PTOL-90A (Rev. 04/07) UNITED STATES PATENT AND TRADEMARK OFFICE BEFORE THE PATENT TRIAL AND APPEAL BOARD Ex parte OCULUS OPTIKGERAETE, GmbH Patent Owner and Appellant Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 Technology Center 3900 Before DENISE M. POTHIER, ANDREW J. DILLON, and JENNIFER L. McKEOWN, Administrative Patent Judges. DILLON, Administrative Patent Judge DECISION ON APPEAL STATEMENT OF THE CASE This proceeding arose out of a request by Oculus Optikgeraete, GmbH (“Patent Owner”) for supplemental examination of U.S. Patent No. 6,212,006 B1 (“the ’006 patent”) to Josef Reiner, entitled Stereoscopic Microscope, issued April 3, 2001, and assigned to Oculus Optikgeraete, GmbH. Patent Owner appeals under 35 U.S.C. §§ 134 and 306 from the Examiner’s rejection of claims 2 and 4—20. Claims 1 and 3 have been Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 cancelled; claims 2, 4, 5, 10, and 15 were amended; claims 16—20 were added. App. Br. 3. We have jurisdiction under 35 U.S.C. § 6(b). The disclosed invention relates generally to a stereoscopic microscope which includes a binocular eyepiece arrangement, a binocular magnification changer, and a monocular lens arrangement. A reversal lens system can be inserted into beam paths in front of or behind the magnification changer, whereby it exchanges the two beam paths against one another and at the same time causes an image reversal. Spec 1:4—13. Amended independent claim 2 reads as follows: 2. A stereoscopic microscope comprising: a binocular lens arrangement, a binocular magnification changer, a monocular lens arrangement, and a movable reversal lens system for selective insertion into two beam paths in front of or behind the magnification changer, the reversal lens system exchanging the two beam paths against one another and causing at the same time an image reversal, the improvement comprising a supplementary lens for selective insertion or movement into an input beam path on an input side of the lens arrangement, and an optic system for selective insertion into the input beam path between the supplementary lens and an eye being tested for wide-angle viewing of a retina, the supplementary lens comprising a convex lens having a focal length being chosen or preselected so that the retina is viewable through the supplementary lens and the optic system of the microscope, while the lens arrangement of the microscope is focused on the cornea, wherein the reversal lens system and the supplementary lens are coupled with one another at least one of mechanically or electromechanically so that the reversal lens system and the supplementary lens are capable of simultaneous insertion into the beam paths and the input beam path, respectively. 2 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 REJECTIONS The following rejections are disputed by Patent Owner (App. Br. 6): 1. The Examiner rejects claims 4—9, 11—15, 18, and 20 under 35 U.S.C. § 112, second paragraph, as indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor regards as the invention. Final Act. 7—10. 2. The Examiner rejects independent claims 2, 4, 8, 10, and 15 under 35 U.S.C. § 103(a), as obvious in view of various combinations of U.S. Patent 3,799,645, Mar. 26, 1974 (“Stankewitz”) with one or more of Optical Technology Sales Literature entitled “SDI and BIOM” (1985) (“OTS Literature”); Admitted Prior Art (“APA”); M. Spitznas and J. Reiner, A Stereoscopic Diagonal Inverter (SDI) For Wide-Angle Vitreous Surgery, Graefe's Arch. Clin. Exp. Ophthalmology. (1987) 225:9-12 (“SDI Paper”); Manfred Spitznas, A Binocular Indirect Ophthalmomicroscope (BIOM) For Non-Contact Wide-Angle Vitreous Surgery, Graefe's Arch. Clin. Exp. Ophthalmology (1987) 225:13-15 (“the BIOM Paper”) (collectively, “The Stereoscopic Art.”) Final Act. 17—19, 21—35, 47—61. 3 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 ANALYSIS We have reviewed the Examiner’s rejections in light of Patent Owner’s contentions (App. Br. 6—14; Reply Br. 1—4) that the Examiner has erred. We have also reviewed the findings and reasons set forth by the Examiner in (1) the action from which this appeal is taken (Final Act. 2— 141), and (2) the reasons set forth by the Examiner in the Examiner’s Answer in response to Patent Owner’s Appeal Brief (Ans. 2—27). We highlight and amplify certain teachings and suggestions of the references as follows. §112 Second Paragraph Rejection The Examiner rejects claims 4—9, 11—15, 18, and 20 under 35 U.S.C. §112, second paragraph, as indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor regards as the invention. As a preliminary matter, the Examiner determines that Patent Owner did not invoke 35 U.S.C. §112, sixth paragraph for claims 2 and 4—20, which includes the claims rejected under 35 U.S.C. § 112. Specifically, the Examiner found that Patent Owner failed to utilize the term “means” or “step,” and further that the claims fail prong (A) as set forth in MPEP §2181 (I), which discusses whether the claims recite sufficiently definite structure for performing the claimed structure. See Final Act. 6. 