“The level of skill is uncontested. Patent Owner adopts the level of skill identified by Petitioner as: [at] the time of the alleged invention in 2018, a POSITA[2] would have had a B.S. degree in mechanical or petroleum engineering or a similar technical discipline, with at least five years of experience in oil or gas well drilling, completion, and/or subsurface production operations or in technical support of such operations including at least some experience in unconsolidated formations utilizing sand control methods and means.

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. The deposition cited by Petitioner discusses Yeh at column 16, lines 26 through 35. However, the Petition does not cite or rely on these teachings of Yeh. 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.

“benefit of the filing date of an earlier filed application only if the disclosure of the earlier application provides support for the claims of the later application, as required by 35 U.S.C. § 112.” In re Chu, 66 F.3d 292, 297 (Fed. Cir. 1995) (citing 35 U.S.C. § 120). Section 112 requires, inter alia, that the specification contain a written description of the claimed invention. 35 U.S.C. § 112(a). In determining whether the written description requirement is met, we consider “whether the disclosure of the application relied upon reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). This analysis requires “an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” Id. Thus, “the level of detail required to satisfy the written description requirement varies depending on the nature and scope of the claims and on the complexity and predictability of the relevant technology.” Id. For example, the analysis must consider “the existing knowledge in the particular field, the extent and content of the prior art, the maturity of the science or technology, [and] the predictability of the aspect at issue.” Id. (alteration in original) (quoting Capon v. Eshhar, 418 F.3d 1349, 1359 (Fed. Cir. 2005)). “While a prior application need not contain precisely the same words as are found in the asserted claims, the prior application must indicate to a person skilled in the art that the inventor was ‘in possession’ of the invention as later claimed.” PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008) (citations omitted); see also Purdue Pharma LP v. Faulding Inc., 230 F.3d 1320, 1323 (Fed.

However, “it is the specification itself that must demonstrate possession. And while the description requirement does not demand any particular form of disclosure . . . , a description that merely renders the invention obvious does not satisfy the requirement.” Ariad, 598 F.3d at 1352 (citations omitted); see also Lockwood v. Am. Airlines, 107 F.3d 1565, 1572 (Fed. Cir. 1997) (“While the meaning of terms, phrases, or diagrams in a disclosure is to be explained or interpreted from the vantage point of one skilled in the art, all the limitations must appear in the specification. The question is not whether a claimed invention is an obvious variant of that which is disclosed in the specification.

The person of ordinary skill in the art is a hypothetical person presumed to have known the relevant art at the time of the invention. In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995). In determining the level of ordinary skill in the art, we may consider certain factors, including: “(1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field.” Best Med.

“Initially, we note that, although Petitioner presents a definition for “traction” in its Reply (see Pet. Reply 10), Dr. Morellas agreed with Patent Owner’s proposed interpretation during his deposition: Q. What would a person having ordinary skill in the art understand the word “traction” to mean? A. It would mean the grip that the -- that the tire has with the road. Q. So when the tire is gripping the road, the vehicle will have traction; correct? A. Correct. Q. But if the wheels are spinning freely and not gripping the road, the vehicle has no traction; correct? A.· Correct. Ex. 2031, 36:8–17. Accordingly, we adopt Patent Owner’s interpretation of “traction” to be a measure “of the friction between the vehicle’s drive wheels and the road surface” such that “a vehicle’s wheels have ‘traction’ when wheel rotation acts to propel the vehicle along the roadway” and “[t]he vehicle’s wheels lose ‘traction’ when they spin freely relative to the road and thus are no longer acting to propel the vehicle along the roadway.” See PO Resp. 27; see also Tr. 18:4–5 (Petitioner’s counsel stating that “the ultimate disposition doesn’t matter which definition [of ‘traction’ the Board] adopt[s]”).” slip op. at 24

“require the Enumerated Current Conditions to be determined by analyzing data from the Enumerated Sensors, and it is this claimed invention for which the specification must provide written description support. 35 U.S.C. §§ 112(a), 120. Although, as discussed above, the claim requires only one Enumerated Sensor and one Enumerated Current Condition, it additionally requires that data from the sensor be analyzed to determine the current condition. Thus, to support the full scope of the claims, Koebler must disclose that each of the Enumerated Current Conditions is determined by analyzing data from one of the Enumerated Sensors. Although Petitioner asserts that Koebler does not provide written description support for ten of the Enumerated Sensors (see Pet. 10–11), Petitioner focuses its arguments on three of the current conditions (moisture, an amount of vibration, and traction) (see id. at 15–20), and we likewise focus our analysis on these three current conditions.

Furthermore, having determined that the ’700 patent is entitled to an effective filing date of Barsoum ’777, which is June 5, 2008, the asserted March 2019 date of ATSC327 does not qualify it as prior art to the ’700 patent.

