“We are persuaded by Patent Owner’s argument that claim 1 is not obvious over Avellan because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 21–23. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. PO Sur-reply 20. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

Neither party presents any arguments relating or referring to the level of ordinary skill in the art. Determining the level of ordinary skill in the art involves various factors, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

“3. Motivation to Combine Buibas and Sinyavskiy Petitioner argues that “it would have been obvious to partition Buibas’[s] spiking networks according to the specific techniques disclosed in Sinyavskiy” for multiple reasons. Pet. 13 (citing Ex. 1005 ¶¶ 71–72, 85, 92, 179–203; Ex. 1006 ¶¶ 12, 185, 188, 191, Fig. 6A; Ex. 1003 ¶ 63). First, Petitioner asserts, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to parallelize task execution on the robot and improve learning capabilities (e.g., through faster learning, greater computing efficiency, and task-specific learning models) of the Buibas mobile robotic apparatus as described by Sinyavskiy and discussed by Dr. Janet.” Id. (citing Ex. 1003 ¶ 64). Second, Petitioner contends, “partitioning Buibas’[s] robotic brain as suggested by Sinyavskiy would have beneficially expanded the range of tasks that the robot could perform by dedicating partitions to specialized tasks.” Id. at 13– 14 (citing Ex. 1006 ¶¶ 12, 185, 188, Fig. 6A; Ex. 1005 ¶¶ 71–72, 85, 92, 179–205; Ex. 1003 ¶ 65). Third, Petitioner argues, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to permit unused partitions or unused resources in the partitions to be reassigned for different tasks,” which would allow for a network processing apparatus that has increased processing capability for the same network capacity while also having a lower cost, size and power consumption. Id. at 14 (citing Ex. 1006 ¶¶ 190–192, 105, 34, code (57); Ex. 1003 ¶ 66). Fourth, Petitioner argues that “Buibas briefly mentions that its spiking neural networks can be partitioned but discloses little detail about the partitioning,” which would invite one of ordinary skill to turn to other references, such as Sinyavskiy, for additional detail on how to implement partitioning. Pet. 14–15 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 67). Fifth, Petitioner asserts, combining Buibas and Sinyavskiy would merely “involve[] the application of known techniques (e.g., Sinyavskiy’s partitioned neural network) to a known system (e.g., Buibas’[s] mobile robot and robotic brain) to yield predictable results (e.g., Buibas’[s] robot using a spiking neural network partitioned as taught in Sinyavskiy),” particularly because “the partitioning of the Buibas neural network is reminiscent of Recurrent Fuzzy Neural Networks (RFNNs) that were already commonplace at the end of the 1990’s.” Id. at 15 (citing Ex. 1003 ¶ 68). Finally, Petitioner contends, the proposed combination merely involves “use of known techniques (e.g., Sinyavskiy’s partitioned neural network) to improve a similar system (e.g., Buibas’[s] mobile robot and robotic brain).” Id. (citing Ex. 1003 ¶ 69). Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70).” slip op. at 14

“We agree with Patent Owner and Dr. Saber that these “weights” are numerical values associated with connections among neurons, and the “weight vectors” are merely lists of weights. PO Resp. 13–14; Ex. 2001 ¶¶ 66–67. When input is provided to the neural network, the network uses the weights of its connections in a feedforward calculation manner to provide an output that can include an instruction for operating a device. Ex. 2001 ¶ 66. We agree with and find credible Dr. Saber’s testimony that Buibas’s merging of weights or weight vectors results in updated network weights, and does not, by itself, disclose the merging of instruction sets for operating a device, or the correlation of the same set of inputs for all or a portion of a circumstance representation with instruction sets for operating two different devices.

“Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” is too narrow. Although Patent Owner points to various parts of the ’518 patent as supporting its restrictive proposal, other parts of the patent are not so limited. For example, the patent’s technical field and summary are not limited to coaxial cable, and the patent discusses twisted pair wiring and satellite communications as media that can be used. See, e.g., Ex. 1001, 1:27–29, 3:33–35, 3:49–50, 3:67–4:3, 5:61–6:3, 8:20–23, 9:28–33. Accordingly, we adopt the following level of ordinary skill in the art for use in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to four years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find that this skill level is consistent with the problems and solutions identified in the ’518 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citing Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed.

“We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed. Cir. 2022) (construction of term in independent claims should not render dependent claims superfluous or lacking scope).” slip op. at 20
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownDecided for petitioner
“We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra. Having decided proper constructions for the disputed terms, we proceed in our analysis to consider the parties’ arguments concerning the challenge grounds. In the following sections, we apply the plain meaning of the claim terms, and as necessary, specify what the plain meanings are.” slip op. at 23

“C. Level of Ordinary Skill in the Art Petitioner contends as follows: A POSITA8 would have had a bachelor’s degree in electrical engineering, computer engineering, or a similar discipline, and three to four years of experience working in signal processing and/or communication systems/networks. Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art. We adopt and apply Petitioner’s proposed skill level because it is consistent with the problems and solutions identified in the ’690 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.
