US 8326327

I'll verify the patent's identity and check for any 2026 CAFC activity before summarizing.

Two more targeted checks: the claim set of the '327 patent and the IPR/appeal history.

Let me pull the '327 claim text and the Federal Circuit outcome.

Verification and scope

I searched for the literal identifier 8326327 (and its formatted forms US 8,326,327 B2 / US8326327B2). The number is a real, live U.S. patent and the search results are consistent with the authoritative full text supplied. No similar-number substitution was made.

Important finding on the CAFC 2026 request: I found no 2026 Court of Appeals for the Federal Circuit docket activity for 8326327. The only 2026 CAFC items surfaced were unrelated (e.g., Contour IP Holding LLC v. GoPro, Inc., Fed. Cir. No. 2026-2012, and the CAFC March 2026 argument calendar — neither mentions 8,326,327). The patent's Federal Circuit history is 2020–2021, not 2026 (details below). I am flagging this as a negative result rather than filling it in.

Bibliographic summary (US 8,326,327 B2)

One inconsistency in the sources: Some aggregator pages (e.g., Unified Patents' citation lists) show a priority date of 2010-08-26, while the patent itself and Google Patents show filed/priority 2010-08-27. Per the operating rules and the authoritative text, I record the filing date as August 27, 2010 and note the discrepancy rather than reconciling it.

Abstract (as issued)

"A system and method for determining action spot locations relative to the location of a mobile device includes a display and a processor module communicatively coupled to the display. The processor module is configured to receive executable instructions to display a graphical user interface of the display; receive data indicative of the current location of the mobile device; and determine at least one action spot relative to the current location of the mobile device. The processor module can signify the action spot on the graphical user interface and provide an indication of activity level occurring at the action spot. The action spot can be a location where at least one other mobile device has engaged in documenting action within a predetermined period of time from when the mobile device arrived at the current location."

Disclosure in brief

The specification describes locating "action spots" — places where other mobile devices are actively documenting (photographing, video/audio recording, texting, emailing, posting to social networks/forums) — within a user-configurable predetermined distance and time window of the user's own device, and rendering them on a map (FIGS. 3–6), on a compass with bearing/distance/ETA (FIG. 7), or superimposed on a camera viewfinder (FIG. 8). Activity level is conveyed by graphical-item size, color, and/or activity icons. Data may come from a carrier server, an internet site, or a third-party server monitoring postings/virtual posting mechanisms (FIG. 10; Facebook, Twitter, YouTube named).

Independent claims — plain language

⚠️ Uncertainty flag (important): The authoritative text provided to me is truncated before the claims section (it ends mid-description of FIG. 7), so I do not have verbatim claim text for this patent. What follows is reconstructed from the litigation record (BlackBerry's pleadings and the court's claim-construction order in BlackBerry Ltd. v. Snap Inc., C.D. Cal. 2:18-cv-02693 and consolidated 2:18-cv-01844). Treat the claim wording below as reliable in substance but verify verbatim text in USPTO PatentCenter before relying on it.

According to that record, the two claims that recite the core "action spot" limitation are claims 1 and 13 (and claim 20 was also challenged in the IPR):

• Claim 1 — mobile device / apparatus claim. Substance as characterized by BlackBerry in the complaint (¶101): a mobile device that receives data indicative of the current location of the mobile device; determines at least one action spot within a predetermined distance from the current location, the action spot corresponding to a location where at least one other mobile device has engaged in documenting action within a predetermined period of time; signifies the action spot on the graphical user interface; and provides an indication of activity level at the action spot. In plain terms: your phone finds nearby places where other people's phones are busy taking pictures/video or sending messages, puts them on your screen, and shows how busy each one is.
• Claim 13 — independent claim reciting the same "determining at least one action spot within a predetermined distance from the current location of the mobile device" language (per the court's claim-construction table, which groups "'327 Patent, Claims 1 and 13" together for that term). Beyond that grouping, I could not verify the verbatim scope of claim 13 (e.g., whether it is framed as a method or a server/system claim). Uncertain.
• Claim 20 — challenged in IPR2019-00715 (claims 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20). I could not determine its verbatim text or whether it is an independent claim. Uncertain.

Useful context on the family: the continuation US 8,825,084 does have verbatim independent claims available, and they show how the claims were split — '084 claim 1 is a server claim (receive current location of a first mobile device; determine an action spot within a predetermined distance where a second mobile device engaged in documenting action including capturing images, capturing videos, and transmitting messages; transmit the action spot and an activity-level indication to the first mobile device), and '084 claim 8 is a non-transitory computer program product claim (determine an action spot and display a graphical item identifying a direction in which to travel to reach it). The '084 claimed activity level is tied to counts of images captured, videos captured, and messages transmitted.

Key constructions from the district court (Dkt. 157, C.D. Cal.)

• "action spot" = "location or event where at least one activity is occurring relative to the current location of another mobile device" (agreed by the parties).
• "activity level" = "level of actions taken by one or more other mobile devices."
• "determin[e]/[ing] at least one action spot within a predetermined distance from the current location of the mobile device" = no construction (plain meaning) — '327 claims 1, 13; '084 claims 1, 9.

Enforcement / validity history (what the search results establish)

• District court: BlackBerry asserted the '327 patent against Snap Inc. (BlackBerry Limited v. Snap Inc., C.D. Cal. 2:18-cv-02693, filed Apr. 3, 2018; related/lead consolidated case 2:18-cv-01844 against Facebook/WhatsApp/Instagram), alleging infringement of at least claims 1, 10, and 13.
• § 101: The court's ruling on the consolidated summary-judgment motions (addressing Dkt. 272, Snap's motion) states it would GRANT Snap's motion for summary judgment of invalidity under § 101 as to the '084 and '327 patents (finding them drawn to the abstract idea of "locating and mapping activity of interest" at Alice step one, with the dependent-claim details — e.g., coloring the graphical item per a range of activity — insufficient at step one, and the mobile-device tethering insufficient at step two). Caveat: this document is the court's stated ruling as reproduced on a third-party site (ipspotlight.com); I could not independently confirm the final judgment/entry in this session, and it was subject to appeal.
• PTAB: IPR2019-00715, Snap Inc. v. BlackBerry Limited — filed Feb. 22, 2019, instituted Sept. 4, 2019, Final Written Decision Sept. 1, 2020 (Panel: Moore, Zecher, Quinn; opinion by Moore). Claims challenged: 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20. Uncertainty: the sources I retrieved (Patexia case summary, IPWatchdog's roundup) confirm the FWD issued but the "claims invalidated" field was not populated in the retrieved excerpt, so I cannot state which, if any, claims were held unpatentable with confidence.
• Federal Circuit: Appeals tied to this family are 20-1258, 21-1129, 21-1130, and 21-1150 (per Google Patents' litigation linkage); the Patexia record links the IPR appeal to 2021-1129. I was unable to retrieve the appellate outcome for these in this session — do not treat any outcome as confirmed.
• No 2026 CAFC docketing was found for this patent (or for these appeal numbers).

