The Federal Circuit rendered its Decision on October 6, 2023 (Paper 58) and entered its mandate on November 29, 2023 (Paper 57). In its Decision, the Federal Circuit vacated our conclusion regarding the “means for detecting” limitation recited in claims 5 and 10. Sisvel, 82 F.4th at 1364, 1370. The Court ordered that, on remand, we “must conduct the analysis appropriate for Noah group two, including whether any of the protocols are clearly linked or associated with ‘the function recited in the claim,’[ ] and whether they are ‘adequate structure for performing this function.’” Id. at 1370 (citing Noah Systems, Inc. v. Intuit Inc., 675 F.3d 1302, 1313 (Fed. Cir. 2012)). The Court further held that “the Board should have considered the knowledge of a skilled artisan,” and specifically, Dr. Kakaes’s expert testimony, “to assess whether the protocol name sufficiently discloses an understood algorithm corresponding to the means-plus-function limitation.” Id. at 1369. The Court also held that we “must either (1) determine whether the claim[s] [are] indefinite and then whether such indefiniteness renders it impossible to adjudicate a prior-art challenge on the merits, or (2) resolve the prior art challenge to the patentability of the claims despite the potential indefiniteness of the means-plus-function term.” Id. at 1370. After the Federal Circuit issued its mandate, we ordered the parties to brief these issues including “the supported construction of the ‘means for detecting’ claim term, as well as the attendant patentability issues of indefiniteness and impossibility as relevant to this claim term.” Paper 59, 3.

    “For example, with respect to the CRC protocol, Dr. Kakaes testifies that “CRCs are often referred to as ‘error detecting codes’ as they are typically used[] to detect whether a received data message is or is not erroneous.” Ex. 1002 ¶ 88. Dr. Kakaes further testifies that [t]o use a CRC, the transmitter runs a polynomial division of the data block (before forward error correcting code has been applied, if any) to calculate a “remainder” consisting of a predetermined number of bits, for example 16, which are also called “parity bits,” or “check bits,” or “checksum bits,” or “CRC bits” that are attached to the block to be encoded and then transmitted, in whichever way it may or may not be encoded, punctured, etc. After reception and channel decoding (recall that means determining the “maximum likelihood” message), the receiver then runs the same polynomial division of the received decoded data block (which includes the parity bits) and, if the result does not match the “remainder,” i.e., the “parity bits” are not consistent with the determined message, the decoded data block “fails” the “check,” i.e., is declared as being erroneous. As it turns out such a determination is never wrong. In other words, the “false negative” rate is 0. Id. (emphasis added).

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

    “[t]he words of a claim are generally given their ordinary and customary meaning as understood by a person of ordinary skill in the art when read in the context of the specification and prosecution history.” Thorner v. Sony Comput. Entm’t Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012) (citing Phillips, 415 F.3d at 1313). “There are only two exceptions to this general rule: 1) when a patentee sets out a definition and acts as his own lexicographer, or 2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution.” Id. (citing Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1580 (Fed. Cir. 1996)). Neither of those exceptions apply here, and for the reasons below, we disagree with Patent Owner that the plain and ordinary meaning of “selecting a filter to apply” excludes determining whether or not to apply a given filter. We begin with the claim language at issue. TQ Delta, LLC v. DISH Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). When considering the language of the claim overall, the usage of “selecting a filter” in the claims does not in any way indicate whether the filter has to be selected from among multiple filters. Claim 1 recites “selecting a filter to apply to determined level of detail.” Ex. 1001, 13:20–22 (emphasis added). Patent Owner argues that “the claim language confirms that ‘selecting a filter’ means choosing from a number of alternative filters, not merely deciding whether or not to apply a filter,” (PO Resp. 34), but we see nothing in the claim language that suggests such a requirement. Patent Owner also points us to claim 19, arguing that selecting is not merely deciding whether to apply a filter, “since that determination is already made in [c]laim 19 by virtue of the initial sub-step of ‘exceed[ing] the threshold.’” Id. Again, we see nothing in claim 19 that suggests the determination of the threshold being exceeded requires a specific manner of filter selection. Instead, similar to claim 1, claim 19 recites: “when the level of detail exceeds the threshold, selecting a filter to apply to predetermined pixels.” Ex. 1001, 16:8–9. Thus, we are not persuaded that the claim language necessarily requires selecting a filter from among multiple filters. slip op. at 14

