Valtrus Innovations Ltd. et al. v. Cogent Communications Holdings Inc.

I'll research this case across multiple sources.

Good foundation. Now let me drill into the MDL, the Cogent defendant, and the '277 patent's IPR/expiry status.

Case Overview — Valtrus Innovations Ltd. et al. v. Cogent Communications Holdings Inc.

The parties. Plaintiffs Valtrus Innovations Ltd. and Key Patent Innovations Ltd. ("KPI") are Dublin-based patent-holding companies — i.e., non-practicing assertion entities, not operating companies or universities. Valtrus is a wholly owned subsidiary of KPI that acquired a large tranche of Hewlett-Packard/HPE patents in May 2021 (assignments recorded at Reel/Frame 56157/0492 and 55269/0001), and it holds those patents in trust for KPI as beneficial owner; KPI's own upstream parent was disclosed in a related 2026 filing as New PP Licensing LLC. Valtrus's Managing Director is simultaneously KPI's Managing Director, and Valtrus has stated in PTAB papers that more than fifty entities have taken licenses to its portfolio without litigation. Defendant Cogent Communications Holdings, Inc. (Nasdaq: CCOI) is a publicly traded Tier-1 internet backbone/transit provider and data center operator; the caption's "et al." is confirmed by the E.D. Tex. docket to include Cogent Communications LLC, Cogent Fiber LLC, and Cogent Infrastructure LLC as co-defendants (PacerMonitor docket, 2:26-cv-00799). Notably, Valtrus and KPI — not Cogent — are the parties who moved the JPML to centralize this campaign in E.D. Texas (JPML July 30, 2026 hearing notice).

The patent and the accused technology. The case metadata lists a single asserted patent, U.S. Patent No. 6,718,277 (the "'277 patent"), which issued April 6, 2004 from an application filed in 2002 and is titled/directed to a method of controlling atmospheric conditions within a building (claim 1) and, more specifically, a method of cooling a data center (claim 12): supplying conditioned/cooling fluid; sensing temperature or other atmospheric parameters at a plurality of locations; generating an "empirical atmospheric [thermal] map"; comparing it against a "template atmospheric map"; and identifying "pattern differentials" — essentially sensor-based, map-driven data center cooling optimization (see the claim text reproduced in Valtrus's claim-construction/IPR papers). Valtrus's infringement theory across this campaign is aimed at end users, not equipment makers: it accuses data center operators of directly performing the claimed cooling methods using commercially available cooling equipment and controls from third-party suppliers — its sample claim chart for a co-defendant accuses use of Vigilent's AI-based airflow optimization and Vertiv/Liebert iCOM and iCOM-S cooling controls (same claim chart link) — which is why equipment vendors such as Vertiv intervened and filed declaratory-judgment and IPR challenges. Valtrus's parallel suits against other operators (e.g., Lumen, Compass Datacenters, Cologix, CoreSite, NTT, Iron Mountain, Prime, Markley, Sabey) also asserted companion data center cooling patents such as U.S. 6,854,287, 6,868,682, 6,868,683, 6,862,179 and 7,031,870, so the single-patent focus in the Cogent metadata may understate the complaint; I could not retrieve the Cogent complaint itself, so the specific accused cooling equipment at Cogent's sites and the exact count list are unverified.