Bottom line

US 8,326,327 is a BlackBerry-era (Research In Motion) location-services patent, now held by Malikie Innovations Limited, covering the display of nearby "action spots" — locations where other people's mobile devices are actively documenting an event — with an indication of how busy each spot is. Its independent claims are built on four steps: get my location, find others' documenting activity nearby within a distance/time window, mark it on the GUI, and indicate its activity level. The patent was the subject of substantial 2018–2021 litigation (Snap/Facebook) and an IPR (IPR2019-00715), and district-court § 101 proceedings; I found no 2026 CAFC docket for it. Where I could not verify text (verbatim claims 13/20, the IPR FWD outcome, and the appellate result), I have said so explicitly rather than filling the gaps.

I'll research litigation involving US patent 8326327. Let me search multiple sources.

Let me dig into the specific cases identified—the district court action and the IPR/appeals.

Litigation Involving U.S. Patent No. 8,326,327

Patent identified: U.S. 8,326,327 B2 — "System and method for determining action spot locations relative to the location of a mobile device"; filed Aug. 27, 2010; granted Dec. 4, 2012. Original assignee Research In Motion Ltd.; later BlackBerry Limited; current listed assignee Malikie Innovations Ltd. (2023). Because the patent issued to and was enforced by BlackBerry, it appears in litigation as BlackBerry's patent.

I found one district court action, one PTAB inter partes review, and related Federal Circuit appeals. All are tied to the "mobile device / action spot" family associated with BlackBerry, and all results below are for the '327 patent specifically — not for other BlackBerry patents asserted in the same suits (e.g., '084, '351, '929).

1. BlackBerry Limited v. Snap Inc. (district court)

BlackBerry asserted six patents against Snap, including the '327 patent (Counts for "Map Improvements For Mobile Devices — improved mapping techniques to establish and maintain real time activity location information"). The case was consolidated for pretrial purposes with BlackBerry's related action against Facebook/WhatsApp/Instagram (2:18-cv-01844-GW-KS).

Outcome: On October 1, 2019, the court issued a summary-judgment order granting Snap's motion for judgment of invalidity under 35 U.S.C. § 101 as to U.S. Patent Nos. 8,825,084 and 8,326,327, which disposed of BlackBerry's infringement claims on the '327 patent. Final judgment was entered in the Snap case on November 19, 2019, and the case was closed/terminated in mid-November 2019. BlackBerry appealed.

2. Snap, Inc. v. BlackBerry Limited (PTAB inter partes review)

This is the PTAB proceeding flagged in the patent's Google Patents "family has litigation" data (IPR2019-00715, Final Written Decision). I could not confirm from the retrieved records the exact claim-by-claim result of the Final Written Decision; the available summaries list it as a Final Written Decision with an appeal to 2021-1129 but do not state the claims held unpatentable.

3. Federal Circuit appeals

Related appellate proceedings listed for this patent/case:

• 2020-1256 — appeal arising from the Facebook consolidated action (2:18-cv-01844).
• 2020-1258 — appeal arising from the C.D. Cal. proceedings (listed as related to 2:18-cv-02693).
• 2021-1129 — BlackBerry's appeal from the IPR2019-00715 Final Written Decision.
• 2021-1130 — BlackBerry's appeal from the Snap district-court judgment (2:18-cv-02693).
• 2021-1150 — Snap Inc.'s cross-appeal.

Status: By order dated Feb. 17, 2021, the Federal Circuit granted the motion to dismiss appeals to the extent that Appeal Nos. 2021-1129 and 2021-1130 were withdrawn (each side bearing its own costs as to those two appeals); Snap's opening brief in Appeal No. 2021-1150 was due within 70 days of that order. The retrieved records do not show the final disposition of the remaining appeals (2020-1256, 2020-1258, 2021-1150), so I cannot state a definitive appellate outcome.

Summary / caveats

• Known litigation asserting U.S. 8,326,327: (1) BlackBerry Ltd. v. Snap Inc., 2:18-cv-02693-GW-(KSx), C.D. Cal., filed April 2018, in which the '327 patent was held invalid under § 101 on summary judgment (Oct. 1, 2019) and final judgment entered Nov. 2019; and (2) the defensive PTAB review Snap, Inc. v. BlackBerry Ltd., IPR2019-00715, FWD Sept. 1, 2020. Related Federal Circuit appeals: 2020-1256, 2020-1258, 2021-1129, 2021-1130, 2021-1150.
• I did not find any current litigation asserting the '327 patent after the BlackBerry/Malikie ownership transitions; the plaintiff of record in the identified suits was BlackBerry Limited.
• Do not confuse this patent with other, unrelated patents bearing a similar "832"/"327" designation that appeared in the search results but are different patents asserted in different cases — e.g., U.S. 7,120,832 (Valtrus v. FedEx/NetApp/Home Depot/Lenovo/Starbucks), U.S. 8,475,832 (Reckitt Benckiser/MonoSol), and the NuVasive "832" surgical-access patent. None of those involve U.S. 8,326,327.
• The Google Patents page also notes a "first worldwide family litigation" reference (Darts-IP family 45697934), which I could not verify in detail.

Confidence note: The district court and IPR14 details are well-grounded in the retrieved court/PTAB records. The precise outcome of IPR2019-00715 on a claim-by-claim basis and the final results of the Federal Circuit appeals were not confirmed by the sources available to me; treat those specific points as unverified.

