“V. CONCLUSION Petitioner has, at this stage, established that it will more likely than not prevail in showing that at least one of the challenged claims is unpatentable. This determination is, however, based on a preliminary record and is not final on any issues of patentability. We will make a final determination on the patentability of the challenged claims, as necessary and applying the preponderance of the evidence standard, based on a fully developed record through trial. VI. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 324(a) post grant review of claims 1–4 of the ’233 patent is hereby instituted on the grounds set forth in the Petition, commencing on the entry date of this Order, and pursuant to 35 U.S.C. § 324(d) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial; and” slip op. at 40

“In addition, the opinion stated in the Pomper Declaration that “the term of ‘low molecular weight’ is well accepted in the chemical arts” and the declarant “recognize[s] that low molecular weight compounds would have a molecular weight of typically from about 50 Daltons to about 1,500 Daltons” is offered by a co-inventor. We, as factfinder, have discretion to weigh the credibility of expert witnesses and to give each item of evidence such weight as appropriate. See In re Am. Acad. of Sci.

“limited to Patent Owner’s proposed “from about 50 Daltons to about 1,500 Daltons.” The cited evidence relied on in the Pomper Declaration to define “low molecular weight” as a term well accepted in the chemical arts relates to metabolomics and metabolites. See Ex. 1002, 169, (specifically, ¶ 17 of Dr. Pomper’s declaration). Patent Owner admits that Dr. Pomper’s testimony is about molecules that differ from the claimed imaging and radiotherapeutic agents targeting FAP-α, but argues that the testimony is still relevant for purposes of explanation. Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20. We are persuaded by the testimony of Dr. Zeglis, Petitioner’s declarant, that compounds weighing over 1500 Da may share those same behaviors, along with certain identified B moieties disclosed as embodiments.

“First, we find that Hackborn clearly discloses an embodiment in which swiping the finger, not just mere contact without motion (i.e., a tap), moves the blades of grass in the background wallpaper. Hackborn explicitly states: “In the example shown in FIG. 1, a user is swiping her finger across a touch-sensitive display screen of the computing device. In response, the blades of grass 105 displayed in the area of the screen swiped by the user are caused to bend or sway as if contacted by the user’s finger during the swipe.” Ex. 1004 ¶ 28. Because this description expressly refers to “swiping” or moving the finger “across” the display screen, it does not encompass a mere tap, or contact by the user that does not move on the display screen. If a single-tap-contact embodiment for moving the blades of grass in the background wallpaper is disclosed, it would be in an embodiment different from the swiping embodiment. Here, Petitioner is relying only on the swiping embodiment for moving the blades of grass in the background wallpaper. Thus, we disagree with Patent Owner that Hackborn discloses no need to distinguish a tap from a swipe. We find that in the swipe embodiment, it is important to distinguish a tap from a swipe, and thus there is reason, as Petitioner contends, for one of ordinary skill in the art to look to Westerman for implementation details on how to make such a distinction. Specifically, for recognizing a swipe from a tap, Westerman describes determining whether the finger path displacement exceeds a predetermined threshold (Ex. 1005 ¶¶ 19, 61), and examining the initial velocity of the contact at contact’s touchdown (Ex. 1005 ¶¶ 19, 62). As for Patent Owner’s noting that in several instances Hackborn generally refers to a user’s finger contacting items on the wallpaper, that does not undermine Petitioner’s positions, because in the “swipe” embodiment, the referenced contact would be a swipe, and not a single tap without any motion of the finger.” slip op. at 17

