Unified Patents v. LG Electronics Inc.

Case Overview: Unified Patents v. LG Electronics Inc., IPR2025-01099

This case involves an Inter Partes Review (IPR) proceeding initiated by Unified Patents against LG Electronics Inc. before the Patent Trial and Appeal Board (PTAB), concerning the validity of U.S. Patent No. 10,306,667. This is not a patent infringement litigation, but rather a challenge to the patentability of claims within the '667 patent. The PTAB declined to institute the IPR, citing procedural grounds. [cite: IPR metadata]

Unified Patents is a member-based organization focused on deterring frivolous patent litigation and reducing assertions by Non-Practicing Entities (NPEs), also known as patent trolls. They achieve this by directly challenging the validity of patents, primarily through IPRs at the PTAB. LG Electronics Inc., the patent owner in this proceeding, is a major South Korean multinational corporation globally recognized for its consumer electronics, home appliances, and various technology products, including televisions. The specific product or technology allegedly infringing patent 10,306,667 is not publicly detailed in relation to this IPR. While LG is frequently involved in patent litigation as both a plaintiff and defendant across its diverse product lines, no specific district court case where LG Electronics has asserted patent 10,306,667 could be identified through public searches.

The patent at issue, U.S. Patent No. 10,306,667, titled "METHOD AND APPARATUS FOR PROVIDING ENCODING/DECODING PICTURE BASED ON DEPTH MAP," generally relates to systems and methods for efficiently encoding and decoding pictures using depth map information. This technology is relevant in fields such as 3D video processing, virtual reality, and augmented reality, where depth information enhances the visual experience.

The procedural posture of this case is before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO). The PTAB is a specialized administrative court that provides a faster and often less costly alternative to district court litigation for challenging patent validity. A key aspect of PTAB proceedings is the institution decision, where the Board determines whether to proceed with a full review of the patentability challenge. The Director of the USPTO has significant discretion in these decisions and, as of late 2025, personally reviews and issues institution decisions, often in summary notices without detailed explanations for routine cases. In this particular instance, the IPR was "Not Instituted" on "procedural grounds." [cite: IPR metadata] This means the petition failed to meet a preliminary requirement, rather than being denied on the merits of the prior art arguments. Common procedural reasons for non-institution can include statutory bars (e.g., related litigation or time limits), failure to identify real parties-in-interest, or other discretionary factors exercised by the Director, often related to parallel litigation or workload management. The specific detailed reason for the procedural denial of IPR2025-01099 is not readily available in public summaries, reflecting the current practice of issuing concise notices. This non-institution is a victory for LG Electronics, as its patent claims avoid review and potential invalidation by the PTAB.

The IPR proceeding IPR2025-01099, filed by Unified Patents against LG Electronics Inc. regarding U.S. Patent No. 10,306,667, was not instituted on procedural grounds. [cite: IPR metadata] This means the petition failed to meet a preliminary requirement rather than being denied on the merits of the prior art arguments. Common procedural reasons for non-institution can include statutory bars (e.g., related litigation or time limits), failure to identify real parties-in-interest, or other discretionary factors exercised by the Director of the USPTO. [cite: IPR metadata]

The Director of the USPTO now personally reviews and issues institution decisions, often in summary notices without detailed explanations for routine cases, a policy that became effective as of October 20, 2025. This consolidation of control over institution determinations and the introduction of summary notices have contributed to a more restrictive, policy-driven approach to IPR institution, leading to lowered institution rates in 2025.

While the specific detailed reason for the procedural denial of IPR2025-01099 is not readily available in public summaries, it aligns with this shift towards more concise notices and increased discretionary denials by the Director. [cite: IPR metadata, 5, 8, 10] For example, the PTAB has shown a willingness to deny IPR institution when parallel district court litigation is well underway, especially if the district court is likely to resolve the validity issues first, using factors established in Fintiv decisions. Proposed rules in October 2025 also indicated that the Office would not institute an IPR when a petitioner intends to pursue invalidity challenges in other venues or if a pending proceeding involving the patent will reach a decision on validity before the Final Written Decision would be due.

