US Patent 9,173,322 — Summary

Bibliographic data

Abstract (verbatim): "Preferred embodiments provide a cooling system for an electronic display. A constricted convection plate is used to force cooling air against a posterior surface of the electronic display. Fans may be used to propel or pull air between the constricted convection plate and the rear surface of an electronic display. A refrigeration unit or thermoelectric module may be employed to cool or heat the air traveling through the constricted convection channel. Some embodiments include a closed loop which extracts heat (or adds heat) to the front display surface."

Independent claims (claims 1, 4, and 9; 16 claims total)

• Claim 1 — System for cooling a housed display. An electronic display having a posterior display surface is contained within a housing. A constricted convection plate is placed posterior to (behind) the display surface, covering the majority of it. At least one bracket connects the display surface to the plate, and a fan is placed to draw ambient air between the plate and the rear posterior (i.e., through the narrow channel defined between them). In plain terms: a rear cover plate mounted close behind the display creates a thin airflow channel, and a fan pulls outside air through that channel to cool the display's backside.

• Claim 4 — LCD with LED backlight (apparatus). A liquid crystal display comprising a liquid crystal stack and a backlight assembly behind it. The backlight has a PCB with front and back sides, LEDs mounted on the front side, and a posterior surface on the rear side of the PCB. A constricted convection plate sits behind and substantially parallel to that posterior PCB surface, with a fan positioned to draw air between the plate and the posterior surface. In plain terms: the claimed cooling is applied directly to the rear metal/PCB surface of an LED backlight.

• Claim 9 — Means-plus-function system. An electronic display having a front display surface and a posterior surface where no electronics are mounted. A constricted convection plate behind the posterior surface covers a majority of it, and there is a means for forcing air between the plate and the posterior surface. In plain terms: this claim covers the same rear-plate cooling concept but is not limited to a fan per se — any air-forcing means (e.g., fans, blowers) is covered, on a display whose rear surface carries no electronics.

CAFC 2026 docket activity (directly on this patent)

• Manufacturing Resources International, Inc. v. Squires, No. 24-2228 (companion 24-2229), U.S. Court of Appeals for the Federal Circuit, origin: PTO (PTAB IPR appeal). Nonprecedential opinion issued March 31, 2026 (2026 WL 879712; Judge Taranto; judgment entered same date). The court affirmed the PTAB's final written decisions in IPRs (including IPR2023-00220) that the challenged claims of both US 8,854,595 and US 9,173,322 were unpatentable as obvious over prior art (Korean references "Kim" and "Na"). Samsung withdrew from the appeal; the USPTO Director intervened to defend the Board. The court rejected MRI's arguments on: (1) whether the prior art disclosed a "constricted convection plate," (2) the Board's construction of "access apertures" (dependent claim 8 of the '595; MRI's narrow construction was rejected), and (3) MRI's objective-indicia (commercial success/copying) evidence, which lacked a proven nexus to the claimed invention. This decision means the patent's challenged claims (the '322's claims 1–5, 7–13, and 16) stand invalidated as obvious, subject to any further review (e.g., certiorari), of which I have no information.

Related litigation (context)

• ITC Inv. No. 337-TA-1331 (MRI v. Coates Signco / Samsung): ALJ found no violation; MRI's appeal in 24-1749 (Fed. Cir.) was voluntarily dismissed Aug. 29, 2024 under Rule 42(b), each side bearing its own costs.
• District-court cases referencing this patent family include Delaware 1:17-cv-00269 and Texas Eastern 2:22-cv-00320.
• This patent is the subject of the same family as US 9,894,800 and US 10,506,738 (continuations), and US 8,854,595 (parent).

Uncertainty notes

• I could not directly query the USPTO Patent Center in this session; the bibliographic data above is sourced from Google Patents (full-text record), Unified Patents, and secondary patent databases, which are consistent with each other. Small discrepancies in day-level dates exist among sources (e.g., Unified Patents lists grant date as 2015-10-26 vs. Google's 2015-10-27; the official publication date is October 27, 2015).
• The CAFC opinion is nonprecedential and I have not reviewed the full PDF; the summary relies on the CAFC website docket entry, CourtListener, and contemporaneous case summaries (April 2026).
• I found no CAFC docket activity specific to this patent that is pending as of April 2026 beyond the 24-2228/24-2229 affirmance and the earlier dismissed 24-1749 appeal.

I'll research litigation involving US Patent 9,173,322. Let me search several sources.

I have solid leads. Let me dig deeper into the specific cases and their current status.

Based on my research (prioritizing live search results from Unified Patents, CAFC, CourtListener, UniCourt, Patexia, the Federal Register, and PatSnap), here is the known litigation involving US Patent No. 9,173,322 ("Constricted Convection Cooling System for an Electronic Display," owned by Manufacturing Resources International, Inc. ["MRI"]).

1. MRI v. Civiq Smartscapes, LLC et al. — D. Del.

• Plaintiff: Manufacturing Resources International, Inc.
• Defendants: Civiq Smartscapes, LLC; Civiq Holdings, LLC; Comark, LLC; Comark Holdings, LLC
• Jurisdiction: [U.S. District Court for the District of Delaware (Judge Richard G. Andrews)](/courts/district-of-delaware-judge)
• Case No.: 1:17-cv-00269-RGA
• Filing date: March 14, 2017
• Patents: The '322 patent was one of many MRI cooling patents asserted (claim construction covered the '322 patent along with the '595, '572, '287, '325, '633, '108, and '917 patents; the case involved up to 18 MRI patents, including 9,173,322).
• Status/Outcome: Settled — dismissed with prejudice. A joint stipulation of dismissal with prejudice was so ordered on January 24, 2020 (D.I. 364/365), terminating the case. Patexia lists status "Dismissed – Settled."

2. MRI v. [[[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) et al.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.%20et%20al.) — E.D. Tex.

• Plaintiff: Manufacturing Resources International, Inc.
• Defendants: Samsung Electronics Co., Ltd.; Samsung Electronics America, Inc.; Samsung SDS Co., Ltd.; Samsung SDS America, Inc.
• Jurisdiction: U.S. District Court for the Eastern District of Texas (Tyler Division)
• Case No.: 2:22-cv-00320
• Filing date: August 19, 2022 (complaint; jury demand same day)
• Patents: 8,854,595; 9,173,322; 9,629,287; 10,506,740; 11,013,142 (claim charts for the '322 patent were filed with the complaint as Exhibits D–F)
• Status/Outcome: Open/ongoing as of the last available docket update (UniCourt lists status "Open"). I found no final judgment in my search. Note that this case was filed the same day as the ITC complaint, and the '322 patent has since been held unpatentable in IPR (see below), which would bear on this case's viability.

3. ITC Investigation No. 337-TA-1331 — Certain Outdoor and Semi-Outdoor Electronic Displays

• Complainant: Manufacturing Resources International, Inc.
• Respondent(s): Public sources differ. PatSnap's ITC case analysis identifies the respondent as Coates Signco Pty Limited (Australian signage company; Goodwin Procter LLP as counsel), while PatSnap's Federal Circuit summary describes the underlying ITC dispute as involving Samsung outdoor display products — suggesting the investigation may have named multiple respondents, or the two sources are describing related matters. The Federal Register notice of investigation (Sept. 23, 2022, Docket 2022-20607) confirms the '322 patent was asserted (claims 4, 5, 8, 9, 12, 13, and 16) along with the '595, '287, '740, and '142 patents.
• Jurisdiction: U.S. International Trade Commission (ALJ Monica Bhattacharyya)
• Case No.: 337-TA-1331
• Filing date: Complaint filed August 19, 2022; investigation instituted September 19, 2022.
• Status/Outcome: No violation found. ALJ issued an Initial Determination of no violation on November 13, 2023; the Commission declined to review on February 28, 2024, terminating the investigation without any exclusion order. MRI appealed (see Case 5 below).

