PAK, CHARES F. WARREN, and PETER F. KRATZ, Administrative Patent Judges. KRATZ, Administrative Patent Judge. DECISION ON APPEAL1 This is a decision on an appeal under 35 U.S.C. § 134 from the Examiner’s final rejection of claims 1-3 and 5-8. We have jurisdiction pursuant to 35 U.S.C. § 6. 1 The two-month time period for filing an appeal or commencing a civil action, as recited in 37 C.F.R. § 1.304, or for filing a request for rehearing, as recited in 37 C.F.R. § 41.52, begins to run from the “MAIL DATE” (paper delivery mode) or the “NOTIFICATION DATE” (electronic delivery mode) shown on the PTOL-90A cover letter attached to this decision. Appeal 2009-006919 Application 10/931,805 2 Appellants’ claimed invention is directed to a method of forming an inorganic alignment film. Appellants’ method provides an alignment film of inorganic material on a base substrate using a milling step of irradiating ion beams onto the base surface substrate on which the alignment film is to be formed (Spec. para. 0011). The method is said to be useful for providing o film having excellent light resistance with a suitably inclined surface (tilt angle) that is useful for regulating alignment properties of liquid crystal molecules of a liquid crystal panel used in electronic apparatus (Spec. paras. 0012 - 0043). Appellants apply an acceleration voltage of about 800 to 1400 Volts to the ion beams during the milling step irradiation (App. Br. 4-52). Claim 1, the sole independent claim on appeal, is illustrative and reproduced below: 1. A method of forming an inorganic alignment film made substantially of an inorganic material on a base substrate, comprising: a milling step of irradiating ion beams onto a surface of the base substrate, on which the inorganic alignment film is to be formed, from a direction inclined at a predetermined angle өb with respect to a direction vertical to the surface; and a film-forming step of forming the inorganic alignment film on the base substrate onto which the ion beams are irradiated, 2 Our references to the Appeal Brief (App. Br.) are to the Brief filed July 11, 2008 and our references to the Reply Brief (Reply Br.) are to the Reply Brief filed December 01, 2008. The Appeal Brief includes the page number 16 for all of the pages, except the first page. We apply our own numbers in referencing the Appeal Brief pages beginning with page 1 for the first page and continuing in numeric order. Appeal 2009-006919 Application 10/931,805 3 wherein in the milling step, an acceleration voltage of the ion beams during the irradiation of the ion beams is about 800 to about 1400 V. The Examiner relies on the following prior art references as evidence in rejecting the appealed claims: Little 4,152,529 May 9, 1979 Krueger 4,456,515 Jun. 26 1984 Shigeta 5,268,781 Dec. 1, 1993 Burke 5,658,439 Aug. 19, 1997 Callegari 6,061,114 May 8, 2000 The following rejections are maintained by the Examiner:3 3 The last three obviousness rejections pertaining to certain dependent claims appear in the Final Office Action (FOA) and have not been withdrawn by the Examiner (FOA 6-8; Ans.3-4). The Examiner contends that these latter rejections are grounds of rejection not to be reviewed on appeal. We disagree. A reading of the Appeal Brief and the Reply Brief, taken as a whole, reveals that Appellants are contesting all of the rejections pertaining to appealed dependent claims 5-8, albeit on the basis of features found in claim 1 that carry forward to these appealed dependent claims and arguments made with respect to the three rejections pertaining to independent claim 1 (App. Br. 1, 3, 5, 10, and 11; Reply Br. 2-4, and 7). This is made apparent by the fact that the only rejections maintained by the Examiner pertaining to dependent claims 7 and 8 are among the rejections that the Examiner contends are not subject to review on appeal. Yet, the rejections that pertain to these claims are contested by Appellants (App. Br. 10-11). In these dependent claim rejections, the Examiner applies additional reference(s) for the added features of the dependent claims; but, the Examiner otherwise relies on the same references employed in the separate rejections that pertain to independent claim 1 for asserting non-patentability of the claim 1 limitations imported into the dependent claims by their dependency status. Thus, Appellants’ argument against the Examiner’s obviousness rejections of the dependent claims, including claims 7 and 8, on the basis of the features argued for claim 1, puts the dependent claim rejections in contention on appeal (App. Br. 10-11). Appeal 2009-006919 Application 10/931,805 