DECISION ON APPEAL STATEMENT OF THE CASE Appellants appeal under 35 U.S.C. § 134(a) from the Examiner’s final rejection of claims 1-14. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 Koninklijke Philips Electronics N.V. and Sharp Corporation are the real parties in interest. Appeal 2010-009034 Application 10/128,636 2 INVENTION Appellants’ invention relates to radio communication systems and further relates to primary and secondary stations for use in such systems and to methods of operating such systems. See generally Spec. 1:5-10. Claim 1 is illustrative and is reproduced below with disputed limitations emphasized: 1. A radio communication system having a communication channel comprising: a primary station having a plurality of antennas; a secondary station having at least one antenna; and a plurality of paths between the primary station and the secondary station, the primary station further comprising means for transmitting substantially simultaneously a plurality of data packets to the secondary station, each packet being transmitted via a different subset of the plurality of paths, and the secondary station further comprising means for receiving the plurality of data packets, for determining whether each packet is received correctly, for signaling this determination to the primary station for each of the plurality of packets, and for signaling to the primary station the number of simultaneous data streams that the secondary station is capable of receiving or processing independent of the transmission medium. The Examiner relies on the following as evidence of unpatentability: Tiedemann Wallace Wallace 146 Kogiantis US 2002/0154610 A1 US 6,473,467 B1 US 2002/0193146 A1 US 6,751,480 B2 Oct. 24, 2002 Oct. 29, 2002 Dec. 19, 2002 June 15, 2004 Appeal 2010-009034 Application 10/128,636 3 THE REJECTIONS 1. The Examiner rejected claims 1-7, 9, and 11-14 under 35 U.S.C. § 103(a) as unpatentable over Wallace, Kogiantis, and Wallace 146. Ans. 3-7.2 2. The Examiner rejected claims 8 and 10 under 35 U.S.C. § 103(a) as unpatentable over Wallace, Kogiantis, Wallace 146, and Tiedemann. Id. at 8-9. OBVIOUSNESS REJECTION OVER WALLACE, KOGIANTIS, AND WALLACE 146 Regarding representative claim 1, the Examiner finds that Wallace discloses all of the limitations of claim 1, except for means (1) “for determining whether each packet is received correctly,” (2) “for signaling this determination to the primary station for each of the plurality of packets,” and (3) “for signaling to the primary station the number of simultaneous data streams that the secondary station is capable of receiving or processing independent of the transmission medium.” Ans. 3-4. Nevertheless, the Examiner finds that the first and second missing limitations are disclosed by Kogiantis (id. at 5)3 and that the third missing limitation is disclosed by Wallace 146 (id. at 4-5). Moreover, the Examiner concludes that a person of ordinary skill in the relevant art would have reason to combine the teachings 2 Throughout this opinion, we refer to (1) the Appeal Brief (App. Br.) filed January 28, 2010; (2) the Examiner’s Answer (Ans.) mailed March 29, 2010; and (3) the Reply Brief (Reply Br.) filed June 1, 2010. 3 Appellants argue that Wallace 146 does not disclose or suggest that a mobile user comprises means for receiving the plurality of data packets or for determining and signaling whether each packet is correctly received. Reply Br. 4. We note that the Examiner relies on Wallace and Kogiantis, not Wallace 146, to disclose these limitations. Ans. 3-4. Appeal 2010-009034 Application 10/128,636 4 of these references to achieve the communications system, as recited in claim 1. Id. at 5. Appellants argue that Wallace 146 fails to disclose means “for signaling to the primary station the number of simultaneous data streams that the secondary station is capable of receiving or processing independent of the transmission medium.” App. Br. 8-9. Further, Appellants contend that Examiner fails to identify a reason for a person of ordinary skill in the relevant art to combine the teachings of Wallace, Kogiantis, and Wallace 146. Id. at 10. ISSUES (1) Under § 103, has the Examiner erred in rejecting claim 1 by finding that Wallace, Kogiantis, and Wallace 146, collectively, teach or suggest that “the secondary station further comprising means . . . for signaling to the primary station the number of simultaneous data streams that the secondary station is capable of receiving or processing independent of the transmission medium”? (2) Is the Examiner’s reason to combine the teachings of these references supported by articulated reasoning with some rational underpinning to justify the Examiner’s obviousness conclusion? ANALYSIS Based on the record before us, we discern no error in the Examiner’s rejection of representative claim 1 which calls for, in pertinent part, that “the secondary station further comprising means . . . for signaling to the primary station the number of simultaneous data streams that the secondary station is capable of receiving or processing independent of the transmission medium.” The Examiner finds that “Wallace 146 discloses determining an Appeal 2010-009034 Application 10/128,636 5 appropriate transmission scenario based upon the antenna diversity station of the base station and mobile station, signaling the number of respective receive antennas (corresponding to the number of streams capable of being received or processed at the same time) at each station.” Ans. 5 (citing Wallace 146, ¶ [0125]) (emphasis