4. Samsung Electronics Co., Ltd. et al. v. MRI — PTAB IPR

• Petitioner: Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. (Goodwin Procter LLP)
• Patent Owner: Manufacturing Resources International, Inc. (Kilpatrick Townsend & Stockton LLP)
• Jurisdiction: Patent Trial and Appeal Board
• Case No.: IPR2023-00220 (Patent 9,173,322 B2)
• Filing date: Petition filed December 5, 2022; institution decision June 20, 2023.
• Claims challenged: 1–5, 7–13, and 16.
• Status/Outcome: Final Written Decision (June 18, 2024) holding all challenged claims unpatentable as obvious (primarily over the Kim and Na prior-art references). The Board credited Samsung's expert testimony that both references disclose the claimed "constricted convection plate" and gave MRI's secondary-considerations evidence little weight. This decision was appealed to the Federal Circuit (see Case 6).

5. MRI v. ITC — Federal Circuit Appeal No. 24-1749

• Appellant: Manufacturing Resources International, Inc.
• Appellee: U.S. International Trade Commission (underlying investigation 337-TA-1331; Samsung displays per PatSnap's summary)
• Jurisdiction: U.S. Court of Appeals for the Federal Circuit
• Case No.: 24-1749
• Filing date: Appeal docketed around April 2024 (appeal of the ITC no-violation determination).
• Status/Outcome: Voluntarily dismissed on August 29, 2024, under Fed. R. App. P. 42(b) pursuant to a joint agreement, with each side bearing its own costs. No merits decision; no damages or injunctive relief awarded.

6. MRI v. Squires (Director, USPTO) — Federal Circuit Appeals Nos. 24-2228 & 24-2229

• Appellant: Manufacturing Resources International, Inc.
• Appellee/Intervenor: John A. Squires, Under Secretary of Commerce for Intellectual Property and Director of the USPTO (intervening to defend the Board's IPR decisions; Samsung declined to participate after initially being named)
• Jurisdiction: U.S. Court of Appeals for the Federal Circuit
• Case Nos.: 24-2228 and 24-2229 (consolidated; these are MRI's appeals of the two IPR Final Written Decisions — the '322 patent IPR was IPR2023-00220, appealed as 24-2229, and the companion '595 patent IPR appeal as 24-2228)
• Filing date: Appeals filed in 2024 following the June 2024 IPR decisions.
• Status/Outcome: Affirmed in a nonprecedential opinion issued March 31, 2026. The Federal Circuit rejected MRI's challenges to the Board's constructions and obviousness findings (including the "constricted convection plate" and "access apertures" issues), upholding the Board's determinations that all challenged claims of the '322 patent (and the '595 patent) are unpatentable.

Notes / cautions

• I excluded the Fiber, LLC v. Ciena/Viavi/Lumentum cases (D. Colo. 13-cv-00840, 15-cv-01743, 15-cv-02135) — those concern U.S. Patent Nos. 6,430,332 and 7,095,917, not 9,173,322, despite the coincidental "332"/"917" numbers.
• The ITC respondent identification (Coates Signco vs. Samsung) is the one area where sources conflict; the Federal Register confirms the '322 patent was asserted in 337-TA-1331, and I've flagged the discrepancy above rather than resolving it definitively.
• I found no separate district-court case against Coates Signco on the '322 patent, and no other district-court or PTAB matters for this patent number beyond those listed.

Bottom line: US 9,173,322 has been litigated in at least six proceedings — the settled Delaware case (2017–2020), the open E.D. Tex. Samsung case (2022–present), the ITC investigation (no violation, 2022–2024), a PTAB IPR (all claims invalidated, 2022–2024), and two Federal Circuit appeals (one dismissed in 2024, one affirmed in March 2026). The patent's asserted claims have been held unpatentable in IPR, and that determination was affirmed by the Federal Circuit on March 31, 2026.

I'll research the PTAB record on US 9,173,322, starting with the proceeding identified in the cross-referenced sections and checking for any others.

Now let me check whether any other AIA trials targeted this specific patent, and confirm the appeal details.

AIA Trial Proceedings — US Patent 9,173,322

⚠️ Data conflict flagged up front. The structured "PTAB proceedings on file" block in this prompt states that the USPTO Open Data Portal (ODP) API returned no AIA trial proceedings for this patent as of its last ingest. That is flatly contradicted by (a) the previously generated Patent summary and Litigation summary sections in this same analysis, and (b) the public record confirmed by live search below, which shows a fully litigated IPR that reached a Final Written Decision and a precedential-signpost Federal Circuit affirmance. The ODP block appears to be a stale/empty ingest, not an accurate "no activity" finding. I have proceeded on the documented proceeding, and I have not invented any proceeding number — IPR2023-00220 is verified in the PTAB record, the FWD text, and the CAFC opinion. Treat the structured block as unreliable here.

Proceedings overview

There is exactly one AIA trial proceeding on US 9,173,322: IPR2023-00220 (Samsung v. MRI), which went to a Final Written Decision on 2024-06-18 holding all challenged claims (1–5, 7–13, 16) unpatentable as obvious, and that decision was affirmed by the Federal Circuit on 2026-03-31 — so the breakdown is one proceeding: claims invalidated (1), active (0), claims sustained (0), settled (0), institution denied (0). The defensive posture is therefore the strongest possible short of reexamination: every independent claim (1, 4, and 9) has been canceled, and the only claims never challenged (6, 14, 15) are dependent claims that hang off those canceled independents — meaning a demand letter citing this patent today is asking you to pay for claims the Board and the Federal Circuit have already held invalid.

IPR2023-00220 — [Samsung Electronics Co., Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) & Samsung Electronics America, Inc. v. Manufacturing Resources International, Inc.

• Type: Inter Partes Review (35 U.S.C. §§ 311–319)

• Filed: 2022-12-05 (petition accorded filing date 2022-12-05; Notice of Filing Date Accorded mailed 2022-12-22). A Corrected Petition was later filed (Paper 9).

• Status: Final Written Decision — all challenged claims unpatentable; affirmed on appeal. (Note: the structured ODP block's "no proceedings on file" is contradicted by the record; see flag above.)

• Judge panel: Administrative Patent Judges Jameson Lee, Jo-Anne M. Kokoski, and John A. Hudalla — Panel opinion authored by APJ Kokoski.

• Petition grounds (all § 103 obviousness; no § 102 or § 112 challenges). Eight grounds were asserted, covering every challenged claim:

  Ground	Claims	Basis
  1	4, 7	Kim (US 7,800,706) + Hong
  2	5	Kim + Hong + Tachikawa
  3	8	Kim + Hong + Takahashi
  4	1, 2, 3	Kim + Tachikawa
  5	4, 8, 9, 10, 16	Na (KR 10-2006-0016469)
  6	7, 12, 13	Na + Kim
  7	11	Na + Tachikawa
  8	9, 12, 13	Kimura (US 2006/0199514)

  The keystone dispute across every independent claim was whether Kim's "shield cover" and/or Na's "bottom plate" disclose the claimed "constricted convection plate," plus claim-construction questions on "substantially parallel," the "fan … to draw … air" limitation, the "means for forcing air" limitation, and (via dependent claim 8) "access apertures."

• Institution decision: Instituted on 2023-06-20 on all challenged claims and all grounds presented (Paper 11). The Board found a reasonable likelihood of prevailing and did not exercise § 325(d) or § 314(a) discretionary denial. (A consolidated Scheduling Order issued the same day; oral hearing later consolidated with IPR2023-00199 on the '595 patent.)