Procedural posture, venue, and why it matters. The case began as N.D. Tex. (Dallas Division) No. 3:26-cv-02758, filed on or about August 18, 2026 and assigned to Judge Sam A. Lindsay with pretrial referral to Magistrate Judge David L. Horan; a Report to the Patent Office issued Aug. 20, 2026 (Docket 8), and Valtrus filed a Notice of Related Case (Docket 2) and a motion to proceed without local counsel (granted Aug. 27, 2026). The JPML's Conditional Transfer Order 2 in MDL No. 3190, In re Valtrus Innovations Ltd. Patent Litigation, was filed in the transferor court (Docket 11, dated Sept. 4, 2026) and the case was transferred in to the E.D. Tex. on September 9, 2026, renumbered 2:26-cv-00799 and assigned to Chief Judge Rodney Gilstrap, with all pending motions deemed moot and required to be re-urged under L.R. CV-7(j) (PacerMonitor docket). MDL 3190 itself was created after a motion by Valtrus and KPI; the Panel's August 7, 2026 order transferred seven actions to E.D. Tex. before Judge Gilstrap (CTO-1 text), and the JPML's Sept. 1, 2026 pending-docket list shows roughly a dozen actions in the MDL. Venue matters on two axes: (i) Gilstrap already presides over the earlier Valtrus data-center campaign (e.g., Valtrus v. NTT Data Services, 2:24-cv-00361) and runs one of the fastest large patent dockets in the country — Valtrus itself has cited a ~21.9-month median time-to-trial in E.D. Tex. in stay briefing — and (ii) consolidation resolves the plaintiffs' multi-district scatter (N.D. Tex., N.D. Ill., D.N.J., W.D. La., E.D. Cal., D. Mass.) into a single pretrial forum. Why the case is notable: it is the operator-targeting wing of a broad, well-financed NPE campaign that has already generated a dense web of IPRs, ex parte reexaminations, and supplier declaratory-judgment actions (Unified Patents has published a member analysis of the Valtrus program: Unified Patents insights); it sits atop the AI/cloud-driven data center buildout, where cooling is one of the largest cost and energy line items; and it carries a serious standing overlay — courts have repeatedly held that Valtrus, holding title but not "all substantial rights," lacked statutory standing under 35 U.S.C. § 281 (Valtrus v. SAP, E.D. Tex. Nov. 8, 2024), and the N.D. Cal. court dismissed the consolidated Valtrus v. Google cases outright, finding Valtrus lacked constitutional standing at filing (an incurable defect) and that the follow-on "Valtrus II" suit violated the rule against claim splitting (order, N.D. Cal. No. 25-cv-07063-PCP) — which is why KPI now appears as a co-plaintiff in the 2026 wave, including against Cogent. Finally, because Valtrus has conceded in briefing that the '277 (and '287) patent expired in 2022, recovery here is confined to past damages within the six-year lookback window, and the main invalidity vehicle is Vertiv's petition in IPR2025-00669 on the '277 patent (cited in the NTT case P.R. 4-3 statement); I could not confirm that IPR's institution outcome or any Cogent-specific IPR on the '277 patent, and no Cogent-side counsel appearances, motions to stay, or transfer briefing were found in the sources reviewed.

Unverified/uncertain: the Cogent complaint's specific counts, accused products and notice history; Cogent's defense counsel; whether the '277 patent is the sole asserted patent (metadata says yes, but Valtrus's other 2026 operator suits asserted three or more patents); and the disposition of IPR2025-00669.

I'll research this case across multiple sources. Let me start with parallel searches.

Let me dig into the Cogent-specific docket and the PTAB picture.

I'll research this case across court records, docket sources, and firm/industry coverage.

Good initial hits. Let me pull the specific dockets and filings for both case numbers.

Bottom line

The public docket for both the N.D. Tex. original and the E.D. Tex. MDL-transferred case shows exactly one attorney of record for the plaintiffs (Valtrus Innovations Ltd. and Key Patent Innovations Ltd.): Eric Hugh Findlay of Findlay Craft, P.C. (Tyler, Texas). No other attorney has entered an appearance on this docket, and no in-house counsel is listed for either plaintiff. The broader Valtrus data-center campaign is run by a Reichman Jorgensen Lehman & Feldberg LLP trial team, but I found no docket confirmation that any R.J. attorney has appeared in this Cogent case — treat that as a related-case inference, not a verified fact for this docket.