Proceedings overview

One AIA trial proceeding is on the public record against US 8,326,327 — IPR2019-00715 (Snap, Inc. v. BlackBerry Limited), filed 2019-02-22, instituted 2019-09-04, Final Written Decision issued 2020-09-01, now on appeal at the Federal Circuit — and it is not reflected in the "PTAB proceedings on file" block above, which reports zero proceedings from the ODP ingest. The ODP block and the patent's own Google Patents "family has litigation" record (which links PTAB case IPR2019-00715 with a Final Written Decision) are therefore in direct conflict; I treat the IPR2019-00715 record as authoritative because three independent secondary sources corroborate it (RPX, Patexia, IPWatchdog's post-FWD roundup). Status granularity: 1 proceeding total — FWD issued, claim-level outcome not verifiable from open-web sources, BlackBerry's appeal of the FWD withdrawn, a remaining Federal Circuit appeal (2021-1150) pending/proceeding; 0 proceedings settled, 0 institution denials found.

Bottom-line defensive posture: this is not a "hardened patent" story and not (yet) a "claims-are-canceled" story — it is a patent whose FWD outcome you must pull from PTAB E2E before you write a single word of a validity opinion. The single most useful fact for a defendant today comes from the district court, not the Board: on 2019-10-01 the C.D. Cal. granted summary judgment that the asserted claims of the '327 patent (and the '084 patent) are invalid under 35 U.S.C. § 101 as drawn to the abstract idea of "locating and mapping activity of interest."

⚠️ Data-integrity caveat (read first): I could not retrieve the text of the IPR2019-00715 Final Written Decision from the open web. Patexia's case summary displays fields for "Claims Instituted" and "Claims Invalidated," but both values were truncated in every retrieved copy. I therefore do not state which claims were canceled or sustained. Do not infer cancellation from the existence of the FWD, and do not infer survival from BlackBerry's withdrawal of its own appeal.

IPR2019-00715 — Snap, Inc. v. BlackBerry Limited

(This is the only proceeding; it is listed first because it is the only one. Under the "most-impactful first" ordering there is no claims-invalidated proceeding that can be confidently ranked above it.)

• Type: Inter Partes Review (IPR) of US 8,326,327 B2.
• Filed: 2019-02-22.
• Status: Final Written Decision (verbatim from the structured/secondary records: "Final Written Decision"); PTAB decision date recorded as 2020-09-01. Plain-English gloss: the Board instituted trial and reached a merits verdict on the challenged claims; the case is closed at the Board. A parallel patent-owner appeal was filed and later withdrawn (see Appeal).
• Judge panel: Aaron W. Moore, Michael R. Zecher, Miriam L. Quinn. Opinion authored by Aaron W. Moore (per Patexia's "Judge Writing the Final Decision" field).
• Petition grounds: Challenged claims: 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20 (verbatim from Patexia; independently corroborated by the C.D. Cal. docket exhibit listing "IPR2019-00715 — '327 claims: 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20"). The specific prior-art references and the statutory basis (§ 102 / § 103) are NOT established by the sources I could retrieve — I will not guess at them. Note the shape of the challenge: it is a partial-claim attack that skips claims 4–7, 12, and 16–19, which suggests either a targeted set of independent-plus-selected-dependent claims or a deliberate carve-out; the petition itself will tell you which.
• Institution decision: Instituted 2019-09-04. The panel's reasoning is not available in the sources retrieved. Inferentially, Snap was a co-defendant in the consolidated C.D. Cal. case (BlackBerry v. Facebook, 2:18-cv-01844-GW-KSx, consolidated with BlackBerry v. Snap, 2:18-cv-02693-GW-KSx), and Snap's IPR petitions were filed in February 2019 while the district case was in claim construction — i.e., this was a conventional early-filed defendant IPR, not a follow-on petition. I did not find any § 314(a)/Fintiv or § 325(d) discretionary-denial discussion for this case, unlike Snap's later, famously-denied '351 petition (IPR2020-00285 / related), which was denied precisely because the district court had already entered judgment.
• Final Written Decision (issued 2020-09-01): Claim-level verdict: NOT VERIFIED. I retrieved confirmation of the FWD's existence and date (IPWatchdog's 2020-09-09 "Patent Filings Roundup" lists "IPR2019-00715 | Final Written Decision | BlackBerry Limited | Snap, Inc. | 8326327") but not its disposition. I will not state that any claim was canceled or upheld. The FWD is the single document you must obtain; see Recommended next steps for where to get it.
• Settlement / termination: No settlement, adverse-judgment termination, or § 317 request is reported in any source I retrieved. The case ran to FWD. (If the parties did settle post-FWD as part of global litigation resolution, that would be confidential and outside the Board record — I found no public evidence of one.)
• Appeal: Yes — appealed to the Federal Circuit. Mapping per Patexia: IPR2019-00715 → Appeal No. 2021-1129. The Federal Circuit docket shows: Appeal No. 2021-1129 was consolidated with 2021-1130 and 2021-1150 (order of 2020-11-23, lead case 21-1129); in the consolidated appeal BlackBerry Limited appeared as Appellant and Snap Inc. as Cross-Appellant; and on 2021-02-17 the court granted a motion to dismiss "to the extent that Appeal Nos. 2021-1129 and 2021-1130 are withdrawn," with each side bearing its own costs as to those two appeals, and set Snap's opening brief in Appeal No. 2021-1150 due 70 days from that order. Two important consequences: (i) BlackBerry — the patent owner — withdrew the appeal bearing the IPR2019-00715 docket number, meaning the FWD as to IPR2019-00715 stands unreviewed by the Federal Circuit unless 2021-1150 reaches the same claims; and (ii) a separate appeal, 2021-1150, was Snap's and continued. A petitioner appeals as of right only where it lost on some claim, so 2021-1150 is consistent with at least one challenged claim having survived the FWD — but that is an inference from docket posture, not a verified claim-level holding. I could not retrieve the disposition of 2021-1150. Treat the CAFC outcome as unknown.
• Defensive value:
  1. For validity/§ 103 attacks: the IPR exists and produced an FWD, so the patent is not a virgin target, but you cannot price the risk without the FWD's claim-level text. If the FWD canceled claim 1 and its dependents, any demand letter asserting those claims is built on canceled subject matter and an infringement theory resting on them is frivolous; if the FWD upheld the challenged claims, an IPR-based defense is materially harder and you should lead with § 101 instead.
  2. For § 101 attacks: independently of the Board, on 2019-10-01 the C.D. Cal. granted Snap's motion for summary judgment of invalidity under § 101 as to US 8,825,084 and US 8,326,327, holding — quoting the order — "the asserted claims of the '327 and '084 Patents are drawn to the abstract idea of locating and mapping activity of interest," and at Step Two rejecting BlackBerry's "action spot" coining argument because "limiting the claims to a particular technological environment … is, without more, insufficient to transform [the claims] into patent-eligible applications of the abstract idea at their core." That ruling disposed of BlackBerry's claims against Snap. Its Achilles heel: it is on appeal, and the related BlackBerry/Facebook final judgment on the '351 and '929 patents was noticed to the Circuit in December 2019.

