US 11599734

I'll search for this specific patent number across the sources you named.

The first searches returned mostly unrelated documents. Let me narrow with the title and litigation leads from the patent record.

US Patent 11,599,734 B2 — Analyst Summary

Bottom line up front: I found solid bibliographic, prosecution, and litigation data for exactly US 11,599,734 (no similar-number confusion), but I could not retrieve the verbatim granted claim text or the verbatim abstract from an authoritative source within this session. The claim summary below is therefore reconstructed from (a) the specification text supplied in the patent record and (b) a third-party litigation-complaint analysis, and is flagged as such. No Court of Appeals for the Federal Circuit 2026 docket for this patent was located.

1. Bibliographic data (high confidence)

Classifications: G06K 7/10; G06K 19/077; G06Q 20/22; G06Q 20/32; G06Q 20/34; G06Q 20/40; G07G 1/00; current U.S. Class 455/500 (plural transmitters or receivers).

2. Abstract

I do not have authoritative abstract text for this patent — the abstract body was not present in the retrieved record. What is verifiable is that Google Patents indexes the patent's "prior art keywords" as state, switch, RFID tag, RFID, circuit, and that the pre-grant publication's Summary (identical specification) describes the invention as including "the use of shielding in relation to RFID tags," shielded containers for passports/credit cards/driver's licenses, and, separately, switchable RFID tags whose detectability/readability is controlled by a switch. Given the title and the field-of-invention statement, the abstract almost certainly emphasizes inductive (short-range) communication by a cellular telephone rather than the passport/shielding material. I would not quote it as verbatim.

3. Specification overview (from the authoritative full text)

Notable structural point: this is a continuation with an inherited 2005-era specification. The stated field is: "The invention is in the fields of electronic passports, and more specifically in the field of electronic passports including shielding and/or switchable RFID tags." The bulk of the disclosure is therefore about:

• RF shielding for RFID-tagged IDs (wallets, purses, passport covers, clamshell IDs, shielding inserts, shield pages).
• Container/vial/room state detection using shielding and an RFID tag or reader (event logging, alarms, access control).
• Switchable RFID tags — remotely powered RFID tags with an electronically, mechanically, magnetically, optically, or wirelessly controlled switch; ON/OFF state stored in state memory; a key memory and switch logic that change the ON/OFF state upon comparison of received data with a stored key; membrane switches, sliding switches, short-circuit vs. open-circuit switch placements.
• A portable communication device "such as a cellular telephone, a blackberry, a wireless personal digital assistant, or the like" including an optionally switchable RFID tag that communicates with local devices by RFID and with distant devices by Bluetooth/WiFi/WiMAX/802.11/cellular — the portion from which the present title and claims evidently derive. This passage recites: user-interface control of the RFID tag; entry of security data, credit/debit card numbers, and account numbers; memory devices insertable into slots so one phone can carry multiple financial accounts with user-selectable accounts; use of phone power (or harvested RF power) to power the tag; voice-recognition approval of an RFID transaction; entering a reader ID or transaction amount; two or more communication modes at different frequencies with separate or electronically configurable antennas.

So the title/specification mismatch is real and should be understood as a continuation claim-set drawn from a subset of a broad original disclosure.

4. Independent claims — plain-language overview

Confidence level: moderate/low. Verbatim claim text not obtained. Two independent inputs:

(a) Litigation-complaint analysis (third-party AI summary of SureCell Transactions LLC v. [Samsung Electronics America, Inc.](/litigations/by-plaintiff/Samsung%20Electronics%20America%2C%20Inc.), E.D. Tex. 2:26-cv-00106): the '734 patent is described as directed to "methods of performing financial transactions by communicating with a point-of-sale device," where the methods involve changing the authentication state of the cellular telephone and communicating financial information using an inductive coupling responsive to that state. It identifies the asserted independent claims as at least claims 1, 15, and 23, and characterizes the accused conduct as "placing the phone near a POS terminal and activating a secure state to communicate financial data."
https://ai-lab.exparte.com/case/dct/txed/2:26-cv-00106/doc/analysis/9

Reading that against the specification, the three independent claims most plausibly read as:

• Claim 1 — Method (financial transaction via cellular telephone + POS): a method performed with a cellular telephone in which the phone is brought into proximity with a point-of-sale/reader device; an authentication or security state of the telephone is changed (e.g., unlocked, access code or biometric entered); and, responsive to that changed state, financial account information is communicated over an inductive coupling to the point-of-sale device.
• Claim 15 — Method (related but separately scoped): a further independent method in the same family — likely framed around receiving power/data inductively, and/or around the switch/state change gating the inductive transmission of account information. The specification's support for this includes the embodiments in which the RFID tag is "activated" only after an access code or user action, and in which the phone's own power source drives the tag.
• Claim 23 — Method (broader inductive-communication method): the broadest of the three — most likely a method of inductive communication between the cellular telephone and a local device in which a state change gates whether/when a return signal carrying stored data (account number, digital key) is transmitted.

(b) Specification "invention" definitions that are claim-like and likely correspond to elements of these claims: a switchable RFID tag with state memory storing an ON/OFF state and switch logic that changes that state after comparing received data to a stored key; a communication device with an 802.11 or cellular transmitter, a user interface for entering data, and a switchable RFID tag that switches between active and inactive states responsive to that data; and a communication device with slots for memory devices carrying first and second data, plus a user interface to select which data (financial account information or a digital key to a lock) is transmitted.

What I cannot confirm: the exact wording, ordering, and breadth of claims 1, 15, and 23; the total claim count; and whether any of these are apparatus rather than method claims. The '734 record also shows the specification text I received being truncated mid-sentence (at "Membrane Sw…"), before the claims column, which is why I am not quoting claim language.

5. Litigation and appeal status

District court (confirmed):

• Plaintiff: SureCell Transactions LLC (current assignee, per 2026-01-15 assignment)
• Defendants: Samsung Electronics America, Inc. et al.
• Case: 2:26-cv-00106, U.S. District Court for the Eastern District of Texas, Marshall Division
• Filed: February 12, 2026
• Judge: Rodney Gilstrap; Magistrate Roy S. Payne; jury demand by plaintiff
• Nature of suit: 830 Patent; cause 15:1126; damages demand $500,000,000
• Other asserted patents in the same complaint reportedly include US 11,989,612 and US 12,039,396 (further Colby/Mynette continuations). Google Patents also records this as the "first worldwide family litigation" (Darts-IP family 80356977).

CAFC 2026 docket (negative finding):
I searched specifically for a Federal Circuit 2026 appeal involving US 11,599,734 and/or Mynette Technologies / SureCell Transactions and found no CAFC docket, order, or opinion for this patent. Given the E.D. Tex. case was filed in February 2026, an appeal would be premature. I am stating this as a "not found," not as proof of absence — my search coverage of CAFC 2026 dockets was limited and I would need a direct PACER/CAFC docket lookup to confirm.

