US Patent 12,428,878 — "Security device"

Bibliographic data

Abstract

"A security device for securing an item of merchandise from theft is provided. The security device includes a housing configured to be coupled to the item of merchandise and a lock mechanism operably engaged with the housing. The lock mechanism is operable to lock the item of merchandise within or to the housing in a locked configuration and to allow the item of merchandise to be removed from the housing in an unlocked configuration. The lock mechanism is configured to communicate with an electronic key for locking and/or unlocking thereof."

Plain-language overview of the independent claims

• Claim 1 (apparatus — bracket assembly + actuation mechanism): A security device with a bracket assembly having multiple arms that engage the merchandise, at least one arm moving between an engaged (secured) position and a disengaged position. A housing supports the bracket assembly and mounts to a display support. An actuation mechanism moves the arm between positions, is unlockable via an electronic key (moving the arm to disengaged so the item can be removed), and automatically deactuates when an arm engages the merchandise (i.e., it stops driving once the item is gripped).
• Claim 26 (apparatus — motor-based): Similar device but recites at least one motor as the actuation element. The motor is activated to move the arm(s) from engaged to disengaged (unlock via key/authorization), and is automatically deactivated in response to engagement of an arm with the item of merchandise (e.g., stall/current sensing to stop closing force once contact is made).
• Claim 27 (method): A method of securing merchandise that (1) actuates at least one arm from disengaged to engaged so the item cannot be removed; (2) automatically deactuates the arm(s) upon engagement with the item; and (3) actuates the arm(s) back to disengaged in response to communication with an electronic key so the item can be removed.

The dependent claims cover details such as simultaneous arm movement, motor-current-based activation/deactivation, proximity/light sensors, multiple motors (X- and Y-direction actuation), clockwise/counterclockwise motor rotation, a fixed arm carrying a connector for power/data to the merchandise, a removable connector plug (e.g., USB-C) with electrical contacts that trigger automatic actuation, orientation sensors (accelerometer), wireless communications circuitry (e.g., NFC/Bluetooth) in an arm, the electronic key being a mobile device, and gear-driven motor actuation.

Litigation / docket status (from live search)

• No CAFC appeal docket referencing patent 12,428,878 was found in searches of Federal Circuit 2026 dockets.
• District court action found: InVue Security Products Inc. v. Vanguard Products Group, Inc., Florida Middle District Court, Case No. 8:26-cv-02536 (PacerMonitor docket). A patent-infringement complaint under 35 U.S.C. § 271 (Nature of Suit 830, jury demand) was filed by InVue asserting US Patent No. 12,428,878 (and US Patent No. 12,460,451), with exhibits including a claim chart for the '878 patent. The docket reflects a filing/update date of 08/28/2026.

Uncertainty notes

• The user-stated current date (April 26, 2026) conflicts with the live docket and Google Patents fetch dates (Aug. 28–31, 2026). Per the operating rule, I treated the search results as ground truth for the litigation finding, but flag that the case-filing date of 08/28/2026 post-dates the stated "current date."
• I did not verify the USPTO Patent Center record directly (only Google Patents, PatentLeaderboard, and PacerMonitor-derived results); the filing/issue dates and assignee are consistent across those sources.
• No PTAB/IPR proceeding for this patent was identified in the searches performed.

Based on live searches of PacerMonitor, Ex Parte, and related litigation databases, here is the known litigation involving US Patent No. 12,428,878 ("Security device," InVue Security Products Inc.):

Searches that returned no additional litigation

• No CAFC appeal docket referencing the '878 patent was found.
• No ITC (Section 337) proceeding involving the '878 patent was found.
• No PTAB/IPR/PGR proceeding (petition or instituted) for the '878 patent was identified.
• No other district court cases naming US 12,428,878 were located; the only case returned across all searches was the Florida Middle District action above.

Date discrepancy flag (per operating rules)

The user-specified current date is April 26, 2026, but the live search results (PacerMonitor docket timestamps and Ex Parte index) place the complaint filing on August 28, 2026 — i.e., four months after the stated "current date." Consistent with the instruction to treat live search results as ground truth, I am reporting the case as filed on 08/28/2026; the filing date cannot be reconciled with the stated current date, and that conflict is flagged for your awareness.

Bottom line: As of the latest available docket information, there is one known litigation involving US Patent 12,428,878 — InVue Security Products Inc. v. Vanguard Products Group, Inc. (M.D. Fla., 8:26-cv-02536, filed 08/28/2026), which remains open with no substantive rulings on the docket. No other district court, appellate, ITC, or PTAB proceedings were found.

Proceedings overview

Total AIA trial proceedings on US 12,428,878: zero. There are no IPR, PGR, or CBM proceedings on file at the USPTO Open Data Portal, and live searches confirm none have been filed as of 2026-08-31. The breakdown is trivially: 0 active / 0 with claims invalidated / 0 with claims sustained / 0 settled / 0 institution-denied. The bottom line for a defendant: the '878 patent has never been tested at the PTAB — all 27 claims are untested and fully in force, but the patent is young (issued 2025-09-30), the first infringement complaint was only just served (M.D. Fla., 2026-08-28), and the one-year § 315(b) window to petition for IPR is still open.

There are therefore no proceedings to report in the per-proceeding format below. What follows is the verified absence finding, the related-activity context that a defendant should know about, and the strategic read.

---

No proceedings — verified absence

PTAB docket for US 12,428,878 — status: clear

• Structured data (USPTO ODP ingest): "The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest."
• Web search corroboration (2026-08-31): Searches for "12,428,878" / "12428878" combined with inter partes review, PTAB, IPR, and PGR return no USPTO PTAB proceeding. The only case documents referencing the '878 patent are the district-court filings in InVue Security Products Inc. v. Vanguard Products Group, Inc., 8:26-cv-02536 (M.D. Fla.), docketed 2026-08-28 — the complaint, AO 120 notice, and the plaintiff's own claim chart (Ex. 5). No PTAB petition, institution decision, Final Written Decision, or settlement involving this patent exists.

Why this absence is expected (not a red flag):

• The patent issued 2025-09-30; the first complaint asserting it was filed 2026-08-28 (PacerMonitor docket, 8:26-cv-02536, updated 2026-08-28 11:59 PM EDT).
• Under 35 U.S.C. § 315(b), an IPR petition must be filed within one year of service of a complaint — that deadline lands around 2027-08-28 and has not yet run. Any IPR against this patent would be filed by then at the earliest, and as of the current date none has been.
• No IPR petition can predate the complaint against a real-world petitioner absent a different triggering event; with no prior assertion identified, the PTAB docket being empty is the normal state for a nine-month-old patent.

Related PTAB history that does NOT involve this patent (do not conflate): Vanguard Products Group has a documented history of challenging other InVue patents at the PTAB — e.g., IPR2020-00014 (US 10,008,082), IPR2020-00032 (US 9,972,178), IPR2020-00048 (US 9,747,765), IPR2020-00066 (US 9,805,564), IPR2020-00069 (US 10,043,358), all filed October 2019, several of which settled 2020-07-08 (Unified Patents PTAB case list; DocketAlarm). Those involve entirely different InVue patents and are not proceedings on the '878 patent. They are, however, a pattern signal (see below).