4 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 In particular, with respect to claim 4, the Examiner finds that the phrase “wherein upon removal of the optic system from the beam path, the reversal lens system is withdrawn from the beam path upon insertion of the supplemental lens into the beam path” include indefinite functional language. Final Act. 8. Regarding claim 5, the Examiner finds the phrase “wherein, said insertable optic system being disposed in the input beam path when said movable supplementary lens moves out of said input beam path, and said movable supplementary lens being movable into said input beam path when said insertable optic system is out of said input beam path” include indefinite functional language. Id. Finally, with regard to claim 15, the Examiner also finds the phrase “wherein upon removal of the optic system from the beam path, the reversal lens system is withdrawn from the beam path upon insertion of the supplemental lens into the beam path” include indefinite functional language. Id. Specifically, the Examiner notes that claims 4, 5, and 15 each recite a “stereoscopic microscope” as well as various physical structures, e.g. “a reversal lens system.” Final Act. 9. The Examiner finds that one of ordinary skill in the art would conclude that these claims are product claims and would not be able to reasonably determine what structures are being referred to by the phrases rejected and set forth above (i.e., the discussed “Lens Switching Functions”). Id.', January 9, 2015 Advisory Act. 8. 5 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 Consequently, the Examiner finds that the aforementioned phrases render those claims indefinite under 35 U.S.C. §112, second paragraph because the boundaries of the claim scope are not clear. See Final Act. 9—10. Patent Owner argues that claims 4, 5, and 15 each specifically recite a coupling between the “supplementary lens” and the “lens reversal system” and consequently, these claims are definite. Patent Owner further contends that claims 4, 8, and 15 each functionally correlate the insertion of the optic system with the reversal system and corresponding lens. Patent Owner makes no separate arguments with regard to the claims which depend from claims 4, 5, and 15. App. Br. 13—14; Reply Br. 3^4. We find no error in the Examiner’s position. The mere coupling between the “supplementary lens” and the “lens reversal system” does not, in our opinion, address the Examiner’s concerns related to the scope of the claims’ “Lens Switching” function or provide the requisite structure to insert or withdraw one lens system into or out of the beam path, in relation to the movement of the other lens system, as claimed. We find the coupling between two lens systems, while an important element of the claimed functions, fails to recite any mechanism or structure for inserting or removing one lens system in relation to the movement of the other lens system and thus the scope of structure covered by the recited claims is unclear. Moreover, if Patent Owner is attempting to recite method steps within an apparatus claims of claims 4, 5, and 15, the claims are equally indefinite. 6 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 SeelPXL Holdings, LLC v. Amazon.com, Inc., 430 F.3d 1377, 1384 (Fed. Cir. 2005) Consequently, we determine the Examiner did not err in rejecting claims 4, 5, and 15, and dependent claims 6—9, 11—14, 18, and 20 under 35 U.S.C. § 112, second paragraph, as indefinite. Rejections Under 35 U.S.C. § 103(a) Patent Owner argues the Examiner erred in rejecting claims 2, 4, 8, 10, and 15 as obvious in view of various combinations of Stankewitz and multiple publications referred to collectively herein as “The Stereoscopic Art.” The bases for Patent Owner’s assertions are: Stankewitz fails to disclose coupling a reversal system with a supplementary lens; Stankewitz does not teach or suggest alternate insertion of a dispersion lens and other optical elements as recited in claim 4; there is no logical reason to combine Stankewitz with the Stereoscopic Art; and, Stankewitz is not analogous art to the Stereoscopic Art, rendering the proposed combination improper. We note Patent Owner similarly argues these points for claims 7 and 9; however, the Examiner did not reject claims 7 and 9 over this disputed combination of references (e.g., Stankewitz). Consequently, we do not address these arguments further for claims 7 and 9. Appeal Br. 8—13; Reply Br. 1—3. In response the Examiner points out that in the original request for Supplemental Examination, Patent Owner submitted a declaration by Rainer Kirchhubel, Managing Director of Oculus Optikgeraete GmbH. Ans. 3; 