Unified Patents, LLC v. Ideahub Inc.

Case Overview & Background

A threshold characterization point: despite the framing of "patent infringement litigation," this matter is not infringement litigation — no federal district court complaint, no accused product, and no damages claim. Per Unified Patents' own announcement and the case metadata, this is an ex parte reexamination proceeding at the USPTO (Central Reexamination Unit) in which Unified Patents, LLC acts as third-party requester against U.S. Patent 10,212,422, owned by Ideahub Inc. The filing date of August 28, 2026 is consistent with the current date (September 7, 2026) and is corroborated by Unified's public post of August 31, 2026; the "date inconsistency" flag in the prior case summary appears to be a stale artifact.

Parties and procedural posture. Unified Patents, LLC is a Washington, D.C.-based patent risk-management firm (a defensive, member-funded organization, not an operating company) that challenges patents it views as assertion risks — here through its "SEP Video Codec Zone" campaign against standard-essential patent (SEP) licensing entities. Unified says it has filed 240+ IPR petitions over eight years against NPE-controlled patents. Ideahub Inc. is a Korean patent monetization firm (NPE/PAE) founded in 2016 by Kyeong-su "Keith" Im, a former TiVo/Rovi senior director; it acquires and licenses patent portfolios (much of it originated by Korea's Electronics and Telecommunications Research Institute, ETRI), declares patents essential to video codec standards, and reportedly is preparing a KOSDAQ IPO. Ideahub's subsidiary ImberaTek LLC has separately sued Apple (W.D. Tex., 1:24-cv-00129) and previously Samsung in E.D. Tex. In the reexamination, Unified is represented by in-house counsel TJ Murphy and Jessica L.A. Marks (per Unified's announcement). Because this is an ex parte reexamination under 35 U.S.C. §§ 301–307, the proceeding runs between Ideahub (patent owner) and the USPTO examiner, with the third-party requester's participation rights sharply limited; the threshold question is whether the request raises a "substantial new question of patentability," with appeal routes through the PTAB and then the Federal Circuit. No USPTO reexamination control number or CRU decision had surfaced in publicly retrievable sources as of this writing, and no substantive outcome exists yet.

Patent, technology, and why it matters. The '422 patent (titled "Method and apparatus for encoding video, and decoding method and apparatus," claiming priority back to a 2010-08-17 Korean application from the ETRI inventor group) is directed to video encoding/decoding in which quantization parameters are set and predicted adaptively based on block information of the encoding/decoding object block — e.g., deriving a block's quantization parameter from larger, previously decoded, or neighboring blocks so that QP signaling can be reduced. Unified describes the patent as designated essential to the VVC/H.266 standard and enrolled in Access Advance's VVC patent pool, with a related European family member asserted in litigation there. The practical "accused technology" is therefore not a specific product but the VVC-compliant video coding ecosystem (streaming platforms, broadcast, chipsets, and consumer devices) that would owe pool royalties. The case is notable because it is the latest salvo in Unified's sustained validity campaign against Ideahub's codec SEP portfolio: Unified previously secured invalidation of Ideahub's U.S. 9,641,849 (IPR2020-00702, affirmed by the Federal Circuit in 2023), all claims of U.S. 11,122,274 (PGR2022-00044, affirmed by the Federal Circuit on April 10, 2026 in Case 24-1684), filed a January 2025 ex parte reexamination against the related VVC patent U.S. 10,904,539, and saw Ideahub's ETRI-origin EP 3402195 fully revoked at the EPO (appeal confirmation November 2025). The '422 patent shares technical lineage with EP 3402195 — both concern adaptive quantization-parameter derivation — so this reexamination extends an established anti-NPE pattern while testing claims that sit at the intersection of VVC standardization, pool licensing economics, and Ideahub's monetization/IPO ambitions.

Sourcing note: Party characterizations, prior IPR/PGR results, the EPO outcome, and counsel names are drawn from Unified Patents' public insight pages (unifiedpatents.com), the Federal Circuit judgment in Ideahub Inc. v. Unified Patents, LLC, No. 24-1684 (Fed. Cir. Apr. 10, 2026, per curiam affirmance), a Finnegan PTAB blog analysis of PGR2022-00044, and RPX/Mondaq reporting on ImberaTek/Ideahub. Details of the '422 patent come from USPTO public records via uspto.report and family listings. The specific reexamination control number, the CRU's SNQ decision, and any Patent Owner response had not been published in the sources retrieved; the August 31, 2026 Unified post describes the filing but does not provide a control number or status update beyond the filing itself.

