      “arguments and evidence in support of its proposed definition of the level of ordinary skill in the art at the time of the invention, we determine that Petitioner’s definition is too broad. Petitioner asserts that one of ordinary skill in the art would have “approximately one or more years of professional experience with electronic and optoelectronic system design.” Pet. 3. But Petitioner does not appear to dispute the testimony of Patent Owner’s declarant, Dr. Bretschneider, that “the field of optoelectronics” is “broad and expansive and encompasses solar cells, optical fiber, and any application of LEDs, not just the design of LED packages.” Ex. 2020 ¶ 78. Therefore, one having experience with optoelectronic system design would not necessarily have experience designing LED backlights for LCD displays. We have also carefully considered Patent Owner’s arguments and evidence in support of its proposed definition of the level of ordinary skill in the art at the time of the invention. In light of our analysis of the prior art and the AAPA, we determine that Patent Owner’s requirement of “at least one year of practical experience in design of LED packages and one year of practical experience in design of thermal management systems for LEDs” is not sufficiently precise. Patent Owner does not specify that the required experience is in the context of designing LED backlights for LCD displays. One having this experience would necessarily have experience addressing thermal-management concerns associated with such backlights.” slip op. at 18

We agree with Petitioner that “connecting” should be construed consistently with the “fastener” term, because it is the “fastener” (or the second portion thereof) to which the circuit board is “connecting.” Because the parties agree that “fastener” is “[a] feature that attaches or holds something in place, “connecting” means “attaching or holding.”” slip op. at 26

      “prosecution history and the amendment changing “held at” to “accessible at,” testimony upon which Patent Owner relies to support its position. Specifically, Dr. Medvidović testifies that a person having ordinary skill in the art would have understood the two phrases to be synonymous because, 1) the amendment was not made to overcome a prior art reference, 2) the applicant did not make a statement disclaiming that “being accessible at” does not encompass “being held at,” and 3) the examiner did not object to the amendment as exceeding the scope of the Specification. See Ex. 2005 ¶ 34. We find that Dr. Medvidović’s conclusion is not supported by his reasoning. First, an amendment made not to overcome a prior art reference does not mean an amendment that does not change the scope of a claim. An applicant is free to amend a claim at any time during prosecution, even an amendment that may expand the scope of a claim (one made not to overcome a prior art rejection). Second, whether “being accessible at” encompasses “being held at” is not the issue—because the scope of one term encompasses the scope of another term does not make the two terms” slip op. at 26

      “We decline to adopt Patent Owner’s implicit construction that would require “selecting an entity pair from” all of the entity pairs of “said plurality of transport entities.” Contrary to Patent Owner’s arguments addressing the claim language, the plain language of claim 1 does not require the selection to be from all of the entity pairs of the plurality of transport entities for which an overall cost has been determined. The plain language of claim 1 also does not preclude the selection to be from a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined. Rather, dependent claim 9, through its dependence on claims 1 and 4, explicitly allows for the selection to be from a subset of the entity pairs of the plurality of transport entities. Patent Owner’s arguments advocate for the importation of limitations from the ’821 Patent Specification into the claim––namely the disclosure that all entity pairs of transport entities examined in step 220 of Figure 2 are input to the entity pair selection step 230. See PO Sur-reply 4. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.2d 1182, 1186 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). An extraneous limitation is “a limitation read into a claim from the specification wholly apart from any need to interpret what the patentee meant by particular words or phrases in the claim.” E.I. du Pont de Nemours, 849 F.2d at 1433. Accordingly, we construe “selecting an entity pair from said plurality of transport entities based at least upon said overall cost” according to its plain meaning, the scope of which includes selecting an entity pair from all or a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined.” slip op. at 11

      “Considering the evidence of record on both sides, we find Petitioner’s argument persuasive that Baker teaches a “mapping” as recited in limitation 1.4. Baker’s disclosure of a “mapping” is explicit. See, e.g., Ex. 1005 ¶ 69, 83. And the evidence shows that this mapping occurs “in advance of a communication,” and may, for example, take place in the head node as part of the Administer Ring routine. See, e.g., Ex. 1005 ¶¶ 51–56, 76. That intermediate rings are ultimately configured to simply forward traffic “according to preconfigured rules” (Ex. 1005 ¶ 87) rather than to perform more complicated routing has no pertinent bearing on the process corresponding to the recited “mapping” step, which occurs “in advance” of the communication and any such forwarding (id. ¶ 76).” slip op. at 26

