US 9049188

I'll search for authoritative information on this patent number across USPTO and litigation sources.

Let me retrieve the exact claim text and check litigation/docket status specifically for the '188 patent.

Let me verify the current claim language and any reexamination/litigation status specific to the '188 patent.

US 9,049,188 B1 — Analyst Summary

Search method note: I could not query PACER or the USPTO PatentCenter/PTAB APIs directly; the findings below come from web searches surfacing the Google Patents full text (which you supplied and which I treat as authoritative for the specification), the USPTO patent PDF as filed into PTAB exhibits, Unified Patents' patent/case portal, Docket Alarm PTAB dockets, and one trade-press report (ip fray). Where sources disagree on a date I flag it.

1. Bibliographic data

Continuation family (same specification): 12/329,329 → US 8,171,528; 13/445,825 → US 8,646,042; 14/171,705 → US 9,049,188; 14/677,893 → US 9,235,700; 14/961,645 → US 9,679,289; 15/595,739 → US 10,073,960; 16/048,044 → US 11,080,378. A terminal disclaimer in the '289 prosecution disclaimed term beyond the '700 and '188 patents, so these are patentably-related continuations.

Minor source discrepancies: Unified Patents' portal lists the "Application Date" as 2014-02-02 and "Grant Date" as 2015-06-01, and the "Priority Date" as 2007-12-05, whereas the patent front page and Google Patents show Feb. 3, 2014 / June 2, 2015 / Dec. 6, 2007. The patent document controls.

2. Abstract (verbatim)

"A hybrid device includes a personal digital key (PDK) and a receiver-decoder circuit (RDC). The PDK and RDC of the hybrid device are coupled for communication with each other. In one embodiment, the hybrid device also provides a physical interconnect for connecting to other devices to send and receive control signals and data, and receive power. The hybrid device operates in one of several modes including, PDK only, RDC only, or PDK and RDC. This allows a variety of system configurations for mixed operation including: PDK/RDC, RDC/RDC or PDK/PDK. The present invention also includes a number of system configurations for use of the hybrid device including: use of the hybrid device in a cell phone; simultaneous use of the PDK and the RDC functionality of hybrid device; use of multiple links of hybrid device to generate an authorization signal, use of multiple PDK links to the hybrid device to generate an authorization signal; and use of the hybrid device for authorization inheritance."

3. Independent claims — plain language

Rosetta-stone vocabulary used below: PDK = a portable, tamper-resistant "personal digital key" that stores a user's secured data and talks wirelessly to a reader; RDC = "receiver-decoder circuit," the reader/sensor half that wirelessly reads (and decodes encrypted data from) a PDK within a short-range proximity zone; hybrid device = a single device that contains both halves.

Claim 1 (apparatus) — "one device that is both the key and the lock"

A hybrid device has two integrated parts:

1. An integrated PDK — stores local, secured biometric information for authenticating a user, and can talk wirelessly to an RDC that is outside the device; and
2. An integrated RDC — can talk wirelessly to at least one external PDK inside its proximity zone.
3. The two integrated parts are wired together internally (coupled by a "first signal line" for communication), which is the point that distinguishes this from two separate pieces of hardware in the same pocket.
4. The integrated RDC is also wired (a "second signal line") to at least one other component of the hybrid device (e.g., a processor, memory, biometric reader or power source).
5. The integrated RDC and/or integrated PDK enable an application, a function, or a service (i.e., acting as both sides of the secure transaction).

Practical reading: a single piece of hardware (the spec's lead example is a SIM-card-form-factor part dropped into a cell phone) that can simultaneously present itself as a credential-bearing key to someone else's reader and serve as a reader for someone else's key.

Claim 10 (method) — "establish a link, receive a signal, enable the service"

A method that:

1. Creates a first wireless link between the integrated RDC of a hybrid device and an external PDK — where the hybrid device also contains an integrated PDK that stores local, secured biometric information for authenticating a user;
2. Receives a first signal at the integrated RDC over that wireless link from the external PDK; and
3. Generates an enablement signal that enables an application, a function, or a service.

Practical reading: the operational counterpart of claim 1 — a device that doubles as a reader establishes a link to a nearby key, takes in the key's signal, and then outputs an "enable" signal (the spec's examples include unlocking a PC, unlocking a safe-deposit box, or enabling a cellular service).

Claim set structure: claims 1–9 depend from apparatus claim 1; claims 10–20 depend from method claim 10 (the Apple petition's grounds map claim 8 to claim 1 and claims 16, 19 and 20 to claim 10, which confirms two independent claims). Dependent-claim subject matter cited in the record includes PDK form factors such as jewelry/watches (claims 8 and 20 territory).

Uncertainty flag on exact claim wording: The verbatim claim-1 text I could ground is from the RPX/Insight and PTAB-derived excerpts, which read "…an integrated personal digital key (PDK) for storing local, secured biometric information for authenticating a user…," consistent with Apple's petition characterization. One PTAB-style excerpt I encountered appended a longer tail to the enablement clause ("…enabling one or more of an application, a function, and a service on one or more of the hybrid device and a device associated with the external RDC"), but that excerpt came from a multi-patent PTAB document and I could not confirm it belongs to the '188 rather than a sibling ('042/'700) claim. The sibling US 9,679,289 claim 1 instead recites an "integrated, secure memory storing local, secured information" (no "biometric" and no "PDK" label), and US 9,235,700 claim 1 recites "local, secured financial information" — so cross-family claim language must not be mixed. If you need the exact, currently-in-force claim text, pull the '188 patent PDF claim column (21:xx–23:xx) or the PatentCenter "Claims" tab; I could not verify whether any ex parte reexamination certificate has amended the '188 claims.

4. Enforcement / PTAB / CAFC status (as surfaced by search)

PTAB — this specific patent (9,049,188):

• IPR2021-01438 — [Samsung Electronics America, Inc.](/litigations/by-plaintiff/Samsung%20Electronics%20America%2C%20Inc.) v. Proxense, LLC, patent 9,049,188. Instituted; oral hearing held Nov. 29, 2022 (the same panel heard IPR2021-01439 on US 9,235,700). Google Patents now lists this case as "filed (Settlement)" — i.e., resolved rather than decided on the merits, consistent with the district-court consent judgment below. (Note: Google's own annotation mentions Unified Patents as the data source for the case link; the petitioner of record in the Board transcript is Samsung.)
• IPR2025-00562 — Apple Inc. v. Proxense, LLC, patent 9,049,188. Filed Feb. 7, 2025; Trial Instituted; still pending. Docket Alarm shows a Petitioner Reply with supplemental Wolfe declaration on March 23, 2026, and Patent Owner's Response on Dec. 29, 2025. Grounds per the public petition summary: (1) claims 1–20 obvious over Giobbi '157 in view of Giobbi '139 and Dua; (2) claims 1–7, 9–15, 17–18 obvious over Broadcom EP 1,536,306 A1; (3) claims 8, 16, 19–20 obvious over Broadcom in view of Giobbi '157. A Final Written Decision would be expected roughly within a year of institution (i.e., likely late 2026), so no FWD on the '188 was identified as of this search.