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

    “because Vehviläinen performs additional analysis before selecting a moderate or high activity filter, it does not teach selecting from among multiple filters. As discussed above, we do not agree with Patent Owner’s claim interpretation, and even if we did, we are persuaded that a person of ordinary skill in the art would have easily modified Vehviläinen’s filter selection to use a single area, e.g., the smooth area of Figure 5A, and a decision branch based on the level of detail for that single area. Vehviläinen discloses that “increasing the amount of selection branches makes the system more adaptive to the nature of the blocking effect but also increases control logic.” Ex. 1004, 8:15–27. Vehviläinen states that “[a] good embodiment,” but of course, “the invention can be utilized with less than three branches.” Id. at 8:18–21. Dr. Bove testifies that a person of ordinary skill in the art “would have been motivated to reduce complexity and the required control logic by using fewer branches, as taught by Vehviläinen, including for example just one branch, particularly for applications running on performance-constrained platforms such as low-end computer processors or mobile platforms, which often had constraints on thermal dissipation, power consumption, and cost.” Ex. 1003 ¶ 120 (citing Ex. 1004, 11:7–22). He further testifies that a person of ordinary skill in the art “would have been motivated to determine the level of detail for just the ‘smooth’ area and then select the smooth filter, if the area is smooth, or the high-activity filter otherwise.” Id. Dr. Bove illustrates that modification with the following pseudocode: if ( IsSmooth (Figure_5A) == TRUE) { Select (SmoothFilter); } else { Select (HighActivityFilter); } Id. He further testifies that such a modification would have been obvious and well within [a person of ordinary skill in the art’s] level of skill, and [such a person] would have had a reasonable expectation of success given that [the] modification involves a simple reordering of elements taught by Vehviläinen, the fact that Vehviläinen expressly teaches the have had with these basic filtering and thresholding techniques. Id. On this aspect, we credit Dr. Bove’s testimony because it is based on the express teachings of Vehviläinen and addresses a straightforward modification in view of those teachings.” slip op. at 33

    “separate ‘reordering procedure,’ to which the timer is tied.” Id. (emphasis added). We agree that the cited evidence in Sachs more closely supports Petitioner’s position that the “timer is stopped when and because the missing PDUs are received,” and not after the occurrence of some additional step in which PDUs in the RLC buffer are shuffled into sequential order. Petitioner persuasively supports its position with, for example, its annotated version of Figure 5, reproduced above, which depicts that the T_reorder timer is stopped when out-of-order PDUs 3 and 4 are received––Sachs does not depict or describe an additional step of reshuffling occurring before the timer is stopped. Pet. 41. Patent Owner’s argument that Sachs teaches “a reordering procedure is performed before any other actions are taken” is unavailing because it is not supported by the cited evidence. In support of this argument, Patent Owner’s Declarant, Mr. Regis J. Bates, Jr., offers similar testimony that “the expiry of the timer in Sachs does not trigger a status report as in the ’396 patent, instead a reordering procedure is performed before any other actions are taken,” but does not explain why the reordering procedure takes place before “any other actions.” Ex. 2001 ¶ 53 (citing Ex. 1003, Figs. 4, 5, Abstract, 8:25–31, 9:11–15) (emphasis added). In his Second Declaration, Mr. Bates adds no further detail or explanation and cites the same portions of Sachs. Ex. 2006 ¶ 29. None of the cited portions of Sachs sufficiently supports a finding that Sachs teaches or suggests that “a reordering procedure is performed before any other actions are taken,” as Patent Owner contends and as Patent Owner’s Declarant testifies.

