The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer. Based solely on the diagnostic test passage and the prosecution history, a possible interpretation may be that the operational parameter determination in claim element 1b encompasses the diagnostic testing in claim element 1c. That is, “performing a diagnostic test to determine whether the operational parameter is suitable for the three-dimensional printer” in claim element 1c is subsumed as part of “determining an operational parameter of a fabrication process using the three-dimensional printer based upon the data, the operational parameter including at least one of a build platform temperature, a build volume temperature, an infill requirement, a rafting requirement, a support structure requirement, and a cooling requirement” in claim element 1b.” slip op. at 15

“We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

“(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17.

Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

“We agree with the parties that a person of ordinary skill in the art would have understood the term “fact” to include an indication of truth, whereas an assertion need not include such an indication. However, we disagree with PARC that a person of ordinary skill would have considered the term “assertion” to exclude facts. Indeed, in its ordinary and customary meaning, a fact stored in a context graph would be a type of assertion. We appreciate PARC’s argument that when two different terms appear in a claim, they presumably refer to different things. See PO Resp. 27 (citing CAE Screenplates, 224 F.3d at 1317). And we agree that the two terms have different meanings in claim 1 based on the plain meaning of each term. However, the specification refers to “stor[ing] facts and assertions about a user’s behavior and interests,” which simply appears to identify a single category of data for storage, i.e., “facts and assertions,” without specifying a clear difference between “facts” and “assertions.” See Ex. 1001, 3:21–22. In any event, we find no evidence of record suggesting that either (1) the (citing Pet. Reply 8–9).

That claim 1 requires the presence of both “facts” and “assertions” does not render the two terms superfluous, as this would exclude prior art in which a context graph includes only assertions but not facts.

“content for output.” Id. at 89. We determine, however, that Petitioner’s argument under Step 2A Prong One that claim 1 is directed to the “obtaining content for output” is not substantially different from the Examiner’s determination that claims 1‒20 recite “collecting information, analyzing it, and displaying certain results of the collection and analysis.” Compare Pet. 37–88 (citing e.g. Electric Power), with Ex. 2001, 193–194 (also citing Electric Power). In both cases, the argument is the same or substantially the same, i.e., that similarly identified subject matter of the claim is obtaining (collecting) data and displaying (outputting) it. Nevertheless, as to Step 2A Prong Two, we determine that the claims at issue in the ’096 prosecution differ in material ways from the ’903 patent claims at issue in this PGR. Specifically, the ’096 patent claims recite a touchscreen interface not recited in the ’903 patent claims. Additionally, the ’903 claims focus on the “output device” as performing the patented steps but in the ’096 prosecution history the “‘information apparatus performs the patented steps and “is integral to the claims” (as the Applicant argued). See Ex. 2008 [comparison of ’096 prosecution claims and ’903 claims]; Ex. 2001, 150; see also Pet. 89 (“the claims at issue in the ’067 application were different than the claims of the ’903 patent addressed here.”). rejection and arguments in the ’096 prosecution history turns on whether the claims in this PGR recite different elements that must be determined to integrate the judicial exception into a practical application (i.e., Prong Two of Step 2A). Petitioner argues that an essential element different than the ’096 claims, i.e. the output device, does not integrate the judicial exception into a practical application because the claims do not amount to an improvement to computer functionality. Pet. 37–72. We find this a close case. Nevertheless, due to the differences in the claims, we determine that the Examiner’s withdrawal of the § 101 rejection in light of the applicant’s arguments regarding the claim being directed to a specific technical solution is not substantially the same argument that Petitioner’s presents in the Petition as to Prong Two of Step 2A.” slip op. at 22