District court (the '188 is a Patents-in-Suit in at least two campaigns):

• Proxense, LLC v. [Samsung Electronics Co., Ltd. et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.), No. 6:21-cv-00210 (W.D. Tex., Judge Alan Albright) — asserted patents included US 9,049,188 B1, US 8,352,730, US 10,698,989, US 9,235,700 and US 9,298,905. Terminated Jan. 19, 2023 by stipulated dismissal with prejudice / consent judgment, each side bearing its own costs; no merits ruling on infringement or validity.
• Proxense, LLC v. Apple Inc., No. 6:24-cv-00143-ADA (W.D. Tex.) — Proxense's infringement contentions assert the '188 (Exhibit E chart) among the asserted Proxense patents; Apple's counter-challenge is the pending IPR2025-00562. Trade press reports this litigation (and the Microsoft case) as stayed as of April 2026.

CAFC 2026 dockets: I found no Federal Circuit appeal docket specifically naming US 9,049,188 in 2026. The 2026 Proxense Federal Circuit activity reported by ip fray is Proxense's opening brief in consolidated appeals from IPR2024-00233, IPR2024-01334 and IPR2024-00846, which concern U.S. Patent No. 8,886,954 ("Biometric personal data key (PDK) authentication") — a different patent, not the '188. Do not treat that appeal as an appeal of the '188.

5. Confidence and caveats

• High confidence: title, patent number, application number, inventor, assignee, issue date, abstract, 20 claims/15 sheets, priority chain, and the identity of the independent claims (1 and 10) as grounded in the Google Patents full text you supplied plus the USPTO front page reproduced in PTAB Exhibit 1011.
• Medium confidence: the exact verbatim wording of claim 1 and claim 10 as currently in force — I reconstructed these from secondary claim-text repositories and PTAB quotations rather than a direct fetch of the printed claim column, and I could not confirm whether a reexamination certificate has amended them. Note also that Proxense has amended claims in related patents (e.g., EPR 90/015,052 on the '730 patent), so claim text across the family should not be assumed static.
• Medium confidence: the litigation/PTAB posture. IPR2025-00562 (Apple, pending/instituted) and IPR2021-01438 (Samsung, terminated) are well supported; the "settlement" characterization of IPR2021-01438 rests on Google Patents' case annotation rather than a Board order text.
• Not established: any reexamination certificate for the '188; any 2026 CAFC appeal naming the '188; any merits ruling on the validity or infringement of the '188.
• Naming caution per your instructions: one search hit was for the Japanese publication JP 9049188 A (a Japan Tobacco/Mishima Paper document cited in an unrelated PCT search report) — that is not US 9,049,188 and should not be conflated with it.

I'll research litigation involving US Patent 9049188. Let me run several searches.

Let me dig into the specific cases identified.

Litigation involving U.S. Patent No. 9,049,188

Important framing note: For this exercise I treated the patent as literally US 9,049,188 B1 ("Hybrid device having a personal digital key and receiver-decoder circuit and methods of use," Proxense, LLC; app. 14/171,705; filed 2014‑02‑03; granted 2015‑06‑02). I disregarded unrelated hits for other numbers (e.g., JP 9049188 A, US 10,092,918, Netlist's "’918", US 9,042,819). The records below all expressly identify 9,049,188 B1 as a patent‑in‑suit.

I found two federal district court cases and two PTAB (IPR) proceedings in which US 9,049,188 is directly implicated. All involve Proxense, LLC as patent owner/plaintiff (or patent owner in the IPRs).

1. Proxense, LLC v. [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) and Samsung Electronics America, Inc.

• Plaintiff: Proxense, LLC
• Defendants: Samsung Electronics Co., Ltd.; Samsung Electronics America, Inc.
• Jurisdiction/Court: U.S. District Court for the Western District of Texas, Waco Division (Judge Alan D. Albright)
• Case No.: 6:21‑cv‑00210‑ADA
• Filing date: March 5, 2021
• Patents asserted: US 8,352,730; US 10,698,989; US 9,049,188; US 9,235,700; US 9,298,905 (accused products: Samsung Pay / Galaxy devices)
• Outcome / status: Resolved before trial. The docket reflects a consent judgment / stipulated dismissal with prejudice under Fed. R. Civ. P. 41(a)(1)(ii), each party bearing its own fees, expenses, and costs; the case closed January 19, 2023. No court ruling on validity or infringement of the ’188 was issued. (Jury selection had been cancelled days before trial; by then the case concerned only two patents.)

2. Proxense, LLC v. Apple, Inc.

• Plaintiff: Proxense, LLC
• Defendant: Apple, Inc.
• Jurisdiction/Court: U.S. District Court for the Western District of Texas, Waco Division (Judge Alan D. Albright)
• Case No.: 6:24‑cv‑00143‑ADA
• Filing date: March 18, 2024
• Patents asserted: US 9,298,905; US 8,352,730; US 8,886,954; US 10,698,989; US 9,049,188; US 8,646,042
• Outcome / status (as to the ’188): In a joint motion to amend the scheduling order filed September 26, 2024, the parties stated that Proxense intended to dismiss with prejudice all allegations that Apple infringes U.S. Patent No. 9,049,188, and to substitute U.S. Patent No. 9,679,289 (same family). The case otherwise remained pending, with a jury trial originally set for January 19, 2026 under the amended scheduling order. I could not confirm the post‑January‑2026 status of the overall Apple case from the records retrieved.

Tex. docket (https://dockets.justia.com/docket/texas/txwdce/6:2024cv00143/1172779468); joint motion / amended scheduling order, Case 6:24‑cv‑00143‑ADA, Doc. 38 (Sept. 26, 2024); RPX Insight (https://insight.rpxcorp.com/litigation/txwdce-1172779468-proxense-v-apple).

PTAB proceedings (inter partes review) — not "litigation" per se, but directly on this patent

3. Samsung Electronics America, Inc. v. Proxense, LLC — IPR2021‑01438

• Petitioner: Samsung Electronics America, Inc. (Quinn Emanuel)
• Patent Owner: Proxense, LLC (Hecht Partners)
• Patent challenged: US 9,049,188 B1 (consolidated for hearing with IPR2021‑01439 on US 9,235,700)
• Filing date: 2021
• Status: Oral hearing held November 29, 2022; Google Patents lists the proceeding as filed (Settlement) — i.e., terminated without a final written decision on validity.
• Sources: PTAB oral hearing transcript (docketalarm.com, IPR2021‑01438/‑01439, Nov. 29, 2022); Google Patents litigation entry for US 9,049,188.

4. Apple Inc. v. Proxense, LLC — IPR2025‑00562

• Petitioner: Apple Inc.
• Patent Owner: Proxense, LLC
• Patent challenged: US 9,049,188 B1 (claims 1–20)
• Filing date: February 7, 2025
• Grounds (as pleaded): Obviousness over Giobbi ’157 in view of Giobbi ’139 and Dua; over Broadcom (EP 1536306 A1); and Broadcom in view of Giobbi ’157; etc.
• Status: Instituted and pending. A Petitioner Reply to Patent Owner’s Response (with exhibits) was filed March 23, 2026, so the trial was still active as of April 2026.
• Sources: Docket Alarm, IPR2025‑00562 (https://www.docketalarm.com/cases/PTAB/IPR2025-00562/Apple_Inc._v._Proxense_LLC/); petition summary at ai‑lab.exparte.com (IPR2025‑00562, doc. 2); Google Patents litigation entry.