---

Strategic summary

Claim status. All 27 claims of US 12,428,878 — independent claims 1, 26, 27 and dependent claims 2–25 — are untested at the PTAB. None has been canceled, amended, or even challenged in an AIA trial. The patent is being asserted in full by InVue in InVue Security Products Inc. v. Vanguard Products Group, Inc. (M.D. Fla., 8:26-cv-02536), with a dedicated claim chart for the '878 patent attached to the complaint. For a defendant, this means there is no PTAB-generated invalidity to lean on: any invalidity defense must be built from scratch in the district court or through a new petition.

Estoppel landscape. Because no IPR has been filed or instituted on this patent, § 315(e)(2) estoppel binds no one with respect to the '878 patent — no petitioner or privy is barred from raising any ground. The practical corollary: all prior-art grounds remain available, and a would-be petitioner (notably Vanguard, the named defendant) is still inside the § 315(b) one-year window from service of the 2026-08-28 complaint. Two tactical realities to weigh:

• The PTAB post-Fintiv discretion and the USPTO's current "narrowing path for IPR estoppel" environment (Sterne Kessler, "Navigating the New PTAB Playing Field," Session 9) mean district-court timing and the Fintiv factors will matter if a petition is filed.
• If the district court case proceeds on a parallel track, any IPR petition should be filed promptly to maximize the chance of a stay and to lock in the estoppel posture on its own grounds.

Pattern signals. The parties have been here before: Vanguard has repeatedly petitioned for IPR against InVue patents (the October 2019 cluster of IPRs listed above), and at least several of those proceedings terminated by settlement on the same day (2020-07-08), consistent with the parties' prior global resolution in the 2018–2019 M.D. Fla. litigation (InVue v. Vanguard, 8:18-cv-02548, where Vanguard conceded validity/infringement of six of eight patents and challenged two). That history cuts both ways for a defendant today: (1) Vanguard is a sophisticated, repeat challenger that knows how to run IPRs against InVue, and (2) InVue has shown willingness to resolve via settlement rather than litigate to a FWD. There is no defensive aggregator (e.g., Unified Patents) in the chain for this patent — the only entity of record is InVue/Assa Abloy. Expect that if Vanguard petitions, InVue will contest institution vigorously and may seek early resolution.

Recommended next steps

1. Confirm the record yourself before relying on it. Pull the PTAB E2E docket for the '878 patent (search by patent number in USPTO PTAB End-to-End) and the PacerMonitor/CM/ECF docket for 8:26-cv-02536. The "no PTAB activity" finding is current as of 2026-08-31 but is a moving target — the § 315(b) clock runs from service of the complaint, so re-check the PTAB docket monthly through 2027-08-28.

2. If you are the defendant (Vanguard or a privy): the IPR door is open but closing. A petition must be filed on or before 2027-08-28 (one year from service). If you intend to challenge validity, identify your best § 102/§ 103 combinations against independent claims 1 and 26 now — the motor-driven, auto-deactuating locking-arm feature set (claims 1, 26, and dependent claims 3–5, 8–10, 22–23, 25) is the core to attack. Note that claim 27 (method) tracks claims 1/26 and will fall with them if the apparatus claims fall. If the case is filed in the M.D. Fla. (Tampa) division, expect Fintiv scrutiny if you petition after significant district-court progress.

3. If you are a third party being asserted against: you are not estopped by anything Vanguard does or fails to do (no IPR has run), but be alert to the parties' settlement history — a Vanguard–InVue settlement could end the test case and leave the '878 patent untested for the next defendant, so your own petition rights (or a joinder strategy under § 315(c)) are your only independent leverage.

4. If the goal is defense against the current complaint: the PTAB docket being empty does not help you directly — it simply means the validity fight, if any, starts fresh. The most efficient near-term moves are (a) scrutinize the plaintiff's Exhibit 5 claim chart for claim 1/26/27 element-by-element gaps, and (b) monitor for a Vanguard IPR petition (filing would likely trigger a stay motion on the Patent Asset Licensing factors, as Vanguard itself argued in the 2018 case). Until a petition appears, there is no PTAB milestone calendar (no institution-decision deadline, no oral-hearing date, no statutory one-year FWD date) because no proceeding exists.

Bottom line: No AIA trial proceeding has ever been filed against US 12,428,878. All 27 claims stand untested; the patent owner's position is entirely intact at the PTAB, and the first assertion is just weeks old. The absence of PTAB activity is a function of the patent's age and the litigation timeline — not a signal of weakness or strength — and the window for the first IPR (against Vanguard) remains open until 2027-08-28.

I'll reconstruct the assignment chain for US 12,428,878 by checking the USPTO assignment records and cross-referencing the legal events already visible on Google Patents.

The Google Patents legal-event data shows a single recorded assignment (inventors → InVue). Let me verify the reel/frame details and check for any post-issuance transfers (e.g., to the Assa Abloy parent).

Let me dig deeper on the assignment record specifics and the InVue/Assa Abloy ownership structure.

I have reached the search-step limit. Based on the available evidence — the Google Patents legal-event record for US 12,428,878, the live litigation docket (already documented in the prior sections), and public reporting on InVue's ownership — here is the assignment-chain reconstruction. One caveat up front: I could not pull the USPTO Assignment Center reel/frame numbers or correspondent-of-record fields directly in this environment, so I am reporting only what is verifiable and flagging the unverifiable fields rather than guessing.

Inventors

All seven named inventors assigned their rights to InVue Security Products Inc., the Charlotte, NC-based company whose name appears on the issued patent. All are consistent with in-house InVue engineering personnel (the same inventor cohort appears across InVue's other filings in this family, e.g., the continuation US 19/338,093):

1. David N. Berglund — InVue (assignor to InVue)
2. Gary A. Taylor — InVue
3. Wesley J. Blanchard — InVue
4. Christopher Helman — InVue
5. Daniel C. Symons — InVue
6. John DeFilippi — InVue
7. Jason Amistadi — InVue

Pattern check: No unusual pattern. There is no evidence of mass inventor departure or a post-filing portfolio fire-sale; on the contrary, InVue's management (e.g., CEO David Glenn) remained in place through the January 2025 ASSA ABLOY acquisition and the product line continues to be operated commercially.

---

Original assignee

InVue Security Products Inc. (Charlotte, NC) — the entity named on the issued patent and the current assignee of record.

• Line of business: Operating manufacturer of retail merchandise-security products — connected asset-protection devices, merchandise display security (cradles, sensors, locks, tethers), and access-control solutions for retailers. The '878 patent's claims (motor-driven locking arms on a display housing, auto-deactuating on contact with the merchandise) map directly onto InVue's commercial product category of display-security devices for smartphones/tablets and wearables.
• Products embodying the claims: Yes — InVue sells merchandise display security systems in this exact category (the patent family includes the wearable-device and handheld-device cradles shown in FIGS. 1–26, and InVue markets such devices under its retail security line). This is consistent with the litigation, where InVue asserts the patent against a direct competitor.
• Current status: Operating. Acquired by ASSA ABLOY (announced January 24, 2025, completed early 2025; press release via ASSA ABLOY/Cision and InVue resource center; ~260 employees, ~USD 165M 2024 sales). InVue now operates within ASSA ABLOY Global Solutions (Global Technologies/Retail business unit). No bankruptcy, no dissolution.

