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

    “We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

    “Finally, Petitioner explains in detail why and how a person of ordinary skill in the art would have had reason to combine the teachings of Carmel and Mattavelli, with a reasonable expectation of success.

Id. at 50, 52–53, 55. Petitioner contends that Carmel and Mattavelli are both directed to processing multimedia data playback “for the appreciation of a user,” while providing the highest perceived audio and video output quality possible in view of system constraints to ensure playback continuity.

Petitioner argues that Carmel and Mattavelli both pertain to compression of multimedia data using well-known coding and compression standards for video streaming. Id. at 51 (citing Ex. 1003, 7:25–26, 11:24–52; Ex. 1004, 2309–11). Petitioner further asserts that a person of ordinary skill in the art would have appreciated that Carmel and Mattavelli “complement[]” each other because Carmel addresses constraints on available network bandwidth and Mattavelli addresses limits on available processing resources at the client/multimedia player. Pet. 52 (citing Ex. 1003, code (57), 7:36–41; Ex. 1004, 2309–2312). According to Petitioner, an ordinarily skilled artisan would have been motivated to combine the complementary teachings in Carmel and Mattavelli to create a more robust streaming system that addresses both bandwidth constraints and client processing limits to provide the best possible playback experience. Id. (citing Ex. 1002 ¶¶ 212–215). Petitioner also contends that Mattavelli teaches that merely optimizing transmission bandwidth is not sufficient and is potentially harmful, which provides an express motivation to combine Carmel’s and Mattavelli’s complementary teachings to ensure that different, related links in the streaming playback chain are optimized together. Id. at 53 (citing Ex. 1002 express disclosure that would have motivated a person of ordinary skill in the art to incorporate Mattavelli’s complementary teachings regarding decoding because Carmel states that multimedia playback is achieved “preferably with only a minimal necessary transmission and decoding delay.” Id. at 53–54 (quoting Ex. 1003, 10:50–54; citing Ex. 1002 ¶ 218).

Patent Owner does not dispute Petitioner’s explanation of the level of skill in the art. See Ex. 2031 ¶¶ 15–16.

    “We begin with the claim language in view of the Specification, which weighs heavily against Patent Owner’s position that we should rewrite “computer system” as narrowly referring to a “computing device.” PO Resp. 24. As Petitioner notes, the ’872 patent’s Specification uses “computer system” to refer to a wide range of equipment, from a component of a computing device, to a whole computing device, to a collection of computing devices. Reply 9–10 (citing Ex. 1001, 4:5–8, 11:15–18, 16:50–55). In one example, the Specification refers to “one or more other computer systems (e.g., protected network devices 136).” Ex. 1001, 18:52–53. Thus, the Specification lists “protected network devices 136” as only an example of “other computer systems,” demonstrating that “computer systems” refers to things other than protected network devices. Although Patent Owner may be correct that this passage more than a single computing device,” we find that other disclosures in the ’872 patent do. Specifically, the Specification uses the language “distributed computer system” when referring to numerous components, including “protected network devices” and an “IDS/IPS system.” Ex. 1001, 3:26–28; Reply 10. In addition to showing that a “computer system” is not limited to a single computing device, this conveys that a “computer system” according to the ’872 patent can include an IDS/IPS.” slip op. at 14