“POSITA to reasonably combine Emma with a smoke sensor reference.” Prelim. Resp. 44. We agree that Emma does not disclose a smoke sensor, but Petitioner has provided other prior art references, namely Butt and Smith, and presented several reasons, namely safety reasons, that a person of ordinary skill in the art would consider adding a smoke detector from Butt and Smith to Emma’s microwave oven. Pet. 24, 74–75. Obviousness is not determined from the perspective of the inventors or authors of a single prior art reference. Rather, obviousness is determined from the perspective of a hypothetical person having ordinary skill in the art. It is only that hypothetical person who is presumed to be aware of all pertinent prior art. Standard Oil Co. v. American Cyanamid Co., 774 F.2d 448, 454 (Fed. Cir. 1985). Petitioner argues, for instance, that Butt teaches the fire safety aspects of “a controller for interrupting a supply of electricity to an appliance upon detection of a trigger, such as [s]moke.” Pet. 24 (quoting Ex. 1015, 1:16– 18). Dr. Horenstein testifies that from a safety perspective, a person of ordinary skill in the art would have “combine[d] the additional kitchen-safety appliance features of Butt with the Emma microwave/refrigerator so as to enable the Emma microwave to shut down upon the detection of smoke, and to reenable the Emma microwave for a further cooking session when the smoke had cleared.” Ex. 1023 ¶ 124. Where Butt arguably discloses a smoke detector external to an appliance, Dr. Horenstein testifies that a person of ordinary skill in the art would have looked to “Smith to include the smoke sensor in operative connection with the microwave oven with the reset functionality disclosed by Butt for the added benefit of reusing the microwave oven.” Id. ¶ 127 (emphasis added). each directed towards shutting down a component of the device in response to a sensor output indicative of an unwanted condition.” Id. ¶ 127. Dr. Horenstein testifies further that a person of ordinary skill in the art “would have combined the elements as disclosed by known methods for the purposes of modifying Emma’s microwave / refrigerator combination to include Smith’s smoke sensor to be operatively connected with its cooking area and to include Butt’s smoke sensor and reset functionality.” Id. ¶ 126. Dr. Horenstein explains that inclusion of Butt’s reset functionality with Smith’s smoke sensor operatively connected with the cooking area into Emma would result in such elements merely performing the same function as they do separately, i.e., sensing smoke to withdraw electrical power from an electrical cooking appliance and then re-enabling the electrical cooking appliance. Id. Moreover, Dr. Horenstein testifies that the prior art, for example, Butt, specifically recognized the need to solve the problem of fires in the home started by cooking appliances. Id. ¶ 128 (citing Ex. 1015, 1:22–44). Butt explains, that “[h]ome fires are a serious problem in the United States. The National Fire Protection Association reports that between the years 1999- 2002, for example, there were 114,000 reported home fires associated with cooking alone.” Ex. 1015, 122–25.

“level of smoke” Neither Patent Owner nor Petitioner indicate that any claim terms require express construction. See Petition 13–14; Prelim. Resp 5. However, Petitioner contends that for the phrases “level of smoke” and “amount of smoke,” recited in claims 1, 15, and 24, it has “applie[d] what it understands Patent Owner contends is the meaning of this term in this Petition[,] and shows below the claims are invalid under Patent Owner’s construction.” Pet. 13–14 (citing Ex. 1009, 6). Patent Owner argues that it has “does not offer a special definition” and “asked the [district] court to give these terms their plain and ordinary meaning.” Prelim. Resp. 5, n 2. Patent Owner explains that a person of ordinary skill in the art “would similarly understand ‘level of smoke’ when read in the full context of the intrinsic record.” Id. For purposes of this Decision, reading the plain language of the claims in light of the specification, we understand “level of smoke,” or amount of smoke, in the claims generally as a predetermined level of smoke “indicative of a dangerous condition” as the specification of the ’745 patent explains. Ex. 1001, 15:48–49, see also id. at 16:1–2 (The ’745 patent describing “[t]he determination of a level of smoke corresponding to a dangerous condition.”).

Rather, obviousness is determined from the perspective of a hypothetical person having ordinary skill in the art. It is only that hypothetical person who is presumed to be aware of all pertinent prior art. Standard Oil Co. v. American Cyanamid Co., 774 F.2d 448, 454 (Fed. Cir. 1985). Petitioner argues, for instance, that Butt teaches the fire safety aspects of “a controller for interrupting a supply of electricity to an appliance upon detection of a trigger, such as [s]moke.” Pet. 24 (quoting Ex. 1015,1:16– 18). Dr. Horenstein testifies that from a safety perspective, a person of ordinary skill in the art would have “combine[d] the additional kitchen-safety appliance features of Butt with the Emma microwave/refrigerator so as to enable the Emma microwave to shut down upon the detection of smoke, and to reenable the Emma microwave for a further cooking session when the smoke had cleared.” Ex. 1023 ¶ 124. Where Butt arguably discloses a smoke detector external to an appliance, Dr. Horenstein testifies that a person of ordinary skill in the art would have looked to “Smith to include the smoke sensor in operative connection with the microwave oven with the reset functionality disclosed by Butt for the added benefit of reusing the microwave oven.” Id. ¶ 127 (emphasis added).” slip op. at 38

