    “on embodiments of Yeh with concentric sand screens having nine shunt tubes (six transport tubes and three packing tubes) (Yeh Figures 4A–B) and eccentric sand screens with four shunt tubes (two transport tubes and two packing tubes) (Yeh Figures 8A, 8C). See Pet. 32–37, 39, 41–43. Yet, Petitioner’s reasoning as to why “a higher-pressure shunt tube assembly necessitated greater wall thickness” rests on an unspoken one to one comparison between the shunt tubes of the different systems. See id.; see also Ex. 1003 ¶¶ 291–297 (Petitioner’s declarant comparing possible transport tubes of different pressure regions without considering or addressing any difference in the number of transport tubes). However, the embodiments relied on by Petitioner have different numbers of shunt tubes, and thus the greater wall thickness does not appear to be “necessitated” in the way inferred by Petitioner. Further, Petitioner’s analysis would seem to be most appropriate when comparing two concentric sand screens for different pressure regions, or two eccentric sand screens for different pressure regions. relies on Yeh’s teachings related to a horizontal well bore of 5000 feet for the “concentric screen → crossover tool → eccentric screen” arrangement, as well as, for why the concentric screen needs to be rated for a high pressure. Pet. 32–37, 39, 41–43. Petitioner also refers to these features for why one of skill in the art would combine the teachings of Yeh and Yeh2. Id. at 32. However, on cross-examination, Petitioner’s declarant agreed that it is concentric sand screens having a 6x3 shunt tube design that would provide the noted benefits of being rated for a higher pressure and being more robust (as relied on in the Petition), as compared to eccentric sand screens. Ex. 2013, 42:20–43:8; Sur-reply 4–5. This also exposes another issue with Petitioner’s arguments. Though Petitioner identifies that one of skill in the art would be aware that material choice, wall thickness, and pipe diameter all impact burst pressure of a pipe (Pet. 42 (citing Ex. 1017, 24 (Equation (14))), the Petition essentially ignores the fact that the claims do not require a single pipe in isolation. The claims require two shunt tube assemblies, each surrounding a base pipe within a wellbore. It is uncontested that a wellbore provides a confined space for such a system and thus any change in wall thickness of one pipe can result in a significant impact in the function of the other pipes. We find the testimony of Petitioner’s declarant (see, e.g., Ex. 1003 ¶¶ 290–297) unpersuasive when discussing wall thickness because it focusses on basic considerations of a standalone pipe, without sufficient consideration of the claimed completion assembly with its required pipe and tube structure.

Petitioner does not provide a citation to Yeh or a citation to where the Petition relies on the same number of shunt tubes between concentric and eccentric screens.

Thus, we decline to consider this late argument.4 See 35 U.S.C. § 312(a)(3) (requiring the petition to identify “with particularity . . . the grounds on which the challenge to each claim is based, and the evidence that supports the grounds”); 37 C.F.R. § 42.104(b)(5).” slip op. at 18

    “Thus, we agree with Petitioner that the combination of Yeh and Yeh2 teaches determining the shunt tube system operating pressures associated with the distal end of the production zone, but also more generally, determining the operating pressures along the entire production zone. With this knowledge of the system operating pressures, Petitioner argues that one of skill in the art would have selected eccentric screens for the distal end of the production zone “at any point at which the slurry pressure dropped below the pressure capacity of the eccentric screen shunt tubes.” Pet. 66 (citing Ex. 1005, 30:16–20; Ex. 1003 ¶ 388). In other words, knowing that the pressure decreases as you approach the toe, Yeh’s low-pressure rated eccentric screens could be used from some point prior to and covering the toe. determined pressure.” PO Resp. 37–38. We disagree. As discussed above, the record supports Petitioner’s position that one of skill in the art would have “understood the need to determine the shunt tube system operating pressure throughout the horizontal wellbore.” Ex. 1003 ¶ 383; see also Pet. 64–65. We find convincing Petitioner’s argument that one of skill with this understanding of the system pressures would select a shunt tube system rated to not only address the distal end, but also to address the needs of the adjacent region, so long as the pressure rating supported such a selection.