Limitation 1[c] can be triggered in response to one set of stimuli and limitation [d] can be triggered in response to a different set of stimuli as is shown in Sachs’s figures. In order for Petitioner to prevail, it need only show one of these mutually-exclusive claim limitations to satisfy the claim, as it contends. Petitioner persuasively shows that, under a first theory, with a first set of stimuli, the timer is stopped before it expires and limitations 1[a], 1[b], and 1[c] are performed as shown in Figure 5 of Sachs. Ex. 1003, Fig. 5. Under a second theory, with a different, second set of stimuli, the timer is allowed to expire and limitations 1[a], 1[b], and 1[d] are performed as shown in Figure 4 of Sachs.

In Petitioner’s annotated version of Figure 4, PDUs 3 and 4 are not received within the time period set by the T_reorder timer––as such, the T_reorder timer expires and a status report acknowledging PDUs up to 14 and negatively acknowledging PDUs 3 and 4 (i.e., indicating that PDUs 3 and 4 are missing) is sent.

In the present proceeding, even assuming, arguendo, that the record sufficiently supports a finding that a POSITA would have known of FEC, CRC, ARQ, and hybrid ARQ protocols, Petitioner has not shown that the specification of the ’561 patent discloses a sufficient algorithm, whether “as a mathematical formula, in prose, or as a flow chart, or any other manner that provides sufficient structure” for the “means for detecting,” including an algorithm for performing any one or more of these protocols. Noah, 675 F.3d at 1312. The ’561 patent discloses “means (224) for detecting a need for retransmission of the received coded data block,” “CCU [Channel Coding Unit] [that] is responsible for channel coding, including forward error coding FEC” as well as detecting the “[t]he need for retransmission . . . by an error errors occurring on the channel with sufficient certainty.” Ex. 1001, code (57), 2:25, 6:64–65, 7:54–59; see id. at Fig. 5, Step 508, 10:41–44.

Although the ’561 patent discloses examples of incremental redundancy protocols such as “hybrid FEC/ARQ (Forward Error Correction/Automatic Repeat Request), which uses error correction coding in order to decrease the number of retransmissions,” it does not present an algorithm for implementing the same.

The parties do not argue that the formulation of the level of skill in the art affects any issue in this case, and we maintain our adoption of Petitioner’s formulation, which we find to be generally consistent with the disclosures of the ’443 patent and the prior art, and which includes that “more education may substitute for industry experience or vice versa.”” slip op. at 9

Resp. 9–10. We agreed with Patent Owner that the specification’s description of a single length indicator that conveys both types of information and the arguments made during prosecution that the claims required a “single LI” or “the same length indicator” to include both types of information were sufficient to support a construction that required a single length indicator to include both pieces of information. See Decision 9. Although it did not propose a construction in the Petition, Petitioner now argues that “the claim language uses the indefinite article ‘a’ to modify ‘length indicator’” and that “[p]recedent is well settled that ‘an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising.’” Pet. Reply 5 (citing KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed. Cir. 2000)). While we agree with Petitioner that “a” may mean “one or more,” that simply means that the addition of more length indicators would not be excluded from the scope of the claim. Petitioner does not explain, and we do not see, how that affects the meaning of “length indicator” itself and, for the reasons argued by Patent Owner and adopted at institution, we maintain the earlier construction of “length indicator” as “a single length indicator that provides two pieces of information: (1) that a first data octet of the protocol data unit is a first octet of a first service data unit; and (2) that at least one other octet of the protocol data unit is the last octet of another service data unit.” See Decision 8; Prelim.