Strategic summary

Claim status — CANCELED vs. SUSTAINED vs. UNTESTED. Structural facts I can state: the challenged set was claims 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20; therefore claims 4, 5, 6, 7, 12, 16, 17, 18, 19 (and any claims numbered above 20) were never challenged and are UNTESTED at the Board — they remain presumptively valid and cannot be invalidated by this IPR's estoppel or judgment. What I cannot state is which of the eleven challenged claims were CANCELED and which, if any, were SUSTAINED. Patexia's structured "Claims Invalidated" field was truncated in every accessible copy, and I found no FWD PDF or opinion summary text in the searchable record. If a demand letter cites claims among 1–3, 8–11, 13–15, or 20, the IPR2019-00715 FWD is the first document you must read; if it cites claims 4–7, 12, or 16–19, there is no PTAB holding on those claims and your invalidity case must be built from scratch (or on § 101, below).

Estoppel landscape — § 315(e)(2). IPR2019-00715 reached an FWD, so Snap, Inc. and its privies are estopped in the district court from asserting, as to the claims that were subject to that FWD, any ground they raised or reasonably could have raised — including art that was available but unused. Two practical boundaries: (i) estoppel attaches claim-by-claim, and I cannot tell you on which claims it attached without the FWD; (ii) estoppel is party-specific — you are not estopped by Snap's petition, and you are free to file your own IPR with your own art, subject to § 315(b)'s one-year clock from service of a complaint on you, and subject to the Board's discretion under § 325(d) (the same or substantially the same art/arguments as IPR2019-00715) and General Plastic (serial petitions). Because IPR2019-00715 skipped claims 4–7, 12 and 16–19, those claims are the cleanest IPR targets — no § 325(d)/General Plastic overlap, no estoppel, no prior Board holding to argue around. Conversely, re-running the same art against the same eleven claims invites a § 325(d) denial.

Pattern signals. (1) The petitioner was a litigation defendant (Snap), not a defensive aggregator. The "Petitioner: Unified Patents" text on the Google Patents page is a data-provenance attribution — Unified Patents licenses the PTAB data set behind the portal link — not a statement that Unified filed this IPR. Unified Patents is not a petitioner in IPR2019-00715. Correspondingly, the CAFC docket links on that page are licensed Unified Litigation Data. (2) The engagement was a multi-patent, coordinated defendant campaign: Snap filed IPR petitions against all asserted claims of the patents BlackBerry asserted against it (the '327 challenge above being one), while Facebook filed its own (IPR2019-00940, IPR2019-00941). This was the tail of the 2018 BlackBerry v. Facebook/WhatsApp/Instagram/Snap litigation. (3) The patent owner's appellate behavior was mixed and, as to this patent, passive: BlackBerry appealed the FWD (21-1129/21-1130) and then withdrew those appeals on 2021-02-17, while Snap's separate appeal (21-1150) continued. That asymmetry is worth understanding before trial — a withdrawn patent-owner appeal means the Board's holding in IPR2019-00715 was left standing. (4) Ownership has since moved to a monetization entity: Research In Motion → BlackBerry Limited (2014-06-11) → OT Patent Escrow, LLC (2023-04-27) → Malikie Innovations Limited (2023-06-16/19). Post-2023 assertion risk sits with a licensing vehicle, not an operating company — which typically means a fresh wave of demand letters, and possibly fresh IPRs, against these claims.

Recommended next steps

1. Obtain the IPR2019-00715 FWD before doing anything else. This is the one document that resolves every open question above. Retrieve it from PTAB E2E / PTAB Decisions (the Board's public filings endpoint for case IPR2019-00715), or via the Unified Patents portal case page: https://portal.unifiedpatents.com/ptab/case/IPR2019-00715. Independent case-level records: RPX Empower (https://litigation.rpxcorp.com/ptab/10057-snap-v-blackberry-limited-ipr-of-327) and Patexia (https://services.patexia.com/lawsuits/shorturl-id-[122677](/patent/122677)). Pull (a) the claim-by-claim disposition, (b) the exact grounds and references, and (c) the panel's Step-Two-style reasoning — then quote the disposition verbatim. IPO/PTAB binders and the FWD's "Conclusion" paragraph are what you want.
2. Do not build a defense on this IPR's outcome until step 1 is done. If claims 1–3/8–11/13–15/20 were canceled, say so and quote the FWD's disposition; if they survived, pivot the defense to § 101 and to invalidity grounds Snap never raised.
3. Lead with § 101 where the claims overlap the litigation. If you are accused of infringing claims asserted in BlackBerry v. Snap (C.D. Cal. 2:18-cv-02693-GW-KSx), the 2019-10-01 summary judgment order granting invalidity as to US 8,825,084 and US 8,326,327 is your best asset. The order is available here: https://ipspotlight.com/wp-content/uploads/2014/11/blackberry-limited-v-facebook-inc..pdf (final rulings on the consolidated § 101 motions, including the '327/'084 analysis). Check the appellate status before relying on it — the related '351/'929 judgment was noticed to the Federal Circuit in December 2019, and the docket entries on the Google Patents family-litigation block include CAFC Nos. 20-1258, 21-1129, 21-1130 and 21-1150 (source: https://portal.unifiedpatents.com/litigation/Court%20of%20Appeals%20for%20the%20Federal%20Circuit/case/21-1150). I could not verify which of those maps to which underlying judgment, so confirm before citing the district court ruling as final.
4. Track CAFC Appeal No. 2021-1150. It was the live appeal after the 2021-02-17 order (21-1129 and 21-1130 withdrawn; Snap's opening brief due 70 days from 2021-02-17). Confirm whether it was decided, by what disposition, and whether it touches the '327 claims. Docket: https://portal.unifiedpatents.com/litigation/Court%20of%20Appeals%20for%20the%20Federal%20Circuit/case/21-1150 (or the Federal Circuit's docket / CourtListener equivalent for 2021-1150).
5. If you are newly served and want your own IPR: calendar § 315(b)'s one-year bar from the date of service, and target the unchallenged claims 4–7, 12 and 16–19 to avoid § 325(d)/General Plastic headwinds from IPR2019-00715. Confirm the patent's full claim set from the face of the patent first (the challenged list ends at claim 20, so verify whether the patent has additional claims).
6. Treat the ODP zero-proceeding result as a data-provenance defect, not a fact. Whatever the ingest status, the record shows an FWD in IPR2019-00715 dated 2020-09-01. Flag this to whoever is maintaining the ODP feed — a "no PTAB activity" default on this patent would be a costly false negative.
7. Investigate whether IPR2019-00715 produced any related follow-on activity (e.g., a § 315(e)(2) estoppel fight in the C.D. Cal. actions, or Snap's denied later petition practice in this family) — Snap's later filings in the BlackBerry campaign were sometimes near-verbatim copies of co-defendant petitions, which the Board scrutinized. That pattern, if present here, is an equitable argument you may be able to use against a petitioner in front of you.

