Unified Patents v. Nielsen Co US LLC

This Inter Partes Review (IPR) case, IPR2026-00310, involves petitioner Unified Patents challenging a patent owned by Nielsen Co US LLC before the Patent Trial and Appeal Board (PTAB).

Unified Patents is a member-based organization whose core mission is to promote innovation by deterring frivolous patent litigation and reducing assertions by Non-Practicing Entities (NPEs), often referred to as "patent trolls." It achieves this by challenging the validity of patents through various means, including filing IPRs, and operates independently of its members in selecting which patents to target. Unified Patents explicitly states it does not pay for purchasing or licensing patents from NPEs. On the other side, Nielsen Co US LLC is a global operating company specializing in audience measurement, data, and analytics for television, radio, and digital media, providing insights into consumer behavior across various platforms.

The IPR challenges the patentability of claims within US patent 12063402. A specific one-line technical sketch for this patent could not be definitively sourced from the available public information without direct access to a patent database. In an IPR, there is no "accused product" in the traditional sense of patent infringement litigation; instead, the petition directly questions the validity of the patent claims themselves based on prior art. The procedural posture of this case is before the Patent Trial and Appeal Board (PTAB), an administrative body within the USPTO, under case number IPR2026-00310, filed in 2026 and currently pending. PTAB proceedings, which are heard by panels of Administrative Patent Judges, are often considered a faster and more cost-effective avenue for challenging patent validity compared to district court litigation, applying a "preponderance of the evidence" standard for unpatentability.

This case is notable as it represents Unified Patents' ongoing strategy to improve patent quality and deter the assertion of what it deems "poor quality" or unsubstantiated patents, even when the patent owner is an operating company like Nielsen. While Unified Patents primarily targets NPEs, its activities extend to challenging patents held by operating companies if those patents are deemed problematic within the technology zones it monitors, such as those related to media measurement and data analytics. The filing of an IPR against a major industry player like Nielsen indicates a perceived vulnerability of the patent and aligns with Unified Patents' broader goal of reducing overall patent assertion risk in the market.

The Inter Partes Review (IPR) case, Unified Patents v. Nielsen Co US LLC, IPR2026-00310, concerning US Patent 12063402, is currently pending before the Patent Trial and Appeal Board (PTAB). As of May 30, 2026, the proceedings are in their early stages, and most key legal developments beyond the initial filing are not yet publicly available.

Key Legal Developments and Outcome

Given the recent filing of IPR2026-00310 in 2026 and its "Pending" status, there have been no significant legal developments such as claim construction, discovery, trial events, or final outcomes.

• Filing & Initial Pleadings:

  • Unified Patents filed an Inter Partes Review petition against US Patent 12063402 in 2026. The exact filing date is not explicitly available in public search results, but other IPRs with similar numbering sequences were filed in May 2026, suggesting a filing sometime in late April or May 2026.
  • As the case is pending, information regarding Nielsen Co US LLC's Patent Owner Preliminary Response or any subsequent pleadings is not yet publicly accessible.

• Pre-Trial Motions of Substance:

  • No institution decision by the PTAB has been issued yet. This decision is a critical juncture where the PTAB determines whether to proceed with a full IPR trial.
  • No motions to amend claims, motions for joinder, or other substantive pre-trial motions have been publicly reported for this specific IPR. Motions such as dismissal, transfer, or stay pending IPR are typical of district court litigation and are not directly applicable to the procedural posture of an IPR at this early stage.

• Claim Construction (Markman) Outcomes:

  • Inter Partes Review proceedings before the PTAB generally apply the "broadest reasonable interpretation" (BRI) standard for claim construction, rather than conducting "Markman" hearings characteristic of district court patent infringement cases. As the case is in its initial phase, no claim construction outcomes have been determined.

• Discovery Milestones:

  • Discovery in IPRs is generally limited compared to district court litigation. There have been no reports of significant discovery milestones or disputes for IPR2026-00310.

• Trial Events, Verdict, and Post-Trial Motions:

  • The case is far from an oral hearing or a Final Written Decision. Therefore, no trial events, verdicts, or post-trial motions (such as motions for judgment as a matter of law (JMOL) or new trial) have occurred.