Counsel of record appearing on this docket

Everything he filed in the N.D. Tex. phase is attributed to him alone on the docket sheet:

• Dkt. 1 — COMPLAINT WITH JURY DEMAND against Cogent Communications Holdings, Inc., Cogent Communications LLC, Cogent Fiber LLC, Cogent Infrastructure LLC
• Dkt. 2 — NOTICE of Related Case (Findlay, Eric)
• Dkt. 3 — CERTIFICATE OF INTERESTED PERSONS / DISCLOSURE STATEMENT (Findlay, Eric); clerk QC note flags an "affiliate entry"
• Dkt. 4 — MOTION to Proceed Without Local Counsel (Findlay, Eric)
• Dkt. 5 — Request for Clerk to issue Summonses (Findlay, Eric)

---

Local-counsel posture (documented)

• On Aug. 27, 2026, Magistrate Judge David L. Horan granted plaintiffs' motion to proceed without local counsel (Dkt. 10), on referral from Judge Sam A. Lindsay (Standing Order of Reference, Dkt. 9, Aug. 21, 2026). That makes sense structurally: Findlay Craft's office is in Tyler, inside the Eastern District, and plaintiffs evidently intended from the outset to litigate in the Marshall/E.D. Tex. orbit.
• After transfer this is a live housekeeping item. The case transferred in on Sept. 9, 2026 via Conditional Transfer Order (CTO-2) in MDL No. 3190 (Dkt. 11), and E.D. Tex. Dkt. 12 expressly warns that under LR CV-7(j) any motion pending in the transferor district "is considered moot, has been terminated, and must be re-urged." So the N.D. Tex. local-counsel order is spent; the E.D. Tex. local-counsel requirement will be governed by that court's rules (satisfied by Findlay Craft's Tyler office, unless the court directs otherwise as part of MDL coordination).
• Case is assigned to Judge James Rodney Gilstrap (E.D. Tex., Marshall Division).

The wider Valtrus trial team (related cases — not verified on this docket)

Across the companion Valtrus matters that now sit inside the same MDL cluster, the substantive briefs are signed by a Reichman Jorgensen Lehman & Feldberg LLP team. Signature blocks I can source from related filings:

Sources: Valtrus Innovations Ltd. v. NTT Data Services, LLC, E.D. Tex. 2:24-cv-00361, Dkt. 151 (answer/counterclaim signature blocks listing Berkowitz, Morris, Colsher, Houghton, Mann and Findlay) and Dkt. 3 in the same family (Findlay signature block identifying Berkowitz as lead attorney); E.D. Tex. 4:25-cv-… / 2:24-cv-00021-JRG filings attributed to "Henry, Claire" for Key Patent Innovations Ltd. and Valtrus.

Two additional names surfaced in the SAP (E.D. Tex. 2:24-cv-00021-JRG) Valtrus litigation — Claire Henry (filing attorney for Valtrus/KPI, docket entries through 2025) and Rikesh Patel (Notice of Attorney Appearance for Valtrus/KPI, Jan. 21, 2025). I could not confirm either attorney's firm or whether they have any involvement in the Cogent matter; I am flagging them only as names on the Valtrus docket trail, not as counsel here.

Basis for the R.J. inference: R.J. maintains a shared case mailbox that appears in meet-and-confer correspondence for this campaign (RJ_ValtrusDataCenter@reichmanjorgensen.com), and R.J. attorneys are the primary signatories on Valtrus's substantive briefs in the MDL 3190 family. But for this docket, Findlay is the only appearance on file.