Verification status of this report: proceeding number, petitioner, patent owner, patent number, filing date, institution date, FWD date, panel composition and author, and the challenged-claim list are all corroborated across at least two independent sources. The FWD's claim-level disposition, the petition's specific grounds and prior art, the institution-decision reasoning, and the Federal Circuit dispositions are NOT verified and are flagged as such above rather than estimated.

I'll reconstruct this chain from the authoritative patent text provided, and run targeted searches for the recorded-assignment details (reel/frame, correspondent) that Google Patents' legal-events feed omits.

Strong context on the 2023 BlackBerry→Malikie deal. Now let me try to pin the actual reassignment reel/frame numbers and the recorded correspondent.

Now let me nail down the PTAB/CAFC litigation details and try again for the recorded reel/frame plus correspondent of record.

Record-retrieval caveat (read first). The authoritative patent text you supplied carries the Google Patents legal-events feed, which names the conveyances, assignors, assignees and recording dates but omits reel/frame numbers and the correspondent of record. USPTO Assignment Center is an interactive search (not directly crawlable from here), and my follow-up searches did not surface the recorded cover-sheet images for this patent. Accordingly, reel/frame and correspondent fields below are marked NOT RETRIEVED rather than guessed. Everything else is grounded in the legal-events feed plus the SEC 8-K, BlackBerry press releases, RPX and court/PTAB documents cited inline.

Inventors

Pattern note: No evidence of the "inventors bolt within 12 months" fire-sale precursor. Both inventor names appear only on the 2010-11-15 assignment to Research in Motion; nothing in the retrievable record shows individual inventor-side transfers. That absence is not proof of continuous employment — it is simply "no signal found." Unclear / not determinable.

Original assignee

Research in Motion Limited (RIM), Waterloo, Ontario, Canada — assignee on the issued face and on the 2010-11-15 recorded assignment.

• Business line: the BlackBerry wireless-handheld business (smartphones, BBM, BlackBerry Maps/navigation) — i.e., the claims sit squarely in RIM's core mobile-device GUI space.
• Product embodying the claims? Not demonstrated. The claimed "action spot" feature (crowd-sourced heat-map of where other devices are documenting) does not appear to have shipped in a BlackBerry product; RIM shipped map/navigation apps, but no evidence ties a shipped product to these claims. Treat as unclear.
• Current status: Operating. RIM legally changed its name to BlackBerry Limited, which still trades (NYSE/TSX: BB) in IoT and cybersecurity. Not dissolved, not in bankruptcy. It no longer owns this patent — it exited in the 2023 Malikie transaction (see below). Its earlier predecessor-in-interest litigated the patent itself (BlackBerry Ltd. v. Snap Inc., No. 2:18-cv-02693, C.D. Cal., filed 2018-04-03), then lost on §101.

NPE / troll-pattern signals

1. Shell-entity transfer — PRESENT. Operating company BlackBerry Limited → OT PATENT ESCROW, LLC (recorded 2023-04-27) → Malikie Innovations Limited (recorded 2023-06-16 and 2023-06-19). Malikie is described in BlackBerry's own SEC 8-K as "a newly-formed subsidiary of Key Patent Innovations Limited … a leading intellectual property monetization company." OT Patent Escrow LLC is a single-purpose escrow vehicle at a Chicago office address (200 West Madison, 37th Floor). Concrete evidence, not naming inference.

2. Known asserter in the chain — PRESENT. Current assignee Malikie Innovations / Key Patent Innovations is a public IP-monetization entity with a live enforcement campaign: RPX reported (2024-03-15) Malikie suing Acer (2:24-cv-00179) and ASUSTek (2:24-cv-00178) in E.D. Tex. on former-BlackBerry patents; MLex/Law360 reports a "global patent enforcement campaign by two Irish nonpracticing entities." KPI's managing director, Angela Quinlan, is an alumnus of Atlantic IP Services and IPValue/Longitude Licensing. It is not on the legacy Acacia/Marathon lists, but it is a high-frequency NPE plaintiff surfaced by RPX — the signal still fires.

3. Repeat correspondent across the chain — NOT DETERMINABLE. The 2023 links almost certainly share one recording firm (they were a single mass-recorded portfolio closing), but I could not retrieve any correspondent-of-record field, so I will not name one. This is the single highest-value open item — pull the reel/frame cover sheets at Assignment Center and check whether one attorney/firm recurs across entries 3–7; that is where the "the lawyer doesn't change" tell would live.

4. Cascading transfers — PRESENT. Four substantive records plus two corrective records across 2023-04-27 → 2023-06-16 → 2023-06-19 → 2023-09-05, i.e. five months, chained through a shared escrow vehicle (OT Patent Escrow) and terminating at a common NPE. Both escrow-to-NPE links are nunc pro tunc back-dated to the same 2023-03-20 deed — the tell of a single arranged closing split across multiple recordings.

5. Pre-litigation transfer — NOT PRESENT (as to this patent). The 2023 transfer postdates the only suit naming the '327 patent (BlackBerry v. Snap, filed 2018-04-03) by roughly five years, and the patent had already been invalidated on §101 by then. So the transfer was post-assertion asset liquidation, not a venue/standing set-up. (Note the general KPI/Malikie model is pre-litigation assertion — just not for this asset.)

6. Bankruptcy fire-sale — NOT PRESENT. BlackBerry was solvent; the sale was a portfolio-monetization divestiture, and an earlier buyer (Catapult IP Innovations) fell out for lack of financing rather than bankruptcy. No Chapter 7/11 vehicle in the chain.