6. Uncertainties and caveats I want on the record

1. Abstract and claim text are not verbatim-verified. Do not treat the claim descriptions in §4 as quotations or as a legal construction.
2. The "expired – lifetime / adjusted expiration 2026-05-07" status comes from the Google Patents record. Note that your prompt states the current date as April 26, 2026, while the dataset indicates the record was fetched 2026-09-23; either way, term appears to run from the 2006-05-07 non-provisional filing in the chain, yielding a ~May 2026 expiration. The pre-grant publication's earlier U.S. patents in the chain (e.g., US 7,924,156; US 8,816,826; US 9,569,777; US 11,170,185) are the better references for the underlying priority case.
3. The complaint analysis I relied on for claim identification is a third-party AI-generated summary, not the complaint itself. Its own text shows cross-contamination between the '734 patent and a co-asserted patent about a mechanical multi-ON-state RFID switch; the "financial transaction / authentication state / inductive coupling" description is the one attached to the '734 number, but I could not independently verify it against the complaint PDF.
4. Title vs. disclosure tension is genuine, not an error I introduced. The patent is titled as a cellular-telephone inductive-communication invention while its stated field and most of its disclosure concern electronic passports and RFID shielding. This is consistent with a continuation drawing narrow claims from a broad 2005 disclosure, but it is worth noting for claim-construction purposes.
5. I did not find any PTAB proceeding (IPR/PGR) against US 11,599,734 in the results reviewed. That is a "not found," not a verified absence.

If you need the verbatim abstract and full claim set, the authoritative sources to pull directly are the USPTO PatentCenter/Patent Application Full-Text file for 17/697,923, the granted-PDF at https://patentimages.storage.googleapis.com/.../US11599734.pdf, or the E.D. Tex. complaint (2:26-cv-00106, Dkt. 1) with its Appendix A claim charts.

I'll search for litigation specifically involving US 11,599,734.

Let me search the litigation aggregators more specifically.

I have strong results. Let me verify a few more angles — docket status, any PTAB challenges, and any other suits.

Litigation Involving U.S. Patent No. 11,599,734

Bottom line

I found one district-court case that squarely asserts the '734 patent, plus one related family case against the U.S. government that does not assert the '734 patent itself but is highly relevant because of its covenant-not-to-sue remedy. I found no Federal Circuit appeal and no PTAB proceeding involving the '734 patent.

1. Directly asserts U.S. 11,599,734

SureCell Transactions LLC v. [[Samsung Electronics America, Inc.](/litigations/by-plaintiff/Samsung%20Electronics%20America%2C%20Inc.) et al.](/litigations/by-defendant/Samsung%20Electronics%20America%2C%20Inc.%20et%20al.)

Patents asserted in the same complaint (six): U.S. 7,924,156; 11,347,949; 11,599,734; 11,687,741; 11,989,612; and 12,039,396.

The '734-specific allegations (as reported): The complaint characterizes the '734 patent as directed to "methods of performing financial transactions by communicating with a point-of-sale device," where the methods involve changing the authentication state of the cellular telephone and communicating financial information using an inductive coupling responsive to that state. Asserted independent claims are reported as at least claims 1, 15, and 23, and the accused conduct is described as "placing the phone near a POS terminal and activating a secure state to communicate financial data." Accused instrumentalities are described as a broad range of Samsung devices, including Galaxy S / Note / Z Fold / Flip / A series smartphones, Galaxy Watch wearables, and Galaxy Tab tablets, in connection with Samsung Pay / Samsung Wallet, Samsung Blockchain Wallet, and third-party payment apps.

Google Patents family/litigation flag: The '734 record lists this as the "First worldwide family litigation filed" for Darts-IP family 80356977, which is consistent with this being the first and only suit directly on the '734 patent.

2. Related family litigation — same inventor/owner, but the '734 patent was NOT asserted

Mynette Technologies, Inc. and Steven M. Colby v. United States

Why this matters for the '734 patent (flag for your attention): As a sanctions remedy for plaintiff's counsel's undisclosed conflict, the Court ordered a covenant not to sue (CNS) drafted to cover "all of Mynette's current and future patents (regardless of the date filed or acquired) related to the technology in discovery production at issue in this suit," naming the Mynette Parties (Mynette, Robert Yorio, and Steven M. Colby) and running to the United States, Thales DIS USA, and Idemia. The scope of the "Restricted Patents" was left to a meet-and-confer. Because the '734 patent is a Colby/Mynette continuation in the same RFID/switchable-tag family, whether the CNS reaches the '734 patent — and whether it survived the January 2026 assignment of the '734 patent to SureCell Transactions LLC (a non-"Mynette Party") — is a real open question that could bear on the Samsung case. I am flagging this as an analytical observation, not as a verified legal conclusion; the final CNS language and its patent list were not retrieved verbatim.

3. Negative findings (stated as "not found," not as proof of absence)

• No Federal Circuit appeal involving U.S. 11,599,734. I searched CAFC 2026 materials and found nothing tied to this patent number, to SureCell Transactions, or to Mynette Technologies. My search did surface IdeaHub Inc. v. Unified Patents, LLC, No. 2024-1684 (Fed. Cir., Rule 36 judgment April 10, 2026) — a false positive (PTAB PGR2022-00044, unrelated technology) that I exclude. An appeal of the '734 case would also be premature: the E.D. Tex. complaint was filed February 12, 2026.
• No PTAB proceeding (IPR/PGR) against U.S. 11,599,734 was located. Note that the Samsung defendants retained Quinn Emanuel in the parallel Apple v. Samsung matter and Unified Patents is a frequent petitioner; a post-suit IPR petition is plausible but I found no filing.
• No other district-court defendant found. I searched for additional SureCell or Mynette infringement actions and found none beyond the matters above. The only other "Mynette"-captioned hits were the CoFC case and unrelated parties.

4. Caveats and contradictions you should know about

1. Date inconsistency across sources. Your prompt sets the current date as April 26, 2026, but the authoritative patent record was fetched 2026-09-23, and one Korean trade-press article covering this suit is dated 2026-09-05. I have treated the later-dated search results as ground truth per your instructions, but the case-status statement ("pending") reflects the most recent docket snapshot available to me in this session, not a live PACER pull.
2. Claim-identification is second-hand. The "financial transaction / authentication state / inductive coupling" description of the '734 claims, and the "at least claims 1, 15, 23" identification, come from a third-party AI-generated complaint analysis, not from the complaint PDF or a claim chart. That analysis also shows visible cross-contamination with a co-asserted patent (the Nartron/UUSI '183 patent appears in one of my hits, and the source's own text mixes the '734 and '612/'396 descriptions). Do not treat the claim characterization as a quotation or a construction.
3. Mixed-up patent numbers inside the sources. The complaint analysis refers to the asserted patents as the '949, '741, and '734 patents in one place, while the complaint's patent list as reported by the Korean article is '156, '949, '734, '741, '612, '396. Both are consistent as to the '734 patent's presence; the numbering is reproduced literally above.
4. The '734 patent is listed as expired. The Google Patents record shows "Expired – Lifetime; Adjusted expiration 2026-05-07" (term running from the 2006-05-07 non-provisional in the chain). If that is accurate, the asserted term would end during the pendency of the Samsung case — a damages-limiting fact worth verifying in the docket, but not something the litigation records I retrieved address.
5. The CoFC covenant-not-to-sue analysis in §2 is mine, not a court's. I could not retrieve the finalized CNS patent list. Treat it as a due-diligence lead, not a finding.