---

Caveats and things I could not verify

• No sealed appearance information is at issue. The docket through entry 12 is public; nothing suggests an attorney has been admitted or appeared under seal. The absence of R.J. attorneys is simply because no R.J. attorney has filed an entry of appearance in 3:26-cv-02758 / 2:26-cv-00799 yet, which is normal at the pleading-and-transfer stage — the complaint was filed in mid-August 2026 and the case was transferred three weeks later.
• The complaint's own signature block (Dkt. 1) was not reproduced in the sources I could retrieve; the CM/ECF filer tag on every N.D. Tex. filing is Findlay. If R.J. attorneys are listed on the complaint but never separately noticed their appearance, that would not show up in the "Represented By" field.
• MDL 3190 liaison counsel. The JPML docket for In re: Valtrus Innovations Ltd. Patent Litigation, MDL No. 3190 (filed April 28, 2026; 7 actions transferred to E.D. Tex. by the Aug. 7, 2026 order, CTO-1/CTO-2 tag-alongs assigned to Judge Gilstrap), lists generic "Liaison Counsel for Plaintiffs" / "Liaison Counsel for Defendants" placeholder entries. I could not retrieve the names, so I cannot say whether a plaintiffs' liaison counsel has been designated who would also speak for Valtrus here.
• No in-house counsel. Valtrus Innovations Ltd. and Key Patent Innovations Ltd. are Irish IP-holding entities (registered office: The Glasshouses GH2, 92 Georges Street Lower, Dun Laoghaire, Dublin, A96 VR66, Ireland). Their public filings identify no in-house litigation counsel; the trust structure (Valtrus holds the patents in trust for KPI) means KPI is a co-plaintiff, which is itself a litigation-driven joinder strategy following adverse § 281 "all substantial rights" rulings — see Valtrus Innovations Ltd. v. Google LLC, N.D. Cal. No. 5:25-cv-07063, order of March 16, 2026 (dismissing Valtrus I and II; discussing the Lone Star/Nanya standing rulings and the KPI joinder gambit).

Recommended next step for confirmation: pull the actual Dkt. 1 complaint PDF and any Notice of Attorney Appearance filed after the Sept. 9, 2026 transfer into E.D. Tex. (docket entries 13+), plus the MDL 3190 docket's liaison-counsel designations, before relying on any name beyond Eric H. Findlay.

I'll research the defendant's counsel across docket, firm, and news sources.

Let me verify the docket appearance history and look for Cogent's counsel in the related MDL/parallel cases.

Bottom line

No counsel of record for the Cogent defendants could be identified in this case. As of the most recent docket data I could retrieve (a PacerMonitor snapshot of E.D. Tex. 2:26-cv-00799 "last updated" the same day I searched), the only attorneys listed as appearing are for the plaintiffs. Every "Represented By" entry on the docket belongs to Valtrus Innovations Ltd. / Key Patent Innovations, Ltd. No notice of appearance, corporate disclosure, answer, or motion has been filed on behalf of Cogent Communications Holdings, Inc., Cogent Communications LLC, Cogent Fiber LLC, or Cogent Infrastructure LLC. I did not find any firm website, Law360/Reuters item, PTAB paper, or court opinion naming Cogent's counsel in this action.

What the docket actually shows (docket entries as retrieved)

Note the ordering: ECF 1–12 are the N.D. Tex. file; the E.D. Tex. docket picks up post-transfer. Nothing after the transfer agent entry reflects a defense appearance.

Plaintiffs' side (for context only): Eric Hugh Findlay, Findlay Craft, P.C. (Tyler, TX) — a well-known E.D. Tex. patent litigator and former federal clerk/longtime local counsel in Marshall/Tyler patent dockets. Valtrus/KPI are also represented by Connor Houghton and Matthew G. Berkowitz of Reichman Jorgensen Lehman & Feldberg LLP (appearing for plaintiffs in the parallel Massachusetts tag-along, Valtrus Innovations Ltd. v. Markley Network Services, 1:26-cv-13811, and in the E.D. Tex. Valtrus matters). I did not confirm a Reichman Jorgensen appearance in this Cogent file.

Why there is no defense counsel yet (procedural reality, not a sealed filing)

• The complaint was filed 8/18/2026 and the case was transferred to the MDL on 9/9/2026 — nine days before today. Even with prompt service, the Rule 12(a)(1)(A) response clock and the practical need to select counsel mean an appearance is only now becoming due.
• Under E.D. Tex. L.R. CV-7(j), upon transfer "any motion pending in the transferor district is considered moot, has been terminated, and must be re-urged" (Docket 12). That resets defense-side motion practice and is another reason appearances are lagging.
• Because the JPML's CTO-2 was transferred with the consent of the E.D. Tex. court and assigned to Judge Gilstrap, the defendants will appear in the 2:26-cv-00799 (Marshall Division) file, not the N.D. Tex. one. Anyone monitoring the old 3:26-cv-02758 docket will see nothing.
• I found no indication of a sealed appearance. A sealed notice of appearance is essentially unheard of; the absence is almost certainly a matter of timing.