      “allocating bandwidth as part of its resources and that, in light of Wright, a person of ordinary skill in the art would have had reason to make this allocation for each of the links in of the physical topology (see Ex. 1006 ¶ 18 (“bandwidth allocation at each link”)) using information from both (1) the bandwidth requirements of Baker’s logical connections and (2) the mapping between Baker’s logical and physical topologies. As Petitioner persuasively argues, we find that Wright’s teaching of further details on ensuring the availability of bandwidth, in a similar context, would have been sufficient motivation for a person of ordinary skill in the art to incorporate Wright’s teachings into Baker’s method. We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology. See Pet. 36; Pet. Reply 22–23; Ex. 1007 ¶ 17; Ex. 1003 ¶¶ 94–96; Ex. 1036 ¶¶ 49–51. We also disagree with Patent Owner that Petitioner has failed to adequately explain how a person of ordinary skill in the art would have modified Baker’s method to apply Wright’s teachings on bandwidth allocation, such as how Baker’s head node N0 would have been modified. See PO Resp. 31–32. Based on the level of ordinary skill and the level of detail in Baker, Wright, and the ’431 patent, and crediting Dr. Houh’s testimony, we find Petitioner’s argument persuasive that such modification would have been within the capability of someone of ordinary skill in the art. See Pet. 17–20 (citing Ex. 1003 ¶¶ 42–46, 48). And we agree with Petitioner that modifying Baker with Wright’s teachings would have been “nothing more than the combination of known elements . . . according to known methods . . . to yield predictable results.” Pet. 20 (citing Ex. 1003 ¶ 47).” slip op. at 32

      “For reasons explained in the Petition and Petitioner’s Reply, we agree with Petitioner that the Baker–Wright–Holender ’699 combination teaches summing the two bandwidths determined in “allocating” steps 12.5 and 12.7 to determine a total allocation for each of the physical links—motivated by the known need to ensure that bandwidths do not exceed the available physical link capacity. We disagree with Patent Owner that Holender ’699’s discussion of summing is merely describing a physical constraint. Holender ’699 teaches normalizing the logical link capacities, which requires summing the logical link capacities. See Ex. 1007, 8:38–51. We credit Dr. Houh’s testimony that this “confirms that [Holender ’699’s] teachings about summing are not simply ‘explaining a physical constraint,’ but actually performed.” Ex. 1036 ¶ 61. Holender ’699 refers to capacities 𝐶𝐶𝑗𝑗 as “logical link capacities for each logical link j over all logical networks. Ex. 1007, 6:52–55. But when mapped to physical links, Holender ’699 denotes capacities 𝐶𝐶𝑘𝑘𝑘𝑘 as “capacities of the logical links [𝑙𝑙] that need capacity on the k:th physical link.” Ex. 1007, 8:38–43. In other words, they are the capacities, or bandwidths, allocated to each physical link 𝑘𝑘 for implementing associated logical link 𝑙𝑙. See also id. at 6:60–67 (describing a matrix designed to indicate “if logical link j needs capacity on the k:th physical link.”).” slip op. at 50

      “Relying on Dr. Houh’s testimony, Petitioner argues that a person of ordinary skill in the art “would have had a working knowledge of the networking art that is pertinent to the ’431 patent, including network communications techniques and bandwidth management methodologies,” and “would have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent, and two years of professional experience relating to network communications including the use of logical topologies and bandwidth management. Lack of professional experience can be remedied by additional education, and vice versa.” Pet. 3 (citing Ex. 1003 ¶¶ 18–20). Patent Owner adopts Petitioner’s proposed definition of the level of ordinary skill. PO Resp. 3. Because Petitioner’s articulation of that level of skill is uncontested, supported by testimonial evidence, and appears consistent with the types of problems and solutions in the ’431 patent, we adopt it for this decision. See, e.g., Ex. 1001, 1:5–6:14.” slip op. at 8