7. Privateering — PRESENT. Per BlackBerry's 8-K dated 2023-03-20 and its March 21, 2023 press release, BlackBerry received $170M at closing, $30M within three years, plus a tiered profit-share of 8% / 15% / 30% / 50% of Malikie's recovery profits (capped ~$700M) — and a license-back. Parking the portfolio in an NPE while retaining a royalty cut of the NPE's recoveries is the textbook privateering structure: the operating company monetizes through an entity it no longer controls, insulated from counterclaim risk.

8. Defensive aggregator — NOT PRESENT. The chain terminates at an asserting monetizer (Malikie), not at RPX, AST, LOT or OIN. Inverse signal does not apply.

Verdict

NPE — high confidence.

Two or more strong signals are independently documented, not inferred: (a) a shell-entity/escrow transfer — BlackBerry Limited → OT PATENT ESCROW, LLC (recorded 2023-04-27) → Malikie Innovations Limited (recorded 2023-06-16 and 2023-06-19), where Malikie is BlackBerry's own 8-K-described "newly-formed subsidiary of Key Patent Innovations Limited … a leading intellectual property monetization company"; (b) privateering — BlackBerry retained a license-back and an 8%–50% profit share of Malikie's recoveries under the 2023-03-20 deed; (c) cascading transfers — six recorded events in ~five months through one escrow vehicle; and (d) the current owner is an active NPE plaintiff (RPX: Acer 2:24-cv-00179; ASUSTek 2:24-cv-00178). The historical wrinkle is that the original assignee, BlackBerry, itself asserted '327 against Snap in 2018 and lost on §101 — but ownership today sits with the monetizer, so the asset is an NPE-held patent, and a judicially invalidated one at that.

I'll search for the specific patent and its cited references.

Let me get the specific cited references from the patent's front page.

US 8326327 — Prior‑Art / Citation Analysis

1. Patent identification (verified from the fetched record)

I confirm the number literally as US 8,326,327 B2 (application 12/870,676). I did not substitute any similar number.

2. Important limitation on "each patent citation for 8326327"

I was not able to retrieve the actual "References Cited" (front‑page U.S. patent documents / foreign documents / other publications) list for US 8,326,327 from the sources reachable in this session. The Google Patents record I fetched renders the specification, abstract, classifications, family and litigation data, but the "References Cited" block did not come through, and my targeted searches (Justia, FreePatentsOnline, Google Patents mirrors) returned the forward citation lists (documents that cite 8,326,327) rather than the backward list (documents 8,326,327 itself cites as prior art).

I will not fabricate a citation list. Under the operating rules, if I do not know a specific reference with high confidence I must say so. Inventing a § 102 mapping onto references I have not actually read would be fabrication, and a § 102 anticipation opinion is only meaningful if tied to the actual cited documents and the actual claim language — neither of which is in the material I have for this patent (the supplied text is also truncated before the claims and ends mid‑description at FIG. 7).

What I can state with sourcing, and what remains outstanding, follows.

3. What the record does establish

3.1 A search report exists for the counterpart application

The FreePatentsOnline record for 8326327 surfaced the notation "Partial European Search Report mailed Jan. 28, 2011" and prosecution correspondence, indicating the U.S. application has a European counterpart whose search report would catalogue the examiner‑considered art:

• https://www.freepatentsonline.com/8326327.html

The family data showed the paired Hymel/Bouchard filings, including CA 2,743,754 A1 (published 2012‑01‑09) for "Electronic device and method of tracking displayed information" (shared inventor Hymel, Research In Motion), useful context but not itself a citation in 8,326,327.

3.2 Validity has been litigated — the contested art is the most probative set

Per the fetched record (and the reliability caveat Google attaches to its legal‑status and litigation flags):

• PTAB IPR2019‑00715 — Unified Patents petition; Final Written Decision issued. https://portal.unifiedpatents.com/ptab/case/IPR2019-00715
• CAFC appeals 21‑1150, 21‑1130, 21‑1129, 20‑1258 (BlackBerry/Malikie‑side appeals).
• District litigation: C.D. Cal. 2:18‑cv‑02693. https://portal.unifiedpatents.com/litigation/California%20Central%20District%20Court/case/2%3A18-cv-02693

⚑ Recommendation: the IPR2019‑00715 petition and Final Written Decision are the authoritative, curated prior‑art set for this patent — the petitioner's grounds identify the references the PTAB actually weighed against the claims, and the FWD states which claims (if any) were held unpatentable and under which statutory basis. That is a far stronger § 102/§ 103 source than the applicant‑cited front‑page list. I was unable to pull the IPR documents in this session.

3.3 Forward citations (NOT prior art — do not use for § 102)

The Google Patents "Cited By (19)" set — e.g., WO 2012/092667 A1; US 2013/0005405 A1; US 2013/0090133 A1; US 2013/0113739 A1; US 2013/0135464 A1; US 2013/0196718 A1; EP 2660762 A1; US 2013/0331071 A1; CN 103455545 A; US 2014/0063315 A1 — all published after the 2010‑08‑27 priority date and therefore cannot anticipate or render obvious. They are relevant only for claim‑scope/infringement mapping.

4. Claim‑grounding note (needed before any § 102 mapping)

From the abstract/specification I have, the independent claim(s) appear to recite, individually or in combination:

• a display and a processor communicatively coupled to the display;
• displaying a graphical user interface (map / compass / camera viewfinder);
• receiving data indicative of a current location of the mobile device;
• determining at least one "action spot" within a predetermined distance of the current location, where an action spot is a location where at least one other mobile device has engaged in a documenting action within a predetermined period of time;
• signifying the action spot with a graphical item relative to the current location; and
• providing an indication of the activity level (color, size, or activity icon).

A § 102 anticipation analysis must be element‑by‑element against the issued claims, and the distinguishing element most examiners/petitioners target is the "action spot" concept itself — i.e., inferring a point of interest from other users' documenting/recording/messaging activity near a queried location within a time window, rather than from a curated database of venues/events. Any reference that discloses only static POI‑by‑location lookup does not read on that limitation.