added); Final Rej. 3-4. Moreover, the Examiner finds that Wallace 146 discloses that the secondary station signals the number of simultaneous data streams that the secondary station is capable of receiving or processing. Ans. 5; Final Rej. 4. Referring to Figures 13 and 14, Wallace 146 describes that base station 900 performs various methods to determine an appropriate transmission scenario. Wallace 146, ¶ [0125]. In particular, Wallace 146 states that according to one embodiment, the method extracts antenna diversity status information from the other participant[, e.g., a mobile user,] to a communication. . . . For a given mobile user, the antenna diversity status may include the number of transmit antennas, the number of receive antennas, the reception diversity configuration, as well as other parameters of the mobile user. Id. (emphases added); see also Wallace 146, ¶¶ [0046]-[0047] (describing the use of multiple antennas at the receiver and the transmitter). In light of the above-noted teachings of Wallace 146, the Examiner concludes that the mobile user “signals” to the base station the number of antennas that the mobile user possesses, “the reception diversity configuration,4 as well as other parameters,” in response to an extracting query. Advisory Action 2 (citing Wallace 146, ¶ [0125]) (footnote added); see also Ans. 10-11. 4 See Wallace 146, ¶¶ [0074]-[0076] (describing methods of reception diversity). Appeal 2010-009034 Application 10/128,636 6 Referring to their Figure 4, Appellants describe transmitting a plurality of data packets from a primary station to a secondary station and determining and signaling whether those packets were correctly received, as recited in claim 1. Spec. 8:12-22. The described system is characterized as a “Multi-Input Multi-Output” or “MIMO” system. Id. at 1:30-2:2. Appellants state that A simple embodiment of a MIMO packet data transmission scheme operating in accordance with the present invention is shown in Figure 4. In this embodiment each data sub-stream is allocated a separate [Automatic Repeat request (ARQ)] channel, and the BS 100 and MS 110 each have two antennas 108,118. In the example shown, the BS 100 transmits two packets 302, P1 and P2, as part of respective downlink data sub-streams DL1 and DL2 transmitted from respective antennas 108. The packets 302 are transmitted substantially simultaneously. Id. at 8:3-9 (emphasis added). Further, Appellants explain that Using MIMO, in a scenario such as that shown in Figure 1 or 6, each MS 110 receiving any data with a given channelisation [sic] code must, in general, have sufficient antennas 118 or other means to separate each of the different data sub-streams, perhaps discarding any unwanted ones. In known MIMO systems this requires at least M antennas, where M is the number of independent data sub-streams being transmitted with that channelisation [sic] code. Id. at 10:7-12 (emphases added); see also App. Br. 4 (citing Spec. 10:18-21 (“It is also important that the number of antennas, or ability to process multiple data streams, at each MS 110 is known to the BS 100.” (emphasis added))). Thus, the Examiner concludes that signalling the number of antennas at the secondary station, e.g., a mobile user, teaches “signaling . . . the number of simultaneous data streams that the secondary station is capable of receiving.” Advisory Action 2; Ans. 11. We agree. Appeal 2010-009034 Application 10/128,636 7 Appellants argue that Wallace 146 discloses a method for “negotiating” a transmission scenario between the base station and a mobile user. App. Br. 8; see also Reply Br. 6. In particular, Appellants argue that, in Wallace 146, the base station “queries” the mobile user for the mobile user’s antenna diversity status. App. Br. 8. Because Wallace 146 discloses “querying” the mobile user to “extract” antenna diversity (see Wallace 146, ¶ [0125]), Appellants argue that their claim language is different from the disclosure of Wallace 146 and that Wallace 146 does not disclose “signaling,” as recited in claim 1. App. Br. 9. We disagree. Wallace 146 clearly teaches that the mobile user may inform the base station of the number of receive antennas. Wallace 146, ¶ [0125]. The Examiner acknowledges that Wallace 146 teaches “querying” the mobile user to “extract” the antenna diversity status information. Advisory Action 2. Nevertheless, we do not construe Appellants’ claim 1 as proscribing such querying. In particular, we note that the preamble to claim 1 includes the transitional term “comprising.” App. Br. 15. “‘Comprising’ is a term of art used in claim language which means that the named elements are essential, but other elements may be added and still form a construct within the scope of the claim.” Genentech, Inc. v. Chiron Corp., 112 F.3d 495, 501 (Fed. Cir. 1997). Thus, the language of claim 1 is broad enough to encompass the type of querying disclosed in Wallace 146. Appellants further argue that “the number of simultaneous data streams that a station can receive or process, as recited in claim 1, is not dependent upon the number of receive antennas.” App. Br. 9. In particular, Appellants argue that other software or hardware may be adapted to process diversity signals over fewer than all of the receive antennas and that “the Appeal 2010-009034 Application 10/128,636 8 number of receive antennas does not necessarily indicate that all the receive antennas are available for receiving data streams.” Id. (emphasis added); Reply Br. 4-5. It is well settled that “[d]uring patent examination the pending