• Settlement, Dismissal, Judgment, or Appeal:

  • The IPR is currently pending. No settlement, dismissal, final judgment, or appeal has been reached.

• Parallel PTAB IPR/PGR Proceedings and their Effect on the Litigation:

  • There is no publicly available information indicating parallel IPR or Post-Grant Review (PGR) proceedings specifically challenging US Patent 12063402.
  • However, the broader landscape of PTAB proceedings in 2026 is relevant to this IPR. In Q1 2026, PTAB petitions, particularly IPR petitions, saw a significant year-over-year decrease, attributed to a surge in discretionary denials that began in 2025 and stricter procedural changes by the USPTO Director.
  • Notably, in March 2026, USPTO Director John Squires issued a memorandum directing the PTAB to consider U.S. manufacturing activity—of both the patent owner and the challenger—when deciding whether to institute an America Invents Act (AIA) trial. This policy aims to strengthen the position of patent owners with domestic operations and could impact institution decisions for IPRs filed by entities without a U.S. manufacturing footprint. This new policy, along with proposed rules in October 2025 to limit IPR challenges, reflects a trend towards a more patent-owner-friendly forum at the PTAB. These policy changes and declining institution rates create a challenging environment for petitioners like Unified Patents.

I'll research counsel for the petitioner, Unified Patents, in IPR2026-00310.

Threshold issue: the caption in the case metadata conflicts with the public PTAB record

Before naming counsel, I have to flag a material discrepancy, because it determines whose counsel to look for.

• The case metadata you supplied captions this as Unified Patents v. Nielsen Co US LLC, IPR2026-00310, with Unified Patents as plaintiff/petitioner.
• Multiple public PTAB-tracking sources instead identify IPR2026-00310 as VideoAmp Inc. v. The Nielsen Company (US), LLC, challenging all 30 claims of U.S. Patent No. 12,063,402 under § 103 over Kerr alone and in combination with Dutton, Thomassen, and Parkes, with the petition arguing against discretionary denial (Arctic Invent case entry). Patsnap's litigation record for the '402 patent likewise lists the patentability challenge as "IPR2026-00310 · filed by VideoAmp Inc" (Patsnap case record for 1:25-cv-00408).

Per my operating rules I treat your metadata as authoritative for party names, so I present the Unified Patents answer first — but the VideoAmp-based identification is the one that matches the underlying petition content, and it should be verified against the PTAB docket before publication. I could not retrieve the PTAB E2E docket sheet, the petition's power of attorney, or a notice of appearance for IPR2026-00310 itself, so no attorney listed below is confirmed as an attorney of record in this specific proceeding.

---

A. If the petitioner is Unified Patents (per case metadata)

No power of attorney, mandatory notice, or appearance for IPR2026-00310 was locatable. Based on Unified Patents' standardized § 42.10(b) filings across dozens of IPRs, its practice is to designate in-house PTAB counsel, frequently with an outside firm of record:

Caveat: the above is inferred from Unified's filing pattern, not from a document in IPR2026-00310. If Unified is genuinely the petitioner, a P-TACTS pull of the petition's power of attorney would resolve the outside-firm question in one step.

B. If the petitioner is VideoAmp Inc. (per the PTAB-tracking sources)

Unified Patents' own PTAB case portal lists Fish & Richardson P.C. as "PET. COUNSEL" for the companion VideoAmp v. Nielsen IPR (portal.unifiedpatents.com/ptab/case/IPR2025-00556). The corresponding Delaware litigation team was:

C. Correction to the previously generated section

The earlier "Defendant representatives" section states that Nielsen is represented by Fish & Richardson and names Joseph Colaianni, David Hoffman, and Frank Scherkenbach. That is inconsistent with the docket in The Nielsen Company (US), LLC v. VideoAmp, Inc., 1:25-cv-00408 (D. Del.):

• VideoAmp (defendant there, i.e., the challenger) is represented by Fish & Richardson (Kazi, Reese) with Delaware counsel Morrison.
• Nielsen (the patent owner) is represented by Kelley Drye & Warren LLP (Steven Yovits, Douglas Lewis, Jason P. Greenhut, Andrew Wood) with Potter Anderson & Corroon LLP as Delaware counsel (David Ellis Moore, Bindu Ann George Palapura, Andrew Wood). See the 4/9/2025 pro hac vice order and the Patsnap counsel-of-record listing.