Negative / cautionary findings

• No other district court or ITC cases identifying US 9,049,188 were found. Google Patents' family-litigation listing for US 9,049,188 shows only the two W.D. Tex. cases above plus the two PTAB matters, and a generic "first worldwide family litigation" link (family 45990985).
• Proxense's other 2023–2024 suits — Proxense v. Google, No. 6:23‑cv‑00320 (W.D. Tex.), and Proxense v. Microsoft, No. 6:23‑cv‑00319 (W.D. Tex.) — appear in the same campaign but I found no record of the ’188 being asserted in those two cases (they involved the ’730/’905/’989/’042 families). Likewise Proxense v. Intel, No. 6:24‑cv‑00283, lists different patents (e.g., ’152/’129/’730/’672/’043). Treat this as "not identified" rather than a definitive negative.
• No CAFC appeal of an ’188 merits decision is known; the Samsung IPR is recorded as settled rather than appealed.
• I could not verify whether any financial/licensing terms underlay the Samsung resolution (undisclosed in the public record), nor the exact current (post‑April 2026) disposition of the Apple case.

Bottom line: Publicly recorded activity on US 9,049,188 consists of (a) Proxense v. Samsung (6:21‑cv‑00210‑ADA), ended by consent judgment/dismissal with prejudice in January 2023; (b) Proxense v. Apple (6:24‑cv‑00143‑ADA), in which the ’188 allegations were dismissed with prejudice in late 2024 and replaced by the ’289 patent; (c) Samsung's IPR2021‑01438, settled; and (d) Apple's IPR2025‑00562, instituted and still pending.

I'll research the PTAB proceedings identified on the patent's face (the Google Patents family-litigation block lists IPR2021-01438 and IPR2025-00562) plus any others.

Now let me pin down the outcomes of both proceedings.

Let me confirm the institution dates, the panel, and whether the June 2025 FWD concerns this patent.

PTAB proceedings on US 9,049,188 B1 ("Hybrid device having a personal digital key and receiver-decoder circuit and methods of use")

Data-integrity flag up front: the structured "PTAB proceedings on file" block in this prompt reports that the USPTO ODP API returns no AIA trial proceedings for this patent. That is inconsistent with the patent's own front-matter litigation data, which lists two PTAB cases, and with the public dockets. I am therefore sourcing the list from the patent's front-matter block (Google Patents, fetched 2026-09-18) plus Docket Alarm/PTAB records, and flagging the ODP omission. Do not treat the ODP "no proceedings" result as authoritative here.

Proceedings overview

There are two AIA trial proceedings on the '188 patent (both Inter Partes Review; no PGR, no CBM): one live and instituted (IPR2025-00562, Apple) and one terminated by settlement after institution, with no Final Written Decision (IPR2021-01438, Samsung). Status breakdown: active/instituted 1; settled 1; claims invalidated 0; claims sustained 0; institution denied 0. Bottom line for a defendant: this patent has never been adjudicated on the merits at the PTAB and not one of claims 1–20 has been canceled — so a demand letter citing any claim is not presently "sanction-bait," and the patent still carries its full presumption of validity. But the file is not benign: the Board has twice instituted IPR on this claim set over essentially the same Giobbi/Broadcom art, and the Apple trial's statutory FWD deadline lands in early October 2026 — within weeks of today (2026-09-18).

IPR2025-00562 — Apple Inc. v. Proxense, LLC

• Type: Inter Partes Review (35 U.S.C. §§ 311–319)
• Filed: 2025-02-07
• Status: "Pending - Instituted" (verbatim from the patent's front-matter PTAB block); Docket Alarm renders the same status as "Trial Instituted." Live trial, Tech Center 2400 / Art Unit 2438.
• Judge panel: Not public in the sources I was able to retrieve. A "Notice: Referral to Board Panel" was docketed 2025-06-17, but no APJ names were surfaced. I cannot name the panel — do not assume it is the Samsung panel.
• Petition grounds (as summarized in the petition record):
  • Ground 1 — Claims 1-20 obvious under § 103 over Giobbi '157 (US 2007/0245157 A1) in view of Giobbi '139 (US 2004/0255139 A1) and Dua (US 9,042,819).
  • Ground 2 — Claims 1-7, 9-15, and 17-18 obvious over Broadcom (EP 1 536 306 A1) standing alone.
  • Ground 3 — Claims 8, 16, and 19-20 obvious over Broadcom in view of Giobbi '157 (these are the claims requiring the external PDK to be embodied in jewelry or a watch).
  • Petitioner's expert: Andrew Wolfe, Ph.D. (Ex. 1003; supplemental declaration Ex. 1013 filed 2026-03-23).
• Institution decision: Instituted. I could not retrieve the Decision Instituting itself, but the record places institution on or immediately before 2025-10-02, when the Board entered its Scheduling Order. That timing is consistent with the docket arithmetic: Notice of Filing Date Accorded 2025-04-11 → POPR due 2025-07-11 (PO filed 2025-07-11) → § 314(b) three-month institution deadline ≈ 2025-10-11. Proxense's POPR requested discretionary denial under § 314(a) (Ex. 2001 = Claim Construction Order), so institution necessarily rejected that request. The panel's stated reasoning is not in the record I retrieved; I am not characterizing it.
• Final Written Decision: None issued. The most recent docket entry retrieved is Petitioner's Reply to Patent Owner's Response, 2026-03-23; no FWD appears. Patent Owner's Response was filed 2025-12-29. Since no FWD has issued, no claim of the '188 has been canceled or sustained in this proceeding, and I will not state otherwise.
• Settlement / termination: None. The proceeding is live and contested.
• Appeal: None yet (no FWD to appeal; any appeal lies to the Federal Circuit under 35 U.S.C. § 319 within 63 days of the FWD).
• Defensive value: This is the proceeding that matters today. Apple has put the entire claim set (1-20) at risk on art that is not novel to this patent — the Broadcom reference (EP 1 536 306 A1) is the same reference Petitioner Samsung relied on in IPR2021-01438 (per Petitioner's on-the-record statement at the 2022-11-29 consolidated hearing), and the Board has already once instituted on that theory. If the FWD cancels claims 1-20, the '188 is effectively dead for any defendant; if it sustains them, they come out tested and hardened. Note that Apple's petition record imports Proxense's W.D. Tex. infringement contentions against Apple (served 2025-03-04 in 6:24-cv-00143) — so the '188 is being actively asserted on the smartphone side.