Furthermore, issues concerning the identification of real parties in interest (RPIs) have also been a basis for procedural denials. For instance, in a precedential decision in March 2026, the USPTO Director denied institution of an IPR against an LG Display Co., Ltd. patent, finding that a foreign government as a real party in interest rendered the petitioner ineligible under the America Invents Act (AIA) because foreign governments are not "persons" entitled to file IPR petitions. This decision also noted the petitioner's failure to disclose all RPIs and rebut evidence of foreign sovereign involvement. While there's no indication that this specific RPI issue was the reason for IPR2025-01099's denial, it illustrates the types of procedural grounds that can lead to non-institution.

For LG Electronics, the non-institution of this IPR is a favorable outcome as it means its patent claims for U.S. Patent No. 10,306,667 will not undergo review and potential invalidation by the PTAB in this proceeding. [cite: IPR metadata]

I'll search for press coverage from several angles.

Let me search additional angles — the patent number, the parties, and industry coverage.

Let me check a few more angles, including the patent itself and any commentary on the batch denial.

Press and analyst coverage

I could not locate any press or analyst coverage of this proceeding — no Reuters, Bloomberg Law, Law360, Ars Technica, The Verge, IPWatchdog, Patently-O, EFF Deeplinks, JD Supra, or trade-press article reports on IPR2025-01099, on a Unified Patents v. LG Electronics dispute over U.S. Patent 10,306,667, or on any Director ruling resolving it. I searched the case number, the full caption, both party names in combination, the '667 patent number, and the patent's title ("Method and Apparatus for Providing Encoding/Decoding Picture Based on Depth Map"). The only hits were USPTO/PTAB primary-source documents (petitions, mandatory notices, Director Review orders) and law-firm or bar-association PTAB practice materials that do not mention this docket. There is no reported damages figure, settlement, verdict, or market-impact analysis to summarize, because this is an administrative institution decision rather than a damages action — and it appears to have gone entirely unremarked in the press. Reporting in this space is likewise scarce in general: even the PTAB's mass discretionary denials of late 2025, which are the practice context for a "not instituted" outcome, appear in practitioner updates rather than news coverage.

The closest adjacent items are roundups, not case coverage. Sheppard Mullin published an analysis (dated April 10, 2025) of the Federal Circuit's estoppel/standing decision in the Gesture Technology Partners appeals, a case in which Unified Patents and LG Electronics both appear — but it concerns U.S. Patent 7,933,431 and the Gesture litigation, not the '667 patent or this docket. The New York Intellectual Property Law Association's PTAB Committee monthly updates and a later NYIPLA PTAB deck track Director Review decisions, Fintiv practice, and the falling institution rate, and a Kilpatrick Townsend PTAB roundup surveys RPI-based dismissals and "de-institution" after final written decisions. These describe the legal environment in which a denial like this would occur; none names IPR2025-01099, Unified Patents, or LG Electronics in connection with it.

One caveat carried forward from the earlier sections, now reinforced by the absence of press coverage: the docket number "IPR2025-01099" in the public record is tied to a Harbor Freight Tools USA v. Champion Power Equipment family matter over a generator-related patent — and the PTAB papers retrieved reference U.S. Patent 11,306,667, not 10,306,667. If that is correct, the reason no outlet has covered "Unified Patents v. LG Electronics, IPR2025-01099" may simply be that no such proceeding exists under that number. That conflict should be resolved against the PTAB Portal before any of this case's sections are treated as settled. I am reporting a genuine absence of coverage, not a search failure: nothing in the retrieved results supports a single news citation about this case.

I'll research petitioner-side (Unified Patents) counsel of record, starting with searches on the docket number itself and Unified Patents' standard PTAB representation.

The searches show Unified Patents uses in-house PTAB counsel plus outside firms. Let me pin down current (2025) petitioner-side representation and verify the docket/patent discrepancy.

Now let me verify the docket number and patent directly, since prior sections flagged a conflict.

Petitioner ("Plaintiff") Counsel of Record — IPR2025-01099

Threshold issue: the "plaintiff" in this docket is not Unified Patents

Before naming anyone I have to flag a conflict, because it determines whether any of the names below are actually counsel of record in this case.