• Final Written Decision: 2024-06-18 — caption reads "Determining All Challenged Claims Unpatentable — 35 U.S.C. § 318(a); Dismissing Petitioner's Motion to Strike." The Board held, by a preponderance of the evidence, that claims 1–5, 7–13, and 16 of the '322 patent are unpatentable. Claim-level result:

  • Independent claim 1 — CANCELED (obvious over Kim + Tachikawa).
  • Independent claim 4 — CANCELED (obvious over Kim + Hong; also over Na).
  • Independent claim 9 — CANCELED (obvious over Na; also over Kimura).
  • Every challenged dependent claim (2, 3, 5, 7, 8, 10, 11, 12, 13, 16) — CANCELED.
  • No challenged claim survived. The Board credited Samsung's expert (Robert Smith-Gillespie) that the narrow space enclosed by Kim's shield cover is "constricted," and that Na's no-through-holes bottom-plate embodiment teaches the claimed constricted convection plate. It also rejected MRI's proposed narrowing of "access apertures" and, on the objective-indicia record, assigned MRI's commercial-success and copying evidence little or no weight, finding no nexus and finding that Samsung had designed its accused cooling system before the alleged tear-down.

• Claims NOT challenged: 6, 14, and 15 were never challenged. Claim 6 depends from (canceled) claim 4; claims 14 and 15 depend from (canceled) claim 9. They were therefore not adjudicated — but they are practically worthless because a dependent claim cannot be infringed without practicing the canceled independent claim from which it depends.

• Settlement / termination: None. The parties litigated to a Final Written Decision; there was no adverse-judgment termination and no motion-to-amend (no substitute claims were entered). Petitioner's Motion to Strike PO Exhibits 2055–2056 was dismissed as moot.

• Appeal: Yes. MRI appealed to the Federal Circuit as No. 24-2229, consolidated with the companion '595 appeal No. 24-2228. Samsung withdrew from the appeal; the USPTO Director intervened as of right to defend the Board. In a nonprecedential opinion issued 2026-03-31 (Manufacturing Resources Int'l, Inc. v. Squires, No. 24-2228; Judge Taranto), the court AFFIRMED the Board. The court held that (i) substantial evidence supported the findings that both Kim and Na disclose the claimed constricted convection plate; (ii) the Board did not err in its construction of "access apertures" (rejecting MRI's hardware-access/plugging narrowing, since the spec makes plugging optional); and (iii) the Board properly discounted MRI's objective indicia for lack of nexus. Opinion: https://cafc.uscourts.gov/opinions-orders/24-2228.OPINION.3-31-2026_2668801.pdf — also on CourtListener: https://www.courtlistener.com/opinion/[10830337](/patent/10830337)/manufacturing-resources-international-inc-v-squires/

• Defensive value: Claim 1 is dead, claim 4 is dead, claim 9 is dead — and the Federal Circuit has now affirmed that on the merits. Any infringement theory built on claims 1–5, 7–13, or 16 is sanction-bait; a demand letter citing them should be met with the FWD and the 24-2228 opinion. The only escape hatch for MRI would be claims 6, 14, 15, which are dependent on canceled independents and therefore cannot be practiced without a canceled claim.

Strategic summary

Claim status map. Of the 16 claims of the '322 patent:

• CANCELED / INVALIDATED (13): claims 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 16. This includes all three independents (1, 4, 9) and every challenged dependent. The invalidation is now affirmed by the Federal Circuit (2026-03-31), subject only to further review (e.g., a petition for certiorari, of which I have no information).
• NOT CHALLENGED (3): claims 6, 14, 15. Never adjudicated in IPR, but all three are dependent claims arising from canceled independents (claim 6 ← claim 4; claims 14, 15 ← claim 9). Legally they were not canceled, but they cannot independently support infringement of the claimed system because they incorporate the canceled base limitations. Practically, the patent is fully neutralized for assertion purposes.
• No claim has been sustained. There is no surviving independent claim and no amendment/substitute claim was ever entered (MRI filed no § 316(d) motion to amend).

Estoppel landscape (§ 315(e)(2)). Samsung — and its named real parties-in-interest (Samsung Electronics Co., Ltd.; Samsung Electronics America, Inc.; Samsung SDS Co., Ltd.; Samsung SDS America, Inc.; Coates Signco Pty Limited; Coates US Inc.; and Industrial Enclosure Corporation d/b/a Palmer Digital Group) — are estopped from asserting before the district court any ground raised in the IPR or that they reasonably could have raised. For a new defendant not in privity with Samsung/Coates, § 315(e)(2) estoppel does not attach, so the full prior-art field (Kim, Na, Hong, Tachikawa, Takahashi, Kimura, and art beyond the petition) remains available as an invalidity defense. But given that the claims are already canceled by a final, court-affirmed judgment, a new defendant's cheapest and strongest position is the affirmance itself, not a fresh IPR.

Pattern signals. (1) Same petitioner, coordinated campaign: Samsung filed a five-IPR cluster against the MRI display-cooling family, all on 2022-12-05 or thereabouts, all with the same three-APJ panel (Lee, Kokoski, Hudalla), and all consolidated for a single oral hearing cycle — IPR2023-00199 ('595, all challenged claims unpatentable), IPR2023-00220 (this '322 patent), IPR2023-00221 ('142), IPR2023-00254 ('740), and IPR2023-00255 ('287). Critically, only IPR2023-00220 targets the '322 patent — the other four challenge sibling patents, not this one. (2) No defensive aggregator in this chain: the petitioner of record is Samsung (Goodwin Procter), not a third-party funder like Unified Patents. (3) Patent owner fought hard and lost: MRI (Kilpatrick Townsend & Stockton; John C. Alemanni) relied on objective indicia (commercial success, copying) and appealed both FWDs — the appeal was consolidated and affirmed against it after the Director intervened. Samsung's withdrawal left the USPTO defending the Board, and the Board's findings held up under substantial-evidence review. (4) Related record: the ITC's 2024-02-28 Commission notice declining to review the ALJ's no-violation determination in Inv. No. 337-TA-1331 was submitted as supplemental authority in all five IPRs (Ex. 3007), and MRI's ITC appeal (Fed. Cir. 24-1749) was voluntarily dismissed on 2024-08-29 — the whole enforcement push collapsed in parallel across forums.

Recommended next steps

1. If you are a defendant facing assertion of the '322 patent: quote the FWD disposition verbatim — the Board "determine[d] that claims 1–5, 7–13, and 16 … are unpatentable" — and the Federal Circuit's affirmance of 2026-03-31 in MRI v. Squires, No. 24-2228. Link the primary sources:

   • FWD / docket (PTAB E2E): https://ptab.uspto.gov/ (search IPR2023-00220); mirrored at Docket Alarm: https://www.docketalarm.com/cases/PTAB/IPR2023-00220/Samsung_Electronics_Co._Ltd._v._Manufacturing_Resources_International_Inc/
   • CAFC opinion (24-2228): https://cafc.uscourts.gov/opinions-orders/24-2228.OPINION.3-31-2026_2668801.pdf
   • CourtListener: https://www.courtlistener.com/opinion/10830337/manufacturing-resources-international-inc-v-squires/
     If MRI asserts claims 1, 4, or 9 (or any challenged dependent), the claims are canceled and the assertion is baseless. If MRI asserts claims 6, 14, or 15, point out that each depends from a canceled independent claim and cannot be infringed in isolation — demand the infringement theory in writing.

2. No active proceedings to monitor. There is no pending AIA trial on the '322 patent: IPR2023-00220 is final and affirmed. Because the one-year FWD deadline was met on 2024-06-18 (inside the statutory window from the 2023-06-20 institution), no PTAB milestone remains open. The only residual PTAB risk would be a belated follow-on petition by a different (non-estopped) party — but any such petition would face § 325(d) and § 314(a) headwinds against art the Board has already considered, and the Director's 2026-03-11 discretionary-factor memorandum tying institution to U.S. manufacturing/small-business status (per Patently-O), which cuts in the patent owner's favor here. Watch for that only if a new, unrelated defendant appears.

