US 8209634

I'll search for authoritative information on this specific patent number, then synthesize with the full patent text provided.

Let me check for Federal Circuit activity and the litigation background.

Let me check the PTAB outcome and any 2026 appellate activity.

US Patent 8,209,634 — Analyst Summary

Search scope note: I searched for the literal number 8209634 (and its standard comma-delimited rendering 8,209,634). No Federal Circuit 2026 docket entry for this patent surfaced in any result. The only Federal Circuit dockets identified are 20‑1256, 20‑1258, and 21‑1377 (see Litigation section).

2. Abstract (verbatim)

"Method and apparatus for previewing new events in a computing device having a plurality of applications for managing respective events are described. Individual applications are each represented by an application icon on a screen of a graphical user interface for the device. When a new event occurs, particularly when the new event relates to a specific one of a plurality of similar applications, the invention provides a convenient way to denote which application relates to the event. In response to a new event of a one of the applications, the application's icon is visually modified to notify of the new event. A visual modification may be determined in response to the new event, for example, to preview a content of the event. The visual modification may include a count of all new events that remain to be disposed. On a selection of the visually modified icon, additional previewing may be provided. Activation of the application having a visually modified application icon may be configured to automatically initiate the application at the new event."

3. Independent claims — plain language

The issued patent has 18 claims, with three independent claims: 1 (method), 7 (computer-readable memory), and 13 (device). All three recite the same core inventive step.

Claim 1 — Method of providing notifications of unread messages on a wireless communication device

Three steps:

1. Display at least one icon relating to electronic messaging on the device's GUI.
2. Receive a plurality of electronic messages on the device, where those messages come from a plurality of different messaging correspondents.
3. In response to receiving at least one of those messages, visually modify the displayed icon to include a numeric character representing a count of the plurality of different messaging correspondents for which one or more messages have been received and remain unread.

Key narrowing point: the number shown is a count of distinct correspondents/senders with unread mail — not a raw count of unread messages. This is materially different from the parent specification's broader disclosure ("a numeric indicator '1' representing a count of new events… unread messages"). The patent's own spec explicitly contemplates this alternative: "for application icon 304 it may identify the number of distinct senders of unread IM messages and for application icon 308 distinct unread IM messages." During prosecution the examiner had cited a Nokia 9210i Communicator webpage, and this correspondent-count limitation is what distinguishes claim 1.

Claim 7 — Computer-readable memory

A processor-accessible memory storing executable data structures that, when run, cause a wireless communication device to perform the identical three steps of claim 1 (display messaging icon → receive messages from multiple different correspondents → visually modify the icon to include a numeric character counting the distinct correspondents having one or more unread messages).

Claim 13 — Wireless communication device

A device comprising: (a) a processor; (b) a display electrically coupled to the processor and presenting a GUI; and (c) memory storing machine-readable instructions to perform the identical three steps of claim 1. This is the apparatus counterpart of claim 1 and mirrors claim 7's functionality, but claims the hardware combination (processor + display + memory) rather than the memory alone.

Net effect of the three independents: claim 1 covers the method, claim 7 covers software/CRM (instructions), and claim 13 covers the physical handheld device performing all three steps.

4. Dependent claims (brief)

Claims 5–6 and 11–12/17–18 correspond to the FIG. 6 dialog-box preview (service name "AIM," sender "red98," message excerpt) and the FIG. 7 multiple-preview embodiment.

5. Litigation, PTAB, and post-grant status

District court. BlackBerry sued Facebook, WhatsApp, and Instagram (C.D. Cal. No. 2:18‑cv‑01844‑GW‑KS) and Snap (No. 2:18‑cv‑02693‑GW‑KS) in 2018. '634 was one of nine asserted patents against Facebook and one of six against Snap. Reported coverage: https://ipwatchdog.com/2018/03/24/blackberry-sues-facebook-instagram-whatsapp-patent-infringement/ and https://portal.unifiedpatents.com/litigation/California%20Central%20District%20Court/case/2%3A18-cv-01844

Claim construction. In the joint claim construction statement, the parties disputed three '634 terms: "wireless communication device" (BlackBerry: "small-screen wireless mobile device" vs. defendants: no construction/〝device that can communicate without wires〞); "icon" (BlackBerry: "picture or symbol representing a computer application or function" vs. "graphical image"); and "messaging correspondent" (BlackBerry: "distinct sender of an electronic message to the user of the wireless communication device" vs. "a person from whom messages may be received").

PTAB — four petitions against '634:

• IPR2019‑00924 (Facebook) — institution denied (Oct 9, 2019).
• IPR2019‑00925 (Facebook) — instituted Oct 16, 2019; Final Written Decision Oct 1, 2020 determining all challenged claims unpatentable (claims 1, 4, 5, 6, 7, 10–11, 12, 13, 16–18).
• IPR2019‑00938 (Snap) — instituted with joinder to ‑00925; terminated Nov 2019 after settlement.
• IPR2019‑00939 (Snap) — institution denied (Oct 9, 2019).

Federal Circuit.

• 20‑1256 and 20‑1258 — BlackBerry's appeals from the §101 (Alice) invalidity rulings on other patents in the Facebook/Snap suits. Reported Dec 10, 2020: "Fed. Circ. Refuses To Revive BlackBerry Patent Claims."
• 21‑1377 — the appeal associated with IPR2019‑00925 (the '634 Final Written Decision).

Overall case end. BlackBerry and Facebook settled/dropped the patent fight in January 2021 (Law360: "BlackBerry, Facebook Drop Patent Fight Over Messaging Tech").

Family. The '634 family includes continuations US 8,631,353 B2 (expired‑fee‑related), US 9,830,045 B2 (recorded active to 2027‑09‑22), and US 11,740,763 B2 (issued 2023‑08‑29, recorded "Expired ‑ Lifetime"). Foreign counterparts exist in EP, JP (JP4651623B2), KR (KR100871404B1), CN, CA, DE, ES, SG, and WO 2005/055034 A1.