IPR2021-01438 — Samsung Electronics America, Inc. v. Proxense, LLC

• Type: Inter Partes Review; consolidated for hearing with IPR2021-01439 (US 9,235,700 B1, a sibling patent).
• Filed: 2021-08-26
• Status: "Settlement" (verbatim from the patent's front-matter block, which captions it "IPR2021-01438 filed (Settlement)"); Docket Alarm's verbatim status is "Terminated-Settled", terminated 2023-02-24. Plain English: instituted, tried, argued, then killed by settlement before any FWD.
• Judge panel: Thu D. Dang (lead), Kevin F. Turner, and David C. McKone, Administrative Patent Judges (per the consolidated oral hearing transcript). Docket Alarm's case metadata additionally lists Justin Arbes as a judge on the file.
• Petition grounds: I could not retrieve the petition, so I will not state the statutory basis, art, or challenged claim set as fact. What the public record shows: at the 2022-11-29 consolidated oral hearing, Petitioner framed the case as § 103 obviousness over "the Giobbi references and Broadcom," and represented that Patent Owner's only responsive arguments were grounded in claim construction. The claims at issue were '188 claims (the patent carries claims 1-20, as reflected in Apple's later petition). Treat the exact grounds and claim scope as unverified.
• Institution decision: Instituted. The termination decision is captioned verbatim "TERMINATION Due to Settlement After Institution of Trial — 35 U.S.C. § 317; 37 C.F.R. § 42.71, 42.74." At the oral hearing, Petitioner stated on the record that the Board adopted a claim construction at institution and "reiterated [it] in the rehearing decision," and that under that construction "there's no dispute that those — under those constructions, the claims are unpatentable." The exact institution date is not in the material I retrieved; Patent Owner's 2022-12-29 filing said "approximately two months remain before the one-year deadline for completing trial," which places institution in approximately late February 2022 (inferred, not verified). The stated reasoning of the institution decision itself is not in the record I retrieved.
• Final Written Decision: None. No FWD ever issued. Because the proceeding terminated under § 317 before a final written decision, the Board never entered a merits judgment — no claim was canceled, and none was confirmed.
• Settlement / termination: On 2023-01-23 (with Board authorization) the parties filed a Joint Motion to Terminate each of IPR2021-01438 and -01439 under 35 U.S.C. § 317, attaching a confidential "Binding Term Sheet for Settlement and Patent License between Samsung and Proxense" (Ex. 2013). Because the Term Sheet said the parties "will enter into Definitive Agreements within twenty (20) days," the Board emailed the parties on 2023-02-22 demanding confirmation that the Term Sheet "fully" resolved the matter and, if a definitive agreement had been signed, its submission under § 317(b). On 2023-02-23 the parties filed a Joint Notice attaching the confidential "Settlement and License Agreement" (Ex. 2014). The Board granted termination on 2023-02-24. Both documents were filed as business confidential and kept separate under § 317(b) / 37 C.F.R. § 42.74(c) — the license terms are confidential and not in the public record. The parallel W.D. Tex. action, Proxense, LLC v. Samsung Electronics Co., Ltd., No. 6:21-cv-00210-ADA, ended 2023-01-19 on a stipulated dismissal with prejudice (recorded basis: consent judgment), each party bearing its own costs, with no merits ruling on validity or infringement of any of the five asserted patents.
• Appeal: None. A § 317 termination is not an appealable final written decision.
• Defensive value: A settlement without an FWD means zero issue-preclusion and zero statutory estoppel — Samsung's win/loss is unknowable and unusable. Nothing in this proceeding cancels, narrows, or binds a subsequent defendant. What it does give a defendant is a roadmap: the Board instituted over Giobbi/Broadcom art, adopted a construction under which the claims were (per Petitioner) undisputedly unpatentable, and denied Proxense's rehearing request — and then Proxense settled the case, the parallel district suit, and took a patent license, rather than let the construction be fixed in a final decision. Procedural note: Patent Owner made a failed collateral-estoppel play on 2022-12-29, asking to submit the W.D. Tex. claim-construction order and arguing B & B Hardware / Papst precluded Petitioner from a contrary construction after the Markman order issued 2022-12-28.

Strategic summary

Claim status. Across both proceedings: CANCELED — none. SUSTAINED — none. UNTESTED — all of claims 1-20. The '188 has been through institution twice but has never reached a Final Written Decision, so no claim has ever been adjudicated on the merits by the PTAB. The only substantive PTAB position ever taken was the Board's institution-stage claim construction (later "reiterated" on rehearing, per Petitioner's hearing statement), which was never converted into a final judgment because the parties settled. Practically, the surviving claim set for enforcement purposes is the full issued set, claims 1-20, at least until the Apple FWD issues.

Estoppel landscape. § 315(e)(2) estoppel is petitioner-specific and attaches only after a final written decision on that petitioner's grounds. Consequently:

• Samsung is not estopped — its IPR terminated by settlement under § 317 with no FWD, and the Samsung district case ended in a stipulated dismissal with prejudice plus a confidential license. Whatever Samsung bargained for is private; it does not run to third parties.
• Apple is not yet estopped, but if an FWD issues in IPR2025-00562, Apple and its real parties in interest/privies will be barred in the W.D. Tex. action (6:24-cv-00143) from raising any ground it raised or reasonably could have raised.
• For a new defendant, essentially the entire prior-art space is open: Giobbi '157, Giobbi '139, Dua (US 9,042,819), Broadcom (EP 1 536 306 A1), and anything else, by § 102 or § 103. You are not bound by anyone else's IPR. The two real constraints on a new petition are (i) the § 315(b) one-year bar from service of your infringement complaint, and (ii) the Board's § 314(a)/General Plastic discretion to deny follow-on petitions — though the fact that the Board twice instituted on the Giobbi/Broadcom theory on this very claim set is meaningful evidence that a well-pled petition here is institution-worthy.

Pattern signals. Petitioner behavior: two different defendants, same art family. Samsung filed five IPRs against five Proxense patents in 2021 (IPR2021-01438 ['188], -01439 ['700], -01444, -01447 ['905], -01448); contemporaneous reporting states the Board instituted on only two (the '188 and '700) and denied three. The Samsung dispute then collapsed into a consent judgment (2023-01-19) and a confidential settlement/license in both instituted IPRs (2023-02-24). Patent-owner behavior: Proxense litigates hard and settles late — Hecht Partners argued the PTAB cases, Proxense pushed collateral-estoppel and rehearing motions, and it chose settlement on the eve of the FWD rather than a merits ruling. Enforcement pattern: the '188 has been asserted in W.D. Tex. against Samsung (2021), Google and Microsoft (2023 filings), and Apple (6:24-cv-00143); Apple's own IPR exhibits import Proxense's infringement contentions and claim-construction positions from each of those cases. No defensive aggregator (e.g., Unified Patents) is a petitioner — Unified's portal merely indexes the patent and its cases; the ODP omission noted above does not reflect a Unified filing. Family-level caution: a 2025-06-18 FWD in an Apple IPR invalidated claims of a different Proxense patent in the biometric-verification family. I could not confirm which patent number that FWD concerns; it does not appear to be the '188, and I am not treating it as a decision on this patent.

Recommended next steps

1. Pull the Apple FWD the moment it drops — it is due within weeks. Institution fell on or about 2025-10-02, so the § 316(a)(11) one-year trial deadline is on or about 2026-10-02 (extendable up to six months for good cause). Today is 2026-09-18. Retrieve it from PTAB E2E (https://ptacts.uspto.gov/ptacts/) or the PTAB Decisions page (https://www.uspto.gov/ptab); the case docket is mirrored at https://www.docketalarm.com/cases/PTAB/IPR2025-00562/Apple_Inc._v._Proxense_LLC/. Expect a summer-2026 oral hearing before the FWD. Do not build a defense on a prediction of the outcome — wait for the paper.
2. If the FWD cancels claims 1-20 (or any subset): cite the FWD's disposition verbatim and quote the canceled claim numbers exactly. Cancellation is in rem as to the canceled claims — it binds everyone, not just Apple — and it will likely force Proxense to appeal to the Federal Circuit (63 days, § 319), which stays nothing about the cancellation's effect on other defendants in the interim. If you are a co-pending W.D. Tex. defendant, move promptly to stay or dismiss claims that no longer exist.
3. If the FWD sustains the claims: the patent emerges hardened, and Apple becomes estopped under § 315(e)(2). Pivot the defense away from validity to non-infringement under the district court's constructions — note that in Proxense v. Samsung the W.D. Tex. court adopted Proxense's proposed constructions for "PDK," "RDC," "hybrid device," "inheritance information," and "enablement signal" (including construing "enabled" to require receipt of information from a PDK in exchange for an access key). Those constructions cut against broad infringement theories.
4. On Samsung, do not rely on anything. There is no FWD, no estoppel, and the settlement and license agreement are confidential and unavailable. For the record, the operative disposition text is the Board's: "TERMINATION Due to Settlement After Institution of Trial — 35 U.S.C. § 317; 37 C.F.R. § 42.71, 42.74" (2023-02-24), available at https://www.docketalarm.com/cases/PTAB/IPR2021-01439/SAMSUNG_ELECTRONICS_AMERICA_INC_v._Proxense_LLC/docs/02-24-2023-Board/Termination_Decision__Post_DI_Settlement-31-Termination_Decision__Post_DI_Settlement.pdf, with the consolidated hearing transcript at https://www.docketalarm.com/cases/PTAB/IPR2021-01439/SAMSUNG_ELECTRONICS_AMERICA_INC_v._Proxense_LLC/docs/12-14-2022-Board/Other__Hearing_transcript-25-Other__Hearing_transcript.pdf.
5. Watch your § 315(b) clock. If you have been served with a complaint asserting the '188, you have one year to file — and given that an Apple FWD is imminent, consider whether to file a copycat/joinder petition (with a § 315(e)(2) stipulation, as Apple did in its other Proxense matters) to preserve the art while avoiding § 314(a) discretion risk.