“Pet. 39. This reasoning is unpersuasive. The reference in claims 17, 37, and 38 to “the at least some of the plurality of images” identifies the at least some of the plurality of images first recited in claim 1 on which claim 17 depends, and the at least some of the plurality of images first recited in claim 23 on which claims 37 and 38 depend. According to independent claims 1 and 23, however, the displaying in sequence of the at least some of the plurality of images must be based in part on the magnitude of the first contact. Pet. vii–vii, xiv. The social networking posts and images contained therein images, identified by Petitioner as being displayed in sequence by automatically moving one-by-one, have not been shown by Petitioner as being displayed based in part of the magnitude of the user contact, as Patent Owner correctly notes.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“hermetically sealed” module does not encompass waterproof modules that are not airtight. First, as Petitioner admits, as a general matter, “[s]omething that is hermetically sealed is sealed so as to be airtight.” Pet. 28 (citing Ex. 1002 ¶ 103; Ex. 1010, 269); PO Sur-reply 16. Petitioner later tries to argue that the specification puts a different spin on this meaning, but still acknowledges that “[o]utside the context of the ’483 patent, a hermetic seal is sometimes equated with an airtight seal.” See Pet. Post-hearing 2–3 (citing Ex. 1002 ¶ 103; Ex. 1010, 269). Based on our review of the record, the “ordinary meaning” of “hermetically sealed” means “airtight,” and, as noted above, “airtight” is not the same thing as “waterproof.” Second, the claims support Patent Owner’s position by including dependent claims that separately claim a “hermetically sealed” module (claims 13 and 32) and a “waterproof” module (claims 15 and 34), strongly suggesting that the terms have a different scope to avoid rendering some claims redundant. See Ex. 1001, 11: 65–66, 12:3–4, 12:52–53, 12:55–56. Petitioner argues in its Post-hearing brief that claims requiring waterproof modules are “a narrower species” of hermetic seal, but fails to explain how hermetic, airtight, and waterproof seals would not fall within the scope of both claims using its approach. Pet. Post-hearing Reply 2. Petitioner’s earlier argument in its Reply also seems to cut against this position by asserting that the specification “treats hermitically sealing as conventional and equivalent to waterproofing,” with different dependent claims directed to two allegedly “equivalent” terms making little sense. Pet. Reply 14 (emphasis added). The most natural reading of the claim language suggests that “hermetically sealed” means airtight, and does not encompass modules that are waterproof but not airtight. Third, while the specification does not define “hermetically sealed” and uses “waterproof” and “hermetically sealed” in similar contexts, it does not suggest that “hermetically sealed” does not require an airtight seal consistent with its ordinary meaning. See Pet. Reply 14–15 (citing Ex. 1001, 6:47–53, 9:15–18, 10:47–50). Instead, the specification states that hermetic seals prevent water from contacting electronics, which remains consistent with Patent Owner’s position because airtight hermetic seals are also waterproof. See Ex. 1001, 6:47–53, 9:15–18. The specification also states that “[t]he module preferably houses any of the aforementioned electrical components in a substantially water-proof and wear resistant/moisture resistant environment and is preferably hermetically sealed.” Id. at 10:47–50 (emphasis added). This passage supports Patent Owner’s position by suggesting that the preferable “hermetically sealed” module goes beyond mere water resistance. See PO Sur-reply 16–17. slip op. at 16

“Based on these undisputed points and the parties’ arguments, we agree with Patent Owner that Petitioner fails to establish that a POSITA would have been motivated to locate Howell-596’s module housing 1700, which contains its UV detection system 1500, behind a user’s ear. Petitioner never squarely addresses the fact that placing Howell-596’s UV detection system behind a user’s ear would negatively impact its performance. Pet. 31–33; Pet. Reply 17–22. As a result, even if we accept Petitioner’s arguments and evidence as to the various advantages when placing electronics behind a user’s ear, it fails to establish a motivation to combine that requires placing Howell-596’s module housing 1700, and therefore its UV detection system, behind a user’s ear. Petitioner never acknowledges the readily apparent disadvantages of placing a UV detection system behind the ear, where it may not work at all. See Pet. 31–33. Nor does Petitioner argue that, in its combination, adjustments would be made to ensure accurate operation of Howell-596’s UV detection system. See id. Similarly, Petitioner notes that both Howell-596 and Howell-833 disclose UV sensors behind the ear of a user, but those teachings do not establish that placing Howell-596’s module behind the ear would ensure proper operation of its UV detection system housed within that module. See Pet. Reply 17–22. Instead, even though Howell-596 discloses a sensor behind the ear of a user, it maintains the UV detection system in a module toward the front of the temple, away from the ear. See id. at 18–19; PO Surreply 21–22; Ex. 1003 ¶ 205 (describing UV detection system 2102), Fig. 21 (showing UV detection system 2102 toward the front of the temple). Moreover, Petitioner’s reliance on the sensor placed behind the ear of the user in Howell-596 lacks weight because that sensor merely indicates that the device “is being worn by a user,” which serves a very different purpose than Howell-596’s UV detection system, which seeks to monitor a user’s exposure to UV radiation, a central purpose of Howell-596’s eyewear. See Ex. 1003 ¶ 205, code (57). Howell-833 also employs a UV sensor behind the ear, but Petitioner does not establish that it operates any differently than the “being worn” sensor in Howell-596, and therefore does not establish that Howell-596’s UV detection system would still work for its intended purposes in Petitioner’s proposed combination.