6. Explicit uncertainty flags

1. Patent number rendering. Records render the number variably as 8209634, 8,209,634, and US 8,209,634 B2. These are the same patent with standard U.S. comma grouping. I did not treat the string 8209634 found in unrelated documents (e.g., GB 2 117 903 A's priority number, or FR 8,209,634) as this patent — those are different jurisdictions and are excluded.
2. Status conflict — flag this. Google Patents lists the patent as "Active," expiring 2026‑11‑07, yet PTAB IPR2019‑00925 issued a Final Written Decision holding all challenged claims unpatentable (Oct 1, 2020), with a Federal Circuit appeal (21‑1377). These cannot both be fully accurate absent a reversal, vacatur, or an unrecorded/erroneous status entry. I could not confirm the disposition of CAFC 21‑1377 from the search results available, so I cannot state with confidence whether the '634 claims currently stand, are cancelled, or were restored on appeal. Treat the "Active" status as unverified.
3. No 2026 CAFC docket found. My searches for 2026 Federal Circuit activity on this patent returned nothing. If a 2026 docket exists, it was not captured in the retrieved results — this is a negative search result, not proof of absence.
4. Claim characterization mismatch in secondary sources. IPWatchdog's 2018 article describes claim 1 as showing "a numeric number representing a count of received messages that have gone unread." The authoritative claim text instead recites a count of different messaging correspondents. Where the secondary source and the patent text conflict, I have followed the patent text.
5. Claim-count variance. Some PTAB documents refer to claims 1, 4–7, 10–13, 16–18 as challenged — consistent with the 18-claim issued set I have. I have not independently verified that the issued claim set matches the Google Patents transcription in every dependent-claim dependency.

I'll research litigation involving US patent 8209634 across patent litigation databases.

Good results. Let me dig deeper into the specific district court and CAFC cases.

Litigation involving U.S. Patent No. 8,209,634

Based on the litigation databases and court records I reviewed (Unified Patents litigation portal, CourtListener/RECAP dockets, Docket Alarm/PTAB records, and the Google Patents "litigation" panel for US8209634), here is what is known. I did not include results for similarly-numbered patents.

My search results did not surface the full party/caption and disposition details, and I could not confirm from a primary source in this session whether the '634 patent was specifically at issue on appeal (the judgment encompassed multiple patents). I cannot state the outcome of 20-1256 and 20-1258 with confidence — treat these as registered appeals from the BlackBerry v. Facebook C.D. Cal. case that should be verified against the Federal Circuit docket.

Summary of the '634 patent's litigation fate

• Two district court suits: BlackBerry v. Facebook/WhatsApp/Instagram (C.D. Cal. 2:18-cv-01844) and BlackBerry v. Snap (C.D. Cal. 2:18-cv-02693).
  • Against Snap, the '634 claims were dismissed with prejudice by stipulation (final judgment Nov. 15, 2019).
  • Against Facebook/WhatsApp/Instagram, the '634 claims were held invalid under § 101 and non-infringed on summary judgment (2020).
• Four IPRs were filed on the '634 patent in April 2019: two by Facebook/Instagram/WhatsApp (one instituted → claims unpatentable; one not instituted) and two by Snap (one settled/terminated; one not instituted).
• The Federal Circuit appeal from the instituted IPR (21-1377) was voluntarily dismissed in February 2021.

Caveats: (1) I could not independently verify the disposition/caption of Federal Circuit Nos. 20-1256 and 20-1258 within the constraints of this session — please confirm via the CAFC docket. (2) The C.D. Cal. dockets remained active into 2020; I did not verify a single "final judgment" docket entry for 2:18-cv-01844 as to the '634 patent beyond the summary-judgment rulings cited. (3) Patent numbers/identifiers above were taken literally from the sources and not auto-corrected.

I'll research the PTAB proceedings referenced on this patent's record, since the structured "on file" block and the patent's own litigation panel contradict each other.

⚠️ Threshold contradiction to flag first

The structured "PTAB proceedings on file" block in this task states that "the USPTO ODP API returns no AIA trial proceedings for this patent… the default should be 'no PTAB activity on file.'"

That is wrong for US 8,209,634. The patent's own Google Patents page lists four PTAB cases, and three independent docket sources (Docket Alarm OCR search for patent:(8209634), the Ex Parte PTAB mirror, and Patexia's litigation/lawsuits database) confirm all four as real, docketed IPRs. The ODP ingest evidently missed the 2019 trial filings. I proceed on the four proceedings below and treat the "no activity" default as a data error — not as evidence of a clean patent record. (Per the operating rules, I have not auto-corrected the identifier; the discrepancy is in the data source, not the patent number.)

Proceedings overview

Four AIA trials were filed on US 8,209,634 — all in April 2019, all Inter Partes Review, all before the same three-judge panel. One went to a Final Written Decision that held every challenged claim unpatentable; one was instituted and then terminated on settlement after the petitioner joined the first trial; two were denied institution. The bottom line for a defendant today: claims 1, 4–7, 10–13, and 16–18 of the '634 patent are canceled, and the six never-challenged claims (2, 3, 8, 9, 14, 15) all depend from canceled independent claims 1, 7, and 13 — there is no live claim left to assert. This is the opposite of a "hardened" patent.

IPR2019-00925 — Facebook, Inc., Instagram, LLC & WhatsApp Inc. v. BlackBerry Limited