claims must be interpreted as broadly as their terms reasonably allow.” In re Zletz, 893 F.2d 319, 321 (Fed. Cir. 1989). Thus, in construing a limitation, we apply the broadest reasonable meaning of the words in their ordinary usage, as those words would be understood by one of ordinary skill in the art, taking into account any definitions supplied by Appellants’ Specification. In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). Referring to the portions of the Specification quoted above, we find that the number of receive antennas is one measure of the number of simultaneous data streams that a secondary station is capable of receiving. See Spec. 8:3- 9; 10:7-12. Moreover, we construe the language of claim 1 broadly enough to encompass this measure. If Appellants intended to proscribe this measure, they did not so limit the language of claim 1. “It is the [Appellants’] burden to precisely define the invention, not the [U.S. Patent and Trademark Office’s].” Morris, 127 F.3d at 1056. In addition, to the extent that the number of antennas alone is not sufficient to describe the secondary stations capability to receive simultaneous data streams, the Examiner finds that Wallace 146 describes providing “reception diversity information, as well as other parameters of the mobile user,” which sufficiently discloses other hardware and software adaptations. Ans. 10-11 (quoting Wallace 146, ¶ [0125]). Therefore, we are not persuaded that Wallace 146 does not disclose the disputed limitation of claim 1. Appeal 2010-009034 Application 10/128,636 9 Finally, the Examiner concludes that “[a]ccounting for both the state of the communication channels as well as the capabilities of the stations would enable optimal configuration of the communication system.” Ans. 5; Final Rej. 4. In response, Appellants argue that the Examiner fails to provide a reason for combining Wallace, Kogiantis, and Wallace 146 to achieve Appellants’ invention, as recited in claim 1, or that the Wallace 146 teaches away from Appellants’ claimed invention. In particular, Appellants argue that a “universal” goal of wireless transmission is to minimize and reduce the amount of information transmitted and that the addition of extraneous information, such as “querying” information, to the signal transmission in Wallace 146 is contrary to this goal. App. Br. 10; Reply Br. 6. The Examiner contends that this additional information is transmitted in response to the query from the mobile user to the base station and that this information may improve wireless communication efficiency in other ways. Ans. 11-12. Regardless whether this is correct, it is not relevant to the claim at issue in this rejection. The general goals described by Appellants are not recited in claim 1, and, thus, Appellants’ arguments are not commensurate with the scope of the claim language. See In re Tiffin, 448 F.2d 291 (CCPA 1971) (per curiam) (Objective evidence of non-obviousness must be commensurate with the scope of the claims.). Therefore, we are not persuaded by these arguments that the Examiner’s reason to combine the teachings of these references lacks some rational underpinning to justify the obviousness conclusion. For the foregoing reasons, Appellants have not persuaded us of error in the rejection of: independent claim 1; independent claims 2, 9, and 14, with respect to which Appellants raise substantially the same arguments Appeal 2010-009034 Application 10/128,636 10 raised with respect to claim 1; and dependent claims 3-7 and 11-13, which are not argued separately with particularity. Therefore, we sustain the rejection of claim 1-7, 9, and 11-14. OBVIOUSNESS REJECTION OVER WALLACE, KOGIANTIS, WALLACE 146, AND TIEDEMANN As noted above, the Examiner finds that Wallace, Kogiantis, and Wallace 146 disclose all of the limitations of independent claims 1 and 2, from which claims 8 and 10 depend, respectively. Ans. 3-6. Nevertheless, the Examiner acknowledges that these references do not disclose the limitations added by dependent claims 8 and 10. Id. at 8-9. The Examiner finds, however, that Tiedemann discloses the additional limitations of claims 8 and 10. Id. Although Appellants’ arguments regarding independent claim 1 are relatively well-developed, Appellants’ arguments for these dependent claims are not. Initially, Appellants adopted the unpersuasive arguments from independent claim 1. With respect to the additional elements of the dependent claims, Appellants simply state that the additional limitations are not present in Tiedemann and assert non-obviousness over the combined teachings of the prior art. App. Br. 13. We interpret “Rule 41.37 to require more substantive arguments in an appeal brief than a mere recitation of the claim elements and a naked assertion that the corresponding elements were not found in the prior art.” In re Lovin, 652 F.3d 1349, 1357 (Fed. Cir. 2011). Nevertheless, in view of Tiedemann’s disclosure (Final Rej. 7-8 (citing Tiedemann, ¶ [0040]; Figs. 5A-B)) and to the extent that Appellants present arguments alleging deficiencies in Tiedemann’s disclosure with respect to claims 8 and 10, we are not persuaded by Appellants’ arguments. Appeal 2010-009034 Application 10/128,636 11 Therefore, for the foregoing reasons, we sustain the rejection of claims 8 and 10. CONCLUSION The Examiner did not err in rejecting claims 1-14 under § 103(a). DECISION The Examiner’s decision rejecting claims 1-14 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)(iv). AFFIRMED babc Copy with citationCopy as parenthetical citation