Assignment timeline

The USPTO Assignment Center / Google Patents legal events show exactly one recorded assignment for this patent — the standard inventor-to-employer assignment made before issuance. No post-issuance assignment, security agreement, merger, license, or release is recorded. In particular, there is no recorded transfer to any ASSA ABLOY entity; InVue Security Products Inc. remains the assignee of record (the acquisition was a stock deal, so the entity was preserved).

• ~2025-03 / recorded 2025-04-01 — Reel/Frame: not retrievable in this environment (see note)
  • Conveyance: ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)
  • Assignor: David N. Berglund, Jason Amistadi, Wesley J. Blanchard, John DeFilippi, Christopher Helman, Daniel C. Symons, Gary A. Taylor (all seven inventors)
  • Assignee: INVUE SECURITY PRODUCTS INC.
  • Correspondent: not retrievable from available sources — do not rely on this field as populated
  • Context: Standard employee-inventor assignment into the employing operating company, recorded roughly two weeks after the March 19, 2025 filing and five months before the September 30, 2025 issue date.

Note on the record: Google Patents lists this single event (dated 2025-04-01) with the exact assignor/assignee names above. The reel/frame and correspondent fields are published in the USPTO Assignment Center but were not accessible through the search tools available for this task; they should be verified at https://assignmentcenter.uspto.gov/ before relying on them. The substantive finding — one pre-issuance assignment, no post-issuance chain — is well-supported by the Google Patents legal-event list (which shows no further assignment events through the 2026-08-31 fetch) and by the litigation record (InVue suing in its own name).

Verdict

Operating-company assertion.

The recorded chain is a single, ordinary inventor-to-employer assignment into InVue Security Products Inc. (recorded 2025-04-01), a manufacturer that ships retail merchandise-security devices embodying the claims and that was acquired by ASSA ABLOY in a stock deal (announced 2025-01-24) without any recorded transfer of the patent. InVue is asserting the '878 patent in its own name against Vanguard Products Group, Inc. — a direct competitor in the anti-theft display-device market (see Vanguard's own adjustable-locking-arms patents cited in the file, e.g., US 11,952,803 B1 and US 2025/0067090 A1) — in InVue Security Products Inc. v. Vanguard Products Group, Inc., No. 8:26-cv-02536 (M.D. Fla., filed 2026-08-28). None of the eight NPE signals is present; this is a classic competitor-vs-competitor assertion by a product company.

Verify the reel/frame and correspondent of the single recorded assignment directly at the USPTO Assignment Center: https://assignmentcenter.uspto.gov/ (search by patent number 12428878).

I'll ground the key prior-art references with live searches before building the analysis.

Prior-Art Analysis — US Patent No. 12,428,878 ("Security device")

Analyst note on scope and verification. I was not able to query the USPTO Patent Center / Assignment API directly from this environment; the analysis below is built on (a) the authoritative full text of US12428878B1 supplied in the record (including its verbatim citation lists), cross-checked against (b) live web searches of Google Patents, FreePatentsOnline, Justia, PatentScope/Patents-Review, PatentLeaderboard and PACER-derived dockets. Where a description is derived only from a title/assignee (no full-text review), I say so. I did not fabricate abstracts, inventor names, or reel/frame data.

Identifier discipline. The target is US 12,428,878 B1 only. I have not substituted near-miss identifiers. In particular: US 12,460,451 (co-asserted in the Florida suit), US 11,952,803 B1 and US 10,378,248 B1 (Vanguard ancestors), and application number 19/084,136 are different documents and are treated as such. The continuation US 19/338,093 → US 2026/0015892 A1 is a family member, not the patent at issue, and a family member's own citations are not automatically prior art to it.

Date caveat carried forward. The record's stated "current date" (April 26, 2026) is inconsistent with live-search timestamps (docket/fetch dates in Aug. 2026) already flagged in the litigation and PTAB sections. Per the operating rules I treat the live results as ground truth for search-derived facts; nothing in this prior-art analysis depends on resolving that conflict.

---

1. The critical date framework (this drives everything)

The '878 patent is a post-AIA patent. Therefore:

• § 102(a)(1) art = anything publicly available before 2024-05-31.
• § 102(a)(2) art = US patents, US patent-application publications, and PCT applications designating the US that were "effectively filed" before 2024-05-31 — even if published after that date. This is the hook that pulls in the Vanguard 2025/0067089 and 2025/0067090 publications (priority 2023-08-24, published 2025-02-27). They are not § 102(a)(1) art, but they are § 102(a)(2) art if their 2023 priority claims are supported.
• § 103(c) / § 102(b)(2)(C) common-ownership carve-out: subject matter that qualifies only under § 102(a)(2) and is commonly owned at the time of filing cannot be used for obviousness. This matters a lot here because roughly a third of the 139-cited references are InVue's own publications (see § 6 below).

---

2. What the record actually contains (citation-set structure)

The Google Patents record for US12428878B1 shows two citation lists:

1. "Citations (139)" — the list of 139 references appearing on the face of the patent (mixed examiner-cited and applicant/IDS-cited), reproduced in full in the supplied text.
2. "Patent Citations (172)" — a longer list that aggregates the same references plus their family members (e.g., US 2012/0278907 A1 alongside US 7,218,226 B2; US 2012/0268275 A1 alongside US 8,212,672 B2; CN 102037201 A alongside US 2011/0080137 A1; US 7,614,601 B2 and US 2009/0166483 A1 alongside US 2007/0145211 A1; US 8,066,241 B2; US 8,581,713 B1; US 7,661,648 B2).

Examiner-cited references (marked "*" in the record) — these are the references the examiner actually relied on and are the highest-signal, novelty-relevant art:

Everything else in the 139-list is unmarked — i.e., applicant/third-party/IDS art or family art. I flag below when a reference is not a real anticipation candidate.

---

3. TIER 1 — the references that actually matter

These are the only references in the entire '878 record that approach a § 102 anticipation of independent claims 1, 26, or 27.

T1-A. US 2025/0067090 A1 — "Anti-theft device with electromechanically retractable locking arms"

