    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableNot shown unpatentable

      “We agree with Patent Owner that Petitioner’s contentions in this ground do not cure the issues for limitations 1D and 1E. Petitioner’s contentions in this ground involve combining Khan and Ali’s teachings of identifying a horizon line and lane lines with Choe. For example, Petitioner argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have combined known elements according to known methods to yield predictable results” and that “[i]mplementing these known mathematical models in Choe’s calibration system, according to their known functions, would have yielded predictable results.” Pet. 39. Petitioner further argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have used a known technique (predictive models) to improve similar devices in the same way” and that “[u]sing predictive models for Choe’s lane and horizon prediction would have also applied a known technique (predictive models) to a known device (a manual annotator device) ready for improvement.” Pet. 40. Petitioner’s proposed combination, therefore, still relies on Choe’s teachings of transmitting an overlaid image to an annotator device. We note that Petitioner asserts that, “[o]nce Khan in view of Ali identifies the horizon and lane lines, it overlays the horizon line and/or lane lines on the video, as shown in the screenshots below.” Pet. 41–42. Although Petitioner mentions Khan and Ali’s teachings with respect to video here, Petitioner does not adequately explain how the teaching of an overlaid video would be combined with Choe’s single image annotator teachings. As discussed above, Choe discloses transmitting a single overlaid image to the annotator” slip op. at 23

      “Thus, Petitioner has not provided sufficient evidence and argument to explain how the additional teachings of Khan and Ali teach limitations 1D and 1E in combination with Choe. Petitioner, therefore, has not demonstrated unpatentability of claims 1–5 by a preponderance of the evidence. F. Obviousness over Choe and Workman (Claims 1–4) Petitioner asserts that claims 1–4 would have been obvious over the combined teachings of Choe and Workman. Pet. 47–52; Pet. Reply 26–30. Petitioner asserts that, “if [Patent Owner] alleges that Choe does not explicitly disclose which predictive models it uses or whether it uses predictive models to identify the horizon line, a [person of ordinary skill in the art] would have searched for references that use predictive models and how such models were used,” which “would have led to Workman, which discloses predictive models to identify the horizon line.” Pet. 47. According to Petitioner, “[u]sing Workman’s predictive model to identify the horizon line would also have merely been combining known elements ([convolutional neural networks (CNNs)] and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way.” Pet. 48–49. Thus, Petitioner relies on Workman to teach a predictive model to identify a horizon line. See Pet. 47–49. Choe with respect to limitations 1D and 1E. Indeed, Workman involves horizon line estimation in single images. See Ex. 1011, 10 (§ 5) (“We introduced Horizon Lines in the Wild (HLW), a new dataset for single image horizon line estimation, to address the limitations of existing horizon line detection datasets.”). Petitioner, therefore, has not demonstrated unpatentability of claims 1–4 by a preponderance of the evidence.” slip op. at 24

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Patent Owner does not provide a different assessment of the level of ordinary skill, but Dr. Przybylski states that an individual with the level of experience identified by Petitioner “would have less knowledge and familiarity” than presumed by Petitioner’s definition. Ex. 2003 ¶ 46. Dr. Przybylski, however, provides no further discussion explaining this apparent disagreement with Petitioner, nor does he set forth what level of knowledge and familiarity a person of ordinary skill in the art would have had. Based on the complete trial record, we determine that Petitioner’s proposed skill level is consistent with the level of ordinary skill evidenced by the ’314 patent and the asserted prior art, and we adopt that skill level with the exception of the phrases “at least,” which introduce vagueness as to the amount of experience.” slip op. at 6

      “We disagree with Petitioner’s interpretation. Taking Petitioner’s point that “‘specified data rate’ means only that the data rate is specified in some way” (Pet. Reply 4), we do not see how, once the rate is specified, claim 1’s later recitations of “the specified data rate” could refer to any other rate, as Petitioner’s arguments suggest. Petitioner argues that “it is clear that the ‘specified data rate’ that provides antecedent basis for later recitations of that term is merely the data rate specified for ‘communicat[ing] data’ between the ‘memory module’ and the external ‘memory controller of the computer (alteration by Petitioner). We agree with this statement, and later recitations of “the specified data rate,” therefore, refer to the data rate that is so specified. Petitioner provides no persuasive argument to support its position that later recitations of “the specified data rate” could be satisfied by data rates that are not the “specified data rate.”” slip op. at 7