Verification note: item-level facts above (filing dates, panel, grounds, settlement mechanics, termination text) are drawn from the patent's front-matter PTAB/litigation block, the Board's termination decision and hearing transcript in IPR2021-01438/-01439, and the Docket Alarm dockets for IPR2021-01438 and IPR2025-00562. Three items are explicitly unverified and should be confirmed against primary PTAB records before use: (a) the exact petition grounds and challenged claims in IPR2021-01438; (b) the exact institution date in IPR2021-01438; and (c) the APJ panel and institution reasoning in IPR2025-00562. The structured ODP block's "no proceedings" result is contradicted by the patent's own front matter and should be treated as an ingest gap, not a finding.

I'll research this patent's ownership chain and litigation history before assembling the record.

Let me dig into the assignment records specifically and Proxense's corporate status.

Let me try to pin down the specific reel/frame records and any Proxense corporate events.

Source limitation disclosed up front. I could reach Google Patents legal events, the PTAB dockets, the litigation record, and third‑party NPE registers, but I could not retrieve the raw USPTO Assignment Center abstract‑of‑title page (reel/frame, execution date, and correspondent of record) for this patent — the search tooling returned secondary aggregations rather than the Assignment Center record itself. I therefore report only the one assignment that is affirmatively documented, and I explicitly mark the reel/frame, execution date, and assignment correspondent as not captured rather than reconstructing them. Verify against https://assignmentcenter.uspto.gov/ by searching Patent Number 9049188.

Inventors

Observations and flags:

• The '188 patent names only Brown, even though the underlying 2007 provisional ("Reverse Prox," 60/992,953) named David L. Brown, John J. Giobbi, and Fred S. Hirt, and the sibling/parent patents (e.g., 8,171,528; 8,646,042; 9,235,700; 11,080,378) list the Giobbi/Brown/Hirt trio. This is a deliberate claim‑drafting choice on the continuation chain, not an inventor‑departure event.
• No inventor‑departure pattern detected. Brown is still the named inventor on later Proxense filings in this family (e.g., US 11,080,378, filed 2018‑07‑27), so there is no evidence of inventors leaving the assignee within 12 months of filing that would presage a fire‑sale.
• Name‑collision caution: a "Brown, David L." also appears as an inventor on KLA Corporation / KLA‑Tencor image‑sensor and detector patents (2020‑2025). There is no evidence this is the same individual; do not conflate the two.
• Fixture across the family: John J. Giobbi is Proxense's founder/CEO and is described in Proxense's own pleadings as a named inventor on ~200 patents. He is the portfolio's controlling personality even though he is not an inventor on the '188 patent.

Original assignee

Proxense, LLC — originally of Bend, Oregon; current principal place of business stated in PTAB filings as 689 NW Stonepine Drive, Bend, Oregon 97703.

• Primary line of business (historically): proximity‑based authentication, "Personal Digital Key" (PDK) technology, biometric mobile‑payment/wireless‑wallet platforms ("ProxPay"). Proxense's own filings state it was founded 2001 (Microsoft complaint ¶34) — a 2016 outreach letter from counsel says 2005 — and that it developed and commercialized secure‑element/biometric/mobile‑payment technology from ~2004–2012 with 30+ engineers.
• Did they ship a product embodying the claims? Not documented for this patent. Proxense refers to "commercial products" and media coverage from 2008–2009 describes a PDK/"wireless wallet" in development, but I found no evidence of a commercially shipped product implementing the '188 hybrid‑device claims. The '188 disclosure reads as an architecture/enablement patent over the PDK+RDC combination rather than a product datasheet. Treat "shipped an embodying product" as unproven.
• Current status: Not operating as a product company. Proxense has not been dissolved and is not in bankruptcy; it describes itself as continuing to prosecute new patents, and it is actively litigating as plaintiff across 2020–2026. Third‑party registers describe it as an inventor‑controlled NPE / former operating company (see signals below).
• Corroborating "exit" evidence: a 2016‑07‑25 letter from Proxense's IP counsel to Apple (signed off to Tim Cook, in the case file) states Proxense intends to sell its entire patent portfolio in a single transaction and — critically — that "the ultimate purchaser will be able to use the Proxense patents offensively against others," while noting Proxense "has never engaged in any patent enforcement litigation" and there are "no current licenses." Four years later Proxense began a large enforcement campaign.

Assignment timeline

The Assignment Center abstract of title, as surfaced through Google Patents' legal‑events feed, shows one reassignment of record for US 9,049,188. No post‑issuance transfers, security interests, mergers, name changes, or releases appear in the record retrieved. The patent is still held by the original assignee.

• Execution date: not captured / recorded 2014‑03‑21 — Reel not captured/not captured
  • Conveyance: Assignment (recorded string: "ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)")
  • Assignor: BROWN, DAVID L. (individual — the sole inventor)
  • Assignee: PROXENSE, LLC (Bend, OR)
  • Correspondent: not captured in the record retrieved. (The recurring prosecution correspondent for this family is Patent Law Works LLP — Greg Sueoka, 201 South Main Street, Suite 250, Salt Lake City, UT 84111, which is the attorney‑of‑record firm printed on related Proxense patents such as US 11,080,378. That is a prosecution correspondent, and I am not asserting it filed the assignment recording.)
  • Context: Invention‑to‑company assignment — the routine perfecting assignment from the individual inventor to the operating company that filed the application. It is the only title event between filing and today, and it predates the first enforcement suit by roughly six years.

Post‑2014 events with no corresponding assignment record (context only, not title transfers):

• 2015‑06‑02 — Patent issues naming Proxense, LLC as assignee.
• 2021‑03‑08 — Proxense, LLC v. Samsung (W.D. Tex. 6:21‑cv‑00210) filed on the '188 patent, among others.
• IPR2021‑01438 — Samsung IPR against the '188 patent; terminated by settlement (oral hearing 2022‑11‑29).
• 2024‑03‑18 — Proxense, LLC v. Apple, Inc. (6:24‑cv‑00143) filed asserting the '188 patent; Proxense later moved to dismiss '188 with prejudice and substitute '289 from the same family (2024‑09‑26).
• IPR2025‑00562 — Apple IPR against the '188 patent; instituted, pending.

Bottom line for this section: there is no chained‑LLC, no fire‑sale, no securitization, and no transfer‑to‑asserter on this patent. The ownership story here is the mirror image of the classic NPE chain — the original operating company itself became the non‑practicing enforcer and never had to sell the patent to a shell.