Recommended next steps to confirm ground truth: pull PACER for E.D. Tex. 2:26-cv-00106 (Dkt. 1 and Appendix A claim charts) for verbatim '734 claim assertions and the full defendant list; pull the finalized CNS from Fed. Cl. 1:16-cv-01647 (ECF Nos. 169–187) to test the covenant's scope against the '734 patent and the SureCell assignment; and check PTAB for any post-February-2026 IPR/PGR petitions naming SureCell Transactions LLC as patent owner.

I'll research this proceeding to fill in what's publicly available, then report.

Let me run additional targeted searches on the specific proceeding and the patent owner's PTAB history.

Let me hunt for the specific petition and any companion filings against the same patent family.

PTAB / AIA Trial Report — U.S. Patent No. 11,599,734 B2

Patent: US 11,599,734 B2, "Methods of inductive communication in a cellular telephone" (app. 17/697,923; issued 2023-03-07; inventor Steven Michael Colby; current owner SureCell Transactions LLC per assignment recorded 2026-01-15).
Report date: 2026-09-23.

Search note / correction to the earlier section. The previously generated summary stated "I did not find any PTAB proceeding (IPR/PGR) against US 11,599,734." That negative finding is now superseded: the canonical USPTO Open Data Portal list supplied in this prompt shows IPR2026-00508 filed 2026-09-22 — i.e., one day before today's date. The earlier section was a "not found" from limited coverage, not a verified absence, and it is now resolved against that finding. I did not find any other AIA trial on this patent, and I have not invented any.

Proceedings overview

One (1) AIA trial proceeding on file for US 11,599,734: 1 active/pending (IPR2026-00508, filed 2026-09-22), 0 with claims invalidated, 0 with claims sustained, 0 settled, 0 institution denials, 0 FWDs, 0 Federal Circuit appeals. Bottom line defensive posture: the patent is entirely untested at the Board. Nothing has been canceled, nothing has been sustained, no estoppel has attached, and no claim-level outcome exists yet — Samsung's petition is one day old, so there is no institution decision, no assigned merits panel (publicly), no preliminary response, no FWD, and no appeal. For a defendant facing this patent today, the honest read is: the earlier-generation sibling patents were tested in court (Fed. Cl. claim construction) but the '734 claims have never been construed by any tribunal, and no PTAB estoppel exists for anyone.

IPR2026-00508 — [[Samsung Electronics Co., Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.) v. SureCell Transactions LLC (patent owner of record)

• Type: Inter Partes Review (35 U.S.C. §§ 311–319). PGR is not available — the 9-month § 321(c) window closed 2023-12-07. CBM review is not available — the transitional program sunset 2020-09-16. IPR is the only vehicle left, and § 311(b) limits it to § 102 / § 103 grounds on patents and printed publications only — no § 112 or § 101 theories.
• Filed: 2026-09-22 (last modified 2026-09-22).
• Status (verbatim from structured data): Pending. Plain-English gloss: petition filed but not yet accorded/noticed; no preliminary response, no institution decision, and no trial yet.
• Judge panel: Not public / not found. Under current Office practice the institution decision is being made at the Director level (Under Secretary John A. Squires) rather than by a three-APJ merits panel — the June–May 2026 "Notices of Decisions on Institution" I reviewed are all captioned "Before JOHN A. SQUIRES." A merits panel is typically not identifiable until institution. I will not speculate on panel composition.
• Petition grounds: Not retrievable in this session. The petition PDF and its grounds/claims/exhibits were not publicly accessible through the sources I could reach. I am not going to guess at the claims challenged or the art. Given the patent's field, the realistic § 102/§ 103 universe is 2005-era short-range/inductive-payment and switchable-RFID art (NFC/contactless-payment and RFID-tag publications), but that is inference, not a reported ground.
• Institution decision: None yet. Statutory timing: § 314(b) requires a decision within 6 months of the date the petition is accorded a filing date — so a decision is due roughly 2027-03-22 if the petition is accorded on filing. Patent Owner's preliminary response under 37 C.F.R. § 42.107(b) would be due about 3 months after notice of accord (~2026-12-22), unless waived.
• Final Written Decision: None. If instituted, § 316(a)(11) puts the FWD deadline 1 year after institution (~March 2028, subject to a § 316(a)(11) good-cause extension of up to 6 months). There is therefore no claim-level outcome to report.
• Settlement / termination: None reported. Status is Pending, not Terminated. No § 317 joint motion to terminate appears in the record I reviewed.
• Appeal: None possible yet. No FWD means nothing is appealable; no Federal Circuit docket for this patent was located.
• Defensive value: Low today, high optionality. Because nothing has been canceled, the proceeding gives a current defendant no claim-level ammunition — you cannot say "claim 1 is dead." What it does give you is: (a) a live § 315(b) safe harbor for Samsung (petition filed ~7 months after the 2026-02-12 E.D. Tex. complaint, comfortably inside the one-year bar), (b) a stay argument, and (c) a roadmap — the petition is public, so a co-defendant can mine its grounds, and any institution would trigger § 315(e)(2) estoppel against Samsung and its privies only.

Parallel litigation anchor (context, not a PTAB event): SureCell Transactions LLC v. Samsung Electronics America, Inc. et al., No. 2:26-cv-00106 (E.D. Tex., Marshall Div.), filed 2026-02-12, Judge Rodney Gilstrap, Magistrate Roy S. Payne, jury demand, damages demand $500,000,000. The complaint asserts six Colby/Mynette-family patents against Galaxy phones, watches and tablets: 7,924,156; 11,347,949; 11,599,734; 11,687,741; 11,989,612; and 12,039,396. For the '734 patent the asserted independent claims are reported as at least claims 1, 15 and 23, with the infringement theory being Samsung Pay NFC transactions gated by an authentication state (phone near a POS terminal → secure/authenticated state → financial data over an inductive coupling). Source for the asserted-patent list and the '734 description: https://ai-lab.exparte.com/case/dct/txed/2:26-cv-00106/doc/analysis/9 and https://www.the-biz.co.kr/news/articleView.html?idxno=[707046](/patent/707046). Caveat carried forward from the earlier section: the complaint-analysis page is a third-party AI tool's summary, not the complaint PDF, and it shows cross-contamination with a co-asserted mechanical-multi-ON-state patent. Treat the "claims 1, 15, 23" identification as unverified.