4 Claims 1-3 stand rejected under 35 U.S.C. § 102(b) as being anticipated by Little. Claims 1-3, 5, and 6 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Shigeta in view of Little. Claims 1-3 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Krueger in view of Little. Claims 5 and 6 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Krueger in view of Little and Shigeta. Claim 8 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Shigeta in view of Little, or Little, or Krueger in view of Little, each further in view of Callegari. Claim 7 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Shigeta in view of Little, or Little, or Krueger in view of Little, each further in view of Callegari and Burkle. We reverse the stated rejections for substantially the reasons set forth in the Appeal Brief and Reply Brief. The Examiner contends, as set forth initially in the anticipation rejection of claims 1-3, and as further relied on in all of the obviousness rejections, that the teaching of Little that “the voltage of the ion beam can be 1-3 kiloelectron volt” translates into a description of an ion beam voltage (1,000 – 3,000 Volts) that anticipates, or renders obvious under 35 U.S.C. § 103(a), the claimed “about 800 to about 1,400 V” milling step acceleration voltage limitation (Ans. 5-9; Little, col. 3, ll. 45-47). Concerning this same claim feature of independent claim 1, the Examiner further contends, with respect to the obviousness rejections employing Shigeta as evidence of obviousness, that the claimed acceleration voltage lower limit of “about 800” volts reads on the 500 volt ion beam disclosure found in Example 3 of Shigeta (Ans. 6, 8, 9; Shigeta, col. 4, l. 7). Appellants contend otherwise (App. Br. 8-11; Reply Br. 4-7). Appeal 2009-006919 Application 10/931,805 5 Consequently the dispositive issues in this appeal are: Has the Examiner established that Little describes a milling step of irradiating ion beams onto a base substrate surface, wherein “an acceleration voltage of the ion beams during the irradiation of the ion beams during the irradiation of the ion beams is about 800 to about 1400 V”, as recited in appealed claim 1. If not, with respect to the obviousness rejections that rely, in part, on Shigeta as evidence of obviousness, has the Examiner established that 500 volts is “about 800 volts” when claim 1 is given its broadest reasonable construction as it would be understood by one of ordinary skill in the art? We answer both questions in the negative. PRINCIPLES OF LAW "[T]he Examiner bears the initial burden, on review of the prior art or on any other ground, of presenting a prima facie case of unpatentability." In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). The factual determination of anticipation requires the disclosure in a single reference of every element of the claimed invention, either explicitly or inherently. See In re Schreiber, 128 F.3d 1473, 1477 (Fed. Cir. 1997). Establishing a prima facie case of obviousness of an invention requires “an apparent reason to combine the known elements in the fashion claimed.” KSR Int’l. Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Appeal 2009-006919 Application 10/931,805 6 FINDINGS OF FACT Appellants describe applying “[a]n acceleration voltage of ions” “to the leading out electrode M12” to accelerate the ions “such that ion beams are irradiated toward the base substrate 100” (Spec. para. 0099; Fig. 4). Little discloses a method and apparatus for inducing parallel alignment of liquid crystal material, wherein a beam of neutralized ions of a specified energy level are used to provide small streaks or grooves on an electrode surface (col. 1, ll. 43-52). Little discloses that “[t]he specific material of the ion beam may be any gas which will provide a scrubbing action. Such a gas is argon at an energy of 1-3 kilo-electron-volts” (col. 3, ll. 45-47). Little further discloses (col. 2, ll. 24-35; Figs. 1 and 2): The present invention includes a duoplasmatron ion source 12 having a gas inlet 14 of any suitable gas, preferably an inert gas, such as of argon, an electrode outlet 16 for directing ions formed from the gas toward a target, and a neutralizer 18, such as for maintaining the target electronically neutral, thereby for preventing the buildup of positive charges on the target. Because of the existence of electrons from neutralizer 18, the average charge density or space charge of the ion beam is also kept neutral. Shigeta discloses a method of producing a homeotropic-alignment liquid crystal display device wherein an ionized gas (oxygen) was used to irradiate a substrate