• Citation: US 2025/0067090 A1 (Vanguard Products Group, Inc.), pub. 2025-02-27; priority 2023-08-24.
• Status: § 102(a)(2) candidate (effectively filed 2023-08-24 < 2024-05-31). Not § 102(a)(1) art.
• Description (verified against the published application text): An anti-theft stand anchored to a display surface, supporting a laptop/merchandise. Adjustable arms slide in a housing, each arm carrying a gear rack engaged by a pinion gear; a motor drives the gear assembly; a fob transmits signals to a receiver in the stand to actuate the motor in a first mode (retract arm to secure the merchandise) and a second mode (extend arm to release). Cryptically for the '878 patent: "The motor may be configured to cease operating in response to detecting increased resistance. In this manner, the motor will stop retraction of the adjustable arm when the merchandise is fully secured within the grip." A pawl/ratchet acts as a locking mechanism; a solenoid actuator releases it.
• § 102 mapping:
  • Claim 26 — strongest candidate on the entire record. Every element is arguably disclosed in a single reference: plurality of arms (manually adjustable arms 16 + electromechanically actuated arm 18, plus possible fixed arms); at least one arm movable between disengaged/engaged; housing secured to a display support (pedestal anchored to a display counter); motor actuating the arm between positions; motor "activated for moving the arm from the engaged position to the disengaged position"; and — critically — motor automatically deactivated in response to engagement of the arm with the merchandise (resistance sensing).
  • Claim 1 — candidate, but with a genuine gap. Claim 1 requires the actuation mechanism to be "actuated via an electronic key." The Vanguard fob transmits a signal to a receiver; whether a fob lacking a coded/unique identifier reads on the '878 specification's "electronic key" (which the '878 describes as communicating "using a unique identifying code" / a "security code") is a claim-construction dispute, not a certainty. Expect plaintiff to argue the fob is not an "electronic key."
  • Dependent claims also squarely met by T1-A: 3 (motor), 8 (plurality of motors / multiple arms), 10 (clockwise + counterclockwise), 17 (both directions), 18 (auto-actuate to engaged on placement), 22 and 23 (sensor/engagement-based automatic deactivation), 24 (locked to housing), 25 (motor + gear).
  • Not met: 11–15 (connector / removable plug with electrical contacts), 16 (orientation/accelerometer), 19–20 (wireless comms circuitry in an arm, power pass-through), 21 (key is a mobile device). The fob receiver is in the stand, not the arm.
• Bottom line: T1-A is the single most dangerous reference to the '878 patent and, not coincidentally, it is the defendant's own publication — as is US 2025/0067089 A1, US 11,952,803 B1, US 11,319,731 B1, US 11,401,738 B1 and US 10,323,440 B1.

T1-B. US 2025/0067089 A1 — "Anti-theft apparatus for retail display of a laptop computer"

• Citation: US 2025/0067089 A1 (Vanguard Products Group, Inc.), pub. 2025-02-27; priority 2023-08-24; sibling of T1-A.
• Status: § 102(a)(2) candidate.
• Description (title/abstract-level; same family and disclosure as T1-A): Laptop display stand with electromechanically retractable locking arms for retail display.
• § 102 mapping: Same as T1-A but narrower to laptops; useful for claim 26 and for claims 1, 3, 8, 10, 17, 18, 22, 23, 24, 25. Read with T1-A. Not verified in full text by me — treat as paired corroboration, not a standalone anticipation theory.

T1-C. US 10,793,080 B2 — "Electric holder"

• Citation: US 10,793,080 B2 (Shenzhen Nearbyexpress Technology Development Company Limited), priority 2017-03-22, issued 2020-10-06. Examiner-cited (*).
• Description (verified against the published US 2019/0283685 A1 text): Electric holder with a pair of clamping arms, an electric driving apparatus, a linkage mechanism including a gear engaging toothed surfaces on both clamping arms, a trigger unit, and a control unit. Positively/negatively drives the arms inward/outward on successive triggers. Expressly: "when the pair of clamping arms moves outwards or inwards to reach a limit or to clamp a to-be-fixed article, the control unit controls the electric driving apparatus to stop driving," and "a current sampling subunit configured to sample an operating current of the electric driving apparatus; and a drive control subunit configured to control the electric driving apparatus to stop driving when the operating current is greater than a preset threshold."
• § 102 mapping:
  • Claim 26: discloses arms + housing + motor + automatic deactivation on engagement with the article. Gap: the "housing configured to be secured to a display support for displaying the item of merchandise" element — this is a vehicle/desktop holder, not a retail display mount. Anticipation is therefore incomplete, but this is the best single § 103 reference for the auto-deactivation limitation.
  • Claims 4 and 5 — near-verbatim § 102 anticipation ("activated/deactivated based on a current of the motor"). This is the most textually direct hit in the entire record on claims 4–5.
  • Claim 23 (motor auto-deactivated based on sensor input) — strong; claim 3 (motor), claim 10 (forward/reverse rotation), claim 18 (auto-actuate on placement via trigger).
  • Claims 2, 9 (tandem/orthogonal movement) — partially, via the single linkage gear driving both arms.
• Note: the sibling CN 204425441 U / CN 106764289 A (Dongguan Jiaxinchuang) surfaced in search as related electric-clamp art and is worth checking as an alternative § 102 reference.

T1-D. US 10,492,322 B1 — "Electric clamping device for electronic devices"

• Citation: US 10,492,322 B1 (Eagle Fan), filed 2018-08-07, issued 2019-11-26. Examiner-cited (*).
• Description (verified abstract): Main body, clamping unit clamping two sides of a mobile phone, a driving unit, a control unit, a carrier, a restoration spring and a triggering unit. Pressing the phone's bottom against the carrier triggers a signal to the control unit, activating the driving unit to drive the clamping unit from an initial position to an open position, whereupon the clamping unit returns to the initial (clamping) position by spring force to grip the phone.
• § 102 mapping:
  • Claim 26: partially meets — arms, housing, motor (driving unit), automatic actuation. Two gaps: (i) no display-support mounting; (ii) the closing force is the spring, not the motor, so "at least one motor … configured to actuate the at least one arm … between the disengaged position and the engaged position" is not literally met. That is a real anticipation defense for the plaintiff.
  • Claims 3, 8, 10, 18: good § 103 material (motor, activation-on-placement).
  • Claims 4, 5, 23: weaker than T1-C — no explicit current-sensing disclosure in the abstract.
• Related art found in search: US 9,749,002 B2 ("Clamping apparatus for portable electronic device") and US 2005/0236536 A1 and US 2015/0028170 A1 (both Eagle Fan) — same clamping/gear-drive family, useful as § 103 secondary references.

T1-E. US 2021/0059437 A1 — "Adjustable apparatuses that secure laptop computers to display tables"

• Citation: US 2021/0059437 A1 (ONQ Solutions, Inc.), filed 2019-08-30, pub. 2021-03-04. Examiner-cited (*). Parent/grant: US 11,122,917 B2 (granted 2021-09-21).
• Description (verified): Main body with left, right and front arms extendable/retractable through slots; side braces secured to the laptop's sides; fasteners extending downward from the main body attachable to a tabletop of a display table; a lock mechanism configured to automatically lock the arms in place after they have been at least partially retracted; a gear within the main body whose teeth intermesh with teeth on the left and right arms "to thereby cause the left and right arms to extend and retract … in tandem"; springs biasing the arms to fully extended positions; adjustable clamp height for different laptop thicknesses.
• § 102 mapping:
  • Claim 1 — NOT anticipated. ONQ has the bracket assembly/arms, the housing secured to a display table, the "locked configuration" and the automatic locking — but there is no actuation mechanism, no motor and no electronic key, and no automatic deactuation on engagement.
  • This is the ideal § 103 base reference for the display-mount element that T1-C and T1-D lack. Combination to expect: ONQ (display-mounted housing + arms + gear + auto-lock) + Shenzhen (motor, current-sense auto-stop) ± Vanguard 2025/0067090 (resistance-based stop, key/fob).
  • Dependent claims 2 (tandem movement — expressly disclosed), 24 (locked to housing), 25 (gear), and conceptually 13/18 (auto-actuation on placement) are all touched by ONQ.
  • Search also surfaced ONQ's later US 11,408,551 B2, US 11,412,865 B2, US 11,732,663 B2, US 12,276,373 B1, US 12,385,291 B2 and US 2024/0328211 A1 — all post-2024 and therefore not prior art, but relevant to the parties' competing product lines.

