described in Kuroda would satisfy the claim’s limitation of a slit having a smallest dimension below the diffraction limit in the medium. Ans. 10-11. Appellants do not dispute this specific statement made by the Examiner. See Brief and Reply Brief generally. Most importantly, the Examiner explains that claim 22 is directed to an apparatus claim, and as such, because Kuroda’s luminescence sensor has the same structure as claimed by Appellants (for the reasons provided by the Examiner in his statement of the rejection made on page 3 of the Answer, e.g.), Kuroda’s luminescence sensor is capable of performing the claimed function, and therefore suggests the claimed subject matter. We agree. “[A]pparatus claims cover what a device is, not what a device does.” Hewlett-Packard Co. v. Bausch & Lomb, Inc., 909 F.2d 1464, 1468 (Fed. Cir. 1990). Therefore, the patentability of an apparatus claim depends on the claimed structure, not on the use or purpose of that structure, Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 809 (Fed. Cir. 2002), or the function or result of that structure, In re Danly, 263 F.2d 844, 848 (CCPA 1959); In re Gardiner, 171 F.2d 313, 315-16 (CCPA 1949). If the prior art structure possesses all the claimed characteristics including the capability of performing the claimed function, then there is a prima facie case of unpatentability. See, e.g., In re Schreiber, 128 F.3d 1473, 1478 (Fed. Cir. 1997) (Where there is reason to conclude that the structure of the prior art is inherently capable of performing the claimed function, the burden shifts to the applicant to show that the claimed function patentably distinguishes the claimed structure from the prior art structure.). Appeal 2011-012034 Application 11/917,947 5 Implicit in the aforementioned position of the Examiner is that a medium that enters the slit constitutes the material on which the luminescence sensor performs work, and thus, does not confer a patentable limitation on the claimed luminescence sensor. We agree. See, e.g., In re Otto, 312 F.2d 937, 939-40 (CCPA 1963); In re Rishoi, 197 F.2d 342, 344- 45 (CCPA 1952) (“[T]here is no patentable combination between a device and the material upon which it works.”); In re Young, 75 F.2d 996 (CCPA 1935); In re Smith, 36 F.2d 302, 303 (CCPA 1929) (“It might be argued that the invention here consists in a combination of extra length carbons with the old machine, and that such a combination is patentable. It will be borne in mind that it has been long established that a person may not patent a combination of device and material upon which the device works, nor limit other persons from the use of similar material by claiming a device patent.”). In view of the above, we therefore affirm Rejection 1. Because Appellants rely upon similar arguments for the other rejections (Br. 10-11), we also affirm Rejections 2-4 for the same reasons discussed above. The decision of the Examiner is affirmed. CONCLUSION OF LAW AND DECISION Each rejection is affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1).