Strategic summary

Which claims are canceled / sustained / untested. For US 11,599,734 the answer is simple and unambiguous: every claim is UNTESTED. There are zero canceled claims and zero sustained claims because there is no FWD, no institution decision, and no certificate. If a demand letter or expert report cites claims 1, 15 and 23 (the reported asserted independent claims), there is no PTAB disposition to point at. The prior negative outcome that did exist for this family is in a different forum: the U.S. Court of Federal Claims construed "ON/OFF State," "Responsive State," "Shield"/"Shielding," and "Switch Logic" (holding § 112 ¶ 6 did not apply to "switch logic") for ancestors US 7,719,425; 7,924,156; 9,524,458; and 9,569,777 in Colby v. United States, No. 1:16-cv-01647 (Fed. Cl., Memorandum Opinion and Order, Aug. 2018). That order, https://cases.justia.com/federal/district-courts/federal-claims/cofce/1:2016cv01647/33829/68/0.pdf, is the most useful existing intrinsic authority on family terminology and is worth pulling before any claim-construction or IPR briefing; note the government appeared as intervenor-defendant in that matter, so the paper trail for this family is already partly governmental.

Estoppel landscape. No estoppel has attached to anyone, from anywhere. § 315(e)(2) estoppel is triggered only by a final written decision, and none exists. Samsung is not estopped now and would not be estopped unless and until an FWD issues in IPR2026-00508 — and even then only as to Samsung and its privies/RPIs, on grounds raised or that reasonably could have been raised. For any other defendant facing this patent, all § 102/§ 103 patent-and-printed-publication grounds remain fully available, both in the district court and in a fresh IPR (subject to that defendant's own § 315(b) clock, running from its own service of process). Because this patent expired on the Google Patents record's "adjusted expiration" of 2026-05-07, any remaining exposure is historical/past damages, which is exactly the kind of exposure an invalidity win eliminates.

Pattern signals and risks to watch. Three are worth flagging:

1. Same petitioner, same campaign, likely multiple petitions. The complaint asserts six patents in one family, and Samsung has a documented practice of filing coordinated petition waves against an NPE's asserted set within roughly six months (e.g., its seven-petition wave against Netskope's asserted set). I could not confirm companion IPRs against the sibling patents from the sources I reached, and I am not asserting they exist — the canonical list gives you only the '734 number. If sibling petitions are filed, expect the same RPI naming convention ("Samsung Electronics Co., Ltd. et al.," i.e., SEC + SEA).
2. Stipulation-scope litigation is a live risk for Samsung. Samsung's Sotera-plus stipulations have been attacked by patent owners — most on point, Wilus's Request for Director Review in Samsung v. Wilus, IPR2025-00988 (U.S. 10,687,281), accused Samsung of promising the Board it would not use petition art in district court (even in combination with system art) and then serving an invalidity expert report relying on that same art. Expect SureCell to probe the scope of any Samsung stipulation used to defeat a discretionary-denial argument. If Samsung wants a stay and an institution, it should stipulate broadly and then actually honor it.
3. No defensive aggregator here. The "Unified Patents" text in the patent record is data-source attribution for Google Patents' litigation field, not evidence that Unified filed a challenge. There is no disclosed Unified/third-party petitioner in IPR2026-00508 — the petitioner is Samsung, a named litigation defendant.

Director-level discretionary practice will decide this one's fate more than the merits. With institution decisions currently being routed through Under Secretary Squires and the Director's discretionary-denial practice active (compare Tesla v. Bulletproof Property Management, IPR2026-00204 et al., designated informative 2026-06-15 — no scheduled trial date plus a broad stipulation weighed against denial; and the U.S.-manufacturing memorandum), expect the institution fight on IPR2026-00508 to turn on parallel-litigation discretion and the breadth of Samsung's stipulation, not solely on the merits.

Recommended next steps

1. Get the petition tonight. Pull the IPR2026-00508 papers from PTAB Center / the AIA trial docket at https://ptacts.uspto.gov/ and the decisions at https://www.uspto.gov/patents/ptab/decisions. Until you have the grounds, claims challenged, and exhibit list, do not build a defense narrative — there is nothing to quote.
2. If you are Samsung (or a privy): your § 315(e)(2) exposure begins only at FWD; diarize ~2026-12-22 (PO preliminary response, 37 C.F.R. § 42.107(b)) and ~2027-03-22 (§ 314(b) institution deadline, ~6 months from filing). File a broad stipulation and honor it, given the Wilus line of attack.
3. If you are a different defendant being asserted on the '734 patent: you are not bound by IPR2026-00508 and no estoppel runs against you. You may file your own IPR, but calculate your own § 315(b) one-year bar from your service date, and consider whether to ride Samsung's record or file independently. Note the patent's apparent 2026-05-07 expiration limits you to past damages.
4. Pull the Fed. Cl. constructions. Colby v. United States (Fed. Cl. 2018) on "shield/shielding," "ON/OFF state," "responsive state," and "switch logic" is the only judicial construction of this family's vocabulary and is directly relevant to both the infringement theory (NFC hardware as an "inductive coupling"/"electronic switch") and to invalidity.
5. Confirm the expiration status independently. The "Expired – Lifetime / adjusted expiration 2026-05-07" entry is what the Google Patents record shows (derived from the 2006-05-07 non-provisional filing), and it matters enormously to the $500,000,000 demand. Verify PTA/PTE and any terminal disclaimer against the face of the granted patent before relying on it.

Explicit non-findings (stated as "not found," not as verified absence): no institution decision, no institution denial, no FWD, no settlement/termination, no Director Review request, no joinder, and no Federal Circuit appeal for IPR2026-00508 or for US 11,599,734. The petition is one day old; none of these could yet exist.

Contradictions and false positives I want on the record

• A different " '734 patent" is contaminating search results. One brief I reviewed argues that "the related '997 and '734 Patents, which issued in 2021 and 2024 respectively" are "significantly younger" than a '864 patent, in a dispute involving magnetic recording media, Western Digital, Seagate, Toshiba and Resonac. That is not this patent. US 11,599,734 issued 2023-03-07, is unrelated to magnetic media, and has nothing to do with those parties. Do not import that proceeding's reasoning.
• The Google Patents record I was given does not itself display the PTAB proceeding (it shows only the E.D. Tex. litigation and the Darts-IP "first worldwide family litigation" entry), consistent with indexing lag on a filing made one day before the fetch.
• Term/expiration. The record's "adjusted expiration 2026-05-07" implies the patent lapsed roughly four months before the IPR was filed. That does not bar the IPR (the Board reviews expired patents) but it does change the claim-construction standard (Phillips rather than the BRI/Phillips hybrid) and removes prospective relief from the litigation.
• Date-field inconsistency. The earlier section flagged a mismatch between an "April 26, 2026" prompt date and a 2026-09-23 fetch date. Working from today's date of 2026-09-23, the IPR was filed yesterday and everything above follows. If the operative date is different, the deadline arithmetic in this report shifts accordingly.

I'll research the assignment record for US 11,599,734. Let me start with the USPTO Assignment Center and cross-reference sources.

Let me dig into the specific assignment records and correspondent details.

Let me look for the specific assignment records with reel/frame numbers.

I hit the tool-call limit before I could pull the Assignment Center record directly, so I'm reporting what I could verify and flagging precisely what I could not. Note: this is a case where the honest answer includes gaps — I will not fill them with invented reel/frame numbers.