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

    “Based on our review of the complete record, we find Petitioner’s arguments and evidence to be more persuasive. Patent Owner does not dispute Petitioner’s argument and evidence that capturing detailed information like Goel’s activity sources, activity targets, and association was recognized as enhancing threat analysis. Pet. 44 (citing Ex. 1003 ¶ 79); see PO Resp. 55–59; Sur-Reply 15–17. Additionally, contrary to Patent Owner’s suggestion, we find that the Petition does not propose incorporating Goel’s kernel hooks into Capalik’s system. See Pet. 41–46. Patent Owner contends that the Petition’s reference to modifying Capalik by “adding lines of code” suggests implementing the code disclosed in Goel include kernel hooks. Id. Notwithstanding Patent Owner’s assertion otherwise, this is an unpersuasive bodily incorporation argument, as the Petition never says an ordinarily skilled artisan would have used the exact lines of code from Goel in Capalik. Rather, the Petition says that an ordinarily skilled artisan would have had sufficient skill to implement straightforward code modifications to identify activity sources, targets, and associations: a [person of ordinary skill in the art] would have understood that modifying Capalik’s system (e.g., Linux-based) to additionally monitor, identify, and store each individual activity of an attack including “activity sources, activity targets, and associations” would have required straightforward modifications to programs/code instructions, which would have been well-within the skillset of a [person of ordinary skill in the art]. Pet. 46. Patent Owner argues that Petitioner does not explain how an ordinarily skilled artisan would have modified Capalik without using kernel hooks. Sur-Reply 17. But Patent Owner does not cite any evidence to counter Dr. Jakobsson’s testimony that an ordinarily skilled artisan would have had the skill to apply Goel’s general teaching of identifying sources, targets, and associations to Capalik’s system. Ex. 1003 ¶ 182. On the whole, the evidence does not support Patent Owner’s position that the combination would have required substantially increased detection risk. Moreover, even if the combination would have somewhat increased detection risk, Petitioner persuades us that an ordinarily skilled artisan still would have had reason to combine the references teachings. Patent Owner’s allegations of increased detection risk do not negate the undisputed evidence that the combination would have provided the advantage of improved threat analysis. Pet. 44 (citing Ex. 1003 ¶¶ 175–182). Ultimately, Patent Owner’s that activity logging be undetectable.” PO Resp. 56 (emphasis added) (citing Ex. 1004 ¶ 6). This exaggerates Capalik’s disclosure. Although the cited paragraph suggests that certain systems unfortunately may be detectable by some users, it does not convey that it is a requirement for the system to be categorically undetectable. See Ex. 1004 ¶ 6.8 In sum, Petitioner persuades us by a preponderance of the evidence that it would have been obvious to modify Capalik “to identify and store unauthorized activities including the activity source, activity target, and association of each activity.” Pet. 41–46; PO Resp. 55–59; Reply 20–22; Sur-Reply 15–17.” slip op. at 47

  • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for patent owner

    “arguments and evidence, we determine that Patent Owner fails to sufficiently show a nexus between any of its objective indicia evidence and the claimed invention. See Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (“The patentee bears the burden of showing that a nexus exists”). A showing of sufficient nexus is required to establish that the evidence relied upon traces its basis to a novel element in the claim, not to something in the prior art. Institut Pasteur & Universite Pierre Et Marie Curie v. Focarino, 738 F.3d 1337, 1347 (Fed. Cir. 2013). Objective evidence that results from something that is not “both claimed and novel in the claim” lacks a nexus to the merits of the invention. In re Kao, 639 F.3d 1057, 1068 (Fed. Cir. 2011) (emphasis omitted). Thus, establishing nexus involves a showing that novel elements in the claim, not prior-art elements, account for the objective evidence of nonobviousness. Id. As discussed above, Petitioner shows that Capalik teaches all limitations of claim 1. Petitioner persuades us that none of claim 1’s elements individually nor any combination thereof is novel over Capalik’s disclosure. Accordingly, claim 1 is not novel over Capalik, which disproves Patent Owner’s assertion of nexus. PO Resp. 73–76. Moreover, even if claim 1 were novel, Patent Owner otherwise fails to show nexus for its commercial success, praise, or copying assertions. Patent Owner’s evidence does not show that Petitioner’s commercial product embodies claim 1.

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 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

