“Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

“5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

“Dr. Scordilis. Based on the record, Petitioner fails to provide a sufficient reason to arrive at the claimed invention and satisfy the burden of showing obviousness. As Patent Owner essentially argues, Cabot (and all references relied upon by Petitioner and Dr. Scordilis) do not pertain to “quantizing a phase difference of the at least one overtone relative to the fundamental tone to embed at least one bit of the data to be embedded” as step 1C-2 requires. See PO Resp. 32–33. Petitioner also relies on Kudumakis to modify Srinivasan in asserting that step 1C-2 would have been obvious, but Petitioner’s reliance on Kudumakis is also faulty as explained below. See Pet. 22–27 (relying on Ex. 1006 (Cabot), Ex. 1007 (Kudumakis); Ex. 1028 (Risset), Ex. 1031 (Lipshitz), Ex. 1055 (“Cox-SSSW”); Ex. 1020 (“Cox- 1995” ); Ex. 1021 (“Wu”)). articulated reasoning with some rational underpinning” to show that one of ordinary skill in the art would have had a sufficient reason to modify Srinivasan’s frequencies to embed a quantized phase difference between a fundamental and its harmonic into the harmonic as step 1C-2 requires. See Kahn, 441 F.3d at 988 (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)); In re Fine, 837 F.2d 1071, 1075 (Fed. Cir. 1988) (“teachings of references can be combined only if there is some suggestion or incentive to do so”) (quoting ACS Hosp. Sys., Inc. v. Montefiore Hosp., 732 F.2d 1572, 1577 (Fed. Cir. 1984)). As noted above, Dr. Scordilis states that Cabot merely “opens the venue for exploration” for an artisan of ordinary skill to “try to . . . explore” watermarks. Ex. 2011, 75:16–22. Dr. Scordolis’s testimony relates to an “obvious to try” rationale, but neither Dr. Scordilis’s testimony, nor Petitioner’s showing, satisfies the conditions to support that rationale. In particular, Dr. Scordilis does not testify, and Petitioner does not show, that the technique of embedding phase difference codes into a harmonic relative to its fundamental was one of “a finite number of identified, predictable solutions” and a “known option[]” for hiding data. Cf. KSR, 550 U.S. at 402 (indicating that under an “obvious to try” rationale, “[w]hen there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill in the art has good reason to pursue the known options within his or her technical grasp” (emphasis added)).” slip op. at 25

“The record supports Patent Owner’s characterization of Dr Scordilis’s testimony. Dr. Scordilis does not rely on any references that “have a frequencies specifically.” See Ex. 2011, 90:4–8 (testifying such references are “[n]ot in [his] report”). Moreover, Dr. Scordilis testifies that “[t]he value . . . of Cabot’s work is that he points to the fact that even in this very controlled experiment, although phase is detectable in an A/B type of setup under many, many repetitions, it really opens the venue for exploration that a [person of ordinary skill in the art] would try to capitalize and explore further to develop a watermark.” Id. at 75:16–22 (emphasis added). In summary, Dr. Scordilis testifies that no references (including Cabot) cited in his declaration discuss phase encoding of a harmonic phase relative to a fundamental phase for watermarking, and Cabot merely opens the door so that a person of ordinary skill in the art would “try to . . . explore further to develop a watermark” using harmonic phase coding data.

“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.

“wherein the ordering and annotation function is executed interactively at the time of each user query” contains two requirements: 1) how the function is executed (“interactively”) and when the function is executed (“at the time of each user query”). Petitioner, in effect, reads out of the claim the “interactively” requirement. Petitioner offers no persuasive reason as to why that is correct. See In re Wilson, 424 F.2d 1382, 1385 (CCPA 1970) (“All words in a claim must be considered in judging the patentability of that claim against the prior art.”). Petitioner, for its proposed claim construction of a single requirement, primarily relies on the Specification’s statement that “the ordering and Annotation step 345 is executed interactively, e.g., at the time of every user query.” Ex. 1001, 8:10–12; see Pet. Reply 12–13 (citing the same for the proposition that “[t]he ’676 patent specification also ties the terms together”); Tr. 16:3–12 (“it’s clear the specification is saying that interactively means at the time of every user query”). Petitioner’s reliance on this statement is misplaced. First, Petitioner agrees that the plain and ordinary meaning of “interactively” means “some sort of interaction with the system,” that the inventor did not utilize its own lexicography to redefine the term “interactively,” and that the Specification does not evidence a disavowal of claim scope. See Tr. 19:4–20. Consistent with that, Petitioner acknowledges that the quoted part of the Specification merely is an example, and is not defining “interactively” as limited to that example. See id. at 19:19–25. Second, Petitioner misreads the Specification as indicating that “at the time of every user query” is an example of “interactively.” See, e.g., id. at 21:25–22:1 (“the way I read this is at the time of every user query is modifying what interactively means”). Rather, the better reading of the Specification’s phrase “executed interactively, e.g., at the time of every user query” is that “at the time of every user query” (as opposed to some other time) is an example of when the function may be interactively executed, not that the two phrases on either side of the “e.g.” are synonymous. slip op. at 21