Ownership & Assignment Analysis — US 11,599,734 B2

Caveat up front (important): I was able to verify the Google Patents legal-event record for US 11,599,734, which lists two reassignment events. I could not, within this session, open the USPTO Assignment Center detail view to capture reel/frame numbers, execution dates, or the correspondent of record for either event. Those fields are therefore reported as not retrieved, not as absent.

Inventors

Unusual pattern to note: Colby is not merely the inventor — he is the founder/principal of the assignee. In Mynette Technologies, Inc. v. United States, Fed. Cl. 1:16-cv-01647 (filed Dec. 2016), Steven M. Colby and Mynette Technologies were co-plaintiffs, and the amended complaint attached the family patents US 7,924,156; 7,719,425; 9,524,458; and 9,569,777 as exhibits. That is direct record evidence that the "original assignee" is a Colby-controlled assertion vehicle, not an operating manufacturer. There is no evidence of the classic "all inventors departed within 12 months" pattern, because there is effectively only one inventor and he is the assignee principal.

Original assignee

Mynette Technologies, Inc. (Verdi, NV)

• Shipped a product embodying the claims? No evidence found. I found no product, no revenue, and no commercial embodiment tied to Mynette. The only activity surfaced is patent assertion: Mynette (with Colby) sued the U.S. government in the Court of Federal Claims over electronic passports (1:16-cv-01647), and Gemalto appears in related filings. That is a licensing/litigation posture, not a manufacturing one.
• Primary line of business: Patent holding/licensing of Steven Colby's RFID, electronic-passport, and switchable-RFID inventions (portfolio includes US 7,719,425; 7,924,156; 8,816,826; 9,569,777; 11,170,185; 11,599,734; 11,989,612; 12,039,396).
• Current status: Operating as a patent-holding entity (status not independently confirmed as of 2026-09-23); it assigned the '734 patent away on 2026-01-15 and, per the record, does not appear as current assignee. I found no bankruptcy, dissolution, or merger filing for Mynette. Treat "dissolved/bankrupt" as not found, not as verified negative.

Assignment timeline

Chronological list of the recorded events I could verify. Reel/frame and correspondent fields are unavailable in this session — flagged per entry.

• Execution date: not retrieved / recorded 2022-08-04 — Reel NOT RETRIEVED

  • Conveyance: ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)
  • Assignor: COLBY, STEVEN MICHAEL
  • Assignee: Mynette Technologies, Inc. (Verdi, NV)
  • Correspondent: not retrieved — flag: recurrence check not possible; this is the field most likely to reveal a repeat NPE-side recording attorney across the Colby/Mynette continuation family.
  • Context: Founder-to-company assignment — inventor transfers his own patent rights into his wholly controlled holding entity. This is the standard "original assignment" and does not by itself indicate an NPE transfer.

• Execution date: not retrieved (Google Patents records the reassignment as occurring 2026-01-15) / recorded 2026-01-15 — Reel NOT RETRIEVED

  • Conveyance: ASSIGNMENT OF ASSIGNOR'S INTEREST
  • Assignor: Mynette Technologies, Inc.
  • Assignee: SURECELL TRANSACTIONS, LLC (current assignee)
  • Correspondent: not retrieved — flag: recurrence check not possible.
  • Context: Transfer-to-asserter / monetization transfer — the patent left the original Colby entity and landed at a licensing entity ~4 weeks before SureCell filed suit against Samsung (2026-02-12). This is the load-bearing event for the NPE analysis.

No third assignment, security agreement, merger, change-of-name, or release was recorded in the material I reviewed. If the Assignment Center shows additional reels, my list is incomplete and should be updated.

NPE / troll-pattern signals

Verdict

NPE — moderate confidence.

The verified driver is the pre-litigation transfer: the patent moved from Mynette Technologies, Inc. to SURECELL TRANSACTIONS, LLC on 2026-01-15, ~4 weeks before SureCell filed the Samsung suit in E.D. Tex. on 2026-02-12 (2:26-cv-00106, $500M demand, six patents asserted including the '734). Both the original assignee (Colby's Mynette, a prior plaintiff in Mynette v. United States, Fed. Cl. 1:16-cv-01647) and the current assignee show no evidence of shipping a product, and trade press independently labels SureCell an NPE. I stop short of high confidence — and explicitly flag it — only because I could not retrieve the Assignment Center reel/frame data or the correspondent of record for either transfer, which is the evidence that would confirm the shell-entity and repeat-correspondent signals. A direct pull of reels for both events, plus a correspondent-name check across the Colby/Mynette continuation family, is the single highest-value next step.

Discrepancy flags vs. previously generated sections

• The prior section quoted the current date as April 26, 2026; the dataset/task date is 2026-09-23. I have used 2026-09-23.
• The prior section described the Justia/Google legal-events data but did not capture reel/frame or correspondent either. So the gap is consistent across the analysis — it is a source-access limitation, not a contradiction.
• Prior section lists the assignment to Surecell as 2026-01-15; I confirm that date from the Google Patents legal events, but I could not confirm the execution date versus the recording date (Google reports it as a reassignment event on that date). Do not treat 2026-01-15 as a verified execution date.

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

Let me pull the patent citation lists directly from the authoritative record pages.

Prior-Art Analysis — US 11,599,734 B2

"Methods of inductive communication in a cellular telephone"
App. 17/697,923 · filed 2022-03-18 · granted 2023-03-07 · inventor Steven Michael Colby · orig. assignee Mynette Technologies, Inc. · current assignee Surecell Transactions, LLC

⚠️ Critical threshold caveat (read first)

Before listing references, I have to be straight with you about a verification limit that carries through this entire deliverable:

1. I could not retrieve the complete, verbatim "(56) References Cited" list — i.e., the examiner-cited U.S. patent documents and non-patent literature printed on the face of the '734 patent — from an authoritative source in this session. What I did retrieve is a partial extraction from the Justia record for 11599734, which exposes only the beginning of the U.S.-patent-document list (one entry) and a chunk of the "Other Publications" (NPL) list. The Google Patents full text I was given is truncated before the claims and before the front-page references section.
2. I do not have verbatim claim text for the '734 patent (consistent with the earlier-generated summary). Therefore the § 102 columns below are provisional mappings based on the claim themes identified earlier (independent claims 1, 15, 23 per the SureCell v. Samsung complaint analysis) and on the specification's own "invention" definitions. They are not legal conclusions and should not be treated as anticipation findings.

Where I am uncertain about a reference's subject matter or date, I say so explicitly rather than fill the gap.

To get the authoritative, complete list, the sources to pull directly are:

• The granted-PDF front page (56) section: https://patentimages.storage.googleapis.com/.../US11599734.pdf
• USPTO PatentCenter file wrapper for 17/697,923 (IDS/892 forms list every examiner- and applicant-cited reference)
• Justia: https://patents.justia.com/patent/11599734

Part A — References I could positively confirm from the retrieved '734 record

A.1 Examiner/applicant-cited U.S. patent document (the one entry exposed)

Correction to the record: the earlier-generated summary of this patent did not surface any examiner-cited U.S. patent document. This Giesler '029 entry is new information relative to that summary and should be reconciled when the full list is pulled.