Adjacent-record facts about Cogent that are well sourced (and their limits)

• Cogent Communications Holdings, Inc. already has a footprint in the Valtrus campaign. It is named as a counterclaim-defendant in Valtrus/KPI's counterclaim in the related E.D. Tex. case Valtrus Innovations Ltd. v. NTT Data Services, LLC, No. 2:24-cv-00361 (the Vertiv declaratory-judgment action and one of the MDL 3190 constituent cases). Dkt. 151 in that case identifies Cogent as a Delaware corporation serviceable at Corporation Service Company, 251 Little Falls Drive, Wilmington, DE 19808. That is Cogent's registered agent — useful if you need to confirm service, but it is not a counsel identification.
  • https://storage.courtlistener.com/recap/gov.uscourts.txed.[230090](/patent/230090)/gov.uscourts.txed.230090.151.0.pdf
• The MDL 3190 docket is the best place to spot Cogent's counsel early. Some similarly situated data-center defendants have appeared through Timothy P. Maloney, who filed on behalf of STACK Infrastructure, Cologix, CoreSite, NTT Global Data Centers Americas, H5 Data Centers, Netrality, Prime Data Centers, Iron Mountain, Lumen, EvoDC and Vertiv in the JPML/MDL filings (see the D. Mass. tag-along docket, Valtrus Innovations Ltd. v. Markley Network Services, 1:26-cv-13811 docket sheet, MDL 3190 associated-case entries dated May 2026). Because Cogent is defending the same Vertiv-supplied data-center-cooling technology, it is plausible Cogent joins a common defense group — but I found no filing that establishes Maloney, or any firm, as Cogent's counsel, so treat that as a hypothesis only.
• Do not confuse this with the separately appearing defendants. In the consolidated Vertiv action, counsel appearing for other parties include Melissa Richards Smith (Gillam & Smith LLP, Marshall) for CyrusOne; Gregory S. Arovas and Sean M. McEldowney (appearing pro hac vice, Kirkland & Ellis) in the same CyrusOne filing; and Holly Elin Engelmann and Louis Norwood Jameson for T5 Data Centers. These are sourced appearances for defendants other than Cogent and should not be attributed to Cogent.

Flags on the case metadata

1. Patent number. Your metadata lists "6718277." The Valtrus data-center-cooling portfolio asserted in the parallel cases includes U.S. Patent No. 6,718,277 (the "'277 patent"), which is the patent CyrusOne, Valtrus, and Vertiv litigate in 2:24-cv-00361. The metadata figure is almost certainly a formatting truncation of 6,718,277, but I could not open the ECF No. 1 complaint itself to confirm the patent(s) charted against Cogent, so I'd verify against the complaint before relying on it.
2. Caption. The metadata's "et al." resolves to three additional Cogent entities — Cogent Communications LLC, Cogent Fiber LLC, and Cogent Infrastructure LLC (ECF 7) — consistent with the note in the existing summary.

Recommended verification steps (which I could not complete within search limits)

1. Pull the live E.D. Tex. 2:26-cv-00799 docket on PACER and filter for "Attorney Appearance," "Corporate Disclosure Statement," and "Answer" — check filters from 9/9/2026 forward.
2. Check the MDL 3190 JPML/transferee dockets for a defense liaison or steering-committee order, which typically names counsel for clusters of similarly situated defendants.
3. If Cogent was served through CSC in Wilmington, defense counsel selection will likely show up alongside a motion to extend the responsive deadline — usually the first defense filing and a reliable signal.
4. Any counsel who enters will need to re-urge or refile under L.R. CV-7(j); the first defense-side filing in the E.D. Tex. file is the reliable proxy for "counsel of record."

Bottom line for your deliverable: state affirmatively that no defense counsel has appeared as of September 18, 2026, and that the only confirmed attorney of record in the case is plaintiffs' counsel Eric Hugh Findlay (Findlay Craft, P.C.). Do not populate a defendant counsel table with names from the sibling Valtrus/Vertiv matters.