• Type: Inter Partes Review (35 U.S.C. §§ 311–319)
• Filed: 2019-04-04
• Status: Final Written Decision (Paper 38, entered 2020-10-01) — "Final Written Decision Determining All Claims Unpatentable"
• Judge panel: Gregg I. Anderson, Miriam L. Quinn, Robert L. Kinder (per Docket Alarm and Patexia; third-party records list Quinn as opinion author across the related '634 proceedings, though I could not verify authorship of this particular FWD from a primary source)
• Petition grounds (all § 103(a) obviousness — no § 102 or § 112 grounds were asserted):
  • Ground 1 — claims 1, 4, 5, 7, 10, 11, 13, 16, 17 obvious over Ording (US 7,434,177) in view of Abiko (US 2002/0142758 A1), Crumlish (The ABCs of the Internet, 1996), and Dvorak ("Scarier than Spam," PC Magazine, 1999-01-19).
  • Ground 2 — claims 6, 12, 18 obvious over the Ground 1 combination further in view of McPherson (How to Do Everything with Your Pocket PC, 2d ed. 2002).
  • Grounds 3–4 — mirror grounds adding Strom ("Three New Wireless E-Mail Devices," Computerworld, 1999-11-08), pleaded to pre-empt a narrow reading of "wireless communication device" as requiring a small screen.
• Core merits theory: Ording supplied the numeric "badge" superimposed on an application icon; Abiko supplied counting of distinct senders rather than raw message counts; Crumlish showed segregating unread messages; McPherson showed a content preview notification bubble (MSN Messenger on Pocket PC). Petitioner also attacked BlackBerry's litigation-driven construction of "wireless communication device," pointing to the prosecution history where a "small display" limitation was added and later canceled.
• Institution decision: Instituted 2019-10-16. Petitioner also had to defend against discretionary denial under § 314(a), arguing that its simultaneous second petition (IPR2019-00924), filed the same day on different art, was not a General Plastic "follow-on."
• Final Written Decision — claim-level verdict: Claims 1, 4, 5, 7, 10, 11, 13, 16, and 17 unpatentable under § 103(a) over Ording, Abiko, and Dvorak. Claims 6, 12, and 18 unpatentable under § 103(a) over Ording, Abiko, Dvorak, and McPherson. That is the complete set of challenged claims — 12 of 12 claims canceled, zero claims sustained. The FWD is at USPTO PTAB E2E, IPR2019-00925 Paper 38 (2020-10-01); a copy is indexed at https://ocr.docketalarm.com/search/?q=patent:([8209634](/patent/8209634)).
• Settlement / termination: none — decided on the merits.
• Appeal: Yes. BlackBerry filed a Notice of Appeal on 2020-12-03 (Paper 39). Docketed at the Federal Circuit as BlackBerry Ltd. v. Facebook, Inc., No. 2021-1377. The stated issues included the § 103(a) holdings on both grounds, "the Board's interpretation of the prior art," "the Board's failure to consider evidence of record fully and properly," and a constitutional challenge to the appointment of the Administrative Patent Judges. The appeal was voluntarily dismissed on BlackBerry's motion under FRAP 42(b); mandate issued 2021-02-26 (https://portal.unifiedpatents.com/litigation/Court%20of%20Appeals%20for%20the%20Federal%20Circuit/case/2021-1377). Because no merits decision ever issued on appeal, the FWD is final and its cancellation of claims 1, 4–7, 10–13, 16–18 stands.
• Defensive value: Decisive. Every claim BlackBerry could have asserted from the '634 patent — the three independents (1, 7, 13) and nine dependents — was held unpatentable and that judgment is now final. Any demand letter citing '634 claims 1, 4–7, 10–13, 16–18 is asserting canceled claims. A newly-sued defendant should not need an IPR at all; the primary defensive move is to put the FWD and the resulting cancellation in front of plaintiff's counsel and the court.

IPR2019-00938 — Snap Inc. v. BlackBerry Limited

• Type: Inter Partes Review
• Filed: 2019-04-05
• Status: Terminated-Settled (Order, 2019-11-26: "Termination of Snap Inc. Due to Settlement After Institution of Trial", Paper 14)
• Judge panel: Gregg I. Anderson, Miriam L. Quinn, Robert L. Kinder
• Petition grounds: the same 12 claims (1, 4, 5, 6, 7, 10, 11, 12, 13, 16, 17, 18) on the same art as IPR2019-00925 — Snap's exhibit list (EX-1103 Ording, EX-1109 Abiko, EX-1110 Crumlish, EX-1111 Dvorak, EX-1112 McPherson, EX-1115 Strom) is substantively identical to the Facebook petition's.
• Institution decision: Instituted 2019-10-17 — and Snap's Motion for Joinder to IPR2019-00925 was granted (Paper 11, "Decision — Institution of Inter Partes Review and Grant of Motion for Joinder"). This was a parallel "me-too" petition, not an independent merits challenge.
• Final Written Decision: none. The proceeding was terminated before any FWD.
• Settlement / termination: The parties executed a confidential settlement agreement effective 2019-11-13 and jointly moved to terminate on 2019-11-19 under 35 U.S.C. § 317(a) and 37 C.F.R. § 42.74. Terms are confidential; the agreement was filed as Confidential Exhibit 1126 with a request under § 42.74(c) that it be kept separate from the patent file. The motion records that BlackBerry agreed to dismiss its '634 claims against Snap with prejudice in BlackBerry Ltd. v. Snap Inc., C.D. Cal. No. 2:18-cv-02693. The Board expressly noted the termination did not affect IPR2019-00925, which proceeded against Facebook/Instagram/WhatsApp.

• Appeal: none (no FWD to appeal).
• Defensive value: Modest on its own, but it confirms the pattern: Snap elected to settle and take a with-prejudice dismissal of the '634 claims rather than defend, and deliberately rode the Facebook trial via joinder rather than litigate its own. It also means Snap is not a source of a second, independent validity ruling to cite — the estoppel and record value here flow from IPR2019-00925.

IPR2019-00924 — Facebook, Inc., Instagram, LLC & WhatsApp Inc. v. BlackBerry Limited

• Type: Inter Partes Review
• Filed: 2019-04-04
• Status: Institution Denied (petition denied; the patent's Google Patents panel labels it "Not Instituted – Merits," i.e., the denial rested on the petition's substantive failure rather than a discretionary § 314(a)/§ 325(d) denial — that labeling is from the Google Patents literature and I could not verify the panel's verbatim reasoning in the sources available to me)
• Judge panel: Gregg I. Anderson, Miriam L. Quinn, Robert L. Kinder
• Petition grounds: claims 1, 4, 5, 6, 7, 10, 11, 12, 13, 16, 17, 18, on different prior art than IPR2019-00925 (petitioner represented that the two same-day petitions relied on "entirely different prior art references" and were split only to stay within the Board's word limits).
• Institution decision: denied. ⚠️ Caveat: I could not retrieve the text of the 2019-10-09 decision, so I will not characterize the Board's specific reasoning beyond the "merits" label above.
• Final Written Decision: none.
• Settlement / termination: n/a.
• Appeal: none.
• Defensive value: Limited but useful pattern evidence — the same day the Board instituted on the Ording/Abiko/Dvorak theory, it refused to institute on the alternative art set. For a defendant weighing a new IPR, that tells you the winning art is the Ording combination, and that the Board is not receptive to a differently-art-ed second bite on the same claims.

IPR2019-00939 — Snap Inc. v. BlackBerry Limited

• Type: Inter Partes Review
• Filed: 2019-04-05
• Status: Institution Denied (Google Patents panel label: "Not Instituted – Merits")
• Judge panel: Gregg I. Anderson, Miriam L. Quinn, Robert L. Kinder
• Petition grounds: claims 1, 4, 5, 6, 7, 10, 11, 12, 13, 16, 17, 18 — the mirror of Snap's joinder petition in IPR2019-00938, on alternative art.
• Institution decision: denied. ⚠️ Same caveat as IPR2019-00924 — I could not obtain the decision text and will not invent its reasoning.
• Final Written Decision: none.
• Settlement / termination: n/a.
• Appeal: none.
• Defensive value: Confirms that of the four petitions filed against this patent, only two were even instituted, and both were on the same Ording/Abiko/Dvorak theory. Alternative-art attacks on the '634 claims were rejected at the threshold twice.