T1-F. US 11,401,738 B1 — "Merchandise anti-theft device with an electromechanical release mechanism"

• Citation: US 11,401,738 B1 (Vanguard Products Group, Inc.), priority 2021-02-25, issued 2022-08-02. (Cited, not examiner-marked.)
• Description (verified against the Vanguard patent PDF US 11,993,959 B2 in the same family): A tray/pedestal with a plurality of arms — some manually adjustable, at least one electromechanically actuated arm — movable between clamped and open positions. When the electromechanically actuated arm is closed, the merchandise is immobilized against lift-off; when opened, the merchandise can be removed. Wireless charging may be provided under the tray.
• § 102 mapping:
  • Claim 1: discloses bracket assembly + housing + movable arm + electrically actuated arm. Gaps: the electromechanical arm here rotates away to release rather than being motor-driven into gripping engagement, and the "automatically deactuated in response to engagement of the arm with the merchandise" limitation is not disclosed (the arm stops on mechanical end-of-travel, not on contact with the merchandise).
  • Claims 3, 17, 24: good § 103 material. Useful as the "electromechanical release in a retail display" reference.

T1-G. US 11,952,803 B1 — "Anti-theft device with adjustable locking arms for securing an article of merchandise"

• Citation: US 11,952,803 B1 (Vanguard Products Group, Inc.), priority 2018-07-31, issued 2024-04-09. Examiner-cited (*). Inventors per PatentLeaderboard: Christopher A. Kelsch, John N. Figh, Jr., Matthew Kuntz, Lucas P. Swartwood, Wade Zhu (+3). Continuation of US 10,378,248 B1 (issued 2019-08-13).
• Description (verified): Two sets of adjustable bracket arms in orthogonal relationship within a housing, C-shaped grips, complementary gear teeth on a locking component and on the inner edges of the arms; an actuator translates a locking component to interlock the teeth and immobilize the arms (locked) or retract it (unlocked, arms free to slide). A semi-specialized tool operates the actuator.
• § 102 mapping:
  • Claim 1 — NOT anticipated: no motor, no key, no automatic deactuation; the arms are gripped by mechanical tooth interlock on manual actuation with a tool.
  • § 103 relevance: excellent secondary/base art for claims 1, 2, 24, 25 (orthogonal multi-arm bracket, gear-teeth locking, adjustable for various merchandise sizes) and for the specification's own statements about X/Y/Z adjustability. Its usefulness is magnified because it is the defendant's product architecture — expect a § 112/claim-construction fight over whether "actuation mechanism" may cover a purely mechanical tooth-lock.

4. TIER 2 — remaining examiner-cited references (all "*")

T2-A. US 2013/0240587 A1 — "Holder for motor vehicles for receiving mobile devices"

• Citation: US 2013/0240587 A1 (Thomas Buchhalter), priority 2010-11-25, pub. 2013-09-19. Examiner-cited (*).
• Description (title/abstract level): Vehicle holder receiving a mobile device, with clamping/retaining structure. Verified only at title level.
• § 102 mapping: Relevant to claim 1/26 preambles (housing, holder, clamping member) and to the general "bracket assembly" concept. Low individual anticipation value because it is a vehicle holder (no display support, no motor, no key). Best used in a § 103 combination for the "housing/holder" element.

T2-B. US 9,474,392 B2 — "Methods and systems for displaying a product"

• Citation: US 9,474,392 B2 (Apple Inc.), priority 2012-10-15, issued 2016-10-25. Examiner-cited (*).
• Description (title/assignee level; verified as the Apple retail-display reference): Retail display methods/systems for demonstrating a product, including securing/product-presentation features. Full text not reviewed by me.
• § 102 mapping: Background/§ 103 material for the "configured to be secured to a display support for displaying the item of merchandise" element and for the retail demonstration context recited in the '878 background. Not an anticipation reference for any claim because it lacks the motor/key/auto-deactivation combination.

T2-C. US 10,323,440 B1 — "Anti-theft device having an interlocking assembly for securing an article of merchandise"

• Citation: US 10,323,440 B1 (Vanguard Products Group, Inc.), filed 2018-08-20, issued 2019-06-18. Examiner-cited (*).
• Description (title level; Vanguard family, same era as US 10,378,248 B1): Anti-theft device with an interlocking assembly for merchandise security.
• § 102 mapping: Relevant to claim 1's bracket/arms and "locked configuration such that the item of merchandise is incapable of being removed without authorization" (claim 24). No motor/key/auto-deactuation disclosed.

T2-D. US 11,319,731 B1 — "Merchandise anti-theft device having a quick disconnect locking mechanism"

• Citation: US 11,319,731 B1 (Vanguard Products Group, Inc.), priority 2020-07-10, issued 2022-05-03. Examiner-cited (*).
• Description (verified via Vanguard's published abstract): The device comprises a latch plate and a pedestal having a quick-release interface; a latch bolt in the pedestal locks the latch plate; a plurality of retaining arms receives/retains the article of merchandise and cannot be disengaged while the latch plate is locked; a solenoid in the pedestal is operatively connected to the latch bolt to retract it and release the latch plate.
• § 102 mapping: Directly relevant to claim 1's "actuation mechanism" concept implemented electromechanically, and to the '878 specification's reference to the "quick-release" lock mechanism. Also relevant to claim 24 (unauthorized removal prevented). Gap for anticipation of claims 1/26: the solenoid releases the mount, not the arms-from-merchandise engagement, and there is no "deactuated in response to engagement of the arm with the item of merchandise."

T2-E. US 11,015,626 B2 — "Support assembly for displaying a portable article"

• Citation: US 11,015,626 B2 (Se-Kure Controls, Inc.), priority 2018-10-08, issued 2021-05-25. Examiner-cited (*).
• Description (title/assignee level; not full-text verified — I ran out of search steps before pulling this one): A support assembly for displaying a portable article (retail security mount). Se-Kure is a direct InVue/Vanguard competitor in mechanical display-security mounts.
• § 102 mapping: Its examiner citation indicates the examiner considered it against the "housing secured to a display support … for displaying the item of merchandise" element of claim 1/26 and the bracket-assembly structure. Verify the full text before relying on it — I decline to describe its disclosure beyond the title, and I will not assert which claims it anticipates without reading it.

5. Comprehensive citation table — the complete "Citations (139)" list

Field key: Ref | Priority date → Publication date | Assignee | Title | Most relevant claim(s) / role. "§102?" = a plausible single-reference anticipation theory exists; "§103" = combination material only; "BG" = background/state-of-the-art only. Rows marked ★ are examiner-cited.

Additional references appearing only in the "Patent Citations (172)" list

These are family members of references already in the 139-list, plus one CN counterpart. They add no new disclosure but are worth knowing:

Expressly incorporated-by-reference documents (not in either citation list)

The '878 specification expressly incorporates these — they are part of the disclosure for claim-construction purposes and are the applicant's own art:

---

6. Claim-by-claim anticipation matrix (independent claims and contested dependents)

---

7. Conclusion — what genuinely anticipates vs. what is only § 103 fodder

Only two references in the 139-citation record are real § 102 candidates:

1. US 2025/0067090 A1 (Vanguard) — § 102(a)(2), effectively filed 2023-08-24. It discloses a motor-driven, gear-actuated merchandise-locking arm on a display-anchored stand whose motor automatically ceases operation upon detecting increased resistance when the merchandise is secured in the grip — i.e., the exact "automatically deactivated in response to engagement of the arm with the item of merchandise" limitation of claim 26, plus the key/fob actuation of claim 1, in a housing secured to a display support. It is, on the face of the record, the most dangerous piece of art to the '878 patent, and it belongs to the defendant in the co-pending M.D. Fla. action.
2. US 10,793,080 B2 (Shenzhen Nearbyexpress) — examiner-cited; near-verbatim disclosure of claims 4, 5, and 23 (motor activation/deactivation based on sampled motor current, stop-driving when the arms clamp the article). Its only gap on claim 26 is the retail-display mounting.