But if a construction is necessary, Petitioner argues that the we should construe in response to as “using,” consistent with how the claimed invention is described in the ’431 patent. Id. at 10–11 (citing Ex. 1001, 2:52–6:10, 8:52–9:2; Ex. 1036 ¶¶ 7–11). Petitioner disagrees that the term means “based on” because limitation 1.3 uses the phrase based on, suggesting that the applicant made a conscious decision to use different language in limitation 1.5. Id. at 11 (citing Ex. 1036 ¶ 11). Patent Owner responds that its two proposed constructions are synonymous, and argues that Petitioner agrees that in response to encompasses “using” or “using information from.” PO Sur-reply 8 (citing Ex. 1001, 2:22–26). Patent Owner contends that its proposed construction resolves a controversy because in Patent Owner’s view, the Baker–Wright combination does not use information from the recited mapping to allocate bandwidth. Id. at 9–12 (citing Ex. 1006 ¶¶ 5, 17, 24; Ex. 2009, 52–56; Ex. 2008 ¶¶ 62–76). Similarly, Patent Owner contends that Holender ’699 does not teach mapping. Id. at 12–13 (citing Ex. 1007, 3:15–17; Ex. 2008 ¶¶ 89–92). We see no significant difference between Petitioner’s proposed construction of in response to as “using” and Patent Owner’s proposed construction as “using information from.” Thus, it does not appear that the construction of in response to is in controversy. Thus, we need not construe the term for this decision. Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “We find Petitioner’s arguments persuasive that Baker teaches allocating bandwidth as part of its resources and that, in light of Wright and Holender ’699, a person of ordinary skill in the art would have had reason to make this allocation for each of the links in of the physical topology (see Ex. 1006 ¶ 18 (“bandwidth allocation at each link”)) using information from both (1) the bandwidth requirements of Baker’s logical connections and (2) the mapping between Baker’s logical and physical topologies. As Petitioner persuasively argues, we find that Wright’s teaching of further details on ensuring the availability of bandwidth, in a similar context, would have been sufficient motivation for a person of ordinary skill in the art to incorporate Wright’s teachings into Baker’s method. Holender ’669 provides further supporting disclosure. We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology.

      “The ’291 patent addresses a problem with a cellular telephone or mobile device and the objects of the ’291 patent are related to the cellular telephone or mobile device. See, e.g., Ex. 1001, 1:22–55, 2:53–58. Thus, “what the inventors actually invented and intended to encompass by the claim” was related to a cellular telephone or mobile device. The ’291 patent indicates that the “portable handheld mobile device with a plurality of antennas” of the preamble of claim 5 should be treated as a limitation. We also agree with Patent Owner that “the preamble is limiting because several limitations in claim 5’s body ‘rely upon and derive antecedent basis from the preamble,’” specifically “a communication system” and “a plurality of antennas.” PO Resp. 6. The body of claim 5 recites “the system” repeatedly, and “the system” relies upon and derives antecedent basis from the preamble. Ex. 1001, 12:40, 12:44, 12:48, 12:54. The body also recites “the plurality of antennas” that also relies upon and derives antecedent basis from the preamble. Id. at 12:46, 12:50. Because the preamble of claim 5 recites that the “communication system includ[es] one or more communication modules and processors for use in a portable handheld mobile device with a plurality of antennas,” the preamble “recites essential structures for the claimed system,” as argued by Patent Owner.

Petitioner does not address directly Patent Owner’s evidence that shows technical difficulties of implementing a system such as Raleigh’s in a portable handheld mobile device with its practical limitations on size to accommodate an antenna array, power and battery capacity for all the components of Raleigh combined with Sainton, and required heat dissipation for the proposed combination. See generally Pet. Reply. In view of the full record that includes scant argument and evidence supporting Petitioner’s argument that Raleigh’s remote unit 170a would have been “easily modified as a mobile wireless device” and Patent Owner’s extensive argument and evidence to the contrary, Petitioner does not show by a preponderance that one of ordinary skill in the art would have had a reasonable expectation of success in implementing Raleigh’s remote unit as a portable handheld mobile device.