    “We also observe that, although Patent Owner characterizes this issue as one based on “teaching away” (see, e.g., PO Resp. 3; PO Sur-Reply 15– 16), the argument is not about teaching away because Patent Owner is not pointing us to any specific teaching in the prior art, or elsewhere, that would counsel against the proposed modification. Patent Owner is not arguing that something in the prior art disparages or discourages the use of one bit of an LI as a flag. Instead, Patent Owner is arguing that one of skill in the art would not pursue the Qualcomm approach because to do so would mean accepting other drawbacks that would flow from the use of the flag. In any event, we credit Patent Owner’s evidence that dedicating a bit of the LI for use as a flag would reduce the length that could be represented by the remaining bits of the LI and cause SDUs to be divided into more PDUs. See, e.g., Ex. 2005 ¶¶ 30, 32. However, the record also shows that use of the flag would provide a specific advantage, as described in Qualcomm. See Ex. 1006, 3; Ex. 1007 ¶ 253. This is the motivation advanced by Petitioner which, notably, Patent Owner does not dispute. We conclude that, even if Patent Owner is correct that the proposal in Qualcomm would reduce the permitted PDU size from 128 octets to 64, the change would merely be something a skilled artisan would need to weigh against the advantages that the Qualcomm technique would provide. Patent Owner may be correct that the reduced lengths would, in the end, render the modified system unsuitable for certain applications or for adoption in a standard. That would not, however, make the modification nonobvious, particularly where the exact change proposed in the combination was suggested by individuals working in the field, as evidenced by Qualcomm itself.7 The record shows that at least some of those working in the field, at the time of the invention, believed that the advantages of Qualcomm’s approach would outweigh the reduced lengths.” slip op. at 20

    “In TS25.322, the value “0000000” is a predefined, special value used to indicate that “[t]he previous RLC PDU was exactly filled with the last segment of an RLC SDU and there is no ‘Length Indicator’ that indicates the end of the RLC SDU in the previous RLC PDU.” See Ex. 1005, 36–37. However, although Qualcomm specifically contemplates implementing its flag scheme by “[r]e-arrang[ing] special LI values as they are now coded on less number of bits” (Ex. 1006, 4), the Petition did not argue a combination that includes modification of the special LIs for the independent claims. Instead, Petitioner relied on Qualcomm’s proposal to modify ordinary LIs that indicate the end of SDUs. See, e.g., Pet. 71–72 (describing and illustrating modification of the LI that identified the end of SDU 1: “[t]he green modified LI indicates that a first data octet of PDU is a first octet of SDU1 and another octet of the PDU is the last octet of SDU1”); Ex. 1007 ¶¶ 261–262. Petitioner’s argument with respect to these claims is thus not consistent with the argument it advanced for the independent claims from which these claims depend. Petitioner cannot reasonably rely on one type of prior art LI as the “length indicator” of claim 1, but then shift to a different type of prior art LI when addressing the very same “length indicator” recited in a dependent claim. Moreover, Petitioner fails to explain how or why the special LI “0000000” that is used to indicate the layout of the previous PDU could reasonably be used to also indicate the layout of the current PDU in which the LI appears. For example, if the previous PDU did not meet the condition identified by the “0000000” special value, then the LI would not appear in the next PDU even if that next PDU had a first SDU that ended in that PDU. For these reasons, Petitioner has not provided sufficient explanation or argument to establish obviousness of claims 6 and 21.9” slip op. at 28