A.2 Non-patent literature (applicant-cited / "Other Publications"), from the Justia record

The NPL list above is not necessarily exhaustive — the retrieved text is a truncated window into the list.

Part B — References cited within the '734 specification (from the authoritative full text I was given)

These are not examiner citations; they are documents the specification expressly discusses or incorporates. They are nevertheless the most useful "each patent citation for 11599734" set that can be stated with confidence, because they come from the authoritative text rather than a third-party page.

Note on priority: the references listed on Google Patents as "Priority claimed from" (US 11/382,050; 11/382,052; 11/382,053; 11/382,264; 11/382,054; 11/382,265; 11/420,721; 11/458,620 → US 7,924,156; 12/577,209 → US 8,816,826; 14/660,825 → US 9,569,777; 16/186,543 → US 11,170,185) are family members / priority documents, not prior art. They should be excluded from any § 102 table.

Part C — Provisional § 102 mapping (heavily qualified)

Given (i) no verbatim claim text and (ii) an incomplete cited-reference list, I can only offer a thematic mapping. Independent claims identified earlier as 1, 15, and 23 are described (per the SureCell v. Samsung complaint analysis) as directed to performing a financial transaction with a point-of-sale device by changing an authentication/secure state of a cellular telephone and communicating financial information via an inductive coupling responsive to that state.

Part D — Explicit uncertainties / corrections to flag

1. New datum vs. earlier summary: an examiner/applicant-cited U.S. patent — US 6,424,029 (Giesler), Jul. 23, 2002 — is confirmed present in the '734 cited list. The earlier-generated summary reported no such entry; that summary was incomplete on this point and this should be treated as a correction/extension, not a contradiction of a verified fact.
2. The full (56) list is not reproduced here and may contain additional U.S. patents and foreign documents I could not see. Any conclusion that a given reference "is the most relevant prior art" would be premature until that list is pulled verbatim.
3. Claim text is still unverified. Do not cite the Part C mappings as anticipation findings; they are hypotheses keyed to a third-party complaint analysis, not the granted claims.
4. Giesler '029's subject matter is unverified in this session — I have deliberately not characterized it.
5. The Google Patents "prior art keywords" for '734 — state, switch, RFID tag, RFID, circuit — suggest the examiner's search focused on switchable-tag state logic, which is more consistent with the shielding/switchable RFID lineage than with the cellular-telephone inductive-communication claim set. That tension is worth resolving against the actual (56) list and the Office Actions in 17/697,923's file wrapper.

Recommended next step: open the USPTO PatentCenter file wrapper for application 17/697,923 and read the PTO-892 / SB-08 (IDS) forms and the examiner's reasons for allowance. Those documents give the definitive, literal citation list for this specific patent number — no similar-number substitution required.

I'll research the prior art cited in and relevant to US 11,599,734, focusing on the 2005-era references that would be available against its 2005/2006 priority date.

Obviousness Analysis — U.S. Patent No. 11,599,734 B2

35 U.S.C. § 103 (pre-AIA), "Methods of inductive communication in a cellular telephone"

Scope note and constraint I will not paper over. This analysis is built on the previously generated sections, which established that the verbatim granted claim text and abstract of the '734 patent were not retrieved; the independent claims (1, 15, 23) were reconstructed from the specification and a third-party complaint analysis. That limitation propagates directly into a §103 analysis, because obviousness is evaluated claim-by-claim, limitation-by-limitation. Everything below is therefore framed as a ground-by-ground template keyed to the reconstructed limitations, with explicit flags where I could not verify a reference's disclosure. This is an analyst's hypothetical, not a legal opinion and not an actual USPTO or court rejection.

Date discrepancy (flagged, consistent with prior sections). The task header says "Current Date: April 26, 2026." The authoritative dataset timestamp for this record is 2026-09-23, and the prior assignment section used it. I continue to use 2026-09-23 and flag the inconsistency rather than silently reconciling it. Note that a Korean trade-press item covering the Samsung suit is dated 2026-09-05 — later than the header date.

1. The threshold question that controls the entire prior-art universe: effective filing date

Before any reference can be applied, one must fix the §102/§103 critical date. The record (Google Patents; Justia) lists earliest priority 2005-05-06 and the non-provisional chain date 2006-05-07, with the application filed 2022-03-18. Unified Patents lists a 2005-05-05 priority for the sibling publication US 2007/0109101 A1 (application 11/458,620) — a one-day discrepancy versus Google's 2005-05-06 that I reproduce literally rather than correct.
https://portal.unifiedpatents.com/patents/patent/US-20070109101-A1 · https://patents.justia.com/patent/11599734

Two consequences:

(a) Pre-AIA governs. The chain predates March 16, 2013, so pre-AIA §102(a), (b), and (e) and pre-AIA §103(a) apply. Pre-AIA §103(c) may also disqualify art that is commonly owned or subject to a common obligation of assignment with the Colby/Mynette family.

(b) Priority is the swing factor. The '734 title and reconstructed claims are directed to inductive communication and financial data exchange by a cellular telephone — subjects that appear in the specification only in the "portable communication device" passages (cellular telephone / Blackberry / wireless PDA; RFID tag plus Bluetooth/WiFi/WiMAX/802.11/cellular; user-interface control of the tag; memory devices insertable into slots carrying multiple accounts; voice-recognition approval; two communication modes at different frequencies). If those passages supply §112 written-description support, the effective date is 2005–2006 and the prior art is confined to pre-2005 third-party art. If the claims require something the 2005 disclosure does not describe (e.g., a specific authentication-state architecture, a specific inductive-coupling handshake, or a POS-terminal interaction not described), the effective date slides toward 2022-03-18 — at which point the universe explodes to include sixteen years of third-party NFC/mobile-payment art and, critically, the many Colby-family publications themselves. This is the single highest-leverage issue in any validity challenge, and it is the issue on which I would advise the Samsung defendants to focus first. I flag that I could not perform the element-by-element §112 support mapping because the claim text was not retrieved.

Also flag: the previously generated sections noted the term is listed as "Expired – Lifetime; adjusted expiration 2026-05-07." If accurate, a §103 invalidity theory would in most fora be subsumed by a mootness/standing problem after that date — but for the pendency of E.D. Tex. 2:26-cv-00106 it remains live.

2. Person of ordinary skill in the art (POSITA)

For a 2005-era priority date in the contactless-payment/RFID field, a defensible POSITA definition is:

• a bachelor's degree in electrical engineering, computer engineering, or computer science (or equivalent), and
• 2–3 years of experience in one or more of: RFID/contactless integrated-circuit design, smart-card systems, or mobile/wireless handset hardware and protocol design;
• with additional experience substituting for formal education.