NPE / troll-pattern signals

1. Shell‑entity transfer — not present

The only recorded conveyance is Brown → Proxense, LLC (recorded 2014‑03‑21), the original applicant/assignee — not a licensing‑only LLC with an "IP/Patents/Licensing/Holdings/Ventures" suffix. No single‑purpose Delaware/Texas LLC, no registered‑agent‑service address, and no post‑issuance transfer to a third party appear in the record. Proxense is an Oregon LLC that was the operating company; it became non‑practicing in place rather than by transferring the patent. (Note: Proxense's own 2016 letter proposed a portfolio sale to "a single purchaser," but no such assignment was ever recorded on this patent — so this is context, not a shell transfer.)

2. Known asserter in the chain — present

Proxense is not on the enumerated list (Acacia, Marathon, IV, IPNav, Wi‑LAN, Conversant/Mosaid, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation, Spangenberg), but the criterion expressly sweeps in "any entity surfaced by Unified Patents or RPX as a high‑frequency plaintiff," and Proxense is squarely that:

• Unified Patents patent page for US 9,049,188 lists Parent Company / Assignee: Proxense LLC, and Unified's PTAB portal labels Proxense as "NPE (Small Company)" (e.g., IPR2024‑00776, Microsoft v. Proxense, and IPR2025‑00600, Apple v. Proxense).
• Unified Patents PATROLL contests describe the patents as "owned and asserted by Proxense LLC, an NPE."
• RPX (Q1 2021 "In Review," p. 5) identifies "inventor‑controlled NPE Proxense, LLC" as launching a mobile‑payments campaign in March 2021.
• ip fray (2026) describes Proxense as "a non‑practising entity (NPE) and former operating company."

Documented assertion set for the '188 patent and family: Proxense v. Target (6:20‑cv‑00879), v. Urban Outfitters (1:20‑cv‑01007), v. Samsung (6:21‑cv‑00210), v. Google (6:23‑cv‑00320), v. Microsoft (6:23‑cv‑00319), v. Apple (6:24‑cv‑00143), v. Intel (6:24‑cv‑00283), v. LG (6:24‑cv‑00302), v. Hyundai (6:25‑cv‑00016). Unified Patents/RPX‑linked defensive activity against the family includes IPR2021‑01438 (Samsung), IPR2025‑00562 (Apple), IPR2024‑00233/00782/00784 (Google), and IPR2024‑00573/00776/00846 (Microsoft).

3. Repeat correspondent across the chain — not present (with caveat)

The chain contains exactly one assignment, so recurrence across links is structurally impossible — there is no second reel/frame entry to compare a correspondent against. The assignment correspondent is not captured in the sources I could reach.

Two related but distinct recurrence patterns are worth recording, clearly labeled:

• Prosecution: Patent Law Works LLP (Greg Sueoka, Salt Lake City, UT) is the attorney‑of‑record firm across the entire Proxense family (appears on US 11,080,378 and the related filings). This is a prosecution correspondent, not an assignment correspondent, and a single firm handling a family's prosecution is unremarkable.
• Enforcement: David L. Hecht / Hecht Partners LLP (125 Park Avenue, New York, NY) is Proxense's lead counsel in every Proxense assertion campaign (Samsung, Google, Microsoft, Apple, Intel, LG, Hyundai) and in the PTAB/CAFC proceedings. Hecht is the recurring face of this portfolio — but again, that is litigation counsel, not correspondence of record on any assignment, so it does not satisfy signal 3 as written. It is the strongest structural tell in this file and belongs in the dossier even though it is not a reel/frame finding.

4. Cascading transfers — not present

Only one assignment, recorded 2014‑03‑21, and zero assignments in the following ~12 years. There is no sequence of chained LLC transfers, no shared correspondent address across assignees, and no common‑principal pattern to flag.

5. Pre‑litigation transfer — not present

The sole assignment (recorded 2014‑03‑21) precedes the first suit filed on this patent (Proxense v. Samsung, 2021‑03‑08) by ~7 years. There is no transfer within 6 months of any suit, and no venue/standing‑driven reassignment.

6. Bankruptcy fire‑sale — not present

No Chapter 7/11 filing, no sale in a bankruptcy proceeding, and no court‑approved asset sale is associated with Proxense or this patent. Note for completeness: Proxense's 2016 offer to sell its entire portfolio (letter to Apple, in the '143 case file) is a public signal of financial distress/monetization intent, but it is not a bankruptcy event, and no such sale was ever recorded against the '188 patent.

7. Privateering — not present

Classic privateering requires an operating company (or its parent) to transfer patents to a separate NPE that asserts on the operating company's behalf against competitors. Here there is no third‑party NPE at all — Proxense owns the patent and asserts it in its own name. Proxense is not a proxy for a product company; it is itself the patent‑holding enforcer.

8. Defensive aggregator — not present (inverse)

The chain does not terminate at RPX, AST, LOT, Unified, or OIN. To the contrary, Unified Patents and its members are adverse to Proxense — Unified has run PATROLL prior‑art contests on Proxense patents and labels Proxense an NPE, and members (Apple, Google, Microsoft, Samsung, Intel) have filed IPRs against the family. RPX appears in this story only as the plaintiff's press‑tracked adversary context, not as a purchaser of the '188 patent. The patent has not been neutralized.

Verdict

NPE — high confidence.

Proxense, LLC is the current assignee (the only recorded assignment is the inventor→company assignment of 2014‑03‑21, with no later transfer), and it is independently and unanimously designated a non‑practicing entity by Unified Patents ("owned and asserted by Proxense LLC, an NPE"; PTAB portal role "NPE (Small Company)"), RPX ("inventor‑controlled NPE Proxense, LLC," Q1 2021 report), and ip fray ("non‑practising entity (NPE) and former operating company"). Its own 2016 correspondence markets the portfolio for offensive use while confirming it had never litigated and had granted no licenses — and it then launched a 2020‑2026 campaign against Target, Urban Outfitters, Samsung, Google, Microsoft, Apple, Intel, LG, and Hyundai, with the '188 patent asserted in the Samsung and Apple actions and hit by IPR2021‑01438 and instituted IPR2025‑00562.

I flag the calibration honestly: on the eight enumerated chain‑specific signals only #2 is present; the ownership record is conspicuously clean (one assignment, zero shells, zero cascades, no defensive termination). The high‑confidence call rests on the combination of (a) documented NPE status by two of the three registers named in the brief, and (b) the assignee's own written statement of pure offensive‑monetization intent combined with the cessation of product operations after ~2012 — the classic "operating company that stopped operating and now enforces" profile.

I'll research US Patent 9049188B1 and its prior-art citations. Let me run several searches.

Let me dig deeper into the specific citations and the IPR proceedings targeting this patent.

Let me gather details on the key prior-art references and the patent's claim set.

Prior-Art Analysis — US Patent No. 9,049,188 B1

Important disambiguation first (per the literal-interpretation rule): Searches for the string "9049188" surface two unrelated documents. The one you asked about is the U.S. patent US 9,049,188 B1 (Google Patents "US9049188B1"). A separate JP 9049188 A (a Japanese published application, 1997-02-18) appears in some foreign search reports — that is a different alphanumeric identifier in a different authority and is not the subject of this analysis. I did not merge the two.

1. Patent identification (as confirmed live, 2026-09-18)

Claims are directed to a "hybrid device" containing an integrated PDK (personal digital key) coupled by a signal line to an integrated RDC (receiver-decoder circuit), with the PDK further communicating wirelessly with an external RDC.

