SMITH, LINDA M. GAUDETTE, and CHRISTOPHER C. KENNEDY, Administrative Patent Judges. GAUDETTE, Administrative Patent Judge. DECISION ON APPEAL 1 1 This Decision includes citations to the following documents: Specification filed June 20, 2014 ("Spec."); Final Office Action dated February 8, 2018 ("Final"); Appeal Brief filed April 4, 2018 ("Appeal Br."); Examiner's Answer dated June 27, 2018 ("Ans."); and Reply Brief filed July 13, 2018 ("Reply Br."). Appeal2018-007439 Application 14/310,548 The Appellant2 appeals under 35 U.S.C. § 134(a) from the Examiner's decision finally rejecting claims 1, 3-16, and 18-30 under 35 U.S.C. § l 12(a) as failing to comply with the written description requirement, and under 35 U.S.C. § 102(a)(l) as anticipated by Conklin (US 6,765,964 Bl, issued July 20, 2004). 3 We REVERSE. The invention relates to compressed sensing, which the inventor describes as "an emerging technology that acquires, compresses and transmits a set of measurements that represent some sort of data signal" (Spec. ,-J 2), such as a video or a picture (id. ,-i 39). According to the Specification, "[ c Jompressed sensing is often used for transmission, where the measurements are generated at one place (the transmitter) sent over a channel and then received by a receiver which reconstructs the original signal." Id. "The measurements are obtained by linear operations on the signal." Id. Measurements transmitted via a communication channel are quantized into codewords and the quantization codewords are transmitted using some form of channel coding. Id. "The communication channel may be a wired or wireless link or it can be a storage medium into which the transmitter writes the measurements, and possibly related data, and from which the receiver reads the measurements, and possibly related data." Id. ,-J 44. "The goal of the quantization and channel coding is to minimize the data rate, i.e. the number of bits required for the transmission of each measurement, while keeping the distortion at a certain level, or equivalently, to minimize the distortion while keeping the data rate at a certain level." Id. 2 The Appellant is the Applicant, Alcatel-Lucent USA Inc. 3 We have jurisdiction under 35 U.S.C. § 6(b). 2 Appeal2018-007439 Application 14/310,548 ,i 39. For example, where measurements are highly dependent, data rate may be reduced by quantizing and transmitting the residual (i.e., the prediction error) instead of the actual measurement. Id. ,i 46. The residual has a much lower energy, and can be encoded at a much lower data rate, than the original predicted measurement. Id. In order to decode measurements, "the decoder needs to 'know' the settings of the encoder, for example, the step size of the quantizer or the linear prediction coefficients." Spec. ,i 4 7. Because the encoder settings are signal-dependent, they cannot be provided to the decoder in advance, but must be transmitted to the receiver as side information. Id. According to the Specification, to achieve a substantial data rate reduction, "the data rate needed for transmitting the side information must be substantially lower than the data rate reduction in the measurements' data rate," thereby precluding direct transmission of the encoder's settings. Id. The Specification thus describes "ways to represent the statistical information that determines the settings of the encoder by a parametric model that is determined by a small number of parameters, which may be estimated from the input signal." Id. ,i 48. According to the Specification, "these few parameters, whose number is fixed and not dependent on the number of measurements, are the only side information that needs to be transmitted in order to enable the receiver to compute the information necessary to decode the measurements." Id. Of the appealed claims, claims 1, 10, 16, and 25 are independent. See generally Appeal Br. 14-21 (Claims Appendix). Claims 1 and 16 are representative, and are reproduced below: 3 Appeal2018-007439 Application 14/310,548 1. A non-transitory machine-readable storage medium encoded with instructions for execution by a source device for compressed sensing of a signal, wherein the source device acquires a set of compressed sensing measurements using a structured sensing matrix, the non-transitory machine-readable medium comprising: instructions for determining a signal specific coding scheme for the set of compressed sensing measurements; instructions for coding the compressed sensing measurements using the determined signal specific coding scheme; instructions for determining a parametric model describing the signal specific coding scheme for the encoded set of compressed sensing measurements; and instructions for transmitting a description of the parametric model via a side communications channel, wherein the side communications channel has a substantially lower data rate than a data rate needed for transmitting the compressed sensing measurements on a main transmission channel. 