“in the art at the time of the invention] would have understood that an output system/device could be (or include) an information apparatus. Prelim. Resp. 24. We determine that Patent Owner’s argument has a logical flaw––i.e., the fact that a particular device could be used alternately as an information apparatus or an output device does not necessarily mean that it was known by one of ordinary skill in the art to use a combined information apparatus/output device and have the new combined device perform all the additional functions required by the claims. “The knowledge of ordinary artisans may be used to inform what is actually in the specification, but not to teach limitations that are not in the specification, even if those limitations would be rendered obvious by the disclosure in the specification.” Rivera v. Int’l Trade Comm’n, 857 F.3d 1315, 1322 (Fed. Cir. 2017) (“Rivera”). “The question is not whether a claimed invention is an obvious variant of that which is disclosed in the specification . . . . It extends only to that which is 1997). Patent Owner has not pointed to any disclosure in the ’413 application teaching that an “output device” can perform the functions of the “information apparatus” including its interactions with the “output device.” For example, claim 1 recites “wirelessly receiving, by the output system . . . output data from at least one server of the one or more servers over the Internet.” Ex. 1001, 37:28–32. At this stage, we find sufficiently persuasive Petitioner’s argument, which we discuss above, that the only written description support for an “output device” that performs the claimed functions by accessing the Internet provided by Patent Owner is not an “output device” but an “information apparatus.” Prelim.

“Finally, the definition of output device in the priority ’765 Application (as in the Specification of the ’031 patent) is that an “[o]utput device [] is an electronic system capable of outputting digital content … Any device capable of playing or reading digital content in voice (e.g., music, speech) or data (e.g., text, document) is also a possible output device.” Prelim.

“Under 35 U.S.C. § 112(a), enablement is separate and distinct from the written-description requirement. Ariad, 598 F.3d at 1344. “The test of enablement is whether one reasonably skilled in the art could make or use the invention from the disclosures in the patent coupled with information known in the art without undue experimentation.” United States v. Telectronics, Inc., 857 F.2d 778, 785 (Fed. Cir. 1988). “[A] patent specification complies with the statute even if a ‘reasonable’ amount of routine experimentation is required in order to practice a claimed invention.” Enzo Biochem, Inc. v. Calgene, Inc., 188 F.3d 1362, 1371 (Fed. Cir. 1999). Whether undue experimentation is needed is not a single, simple factual determination, but rather is a conclusion reached by weighing many factual considerations. In re Wands, 858 F.2d 731, 737 (Fed. Cir. 1988). These factors, referred to as the Wands factors, include: (1) the quantity of experimentation necessary, (2) the amount of direction or guidance presented, (3) the presence or absence of working examples, (4) the nature of the invention, (5) the state of the prior art, (6) the relative skill of those in the art, (7) the predictability or unpredictability of the art, and (8) the breath of the claims. Wands, 858 F.2d at 737. It is Petitioner’s burden to show by a preponderance of the evidence that the claims of the ’989 patent lack enablement. 35 U.S.C. § 326(e). Petitioner’s evidence and argument does not sufficiently establish that the ’989 patent fails to teach those in the art to make and use the claimed invention without undue experimentation. See PO Resp. 58–66. The Petition does not address the Wands factors sufficiently so as to show that undue experimentation is required to make or use the claimed invention. For example, neither the Petition nor Dr. Pearce sufficiently addresses the state of the prior art or the relative skill of those in the art. See Pet. 64–65; Ex. 1002 ¶¶ 145–152; PO Resp. 62. As Patent Owner argues, this is an “omission[] that [is] particularly fatal” to Petitioner’s enablement argument, because Petitioner argues that mechanical expansion and inflation expansion are incompatible and cannot be combined. PO Resp. 62; see Pet. 30–38, 64. Dr. Grundfest, however, testifies that it was well known to combine mechanical and balloon-based expansion in surgical devices. Ex. 2005 ¶¶ 132–136; PO Resp. 56. During cross-examination, Dr. Pearce testified that he “thought about the state-of-the-art in minimally invasive surgery during the 1990s.” Ex. 2003 18:1–14. Dr. Pearce’s testimony is conclusory and does not sufficiently address whether he considered whether it was well known to combine mechanical expansion and inflation expansion in surgical devices. For another example, relying upon the testimony of Dr. Pearce, the Petition asserts that a redesign of the expansion design disclosed in the ’989 patent “would take a substantial amount of time and cost to achieve.” Pet. 65 (citing Ex. 1002 ¶ 149). Likewise, Dr. Pearce testifies, “[s]uch a redesign would take a substantial amount of time and cost to achieve.” Ex. 1002 ¶ 149. Dr. Pearce, however, does not explain sufficiently why combining mechanical expansion and inflation expansion would require a substantial amount of time and cost. See id.