    “the case law makes clear that “an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising’” unless an “extremely limited” exception applies. See Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016) (quoting KCJ Corp., 223 F.3d at 1356; Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342 (Fed. Cir. 2008)). Here, claim 1 recites the transitional phrase “comprising,” meaning it is open-ended, and, therefore, the usual meaning of “a” as “one or more” would have been expected absent an extremely limited exception. In considering whether an exception applies, our review of the ’515 patent fails to indicate that the patentee intended the phrase to mean anything other than the usual meaning of “one or more.” Patent Owner asserts that “[t]he plain language of the claim clearly indicates only a single [list] is used to list multiple assets” and quotes two portions of the Specification, which state “a list of assets that satisfies criteria” and “a list of assets to which a . . . device is granted access.” PO Sur-reply 12–13 (quoting Ex. 1001, 12:60–67) (citing Ex. 1001, 2:23–34, 3:1–5, 4:21–23, 17:59–66). Although claim 1 of the ’515 patent recites “assets” in the plural, we fail to see how that conveys that the term “a” would have been understood as limited to “one.” Notably, neither party has identified any inconsistency, in the claims or other portions of the Specification (including the portions quoted and/or cited by Patent Owner), resulting from construing “a” as “one or more.” And, we find that there is no reason why the claims could not be met under the construction of “a” as “one or more.” Thus, we find that the ’515 patent does not “evince [ ] a clear intent to limit a or an to one.” See Convolve, 812 F.3d at 1321 (internal quotations omitted). Accordingly, we construe the term “a” in “a list of assets” as “one or more” such that the phrase “a list of assets” means “one or more list of assets.” Considering next the phrase “the list of assets” recited in limitation 1[e], the parties do not dispute that the use of the term “the” means that “the list of assets” refers back to the one or more list of assets retrieved in limitation 1[d] and discussed above. See PO Resp. 1–2; see generally Pet. Reply; PO Sur-reply 5. Similarly, the parties do not dispute that the phrase “the filtered list of assets,” recited in limitation 1[e], refers back to the list of assets resulting from the filtering step of limitation 1[d].

First, Petitioner contends “the combination is the use of a known technique to improve similar devices because using the capabilities of a client device to choose appropriately formatted content was a well-known technique.” Id. Petitioner asserts that “implementing Marusi’s techniques for organizing multiple representations and choosing among them based upon a client device’s capabilities would predictably function in Pyle’s system, which similarly seeks to target video content based on particular client device types and parameters.” Id.

Third, with respect to Marusi’s databases, Petitioner contends “[t]he combination of Marusi’s databases to manage the data in Pyle’s system uses a known technique to improve similar systems.” Pet. 21. In particular, Petitioner asserts that one of ordinary skill “would have been motivated to combine Marusi’s database teachings with Pyle because Pyle teaches storing the same content in multiple, different representations.” Id. at 21–22 (citing Ex. 1004, 9:64–10:21).

    “We credit Mr. Wechselberger’s testimony that an ordinarily skilled artisan would have been motivated to combine the teachings of Rittmaster and Duvall with a reasonable expectation of success. Ex. 1011 ¶¶ 46–50. As Mr. Wechselberger explains, Duvall provides the details of how to select an advertisement from the stored advertisements using a duration indicator combined with other factors, such as location.

We do not credit Dr. Rhyne’s testimony that combining the teachings of Rittmaster and Duvall would have required a substantial redesign of Rittmaster. Ex. 2002 ¶¶ 90–92.11 Regarding this issue, Dr. Rhyne testifies: 11 In paragraph 90, Dr. Rhyne refers to the substantial reconstruction of Estese, but the reference to Estese appears to be a typographical error. This section of his declaration addresses the combination of Rittmaster and Duvall. Rittmaster would require fundamental reconstruction to incorporate Duvall’s content identification list information 122 because Duvall’s content identification list information 122 only identifies advertisement data already embedded in a data stream. Rittmaster teaches using time frames during which content such as an advertisement may be inserted. See Rittmaster at [0132]; Ex. 2001 at 33, lines 20–24. Like Estese, Rittmaster is a system where time frames or windows allow customization by interleaving location-based advertisements into the frame before delivering it to the recipient. Rittmaster at [0132]. To use Duvall’s content identification list information 122, which identifies advertisement spots that are already part of a media stream, would thus require replacing the frame structure of Rittmaster with a full media stream that could then be overwritten—or in the terminology of Duvall, “muted”—in specific locations when told to by content identification list information 122.” slip op. at 34