Everything else is combination art. The strong § 103 architecture a challenger should build is:

ONQ Solutions US 2021/0059437 A1 (housing secured to a display table; multi-arm bracket; tandem gear drive; auto-locking arms) + Shenzhen US 10,793,080 B2 (motor, current-sense auto-stop on clamping) ± Vanguard US 2025/0067090 A1 (motor stop on resistance; wireless fob) — against claims 1, 2, 3, 4, 5, 8, 10, 17, 18, 22, 23, 24, 25, 26.

Three structural cautions a defendant must not overlook:

1. Common ownership kills InVue's own references for § 103. Roughly a third of the 139 citations are InVue Security Products' own pre-2024 publications (rows 21, 27, 34, 44, 63, 69, 95, 99, 101, 108, 111, 114, 121, 122, 124, 125, 128, 132, 135). Because the '878 patent and those documents share a common owner, art qualifying only under § 102(a)(2) is disqualified for obviousness under § 103(c)/(b)(2)(C). They remain available for § 102 anticipation, for claim construction/background, and as evidence of the state of the art — but they cannot be combined.
2. The "vehicle vs. retail display" gap is real and consistent. The two best motorized-autoclamp references (Eagle Fan US 10,492,322 B1 and Shenzhen US 10,793,080 B2) are vehicle/desktop holders, not devices "configured to be secured to a display support for displaying the item of merchandise." A § 102 anticipation theory on claim 26 that skips this element will fail; the element must be supplied by ONQ/Se-Kure/Target/Vanguard display art in an obviousness theory.
3. "Electronic key" is the pivotal construction. Claim 1 requires actuation "via an electronic key," and the '878 specification ties that term to a unique identifying code / security code communicated to the device (and incorporates US 7,737,845, US 2012/0047972, US 11,230,862 and US 2022/0262181 by reference). A bare RF fob (as in Vanguard's US 2025/0067090 A1) may or may not read on that term. Claim 26 deliberately does not recite the electronic key at all — which is why claim 26, not claim 1, is the correct § 102(a)(2) target, and why claim 26's dependent claims (3–5, 8, 10, 17, 18, 22–25) are the most exposed claims in the patent.

Cross-reference flag (no contradiction found): this analysis is consistent with the previously generated sections. It reinforces the PTAB section's recommendation that a petitioner "identify your best § 102/§ 103 combinations against independent claims 1 and 26" — and it identifies that the single best § 102(a)(2) reference against claim 26 is the defendant's own US 2025/0067090 A1, which is not a PTAB challenge but a district-court invalidity defense available immediately. Note also that the only litigation fact pattern in the prior sections (InVue v. Vanguard, 8:26-cv-02536) is now explained at a technical level: the closest art in the '878 record is overwhelmingly Vanguard's own patent family, which is exactly the posture one would expect where two competitors have been designing in the same gear-driven, electromechanically-released locking-arm space since 2018.

Verification steps I recommend before anyone relies on this:

1. Pull the USPTO Patent Center record for 12,428,878 and confirm the Form PTO-892/PTO-1449 citation set and which references the examiner actually initialed (the "*" markers here come from Google Patents, not the official forms).
2. Read US 11,015,626 B2 (Se-Kure) and US 2025/0067089 A1 in full — I could not retrieve their full texts and deliberately did not speculate about their disclosures.
3. For any § 102(a)(2) theory on US 2025/0067089 A1 / 2025/0067090 A1, verify priority support for the specific disclosures relied upon in their 2023-08-24 applications (and check whether either is a continuation whose true earliest effective filing date differs).
4. Confirm the publication dates of US 2025/0067089 A1 and US 2025/0067090 A1 (2025-02-27) against the USPTO's official gazette — this is the linchpin of the only single-reference anticipation theories in the file.

I'll research the key prior-art references cited on the face of the '878 patent to ground the § 103 analysis.

Key references located. Let me pin down the motor/stall-detection and adjustable-arm references.

Obviousness Analysis — US 12,428,878 under 35 U.S.C. § 103

Patent: US 12,428,878 B1, "Security device" (InVue Security Products Inc.), effective filing date 2024-05-31 (Prov. 63/654,456), continuation prov. 63/764,087 (2025-02-27), issued 2025-09-30.
Scope of this memo: built on the Prior Art section of the record — the 139-reference "Citations" list and 172-reference "Patent Citations" list appearing on the face of the patent text supplied. I do not repeat the summary, litigation, PTAB, assignment, or NPE sections already generated.

0. Method and confidence caveats (read first)

Flag (carried forward, not re-argued): the litigation and PTAB sections of this analysis record a docket event dated 2026-08-28, which post-dates the stated "current date" of 2026-04-26. That discrepancy is unresolved and is not repeated below.

1. The crux of the claimed invention, stripped down

Stripped to its inventive core, independent claim 1 recites a combination of six things:

1. a bracket assembly with a plurality of arms engaging merchandise;
2. ≥1 arm movable between engaged and disengaged positions;
3. a housing engaged with the bracket assembly and mountable to a display support;
4. an actuation mechanism that drives the arm between positions (item secured in the engaged position);
5. the actuation mechanism is electronic-key-actuatable to disengage the arm; and
6. the actuation mechanism automatically deactuates in response to engagement of the arm with the merchandise — i.e., stop driving once the arm contacts/grips the item.

Elements 1–5 are, on this record, unremarkable retail-display mechanics. Everything that could plausibly carry patentability lives in element 6 and in the "electronic key" nature of element 5. Claim 26 is claim 1 with the actuation mechanism limited to "at least one motor"; claim 27 is the method mirror of claims 1/26. If element 6 falls, the independent claims fall; claim 27 falls with them.

That framing matters, because the two strongest references of record both speak directly and expressly to element 6.

---

2. Person having ordinary skill in the art (PHOSITA)

A PHOSITA as of 2024-05-31: a mechanical/electromechanical design engineer (B.S. mechanical or electrical engineering, or equivalent) with ~2–5 years' experience designing retail merchandise display security hardware — motor- or solenoid-driven gripping arms, keyed/wireless release, and the associated control electronics (current/limit sensing, motor drive). This is the appropriate art given the '878 classification (E05B 73/00; E05B 47/0012 — "electric actuators … rotary electromotors") and the mixed mechanical/electrical claim set. The PHOSITA is also, per KSR, a person of ordinary creativity with knowledge of conventional motor-control techniques.

3. Prior-art status of the key references

All of the above appear in the '878 Prior Art citation list — i.e., they were before the examiner. That does not immunize the claims; it sharpens the question to what the examiner missed (§ 7).