This POSITA is charged with knowledge of the ISO/IEC 14443 proximity-card family (Parts 1–4), ISO/IEC 7816 contact-card commands, the ECMA-340 / ISO 18092 NFC interface standards, and the commercially deployed Japanese mobile-wallet ecosystem (Sony FeliCa chips embedded in NTT DoCoMo handsets from 2004). Several of these are expressly of record: the Justia NPL listing for the family includes ISO/IEC 14443-1 through -4, ISO/IEC 7816 Parts 4/6/8/9, and multiple ICAO "Machine Readable Travel Documents" technical reports.
https://patents.justia.com/patent/11599734

That matters: a POSITA is presumed to know the standards, and a reference need not spell out what the standards already standardize (In re/MPEP line on industry standards as analogous art).

3. Claim construction of the load-bearing terms

The Mynette Technologies, Inc. v. United States claim-construction opinion (Fed. Cl. 1:16-cv-01647) construed five terms in the same-specification family, and those constructions are the starting point for the '734's corresponding terms:

https://www.courtlistener.com/opinion/[4527821](/patent/4527821)/mynette-technologies-inc-v-united-states/ · https://cases.justia.com/federal/district-courts/federal-claims/cofce/1:2016cv01647/33829/68/0.pdf

For the '734, the key constructions a court would need turn on "inductive coupling," "authentication state," and "financial information / account information." Note the specification supports both an inductive-coupling path and an RF (propagating-field) path: "the received signal is received through an inductive coupling or a non-RF antenna within Circuit 2250," and RFID Antenna 2240 "is optionally a dipole antenna," with low-frequency (coil/inductive) versus high-frequency (dipole/propagating) modes discussed. A claim reciting "inductive coupling" would therefore likely be read to require near-field magnetic coupling (ISO 14443 / FeliCa-type), not generic far-field RF — which narrows but does not save the claims, because inductive near-field payment was the dominant 2005 mobile-payment mode.

4. Prior-art inventory available against a 2005/2006 critical date

I separate what I verified in this session from what I could not verify and must be flagged rather than asserted.

4a. References confirmed to exist in the record (verified)

4b. Candidate references I could NOT verify in this session — flagged, do not cite as established

The searches surfaced only generic/adjacent NFC-charging and inductive-coupling patents (US 10,390,200 Hueber; US 9,577,718 Qualcomm; US 2003/0050011) — all too late or off-point for a 2005 critical date. I did not retrieve documentary prior art for the 2004–2005 commercial mobile-wallet deployments (Sony FeliCa-in-NTT DoCoMo handsets, JCB QUICPay, MasterCard PayPass, Visa payWave, Nokia NFC shell). These are almost certainly documentable (product literature, standards contributions, press releases) and would be powerful §102(b)/§103 evidence, but I have not verified any specific document, so I list them only as a research lead, not as references.

4c. References that are NOT available art (important trap)

The Colby/Mynette family itself — US 7,719,425; 7,924,156; 8,816,826; 9,524,458; 9,569,777; 11,170,185; 11,687,741; 11,989,612; 12,039,396; and the 2007/2008 pre-grant publications (US 2007/0200679–84, US 2007/0109101) — are the same inventive entity / same family / commonly owned, filed after the '734's own priority date. They therefore cannot be used as §102(a)/(b) art, are not §102(e) art against their own inventor, and are §103(c)-disqualified as commonly owned. A challenger who reaches for the family as prior art will fail. This is why the priority-date fight matters so much: if the '734 is pushed to a 2022 effective date, some of those same-family publications and the interim third-party art become available — but the §103(c) common-ownership bar may still knock out the family, leaving the third-party NFC/m-payment art as the workhorse.

5. Obviousness grounds

Below, each ground is a combination with an express motivation and reasonable expectation of success, per Graham v. John Deere and KSR Int'l v. Teleflex. Because the claim text is reconstructed, each ground maps to the reconstructed limitations [PREAMBLE], [A] inductive coupling with a POS/reader, [B] changing an authentication/security state of the phone, and [C] communicating financial/account information responsive to that state.

Ground 1 — Amtmann in view of ISO/IEC 14443 and ISO/IEC 7816

• Amtmann supplies: a cellular telephone / PDA that performs contactless (NFC) communication by inductive, antenna-to-antenna energy transfer; a voltage-supply stage that generates a second energy source from energy received from an external carrier signal; and an explicit switching between an active send mode (powered by the device's own battery) and a passive send mode (powered by the received field) — the latter being the classic inductive-coupling RFID tag behavior the '734 specification describes ("the RFID tag is configured to receive power from the power source of the communication device when the communication device is ON, and to generate power from a received inductive or RF signal when the communication device is off").
• ISO/IEC 14443 supplies the standardized inductive-coupling interface and anti-collision/initialization protocol (and is of record in this family).
• ISO/IEC 7816-4/8/9 supplies the key/authentication-based access architecture that maps onto the '734's "change the ON/OFF state in response to comparison with a key" and onto the reconstructed "changing the authentication state of the cellular telephone."
• Motivation to combine: A POSITA in 2005 would combine these because (i) a phone already carrying a 13.56 MHz NFC chipset is the obvious platform on which to run an ISO 14443-compliant payment application; (ii) standards-compliant, battery-independent operation (passive mode) is directly demanded by the POS use case (the terminal must be able to read the phone even when the phone's radio stack is asleep or the screen is off); and (iii) security gating of the payment function by a key/authentication step (ISO 7816-style) is the standard, predictable way to prevent unauthorized reads.
• Reasonable expectation of success: high — each element is a known, off-the-shelf building block, and the combination is the mechanical assembly of a known handset chipset with a known payment application.
• Likely claim-construction fight for the patentee: that "authentication state of the cellular telephone" means the phone's own (e.g., operating-system / user-unlock) state, not an RFID-protocol authentication state. If so, Ground 1 must be supplemented with phone-side security art (Ground 2).

Ground 2 — Ground 1 + phone-side user-authentication art (access code / biometric / unlock gating a handset function)

The '734 specification itself recites: "the user interface of the communication device is configured to receive an access code before the RFID tag is detectable… prior to receiving the access code the RFID tag may be disabled from sending radio frequency signals," and "voice recognition authentication may be required before an RFID tag is activated," and "the RFID tag is inactive unless a cell phone is opened." These admissions teach the very "changing an authentication state" limitation and can be used as applicant-admitted art (they are admissions of what was known/contemplated in the field, useful to show the limitation is not novel or non-obvious in combination).

• Motivation: user-authentication gating of a wireless payment function is motivated by the well-known security problem of unauthorized/phantom reads of contactless credentials — a problem the specification itself acknowledges ("minimizing the risk of 'skimming' and 'eavesdropping'," and the BAC discussion in Mynette v. United States regarding the '156 patent: "utilizing what is known as Basic Access Control (BAC) to receive information stored on e-passports while minimizing the risk of 'skimming' and 'eavesdropping'").
• Anticipation note: if a single third-party reference discloses phone + inductive-payment + user-auth unlock gating, that is §102 anticipation, not §103. The FeliCa/DoCoMo and PayPass/payWave ecosystems are the place to look.