“Under the present record, we determine that Petitioner has satisfied its burden with respect to a lack of written description support for at least some of the claims. In particular, each of claims 3, 13, and 23 require QAM-16, QAM-64, QAM-256, and QAM-1024 constellations, and the beginning end points of the code rate ranges appear to have been selected for different reasons, without any discussion or support that would apply across the board. For example, Patent Owner argues that for the QAM-16 and QAM-64 constellations the first identified code rate that covers an unequally spaced constellation is important because that was “the object of the invention” and thus establishes the beginning end point. Id. at 46–47, 49–50. However, Patent Owner provides no reason why in the QAM-256 constellation the claimed range covers equally and unequally spaced constellations. See id. at 52 (locus plot of Figure 14c). Rather, Patent Owner merely asserts that the claimed range is “coextensive with the values in [the table of] Figure 15b.” Id. at 51. For the QAM-1024 constellations Patent Owner also asserts that the claimed range is “coextensive with the values in [the table of] Figure 17b,” and again makes no mention of unequally spaced constellations. Id. at 53. Not only is Patent Owner’s logic applied inconsistently across the different types of QAM constellations, but this also results in inconsistency in the logic behind claims 3, 13, and 23 which require all of the different types of QAM constellations. Thus, we preliminarily determine that Petitioner has shown that a person of skill in the art would not understand that the patentee had possession of the claimed invention of claims 3, 13, and 23 at the time of the application, as there does not appear to be a way in Barsoum for determining how to select the beginning end points of the code rate ranges. See Pet. 3 (citing Lizardtech, Inc. v. Earth Res. Mapping Inc., 424 F.3d 1336, 1345 (Fed. Cir. 2005)). Claims 2, 12, and 22 each only require a QAM-16 constellation and do not require the other QAM constellation types. Thus, these claims are not internally inconsistent in how they select the beginning end point of the code rate range. We determine, in view of the current record, the written description support for these claims is a close issue, as is the question of whether the disclosed locus plots, without more, are sufficient to disclose a range, rather than just specific points. As we have determined that claims 3, 13, and 23 have been shown preliminarily to lack written description support, we reserve these questions for trial.” slip op. at 13

Apart from the written description support arguments above, Patent Owner does not contest Petitioner’s obviousness analysis of the challenged claims. See generally, Prelim. Resp. We note that it would seem inconsistent for Patent Owner to argue that Barsoum has written description support for the claims and yet does not teach a feature of the claims. At the same time, Patent Owner also does not address ATSC322 or ATSC327, or Petitioner’s reasons to combine the references.

See e.g., id. at 54 (reproducing Ex. 1023, Tables 6.12 and 6.13 at 30–31 which show all four constellations with a code rate of 7/15). Petitioner also provides a number of reasons why one of skill in the art would look to ATSC322, which is a technical standard, for combination with Barsoum. Id. at 37–39. After review, we determine that the Petition preliminarily establishes a reasonable likelihood that claims 3, 13, and 23 are obvious over the combination of Barsoum and ATSC322.

Such a component is described by the ’400 patent as the RFID tag. See Ex. 1006, Fig. 5 (element 74).

Ex. 1001, 21:41–43, 22:38–40. Nothing in the ’773 provisional hints that anything, be it a tag or generic device, is attached to its otherwise disclosed key; therefore, we cannot agree with Patent Owner’s arguments. See generally Ex. 1005. The ’773 provisional merely indicates that a key can be contained in, removed from, and replaced in a key container module that can somehow sense the key’s presence, but provides no description as to how this sensing is accomplished, and certainly does not describe that anything attached to the key allows this sensing.

“[W]hen a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR, 550 U.S. at 416. This is the case here where Mosgrove’s wireless communication system exists already and is merely redirected. “[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” Id. at 417. Further, “any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements [of the prior art] in the manner claimed.” Id. at 420. This is the case here where the techniques of Harold illuminate an advantage to be had using Mosgrove’s existing system (or a slightly modified Mosgrove system). We find a reason existed to combine and modify the prior art: efficiency and streamlining. See Dystar Textilfarben Gmbh & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006) (making things stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient are universal motivators to combine/modify prior art). And, as Mosgrove’s disclosed key containers have wireless communication capability, simply specifying that the communications will be between the key container and the computer rather than between the key container and keypad is no technological leap. It would have required only the use of known components and techniques to yield predictable results, and we find there would have been a reasonable expectation for success.