16. A source device comprising: a memory device; and a processor in communication with the memory device, the processor being configured to acquire a set of compressed sensing measurements of the signal using a structured sensing matrix, determine a signal specific coding scheme for the set of compressed sensing measurements, code the compressed sensing measurements using the determined signal specific coding scheme, determine a parametric model describing the signal specific coding scheme for the encoded set of compressed sensing measurements, and transmit a description of the parametric model via a side communications channel, wherein the side communications channel has a substantially lower data rate than a data rate needed for transmitting the compressed sensing measurements on a main transmission channel. Id. at 14, 18. 4 Appeal2018-007439 Application 14/310,548 The Examiner rejected claims 1, 3-16, and 18-30 under 35 U.S.C. § l 12(a) as failing to comply with the written description requirement, and under 35 U.S.C. § 102(a)(l) as anticipated by Conklin. Independent claims 1 and 10 recite "[a] non-transitory machine-readable storage medium encoded with instructions." The Specification discloses that "[a] machine-readable storage medium may include any mechanism for storing information in a form readable by a machine, such as a personal or laptop computer, a server, or other computing device," and that "a non-transitory machine-readable storage medium may include read-only memory (ROM), random-access memory (RAM), magnetic disk storage media, optical storage media, flash- memory devices, and similar storage media." Spec. ,-J 88. Claim 1 recites that the instructions are for execution by "a source device" and claim 10 recites that the instructions are for execution by "a destination device." Independent claim 16 recites "[a] source device" and independent claim 25 recites "[a] destination device." A source device and a l 12 Input Signal 114 S1911al Actiuisilkm System Structured Sensing Matrix Geiieralot 110 Recorstmcted Compressed Measurement Gerwrator 116 136 Input Signal Compressed ------ Mtas·urement Decoder Channel Encoder 118 130 138 Cminnm Deoocter FIG. 1 5 Side Channer Parametric Model Information Side Channet Parametric Model Information Appeal2018-007439 Application 14/310,548 destination device are described in connection with Figure 1, reproduced below: Figure 1 "illustrates a communication system using compressed measurements to transmit a signal." Spec. ,i 67. Communication system 100 includes at least one source device 110 for acquiring, encoding and/ or transmitting signal data, and at least one destination device 130 for receiving and decoding the received signal data. Id. "[S]ource device 110 may be any type of device capable of acquiring signal data and encoding the signal data . . . . [S]ource device 110 may include at least one processor and a memory for storing instructions to be carried out by the processor." Id. ,i 68. "[D]estination device 130 may be any type of device capable of receiving, decoding and displaying signal data that may receive signal data from the network 120. The receiving and decoding or any other function of the destination device 130 may be controlled by at least one processor." Id. ,i 69. Communication system 100 also includes transmission channel 120 that may be any known transmission, wireless or wired channel, or a storage medium to which source device 110 writes data and from which destination device 130 reads data. Id. ,i 67. Claims 1 and 10 recite that the non-transitory machine-readable medium comprises instructions "for transmitting a description of the parametric model" ( claim 1) or "for receiving a parametric model" ( claim 10) "via a side communications channel" ( claims 1, 10). Claims 16 and 25 recite that the source device or destination device, respectively, comprises a memory device and a "processor in communication with the memory device" ( claims 16, 25). Claims 16 and 25 recite that the processor is "configured to" "determine a parametric model ... and transmit a 6 Appeal2018-007439 Application 14/310,548 description of the parametric model" ( claim 16) or "receive a parametric model" ( claim 25) "via a side communications channel" ( claims 16 and 25). Each of independent claims 1, 10, 16, and 25 recites "wherein the side communications channel has a substantially lower data rate than a data rate needed for transmitting the compressed sensing measurements on a main transmission channel" ("the wherein clause"). The Appellant and the Examiner disagree over whether the written description supports the wherein clause and whether Conklin discloses the features recited in the wherein clause. The Examiner found the written description does not support the wherein clause in claims 1, 10, 16, and 25 because "[t]here is no teaching of a 'main transmission channel' that is separate from a 'side communications channel."' Final 3. The Examiner found "[t]he [S]pecification appears to simply teach 'side information' which is transmitted via 'the communications channel' 120." Id. The Examiner found Conklin's transmission media 9 meets the limitation recited in the wherein clause (see Final 4, 6, 8, 9). In the Answer, the Examiner explains that this finding is based on an interpretation of the claims as requiring only "a single transmission channel having a required data rate that is lower than a hypothetical transmission channel that would be required to transmit the compressed sensing measurements." Ans. 3. The Examiner contends the claims do not recite that the compressed sensing measurements are transmitted, and "there is no required side communications channel, only a primary transmission channel which has a lower required data rate than a transmission channel that would be used to transmit the compressed sensing measurements." Id. at 3-4. 