3. Watch the appellate endpoint. Because the affirmance is nonprecedential, the invalidity of these claims binds the parties but does not itself set circuit-wide law. For a defendant, the operative protection is the specific final judgment of unpatentability in IPR2023-00220, affirmed in 24-2228/24-2229 — cite it as issue-preclusive against MRI as to these claims.

4. Do not rely on the ODP "no proceedings" signal. If a docketing or diligence system pulls PTAB data for this patent and shows nothing, that system is missing IPR2023-00220 — confirm against PTAB E2E / Docket Alarm before relying on it, and reconcile it with the previously generated sections of this analysis, which correctly identified the IPR and the Federal Circuit affirmance.

Uncertainty notes: (a) I did not directly query PTAB E2E in this session; the proceeding details, panel, grounds, institution date, and FWD text are drawn from the FWD document itself, Docket Alarm filings, Patexia, and the CAFC opinion, which are mutually consistent. (b) The FWD entered date is 2024-06-18 (Patexia "Decision Date"), and a joint proposed-redactions filing is dated 2024-07-03, which the Google Patents citation list labels as the FWD date — I treat 2024-06-18 as the entry date and 2024-07-03 as the public/redacted version, and the CAFC confirms "June 2024." (c) Full ground-by-ground claim mapping for Ground 8 (Kimura) is inferred from the Petition's table of contents and Petitioner's Reply headings; I have not independently verified the FWD's internal citation page numbers. (d) I found no second IPR, PGR, or CBM on the '322 patent — the four other Samsung IPRs (00199, 00221, 00254, 00255) target different patents and are referenced only as "related."

I'll research the assignment record for US 9,173,322 before drafting.

Let me try to pin down reel/frame numbers and correspondent details for these recordings.

I was unable to complete the final two verification searches before hitting the tool-call limit, so I'll flag the two gaps explicitly rather than fill them speculatively. Everything below is grounded in the assignment/legal-events records set out in the authoritative patent text provided, plus the sources I did retrieve.

Important sourcing caveat up front: the Google Patents legal-events block reproduced in this patent's own record lists the conveyance events (dates, types, assignor/assignee) but does not expose reel/frame numbers or the correspondent of record. I could not retrieve those from live sources in this session. I therefore record the dates and conveyance types as authoritative, and mark reel/frame and correspondent as not retrieved — I will not invent them.

Inventors

Pattern notes:

• Solo inventorship across an entire display-cooling portfolio is unusual; MRI's US 8,854,595 (the parent of this case) lists Dunn as a named inventor per the Civiq expert declaration I retrieved, and MRI's subsequent continuations (US 9,894,800, US 10,506,738) are also Dunn-led. This is a centrally-attributed corporate portfolio, not a distributed inventor group.
• No departures are visible or inferable. The inventor assignment runs to the operating company, not away from it, and Dunn continues to appear as inventor on MRI continuations filed in 2015 and 2017 (the '800 and '738 applications per the Priority Applications table). There is no evidence of the "all inventors exit within 12 months" fire-sale precursor pattern.
• I could not verify Dunn's specific job title at MRI from a primary source; I am not asserting one.

Original assignee

Manufacturing Resources International, Inc. ("MRI") — named on the face of the issued patent as original and current assignee.

• Primary line of business: MRI designs, manufactures and sells outdoor / semi-outdoor digital display assemblies (digital signage, drive-through and quick-service-restaurant displays, high-brightness LCD enclosures). It is the manufacturing entity behind the "constricted convection" architecture this patent claims.
• Did they ship a product embodying the claims? Yes, strongly indicated. The asserted products in the parallel litigations are MRI's own outdoor display assemblies (e.g., the ITC investigation was styled Certain Outdoor and Semi-Outdoor Electronic Displays), and the Civiq/Comark suit was over competing outdoor signage products. MRI is a seller of the claimed subject matter, not a licensor.
• Current status: Operating, privately held. No SEC registration (no 10-K/8-K trail), so no public financials. Headquarters in the Alpharetta, Georgia area (MRI's corporate address); the assignment/litigation correspondent address on the family is Standley Law Group, 6300 Riverside Drive, Dublin, OH 43017.
• Not acquired, not dissolved, and I found no bankruptcy record.

Assignment timeline

Chronological, from the legal-events record on this patent/application (US 14/508,621). Reel/frame and correspondent of record are not available in the source I was able to access — neither should be treated as "absent from the record"; they simply were not retrieved.

• 2014-12-04 (executed) / recorded 2014-12-04 — Reel nnnnnn/nnnn (not retrieved)

  • Conveyance: Security Interest ("SECURITY INTEREST (SEE DOCUMENT FOR DETAILS)")
  • Assignor: Manufacturing Resources International, Inc.
  • Assignee: Bank of America, N.A. (as administrative agent)
  • Correspondent: not retrieved. (Note: Standley Law Group LLP, Dublin, OH — MRI's prosecution and litigation counsel of record on this family — is the most likely filer, but I have not verified this on the assignment cover sheet.)
  • Context: Securitization — MRI pledges its patent portfolio (including this then-pending application, filed only ~2 months earlier) as collateral under a credit facility.

• 2015-07-06 (executed) / recorded 2015-07-06 — Reel nnnnnn/nnnn (not retrieved)

  • Conveyance: Assignment of Assignor's Interest ("ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)")
  • Assignor: Dunn, William (inventor)
  • Assignee: Manufacturing Resources International, Inc.
  • Correspondent: not retrieved.
  • Context: Inventor-to-employer assignment. Recorded against the newly-filed continuation (14/508,621) roughly four months before grant — best characterized as a confirmatory/recordation assignment, not a portfolio sale.

• 2015-07-09 (executed) / recorded 2015-07-09 — Reel nnnnnn/nnnn (not retrieved)

  • Conveyance: Security Interest ("SECURITY INTEREST (SEE DOCUMENT FOR DETAILS)")
  • Assignor: Manufacturing Resources International, Inc.
  • Assignee: Fifth Third Bank
  • Correspondent: not retrieved.
  • Context: Securitization / refinancing — a second lender takes a security interest three days after the inventor assignment, consistent with replacement or layered debt financing.

• 2018-06-15 (executed) / recorded 2018-06-15 — Reel nnnnnn/nnnn (not retrieved)

  • Conveyance: Release by Secured Party
  • Assignor: Bank of America, N.A., as administrative agent
  • Assignee: Manufacturing Resources International, Inc.
  • Correspondent: not retrieved.
  • Context: Lien release / payoff — Bank of America's collateral interest is extinguished; nothing transfers to a third party.

• 2018-08-24 (executed) / recorded 2018-08-24 — Reel nnnnnn/nnnn (not retrieved)

  • Conveyance: Release by Secured Party
  • Assignor: Fifth Third Bank
  • Assignee: Manufacturing Resources International, Inc.
  • Correspondent: not retrieved.
  • Context: Lien release / payoff — Fifth Third's collateral interest is extinguished; MRI ends the decade holding unencumbered title.

No assignment records exist that move the patent out of MRI. The chain is: MRI (owner) ⇄ two lenders (security interests in, then out); inventor → MRI. Nothing after 2018-08-24.

Correspondent recurrence flag: I could not obtain assignment correspondents, so I can only report the counsel pattern, not the recording pattern. Standley Law Group LLP (Jeffrey S. Standley; F. Michael Speed, Jr.; James Lee Kwak) appears as MRI's counsel of record across this family and as litigation counsel in MRI v. Civiq Smartscapes, D. Del. 1:17-cv-00269 (court filing retrieved). That is recurring counsel for an operating company, not a repeat NPE filing agent — and, per your instruction, a single/related-firm appearance is not itself a finding.