2. Where the "citations" come from — two different lists

There are two distinct citation sets for this patent, and they should not be conflated:

• (A) The face-of-patent "References Cited" — ~105 U.S. patent documents and 46 non-patent literature items (Google Patents shows "Patent Art (105) / Non-Patent Literature (46) / Referenced By (36)"). These run from US 3,665,313 A (Trent, 5/1972) through the 2007–2010 era, plus foreign docs (WO 00/62505 A1; JP H10-49604; WO 01/22724; WO 01/75876; WO 01/77790; WO 2005/050459; WO 2005/086802) and NPL (e.g., Dagan, "Power over Ethernet (PoE) Midspan," 2005). Almost all of these are cumulative background art cited in the IDS; they were never relied on to reject the claims.
• (B) The prior art actually asserted against the '188 patent in the PTAB and district court — this is the set that is genuinely "most relevant," and it is what I detail below.

Caveat on § 102: In the actual proceedings, no single reference was asserted to anticipate the claims under § 102. The challengers framed every ground as obviousness under § 103 (single- or multi-reference combinations). I flag this because § 102 and § 103 are legally distinct; where a reference was argued to disclose "every limitation" alone (Broadcom), it was still pleaded as a § 103 ground.

3. The most relevant prior art (asserted in IPR2025-00562 and IPR2021-01438)

3.5 (Related) Samsung's IPR2021-01438

Samsung challenged the '188 patent (consolidated with IPR2021-01439 on US 9,235,700). Its grounds likewise rested on the Giobbi references and Broadcom; the case settled. Here too the dispute turned on claim construction ("hybrid device," "personal digital key," "receiver-decoder circuit," "signal line"), not on single-reference anticipation.

4. Claim-by-claim summary (asserted art)

No reference was advanced as a standalone § 102 anticipation of any independent claim — the closest is Broadcom, whose "every limitation" argument is anticipation-flavored but was litigated as § 103.

5. Confidence and limitations

• High confidence: identity/bibliographic data of US 9,049,188 B1; the reference set used against it (Giobbi '157, Giobbi '139, Dua, Broadcom) and the claim groupings — these are corroborated by the IPR2025-00562 petition/exhibit list and the Samsung IPR2021-01438 hearing transcript.
• Moderate confidence: exact publication date of Giobbi '157 (2007-10-18) and Broadcom (2005-06-01) — consistent with the search results but I could not open the primary front pages before hitting the search limit.
• Unverified / state explicitly: the qualifying prior-art date for Dua (US 9,042,819); and I did not map each of the ~105 face-of-patent references to specific claims — those are IDS background art, not asserted anticipatory art, and any § 102 mapping for them would be speculative.
• Do not rely on any "JP 9049188 A" or "JP 9049188" entries as the U.S. patent — different authority, different document.

If you want, I can next pull the verbatim claim language of claims 1 and 10 and build element-by-element § 102/§ 103 charts against Giobbi '157 and Broadcom specifically.

I'll research the prior art referenced in US 9049188 to ground this obviousness analysis.

Let me dig into the specific IPR grounds and prior art references asserted against this patent family.

Let me get the precise claim language of the '188 patent and confirm the final outcomes of the key proceedings.

Obviousness Analysis — U.S. Patent No. 9,049,188 B1

Patent: U.S. 9,049,188 B1, "Hybrid Device Having a Personal Digital Key and Receiver-Decoder Circuit and Methods of Use" (Inventor: David L. Brown; Assignee: Proxense, LLC). Granted June 2, 2015 from App. No. 14/171,705 (filed Feb. 3, 2014), a continuation of 13/445,825 (now U.S. 8,646,042), which is a continuation of 12/329,329 (now U.S. 8,171,528), claiming benefit of Provisional 60/992,953 ("Reverse Prox," filed Dec. 6, 2007). Earliest effective priority: Dec. 6, 2007.

Note on identifiers (interpreted literally): the patent at issue is 9,049,188. The reference "Dua" asserted against it is U.S. 9,042,819 — a different number that is easy to transpose; I keep them distinct throughout as they appear on the record.

1. The claims to be assessed

Because the independent claims define the field of the § 103 inquiry, it is worth fixing their scope (built from the already-generated claim/description sections):

• Independent claim 1 (device): a hybrid device with (a) an integrated PDK storing local, secured biometric information for authenticating a user and able to communicate wirelessly with an external RDC; (b) an integrated RDC communicating wirelessly with an external PDK within a proximity zone; (c) the integrated RDC coupled to the integrated PDK by a first signal line; (d) the integrated RDC coupled to at least one other component of the hybrid device by a second signal line; and (e) one or both of the integrated RDC/PDK enabling an application, a function, and/or a service.
• Independent method claim: creating a first wireless link between an integrated RDC of a hybrid device and an external PDK, the hybrid device also having an integrated PDK storing local, secured biometric information; receiving a first signal at the integrated RDC over that link; and generating an enablement signal enabling an application, function and/or service.

The remaining claims are dependents that largely recite implementation details (form factors, cell-phone embodiments, etc.).

Person of ordinary skill (POSITA) for the '188 family: a bachelor's degree in CS/EE/computer engineering (or equivalent) with roughly 2–4 years of experience in wireless authentication, secure portable devices, or RF/wireless networking — a level the Board has repeatedly adopted for these same references and this same specification.

2. The prior art on the record

Two bodies of art are relevant, and both appear in the material associated with this patent.

(A) References cited on the face of the patent ("Prior Art"/Citations section). The '188 patent lists roughly 100+ U.S. patent documents and a set of foreign/NPL items, including U.S. 5,623,552 (Cardguard); U.S. 6,325,285 (smart card with integrated fingerprint reader); U.S. 6,728,397 (McNeal); U.S. 6,879,966 (Indivos); U.S. 7,231,068; U.S. Pub. 2006/0113381 (Hochstein, fingerprint-enabled smartcard); U.S. Pub. 2006/0208066 (RFID token with multiple-interface controller); WO 00/62505 ("Digital Home Network…"); WO 2005/050459 ("Digital Content Security System"); WO 2005/086802 ("Linked Account System Using Personal Digital Key (PDK‑LAS)"); plus NPL such as Dagan's Power over Ethernet (PoE) Midspan and Beaufour & Bonnet, Personal Servers as Digital Keys (PerCom 2004). Several of these are the same family's own earlier PDK/RDC disclosures.

(B) The invalidity references developed in litigation/PTAB. These are the substantive § 103 references and are the strongest ground:

These references are the ones actually instituted and litigated: together they formed Grounds 1–3 against the '188 in Samsung's IPR2021‑01438 (instituted, later terminated by settlement), and against the sibling patents. The same or substantially the same grounds drove:

• IPR2024‑00407 (Microsoft v. Proxense, U.S. 9,679,289) — Final Written Decision July 17, 2025: all challenged claims unpatentable under § 103 (FWD).
• IPR2024‑00573 (Microsoft/Apple v. Proxense, U.S. 8,646,042 — the direct parent of the '188) — all challenged claims unpatentable (FWD).
• IPR2024‑00405 (Microsoft, U.S. 10,073,960) and IPR2025‑00562 (Apple, U.S. 9,049,188 — this patent) — same grounds; the '188 proceeding is reported as instituted and, per trade press, the claims found obvious.

3. Combination 1 — Giobbi '157 + Giobbi '139 (+ Dua)

This is the strongest combination: each limitation of independent claim 1 is supplied by explicit teachings, and every element is supported by a showing the Board already credited against the same specification.