So in this IPR, Fish & Richardson would be petitioner-side counsel, not Nielsen's. Nielsen's PTAB counsel of record for the '402 patent has not appeared in any source I could retrieve.

D. What is confirmed vs. unconfirmed

• Confirmed: VideoAmp's district court team and Nielsen's district court team (D. Del. 1:25-cv-00408 docket); Fish & Richardson as VideoAmp's PTAB counsel in the earlier Nielsen IPRs (IPR2025-00555/-00556); the magistrate's § 101 R&R of Feb. 12, 2026 and the March 18, 2026 dismissal order holding the asserted '402 claims invalid, with a Federal Circuit appeal noted (D. Del. docket reports "Appeals 26-1668").
• Not confirmed: any attorney of record in IPR2026-00310 itself. No power of attorney, mandatory notice, or notice of appearance was retrievable from P-TACTS, PTAB E2E, or third-party dockets during this search; the proceeding appears to remain at the petition stage.
• Recommended verification: pull the petition's § 42.10(b) power of attorney and the Patent Owner's mandatory notices from P-TACTS/PTAB E2E; those two documents will definitively resolve both the petitioner-identity conflict and the counsel list.

I'll research counsel for the patent owner (Nielsen) in this IPR. Let me run several searches.

Key finding: search results conflict with the case metadata on the petitioner. Let me dig deeper.

⚠️ Threshold issue: party identification conflict

Before answering, I have to flag a material discrepancy between the case metadata and the public record I could retrieve.

Metadata says: Unified Patents v. Nielsen Co US LLC, IPR2026-00310.
Public records returned by search say: IPR2026-00310 is captioned VideoAmp Inc. v. The Nielsen Company (US), LLC, challenging all 30 claims of U.S. Patent No. 12,063,402 ("Methods and apparatus to correlate census measurement data with panel data") as obvious under § 103 over Kerr alone or in combination with Dutton, Thomassen, and Parkes, with no claim constructions proposed and the case at the petition stage. (Arctic Invent PTAB case database, https://cases.arcticinvent.com/us/patent/us/petition-as-filed/ipr2026-00310/; corroborated by Patsnap's litigation record for 1:25-cv-00408, which lists "IPR2026-00310 … filed by VideoAmp Inc" on the '402 patent.)

Two non-exclusive explanations: (a) the metadata mislabels the petitioner (plausible — portal.unifiedpatents.com is Unified's free PTAB database, not an indicator that Unified is a party, and its IPR2025-00556 page lists petitioner counsel as Fish & Richardson, not Unified); or (b) Unified Patents is a real party in interest behind a VideoAmp-named petition. I cannot resolve this from available sources, and per my operating rules I defer to the metadata for party names — but the contradiction should be flagged in the finished product, because it changes the "plaintiff's counsel" section already drafted (which builds on Unified Patents' in-house team: Stroud, Hughes, Rossen, Mansinghani, and Erise's Eric Buresh).

What does not change: Nielsen is the patent owner / respondent either way, so the defendant-side counsel analysis below stands.

Counsel of record for the patent owner (Nielsen)

Candid bottom line: I could not locate a docketed Power of Attorney, Mandatory Notice, or pro hac vice order naming counsel in IPR2026-00310 itself. No PACER/PTAB document for this specific proceeding surfaced in my searches — only third-party petition summaries, which do not list counsel. What follows is therefore (1) the counsel of record confirmed in Nielsen's closely related PTAB proceedings, which is a strong but not documentary basis for identifying counsel here, and (2) Nielsen's district-court and prosecution counsel, clearly separated.

A. Most likely PTAB counsel (identified from related Nielsen proceedings — not yet confirmed for this IPR)

Erise IP, P.A. is Nielsen's PTAB counsel of record in the VideoAmp/Nielsen dispute and in prior Nielsen IPRs.