The public record for IPR2025-01099 is not captioned Unified Patents v. LG Electronics. The docket as it exists on the Board's systems is GENERAC POWER SYSTEMS, INC. et al. v. Champion Power Equipment, Inc., involving U.S. Patent No. 11,306,667 ("dual-fuel selector switch"), with petitioners Generac Power Systems, Inc., Harbor Freight Tools USA, Inc., and MWE Investments, LLC. The case terminated by joint request under 35 U.S.C. § 317(b) / 37 C.F.R. § 42.74(c) to treat the settlement agreement as business confidential. [Arctic Invent case page for IPR2025-01099, https://cases.arcticinvent.com/us/patent/us/joint-request-to-treat-settlement-agreement-as-business-confidential-i/ipr2025-01099/]

This corroborates — and sharpens — the conflict flagged in the two previously generated sections: the number's real caption is the Harbor Freight/Generac/MWE–Champion family over the '667 patent as 11,306,667, not 10,306,667, and there is no Unified Patents or LG Electronics anywhere in it. Per my operating instructions I treat the prompt's metadata (caption, case number, patents at issue) as authoritative for how this case is labeled, but I cannot manufacture a counsel list for a party appearance that does not exist in the docket bearing that number. I therefore give you (A) the petitioner-side counsel actually shown in the IPR2025-01099 public record, with confidence caveats, and (B) the documented petitioner-side counsel profile for Unified Patents, the nominal plaintiff.

---

A. Petitioner-side counsel appearing in the public IPR2025-01099 record (Generac / Harbor Freight / MWE — not Unified Patents)

The only attorney names I can tie to this docket come from the Board's own correspondence in the sibling Harbor Freight v. Champion filings. A November 20, 2025 Board email (Deputy Chief Clerk Andrew Kellogg) authorizing five pages of supplemental briefing, preserved as Exhibit 2120 in IPR2025-00805, went to attorneys at Merchant & Gould P.C. (T. Leach, T. Stemler; group address GeneracChampionJDG@merchantgould.com), Foley & Lardner LLP (M. Houston, J. Gundersen, K. Dodd), Ice Miller LLP (T. Walsh, T. Rammer, A. Siliunas), and a zpatents.com address associated with Champion Power Equipment. [Ex. 2120, IPR2025-00805, https://gaeflexstaging-dot-docketupdate.appspot.com/cases/PTAB/IPR2025-00805/.../Exhibit-2120-November_20_2025_email_from_TrialsUSPTOGOV_in_IPR2025_01099/]

Caveats you should treat as material:

• That email is a distribution/service list covering both sides; the retrieved text does not map any firm to petitioner or patent owner. I will not guess. The merchantgould.com group address is named for the Generac–Champion dispute, but a naming convention is not an appearance.
• I could not retrieve the § 42.8(b)(3) mandatory notices or power of attorney for IPR2025-01099 itself, which is where lead/back-up counsel and Reg. Nos. would be stated with precision.
• I have no full first names for these attorneys from the retrieved sources, so I am not reconstructing them.

---

B. Petitioner-side counsel of record for Unified Patents (the nominal "plaintiff"), as documented in its PTAB practice

There is no filing in any proceeding numbered IPR2025-01099 in which a Unified Patents attorney appears. What follows is Unified's documented counsel-of-record structure across its other IPRs, which is the best available evidence of who would sign a Unified petition. It is not an appearance in this docket.

In-house / Unified Patents, LLC (4445 Willard Ave., Suite 600, Chevy Chase, MD 20815; formerly 1875 Connecticut Ave. NW, Floor 10, Washington, D.C. 20009):

Outside firms Unified has retained as lead/back-up PTAB counsel (a rotating roster, not a fixed panel):

None of these appearances is in IPR2025-01099, and I am not attributing any of them to this case.

---

C. What I could not verify, and what it means for the answer

1. No Unified Patents–side counsel of record exists in IPR2025-01099 because no Unified Patents paper is indexed in that docket. If the metadata is right that the proceeding was not instituted, the ordinary explanation is also the simplest: in a case denied at the institution stage, petitioner's counsel may be the only counsel ever entered, and no patent-owner-side appearance occurs at all. But here the mismatch is upstream of that — the caption itself differs.
2. "PACER" is inapposite. This is a PTAB proceeding; the filing systems of record are PTAB E2E and PTACTS, not PACER. I found no district court action on U.S. 10,306,667 involving LG, consistent with the earlier section — so there is no litigation docket from which to borrow local counsel.
3. Nothing is sealed as to a petitioner appearance, but the operative power of attorney and mandatory notices for IPR2025-01099 were not retrievable in my searches, so I cannot state lead counsel's name with the certainty the question asks for.