NPE / troll-pattern signals

1. Shell-entity transfer — Not present. The chain contains no LLC with an "IP / Patents / Licensing / Holdings / Ventures" suffix. Every equity conveyance runs to MRI, the operating manufacturer. The only non-MRI parties in the record are Bank of America, N.A. and Fifth Third Bank, both acting as secured lenders, not owners.

2. Known asserter in the chain — Not present. MRI appears in none of the listed NPE rosters (Acacia, Marathon, IV, IPNav, Wi-LAN/Conversant, Vringo, Pendrell, Round Rock, etc.). MRI is a high-frequency plaintiff — Civiq/Comark (D. Del. 1:17-cv-00269, settled Jan. 2020), Samsung (E.D. Tex. 2:22-cv-00320), and ITC 337-TA-1331 — but it sues in its own name as a competitor, and Unified Patents' own parent-company field for this patent reads "Manufacturing Resources International Inc."

3. Repeat correspondent across the chain — Unclear (data gap). I could not retrieve the correspondent of record on any of the five recordings, so recurrence cannot be tested. What is documented is that one firm (Standley Law Group LLP, Dublin, OH) is MRI's counsel across prosecution and enforcement of this family. That is a single-client operating company pattern; there is no evidence of a lawyer running unrelated shell LLCs through this chain.

4. Cascading transfers — Not present. Only five recorded events over ~4 years, and three are security-interest/release pairs that cancel out. No chained LLCs, no shared correspondent addresses among adverse parties, no common-principal stacking.

5. Pre-litigation transfer — Not present. The last recorded conveyance is the 2018-08-24 release; the first suit naming this patent (MRI v. Civiq, D. Del.) was filed 2017-03-14. The 2018 recordings therefore follow the first litigation, and the only pre-suit event in the window is the 2015 security interest — a financing, not an assertion-enabling transfer.

6. Bankruptcy fire-sale — Not present / no evidence. No Chapter 7 or 11 record for MRI surfaced; both 2018 recordings are lien releases in MRI's favor, the opposite of a distressed sale.

7. Privateering — Not present. MRI did not hand the patent to a proxy. It asserts the '322 patent itself, alongside four sibling patents (US 8,854,595; 9,629,287; 10,506,740; 11,013,142), against direct competitors.

8. Defensive aggregator (anti-NPE) — Not present. The chain terminates at MRI, an operating manufacturer, not at RPX, AST, LOT, Unified Patents, or OIN. The patent has not been neutralized by acquisition into a defensive pool (though see the invalidity note below — it has been neutralized by adjudication, which is a different mechanism).

Cross-reference / consistency flag: my earlier sections state the patent is "Active" with an anticipated expiration around 2028-09-19 (Google) and that the Federal Circuit affirmed PTAB holdings of unpatentability on March 31, 2026. These are not in conflict — ownership and validity are separate, and the assignment record shows MRI still holds title. But the two should be read together: MRI owns a patent whose challenged claims (1–5, 7–13, 16) have been held unpatentable. I also note a minor source discrepancy, not a contradiction: Unified Patents lists priority 2008-03-02 and grant 2015-10-26, while Google Patents lists 2008-03-03 and 2015-10-27; the family's earliest provisional is US 61/033,064 (filed 2008-03-03), so Google's dates are the better-supported ones.

Verdict

Operating-company assertion.

Justification: the entire recorded chain begins and ends with Manufacturing Resources International, Inc. — the inventor assignment (Dunn → MRI, executed/recorded 2015-07-06) and the two lien releases (2018-06-15 Bank of America; 2018-08-24 Fifth Third Bank) all terminate in MRI, with the sole non-MRI parties being secured lenders whose interests were extinguished. MRI is a private operating manufacturer of outdoor digital displays and has asserted this patent in its own name against direct competitors (Civiq/Comark in D. Del. 1:17-cv-00269; Samsung in E.D. Tex. 2:22-cv-00320; ITC 337-TA-1331). Zero of the eight NPE signals are present on the available record.

Verification: search the patent number at the USPTO Assignment Center — https://assignmentcenter.uspto.gov/ (legacy interface: https://assignment.uspto.gov/patent/index.html). Expect five records for application 14/508,621; retrieve the reel/frame and correspondent fields from that search to close the two gaps flagged above.

Explicit uncertainty statement: I could not query the Assignment Center directly in this session, and the patent text I was given reproduces the legal events without reel/frame numbers or correspondents. I have not fabricated those fields. If the Assignment Center shows a sixth, later recording that transfers title away from MRI, that would change the verdict — but nothing in any source I retrieved supports one.

I'll research the specific prior-art citations for US 9,173,322. Let me run several targeted searches.

Let me dig into the IPR ground art and several more-cited references.

Prior Art Analysis — US Patent No. 9,173,322 B2

"Constricted Convection Cooling System for an Electronic Display" • Inventor: William Dunn • Assignee: Manufacturing Resources International, Inc. • App. No. 14/508,621 • Filed Oct. 7, 2014 • Granted Oct. 27, 2015 • Earliest priority Mar. 3, 2008

0. Scope, sources, and two important flags

Sources used: (1) the authoritative full text of the patent as provided (Google Patents, patents.google.com/patent/US9173322B2/en), which carries the "Citations (44)" and "Families citing this family (49)" tables; (2) live searches of Google Patents, PTAB docket records (Docket Alarm), the CAFC opinion PDF for No. 24-2228, and secondary patent databases. I could not directly query USPTO Patent Center in this session, so filing/publication dates are taken from the patent's own front-page citation table and are labeled as such.

Flag 1 — date discrepancy (contradiction to report). The task heading says "Current Date: April 26, 2026," while the system instruction in this session says today is 2026-09-14. The previously generated summary for this patent describes a CAFC affirmance dated March 31, 2026. The March 31, 2026 CAFC decision is consistent with both date statements; the April-26-vs-September-14 discrepancy is unresolved and does not affect the prior-art analysis below.

Flag 2 — two different bodies of prior art must not be conflated. A patent has:

• (A) References cited in (of record in) the patent — the "Citations (44)" list. These are the examiner/cited-art references and are the correct answer to "each patent citation for 9173322."
• (B) References that cite the patent — the "Cited By (36)" and "Families Citing this family (49)" tables. These post-date the '322 patent and are not §102 prior art against it. They are excluded.

Separately, there is a (C) third universe — the references actually adjudicated in IPR2023-00220 (Kim, Na, Kimura, Cho, Tachikawa, Takahashi, Hong, Kochiyama, Burke). Two of those (Cho, and the Funai publication) also appear on the face of the '322 patent; the rest do not. Because the task asks about "prior art for US patent 9173322," I treat the IPR ground art as the most legally consequential prior art and cover it in §3.

Critical framing caveat on §102 vs. §103. The task asks which claims each reference "potentially anticipates under 35 U.S.C. § 102." Anticipation requires a single reference disclosing every element arranged as claimed. Very few of the 44 references of record do that for the independent claims (1, 4, 9). Most are §103 obviousness references (single-reference obviousness or in combination). I state per-reference which is which rather than overclaiming anticipation. The claims at issue are:

1. The 44 references of record (patent citations) — complete table

Columns: citation; priority date (per Google Patents front page); publication date; assignee; brief description; and the claim(s) it could bear on, with an honest tag of whether it is §102-anticipatory alone or §103-relevant. "§102-eligible" simply means it qualifies as prior art (pre-2008 priority or §102(e) US filing before Mar. 3, 2008).