Corroboration that Erise is Nielsen's standing PTAB counsel against VideoAmp: Unified Patents' PTAB database entry for IPR2025-00556 (VideoAmp Inc. v. The Nielsen Company US LLC) lists Patent Owner counsel as Erise IP, P.A. and Petitioner counsel as Fish & Richardson P.C. (https://portal.unifiedpatents.com/ptab/case/IPR2025-00556).

Relevant track record for these attorneys on the '402 patent family / same adversary: the Board's Jan. 6, 2025 Final Written Decision in IPR2023-01014 held all challenged claims of the '243 patent unpatentable, and the Federal Circuit affirmed on Aug. 14, 2026 in a precedential decision, The Nielsen Company (US), LLC v. TVision Insights, Inc. (IPWatchdog, Aug. 17, 2026). Separately, Nielsen's '402 patent claims were held invalid in Nielsen v. VideoAmp, 1:25-cv-00408 (D. Del.), where the R&R was adopted and the motion to dismiss granted (case closed Mar. 18, 2026) — which is almost certainly the discretionary-denial and § 101 backdrop for this petition.

B. Nielsen in-house personnel (identified as patent-owner representatives, not counsel of record)

At the IPR2023-01014 hearing, besides outside counsel, "representatives from the Patent Owner" present were Sal Karottki, Justin Cook, and Greg Huffman (IPR2023-01014 Doc. 33). They were not introduced as counsel arguing the case; I would not describe them as counsel of record or assign titles without a source.

C. Nielsen's district-court counsel (not PTAB counsel — do not conflate)

In Nielsen's patent assertions, the recurring plaintiff-side teams are:

• Kelley Drye & Warren LLP — Steven Yovits, Clifford E. Katz, Jason P. Greenhut, Constantine J. Koutsoubas, Malavika Rao, Mark J. Scott.
• Potter Anderson & Corroon LLP (Delaware local counsel) — David E. Moore, Bindu A. George Palapura, Brandon R. Harper.

These names appear as "attorneys of record for Plaintiff in the concurrent litigation matter" served with the IPR2023-01014 Power of Attorney, and recur in the D. Del. dockets (e.g., Nielsen v. Hyphametrics, Nielsen v. VideoAmp).

D. Prosecution / correspondence counsel (not litigation counsel)

Nielsen's USPTO correspondence address of record is Hanley, Flight & Zimmerman, LLC (Nielsen), 150 S. Wacker Dr., Suite 2200, Chicago, IL 60606, with patent owner address The Nielsen Company (US), LLC, 85 Broad Street, New York, NY 10004 (per the certificate of service in IPR2023-01014 Doc. 1, June 16, 2023). HFZ drafted/prosecuted the family and is a likely source of the § 103 and claim-construction positions, but would not normally appear as IPR counsel of record.

(For completeness, on the petitioner side of this IPR/related matters: Fish & Richardson P.C. appeared for VideoAmp in IPR2025-00556; the D. Del. defendant's attorneys in Nielsen v. VideoAmp were Charles N. Reese, Aamir A. Kazi, and Susan E. Morrison, consistent with Fish's Delaware presence.)

Sourcing caveats

• Confirmed by document: Erise IP (Bailey lead; Snader; Redmond PHV) as Nielsen's PTAB counsel in IPR2023-01014; Erise IP as Nielsen's patent-owner counsel in IPR2025-00556; HFZ as Nielsen's correspondence address; Kelley Drye/Potter Anderson as Nielsen's district-court counsel.
• Not confirmed / inference: that the same Erise team appears in IPR2026-00310. This is a well-supported inference from continuity across the VideoAmp dispute, but no power of attorney, mandatory notice, or PHV order for IPR2026-00310 was retrievable. Anyone filing on this should pull the PTAB docket directly via USPTO Patent Center / PTAB-E2E (IPR2026-00310) or call the Board's docketing line before relying on it.
• Timing note (inference, not sourced): if the petition was filed in spring 2026, the patent owner's preliminary response and any institution decision would fall in late 2026; docket entries reflecting counsel appearances may exist even though they were not indexed by the sources I could reach.
• I have not named any attorney, registration number, or filing date that I could not tie to a retrieved source.