Strategic summary

Claim status. Of the 18 claims in the '634 patent, twelve are canceled by a final, unappealed FWD: 1, 4, 5, 6, 7, 10, 11, 12, 13, 16, 17, and 18. The six never-challenged claims (2, 3, 8, 9, 14, 15) are not a refuge: claim 2 depends from claim 1 and claim 3 depends from claim 2; claim 8 depends from claim 7 and claim 9 from claim 8; claims 14 and 15 depend from claim 13 (14 directly, 15 via 14). With independent claims 1, 7, and 13 canceled, every remaining claim is invalid by dependency and cannot be separately asserted. The '634 patent has no assertable claim. (Note the contrast with sibling patents in the same C.D. Cal. campaign: e.g., in the '929 IPR BlackBerry affirmatively disclaimed claims mid-trial; here the claims were taken away by adjudication.) Note also that the Google Patents page still renders the pre-IPR 18-claim text and shows the patent as "Active" — that reflects PatentCenter's maintenance/expiration bookkeeping, not the survival of the claims. Do not rely on that page's claim set.

Estoppel landscape. § 315(e)(2) estops Facebook, Inc., Instagram, LLC, WhatsApp Inc., and Snap Inc. — and their real parties in interest and privies — from raising in district court any ground they raised or reasonably could have raised in IPR2019-00925 and IPR2019-00938. That covers Ording, Abiko, Crumlish, Dvorak, Strom, and McPherson. In practice this estoppel is academic: the claims themselves are gone. Estoppel does not run to third parties. A defendant newly sued on the '634 patent gets no benefit from that estoppel, but it also needs none — it can simply plead, and move to dismiss on, the fact of cancellation. The prior art below has not been exhausted for the family: continuation applications from the same 2003-12-01 priority chain matured as US 8,631,353 (filed 2012-01-26), US 9,830,045 (filed 2012-05-25), and US 11,740,763 (filed 2017-10-23). Those are separate patents with their own claim sets, and the Ording/Abiko/Dvorak combination has not (on the record I can see) been adjudicated against them.

Pattern signals. (1) Same panel, four times: Anderson, Quinn, and Kinder sat on all four '634 proceedings — as they did on sibling IPRs in the same campaign (e.g., the '929 FWD authored by Judge Kinder). (2) Two-petition filing pattern: both Facebook/Instagram/WhatsApp and Snap filed pairs of petitions on the same claims the same day; the Board instituted one from each pair and denied the other, then allowed Snap to join rather than run a second trial. (3) BlackBerry did appeal — aggressively enough to raise an Appointments Clause challenge — but voluntarily dismissed before the Federal Circuit reached the merits, consistent with the underlying commercial settlement. (4) No defensive aggregator: the "Unified Patents" string on the Google Patents page is a data-license attribution for the litigation feed, not a petitioner; the actual petitioners were the litigation adversaries themselves (Facebook/Instagram/WhatsApp and Snap). Do not describe this patent as having been hit by Unified Patents. (5) The CAFC Nos. 2020-1256 and 2020-1258 appeals listed on the Google panel arise from the district court case's Rule 54(b) judgments and relate to the '351 and '929 patents — they do not involve the '634 FWD.

Recommended next steps

1. If you are a defendant and BlackBerry (or any successor/assignee) asserts the '634 patent today, lead with the FWD, not with an IPR petition. Cite IPR2019-00925, Paper 38 (2020-10-01), Facebook, Inc. v. BlackBerry Limited, IPR2019-00925, "Final Written Decision Determining All Claims Unpatentable" — claims 1, 4, 5, 7, 10, 11, 13, 16, 17 unpatentable over Ording/Abiko/Dvorak and claims 6, 12, 18 unpatentable over Ording/Abiko/Dvorak/McPherson. Pull the paper from USPTO PTAB E2E (https://ptab.uspto.gov) or via https://ocr.docketalarm.com/search/?q=patent:(8209634). The appeal history — Notice of Appeal 2020-12-03, voluntary dismissal, mandate 2021-02-26 — closes the door on any argument that the judgment is unsettled.
2. Check the PTO's claim-status record before citing the patent's printed claims. If the cancellation certificate has issued, the asserted claims are literally gone from the patent; if PatentCenter still shows them, the FWD plus the § 318(b) certificate is your proof. Either way, never quote the pre-2020 claim text from the granted patent as if it were live.
3. If the demand letter names a different patent in the family (e.g., US 8,631,353, US 9,830,045, or US 11,740,763 — all continuations of the '634 with the same 2003-12-01 priority), the '634 FWD is not a complete defense. Run a fresh grounds analysis. The natural starting point is the exact combination that worked here — Ording (US 7,434,177) + Abiko (US 2002/0142758 A1) + Dvorak — plus McPherson if the new claims recite a content preview. Note the § 315(b) one-year clock: it runs from service of a complaint on your client, and it is not tolled by any prior petitioner's estoppel.
4. No active proceedings are pending. There is nothing on a trial clock: no institution deadline, no oral hearing, no statutory FWD due date. The four 2019 proceedings are all closed — three by final disposition, one by settlement. If a defendant filed a new IPR today, the filing would be assessed on its own merits and on the ordinary Fintiv/§ 314(a) discretionary factors.
5. Do not treat the "no PTAB activity on file" ingest result as informative. It is a data gap in the ODP snapshot, contradicted by four docketed proceedings. Verify anything you rely on against PTAB E2E or CourtListener rather than the aggregated feed.

I'll research the assignment/ownership record for US 8,209,634, focusing on USPTO Assignment Center records, reel/frame data, and correspondent of record.

Ownership & Assignment Reconstruction — US 8,209,634 ("Previewing a new event on a small screen device")

Source limitation (read first): I could not query https://assignmentcenter.uspto.gov/ directly in this session — it is a JavaScript application that the search tool cannot render, and no indexed mirror returned the reel/frame for application 10/784,781 specifically. What follows is built from (a) the Google Patents legal-events panel for US8209634 (which reports recorded reassignments with dates and party names but not reel/frame), and (b) Espacenet INPADOC legal-status records for sibling RIM applications in the same era, which do expose reel/frame. Where a reel/frame is from a sibling patent rather than from '634 itself, I say so explicitly and mark it unverified for this patent. I have not invented any reel number.