7 Appeal2018-007439 Application 14/310,548 The Appellant contends Specification paragraphs 47, 75, and 76 provide support for a side channel that differs from the channel that is used for direct transmission (transmission channel 120). Appeal Br. 7. The Appellant argues "Conklin cannot anticipate the claimed subject matter because Conklin only discloses transmission through medium 9, a single channel with only one data rate." Id. at 9 (emphasis omitted). For the reasons discussed below, the Appellant's arguments are persuasive of reversible error in the Examiner's rejections of claims 1, 3-16, and 18-30 under 35 U.S.C. § l 12(a) and under 35 U.S.C. § 102(a)(l). Turning first to the rejection under 35 U.S.C. § l 12(a), the Examiner attempts to support a finding that the Specification fails to teach a main transmission channel that is separate from a side communications channel by relying on Figure 1. See Ans. 2. The Examiner argues Figure 1 "illustrates diagonal lines with arrows pointing to a transmission channel 120[, but] [t]here is no indication of a side communication channel in the drawings." Id. ( emphasis omitted). "[D]rawings in a patent need not illustrate the full scope of the invention." See Arlington Indus., Inc. v. Bridgeport Fittings, Inc., 632 F.3d 1246, 1254 (Fed. Cir. 2011) (citing MBO Labs., Inc. v. Becton, Dickinson & Co., 474 F.3d 1323, 1333 (Fed. Cir. 2007) ("[P]atent coverage is not necessarily limited to inventions that look like the ones in the figures. To hold otherwise would be to import limitations onto the claim from the specification, which is fraught with danger.")). With reference to Figure 1, the Specification discloses that destination device 130 receives encoded compressed sensing measurements from source device 110 via transmission 8 Appeal2018-007439 Application 14/310,548 channel 120, and that source device 110 generates a parametric model that is transmitted to destination device 130 as side information. See Spec. ,i,i 85, 86. The Specification discloses, more specifically, that channel decoder 138 in destination device 110 "receive[s] a parametric model and parametric data via a side channel from the channel encoder 118" that is used to decode the encoded compressed sensing measurements. Id. ,i 75. The Examiner has not explained persuasively why the ordinary artisan would not have understood the disclosure in paragraphs 75, 85, and 86 as describing two separate channels. Nor has the Examiner explained why the ordinary artisan would not have understood Specification paragraph 4 7, quoted on page 3, above, as disclosing that "the side communications channel has a substantially lower data rate than a data rate needed for transmitting the compressed sensing measurements on a main transmission channel" ( claims 1, 10, 16, 25). Accordingly, because the Appellant has argued persuasively that the Examiner has not met the burden to show that the claims lack written descriptive support, we do not sustain the rejection of claims 1, 3-16, and 18-30 under 35 U.S.C. § l 12(a). Turning next to the rejection under 35 U.S.C. § 102(a)(l), the Examiner contends the wherein clause reads on Conklin' s transmission media 9 because the claims require only "a single transmission channel having a required data rate that is lower than a hypothetical transmission channel that would be required to transmit the compressed sensing measurements." Ans. 3. The Examiner contends the claims do not recite that the compressed sensing measurements are transmitted, and "there is no required side communications channel, only a primary transmission channel 9 Appeal2018-007439 Application 14/310,548 which has a lower required data rate than a transmission channel that would be used to transmit the compressed sensing measurements." Id. at 3-4. The Examiner's claim interpretation is incorrect for at least the following two reasons. First, none of the claims positively recite either a side communications channel or a main transmission channel as an element of the claims. Second, the Examiner fails to appreciate that although "there is no required side communications channel" in the claims (Ans. 3-4), claims 1 and 10 require a non-transitory machine-readable storage medium comprising instructions for transmitting or receiving a parametric model "via a side communications channel ... ha[ ving] a substantially lower data rate than a data rate needed for transmitting the compressed sensing measurements on a main transmission channel," and claims 16 and 25 require a source device or a destination device comprising a processor configured to transmit or receive a parametric model "via a side communications channel ... ha[ ving] a substantially lower data rate than a data rate needed for transmitting the compressed sensing measurements on a main transmission channel." The Examiner has not identified with sufficient specificity a description in Conklin of a non-transitory machine-readable storage medium comprising instructions as recited in claims 1 and 10, or of a processor configured in the manner recited in claims 16 and 25. See Final 4, 6, 8, 9. Because the Examiner has not identified in Conklin a teaching of each and every claim limitation recited in independent claims 1, 10, 16, and 25 we do not sustain the rejection of claims 1, 3-16, and 18-30 under 35 U.S.C. § 102(a)(l).