Nevertheless, Patent Owner retains compelling arguments for its proposed construction, supported by expert testimonial evidence, including dictionary definitions and the ’038 patent specification’s reference to a “portal or a gateway.” We find such references more compellingly refer to “portal” and “gateway” as synonyms rather than alternatives. In addition, Patent Owner provides convincing evidence and argument that rebuts the concern raised by the Board at institution whether Patent Owner’s proposed construction would exclude preferred embodiments.

“Because the above-quoted limitations of claims 1 and 12 plainly require that only a single copy of each data packet be forwarded to the output ports forming a subset (which according to limitations [1.1] and [12.1] forms a LAG), any position of Petitioner asserting the contrary must be contained in the Petition. 37 C.F.R. § 42.204(b)(3) (“the petition must set forth . . . [h]ow the challenged claim is to be construed.”). If not, Patent Owner is deprived of an adequate opportunity to respond, for example, by relying on expert testimony in a declaration to support its Response. Petitioner’s articulated claim construction position regarding forwarding only a single copy is belated, and no explanation has been provided to justify omission of this claim construction position in the § 42.204(b)(3). Thus, the argument is not entitled to consideration. Even if we do consider Petitioner’s belated claim construction position, it is nonetheless without merit and we are unpersuaded. Petitioner’s contention is based on the doctrine of claim differentiation, which disfavors reading a limitation expressly stated in a dependent claim into a claim from which it depends. See Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 910 (Fed. Cir. 2004).

“For several reasons, we are not persuaded by Petitioner that Borgione forwards only a single copy of a packet via the output ports of Borgione’s LAG as identified by Petitioner. Nowhere in the above-cited portions of Borgione is an indication that no other copy or replicated packet will be forwarded via the output ports of Borgione’s LAG. The above-cited description discusses one forwarding instance but does not represent that there is no other forwarding of a copied or replicated packet. To the contrary, the cited text indicates that other copies or replicated versions would still be forwarded via the output ports of the same LAG. Borgione describes that upon receipt of a packet with a multicast destination address, i.e., a multicast packet, a linking node such as node 110 identifies the network nodes subscribing to the multicast group and replicates the packet. Ex, 1006, 6:14–17. Borgione further states: “The replicated multicast packets can then be forwarded to the identified network nodes [such as node 120].” Id. at 6:17–18.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“First, the articulated motivation to combine is overly general and is disconnected with the circumstances and requirements of Devi. Mazzola discloses an address-translation mechanism using table look-up, as discussed above in Section II.D.3. It makes no mention of and is not concerned with aggregated links, sending a packet to just one port in an aggregated link, or load distribution among the ports in an aggregated link. It makes no distinction between one port and a plurality of ports, as it discloses that the index value retrieved from a table may be associated with either one port or a plurality of ports. Ex. 1007, 9:28–31 (“In response, the LTL translates the received index to a signal that selects a port or a group of ports for receiving the data frame.”). Although Mazzola describes that each port is associated with a unique index value and a VLAN “color” identifier (Ex. 1007, 3:12– 14), Mazzola also describes that “[t]he destination of any frame may be one or more ports” (id. at 6:16–17) and that a port can be a multicast port including a group of ports (id. at 6:20–24). The “efficiency” Mazzola mentions appears to be using a look-up table for address conversion versus not using a look-up table, and has little, if anything, to do with associating an FMID with a port versus associating an FMID with a group of ports or a LAG. Further, with Devi’s disclosure of sending only one packet to a LAG and load balancing among the ports in a LAG (limitation [1.2]), it is uncertain whether table look-up as described in Mazzola would even work in that environment. Petitioner does not address entries have to be revised. The statement of increased efficiency is speculative in the context of Devi. Second, Petitioner has over-simplified the issue with limitation [1.3] and has not adequately explained how Mazzola’s address-translation mechanism would be incorporated into Devi without affecting those portions of Devi relied on by Petitioner to account for limitation [1.2]. It is not adequately explained how Devi would be modified to incorporate teachings from Mazzola. Petitioner does not adequately address whether the proposed combination would impact Devi’s components and functionality that are also relied on by Petitioner. It is unclear why the purported combination would have been successful.” slip op. at 47