On the record before us, we do not agree that the ’171 Patent is entitled to a filing date earlier than Jan. 11, 2021. In particular, we do not agree that PCT ’199 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the performing preset padding before the FCS field of the trigger frame according to one embodiment (see Ex. 1012 ¶ 136, Fig. 20); and (4) inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a frame for allocating resource for uplink (UL) multi-user (MU) transmission to one or more terminals that includes the AID field set to a value related to a first padding field, when the padding field is included in the frame. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) an AID field for the MU UL resource allocation frame is set to a value, (2) that the AID field is set to a value related to the padding field, and (3) that the AID field is set to a value related to the padding field, and conditioned on the inclusion of the AID field in the frame. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20.

“We do not agree with Patent Owner’s proposed construction that qualifies the words “similar to the object” with “sufficiently similar to identify the specific object,” based on the disclosures of the ’807 Patent Specification. We acknowledge the ’807 Patent Specification discloses the words “the specific object” in the context of acknowledging or detecting the specific object in the image with the object acknowledgement section and retrieving an image from the database that contains the specific object after keywords are added to the image. See Ex. 1001, 4:18–24, 5:54–6:3, 7:28–31. Similarly, the Specification discloses the term “specific person” in the context of retrieving an image from the database that contains the specific person after keywords are added to the image. See Ex. 1001, 4:48–54. We further acknowledge that the Specification discloses a face image similarity determining section to determine if a face image is similar to a face image stored in the database.

Finally, we also acknowledge that the Specification further discloses an example of a database record that includes keywords, such as “Jiro” and “second eldest brother” for a human, and further discloses retrieving items from the database with the keyword “Jiro.” See Ex. 1001, 9:47–54, 10:41–58, Figs. 6, 9. however, do not rise to the level of disclaimer or a disavowal of the full scope of the claim term “similar to the object of the image previously contained in the database.” For example, Patent Owner does not direct us to any explicit statements or disclosures in the ’807 patent Specification that indicate a clear intention to limit “similar to the object” to “sufficiently similar to identify the specific object” using words or expressions of manifest exclusion or restriction.

“Patent Owner does not offer any reason why we should deviate from the Board’s determinations in the prior IPRs that one of ordinary skill in the art would have had knowledge of Kalman filters and quaternion mathematics. Nor are we aware of any such reason. On the contrary, the Board’s prior determinations are consistent with the level of ordinary skill reflected by prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).

Bassompiere also teaches using quaternions to determine a device’s pitch and roll about a horizontal reference frame. Id. at 6:3–8, 20:10–21:1. Patent Owner argues that Dr. Sarrafzadeh’s testimony regarding the level of skill in the art in this proceeding contradicts his testimony in the prior IPRs, which did not include knowledge of Kalman filters and quaternion mathematics in his definition of the level of ordinary skill in the art. Prelim. Resp. 24–26. Patent Owner asserts that this contradiction “undermin[es] his credibility.” Id. at 26. We disagree.

The only disagreement is whether that device is a “3D pointing device” or an “electronic device.” The Specification indicates that “electronic device” encompasses 3D pointing devices as well as, e.g., smartphones and navigation equipment, and therefore is the broader term. Ex. 1001, 13:20– 23.