Reading of the table. The 44 references of record fall into five clusters:

1. Display heating / temperature-control background (pre-2000): #1–#9, #11–#12, #15–#17. Not anticipatory; §103 filler at best.
2. Environmentally-sealed / outdoor display enclosure cooling: #10, #14, #18, #23, #29, #31, #32. Most germane to claims 1, 9, 12.
3. LCD cooling apparatus (Samsung/LG/Korean): #36, #39, #40, #44. Germane to claims 1, 4, 7, 9, 12, 13, 16.
4. LED backlight construction/cooling: #34, #35, #41. Germane to claims 4, 16.
5. Fan mounting / generic electronics cooling: #42, #43. Germane to claims 1, 13 and the means-for-forcing-air of claim 9.
6. Remainder (#2, #19–#22, #24, #26–#28, #30, #33, #37, #38): optics, cells, sensors — background only.

2. The five references of record that most closely map to the independent claims

These are the references I would rank as the "most relevant prior art" on the face of US 9,173,322:

(a) US 2006/0132699 A1 — Cho et al. (Samsung), pub. 2006-06-22 (= IPR Exhibit 1008)
A cooling apparatus with a casing having first and second openings forming an air path, a heat sink, and a cooling fan, mounted at an external surface of the display chassis at a position corresponding to the backlight. Directly parallels claim 1 (fan + air path between components), claim 4 (cooling the backlight region), claim 7/12 (openings in a housing permitting air flow), and claim 13 (fan near an opening). Primary §102/§103 reference.

(b) US 7,284,874 B2 — LG.Philips LCD, pub. 2007-10-23
LED backlight with a PCB carrying LEDs, a heat pipe under the PCB, and a heat sink; heat from LEDs conducted through the PCB rearward. Directly maps to claim 4's "PCB having front and back sides, LEDs mounted on the front side, a posterior surface on the rear side of the PCB" and claim 16's "LED backlight LCD where the posterior surface is the rear surface of the backlight assembly." It does not show the claimed fan-drawn constricted convection plate substantially parallel to that surface (it uses conduction + heat pipe), so a full §102 anticipation of claim 4 is doubtful — but it is a powerful §103 reference. Primary reference for claims 4/16.

(c) US 5,748,269 A — Westinghouse Air Brake, pub. 1998-05-05
"Environmentally-sealed, convectively-cooled active-matrix LCD." The clearest single-reference disclosure of a sealed enclosure with convective cooling behind the display among the 44. Best §102 candidate among the of-record art for the enclosure aspects of claim 1/9, though the "constricted convection plate" and bracket limitations still need mapping.

(d) US 2008/0218446 A1 — Funai Electric, pub. 2008-09-11 (= IPR Exhibit 1036)
Chassis bracket at the rear of the display, a fan holder, fans mounted between the panel and the rear cabinet with suction/discharge slits. Maps to claim 1's "at least one bracket which connects the posterior display surface with the constricted convection plate" and claim 13's "plurality of fans." Used by Samsung in the IPR precisely for the bracket/fan limitations.

(e) US 5,991,153 A — Lacerta Enterprises, pub. 1999-11-23
"Heat transfer system and method for electronic displays" — moving air relative to a display enclosure to remove heat. §103 core reference for claims 1/9/12; supports the general "air moved between a panel and a rear structure" concept.

Honest bottom line on §102: No single one of the 44 references of record appears to disclose all elements of claims 1, 4, or 9 as arranged. The of-record art is best characterized as §103 art. That is consistent with the outcome of the actual adversarial proceeding (below), where the patent was invalidated on obviousness, not anticipation.

3. The prior art actually adjudicated — IPR2023-00220 (the controlling prior-art set)

Because the previously generated sections already cover the IPR outcome, I add here only what belongs to this task: which references were the prior art, and what they disclose.

The PTAB record (Samsung Electronics Co. v. MRI, IPR2023-00220, FWD June 18, 2024; affirmed Fed. Cir. Nos. 24-2228/24-2229, Mar. 31, 2026) applied:

Claim coverage in the petition/FWD: challenged claims 1–5, 7–13, and 16 — i.e., the entire asserted set. Grounds were structured as: Kim (+Hong/Tachikawa/Takahashi) for claims 1–5, 7, 8; Na (+Kim/Tachikawa) for claims 4, 7–13, 16; Kimura grounds for claims 1–3, 9, 11–13, 16. This means the prior art was held to map to every challenged independent and dependent claim:

• Claim 1 — Kim/Na/Kimura (plate behind display; fan-driven air).
• Claim 4 — Kim+Na (Na: backlight plate and LED-generated heat; Na+Kim: PCB/backlight) and Kimura.
• Claim 9 — Na, Kimura (plate covering majority; means for forcing air).
• Claims 3, 5 — parallel plate (Kim); bracket (Tachikawa).
• Claims 6, 14, 15 — these claims were not among the challenged/instituted set in IPR2023-00220 (the challenge covered 1–5, 7–13, 16). So claim 6 (thermoelectric unit) and claims 14–15 (closed-loop front-surface gas) were not adjudicated in that IPR. That matters: the of-record art on those points is the heating/closed-loop group (#1–#9, #25), which is weaker.

4. Consolidated claim-by-claim prior-art map

5. Caveats and open items

1. Anticipation is a high bar, and I am not asserting it lightly. For the vast majority of the 44 cited references, the correct characterization is §103 obviousness art, not §102 anticipation. I have tagged the few genuine §102 candidates (chiefly Westinghouse '269 for the enclosure/convective-cooling aspects of claims 1/9, and LG '874 for the PCB/LED aspects of claims 4/16) while flagging that even those do not disclose all elements.
2. The of-record art is not the art that killed the patent. The reference set that actually invalidated claims 1–5, 7–13, and 16 in IPR2023-00220 (Kim '706 and Na '469, with secondaries) is not on the face of the '322 patent, so a reader who only checks the "Citations (44)" table will miss the controlling prior art.
3. Claims 6 and 14–15 were not adjudicated in IPR2023-00220 and are not clearly met by any of the 44 cited references; they are the residual claims supported by the weakest prior-art record in this analysis.
4. Date reliability. The dates in §1 are Google Patents front-page priority/publication dates; for the foreign-priority publications (JP, KR, WO, GB) and pre-AIA §102(e) references, the US filing date governs §102 status, which I have not independently verified against Patent Center in this session. Treat individual date cells as approximate.
5. Compliance check on identifiers. I have kept every patent/publication number exactly as it appears in the source (e.g., "US 2008/0218446 A1," "KR 10-2006-0016469," "JP H11-68363"), and I have not substituted the similarly numbered Fiber, LLC patents (6,430,332 / 7,095,917) that the previously generated litigation section correctly excluded.

I'll ground this obviousness analysis in the prior-art references actually relied on in the record, then build the § 103 combinations. Let me verify the key references.

Let me pin down the secondary references and the Board's claim constructions.

Obviousness Analysis — US 9,173,322 B2 under 35 U.S.C. § 103

Analyst report. Builds on the previously generated Patent summary, Litigation summary, PTAB challenges, and Assignment history sections; those are treated as authoritative for the grounds table, the IPR/FWD facts, and the CAFC affirmance. This section goes deeper on the § 103 merits — element mapping, motivation to combine, and the counter-argument posture — and does not re-list the grounds table.

0. Scope, sources, and relationship to the earlier sections

The prior PTAB challenges section already established the operative fact pattern: a single AIA trial (IPR2023-00220, Samsung v. MRI), a 2024-06-18 Final Written Decision holding claims 1–5, 7–13, and 16 unpatentable as obvious, and a 2026-03-31 Federal Circuit affirmance in MRI v. Squires, No. 24-2228 (nonprecedential, Judge Taranto). The Prior Art section of the patent page supplies the reference set — both the Samsung IPR references and the examiner-cited art (§ "Citations (44)").

This section answers the substantive § 103 question: which combinations render the claims obvious, and why a POSITA would have combined them.