D. Recommended verification (open items, not settled facts)

• PTAB E2E / PTACTS case page for IPR2025-01099 — pull the caption, patent number, and the § 42.8(b)(3) notices to get the actual lead/back-up counsel and Reg. Nos. (https://ptacts.uspto.gov).
• Docket Navigator or Lex Machina (PTAB module) — search Unified Patents, LLC as petitioner and LG Electronics as patent owner across 2025; if a differently numbered Unified-v.-LG IPR exists on the '667 (10,306,667) patent, its power of attorney will give you the answer the metadata implies.
• USPTO Patent Center / Assignment Search for U.S. 10,306,667 — confirm the current assignee before relying on the earlier sections' statement that LG owns it.

Bottom line: For the docket numbered IPR2025-01099, the petitioner side is Generac/Harbor Freight/MWE, and the only attorney names I can associate with that docket are the Merchant & Gould, Foley & Lardner, Ice Miller, and zpatents.com personnel on the Board's November 20, 2025 service distribution — with side assignments unverified. For the caption Unified Patents v. LG Electronics as given in the metadata, no counsel of record can be identified, because no such appearance exists in the public record under that number.

I'll research counsel for LG Electronics (the patent owner/respondent in this IPR, though the metadata labels it "defendant"). Let me run several searches.

Let me search the PTAB docket sources and patent ownership directly.

The docket search surfaced a discrepancy I need to run down, plus I need to confirm the '667 patent's owner and LG's PTAB counsel. Let me dig further.

Defendant / Patent-Owner Representatives — IPR2025-01099

Important framing note before the names: In this proceeding LG Electronics Inc. is styled in the case metadata as the "defendant," but an IPR is not a civil action. LG is the patent owner (respondent); Unified Patents is the petitioner. There is accordingly no "defendant's counsel" in the litigation sense — the relevant entry is the patent owner's counsel of record under 37 C.F.R. § 42.8(b)(3) (lead and back-up counsel), plus any in-house attorneys listed on a power of attorney.

Bottom line

I could not identify any counsel of record for LG Electronics in IPR2025-01099, and I found affirmative reasons to doubt that this docket, as described in the case metadata, exists in the public PTAB record. Two specific conflicts surfaced:

1. The docket number appears to belong to a different proceeding. PTAB E2E documents for IPR2025-01099 caption the case against U.S. Patent No. 11,306,667 — not 10,306,667 — in the Harbor Freight Tools USA Inc. et al. v. Champion Power Equipment, Inc. family of generator-patent IPRs. A Patent Owner paper filed in that docket refers to "Champion Patent Families," four parallel district court cases, and multiple IPR filings with Sotera stipulations. [PTAB E2E petition document 1558002, https://ptacts.uspto.gov/ptacts/public-informations/petitions/1558002/download-documents]
2. IPR2025-01099 appears to have been an active, instituted proceeding in late 2025, which is inconsistent with the metadata's "Not Instituted – Procedural" status. On November 20, 2025, the Board's Deputy Chief Clerk (Andrew Kellogg) emailed counsel in the case authorizing five pages of additional briefing per party on the impact of Revvo Technologies v. Cerebrum Sensor Technologies, IPR2025-00632, Paper 20 (Nov. 3, 2025), and Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 (Nov. 5, 2025). [Ex. 2120 in IPR2025-00805, https://gaeflexstaging-dot-docketupdate.appspot.com/cases/PTAB/IPR2025-00805/Harbor_Freight_Tools_USA_Inc._v._Champion_Power_Equipment_Inc/11-26-2025-Patent_Owner/Exhibit-2120-November_20_2025_email_from_TrialsUSPTOGOV_in_IPR2025_01099/] A separate Harbor Freight email in that same family states that IPR2025-01099 was "within the window for a Director Review request," alongside IPR2025-01121 and IPR2025-01228. [PTAB E2E, petition 1558002 email from Kellogg re: withdrawal authorization]

Per my operating instructions I treat the prompt's metadata as authoritative for party names, case number, and patents at issue — so I have not rewritten the case identity. But you should be aware that if you pull the docket sheet for IPR2025-01099 from PTAB E2E, it will very likely not show Unified Patents or LG Electronics. That likely explains the absence of any LG-side attorney names: I found no public filing in which any attorney appeared for LG Electronics in a proceeding numbered IPR2025-01099.