Inventors

Pattern assessment:

• The Dunk/Klassen pairing on a separate RIM instant-messaging filing (EP 1661037 family) is corroborating evidence that both men were RIM's Waterloo-based IM/UI software group, not outside contractors — relevant because the '634 is an IM/messaging-GUI invention. Source: EP register extract listing "HARDY, Michael, Thomas; DUNK, Craig, A.; KLASSEN, Gerhard, D." under applicant Research In Motion Limited.
• No unusual-departure pattern is discernible. I found no evidence of any of the three inventors leaving RIM within 12 months of the 2004‑02‑24 filing, and no evidence of any inventor-side assignment or subsequent inventor-owned filing. I could not date any of their departures at all — treat this as no data, not as no departures. There is no inventor-retention or inventor-resale signal here.
• All three inventors assigned to the corporate employer on filing (standard "ASSIGNMENT OF ASSIGNORS INTEREST" instrument), i.e. this was an employed-inventor portfolio filing, not an independently owned patent.

Original assignee

Research In Motion Limited (RIM), Waterloo, Ontario, Canada. Assignment recorded at the USPTO on 2004‑02‑24, the same date the application was filed; Google Patents legal events record "2004‑02‑24 Assigned to RESEARCH IN MOTION LIMITED … Assignors: DUNK, CRAIG A., KLASSEN, GERHARD D., WORMALD, CHRISTOPHER R."

• Line of business: designer/manufacturer of the BlackBerry handheld wireless email and messaging device — i.e. an operating company, and specifically an operating company whose product practised the claim. The '634 disclosure is expressly about rendering notification/preview of new messages on the small screen of that device.
• Did it ship a product embodying the claims? Yes. RIM shipped BlackBerry handhelds with a home screen showing per-application icons and unread-message counters from the early 2000s; RIM's own later litigation pleadings describe the BlackBerry device line as embodying its "mobile device user interfaces" inventions (see, e.g., BlackBerry Limited v. Avaya Inc., N.D. Tex. complaint, ¶¶21–24).
• Current status: operating. RIM is the same legal entity as today's BlackBerry Limited, following a shareholders' resolution approved at the annual and special meeting of 2013‑07‑09 to change the company's name. BlackBerry Limited is publicly traded (NYSE/TSX: BB) and has pivoted from hardware to enterprise software, cybersecurity, IoT/automotive embedded systems, and patent licensing. It has never filed Chapter 7/11. (Note: the sibling entity "Research In Motion Corporation" → "BlackBerry Corporation" is a separate US subsidiary; not relevant to the '634 chain.)

Assignment timeline

Only two conveyances are recorded against US 8,209,634 on the Google Patents legal-events panel. There is no security agreement, license, merger, release, or correction recorded. The chain is short and unencumbered.

1. 2004‑02‑24 (executed) / recorded 2004‑02‑24 — Reel not retrieved (unverified for this patent)

• Conveyance: Assignment — "ASSIGNMENT OF ASSIGNORS INTEREST"
• Assignor: Gerhard D. Klassen; Craig A. Dunk; Christopher R. Wormald (joint inventors)
• Assignee: Research In Motion Limited (Waterloo, Ontario, Canada)
• Correspondent: not retrievable in this session. *(Per your instructions this is the single most useful tell; it is unavailable for '634. For calibration only, a same-era RIM invention assignment for a different application — US 10/688,544, issued as US 7,584,254 — was recorded 2004‑03‑24 at reel 014458/0447, evidence that RIM's 2004-era recordings cluster in the 014xxx reel range. I have not assumed the '634 sits at any particular reel.)*
• Context: original assignment of employed-inventor rights to the corporation — ordinary portfolio intake, no encumbrance created.

2. Effective 2013‑07‑09 / recorded 2014‑10‑24 — Reel 034045/0741 (verified for sibling application US 10/688,544 / US 7,584,254; not independently verified for '634)

• Conveyance: Change of Name — "CHANGE OF NAME; ASSIGNOR: RESEARCH IN MOTION LIMITED"
• Assignor: Research In Motion Limited
• Assignee: BlackBerry Limited (Waterloo, Ontario)
• Correspondent: not retrievable in this session.
• Context: name change only — no change in beneficial ownership, no consideration, no transfer of assets. Google Patents' legal-events panel for '634 independently shows a 2014‑10‑24 "CHANGE OF NAME" recording with assignor Research In Motion Limited and assignee BlackBerry Limited, which is consistent with the 2014‑10‑24 recording date on the sibling patent. The 2014‑10‑24 date on both records is why I associate the two — but the reel number is inferred, not confirmed for '634, and is flagged as such.

Post-2014: nothing further is recorded against '634 in the sources I retrieved. In particular Google Patents continues to list BlackBerry Limited as the current assignee for both '634 and its continuation US 11,740,763. Note for completeness: BlackBerry announced a large patent-portfolio sale to Malikie Innovations Limited (a Key Patent Innovations affiliate) announced in 2023, and some BlackBerry patents now show Malikie as assignee (e.g. the Indian application discussed in BlackBerry Limited v. Controller of Patents, Delhi HC, 2024). I found no recorded assignment of '634 to Malikie Innovations Limited and Google Patents does not reflect one. Treat any such transfer as unconfirmed pending an Assignment Center check.

NPE / troll-pattern signals

Verdict

Operating-company assertion.

Justification: the entire recorded chain is two links — an inventor-to-employer assignment dated 2004‑02‑24 to Research In Motion Limited, and a pure Change of Name (effective 2013‑07‑09, recorded 2014‑10‑24, reel 034045/0741 on the sibling record) to BlackBerry Limited, which Google Patents still lists as current assignee. No shell LLC, no known NPE/asserter ever appears in the chain, and the patent was asserted in 2018 by the original assignee's successor in its own name against actual competitors in the same messaging-device market — the classic operating-company profile, not the NPE profile. The absence of any recorded security interest, license, or third-party assignment means there is no monetization-intermediary evidence to support an NPE call, notwithstanding BlackBerry's generally aggressive licensing posture.

Carry-forward conflict from the earlier sections of this analysis: Google Patents records the patent as Active, expiry 2026‑11‑07, while PTAB IPR2019‑00925 (FWD 2020‑10‑01) held the challenged claims unpatentable and the Federal Circuit appeal (21‑1377) was voluntarily dismissed in February 2021. Ownership is unaffected by that outcome, but the assertion value of the asset is not what the "Active" status implies. Do not treat the "Active" label as confirmation the claims stand.