Rule applied: I have not seen the FWD document itself in this session; the holding (all challenged claims unpatentable) and the ground structure come from the Petition, the Patent Owner Response, the Petitioner Reply, and the earlier PTAB section — which are mutually consistent. Where the record is thin (the secondary references' content, as opposed to their use), I say so explicitly rather than fill the gap.

Governing statute. The '322's claims all trace to a 2008-03-03 earliest priority date and the application (14/508,621) is a straight continuation of a 2009 application. On that basis the claims appear to be governed by pre-AIA § 103(a) rather than AIA § 103, because no claim carries an effective filing date on or after 2013-03-16. The substantive test is the same either way: the Graham v. John Deere factors (scope/content of the art; differences; level of ordinary skill; objective indicia), applied through the KSR Int'l v. Teleflex lens for combinations. I flag this as an appears-to conclusion, since the priority chain's validity is not something I can adjudicate here.

1. Level of ordinary skill in the art (POSITA)

For a 2008 effective date, a POSITA in this field would have:

• a bachelor's degree in mechanical engineering, applied physics, or a related discipline, plus roughly 2–4 years of experience in the thermal management of flat-panel electronic displays (LCD/plasma backlight cooling, enclosure airflow design, or fans-and-fins heat dissipation); or
• equivalent practical experience.

This is the classic profile the field's own patents describe: the '322 specification's BACKGROUND concedes that "conductive and convective heat transfer systems for electronic displays are known," that "systems of the past … relied primarily on fans for moving air past the components to be cooled," and that known systems "move[d] the heated air into convectively thermal communication with fins." (See the patent's own BACKGROUND and SUMMARY.) A person with that background would treat confining and accelerating airflow across a hot rear surface as a routine fluid-mechanics/thermal-design exercise — which is the crux of the case.

I note the Board did not have to resolve a disputed POSITA level to reach its result; the combinations were found obvious on the unremarkable "display thermal engineer" profile above.

2. The prior-art set — identity, dates, and § 102 status

Additional prior art of record from the "Citations (44)" list that reinforces the same combinations (all examiner-cited against the '322, all § 102(b) art):

• US 5,748,269 (Westinghouse) — "Environmentally-sealed, convectively-cooled active matrix liquid crystal display."
• US 5,991,153 (Lacerta) — "Heat transfer system and method for electronic displays."
• US 6,493,440 (Gilbarco) — "Thermal management for a thin environmentally-sealed LCD display enclosure."
• US 7,284,874 (LG.Philips LCD) — "LED backlight unit including cooling structure" (directly on point for claims 4/16's LED-on-PCB backlight).
• GB 2,402,205 A (Densitron) — "A display system cabinet and display system including heat removal means."
• WO 2005/079129 A1 (Inssimainos) — "Procedure and apparatus for controlling the temperature of a display surface."

I describe the secondary references (Tachikawa, Hong, Takahashi) at the level the party headings support; I have not read their full texts, and I flag that in § 8.

3. Independent claim 1 — element-by-element (§ 103 via Kim + Tachikawa)

Claim 1 requires: (a) a housed display with a posterior display surface; (b) a constricted convection plate placed posterior to that surface and covering the majority of it; (c) at least one bracket connecting the display surface to the plate; (d) a fan placed to draw ambient air between the plate and the rear posterior.

Motivation to combine Kim + Tachikawa. Both are in the same field (display/backlight thermal management); Kim already mounts its shield cover "supported by at least one of the backlight unit and the casing," so adding a discrete bracket as the mounting structure is the substitution of a known mechanical expedient (KSR) with a predictable result — nothing more than a design choice in how to space the plate from the rear surface, which is exactly what the '322 acknowledges is a dimensional/thermal design variable ("[t]he width of the constricted convection channel … may vary according to the thermal requirements of a particular application").

4. Independent claim 4 — element-by-element (§ 103 via Kim + Hong)

Claim 4 requires an LCD: a liquid crystal stack; a backlight assembly behind it comprising a PCB with front/back sides, LEDs mounted on the front side, and a posterior surface on the rear side of the PCB; a constricted convection plate behind and substantially parallel to that PCB surface; and a fan positioned to draw air between the plate and the posterior surface.

Motivation to combine Kim + Hong. The two references solve the same problem — removing heat from a display's LED backlight — using complementary pieces: Kim supplies the constricted rear channel + fan; Hong supplies the specific PCB/LED backlight. A POSITA seeking to cool a PCB-based LED backlight (the very configuration the '322 specification describes: "a printed circuit board (PCB) with a plurality of LEDs mounted to the anterior surface … a metal core PCB … the posterior surface of the PCB may be metallic") would plainly look to a rear-plate-and-fan arrangement. The combination is a juxtaposition of known elements with no change in their respective functions — the classic KSR "predictable result" combination. The Patent Owner's opposition (no explicit motivation) was rejected; the Board found the combination supported.

5. Independent claim 9 — element-by-element (§ 103 via Na, alternatively Kimura)

Claim 9 requires: a display with a front display surface and a posterior surface where no electronics are mounted; a constricted convection plate behind it covering a majority; and a means for forcing air between the plate and the posterior surface (§ 112(f) — the disclosed structure is fan 52 and equivalents).

Motivation to combine. Both Na and Kimura attack the same problem — heat from LED/backlight sources concentrated in a thin rear region — and both disclose moving air along the rear surface of the backlight/light source, not through the whole interior. The '322's own SUMMARY frames the invention as a departure from "systems of the past … that function to cool an entire interior of the display by one or more fans and fins." Once the POSITA adopts the goal of localized, directed rear-surface cooling (which Na and Kimura teach), placing a channel-defining plate behind the display and driving air through it is the natural and predictable implementation. Kimura's stated benefit — uniform cooling of the entire backlight — supplies the motivation to size the plate to cover the majority of the rear surface, which is precisely what the "majority" limitation requires.

6. Dependent claims — § 103 mapping

7. The consolidated motivation-to-combine case (KSR rationales)

The Board's obviousness holding rests on the ordinary KSR rationales, all of which apply cleanly here:

1. Same field of endeavor / common problem. Kim, Na, Kimura, Cho, Hong, Tachikawa, Takahashi (and the examiner-cited Lacerta, Westinghouse, Gilbarco, LG.Philips, Densitron references) all concern thermal management of flat-panel electronic displays, and several concern backlight/LED cooling specifically. Combination across a single, well-defined art is the paradigm of predictable-result obviousness.

2. Express teaching within the primary reference. Kim is not merely analogous — it discloses the very structure the claims recite: a cover plate behind the backlight, with cooling air flowing through the space between the cover and the backlight, moved by a fan that can draw ambient air from outside. The '322's claimed arrangement is thus an optimization of a known structure (sizing the plate, adding brackets, adding service apertures), not a new architecture.

3. Predictable result of a known physical principle. Constricting an airflow path raises velocity and thins the boundary layer, increasing convective heat transfer — a basic fluid-mechanics result. The specification itself concedes the channel width is set by "thermal requirements," i.e., a routine engineering parameter (≤ 0.5 in; 0.5–1 in; 1–5 in).

4. Design incentive / market forces. The '322's own SUMMARY concedes the demand for larger, brighter displays and the resulting heat load ("200 Watts or more of power through such a display window is common"). KSR expressly recognizes market demand as a legitimate motivation. A POSITA facing a 70-inch outdoor display (as the '322 touts) would combine directed rear-surface airflow (Kim/Kimura) with a plate-and-aperture arrangement (Kim/Na) to manage that heat.

5. Known technique, finite number of predictable solutions. Drawing vs. forcing air (Kim teaches both), brackets vs. integral walls for spacing, and providing apertures in a cover for access are all known mechanical expedients with predictable outcomes. KSR: where a technique is known to improve one device, applying it to a similar device in the same way is obvious.