    “that a person of ordinary skill would have had “(i) an undergraduate degree in computer science, computer engineering, or similar technical field; and (ii) one to two years of experience in analysis, design, or development related to recommender systems and collaborative filtering, with additional education substituting for less experience and vice versa.” Pet. 6 (citing Ex. 1003 (Terveen Decl.) ¶¶ 22–24). Patent Owner contends the applicable level of ordinary skill in the art would have had “(i) a B.S. in Computer Science or a closely related field with three or more years of experience in either embedded systems or recommendation systems or (ii) at least an M.S. in Computer Science. Additional education or experience may serve as a substitute for these requirements.” PO Resp. 19 (citing Ex. 2001 (Pazzani Decl.) ¶ 24) (internal citations omitted).

    “We are also guided by the principle that we only construe claim terms if, and to the extent that, it is necessary. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). In the Petition, Petitioner proposes constructions for “implicit filtering” and “explicit filtering.” Pet. 8–9. Patent Owner does not dispute Petitioner’s proposed constructions. Prelim. Resp. 33. Patent Owner does not dispute Petitioner’s showing that the cited art teaches “implicit filtering” and “explicit filtering” as used in the context of the claims of the ’680 patent. See generally PO Resp. Thus, we do not discern any dispute between the parties regarding these terms. As construction of these terms is not necessary in order to resolve this proceeding, we do not explicitly construe these terms.” slip op. at 11

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “We do not agree. First and foremost, the Specification does not provide that this “metaphor” or “pictorial representation” is a limiting contrary. The Specification states: “While the library metaphor is a particularly useful personalized visualization of heterogeneous media, other useful visualizations are possible. Other possible visualizations include, for example, simple nested menus and an office and file drawer metaphor.” Id. at 5:11–15. Patent Owner does not explain, and we do not discern, how the alternative visualizations of “simple nested menus” or “an office and file drawer metaphor” support Patent Owner’s proposed construction. Second, the description of the “virtual library” metaphor in the Specification does not support Patent Owner’s proposed construction. With regard to that portion of Patent Owner’s proposed construction that provides “a personalized collection of information,” the same paragraph Patent Owner cites states, “The types of floors in the virtual library, the types of stacks populating each floor, and the specific media items on each of the stacks preferably are selected based on the user’s profile, although they may also be based on all of the information that is available to the metabrowser when the available information is a relatively small and manageable amount.” Ex. 1001, 3:10–15 (emphasis added). The alternative of displaying “all of the information that is available to the metabrowser,” as opposed to content “selected based on the user’s profile,” does not support limiting “virtual library” to require personalization.” slip op. at 13

Cir. 2003) (“Although a patent’s prosecution history is relevant to the claim construction analysis, any disclaimer of claim scope based on prosecution history must be ‘clear and unmistakable.’”)). Patent Owner does not argue or explain how or why the passages it quotes from the prosecution history constitute a clear and unmistakable disclaimer. See PO Resp. 21–22. These passages were used by the Applicant in its patentability arguments. See Ex. 1002, 124, 125, 151, 153. In response to these arguments, the Examiner found the Applicant was arguing unclaimed features of the invention. Id. at 177–178. The Examiner wrote: As per Appellant’s argument that a meta-browser is not an obvious variant of a browser, Appellant is arguing matter not explicitly claimed in the claims of the specification. Appellant further argues that the claimed invention involves searching a multitude of sources, where Rapaport[17] teaches searching the single source of the Internet. However, Appellant does not distinguish in claims what that [sic] a multitude of sources are searched in addition to the Internet. Applicant further argues that the meta-browser “preferably monitors for data events even if the user engages in other activities such as…” Appellant continues to argue features not claimed in the claims of the specification. As per Appellant’s argument that the virtual library of the claimed invention searches outside the scope of the Internet and is more than just a text-based search engine, Appellant is arguing features not claimed in the claims of the specification.