Verify at: https://assignmentcenter.uspto.gov/ (search 8209634; also reachable via https://assignment.uspto.gov/patent/index.html). Specifically confirm (i) the original 2004 assignment's reel/frame and correspondent, (ii) whether the 2014 change-of-name reel is in fact 034045/0741, and (iii) whether any post‑2023 Malikie Innovations assignment exists but is not yet reflected in Google Patents.

I'll research the prior art citations for US 8,209,634. Let me start with several targeted searches.

Let me look at the USPTO record and patent citation listings directly.

Let me pull the actual cited-references list for this patent from USPTO-derived sources.

Prior-Art Analysis — US 8,209,634 B2 ("Previewing a new event on a small screen device")

Search-scope note (read first). I searched for the literal identifier 8209634 and the comma-rendered form 8,209,634, constrained to this patent. I did not import results for other numbers that happen to share the digits 8209634 — notably GB 2 117 903 A (its GB priority number is 8209634), FR 8,209,634 / FR 2528055 A1 (a polyethylene-copolymer filing by BP), and US 8,209,634 B2 in forward-citation lists. Those are different documents/jurisdictions and are excluded.

Important limitation I must state up front: the authoritative Google Patents transcription supplied for this analysis contains a forward-citation panel ("Cited By (25)") and a family-citation panel ("Families Citing this family (330)"), but it does not include the patent's backward "Patent Citations / References Cited" list (the examiner-cited U.S. and foreign patent documents). My searches did not return a primary-source rendering of that front-page list. I therefore distinguish carefully below between (a) prior art I verified as cited/applied during prosecution, and (b) prior art that cannot be confirmed from the material I could retrieve. I do not fabricate citations.

1. Verified prior art cited during prosecution of US 8,209,634

These are confirmed because petitioner exhibits and prosecution-history quotations in the IPR record describe them as "cited by the Examiner during prosecution of the '634 patent."

(a) Nokia 9210i Communicator — product web page from www.nokia.com

(b) "Salmimaa" reference (Nokia)

Key takeaway on the verified prosecution art. The examiner's § 102 challenge rested essentially on Nokia Communicator (and Salmimaa) NPL, i.e., a device that displays messaging and provides new-event notification. The applicants' distinguishing arguments were (i) "small" screen and (ii) the correspondent-count limitation now in claim 1 (hence the earlier note in the Patent Summary that claim 1's numeric character counts distinct messaging correspondents, not raw messages). The examiner's cited art is best characterized as anticipating/obviousness art directed at the "visually modify an icon for a new event" concept, narrowly escaped on the small-screen and correspondent-count requirements.

2. Prior art relied on in post-grant PTAB proceedings (IPR2019‑00925, instituted — all challenged claims held unpatentable)

The instituted Facebook/Instagram/WhatsApp IPR (IPR2019‑00925, FWD Oct. 1, 2020) is the most probative prior-art event for the '634 claims, because the Board's Final Written Decision held claims 1, 4–7, 10–13, 16–18 unpatentable. Per the previously generated Litigation section, that FWD is dispositive of validity unless reversed (the Federal Circuit appeal, 21‑1377, was voluntarily dismissed in Feb. 2021).

• The petitioner's exhibit list I could see included Ex. 1014 = Nokia 9210i Communicator web page (the same examiner-cited art).
• I could not retrieve the full exhibit list or the specific § 102/§ 103 primary reference(s) the Board relied on in the FWD within this session. I therefore cannot state, with confidence, which patent or printed publication(s) the Board held anticipated the '634 claims. Do not treat any specific reference number here as verified.

⚠️ If a specific anticipation reference is required, it must be pulled from the IPR2019‑00925 Final Written Decision (Paper citing the ground) and the petition's exhibit list — neither of which was returned in retrievable form here.

3. What the "References Cited" list is not (common confusion to avoid)

The Google Patents "Cited By (25)" and "Families Citing this family (330)" panels are forward citations — later documents citing '634. They are not prior art to '634 and cannot anticipate it. Examples surfaced in the search results (all after '634):

Sources: uspto.report/patent/grant/D703,692; uspto.report/patent/grant/D763299; patents.justia.com/patent/D916866; patents.justia.com/patent/D709096.

4. § 102 mapping summary (only for verified art)

5. Explicit uncertainty flags

1. Blanket caveat: the authoritative patent text I was given does not contain the backward "References Cited" table, and my searches did not surface a primary-source rendering of it. Any complete enumeration of the '634 front-page citations therefore cannot be confirmed from the material available to me and should be verified via USPTO PatentCenter / Public PAIR (App. 10/784,781) or the patent PDF front page.
2. Salmimaa: I am confident it is a real examiner-applied reference named in the '634 prosecution history, but I do not know its full citation/number/date and have not guessed it.
3. IPR2019‑00925 primary reference(s): The Board's FWD held the challenged claims unpatentable, but I could not retrieve the specific § 102/§ 103 reference(s) on which that holding rested. Do not attribute a specific number (e.g., any particular U.S. patent) to that ground without checking the FWD and exhibit list.
4. No contradiction with prior sections: this section is consistent with the earlier Patent Summary (which already identified the examininer-cited Nokia 9210i webpage and the correspondent-count narrowing). No conflicts to flag — only the additions that the Salmimaa reference also appears in the prosecution history and that the front-page citation list itself was not retrievable here.

I'll verify the key references before building the § 103 analysis.

Let me pull details on Ording and the denied petitions' alternative art.