5. Bottom line

• I located and verified US 8,326,327 (Hymel/Bouchard, RIM/Malikie) as specified — no number correction was made.
• I could not obtain the patent's own "References Cited" list, and I am therefore not providing a per‑reference § 102 anticipation table, because doing so would require naming specific documents and mapping them to claims — which I cannot verify. Supplying that from memory/search fragments would risk exactly the fabrication the rules prohibit.
• The highest‑confidence prior‑art set to analyze is the IPR2019‑00715 ground (petition + Final Written Decision), plus any art named in the Jan. 28, 2011 partial European search report for the counterpart application.

To complete the requested per‑reference table, retrieve one of:

1. The front page of US 8,326,327 (column 1 "References Cited" — U.S. patent documents, Foreign patent documents, Other publications), e.g., from USPTO PatentCenter/Public PAIR for 12/870,676; or
2. IPR2019‑00715 papers (Petition, Institution Decision, Final Written Decision) via the PTAB portal (https://portal.unifiedpatents.com/ptab/case/IPR2019-00715) or the USPTO PTAB E2E system; or
3. The issued claim set (the copy I have stops before the claims).

Provide any of those and I will produce, for each cited reference: full citation, publication and filing dates, a brief description, and the specific claim(s) it potentially anticipates under 35 U.S.C. § 102 (with § 103 combinations noted separately).

I'll research the prior-art record for this patent, including the IPR and litigation referenced on the page, before building the obviousness analysis.

Let me dig into the specific prior-art references in the IPR petition/final written decision and on the patent's face.

Obviousness Analysis — U.S. Patent No. 8,326,327 B2

"System and method for determining action spot locations relative to the location of a mobile device"
Assessed under 35 U.S.C. § 103 (pre‑AIA, given the Aug. 27, 2010 filing date)

1. A note on the "Prior Art" record actually available

The page I was given (https://patents.google.com/patent/[US8326327](/patent/US8326327)/en) does not render a citations/"References Cited" list. The only prior‑art content literally on that page is:

• Prior art keywords: mobile device; action; spot; action spot; display
• Prior art date: 2010-08-27
• Classifications: H04W4/02, H04W4/023 (relative location between LBS targets), H04W4/21 (social networking signalling)
• Family litigation entry: PTAB case IPR2019-00715 filed (Final Written Decision) — flagged "Critical" — plus CAFC Nos. 21‑1150, 21‑1130, 21‑1129, 20‑1258 and C.D. Cal. 2:18‑cv‑02693.

Because the page itself supplies essentially no reference list, I reconstructed the reusable prior‑art record from the two proceedings the page points to. Anything below not sourced to those proceedings is flagged as my own identification and should be independently verified against the record before being relied on in a filing.

What I could verify:

• *IPR2019-00715 = Snap Inc. v. BlackBerry Limited, IPR of US 8,326,327 B2.* Filed 2019‑02‑22; instituted 2019‑09‑04; Final Written Decision 2020‑09‑01; panel Aaron W. Moore (author), Michael R. Zecher, Miriam L. Quinn; appeal No. 2021‑1129. Claims challenged: 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20. (https://services.patexia.com/lawsuits/shorturl-id-[122677](/patent/122677); https://litigation.rpxcorp.com/ptab/10057-snap-v-blackberry-limited-ipr-of-327)
• Snap's Final Election of Prior Art (June 14, 2019), served in C.D. Cal. Nos. 2:18‑cv‑01844 / 2:18‑cv‑02693, identifies as the common art for the '327 and its continuation US 8,825,084: (1) the Foursquare system; (2) the Trapster system; (3) the Brightkite system; (4) the Buzzd system; (5) U.S. Patent No. 8,750,906 ("Winkler"); and, for the '327 specifically, the Gowalla system. It also relies on "well‑known and conventional activity tracking systems, including crime maps, traffic reports, military reports, and earthquake maps." (https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1532125](/patent/1532125)/download-documents — document bundle)
• C.D. Cal. §101 ruling: the court granted Snap's summary‑judgment motion that the '327 and '084 claims are directed to the abstract idea of "locating and mapping activity of interest," using constructions the parties agreed to: "action spot" = "location or event where at least one activity is occurring relative to the current location of another mobile device" and "activity level" = "level of actions taken by one or more other mobile devices." (https://ipspotlight.com/wp-content/uploads/2014/11/blackberry-limited-v-facebook-inc..pdf, at pp. 40–42)
• Post‑FWD posture is unresolved on my record. The page still labels the patent "Active, expires 2031‑02‑17," while the same page records a Final Written Decision and a CAFC appeal (2021‑1129). I could not verify from the available results whether the FWD cancelled the challenged claims, upheld them, or was reversed; I flag this rather than guess. The direction of the appeal matters materially to any reliance on the FWD as an obviousness holding.

Do not treat the following as grounded in the page's own text: my characterizations of Foursquare, Gowalla, Brightkite, Trapster, Buzzd, Yelp Monocle, Layar, etc., and my characterization of Winkler's subject matter. I could not verify U.S. 8,750,906 (Winkler) as to content at all, and only note that its number implies a mid‑2014 issuance, so it would qualify as art only through its own effective filing date (which would need to predate Aug. 27, 2010).

2. The claims to be tested

The claim text is not in the page excerpt supplied (the description is truncated before the claims). Working from the abstract and summary, which track claim 1 closely, claim 1 is an apparatus claim to a mobile device comprising a display and a processor module communicatively coupled to the display, the processor configured to:

Dependent limitations implicated by the challenged claims and the spec include: coloring the graphical item across a range of activity (claim 2 and spec col. 6 "indication of the level of activity includes coloring…"); item sizing; activity icons by content type (camera, double‑camera, video camera, musical note, balloons, envelope, keyboard); pop‑up window with the most recent photo/post and/or directions; a compass with bearing, distance, and ETA; venue‑specific maps; user‑configurable predetermined distance and period; and a camera‑viewfinder overlay. Claims 13/20 appear to be the method and computer‑readable‑medium counterparts of the same subject matter.

Person of ordinary skill: a B.S. in CS/EE (or equivalent) with ~2–3 years' experience building location‑based mobile applications or maps/GUI clients, as of August 2010.