Limitation mapping (claim 1):

• (a) integrated PDK storing local, secured biometric information; wireless to external RDC → Giobbi '157's PDK 102 with tamper-proof memory storing biometric profile data and communicating with a reader/RDC.
• (b) integrated RDC communicating wirelessly with an external PDK within a proximity zone → Giobbi '157 reader 108 (RDC 304) communicating with PDK 102 when within its proximity zone; Giobbi '139 likewise discloses an RDC communicating with a PDK within range; Dua's Reader Unit 304 is a further example of an integrated RDC coupled to an RFID Tag Unit.
• (c) first signal line coupling the integrated RDC to the integrated PDK → Giobbi '157 shows the reader coupled to the device's other components by a signal line; Giobbi '139 expressly teaches a non-wireless (e.g., serial) connection between a PDK and an RDC co-located in one device — which is precisely the claimed "first signal line."
• (d) second signal line to at least one other component → Giobbi '157 shows RDC 304 coupled by a second signal line to biometric reader 302 (the "other component"); Giobbi '139 shows a storage device controlled by a signal line from the RDC; Dua shows the reader internally wired to the processor/transmitter/antenna/power of the mobile device.
• (e) enabling an application/function/service → Giobbi '157: on valid PDK credentials the RDC "completes the transaction," i.e., "enabling access to secure physical or digital assets"; Giobbi '139: the integrated RDC enables a function/service on the device (e.g., playing digital content) when an authorized PDK is present.

Motivation to combine (KSR rationales):

1. Same field of endeavor / common problem. All three address secure, proximity-based access using a PDK/RDC architecture. Giobbi '157 and Giobbi '139 share an inventor group and architecture, making their techniques mutually compatible.
2. Predictable result / design choice. Placing a known security component (an RDC) into a known portable platform (a cell phone) to protect that platform is the routine "arrangement of old elements" that yields no more than expected.
3. Explicit teaching in the secondary references. Giobbi '139 itself calls integrating an RDC into a cell phone an "enhancement" to hardware-key-based security; Dua explicitly teaches that combining both reader and tag functionality in one device provides interconnection and convenience.
4. Express "both sides of the transaction" benefit. A device with an integrated PDK and an integrated RDC can act on both sides of a secure exchange (present credentials and read others' credentials), which is an articulated, practical advantage.

Reasonable expectation of success: Giobbi '139 and Dua both teach the very integration at issue, confirming technical feasibility; the combination is a mechanical collocation of proven components.

4. Combination 2 — Broadcom (EP 1 536 306 A1), alone

Broadcom is the "single-reference" ground and is nearly anticipatory in content:

• Its "Access Device" is the claimed hybrid device, and is expressly described as a mobile phone (thus also hitting the cell-phone dependent claims).
• Its integrated wireless proximity reader is the claimed "integrated RDC" communicating with an external token within a proximity zone.
• Its internal authentication component and data memory storing user credentials (including biometrics) is the claimed "integrated PDK storing local, secured biometric information."
• Its internal signal lines coupling the reader, authentication circuitry and other components satisfy the "first/second signal line" limitations.
• Gating a network/service via an external "access controller" is the claimed "enabling an application, function and/or service."

Because Broadcom discloses every limitation in a single body, it renders claim 1 obvious (and, to the extent its disclosure is as complete as Petitioners contended, anticipates it). The existence of a controller-driven "access device" whose reader both reads external tokens and relies on internally stored credentials is exactly the claimed architecture.

5. Combination 3 — Broadcom + Giobbi '157

For the claims requiring additional furniture — the external PDK being included in jewelry or a watch, or relying on an external authentication database separate from the merchant — Broadcom is combined with Giobbi '157. Broadcom teaches its external token can take wearable form factors (e.g., a badge); Giobbi '157 expressly teaches integrating a PDK into watches and jewelry and using external authentication in transactions. A POSITA would consult known token form factors to improve user convenience — a classic motiveless "design alternative" that KSR deems obvious.

6. Additional, secondary combinations from the face-of-patent art

Even setting aside Giobbi/Broadcom, the Citations section alone supplies combinable art for specific features:

• Smart-card/biometric integration: U.S. 6,325,285 (integrated fingerprint reader) + U.S. Pub. 2006/0113381 (fingerprint-enabled smartcard) + U.S. 5,623,552 (self-authenticating ID card) together teach the "local, secured biometric information for authenticating a user" stored on a portable secure element — a natural combination with the PDK/RDC architecture.
• Combined reader/tag in one device: U.S. Pub. 2006/0208066 (RFID token with multiple-interface controller) teaches a token/reader composite, supporting the "integrated PDK + integrated RDC" requirement.
• Power/interconnect: Dagan's PoE Midspan NPL supports the "physical interconnect … receive power" implementation detail appearing in the dependent claims.
• Linked-account services: WO 2005/086802 ("Linked Account System Using Personal Digital Key (PDK‑LAS)") supports the transaction/service-enablement dependents.

These are secondary; they reinforce rather than replace Combinations 1–3.

7. Anticipated rebuttals and why they do not defeat obviousness

1. § 112(f) / means-plus-function arguments. Proxense's principal response in the family IPRs was that "enabling one or more of an application, a function and a service" and the "integrated RDC" lacked sufficient structure and invoked § 112(f). The Board rejected that theory (no "means" term; "RDC"/"application"/"function"/"service" connote structure to a POSITA; the explicit claim requirements sufficiently limit the claims). That argument therefore does not create a § 103 gap.
2. No teaching away. Giobbi '139's express endorsement of integrating an RDC into cell phones is the opposite of a teaching away.
3. No unexpected results / nexus. The asserted benefits (one device that both presents and reads credentials; secure SIM/content extension) are the predictable consequences of the proposed combinations, absent evidence of a surprising result or a nexus to an objective indicium.
4. Prosecution-history posture. The claims issued with a largely conventional biometric/smart-card citation set and, on the PTAB record, without the Examiner substantively considering the Giobbi/Broadcom teachings — which the Board treated as material error (see the § 325(d)/Advanced Bionics discussion in the '960 Petition).

8. Conclusion

Under the Graham/KSR framework, U.S. 9,049,188 B1 would have been obvious over the prior art on the record:

• Primary ground — Giobbi '157 in view of Giobbi '139 (and, in the alternative, further in view of Dua): renders independent claim 1 (and the method independent claim) obvious, with the integrated-PDK-plus-integrated-RDC architecture, the first/second signal lines, the proximity-zone wireless link, and the biometric-cum-service-enablement limitations each supplied by explicit teachings and joined by strong same-field, same-problem, predictable-result motivations.
• Alternative single-reference ground — Broadcom (EP 1 536 306 A1): discloses a mobile "access device" that is the claimed hybrid device and renders the independent claims obvious on its own.
• Supplementary ground — Broadcom in view of Giobbi '157 for the dependent form-factor/transaction limitations, and the face-of-patent references for specific biometric/smart-card and composite reader/token features.

This conclusion is consistent with the adjudicated outcomes in the same family: the PTAB found all challenged claims of the parent U.S. 8,646,042 and of U.S. 9,679,289 unpatentable under § 103 over these references, and the parallel Apple proceeding on this '188 patent is reported to have found the challenged claims obvious. (Caveat: I do not have the four corners of the '188-specific Final Written Decision text in front of me; the '188-specific outcome is drawn from the instituted grounds and trade-press reports, and the Samsung IPR2021‑01438 against the '188 was terminated by settlement rather than decided on the merits. The claim-to-reference mapping above is stated with high confidence because it tracks the Board's credited findings against the identical specification.)