6. Reasonable expectation of success / no teaching away. Both Kim and Kimura report successful backlight cooling; neither criticizes the other's approach. MRI argued teaching away (Kim's "porous" cover; Na's and Cho's finned/heat-sink designs; Kimura's uniform-cooling goal), but the Board rejected those arguments, and the CAFC affirmed on substantial evidence.

7. The claims' own "majority" and "substantially parallel" limitations do not rescue them. Kimura's express goal of cooling "the entire backlight unit … uniformly" supplies the motivation to size the plate across the rear ("majority"), and Kim's cover is expressly "substantially parallel." These are the two limitations MRI leaned on most, and both are met by the references' own disclosures, not by hindsight.

8. The Patent Owner's counterarguments — and why they failed

The record shows MRI ran a three-front defense; each was rejected at the Board and survived CAFC review:

• "Constricted convection plate" not disclosed. MRI argued Kim's shield cover is porous/perforated (through which air passes) rather than a solid plate defining a channel, and that the Board's construction was too broad. The Petition/Board responded that the cover confines and guides the airstream across the backlight, satisfying the claim, and the CAFC held substantial evidence supports the finding as to both Kim and Na.
• "Access apertures" (claim 8). MRI sought a narrow reading limited to hardware-access openings that are plugged during operation. The Board refused, because the specification makes plugging optional; the CAFC affirmed.
• Objective indicia (commercial success / copying). MRI offered evidence of Samsung's commercial success and alleged copying. The Board gave it little/no weight, finding no nexus and crediting evidence that Samsung designed its accused cooling system before the alleged tear-down. The CAFC affirmed. (This is the Graham fourth factor, and its failure is decisive for the secondary-considerations defense.)

Net effect: every independent claim was invalidated, the invalidation was affirmed on the merits, and the most plausible objective-indicia arguments were found unnexused to the claimed subject matter.

9. The three unchallenged claims (6, 14, 15) — residual § 103 exposure

These were not adjudicated (they sit outside the Samsung challenge set). But they are dependent claims hanging off canceled independents, so they cannot be infringed without practicing a canceled claim — and, in any event, they too appear obvious on the available art:

• Claim 6 (← 4): "a thermoelectric unit in gaseous communication with the air being drawn by the fan."
  The '322 specification itself describes thermoelectric modules as known, off-the-shelf devices: "For applications which require both heating and cooling, a thermoelectric module may be used as the refrigeration unit 110. Thermoelectric modules are commonly available which can run in both cooling and heating modes." Combining the kim/hong channel with a known thermoelectric cooler placed in the airflow path is the substitution of a known element for a known function with a predictable result — squarely obvious under KSR. Examiner-cited art in the same family (US 6,536,266, Rockwell Collins "Closed loop LCD heater system"; US 4,634,225, GE "Transflective liquid crystal display with integral heating unit") corroborates that temperature-conditioning modules in display airflow were routine.

• Claims 14 & 15 (← 9): a gaseous closed loop "traveling across the front display surface, behind the constricted convection plate, and returning to the front display surface," with a propelling means (plurality of fans) and a cooling means.
  This is the isolated-gas front-surface cooling loop that appears throughout MRI's own family (the '322's own FIG. 9 and specification describe gas chamber 104, return air passage 106, front glass 108, and refrigeration unit 110), and that is the subject of related MRI applications (US 2009/0126914; US 2009/0126907; and the parent US 8,854,595 family). Independent of MRI's own disclosures, WO 2005/079129 (Inssimainos, "controlling the temperature of a display surface") and US 2006/0092266 (NEC, projection display using liquid and air cooling) show front-surface gas-film temperature control, and the '322 specification itself incorporates by reference an air-curtain application (Ser. No. 11/941,728) — an admission that front-surface gas curtains were known. Caveat: MRI's own Sep-2008 filings postdate the 2008-03-03 priority and so may not themselves qualify as § 102 art; but the external art (Inssimainos, NEC) and the known-technique rationale still support obviousness. I present this as an obviousness theory, not a holding — claims 14/15 were never tested.

10. Discrepancies, gaps, and sourcing flags

1. Ground-numbering discrepancy (flag). The previously generated PTAB challenges section lists eight grounds (Kim/Na/Kimura families). However, the Patent Owner Response contains a heading "Ground 12: Cho Does Not Render Obvious Claims 4, 5, 9, 10, and 11" and a related passage on Cho's upper plate 513 / heat sink 530 / cooling fan 520. This indicates the Petition likely presented more than eight grounds (or a separately numbered Cho-based ground not captured in the earlier table). I have treated Cho as an additional/alternative plate-over-chassis ground rather than inventing a numbering; the operative fact — all challenged claims held unpatentable — is unaffected. Recommendation: reconcile against the FWD's ground list.

2. Partial snippet conflict (minor). One retrieved exhibit snippet reads "Ground 3 – Claims 4 and 7 are patentable over Kim and Hong," which conflicts with the Petition's own heading "GROUND 1 – CLAIMS 4 AND 7 ARE OBVIOUS OVER KIM IN VIEW OF HONG." I treat the snippet as a garbled/derivative transcription and rely on the Petition heading, which is internally consistent with the Reply ("A. Ground 1: Kim in View of Hong Renders Claims 4 and 7 Obvious").

3. Secondary-reference content not verified. My descriptions of Tachikawa (bracket/mounting), Hong (PCB-based LED backlight), and Takahashi (access apertures) are drawn from the parties' own headings and the Petition's element tables, not from the references' full texts, which I could not retrieve in this session. The claim-mapping conclusions are robust to that gap because the primary references (Kim, Na, Kimura) independently supply the constricted plate, the fan, the parallel orientation, and the aperture/majority limitations at issue.

4. FWD text not directly reviewed. The FWD's internal page-pin cites are not reproduced; the mapping above is anchored in the Petition, PO Response, and Reply, which agree on the reference/limitation assignments.

5. Effective-date conclusion is hedged. The pre-AIA/AIA determination for § 103 is stated as "appears to," because it turns on the validity of the 2008 priority chain — a question outside this analysis. The substantive Graham/KSR test is unchanged either way.

Bottom line

Every independent claim of US 9,173,322 is obvious under § 103 over combinations of ordinary display-cooling art, and that conclusion has already been adjudicated and affirmed:

• Claim 4 (and dependents 2-family features) → Kim (US 7,800,706) + Hong — Kim's shield cover 140 behind backlight 130 with fan 210 drawing external air through the confined space is the claimed constricted-convection arrangement; Hong supplies the PCB/LED backlight. Motivation: same field, common problem, predictable confinement-of-airflow result, no teaching away.
• Claim 1 (and 2, 3) → Kim + Tachikawa — Kim's cover/fan plus Tachikawa's bracket; brackets are a known spacing expedient, and channel width is an admitted design variable.
• Claim 9 (and 10–13, 16) → Na (alternatively Kimura) — a plate-and-fans arrangement behind an LED backlight, with Kimura's "uniform, entire-backlight" teaching supplying the motivation to size the plate across the majority of the rear surface.
• Claim 8 → Kim + Hong + Takahashi, or Na's through-holes; MRI's narrow "access apertures" construction was rejected.
• The defense that failed: MRI's teaching-away and objective-indicia arguments. No nexus was established, and Kimura's own goal defeated the teaching-away theory.

The Board invalidated claims 1–5, 7–13, and 16 on 2024-06-18; the Federal Circuit affirmed on 2026-03-31. The only claims never adjudicated — 6, 14, 15 — are dependent on canceled independents and, on the analysis above, would themselves be obvious over the '322's own admissions plus known thermoelectric and front-surface-gas-curtain art. Net: the patent no longer supports any viable § 103 defense-of-validity position.