We start with an important observation: claim 18 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52, EPRC 1:32. One requirement of this apparatus is that it comprise “a semiconductor chip” (id. at 9:66) where “said semiconductor chip is a light emitting diode (LED) chip EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction (Resp. 14) of “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor LED chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 53 (quoting Ex. 1008, 10). Notably, claim 18 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim.

The record supports a construction very similar to the construction the District Court adopts, and we reference the District Court’s reasoning. Ex. 1024, 15– 18. We, thus, construe claim 18’s recitation that “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip that is capable of emitting light greater than about 40 milliwatts.” It is unnecessary to construe any other claim terms in this Decision because none of the parties’ disputes turn on the meaning of other terms.

    “The facts above are evidence of the Krames reference’s publication as of June 29, 2000, because the facts tend to make the Krames reference’s publication as of June 29, 2000, more probable than it would be without the evidence. See Fed. R. Evid. 401(a) (defining evidence as relevant “if it has any tendency to make a fact more or less probable than it would be without the evidence”). The evidence is sufficient to support publication. Meanwhile, no evidence of record suggests that Krames was not a printed publication as of June 29, 2000. Thus, a preponderance of the evidence supports Krames’s prior art status. Patent Owner argues that Ms. Watters “never establishes a firm date when Krames was purportedly available to the relevant public.” Resp. 21. Patent Owner bases this argument by taking a tortured reading of Ms. Watters’s statement that “[m]embers of the interested public could locate a copy of [the Proceedings] on or after June 29, 2000, the date it was catalogued.” Id. (quoting Ex. 1020, 3); see also Sur-Reply 12–13. The best understanding of Ms. Watters’s statement, in view of the context of Ms. Watters explaining the library’s cataloguing process, is that a member of the interested public had two options: the person could choose to locate the Proceedings on June 29, 2000, or the person could choose to locate the Proceedings after June 29, 2000.

    “In the Reply, Petitioner uses the Krames declaration (Ex. 1028) to argue, for example, that a person of ordinary skill in the art would have used a lower amperage than the 1.5 A dc that Patent Owner’s Response focuses on. Reply 8 (citing Ex. 1028 ¶ 22). This use of the Krames declaration is timely because it responds to an argument Patent Owner makes in the Patent Owner Response. 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in . . . patent owner response.”). As to relevancy and whether the Krames declaration is applicable to the facts of this case, the issues at hand are (1) whether or not a person having ordinary skill would have had reason to use the Krames LED with Begemann with a reasonable expectation of success and (2) whether or not the Krames LED is capable of outputting light at greater than about 40 milliwatts. Again, we emphasize that claim 21 does not recite a method where the LED within the recited semiconductor light source actually outputs greater than about 40 milliwatts. The Krames declaration is relevant to the facts of this case because the declaration has bearing on whether or not a person of ordinary skill in the art would have combined the Krames reference’s LED with Begemann’s lightbulb design. See, e.g., Ex. 1028 ¶ 22. Patent Owner argues that evidence must be relevant to motivation to combine “an LED chip from the Krames article (operating at 1.5 amps to produce 170 milliwatts of output)” but claim 21 has no “operating at 1.5 amps to produce 170 milliwatts of output” requirement. What is relevant is that Krames discloses a single chip that has the capability of outputting more or less light depending on operating conditions. Pet. Opp. 3; see also Ex. 1008, 8 (providing that Figure 12 of the Krames reference is described as illustrating “[l]ight output vs. current characteristic of a blue … 1x1 mm2 AlGaInN LED in a power package, compared to a conventional AlGaInN LED in a 5 mm lamp a package”). Because claim 21 does not require actually running the recited LED at any particular wattage or amperage, it is appropriate for the Krames declaration to rebut Patent Owner’s argument that a person of ordinary skill would not have considered using the Krames LED with Begemann at high amperage by explaining that a person of ordinary skill in the art would have considered using the exact same Krames LED with Begemann at a low amperage instead and that at this lower amperage the Krames LED would generate an amount of heat that would be easily dissipated by Begemann’s lamp while still providing an optical output of “greater than about 40 milliwatts” as recited by claim 21. Ex. 1028 ¶¶ 23–24 (citing Ex. 1008, 8). The fact that the Krames LED is configured to run at the high amperage if desired for a different application does not negate the rationale for combining the Krames LED to run at a lower amperage.” slip op. at 14