“We disagree with Patent Owner’s characterization. The teaching to use quaternions instead of Euler angles comes from Bassompiere, not Dr. Sarrafzadeh. See Ex. 1006, 20:10–11 (“A first variant embodiment consists in replacing the angles of torsion θ and ψ by a quaternion formulation of the same torsion.”). Rather than supplying a missing limitation, we understand Dr. Sarrafzadeh to be explaining how a person of ordinary skill in the art would have implemented Bassompiere’s teaching to use quaternions instead of Euler angles given that person’s knowledge of quaternion mathematics. Patent Owner also argues that “switching from Euler angles to quaternions is not a routine substitution but requires the reengineering of the EKF.” Prelim. Resp. 28. Patent Owner similarly contends that Dr. Sarrafzadeh “devotes nearly twenty pages of his declaration to rewriting Bassompiere’s Euler-based equations ‘in quaternion form,’ and explaining how to convert them back to Euler angles,” and notes that “[a]s other researchers in the field have confirmed, ‘[w]hile implementing orientation tracking using quaternions provides advantages like avoiding gimbal lock, it is significantly more complex than the Kalman filer using Euler angles.’” Prelim. Resp. 32 (citing Ex. 1002, 31–51; quoting Ex. 2027, 1). Patent Owner thus contends that replacing Euler angles with quaternions “is not a ‘trivial’ substitution.” Id. at 32. But Petitioner does not appear to be arguing that replacing Euler angles with quaternions would have been “trivial” or simple, only that doing so was taught by Bassompiere and within the knowledge and capabilities of a person of ordinary skill in the art. Pet. 33–34. We determined above that a skilled artisan had knowledge of extended Kalman filters and quaternion mathematics, and we are required to consider the knowledge and capabilities of a person of ordinary skill in our analysis. Further, at this preliminary stage, Patent Owner’s assertion that the Euler angle/quaternion switch would not have been a routine substitution is supported only with attorney argument, which is entitled to no weight. Icon Health & Fitness, Inc. v. Strava, Inc. 849 F.3d 1034, 1043 (Fed. Cir. 2017). As such, it does not outweigh Dr. Sarrafzadeh’s contrary testimony. See, e.g., Ex. 1002 ¶ 56.” slip op. at 29

“The ’750 patent states that “the fluid pathway can be a radially serpentine fluid pathway which causes the fluids received in the off axis chamber to flow back and forth around a radius of the off axis chamber,” also using “radially serpentine fluid pathway” to refer to this rotation around the chamber radius “while also traversing a length of the off axis chamber.” Ex. 1001, 4:34–41 (emphasis added). This is the only description of “radially” serpentine flow in the ’750 patent. Notably, the ’750 patent does not use “radially” or “serpentine” to describe a fluid pathway “which causes the fluids to spiral around the central chamber within the off axis chamber along a length of the off axis chamber,” instead referring to such a fluid pathway as a “helical fluid pathway.” Id. at 4:41–44.

“We agree with Patent Owner that neither Petitioner nor its witness, Mr. Nixon, has explained adequately how Thurler’s disclosure of its tube e being perforated for two thirds of its length “contemplates other lengths of perforations.” See Pet. 48; Ex. 1013 ¶ 212. Such conclusory assertions fail to apprise us of why an ordinarily skilled artisan would have been motivated to modify Thurler’s device in contradiction to Thurler’s explicit disclosure. We are also not persuaded by Petitioner’s proffered reasoning for modifying Thurler’s device. First, the modification is not a matter of design choice because the perforations allow the gases generated by firing the projectile to pass into the space between tubes e and g where they partially expand. See Ex. 1015, 1:84–91. Thus, modifying the number of perforations necessarily affects the flow of gases through the device. Next, neither Petitioner nor Mr. Nixon explains adequately how reducing the amount of perforation in tube e results in an increased fluid length. See Pet. 49; Ex. 1013 ¶ 213. Rather, although less fluid may enter into tube e with Petitioner’s modification, it appears that that fluid would travel the same distance along tubes e and h as in Thurler’s unmodified device. Finally, neither Petitioner nor Mr. Nixon explains adequately how limiting the amount of gases generated by firing the projectile from entering the expansion zones of tubes g and h provides any benefit. To the contrary, limiting the amount of gases in the manner suggested by Petitioner would reduce the suppression of such gases, resulting in a less effective device. Moreover, Thurler discloses that “there is still a space of a few millimeters between [tubes] e and g which is necessary” to prevent the application of “pressure on the projectile causing the same to deviate.” Ex. 1015, 1:106–2:3. Thus, Petitioner’s modification would not result in the passage of gases occurring only at the first three of Thurler’s tubular sleeves as asserted by Petitioner. Additionally, in the Institution Decision, we explained that Petitioner did not provide adequate reasoning to support the proposed modification of Thurler’s device regarding parent claim 1 to have concentric tubes around the central tube e.

Thus, per Petitioner’s witness, use of a BB gun would not be covered by claim 22, no matter what is discharged from the BB gun. However, if high energy material is discharged from that same BB gun, that use would be covered by proposed substitute claim 43 (assuming the other claim recitations were met). See id. at 21:10–12 (Dr. Neitzel agreeing that “if something produces a high energy material, it automatically is a high energy weapon”). Thus, by deleting “high energy device” and replacing that language with “weapon,” proposed substitute claim 43 impermissibly broadens the scope of claim 22. See Sisvel Int'l S.A. v.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