      “PO Resp. 19; see also Ex. 2003 ¶¶ 68–72 (Dr. Przybylski’s testimony explaining this annotated figure). Halbert’s Figure 5 is a timing diagram for two consecutive read operations (Ex. 1005 ¶¶ 16, 37), and Patent Owner includes annotations to show each of ranks 140 and 142 outputting data onto their respective data busses at half the rate that data are output from data interface circuit 120 on the DQ data line. In particular, Halbert explains that each of ranks 140 and 142 is “capable of performing m-bit-wide data transfers.” Ex. 1005 ¶ 30. On a read command, rank 140 sends m-bit-wide data to bi-directional data register 126 on line RDQ0 at the same time that rank 142 sends m-bit-wide data to bi-directional data register 128 on line RDQ1, as shown in Figure 5 between T7n and T8n. Ex. 1005 ¶¶ 31–32, 39. Halbert discloses that register 126 or from register 128 to output to buffer 122, which are then output on line DQ. Ex. 1005 ¶ 33. Halbert explains that “[d]ata is serialized from the data registers onto the memory data bus by reading 2m bits into the data registers during one memory device read cycle, and then driving these bits, m at a time, through MUX 124.” Ex. 1005 ¶ 33. As shown in Halbert’s Figure 5, over one clock cycle (T7n–T8n), each of ranks 140 and 142 outputs one piece of m-bit-wide data, and over one clock cycle (T8–T9), those two pieces of m-bit-wide data are output on line DQ to the system memory data bus. Halbert explains that the second read operation proceeds in the same fashion as the first and that “[t]he net result is that the memory data bus transfers 4m bits of data in two memory bus clock cycles (four mbit transfers), with only two data accesses performed at each memory device on the module.” Ex. 1005 ¶ 42. Thus, Halbert’s memory module outputs data to the system memory data bus at twice the rate that each of ranks 140 and 142 outputs data. See Ex. 2003 ¶¶ 68–73 (Dr. Przybylski’s credible testimony explaining Halbert’s data rates).” slip op. at 11

      “1. media player Patent Owner contends that, based on the “intrinsic record . . . an ordinary artisan would have understood the ordinary and customary meaning of ‘media player’ in the ’289 patent refers to application software and does not encompass hardware devices.” PO Resp. 14 (citing Ex. 2022 ¶¶ 92–93). Petitioner asserts that it “has not alleged any hardware device is a ‘media player’” and thus, “the Board need not resolve whether ‘hardware devices’ are encompassed by ‘media player.’” Pet. Reply 1. Rather, Petitioner states the media players relied upon in the Petition are all application software. Pet. Reply 1–2. Petitioner specifically states, “Petitioner has identified three ‘media players’ in the prior art. Two of these—Muthukumarasamy’s ‘Video Player[s]’ and Hayward’s ‘media players’ (Petition, 24–27)—are application software. The third ‘media player’ is likewise not a hardware device.” Pet.

      “Muthukumarasamy “controls delivery of selected media content and selects and controls the media devices that deliver the selected media content according to a media type of the selected media content.” Because Muthukumarasamy teaches that the media device displays media content from various disparate sources depending on the media type and media source, a [person of ordinary skill in the art] would have understood the media device loads an appropriate media player depending on the media type and source. Pet. 23–24 (citing Ex. 1008 ¶ 47; Ex. 1005 ¶¶ 66–67). Petitioner, however, proffers insufficient evidence or argument that the content choices described in paragraph 47 of Muthukumarasamy would have led an ordinarily skilled artisan to understand a media player is obtained and loaded in the content presentation device. Rather, Dr. Bederson makes conclusory statements without providing evidence to support the assertions (Ex. 1005 ¶¶ 66–67).” slip op. at 33

      “Muthukumarasamy discussed above. In particular, Petitioner has not explained how Hayward teaches receiving the one or more messages in a system server. Rather, Petitioner relies on Hayward to teach “identify a particular media player for playing content from the file,” and “identify a location of the particular media player.” Pet. 41–45. More specifically, Petitioner contends that a person of ordinary skill in the art “would have been motivated by and found it obvious from Hayward to implement the DBCS (e.g., the RCIBS) to facilitate control of internet content presented at the content presentation device using any number of media players through embedded media player pages, as described in Hayward.” Pet. 65. However, to the extent Petitioner’s assertions rely on “implement[ing] the DBCS (e.g., the RCIBS) to facilitate presentation of internet content at the content presentation device” (Pet. Reply 22), we determine Petitioner has not shown the combined process of Muthukumarasamy and Hayward would include the required messages being received by the server (e.g., zHub/zNode), as opposed to directly by the RCIBS as discussed above. Additionally, Petitioner has not shown, for the zHub/zNode process, that Hayward cures the deficiencies of Muthukumarasamy as set forth above. Accordingly, Petitioner has not shown that the combination of Muthukumarasamy and Hayward teaches “receiving, in a server system, one or more messages from a personal computing device . . . wherein the one or more messages, . . . identify a particular media player for playing content from the file wherein the media player is a computer application operable to present content and control presentation of the content,” as recited in claim 1 and commensurately recited in independent claim 6. Additionally, because claim 2 depends from claim 1 and claims 7 and 8 depend from claim 6, we conclude that Petitioner has not established by a preponderance of evidence that the subject matter of claims 2, 7, and 8 would have been obvious over the combination of Muthukumarasamy and Hayward.” slip op. at 37