    “Patent Owner’s argument is unpersuasive because the Krames declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 21 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52. One requirement of this apparatus is that it comprise “at least one semiconductor chip” (id. at 10:1) where the “at least one semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts.” Id. at EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction of “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as meaning “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 54 (quoting Ex. 1008, 10). Notably, claim 21 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim. Petitioner never had a burden of establishing a method of running the Krames reference’s LED at this power output within a semiconductor light source.” slip op. at 12

    “We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’961 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 19. The prior art of record, for example, Begemann, likewise reflects “a hybrid of the light bulb art and semiconductor art.” Id. (quoting Pet. 28). Petitioner’s expert, Dr. Lebby, agreed that a person having ordinary skill in the art would need to be “familiar with thermal issues.” Ex. 2015, 26:15– 28:16. While Petitioner’s proposed description of a person having ordinary skill in the art could, in some instances, be sufficient to qualify a person as having ordinary skill, Patent Owner’s proposal is a more complete and accurate description of the level of skill commensurate with the scope of the challenged ’961 patent claims. Patent Owner’s description appears consistent with the prior art and patent specification before us and is supported by witness testimony. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). For the purpose of this Decision, we adopt Patent Owner’s description. We further note that the outcome of our decision would be the same under either party’s asserted skill level.” slip op. at 19

Id. (citing Ex. 2003, 15–18). Petitioner argues that the phrase “needs no construction” and that Petitioner’s grounds meet this construction. Reply 1–2.

    “The issue we have with Patent Owner’s contentions, as pointed out by Petitioner, is that Patent Owner does not establish persuasively how its claims require the “reversible open/close” feature and the “tactile feel features.” See Pet. Reply 27–29. Even presuming that these features did indeed drive tremendous commercial success and industry praise for the commercial products, Patent Owner does not adequately explain in its analysis how the claims of the challenged patent require these particular features that drive commercial success. Patent Owner seems to suggest that a break section in the control wire will fracture and that this feature in the commercial product relates to the tactile feel. PO Resp. 57 (citing Ex. 2029 ¶¶ 91–93) (“After the yoke has disengaged, if the handle spool is moved further proximally, a break section in the control wire will fracture, leaving the ball within the yoke and uncoupling the control wire from the distal components of the device.”). This “break section in the control wire” is not, however, claimed or covered in claim 1, the claim that purportedly embodies the commercial product. The claims alleged to cover the product do not specifically require any “tactile feel feature.”3 Likewise, while the claims may allow for an opening and closing of the clip assembly, there is no requirement in these claims that the clip assembly, as “demanded” by physicians, repeatedly open and close. Thus, both of the drivers of commercial success and industry praise are not commensurate in scope with the claims of the patented invention. See Ex. 1046 ¶¶ 23–29 (explaining how features are not claimed).” slip op. at 16

    “district court proceeding, Petitioner contends that “coupled to the sheath” means “slideable inside the sheath” and “the sheath confines the bushing.” Pet. 9. Petitioner provides no additional support. The district court tentatively rejected this broad interpretation. See Ex. 2003, 27–28 (“[T]he Court recommends that ‘coupled to the sheath’ be construed as ‘linked together, connected, or joined, but not slidable inside the sheath.’”). Patent Owner contends that Petitioner’s proposed construction of “coupled to the sheath” is “unreasonably broad,” but provides little citation to the intrinsic record before us. Prelim. Resp. 13–14. Instead, Patent Owner notes that the plain and ordinary meaning of coupled is “linked together, connected, or joined,” citing to an unrelated Federal Circuit decision as well as the related district court determination. Id. at 14; Ex. 2003, 28. In our proceeding, Petitioner has not provided persuasive evidence or argument to support its claim interpretation by merely pointing to what Patent Owner purportedly argued in district court. Based on the final record before us, “coupled to the sheath” means “linked together, connected, or joined” to the sheath. Our construction is consistent with the district court’s analysis and reflects the common understanding of the term “coupled” in the mechanical arts to require more than simply abutting or contacting. See generally Ex Parte Paul Robert Homrich, Appeal 2014-005786, 2016 WL 3541285, at *3 (PTAB, June 27, 2016) (“When used in mechanical systems, the plain and ordinary meaning of ‘coupled’ means to link together or connect,” and coupled requires more than contact or abut.).” slip op. at 10