surface having a silicon dioxide coating deposited thereon at an ion beam power of 500 V., 40 mA for two minutes prior to coating with a homeotropic alignment film. (col. 5, l. 63 – col. 6, l. 42). Appeal 2009-006919 Application 10/931,805 7 DISCUSSION Concerning the anticipation rejection of claims 1-3 over Little, the Examiner asserts that the disclosed 1-3 kilo-electron volt energy level of the argon ion beam of Little conveys a description of the claimed “about 800 to about 1400 V” acceleration voltage of the ion beams used in Appellants’ milling step. However, other than the simple conversion of kilo to one thousand, the Examiner has not carried the burden to establish that the argon beam energy level referred to by Little would be recognized by one of ordinary skill in the art as providing a description of Appellants’ method of using an acceleration voltage of about 800 to about 1400 volts (argued applied potential difference) for the ion beams used in the milling step of appealed claim 1. In this regard, it appears that the Examiner considers the energy level of the argon ion beam reported by Little, in kilo-electron volts, to be a measure, in kilo-volts, of an acceleration voltage applied by Little to achieve this argon ion beam energy level. However, the Examiner has not furnished any evidence to substantiate this assertion. Nor has the Examiner explained how the mass of the argon atoms/ions of the argon beam are taken into account in performing the Examiner’s proposed conversion of the disclosed ion beam energy levels of Little into an acceleration force or voltage applied, corresponding to that required by the method of claim 1. Looked at another way, while one electron volt may be a measure or indicator of the energy added to an electron by being drawn through a potential difference of one volt, the Examiner has not informed the appeal record of such with any evidence relied upon in the stated rejections, much less explained how the [total] energy of the neutralized argon beam Appeal 2009-006919 Application 10/931,805 8 employed by Little readily converts to a description of the claimed acceleration voltage. On this record, we are constrained to reverse the Examiner’s anticipation rejection, as well as the obviousness rejection of claims 1-3 over Krueger in view of Little, which likewise is founded on the Examiner’s unsubstantiated assertion that Little provides a description of the claimed acceleration voltage. Concerning the Examiner’s obviousness rejection of claims 1-3, 5, and 6 over Shigeta in view of Little, the Examiner additionally argues that the claimed acceleration voltage of about 800 to about 1400 volts reads on the disclosed 500 Volt disclosure of Shigeta (Ans. 6 and 8). However, as correctly argued by Appellants, the Examiner misconstrues the claim term “about 800” in asserting that 500 volts is about 800 volts (App. Br. 9; Reply Br. 6). The Examiner has not proffered a persuasive rationale to explain why it may have been obvious to one of ordinary skill in the art to increase the applied voltage of Shigeta for the irradiation of the silicon dioxide film of Shigeta to an acceleration voltage within the claimed range. On this record, we reverse the Examiner’s obviousness rejection over Shigeta in view of Little. Regarding the remaining obviousness rejections of several of the dependent claims, these rejections rely on the same reasoning and teachings of Shigeta and/or Little for allegedly teaching the acceleration voltage limitation imported into these claims by virtue of their dependency on claim 1. The additional applied references are not relied on by the Examiner for teaching or suggesting this claim feature. It follows that we shall likewise reverse the remaining obviousness rejections. Appeal 2009-006919 Application 10/931,805 9 CONCLUSION/ORDER The Examiner’s decision to reject claims 1-3 under 35 U.S.C. § 102(b) as being anticipated by Little; to reject claims 1-3, 5, and 6 under 35 U.S.C. § 103(a) as being unpatentable over Shigeta in view of Little; to reject claims 1-3 under 35 U.S.C. § 103(a) as being unpatentable over Krueger in view of Little; to reject claims 5 and 6 under 35 U.S.C. § 103(a) as being unpatentable over Krueger in view of Little and Shigeta; to reject claim 8 under 35 U.S.C. § 103(a) as being unpatentable over Shigeta in view of Little, or Little, or Krueger in view of Little, each further in view of Callegari; and to reject claim 7 under 35 U.S.C. § 103(a) as being unpatentable over Shigeta in view of Little, or Little, or Krueger in view of Little, each further in view of Callegari and Burkle is reversed.