Therefore, based on the entire trial record, we determine Petitioner has not established by a preponderance of the evidence that the subject matter of claim 13 would have been obvious over Durand and Bennet under 35 U.S.C. § 103.” slip op. at 19

    • Strike new argumentNew argument disregardedDecided for patent owner

      “In its Reply, as noted by Patent Owner (PO Sur-reply 11), Petitioner offers a new theory, pointing to a different system call of Goyal (Pet. Reply 19–20 (citing Ex. 1090 ¶ 144 (citing Ex. 1002 ¶ 352–354))). Petitioner contends this new argument is to address Patent Owner’s alleged contention that “‘quality of service’ must already be ‘provided’ at the same time when the correspondence to the ‘reference to an object’ is created (Pet. Reply 19 (citing Ex. 1090 ¶ 141)). Thus, in Dr. Negus’ Reply Declaration, Dr. Negus asserts Goyal teaches the recited “quality of service guarantees that correspond to a reference to an object” relying on the “int hsfq_move (int from, int to, .....)” which “is used to move a thread from one leaf node to another”1 (Ex. 1090 ¶ 144). Petitioner’s alleged reliance on the hsfq_move (int from, int to, …….) system call instead of the int hsfq_mknod (char *name, int parent, int weight, int flag, scheduler_id side) system call represents a change in Petitioner’s unpatentability contentions that is presented for the first time in Petitioner’s Reply (see Pet. Reply 19–20). We acknowledge that the Petition mentions a “move” function: “Additionally, system calls are used to remove, move, and administer nodes in the scheduling structure. Goyal also discloses several additional functions to manage the scheduling structure, including removing, moving, and administering nodes.” (Pet. 61 (citing Ex. 1002 ¶¶ 350–352 (citing Ex. 1007 § 4))). But the cited portion of Dr. Negus’ Declaration simply states that there are other system calls, including “int hsfq_parse(char *name, int hint),” “int hsfq_rmnod(int id, int 1 We note Dr. Negus refers to the system call as “int hsfq_move” (see e.g., Ex. 1002 ¶¶ 144, 352) although Goyal discloses the system call as “hsfq_move” (Ex. 1007 § 4). We consider Dr. Negus’ naming to refer to the same system call as disclosed in Goyal. mode),” and “int hsfq_admin(int node, int cmd, void *args)” and the system call “‘int hsfq_move(int from, int to, .....)’ which ‘is used to move a thread from one leaf node to another’” (Ex. 1002 ¶ 352; see also id. ¶ 144 (repeating the same information as paragraph 352)). Additionally, these teachings of Goyal are discussed in conjunction with the limitation “utilizing an application programming interface . . . to establish one or more quality of service guarantees” (id. ¶¶ 356, 359). Thus, Dr. Negus’ initial Declaration does not elaborate on the move function, and the Petition does not rely on the “hsfq_move” system call to teach the limitations of claim 13. Petitioner asserts that this argument in reply is to address “Patent Owner’s new claim construction position” (Pet. Reply 19). We disagree. As outlined above, the Petition does not identify where an object reference is “used in the request,” as specifically recited in claim 13. Petitioner’s new reply argument, therefore, attempts to fill in a gap in Petitioner’s unpatentability contentions from the Petition that was pointed out by Patent Owner. Under the circumstances here, we do not consider this a permissible reply argument (see Patent Trial and Appeal Board Consolidated Trial Practice Guide 73 (Nov. 2019), available at https://www.uspto.gov/sites/ default/files/documents/tpgnov.pdf (“Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.”)). Thus, we do not consider Petitioner’s newly presented contentions.” slip op. at 26

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “ordinary skill in the art as of the time of the ’344 patent (POSITA) would have had a Bachelor’s degree in Electrical Engineering and at least 2 years of experience working in the field of semiconductor logic design.” Ex. 1019 ¶ 13. Neither Patent Owner, nor its declarant, Dr. Przybylski, offers a different assessment of the level of ordinary skill in the art. See Ex. 2003 ¶ 36 (“I am applying the definition of the level of experience of a person of ordinary skill in the art that has been put forward by Dr. Tredennick in his declaration. I do not necessarily agree with the definition offered there, but I do not presently believe that the exact level of experience of a person of ordinary skill impacts my opinions offered herein.”). Based on the evidence of record, we adopt Dr. Tredennick’s statement of the level of ordinary skill in the art with the exception of the language “at least.” Thus, we determine that the skill level of a person of ordinary skill in the art would have been that of a person with a bachelor’s degree in electrical engineering and two years of experience working in the field of semiconductor logic design.” slip op. at 6