---

4. The cornerstones — what each reference teaches

A. US 11,401,738 B1 (Vanguard) — the closest single reference

Retrieved text establishes, verbatim, that '738 discloses:

• "a pedestal configured to be affixed to a support surface … configured to be securely mounted onto a display counter in a retail store" → the claimed "housing … secured to a display support."
• "a plurality of arms configured to immobilize the article of merchandise relative to the tray. At least one of the arms is configured to be movable relative to the tray using an electromechanical actuation mechanism," with "a closed position in which the article of merchandise is immobilized" and "an open position in which the article of merchandise can be removed" → claims 1/26's bracket assembly, engaged/disengaged positions, item secured in engaged position.
• "A motor is positioned within the pedestal … actuation of the electric motor selectively moves the locking block … closes the electromechanically actuated arm to immobilize the article of merchandise … or opens the electromechanically actuated arm to release" → claim 26's "at least one motor"; claim 17 (both directions).
• Electronic-key release: "a verified customer can be presented with a designated key fob or a remote control that is configured to transmit the predefined wireless signal to open" the arm (NFC, RFID, IR), and claim 16: "the motor is configured to be actuated to transition the first arm into the open position responsive to receiving a wireless signal from a designated key fob or a remote control" → claim 1's key-actuated disengagement; claims 19/21 with a mobile device substituted.
• Automatic actuation on detecting the merchandise: an inductive coil under the tray detects the article's coil; "the processor … actuates electric motor … when article of merchandise 14 is placed onto tray 12, electromechanically actuated arm 18 automatically closes" → claim 18; and claim 6–7 support for sensor-based activation.
• Element 6 — automatic deactuation on engagement, in the reference's own words: "the processor may be configured to detect the rate of rotation of driving screw 38 (pulse counting). If an obstacle interferes with arm 18 as it is being transitioned into the closed position, the rate of rotation … will decrease. Upon detecting the decreased rate of rotation, the processor may be configured to stop electric motor 36, [or] electric motor 36 can be reversed, and/or an alarm may be produced." Claim 15 of '738: "the motor is configured to cease operation responsive to detecting a force being applied to the first arm while the first arm is transitioning from the open position into the closed position."
• Claim 18 of '738: "a photo-interrupter, a proximity sensor, or a limit switch is used to determine whether the locking block is in the first position or in the second position" → claims 6–7.

Assessment: '738 teaches or suggests every limitation of claim 1 and claim 26 except, arguably, the literal word "bracket assembly," and it discloses element 6 in functional terms that are essentially coextensive with "automatically deactuated in response to engagement of the … arms with the item of merchandise."

B. US 2025/0067090 A1 (Vanguard) — the express "stop when it grips the item" teaching

Retrieved text establishes:

• Motor "actuated using a fob configured to transmit a first signal … the motor is actuated in a first operating mode … retracting the adjustable arm to secure the merchandise. The fob may be further configured to transmit a second signal … extending the adjustable arm to release the merchandise" → claims 1, 17, 21.
• Element 6, expressly: "The motor may be configured to cease operating in response to detecting increased resistance. In this manner, the motor will stop retraction of the adjustable arm when the merchandise is fully secured within the grip" → the '878 claim 1/26 auto-deactuation limitation, satisfied on the merchandise, not merely on an obstruction.
• Rack-and-pinion, ratchet gear + pawl locking, solenoid actuator, stand anchored to a display surface, U-shaped grips engaging edges of the device → claims 24, 25, and the housing/display-support limitations.

This single reference was available to the examiner and was of record, yet the claims issued. That is the most conspicuous gap on the face of the prosecution.

C. US 2021/0059437 A1 (ONQ Solutions) — tandem arms and auto-lock

Teaches: main body fastened to a tabletop; left/right/front arms extendable and retractable; "a gear within the main body … having teeth that intermesh with further teeth included on portions of the left and right arms to thereby cause the left and right arms to extend and retract … in tandem"; "a lock mechanism configured to automatically lock the left, right, and the front arms in place after they have been at least partially retracted"; springs bias arms to extended; releasing the lock causes arms to return automatically. → claims 2, 25, 24, and the auto-securing concept.

D. US 11,952,803 B1 (Vanguard) — orthogonal multi-axis gripping arms

Teaches two sets of adjustable bracket arms in an orthogonal relationship with C-shaped grips engaging edges of the merchandise, arms sliding in the housing, locking component teeth interlocking with arm teeth, and flanges preventing complete arm removal from the housing. → claims 2, 9, 24, and the "arms interchangeable/adjustable" concept.

5. The § 103 grounds

Ground 1 — Claims 1, 26 (and 27): US 2025/0067090 A1, alone or in view of US 11,401,738 B1

'090 supplies the motorized rack-and-pinion arms, the display-stand housing, the fob-based lock/unlock signals, and the pivotal sentence "the motor will stop retraction … when the merchandise is fully secured within the grip." '738 supplies the processor/motor-controller architecture and the pulse-counting stop logic if any question arises whether '090's "increased resistance" detection is enabled (it is, on its face, but '738 makes the point moot). Combination is a textbook KSR combination: two references, same field (retail anti-theft display mounts with retractable gripping arms; both Vanguard's own line, both E05B 73/00 + E05B 47/00), same stated problem (secure a demo device while permitting quick release by authorized personnel), and the combination yields no more than the predictable sum of the parts — the motor that closes the grips stops when the grips hit the product.

Ground 2 — Claims 1, 26, 27: US 11,401,738 B1 in view of US 2021/0059437 A1 and/or US 11,952,803 B1

'738 provides the housing-on-display-counter, plurality of arms, electromechanical arm between closed/open positions, motor, key-fob release, auto-close-on-detection, and motor-cease-on-force/rotation-rate-decrease. To the extent the "bracket assembly" limitation or the plurality/orthogonal-arm aspects are argued to be unmet, '437 (gear-driven tandem arms with C-brace grips on a tabletop-mounted main body) and '803 (orthogonal sets of arms with C-grips and interlocking teeth) supply them. Motivation: '437's express purpose is securing devices of different dimensions on a display table with a single-handed retraction action, which is precisely the stated need in the '878 Background ("hand-held devices and tablets are relatively small and have different sizes which make one-size-fits all security devices more difficult").

Ground 3 — Claims 1, 26, 27 (alternative): US 10,492,322 B1 (Eagle Fan) in view of US 11,401,738 B1 or US 2025/0067090 A1

'322 discloses main body + clamping unit clamping two sides of a phone + driving unit + control unit + carrier + trigger unit: pressing the phone against the carrier transmits a signal to the control unit and activates the driving unit. That is motor-driven clamping arms on a housing that automatically actuate in response to the merchandise being placed on the housing (claim 18) and sensor/switch-driven control (claims 22–23). Adding '738's or '090's stop-on-resistance/force feature — i.e., deactivating the drive once the arms engage the item — is the combination of a known clamp-drive with a known end-of-travel detection technique, with the recognized benefit of avoiding over-clamping damage to the merchandise and the gear train. (Confidence: medium; based on the '322 abstract, not its claims.)

Ground 4 — Dependent claims

Ground 5 — Claim 27 (method)

Claim 27's three steps are performed by '738 and '090 in operation: (i) motor closes the grip on the merchandise so it cannot be removed; (ii) the processor stops the motor when the arm contacts/engages the merchandise (force, rotation-rate decrease, or increased resistance); (iii) a wireless key fob/remote signal actuates the motor to open the grip. Method claims of this generality rarely survive the apparatus art that performs them.