    “defined stoichiometry” (Ex. 2037, 527) but the word may also be a “generic term for phases . . . which may have a narrow or extended compositional stability range” (id.). The first glossary meaning is consistent with Patent Owner’s position. The second, broader, glossary meaning is consistent with Petitioner’s position. Some of the extrinsic sources before us support the broad definition, and some support the narrow definition. See PO Sur-Reply 3–4 (arguing that Dr. Miles admitted that various treatises distinguish intermetallic compounds from alloys and solid solutions). Thus, neither Dr. Miles or Dr. Raabe is “wrong scientifically” in how they use the term “intermetallic” in this proceeding. Id. at 2 (noting that Dr. Miles agreed that Dr. Raabe’s construction is not wrong scientifically). As explained below, however, only one of these meanings is appropriate here. To decide which possible meaning applies to the ’227 patent, we focus on the patent claims and specification. Claim 1 indicates that the intermetallic layer has a “mean composition” (emphasis added). Ex. 1001, 15:1–10. This indicates, albeit weakly, that iron composition across the layer may vary rather than having ordered stoichiometry—consistent with Petitioner’s position. The specification also indicates that “intermetallic alloying” is a possibility—again, consistent with Petitioner’s position. Ex. 1001, 2:47–50. Meanwhile, nothing in the ’227 specification explicitly (or implicitly) suggests that “intermetallic layer” must be limited to elements atomically joined with defined stoichiometry in an ordered crystal structure. We also find that Dr. Miles’s testimony regarding the meaning of “intermetallic” is more credible than Dr. Rabbe’s testimony. Dr. Rabbe, in deposition, stated that Figure 2 of the challenged patent “does not show a layer that meets [his] construction of intermetallic.” Ex. 1078, 129:21–24. The ’227 patent, however, states that Figure 2 includes an “Al-rich Intermetallic layer.” Ex. 1001, Fig. 2, 3:60–64 (“FIG 2. Illustrates a coating … which does not correspond to the invention. This succession of layers (interdiffusion layer and intermetallic layer) yields inferior results in resistance spot welding.”). Also, Dr. Raabe previously referred to a layer of Takagi as having “intermetallic phase layering and structure.” Pet. Reply 4 (citing Ex. 1076 ¶ 166; Ex ¶ 1075, 17) (emphasis omitted). Thus, Dr. Raabe’s construction of “intermetallic” for this proceeding does not fully account for the ’227 patent usage of the word “intermetallic” and does not fully account for Dr. Raabe’s prior usage of the word “intermetallic.” Patent Owner argues that Petitioner’s construction “erases the meaningful distinction” between the claimed layers. PO Resp. 11. Patent Owner further argues that Petitioner’s construction renders the word “intermetallic” superfluous because allowing the intermetallic layer to be “merely a multi-element alloy erases the meaningful distinction among these layers.” Id. We disagree. The word intermetallic serves to require that the layer be composed of two or more metals or a metal and a metalloid. The word intermetallic also serves as a label to differentiate each of the four claimed layers. For example, in claim 1, the word “intermetallic” is used much like the words “interdiffusion” and “intermediate” to give each of the four layers (each having differently mean compositions) different labels.” slip op. at 16

In particular, Petitioner argues that Takagi discloses a pre-coating thickness of 10–20 µm but does not explicitly disclose a post hot-stamping coating thickness corresponding to the pre-coating thickness. Pet. 11. Cornette teaches that the hot-stamping thickness causes coating expansion from 25 µm to about 40 µm, an increase of 60%. Id. (citations omitted). Petitioner and Dr. Miles reason that, when hot stamping Takagi’s product, the thickness would be 32 µm. Id. (citing Ex. 1003 ¶ 32); see also Pet. Reply 20–21. Thus, Patent Owner argues that Cornette evidences Takagi’s finally coating thickness without requiring modification of Takagi. Petitioner further argues that Takagi and Cornette teach that post hot- stamping thickness could be varied and optimized as a result effective variable. Id. at 12–13; see also Pet. Reply 17–18. Cornette teaches, for example, that “[t]he average [pre-coating] layer thickness showing the best compromise between corrosion protection and weldability is 25 µm” and links this pre-coating thickness to a final thickness of “about 40 µm at the steel surface.” Ex. 1014, 9. Petitioner also argues that it would have been obvious to fill in other details of Takagi including, for example, selecting USIBOR 1500 steel, based on the teachings of Cornette. Pet. 14. Patent Owner argues that there is no reason to combine Takagi with the teachings of Cornette. PO Resp. 26. Patent Owner makes seven related arguments. Patent Owner first argues that the Petitioner’s position is speculative and lacks basis. Id. at 26–27. We disagree. Cornette evidences a final coating thickness for Takagi, and the references also suggest that final coating thickness is result effective. Second, Patent Owner argues that there would have been no incentive to seek a motivation to seek a thicker coating post-hot stamping. Id. at 28– 35. This argument does not undermine Petitioner’s position that Takagi, by itself, would have reached a thicker coating after stamping as evidenced by Cornette. Pet. 11–12. Petitioner takes the position, with evidence, that practice of Takagi alone would reach the recited thickness. No motivation to modify Takagi is required under this position.” slip op. at 25