    “We are not persuaded that Petitioner has demonstrated sufficiently that Adams discloses “a bushing extending between a proximal end coupled to the sheath,” (Ex. 1027, 17:4–5) as required by claim 1 of the ’371 patent. Based on the final record, Petitioner’s contention that retainer 110 [bushing] is slidable inside the sheath, or confined by the sheath, does not establish persuasively that the proximal end of the bushing is coupled to the sheath as required by claim 1. The claimed coupling must be “proximal coupling” and Petitioner can only point to distal coupling via distal tabs 118, 119 (Pet. Supp. Reply 6) – this is not “proximal” coupling. Further, for the bushing and the sheath to be coupled requires them to be “linked together, connected, or joined” in some manner and Petitioner has not established any such connection for proximal coupling. Petitioner also has failed to establish a persuasive reason for linking or connecting retainer 110 and sheath 112 – indeed, doing so would negatively impact the ability of retainer 110 to freely slide out of sheath 112. See Prelim. Resp. 27. Adams suggest that when control wire 108 is actuated and the clip is locked into the lock sleeve, retainer release 109 pulls retainer 110 back, disengaging retainer tabs 118, 119 from the two retainer holes as depicted in Figure 4.” Ex. 1023, 7:26–44 Finally, we note that our decision would not change if we adopted the district court’s claim interpretation. The district court adopted a claim construction of “a bushing extending between a proximal end coupled to the sheath” as “linked together, connected, or joined, but not slidable inside the sheath.” Ex. 2003, 28 (emphasis added). Should the district court’s interpretation be the correct one, Patent Owner’s position is much stronger whereas Petitioner’s theory is based on slidable movement. See Pet. 9 (arguing for “slideable inside the sheath” and “the sheath confines the bushing”); Pet. Supp. Reply 6. Having now considered the evidence in the complete record established during trial, we are not persuaded that Petitioner has demonstrated by a preponderance of the evidence that claim 1 would have been anticipated by Adams. Petitioner has not established persuasively that Adams discloses “a bushing extending between a proximal end coupled to the sheath.” For this reason, Petitioner has failed to prove by a preponderance of the evidence that Adams anticipates claim 1.” slip op. at 22

    “First, the above-reproduced figure does not appear in the Specification of the ’640 patent. Rather, it is a creation of the Patent Owner. The figure creates the impression that a “part” necessarily is a “device.” Patent Owner, however, does not provide adequate support for such a narrow reading of 14 “part.” Although a “device” is a “part” of a telecommunications network, that does not mean a “part” has to be a “device.” Even Dr. Akl, Patent Owner’s expert, testified only that a “device” is a “part” of a telecommunications network and not that a “part” of a telecommunications network has to be a “device.” Ex. 2006 ¶ 56. Second, the figure also creates the impression that neither a domain nor a region would identify a device. But Patent Owner does not provide adequate support for such a narrow reading of “domain” and “region.” In that regard, Dr. Akl, Patent Owner’s expert, testifies only that a “device” is neither a “domain” nor a “region,” not that a “domain” or a “region” would not or could not identify a “device.” Id. By assuming that a “part” of a telecommunications system has to be a “device,” and by assuming that neither “domain” nor “region” would identify one or more devices, Patent Owner sees an alleged contradiction in allowing media connectivity setting to be as we have construed it, and the phrase that immediately follows the claim term—“identifying one or more other devices.” Because of that alleged contradiction, Patent Owner contends that “at least one media connectivity setting identifying one or more other devices” should be construed as “information identifying one or more parts of a telecommunication network, distinct from either a domain or a region of the telecommunication network.”” slip op. at 14