Ground 3 — US 6,424,029 (Giesler) as primary, in view of the inductive-coupling and phone-authentication secondary references

• Applicant cited US 6,424,029 on the face of the '734 patent. Its content was not retrieved here, so this ground is contingent: if '029 discloses a portable/handheld device that wirelessly exchanges data with a terminal (the likely subject matter of a 2002 Giesler patent in this class), then '029 supplies [A] and the preamble, and Ground 1/2 secondaries supply [B] and [C].
• Why this matters procedurally: a reference cited by the applicant and applied in the same or substantially the same manner is (i) hard to disparage and (ii) does not raise the "non-analogous art" and "teaching away" defenses as sharply. Recommendation: pull US 6,424,029 and its family immediately — it is the cheapest path to a defensible primary reference.

Ground 4 — The "multiple stored accounts / user selection" sub-limitations

The '734 specification discloses "a plurality of slots configured to receive memory having credit card data," "the user interface may then be used to select which account (e.g., the first bank or second bank accounts) should be used for a particular transaction," and "activating a first switch may result in a transaction being debited from a first account and activating a second switch may result in a transaction being debited from a second account." If any claim recites multi-account storage/selection:

• Combine Grounds 1–2 with pre-2005 multi-application smart-card art (a "multi-application" card holding several payment applications on one chip, with selection by the terminal or by the cardholder, was a mature concept in the ISO 7816-4 command architecture and in EMV-era payment art). Motivation: card consolidation is the defining consumer benefit of a phone-as-wallet, expressly recited in the specification.
• Note the previously generated patent summary records a same-family pre-grant publication titled "RFID Device Including Multiple Active Modes" (US 2007/0200682 A1), and family members "US 2007/0200679–84" — i.e., the multi-mode/multi-account concept is a Colby-family staple, corroborating that the concept was considered routine in this field by 2005–2007.

Ground 5 — The "periodic/state-memory ON-OFF" limitation (if any independent claim recites it)

Reconstructed claim [B]/[C] and the specification's "state memory" architecture ("an input configured to receive data… an output… a state memory configured to store an ON/OFF state… a key memory… switch logic…") map onto ordinary RFID chip-access-control state machines documented in ISO/IEC 7816-4/-9 and in the ISO 14443-3/-4 anticollision/protocol layers — all of record in this family. The court's construction of "ON/OFF state" (Mynette v. United States) confirms the term means only "a switchable status that includes an OFF state and at least one ON state," with data non-transmissible in OFF — a construction that is broad and therefore easy to meet with conventional chip state logic.

6. §102 anticipation notes (where a single reference may suffice)

Under pre-AIA §102(b), a printed publication or public use in the U.S. more than one year before the 2005/2006 filing — i.e., before ~2004-05-06/2005-05-07 — that discloses a cellular telephone inductively coupling with a POS device to transmit financial information, gated by a phone authentication state, would anticipate rather than merely render obvious. Candidates to test (unverified here): JCB QUICPay (2004) and the NTT DoCoMo FeliCa mobile-wallet rollout (2004) as §102(a)/(b) public uses/publications, and the ISO/IEC 14443 standards as printed publications. I flag that I did not verify a specific anticipatory document and will not assert one.

7. Secondary considerations (objective indicia)

On the record generated so far, the evidence of nexus is weak to nonexistent, which helps the obviousness case:

• No commercial embodiment: the prior assignment analysis found no product, no revenue, and no commercial embodiment tied to Mynette or SureCell; the asserted patent moved from Mynette to SureCell Transactions LLC on 2026-01-15, ~4 weeks before the 2026-02-12 Samsung complaint. Absent a practicing product there is no presumption of nexus, so evidence of "industry praise / long-felt need" tied to third-party phones (Samsung Pay/Wallet) would not ordinarily inure to the patentee.
• No unexpected results are described in the specification; the '734's advantages (convenience, shielding, security) are the very problems the cited art addresses.
• The only colorable secondary-consideration theme would be industry adoption of NFC payment — but that adoption is attributable to the third-party reference references themselves (the standards and the manufacturers), which undercuts rather than supports non-obviousness.

8. Where the patentee's best rebuttals lie (steelman, for balance)

1. Priority + §112 / written description. If the challenged claim limitations are supported by the 2005–2006 disclosure, the challenger's art must be pre-2005, and the strongest commercial prior art (FeliCa, PayPass, payWave) may fall after the critical date. The patentee will fight hard to hold the 2005 date.
2. "Authentication state of the cellular telephone" construction. If construed narrowly to the handset's own security/user state (OS unlock, SIM/device PIN, voice biometric), the challenger must find art that gates an inductive financial transmission on that state. The specification's own "access code before the RFID tag is detectable" and "voice recognition authentication before an RFID tag is activated" admissions cut both ways — they are admissions, but they also show the applicant contemplated the limitation as its own.
3. "Inductive coupling" as a narrowing limitation. A court could read "inductive coupling" to exclude far-field/propagating RF, narrowing the claim to true near-field magnetic coupling; the challenger must then land art squarely on ISO 14443/FeliCa-type coupling.
4. §103(c) / common ownership will knock out the family references the challenger may be tempted to use — so the challenger must build the case from third-party art only.

9. Bottom line

• Framework: pre-AIA §103(a); POSITA = EE/CE/CS degree + 2–3 yrs in RFID/contactless/mobile hardware; critical date ~2005-05-06/2006-05-07 (subject to the §112 priority test, which is the pivotal issue).
• Strongest verified foundation: Amtmann (cell phone/PDA doing NFC contactless communication with battery-powered and field-powered modes) in view of ISO/IEC 14443 and ISO/IEC 7816, with US 6,424,029 (Giesler) held in reserve as the applicant-cited primary reference.
• Motivation/expectation: strong — each element is an off-the-shelf 2005 building block, and the combination is the predictable assembly of a known handset NFC chipset with a known standards-based payment application; the specification's own "portable communication device," "access code," "voice recognition," and "multiple accounts/slots" passages supply both support and admissions.
• Principal weakness of the analysis: the verbatim claims were never retrieved, so the grounds are keyed to reconstructed limitations and must be re-mapped claim-by-claim before anyone relies on them.
• Highest-value next steps: (1) pull the granted claims from the USPTO PatentCenter file for 17/697,923 or the granted PDF; (2) pull US 6,424,029 (Giesler) and the Amtmann patent in full and verify dates/disclosure; (3) document the 2004–2005 FeliCa/DoCoMo, PayPass, payWave, and Nokia NFC-shell prior art as §102(b)/§103 evidence; (4) run the §112 written-description support mapping to test the 2005 priority claim; and (5) check PTAB for any post-February-2026 IPR/PGR petition naming SureCell Transactions LLC.

Discrepancy flags vs. previously generated sections

• Date: prior sections used 2026-09-23; the task header says April 26, 2026. I used 2026-09-23 and flag the conflict rather than reconcile it.
• No contradiction found with the prior patent-summary, litigation, or assignment sections — this §103 analysis depends on and inherits their verified findings (assignees, litigation posture, "expired" status, missing claim text) and does not contradict any of them.
• One inherited caveat made explicit: the prior sections correctly refused to treat the reconstructed claims as quotations. That refusal is more consequential here than anywhere else in the report, because an obviousness ground is only as good as the claim limitation it is mapped to.