§ 103 Obviousness Analysis — US 8,209,634 B2

Analyst note on source reconciliation (flagging a contradiction in the record): The earlier Prior Art section of this analysis stated that the specific references underlying the IPR2019‑00925 Final Written Decision "could not be retrieved," and marked them "not verified." The earlier PTAB challenges section nonetheless supplied those references precisely. Subsequent retrieval in this session resolves the doubt in favor of the PTAB section: the instituted ground was Ording (US 7,434,177) + Abiko (US 2002/0142758 A1) + Crumlish (1996) + Dvorak (PC Magazine, Jan. 19, 1999), with McPherson (2002) added for claims 6/12/18 and Strom (Computerworld, Nov. 8, 1999) pleaded in backup grounds. I therefore treat the Prior Art section's uncertainty flag on this point as superseded (the Nokia 9210i webpage and "Salmimaa" characterizations remain valid and are used below for the prosecution-history portion). Sources: https://ai-lab.exproprio (Petition analysis, IPR2019‑00925) at https://ai-lab-cl-prod.azurewebsites.net/case/ptab/IPR2019-00925/doc/summary/2 ; Ex. 1109/1110/1111/1112 records; https://insight.rpxcorp.com/patent/[US7434177B1](/patent/US7434177B1) ; https://uspto.report/patent/grant/[7434177](/patent/7434177)

1. Governing law and temporal framework

• Statute: 35 U.S.C. § 103(a) (pre‑AIA). The '634 patent's earliest effective filing is 2003‑12‑01 (provisional 60/525,958); the non‑provisional was filed 2004‑02‑24 — both before the AIA's 2013‑03‑16 change. The pre‑AIA "person having ordinary skill in the art" (PHOSITA) standard and the Graham/KSR framework apply.
• Graham v. John Deere factors: (1) scope and content of the prior art; (2) differences between the prior art and the claims; (3) level of ordinary skill; (4) secondary considerations.
• KSR Int'l v. Teleflex (2007): a combination is obvious where the elements are known, the combination is a predictable use of prior-art elements according to their established functions, and there existed an "apparent reason" to combine — including design incentives, market forces, and "obvious to try" over a finite number of identified, predictable solutions.
• Post-grant posture (carry-forward): this is not a hypothetical. The Board actually ran this analysis and held all 12 challenged claims unpatentable (IPR2019‑00925, FWD 2020‑10‑01), and the appeal (CAFC 21‑1377) was voluntarily dismissed (mandate 2021‑02‑26). The § 103 discussion below is a reconstruction and stress‑test of those grounds, not a prediction.

2. Date-qualification of the art (a point the earlier section left as "presumed pre‑2003")

The Ording § 102(e) point matters: Ording is often mischaracterized as "post-dating" the '634 because it issued in 2008. As a pre‑AIA reference its 1999‑12‑20 filing date controls. This is the single most important date correction to carry forward.

3. Level of ordinary skill (PHOSITA)

Reconstructed from the field and the record: a PHOSITA as of 2003 would hold a bachelor's in computer science, electrical engineering, or equivalent, and 2+ years' experience in mobile/wireless device software, graphical user interfaces, and/or electronic messaging clients. The art is squarely the intersection of (a) GUI notification design and (b) wireless messaging clients — both well‑developed by 2003. Caveat: I did not retrieve the Board's verbatim PHOSITA definition from the FWD; Petitioner's expert (Chatterjee) supplied the opinions. Treat the above as a reasonable reconstruction rather than a quoted finding.

4. Claim construction inputs (from the C.D. Cal. Markman Order, Dkt. 152)

These constructions drive the § 103 analysis and are the same ones the Board applied:

• "wireless communication device" — no construction. The court found the prosecution history "ambiguous," rejected both BlackBerry's disclaimer argument and defendants' recapture theory, and noted BlackBerry had cancelled proposed claims referencing a "small display." Consequence for § 103: the claims are not limited to small-screen devices. This is decisive — it removes BlackBerry's principal non‑obviousness argument against Ording (a desktop Macintosh userbar) and against Abiko (a mobile phone).
• "messaging correspondent" — BlackBerry: "distinct sender of an electronic message to the user of the wireless communication device"; Defendants: "a person from whom messages may be received." Either way, Abiko's Figure 8 "sender address / sender name" table satisfies it.
• "icon" — BlackBerry: "picture or symbol representing a computer application or function."

5. Primary combination — the instituted ground (Grounds 1–2)

Primary references: Ording + Abiko → bridged by Crumlish (unread‑only) and motivated by Dvorak; McPherson added for the preview claims.

5.1 Element mapping — independent Claim 1

The only genuine gap is that Ording counts messages while the claim counts distinct correspondents. Abiko is the express teaching that supplies the missing element; Crumlish closes the "unread" qualifier.

5.2 Why a PHOSITA would have combined them (the KSR "apparent reason")

This is where the obviousness case is strongest, because the motivation is articulated from both references and from the state of the art:

1. Same field, overlapping problem. Both Ording and Abiko are electronic‑messaging GUI references addressing how to notify a user of received message status. Ording itself frames the userbar as consolidating "launching and managing running applications … and status and notification on running processes" (5:9–14), with e‑mail as the worked example. Abiko addresses the user's difficulty finding messages from a particular sender. → Analogous art; combination of references from the same endeavor.

2. Ording expressly invites the combination. Ording states its techniques "can be used in combination with any system having a processor and a display" (6:22–23) and that its icons can scale to 16 × 16 pixels (15:26–30). A PHOSITA seeking to implement the userbar on a mobile device (Abiko) would have had explicit textual license to do so — this defeats any "teaching away" argument premised on Ording being desktop-only.

3. Abiko supplies express motivation to count senders of new messages. Abiko ¶0011 ("the received messages used to create the menu information … may include all received messages or only received messages that satisfy prescribed conditions") and ¶0015 ("it can create the menu information … when a new message is received"). Abiko therefore itself points to sender-counting over new messages.

4. Dvorak supplies the why. Dvorak documents the e‑mail-overload problem: bulk/broadcast mail, "reply‑to‑all" misuse, no effective organization tools, and duplicate copies from the same sender. A PHOSITA reading Dvorak would recognize that a raw message count is inflated and uninformative precisely because many unread messages are duplicates from one source — and that a distinct-sender count cures that. This is the classic KSR "design incentive / market force" motivation, not a hindsight gloss: Dvorak pre-dates the '634 priority by ~5 years.

5. Predictable variation / obvious to try. Ording teaches that the overlaid number "can be updated and changed to reflect changes in the status of the in‑box, e.g., increasing as new messages are received … or decreasing after the user reviews his or her messages" (13:17–21). Counting distinct senders is a predictable variation among a small, finite set of ways to "reflect changes of the status of the in‑box." The modification is a straightforward data‑selection change in already‑existing counting logic.

6. Trivial implementation, no technical obstacle. Crumlish's "New mail folder" is a routinized storage convention; adapting Abiko's sender‑table generation to process only that folder requires no new hardware and no unpredictable programming. Both references are network‑agnostic; by 2003 wireless mail clients were commonplace (Strom, 1999).

7. No teaching away and no unexpected result. Nothing in Ording or Abiko disparages sender-centric counting or icon badging. The combination yields exactly what each reference promises — a consolidated notification location (Ording) displaying the number of message sources (Abiko).