“Factors that may be considered in determining level of ordinary skill in the art include: (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. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007) (quoting Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696 (Fed. Cir. 1983)). We are not persuaded that Dr. Pearce’s testimony concerning the level of skill in the art is erroneous to the extent it does not explicitly require experience related to devices used for uterine surgical procedures or surgical devices that employ expandable inflation-based and mechanical-based components. Patent Owner’s argument and Dr. Grundfest’s testimony is inconsistent with the ’989 patent, which does not disclose an ablation device or method of using an ablation device that solves problems unique to endometrial ablation or unique to surgical devices that employ expandable inflation-based and mechanical-based components. The ’989 patent does not limit the art to be “the field of minimally invasive surgical and uterine devices” (Ex. 2005 ¶ 60). The ’989 patent states: “The present invention relates generally to the field of apparatuses and methods for ablating or coagulating the interior surfaces of body organs. Specifically, it relates to an apparatus and method for ablating the interior linings of body organs such as the uterus and gallbladder.” Ex. 1001, 1:20–24; see also id. at 2:36–38 (“The present invention is an apparatus and method of ablation and/or coagulating tissue, such as that of the uterus or other organ”).” slip op. at 16

“that requires construction beyond what was done at the time of institution. Specifically, substitute claim 6 replaces the term “placing” with the new term “hanging.” We see no reason to interpret “hanging” apart from its plain and ordinary meaning. Thus, consistent with its dictionary definition, we construe “hanging” as “to fasten to some elevated point without support from below.” Merriam-Webster’s Collegiate Dictionary, 10th ed. (2000) (emphasis added). The substitute claims also use the transitional phrase “consisting essentially of,” which Shinn Fu argues should be construed presumptively as equivalent to “comprising.” Opp. 3–4 (citing Manual of Patent Examining Procedure § 2111.03). Tire Hanger argues for a narrower construction because, in its view, any additional steps would “materially change the basic and novel characteristics of the claimed method,” pointing to column 1, lines 26–59, of the ’897 patent. Reply 3 (citing Ex. 1002). We are not persuaded that a skilled artisan would view adding a simple extra step, such as raising the wheel to trip a safety latch while removing the wheel from the support arm (see, e.g., Ex. 1012, Fig. 2, 2:61–70), as materially changing the basic objective of the claimed invention in terms of being “easily accessible within the work space,” “remain[ing] out of the way,” and “not requir[ing] workers to bend over,” as made clear in the specification. Ex. 1002, 1:54–59. Thus, we determine that the phrase “consisting essentially of” should be construed as equivalent to “comprising,” so long as any additional unlisted steps “do not have a material effect on the basic and novel characteristics” of the claimed method.

- ScopeMotion to amend, grantedDecided for patent owner
“enlarge the scope of the claims of the patent or introduce new matter.” Shinn Fu argues that claim 9, which Tire Hanger proposes as a substitute for original claim 4, impermissibly enlarges claim scope by deleting the requirement that the individual “does not have to bend significantly at the waist to guide the wheel over the hanger.” That omission, in Shinn Fu’s view, makes claim 9 broader, not narrower, because it infers that an individual may indeed be bending over while handling the wheel on the support arm. Id. at 21–22. We disagree. Claim 9 depends from substitute claim 6, which recites that, when the vehicle is elevated, “the human can remove the wheel without bending over,” and when the wheel is on the support arm, the wheel can be removed “without the human bending over.” Thus, as a matter of dependency, claim 9 incorporates the limitations from claim 6 that entail handling the wheel on the support arm “without the human bending over.” That an amendment simply removes a limitation from a dependent claim and adds it 11 Shinn Fu also argues that the Motion to Amend should be denied because Tire Hanger failed to comply with its obligation of first “conferring with the Board” before filing the Motion, as required by 37 C.F.R. § 42.121(a). Opp. 2. We are not inclined to deny the Motion to Amend on this procedural ground. Before filing the Motion, Tire Hanger’s legal representative contacted the Board to seek clarification on whether a conference call was necessary and was advised it was not. Ex. 2008 ¶¶ 1–4. As such, we are satisfied that Tire Hanger fulfilled its obligation of conferring with the Board. to the claim from which it depends does not mean that the amendment has broadened the scope of the dependent claim from which the limitation has been removed.