  • ExcludeMotion to exclude, deniedDenied

    “IV. PATENT OWNER’S MOTION TO EXCLUDE Patent Owner seeks to exclude portions of Dr. Wieselthaler’s Declaration (Exhibit 1041), portions of Mr. Crosby’s Reply Declaration (Exhibit 1042), portions of the deposition transcript of Dr. Wieselthaler (Exhibit 2028), and the exhibits “upon which that testimony is based” (Exhibits 1015, 1038, 1044, 1046, 1049, and 1050). Mot. 1. According to Patent Owner, the Motion was made “to preserve objections previously made in the record.” Id. (citations omitted). Patent Owner did not timely move to strike any of the evidence at issue as being outside the scope of reply evidence. Patent Owner asserts that because an inter partes review must be based on prior art consisting of patents or printed publications (citing 35 U.S.C. § 311(b)), the testimony of Mr. Crosby and Dr. Wieselthaler concerning “various physical devices allegedly known” to a person of ordinary skill in the art is inadmissible, along with all of the exhibits (consisting of printed materials such a journal abstracts, press releases, and papers) related to those physical devices. Id. at 3–4; see also Mot. Reply 1–4 (arguing that “devices that Petitioner’s witnesses assert were in public use prior to the claimed inventions, are not prior art that can form the basis of an inter partes review”). According to Patent Owner, Dr. Wieselthaler was unable to “link two of these physical devices to the printed prior art asserted in this [inter partes review], but those attempts fell apart during his cross examination.” Id. at 4. Patent Owner further reasons that because the evidence “cannot be the basis” of an inter partes review, it “has probable,” “is irrelevant and not admissible,” “presents substantial danger of confusing the issues, causing undue delay, and wasting time in this trial,” and “are not ‘based on sufficient facts[,] the product of reliable principles and methods[, or] ‘a reliable application of the principles and methods to the facts of the case.’” Id. at 7 (citing Fed. R. Evid. 401–403, 702) (modification in original). With regard to Exhibits 1015, 1038, 1044, 1046, 1049, and 1050, Petitioner argues, and we agree, that Patent Owner identifies no plausible legal theory for their inadmissibility based on the contention that they discuss physical devices. See Mot. Resp. 3. We also agree with Petitioner that the exhibits are not “the basis for any ground” asserted in this proceeding, and may be properly relied upon by Dr. Wieselthaler and Mr. Crosby as support for their rebuttal testimony directed to Patent Owner’s arguments disputing Petitioner’s asserted motivation to combine the prior art relied upon in the instituted grounds.

    “‘electronics for power and control’”). According to Mr. Crosby, a person of ordinary skill in the art “would have understood based on the disclosure of this setup that these speed and motor parameters were monitored by a sensor providing feedback to the controller.” Ex. 1003 ¶ 725. Mr. Crosby identifies no support for this opinion, which we give little weight to. The mere fact that Bourque’s pump used software to control speed and motor parameters does not show that Bourque used “one or more sensors” to provide feedback signals to the external control unit. Indeed, Petitioner fails to identify any evidence that Bourque used any “sensor” to monitor “speed and motor parameters.” Mr. Crosby also states that “[e]ach of the ‘ultrasonic flow probe’ and the ‘solid-state catheter-type pressure transducer’ described in [Bourque] is a ‘sensor’ as recited in Claim 33 that provides feedback signals to the external control unit (e.g., ‘electronics for power and control’ and ‘data acquisition’).” Id. ¶¶ 581, 726. Mr. Crosby’s opinion is again unsupported by the evidence, because, as explained above, there is no teaching in Bourque that either the “ultrasonic flow probe” or the “pressure transducers” used in the “in vitro characterization” studies were part of the heart assist pump device. Based on our review and consideration of Petitioner’s arguments and evidence directed to claim 11, we find that Petitioner has not shown by a preponderance of the evidence that the asserted combination of Bourque and Wampler teaches or suggests each of the limitations of dependent claim 11. We reach the same conclusion for the same reasons with regard to claim 33.” slip op. at 48