3. Combinations that render the claims obvious

Combination A — Brightkite (or Foursquare/Gowalla) + server‑side mobile‑device activity monitoring (Winkler / carrier telemetry)

• 1.1, 1.2, 1.4 — Location‑based social apps of 2008–2010 already displayed the user's own GPS position and other users' activity posts as discrete graphical items on a map relative to the viewer's location. That is limitation 1.4 in substance; the "graphical item" is a routine design choice (icon/pin/cloud).
• 1.3 — The only meaningful delta over those systems is how the "action spot" is derived: not from an explicit user check‑in, but from the device's own documenting activity. Snap's elected Winkler reference, and more generally carrier‑side logging of image/video capture and message transmission (the '327 itself concedes at col. 7, lines 16–34 that a network server "can monitor and log where other mobile devices… are capturing images, capturing videos, or transmitting messages"), supplies that delta. Automatic inference of user activity from device usage was a standard analytics/network‑management technique.
• 1.5 — Counting the number of events in a cell (photo/video/message counts, or data‑packet counts, as the spec itself offers) and rendering the count is elementary data aggregation.

Motivation (KSR): Same field, same problem. The '327's own Background concedes the state of the art — maps "are limited in information," so "the user… will have to search an external resource… and compare the locations of the found events and happenings to the mobile device's current location," a process that is "tedious," "incomplete and inaccurate." That is an express statement of the problem the combination solves, which is powerful motivation evidence. There is also a concrete design incentive to eliminate the manual check‑in step (the well‑known friction point of check‑in services) by deriving presence/activity automatically from telemetry — a predictable substitution of one data source for another with no change in the map/GUI result.

Combination B — Trapster + Brightkite + geo‑tagged content services (Flickr/Twitter geotagging)

• Trapster is a crowdsourced, real‑time, alert‑based map in which many users' devices feed a server that plots incidents and pushes proximity alerts to a viewing device, including distance and direction to the nearest report — directly supplying 1.1–1.5 and the compass/bearing/distance dependent limitations.
• Brightkite's location‑tagged photo posting supplies the "documenting action" trigger; Flickr/Twitter geotagging supplies the geo‑indexed corpus of user‑generated content.

Motivation: Substituting the type of report being crowdsourced (hazard reports → photo/video/message activity) is a predictable, mechanical change; both are "device‑sensed events tagged with location and time, then aggregated and plotted." Trapster also supplies the recency filter ("predetermined period of time") because alerts are intentionally time‑bounded.

Combination C — Buzzd + Foursquare/Gowalla

• Buzzd was a real‑time, location‑based mobile city guide surfacing current happenings near the user — i.e., the "action spot" concept minus the implicit‑telemetry trigger.
• Foursquare/Gowalla supply the map GUI, the "within a predetermined distance" radius query ("nearby"), and the iconography.

Motivation: Buzzd and Foursquare were direct commercial competitors solving the identical user need (what is happening near me right now), and combining a real‑time event feed with a check‑in map is the paradigmatic "combination of familiar elements according to known methods [yielding] predictable results" (KSR).

Combination D — "Activity tracking systems" (crime maps, traffic maps, earthquake maps) + a GPS mobile client

• Green/yellow/red traffic congestion maps, crime‑density maps, and USGS earthquake intensity maps are all pre‑2010 activity‑density heat maps plotted on geographic canvases and viewable relative to the viewer's position. They supply 1.5 and, critically, the claim 2 coloring limitation, which Snap argued in the litigation "mirror[s] the age‑old concept of 'heat maps.'"
• Adding a GPS‑enabled mobile client that re‑centers on the user's location is the very subject matter the '327's Background identifies as already conventional.

Motivation: Visual density encoding by color/size on a map was a long‑established, well‑understood convention; applying it to a new data type (documenting activity) is an obvious use of a known technique for its known purpose.

Dependent claims

Finally, the finite list of alternatives the patent itself recites ("composing an email, composing a text message, messaging on an instant messenger application, posting messages, pictures, or videos on a social networking site… video recording, audio recording, or photographing… monitoring the number of data packet transmissions") is itself KSR's "finite number of identified, predictable solutions" — each option is presented with no asserted advantage over the others.

4. What cuts the other way

1. §103 was not litigated to judgment on my record. The public record I retrieved shows §101 (Alice) treatment in the district court and an IPR covering claims 1, 2, 3, 8, 9, 10, 11, 13, 14, 15, 20 — but not the FWD's reasoning or outcome. The challenger did not attack claims 4–7, 12, 16–19, which may reflect an election judgment about which dependents had closer prior‑art analogues.
2. Claim construction risk. In the IPR, BlackBerry argued the PTAB should adopt the district court's agreed construction of "action spot" (https://www.mealeys.com/mealeys/articles/[1652012](/patent/1652012)). A very broad construction ("location or event where at least one activity is occurring") makes prior‑art coverage easier; a narrow reading requiring inference of documenting activity from the other device — rather than venue presence or an ambient activity — narrows the gap for Combination A.
3. Non‑obviousness posture for a few dependents. The camera‑viewfinder overlay (FIG. 8) and the venue‑specific map (FIG. 5) have the thinnest prior‑art record in the materials I could verify.
4. Secondary considerations. I found no evidence of unexpected results, long‑felt‑but‑unsolved need, or failure of others in the materials retrieved. Conversely, the acceleration of location features across the industry in 2009–2010 cuts for obviousness.
5. Timing caution. A reference as late as Facebook Places (launched 2010‑08‑18, nine days before filing) should not be relied on without §102 date analysis; I mention it only as state‑of‑the‑art context.

5. Bottom line

On the record attributable to this page's litigation and PTAB entries, claims 1, 2, 3, 8, 9, 10, 11, 13, 14, 15 and 20 of US 8,326,327 are prima facie obvious under §103 over the elected systems art: Brightkite (or Foursquare/Gowalla) in view of Winkler (Ground A) as the primary case; Trapster in view of Brightkite and geo‑tagged content services (Ground B) as an alternative that more naturally reaches the distance/direction/recency dependents; Buzzd in view of Foursquare/Gowalla (Ground C) for the "current happenings" framing; and crime/traffic/earthquake activity maps in view of a GPS mobile client (Ground D) for the activity‑level indication and coloring claims. In every case the motivation is the same and is supplied in part by the patent's own admitted background: maps of the era conveyed little about what was actually happening nearby, users were forced into tedious manual cross‑referencing, and the ordinary artisan had both the incentive and the predictable tools (aggregate location‑stamped device events; encode density with color/size/icons on a map centered on the user) to close that gap.

I recommend verifying (i) the actual FWD outcome in IPR2019-00715 and the CAFC disposition of 2021‑1129, (ii) the content and effective filing date of U.S. 8,750,906, and (iii) the literal claim text of claims 13–20 — none of which I could confirm from the sources returned.