Key Legal Developments & Outcome — Unified Patents, LLC v. Ideahub Inc.

Threshold correction (applies to the whole task)

There is no patent infringement litigation here, and therefore most of the requested categories (complaint/answer, motion practice, Markman, discovery, trial, verdict, JMOL, fees) are structurally inapplicable. The matter is a USPTO ex parte reexamination of U.S. Patent 10,212,422 under 35 U.S.C. §§ 301–307, filed by Unified Patents, LLC as third-party requester against patent owner Ideahub Inc. As of today (2026-09-07), the proceeding is 10 days old and pending at the threshold "substantial new question of patentability" (SNQ) stage. There are no docketed post-filing events, no CRU order, no control number published, and no substantive outcome. The developments below are organized chronologically and by the closest analogue to the requested categories; district-court categories are marked N/A rather than left silent.

---

1. Filing & initial pleadings

• 2026-08-28 — Unified Patents filed an ex parte reexamination request against U.S. Patent 10,212,422, owned by Ideahub Inc. The request challenges the '422 patent, which is directed to video encoding/decoding that adaptively sets/predicts quantization parameters based on block information of the encoding/decoding object block; the patent is designated essential to the VVC/H.266 standard and enrolled in Access Advance's VVC patent pool, and a related family member has been asserted in European litigation. Unified is represented by in-house counsel TJ Murphy and Jessica L.A. Marks. (Source: Unified Patents insight post, "IdeaHub H.266 / VVC codec patent challenged," dated 2026-08-31 — https://www.unifiedpatents.com/insights/2026/8/31/another-ideahub-video-codec-patent-challenged)
• No "complaint," "answer," or "counterclaims" exist — in an ex parte reexamination there is no answer or pleading practice. Ideahub's first substantive right of response arises only after the CRU grants the request, when it may file a patent owner statement under 37 C.F.R. § 1.530. None has been filed because no order has issued.
• No USPTO reexamination control number (90/xxx,xxx) has surfaced in public sources as of this writing; Unified's announcement itself provides no control number or portal link. (Sourcing note: by contrast, Unified's analogous reexamination of Ideahub's related VVC patent 10,904,539 was publicized with portal control number 90/019,837.)

2. Pre-trial motions of substance (MTD, transfer, stay, SJ)

• N/A — not a district court case. No motion to dismiss, transfer motion, or summary-judgment practice exists in this forum. The only threshold "motion-equivalent" is the CRU's sua sponte SNQ determination under 35 U.S.C. § 303(a), which must be made within three months of the request (statutorily, "within three months"; the CRU often acts faster). No § 303 order has issued as of 2026-09-07.
• A stay pending IPR concept is inapplicable; there is no parallel district court litigation over the '422 itself identified in any source.

3. Claim construction (Markman)

• No Markman hearing or order — none possible at this stage.
• Relevant substantive point for future development: if the CRU orders reexamination, claims are construed in ex parte reexamination under the broadest reasonable interpretation standard (the Phillips framework does not govern examiner practice). No construction has been issued or published.

4. Discovery milestones

• None. In an ex parte reexamination the third-party requester (Unified) has no discovery rights and sharply limited participation: it may file a request and, after the order, one written comment on the patent owner's statement (35 U.S.C. § 304; 37 C.F.R. § 1.535). All substantive prosecution thereafter runs between Ideahub and the examiner. No depositions, document production, or expert discovery exist in this track.

5. Trial events, verdict, post-trial motions

• None — there is no trial. The closest analogues — the CRU's examination, a patent owner response (due ~2 months after the SNQ order), examiner action, and any requester comment — have not yet occurred. Timeline analog: Unified's reexamination of Ideahub's 10,904,539 was filed 2025-01-31 and the CRU granted the SNQ order on 2025-03-07 (about five weeks). If that cadence repeats, a CRU order on the '422 could be expected in late September to mid-October 2026 — but this is inference, not a recorded event, and nothing is docketed. (Source: Unified Patents, "IdeaHub video codec patent challenge instituted," 2025-03-07 — https://www.unifiedpatents.com/insights/2025/3/7/ideahub-video-codec-patent-challenge-instituted)

6. Settlement, dismissal, judgment, appeal — final disposition / present posture

• No disposition of any kind. Present posture (2026-09-07): request pending before the Central Reexamination Unit on the SNQ threshold. Possible future routes if reexamination is ordered and claims are rejected: Ideahub may appeal to the PTAB and then the Federal Circuit under 35 U.S.C. § 306/§ 145; if the CRU declines to order reexamination, Unified's only recourse is a mandamus-style challenge, which is rarely granted.
• No judgment, settlement, or fee award exists. Ex parte reexaminations are not "settled" in the district-court sense, though the parties' broader dispute history (below) shows an adversarial, non-settling posture between Unified and Ideahub across multiple forums.