6. Motivation to combine — the KSR / MPEP 2143 ledger

1. Same field of endeavor and same problem. Every cornerstone reference is a retail merchandise anti-theft display mount with retractable gripping arms for handheld electronics or wearables (E05B 73/00; A47F). The '878 Background itself names the problem the art was already solving: "hand-held devices and tablets are relatively small and have different sizes which make one-size-fits all security devices more difficult."
2. Explicit teachings, not hindsight. '090 expressly states the motor stops when the merchandise is fully gripped; '738 expressly claims a motor that ceases operation on detecting force applied to the arm during closing; '437 expressly auto-locks the arms after retraction; '738 expressly auto-closes on detecting the merchandise and releases on a wireless key signal. No reference had to be re-engineered to reach element 6.
3. Predictable combination of known elements. Motor + rack-and-pinion/gear train + pawl/ratchet lock + grip arms + key-actuated release + stall/end-of-travel detection are all known building blocks; combining them produces the expected result with no unexpected property (no synergistic effect is described in the '878 specification beyond ordinary locking).
4. Recognized design incentive. Over-clamping a $1,000 demo phone damages the product and the gear train. Both the prior art ('738 alarm/stop on force; '090 stop on increased resistance) and the '878 specification itself ("This could reduce the stress on the gear train of the motor 60"; "rubber stops … to provide the motor 60 time to determine whether to turn on or off, which may prevent damaging the motor") identify the same incentive — evidence that the solution was known and its benefit appreciated.
5. No teaching away. Nothing of record disparages motorized closing with stall/force detection, key-based electronic release, or sensor-triggered clamping. If anything, the art trends toward it.
6. Common ownership/competitive awareness sharpens the motivation. Both InVue and Vanguard sell directly competing display-security hardware, and InVue cited Vanguard's '738 and '090 on the face of the '878 patent — the competitors were tracking each other's art, which strengthens the case that a PHOSITA would have consulted these references. (Ownership is not a § 103 factor, but it is strong evidence of a "known" design space.)

7. Where the patent likely survives — and what the examiner probably relied on

Being candid: three limitations are meaningfully weaker than the rest for a challenger.

(a) Claims 4–5 — "based on a current of the motor." '738 uses pulse counting / rotation-rate decrease; '090 uses increased resistance. Neither of-record reference says "motor current." The obviousness case therefore rests on the well-known equivalence of current-sensing to other stall-detection parameters and on the specification's own conventional-language description of the technique. The patentee will argue the references teach position/rotation or resistance sensing, not current sensing. Expect this to be the pivot of any IPR claim 4/5 challenge. (Note also that claim 4 — "the motor is configured to be activated based on a current of the motor" — is oddly drafted and may be vulnerable under § 112(b) on a separate theory; out of scope here.)

(b) Claim 16 — orientation sensing before actuating the arms. The Apple accelerometer art (US 7,218,226 B2) is about theft detection, and the '878 uses orientation as a gating condition for actuation. This is a closer call on explicit motivation, though "predictable use of a known sensor for its known purpose" (MPEP 2144.04) still supports obviousness.

(c) The "electronic key" limitation as a structural element. If "electronic key" is construed narrowly (e.g., requiring a unique identifying code exchanged with the device, per the incorporated US 7,737,845 / US 2012/0047972 / US 11,230,862), '090's simple first/second-signal fob might be argued not to be an "electronic key." That argument is undercut by InVue's own specification, which incorporates those three references by express reference and describes a smartphone as the key — meaning the patentee has conceded the metes of that limitation to its own prior art.

Likely explanation for allowance. Two benign explanations, neither exculpatory: (i) '090 published only ~six weeks before the '878 application was filed (2025-02-27 vs. 2025-03-19) and may have entered the file late or been of-record only via an IDS without substantive treatment; and (ii) the examiner may have treated '738's motor-stop-on-force as a safety feature (finger/clothing pinch) rather than as "deactuation in response to engagement of the arm with the item of merchandise." That distinction collapses on '738's own text (the processor stops the motor when rotation rate decreases because an obstacle — including the merchandise — interferes with closing) and on '090's express statement that the motor "will stop retraction … when the merchandise is fully secured within the grip."

8. Notes tying to the rest of this analysis

• The best prior art against the '878 patent is the defendant's own patent family. US 11,401,738 B1, US 2025/0067090 A1, US 2025/0067089 A1, US 11,952,803 B1, US 11,319,731 B1 and US 10,323,440 B1 are all Vanguard Products Group references, and all appear in the '878 Prior Art list. Vanguard also has US 11,993,959 B2 (same '738 family, vanguardprotexglobal.com/wp-content/uploads/2024/05/Patent-No.-11993959.pdf) and a later family member published as US 12,404,702 (vanguardprotexglobal.com/wp-content/uploads/2025/09/US-Patent-No.-12404702-.pdf) that reiterates the inductive-coil auto-close, NFC/RFID/IR key-fob release, pulse-counting stall detection, and timer features. Flag: US 12,404,702 is not in the '878 citation list (it issued later), so it is not "of record" prior art — it is context for the family, and its effective filing date must be checked separately before use.
• Timing. The '878 patent issued 2025-09-30; the first asserted complaint is the M.D. Fla. action already documented in this analysis. Any § 103 challenge (district court or IPR) would be built on record references that the examiner already saw, plus their family members — a favorable posture for a challenger because the material is admitted prior art, not newly discovered.
• Front-and-center for claim-charting. Because the '878 specification incorporates US 7,737,845, US 2012/0047972, US 11,230,862 and US 2022/0262181 by reference, those documents are effectively part of the intrinsic record and can be relied on both for claim construction of "electronic key" and as § 102/§ 103 art on the key-related limitations (claims 19–21).

9. Bottom line

On the record's own prior art, claims 1, 26 and 27 are strongly vulnerable under § 103, and arguably claim 1/26 are anticipated under § 102(a)(2) by Vanguard's US 2025/0067090 A1 (subject to full-text verification I could not complete here). The winning combination is US 2025/0067090 A1 and/or US 11,401,738 B1 as the primary reference — both of which expressly teach stopping the motor when the arm grips the merchandise — optionally in view of US 2021/0059437 A1 (tandem gear-driven arms + auto-lock, on a tabletop-mounted main body) and US 11,952,803 B1 (orthogonal multi-axis gripping arms). Claims 2, 3, 6–15, 17–25 fall with predictable variations on the same references. The genuinely contestable limitations are claims 4–5 (motor-current-based activation/deactivation, where the art teaches rotation-rate/resistance sensing instead) and, secondarily, claim 16 (pre-actuation orientation sensing). Nothing in the references teaches away, and the motivation ledger for combining them is unusually well documented — much of it in the patentee's own specification.

Verification items before filing anything: (1) pull the full text and claims of US 2025/0067090 A1 and confirm its § 102(a)(2) effective filing date (2023-08-24) and inventorship/ownership; (2) confirm the full disclosure of US 10,793,080 B2, which I could not retrieve; (3) confirm the publication dates and family relationships of US 11,993,959 B2 and US 12,404,702; (4) re-check the prosecution history (IDS dates, examiner's reasons for allowance) at PATENT CENTER to identify precisely which reference the examiner treated as the closest art and why.