“support for its use of the term “human” in the proposed substitute claims. Opp. 23. According to Shinn Fu, the specification only refers to a “worker” performing the steps of removing and replacing the vehicle’s wheel, not a “human.” Id. In Shinn Fu’s view, by using the term “human,” rather than “worker,” in the substitute claims, Tire Hanger has broadened the claims to include “such embodiments or species as newborns, toddlers, children, disabled people, and decrepit people,” for which the specification purportedly lacks written description support. Id. We construe claims based on a reasonable interpretation in light of the specification and prosecution history. Shinn Fu’s proposed construction is unreasonable. The specification of the ’897 patent speaks expressly in terms of “individuals in handling tire/wheel assemblies when mounting and removing them from vehicles.” Ex. 1002, 1:41–43 (emphasis added). Likewise, the original claims refer to “a person” and “an individual” in describing removal of the wheel from the vehicle. Id. at 8:24–30. Those disclosures provide clear support for use of the term “human” in the substitute claims. Thus, we are not persuaded that Tire Hanger’s proposed amendment of the claims lacks written description support.” slip op. at 18

“Komorita, on the other hand, presents a different picture because it clearly discloses what is called a “tire hanger” on an automotive lift. Ex. 1004, Abstract, Fig. 29. Even so, Tire Hanger asserts that the claimed method is patentable over Komorita because Komorita “merely teaches placing a wheel in a cradle” for holding the wheel from below, not “hanging the wheel on the support arm” or “guiding a hole in the wheel over the support arm,” as required by substitute claim 6. Mot. 13–14; Reply 9; Tr. 30–31. Thus, the question arises as to whether “hanging” a wheel on “a support arm,” per claim 6, is patentably distinct from supporting the wheel from below in a cradle, per Komorita. We conclude it is. To begin, we previously construed the term “hanging” to mean “to attach or place something so that it is held up without support from below.” See section III.A.2 above. Notwithstanding that Komorita is labeled as a “tire hanger,” it is clear from Komorita that the structure actually disclosed is not a hanger but a cradle that supports the wheel from below. Ex. 1004 ¶¶ 113, 114, Fig. 29. Thus, given our claim construction, Komorita does not appear to meet the “hanging” limitation of substitute claim 6. Moreover, the ’897 patent expressly distinguishes the claimed invention from cradle-like structures, such as that of Komorita. Notably, the ’897 patent describes various embodiments of hangers, each of which is “adapted to fit inside the rim of the tire/wheel assembly.” Ex. 1002, 6:17–21 (emphasis added). Figure 6 of the ’897 patent depicts one such embodiment with the hanger inside of the tire/wheel assembly. The ’897 patent goes on to state that “other structures may be used” to support a tire/wheel assembly, such as “an arcuate cradle” configured “to receive a tire therein . . . to rest the tire in the cradle.” Id. at 6:22–24 (emphases added). Further, another embodiment of a cradle is described that includes “a plurality of arms . . . adapted to receive and hold a tire therein,” and where the tire “rests in the cradle.” Id. at 6:35–37 (emphases added). A plain reading of the ’897 patent reveals that the hanger structures (id. at 6:15–21) are a separate embodiment from the cradle structures (id. at 6:22–42) because they are disclosed as “other structures” and because their modes of retaining the tire/wheel assembly are different. The hanger structure allows the tire/wheel assembly to hang thereon, and includes a specific structure adapted to fit inside a hole in the tire rim. Id. at 6:15–21. In contrast, the cradle structure receives a tire therein, and comprises a structure adapted to fit around and below the outside of the tire. Id. at 6:22–42. As such, we find that there is a structural distinction between hangers and cradles. Although the ’897 patent discloses both hangers and cradles, proposed” slip op. at 22