7. Parallel PTAB/IPR-PGR proceedings and related litigation affecting this case

No IPR/PGR has been filed against the '422 patent itself. However, this reexamination is the latest step in an established, closely-related campaign, and those parallel matters frame its significance:

• IPR2020-00702 (U.S. 9,641,849) — Unified's earlier Ideahub challenge; all claims held unpatentable; affirmed by the Federal Circuit (2023). (Per Unified's Ideahub tag page — https://www.unifiedpatents.com/insights/tag/Ideahub)
• PGR2022-00044 (U.S. 11,122,274) — filed 2022-06-09, instituted 2023-02-06, final written decision of unpatentability on 2024-02-05; affirmed by the Federal Circuit in Ideahub Inc. v. Unified Patents, LLC, No. 24-1684, per curiam affirmance entered 2026-04-10 (Judges Hughes, Stoll; Judge Seeborg sitting by designation). (Sources: Justia CAFC judgment — https://law.justia.com/cases/federal/appellate-courts/cafc/24-1684/24-1684-2026-04-10.html; PTAB case data on PGR2022-00044)
• Ex parte reexamination 90/019,837 (U.S. 10,904,539) — the direct sibling proceeding: filed 2025-01-31, CRU SNQ order on 2025-03-07; this '539 patent is a fellow VVC/Access Advance Ideahub patent, and the '422 reexamination mirrors it procedurally.
• EPO revocation of EP 3402195 — the European family member technically closest to the '422 (both concern adaptive quantization-parameter derivation); complete revocation of all claims was confirmed by the EPO Board of Appeal on 2025-11-06.
• District-court enforcement by Ideahub affiliates (context only): Ideahub's subsidiary ImberaTek LLC has sued Apple in W.D. Tex. (1:24-cv-00129), and Ideahub-related entities (e.g., AX Wireless, Helios Streaming) have pursued district-court assertions of other portfolios. No source identifies the '422 patent itself as asserted in any U.S. district court action; Unified states only that "a related patent was asserted in Europe." Unified separately filed ex parte reexaminations against AX Wireless Wi-Fi patents (U.S. 10,917,272 and 11,777,776) on 2026-02-26 — an affiliated-entity matter, not the '422.

Effect on the present proceeding: none yet. These prior outcomes establish a track record (including Federal Circuit affirmance and EPO revocation of the closest technical sibling) that likely informed the '422 request's prior-art position, but they have no preclusive effect on the CRU's independent SNQ determination. The CRU has not yet acted, and no party has filed anything since the 2026-08-28 request.

---

Bottom line / outcome

No outcome exists. As of 2026-09-07, the only confirmed development is the filing of the ex parte reexamination request on 2026-08-28 (publicly announced by Unified on 2026-08-31). Everything else in the district-court "litigation" checklist is N/A by case type. The next observable milestone will be the CRU's § 303 SNQ order — expected within the statutory three-month window and, based on the analogous '539 reexamination's five-week turnaround, possibly in late September/October 2026 — followed, if granted, by Ideahub's patent owner statement. Those events are not yet recorded in any public source, and no reexamination control number has been published for this matter.

Counsel of Record — Unified Patents, LLC (Requester/"Plaintiff")

Threshold caveat (same as prior sections): This is not a district court patent infringement case — it is a USPTO ex parte reexamination of U.S. Patent 10,212,422 (35 U.S.C. §§ 301–307), filed by Unified Patents, LLC as third-party requester on 2026-08-28. There is therefore no PACER docket, no formal "appearance" practice, and no lead/back-up counsel designations as in IPR or district-court litigation. Unified's own public announcement of the filing (2026-08-31) is the only authoritative source identifying counsel for this specific proceeding, and it names two in-house attorneys only — no outside/local counsel has been identified for the '422 matter. No reexamination control number has yet been published, so no USPTO filing receipt or attorney-power list is publicly retrievable.