    “Claim 10 recites, among other limitations, an additional requirement of determining from said bypass mode data that said media gateway “must” be bypassed in said media path. That is in contrast with the language of claim 9, which also depends from claim 8, and which recites, among other limitations, the additional requirement of determining from said bypass mode data that said media gateway “may” be bypassed in said media path. Neither Petitioner nor Patent Owner proposes an express construction for the word “must.” In the circumstances here, the plain and ordinary meaning of “must” in the English language applies. There is no indication that one with ordinary skill in the art would understand the word as conveying something different. The Specification of the ’640 patent does not set forth a special definition of “must.” Also, consistent with the plain and ordinary meaning of “must,” the Specification of the ’640 patent distinguishes between “must” and “may”: It may be determined from the retrieved bypass mode data that the media gateway may be bypassed in the media path, in which case preceding device connectivity data is included in the outbound communication setup request message. It may be determined from the retrieved bypass mode data that the media gateway must be bypassed in the media path, in which case preceding device connectivity data is included in the outbound communication session setup request message. Ex. 1101, 12:35–42 (emphasis added). 34 We determine that “must,” when applied to an action, such as bypassing a media gateway as recited in claim 10, eliminates not taking that action as a possibility and precludes the not taking of that action. In that regard, the different language used between claims 9 and 10 further supports the distinction between the absolute nature of “must” as used in claim 10 and the permissive nature of “may” as used in claim 9. In that regard, as is noted by Patent Owner, Petitioner’s witness, Mr. Bress, agrees that the permissive nature of “may” does not meet the absolute requirement of “must.” PO Resp. 43 (citing Ex. 2004, 123:7–124:5).” slip op. at 34

  • Skill levelDecided for patent owner

    “Level of Ordinary Skill in the Art Petitioner asserts: As of the priority date of the ’640 Patent of March 22, 2011, a person of ordinary skill in the art (“POSITA”) would have been someone with a Bachelor’s Degree in electrical engineering, computer science, or a related scientific field, and at least two years of work or research experience in the telecommunications industry, which could include telecommunications device design, telecommunications software development, or related areas. Alternatively, a POSITA in the relevant timeframe would have been someone with an advanced degree, such as a Master’s Degree, in electrical engineering, computer science, or a related scientific field, focusing on telecommunications technology. Alternatively, a POSITA in the relevant timeframe could have been someone lacking formal technical education but having experience in the 18 telecommunications industry that would be equivalent to such education. See Ex. 1004 at ¶ 128. Pet. 19–20. Patent Owner does not explicitly take a position on the level of ordinary skill in the art. We determine that no express finding on a specific corresponding level of technical education and experience is necessary, and that the level of ordinary skill in the art is reflected by the prior art of record.

    “49 media gateways. In that connection, we credit the testimony of Petitioner’s witness, Mr. Bress, over the testimony of Patent Owner’s witness, Mr. Akl, in part because Mr. Bress discusses and explains more of the disclosure of Ejzak. Patent Owner’s argument that it is possible to obtain the media connectivity setting of the ensuing device by requesting the ensuing device for such information (PO Resp. 38) is ineffective with respect to claim 4, which does not specify from where the information is retrieved. Retrieving information from the ensuing device nonetheless still is retrieving. With respect to claim 5 which requires retrieving the information from within the given media gateway, not the ensuing device, we have determined that Petitioner has not stablished that Ejzak necessarily discloses retrieving such information from within the storage of the given gateway. Patent Owner’s argument that the claim limitation of “retrieving ensuing device connectivity data for an ensuing device” would not have been regard by one with ordinary skill in the art as an obvious variant of Ejzak’s determining the IP realm for the next segment of the media path is not supported by sufficient reasoning and explanation directed to Ejzak’s disclosure of provisioning IP realms of media gateways as identified and explained by Petitioner. Between the testimony of respective expert witnesses of Petitioner and Patent Owner, we credit the testimony of Mr. Bress, Petitioner’s witness, over that of Mr. Akl, Patent Owner’s witness. Mr. Bress’s testimony, in our view, is more thorough, whereas Mr. Aky’s testimony, in our view, focuses more on what a prior art 50 disclosure literally states without enough explanation as to the understanding by one with ordinary skill in the art of the teachings associated with that language.” slip op. at 49