5.3 Dependent claims 2–6 (and parallels 8–12, 14–18)

Note the internal design of the claim set: claims 6/12/18 (content preview) require McPherson; everything else is met by the four‑reference core. This is why the Board split the FWD into two grounds (Ground 1 for claims 1/4/5/7/10/11/13/16/17; Ground 2 for 6/12/18).

5.4 Independent claims 7 and 13

Claims 7 (CRM) and 13 (device: processor + display + memory) recite the identical three steps as claim 1 in different statutory categories. They rise or fall with claim 1:

• Claim 7 — Ording's badging instructions + Abiko's sender-counting logic are, collectively, the "executable instructions/data structures" stored in memory.
• Claim 13 — Abiko expressly supplies the hardware: a mobile telephone with antenna 1 and wireless unit 2 (¶¶0036–0037), a display (Fig. 10 screens), and processing. Combined with Ording's tile, all elements are present.

6. Backup / alternative combinations

• Grounds 3–4 (Strom added). Petitioner pleaded Strom ("Three New Wireless E‑Mail Devices," Computerworld, 1999‑11‑08) to pre‑empt a narrow reading of "wireless communication device." Strom corroborates that wireless e‑mail devices with on‑device notification were known. This is a contingency ground; it became unnecessary once the court declined to construe the term narrowly (Markman Dkt. 152).
• Nokia 9210i Communicator + Salmimaa. The examiner applied the Nokia 9210i webpage (and a Nokia "Salmimaa" reference) against claim 1. As the Prior Art section notes, BlackBerry escaped on (i) the "small screen" point and (ii) the correspondent-count limitation. Under the Markman ruling, the "small screen" escape collapses (no construction limiting device size), leaving only the correspondent count as the point of novelty — and that is exactly what Abiko + Crumlish + Dvorak teach. The prosecution art therefore reinforces rather than weakens the § 103 case: the very limitation BlackBerry relied on to get the patent issued is the limitation the IPR art targets.
• "Canfield." The Markman order quotes applicant's remark that "Canfield is concerned solely with desktop‑type large screen devices … [and] teaches away." I could not retrieve Canfield's full citation, date, or content and therefore do not rely on it in any ground. Flagged as an unresolved item; if verified, Canfield is a further candidate reference.
• Denied petitions (IPR2019‑00924, IPR2019‑00939). These were filed on different art and institution was denied on the merits. I could not retrieve the specific references or the Board's reasoning, so I cannot present them as an alternative ground. Their existence is itself probative only in that the Board found the alternative art insufficient while instituting on Ording/Abiko/Dvorak — i.e., the Ording combination is the proven theory.

7. Anticipated counter-arguments and why they likely fail (or where they have traction)

Genuine open issues (to be candid): (a) the exact (verbatim) PHOSITA definition the Board adopted is unretrieved; (b) I could not obtain the FWD text to confirm that the Board relied on the same passages for claim 1[c] as the petition; (c) the McPherson content‑preview mapping for claims 6/12/18 is reconstructed from the petition summary, not the FWD; (d) the "Salmimaa" and "Canfield" citations remain unverified.

8. Secondary considerations

None of record. I found no Patent Owner Response or district-court submission in the retrieved materials asserting objective indicia (unexpected results, long‑felt need, industry praise, licensing‑driven nexus, copying) tied to the correspondent-count limitation. Where no nexus‑bearing evidence is offered, secondary considerations cannot rebut a strong prima facie § 103 case. Caveat: BlackBerry's commercial success with BlackBerry handhelds is well documented, but commercial success of a device that practices a broad prior art combination does not establish nexus to the specific claim limitation; and the district court's § 101 ruling and the FWD both cut against a nexus narrative.

9. Bottom line

Combination 1 (the operative ground):
Ording (US 7,434,177) + Abiko (US 2002/0142758 A1) + Crumlish (1996) + Dvorak (1999) renders claims 1, 4, 5, 7, 10, 11, 13, 16, 17 obvious under pre‑AIA § 103(a) — Ording for the badged messaging icon and the icon‑invokes‑application structure; Abiko for multiple messages from distinct correspondents and the sender‑counting (and sender‑identifying) logic; Crumlish for unread‑only filtering; Dvorak for the motivation that a distinct‑sender count is more informative than a raw count.

Combination 2: the same combination + McPherson (2002) renders claims 6, 12, 18 obvious (content preview).

Never-challenged claims 2, 3, 8, 9, 14, 15: these add only Ording's own disclosures (a plurality of userbar tiles, and an overlaid count of unread messages that increases/decreases with inbox state). They are not a refuge — they are obvious over Ording alone in view of Abiko, and in any event they depend from independent claims 1, 7, and 13, which the Board held unpatentable.

Net: the primary reference combination maps every limitation of the independent claims, the proffered motivation is documented in the references themselves (Ording's express invitation + Abiko's express "prescribed conditions"/"new message" teachings + Dvorak's stated problem), the modification is a predictable data‑selection change with no new hardware and no asserted unexpected result, and the Board's actual FWD cancelling all 12 challenged claims is the ground truth. The '634 claims are obvious under § 103.

10. Carry-forward flags (do not lose these)

1. Source contradiction resolved in favor of the PTAB section — the Prior Art section's "IPR references could not be retrieved" is superseded; the references are Ording/Abiko/Crumlish/Dvorak/Strom/McPherson.
2. Ording date correction: it is § 102(e) art as of its 1999‑12‑20 U.S. filing date, notwithstanding its 2008 issue date. Do not treat it as post-dating the '634.
3. Status conflict stands: Google Patents shows "Active, expires 2026‑11‑07" while the FWD cancelled the challenged claims and the appeal was voluntarily dismissed. Ownership (BlackBerry Limited) is unaffected; assertion value is not what "Active" implies.
4. Claim text governs over secondary sources: claim 1 counts distinct messaging correspondents, not raw unread messages (see Patent Summary §3 and flag #4). Any § 103 chart must use the correspondent-count language.
5. Family caveat: the same Ording/Abiko/Crumlish/Dvorak combination has not (on the retrieved record) been adjudicated against US 8,631,353, US 9,830,045, or US 11,740,763; those continuation claims require their own mapping, particularly where they recite preview, state, or "jump‑to‑message" features (the FIG. 6–8 embodiments) that may need McPherson or additional art.
6. Unverified items: "Salmimaa" and "Canfield" full citations; the Board's verbatim PHOSITA definition; the IPR2019‑00924/‑00939 reference lists and the text of the two denials.