Why no LG counsel would ordinarily appear in a non-instituted IPR

Even taking the metadata at face value, the following is normal and is not evidence of a research gap:

• A patent owner's mandatory notices (§ 42.8(b)) and power of attorney are typically filed with the Patent Owner Preliminary Response or, at the latest, shortly after institution. Where the Director denies institution on procedural grounds (as the metadata describes), the patent owner may never have appeared at all, leaving no counsel of record.
• The petition itself lists only petitioner's lead and back-up counsel; it does not identify opposing counsel. So the only place LG-side counsel would surface is a PO filing — and none is publicly indexed.
• Since late 2025 the Director has been issuing institution decisions via summary notices, which frequently contain no counsel caption and no reasoning. [Case summary, above]
• No parallel district court action in which LG is a party on U.S. Patent 10,306,667 was located (consistent with the earlier section), so there is no local counsel to borrow from a litigation docket.

What can be said about LG Electronics' PTAB representation with confidence

I cannot attribute these attorneys to IPR2025-01099. What I can document is LG's actual, on-the-record PTAB patent-owner team in the same period, which is the best available proxy for who would appear if LG were the patent owner here:

Baker Botts L.L.P. — documented lead and back-up counsel for LG Electronics as Patent Owner in TCL Electronics Holdings Ltd. et al. v. LG Electronics Inc., IPR2023-00461 (U.S. Patent 7,839,452), per Patent Owner's Updated Mandatory Notices dated May 10, 2023 [https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1550905](/patent/1550905)/download-documents]:

Caveat: this table documents IPR2023-00461, not IPR2025-01099. Do not cite it as the appearance in this case.

One additional data point on LG's posture in Unified Patents-related matters, though again without counsel names in the retrieved text: LG Electronics Inc. and LG Electronics USA, Inc. appeared as respondents alongside Unified Patents, LLC, Apple Inc., and Google LLC in the Supreme Court petition Gesture Technology Partners, LLC v. Unified Patents, LLC, No. 24-1281, where a waiver of response was filed June 25, 2025 on behalf of "Respondents LG Electronics Inc. and LG Electronics USA Inc." [https://www.supremecourt.gov/DocketPDF/24/24-1281/[363860](/patent/363860)/20250625102117428_2025.06.25%20Waiver%20-%[201281](/patent/201281).pdf]. The snippet does not identify the signing attorney or firm, so I am not attributing it.

Counsel actually shown in the public IPR2025-01099 record (different case)

For completeness, and flagged as belonging to the Champion Power Equipment docket rather than to any Unified Patents/LG matter, the Board's November 20, 2025 email in IPR2025-01099 was distributed to attorneys at:

• Merchant & Gould P.C. — T. Leach, T. Stemler (plus a case-specific group address, GeneracChampionJDG@merchantgould.com)
• Foley & Lardner LLP — M. Houston, J. Gundersen, K. Dodd
• Ice Miller LLP — T. Walsh, T. Rammer, A. Siliunas
• zpatents.com — T.J. Z…, J.M.F. (Champion Power Equipment's in-house/outside patent counsel address)

[Ex. 2120, IPR2025-00805 (Nov. 26, 2025), cited above]

I am not mapping these firms to specific parties — that would require the docket sheet's mandatory notices, which I was not able to pull. I also note that no LG Electronics attorney appears anywhere in that distribution list, which is further evidence that the docket number in the metadata does not correspond to a Unified Patents v. LG Electronics case.

Recommended verification steps (not yet completed)

Because the public record contradicts the metadata on two points, treat the following as open items rather than settled facts:

1. PTAB E2E / Patent Trial and Appeal Board End-to-End case page for "IPR2025-01099" — confirm the real caption, patent number, and any § 42.8(b)(3) notices. (https://ptacts.uspto.gov)
2. Docket Navigator / Lex Machina PTAB module — search "IPR2025-01099" and separately search LG Electronics as patent owner with Unified Patents as petitioner in 2025 to see whether a differently numbered Unified Patents IPR against an LG patent exists (e.g., in the -01000 to -01300 range).
3. USPTO Patent Assignment / Patent Center for U.S. 10,306,667 — I could not verify the current assignee of the '667 patent from the sources retrieved; the earlier summary's statement that LG owns it should be re-checked against the face of the patent and the assignment record before relying on it.
4. PACER — no district court case asserting the '667 patent against LG was located; if one exists, local counsel would appear there.

Sealed/absent filings: No filings appear to be sealed as to any LG-side appearance; rather, no LG-side appearance is indexed at all. If the proceeding truly was not instituted on procedural grounds, the most probable explanation is that LG never filed a paper requiring a counsel caption.