7 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 Final Act. 3. In that declaration Mr. Kirchhiibel stated that the distinction between the claimed invention and the Stereoscopic Art was “the novel feature of coupling the reversal lens system and supplementary lens together . . . Kirchhiibel Decl. Under Rule 1.132, paragraph 11. In light of the admission by Patent Owner’s Managing Director that the novel distinction between the Stereoscopic Art and the claimed invention was the coupling of lens systems, the Examiner merely cited Stankewitz to demonstrate that the coupling of lens systems was obvious, given the disclosure of a reversal lens, supplementary lens and removable insertable optic system within the Stereoscopic Art. Ans. 5—7. With respect to Patent Owner’s arguments above regarding Stankewitz failure to disclose particular combinations of lens systems which are coupled together (see App. Br. 8—10), we find that Patent Owner has attacked the Stankewitz reference individually, rather than considering what Stankewitz suggests when viewed in combination with the other cited references. “The test for obviousness is not whether . . . the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981) (citations omitted). “Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of references.” In re Merck & Co., 800 F.2d 8 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 1091, 1097 (Fed. Cir. 1986) (citing Keller, 642 F.2d at 425). In determining obviousness, furthermore, a reference “must be read, not in isolation, but for what it fairly teaches in combination with the prior art as a whole.” Id. In view of Patent Owner’s admissions regarding the elements disclosed by the Stereoscopic Art, we find the teaching by Stankewitz that various lens systems may be mechanically coupled together does indeed render obvious the claimed invention, as set forth in independent claims 2, 4, 10, and 15, and dependent claim 8. With regard to Patent Owner’s arguments regarding a logical reason to combine Stankewitz with the Stereoscopic Art, and the alleged non- analogous nature of Stankewitz (see App. Br. 10-13), the Examiner finds that Stankewitz discloses an illumination system for use with microscopes, and is thus, in the same field of endeavor as the Stereoscopic Art. See Stankewitz, Title. Further, the Examiner finds that Stankewitz describes “adapting to different objectives” (col. 1,11.11—19) which is described as “exchanging condenser lenses.” Ans. 16—18. The Examiner notes that Stankewitz discusses moving and positioning lenses, and the Stereoscopic Art also discusses microscopes with moveable lenses. The Examiner finds that a person of ordinary skill in the art has the skill set to appreciate both Stankewitz and the Stereoscopic Art, and Stankewitz is analogous art to the Stereoscopic Art, given the common teaching of microscopes and interchangeable lenses. Ans. 19—22. 9 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 We agree with the Examiner. We find that Stankewitz is analogous art, given the common teaching of microscopes and moveable lenses. Further, we determine that one of ordinary skill in the art, upon review of Stankewitz and the Stereoscopic Art, would find the mechanical coupling of various lenses to be an obvious modification of the Stereoscopic Art for the reasons set forth by the Examiner. See Ans. 6 (citing Stankewitz 1:5—10, 2:62-3:18). Accordingly, we determine the Examiner did not err in rejecting claims 2, 4, 8, 10, and 15 under 35 U.S.C. § 103. Reamining Rejections Under 35 U.S.C. §§ 102 and 103 As for the remaining pending rejections not disputed in the Final Action, Patent Owner did not argue these rejections and we find no evidence in the record that following the amendment to the claims the Examiner withdrew these rejections. Accordingly we summarily sustain the remaining rejections under 35 U.S.C. §§102 or 103. The Examiner has rejected claim 5 under 35 U.S.C. § 102(b) as anticipated by Optical Technology Sales Literature entitled "SDI and BIOM" (1985) ("OTS Literature"). Final Act. 10. Patent Owner did not argue this rejection ,and we find no evidence in the record that following the amendment to claim 5 the Examiner withdrew the rejection or substituted a 10 Appeal 2015-008322 Reexamination Control 96/000,057 Patent 6,212,006 B1 rejection under 35 U.S.C. § 103(a) in the manner applied to independent claims 2, 4, 10, and 15. Accordingly we summarily sustain the rejection of claim 5 under 35 U.S.C. § 102(b). In the alternative, if the Examiner intended to substitute a rejection of claim 5 under 35 U.S.C. § 103(a), as applied above, we would affirm that rejection for the reasons we set forth above. CONCLUSION We find no error in the Examiner’s rejection of claims 2 and 4—20. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). AFFIRMED 11 Copy with citationCopy as parenthetical citation