      “Even if so, the arrangement of the data must be altered to give full effect to the claim language. The portions of the specification of the ’344 patent cited by Petitioner confirm this. In one instance, the ’344 patent states: In the first error coding path 120, the first data arrangement alteration device 122 is adapted to create a second data block on the basis of the first data block, which comprises the given number of data in a second arrangement, and to output it to the first error coder 124. Ex. 1001, 3:63–67 (emphasis added), cited in Paper 47, 2. Another passage states: The data arrangement alteration device 222 is adapted to receive, at the input 222E or 102, a first data block comprising a given number of data in the first arrangement, and to generate, on the basis of the first data block, a second data block comprising the given number of data in a second arrangement . . . . Ex. 1001, 6:14–18 (emphasis added), cited in Paper 47, 2. These passages show that data arrangement alteration takes data and puts those data into a different arrangement. Petitioner also cites the ’344 patent’s disclosure of a deserializer changing the “representation” of data. Paper 47, 2–3 (citing Ex. 1001, 8:58–62, 9:2–7). But, in this operation, “the second data block 440 . . . comprises the same data, namely the 72 bits of the first data block 435 in a second arrangement which is different from the first arrangement of the first data block.” Ex. 1001, 9:32–35 (emphasis added). Petitioner also cites an example in the ’344 patent in which the burst length is halved from eight time pulses to four time pulses. Ex. 1001, 11:52–61, cited in Paper 47, 4. The ’344 patent describes that, in this scenario, only half of the bits (36 out of 72) “will be occupied with processable data.” Ex. 1001, 11:59–60. Petitioner contends that this describes an output of 72 bits that is larger and different than the input of only 36 bits. Paper 47, 4. The ’344 patent, however, describes providing “a further subarea of the matrix 420 for this mode, and to control the multiplexer 430, via the mode register 110, such that this subarea will be read out, so that, for example, only 36 of the 72 bits will be occupied with processable data.” Ex. 1001, 11:56–60 (emphasis added). Thus, it is the subarea having the 36 bits of processable data that is read out. But even if Petitioner is correct that the output is larger than the input in this example, data arrangement alteration still requires an alteration of the arrangement of the input data, even if the output contains additional data. In all of the examples in the specification of the ’344 patent, therefore,” slip op. at 9

      “a data arrangement alteration algorithm’ is described in the ’344 patent as a ‘data arrangement alteration device,’ which is part of the ‘one or more devices’ of the first means of claim 19. Thus, the corresponding structure is ‘a data arrangement alteration device.’” Pet. 10 (citing Ex. 1001, 6:14–25, 6:42–65, 7:10–24; Ex. 1019 ¶ 32). In the Decision on Institution, we addressed Petitioner’s proposed construction for “means for performing a data arrangement alteration algorithm,” but we did not adopt it. Dec. on Inst. 11–12. Rather, we set out the following construction of this term: Limitation Function and Structure Claim 19: means for performing a Function: performing a data data arrangement alteration arrangement alteration algorithm algorithm Structure: data arrangement alteration devices 122, 132, and 222 and equivalents. See id. at 3:27–34, 5:65–6:25, 6:42–65, 8:55–57, 10:34–45, Figs. 1–4. During the trial in this proceeding, neither party further disputed this interpretation. Having considered the entire record developed during trial, we determine that this is the proper interpretation for “means for performing a data arrangement alteration algorithm.” Thus, we apply this interpretation in our analysis below.” slip op. at 13

      “As discussed above in the section addressing claim interpretation, “data arrangement alteration” requires alteration of the arrangement of data, not merely alteration of data. Petitioner’s allegation that Yoon’s data bus inversion alters some portion of the data is insufficient to show that Yoon describes altering the arrangement of data, as required by the claims. For the same reasons, we are not persuaded that Yoon’s data bus inversion devices describe the same or equivalent structure as that set forth in the specification of the ’344 patent, namely data arrangement alteration devices 122, 132, and 222, as set forth in our claim interpretation discussion above. Because Petitioner has not shown Yoon describes the “data arrangement alteration” limitations of independent claims 1, 16, 19, and 43, Petitioner has not proven, by a preponderance of the evidence, that Yoon anticipated these claims. Dependent claims 8–12, 14, 26–31, and 48–51 incorporate the “data arrangement alteration” limitations by virtue of their dependency from their respective independent claims, and, therefore, Petitioner has not proven, by a preponderance of the evidence, that Yoon anticipated these claims.” slip op. at 16