1. TJ Murphy (Timothy J. Murphy)

• Role: In-house counsel for Unified Patents, LLC (requester); identified by Unified as its representative "in this proceeding." In prior PTAB matters he has served as lead counsel for Unified (e.g., designated lead in IPR2022-01500).
• Firm / office: Unified Patents, LLC — 4445 Willard Ave., Suite 600, Chevy Chase, MD 20815 (USPTO Reg. No. 62,585; email tj@unifiedpatents.com). USPTO OED directory (updated 2026-04-05) confirms firm affiliation with Unified Patents, LLC, Chevy Chase, MD.
• Experience note: Unified in-house PTAB/reexamination practitioner who has repeatedly paired with Jessica L.A. Marks on Unified's ex parte reexamination and IPR filings against NPE-owned patents (e.g., Factor2 Multimedia and Stasit matters). Careful: he is a different person from Boston-based Timothy M. Murphy (Sunstein/Nutter) — do not conflate the two.

2. Jessica L.A. Marks

• Role: In-house Senior Patent Counsel, Unified Patents, LLC (Reg. No. 67,451); has served as lead counsel for Unified in PTAB proceedings (per USPTO PTACTS mandatory-notice filings in IPR2020-00983 et al.).
• Firm / office: Unified Patents, LLC — P.O. Box 53345, Washington, DC 20009 (phone 202-847-5260; jessica@unifiedpatents.com).
• Experience note: Former Finnegan, Henderson associate (10+ years) litigating post-grant proceedings, district-court cases, and ITC investigations (electrical/image-processing/video technologies among others); at Unified she has led the Ideahub validity campaign — including the directly parallel ex parte reexamination of Ideahub's related VVC patent U.S. 10,904,539 (90/019,837, instituted 2025-03-07), where she was in-house counsel alongside Haynes and Boone's Dagim Tilahun and Jon Bowser. J.D. University of Maryland (Carey) School of Law; B.A./M.B.E. University of Pennsylvania.

If the CRU order later issues, the control number and any updated power-of-attorney will become the best confirmation source; as of today the Unified announcement is the only record of counsel.

Counsel of Record for Ideahub Inc. — Threshold Findings

No counsel of record for Ideahub Inc. has appeared in this proceeding as of 2026-09-07. This is not a matter of sealed filings — there is nothing to seal, and no appearance to make yet. Three structural points explain why, and they matter for how the "defendant's counsel" question should be read:

1. There is no "defendant." This is not patent infringement litigation with a complaint, answer, and counsel of record on a PACER docket. It is an ex parte reexamination (35 U.S.C. §§ 301–307) at the USPTO Central Reexamination Unit. Unified Patents, LLC is the third-party requester; Ideahub Inc. is the patent owner. Neither maps cleanly onto plaintiff/defendant.
2. The case is 10 days old and pending at the SNQ threshold. Unified filed the request on 2026-08-28. No reexamination control number has been published, no § 303(a) "substantial new question" order has issued, and no patent owner statement under 37 C.F.R. § 1.530 has been filed or is even due yet.
3. In ex parte reexamination, the patent owner's counsel does not "enter an appearance" up front. Ideahub's first right of participation arises only after the CRU grants the request, when it files its patent owner statement and (typically) a power of attorney designating its practitioners. Nothing like that has occurred. (Requester's counsel — Unified in-house attorneys TJ Murphy and Jessica L.A. Marks — are the only attorneys publicly identified in connection with the filing, per Unified's 2026-08-31 announcement.)

---

Known Ideahub counsel in closely related proceedings (context only — NOT counsel of record here)

Because no appearance has occurred, the best-grounded answer identifies the lawyers who have actually represented Ideahub before the USPTO/PTAB and the Federal Circuit in the directly parallel matters — the pool from which any future § 1.530 counsel would most plausibly come. I cannot confirm any of them has been retained for the '422 reexamination; do not treat this list as counsel of record.

---

Bottom line

• No Ideahub attorney is counsel of record in the '422 reexamination, and no PACER-style docket, docket entry, or firm announcement identifies one. If filings were sealed — they are not — I would say so; the absence here is procedural, not confidentiality-driven.
• The next observable milestone for any Ideahub counsel designation is the CRU's § 303 order. If granted (the analogous '539 reexamination was ordered ~5 weeks after filing), Ideahub will have ~2 months to file a patent owner statement under 37 C.F.R. § 1.530, at which point its power of attorney and counsel names will appear in the public reexamination file.
• Historically, Ideahub's USPTO-side defense has been run by Sughrue Mion (Kiblawi/Mandir team) and its Federal Circuit appeals by Mintz Levin (Newman team) — both are strong candidates to appear later, but that is inference from parallel dockets, not a verified fact for this case. The only attorneys affirmatively tied to this specific proceeding are Unified's in-house counsel (TJ Murphy and Jessica L.A. Marks), who represent the requester, not Ideahub.
