IoT Innovations LLC v. Chamberlain Group LLC

Case Overview & Background

Parties. Plaintiff IoT Innovations LLC is a Texas-domiciled non-practicing entity affiliated with monetization firm Empire IP LLC (founded by New York attorneys Daniel Mitry and Timothy Salmon; IoT Innovations was created July 18, 2020). Public record shows IoT Innovations acquired a 30+ patent portfolio from Intellectual Ventures LLC (IV) via four July 2022 assignments—patents originally developed at Nokia, AT&T, and others—and has since filed roughly 30 suits, concentrated in the Eastern District of Texas, against makers of smart-home, security, and networking gear (TP-Link, Resideo/Snap One, Fibar, Nice, ecobee, Signify, Brinks Home/BH Security, D-Link, Lutron, Savant) (RPX; Unified Patents, May 16, 2025; RPX/Mondaq coverage of Empire IP campaigns). Defendant Chamberlain Group LLC is the Oak Brook, Illinois-based garage-door and smart-access company—known for its myQ connected garage-door openers and mobile app—and is an experienced patent litigant itself, having won a willful-infringement jury verdict in N.D. Ill. against Techtronic Industries (2017) and having been a respondent in a § 337 ITC investigation involving movable-barrier operator patents (Federal Register, Feb. 15, 2022; Fish & Richardson). Per PACER Monitor, IoT Innovations filed the complaint on Sept. 2, 2026 through Andrew Gordon-Seifert, with a jury demand and exhibits styled as evidence-of-use submissions; the case metadata lists U.S. Patent No. 7,161,960 as the patent at issue, although the complaint as docketed attached Exhibits A–F referencing six patents (7,161,960; 7,209,876; 7,246,173; 7,280,830; 9,008,055; RE44,742), so the precise asserted-patent set may still be confirmed as the case develops.

Patent, accused technology, and posture. The '960 patent, "Apparatus, and associated method, for forming, and operating upon, multiple-checksum-protected data packet," issued January 9, 2007 to Nokia Corporation (inventors Keith Miller and Marta Karzewicz); technically, it claims systems/methods for formatting packetized data (e.g., an extended UDP-Lite scheme) so that multiple, dynamically selectable portions of a packet are each protected by separately specified checksums identified in the packet itself (FreePatentsOnline). The companion patents in the docketed exhibits likewise trace to the IV-acquired networking portfolio (e.g., '876 covers natural-language querying of an information repository; '173 covers QoS for packet streams). The complaint's specifics as to the accused instrumentalities were not yet publicly summarized at the time of research (the case is two days old); consistent with this campaign's pattern, the accusation presumably targets Chamberlain's networked smart-access products—myQ-enabled openers, bridges, cameras, and related app/cloud services—but that characterization should be treated as inference, not confirmed allegation. Procedurally, the case is in the U.S. District Court for the Northern District of Illinois (Case 1:26-cv-10653), Eastern Division docket, nature of suit 830 (Patent); no judge assignment, answer, or scheduling order is yet reflected in public sources, and IoT Innovations has filed the Local Rule 3.2 affiliate notification and 3.4 patent-claims notice. Venue is significant because Chamberlain's Oak Brook headquarters lies within the district, making N.D. Ill. a home-venue forum under § 1400(b)/TC Heartland—a notable departure from IoT Innovations' usual E.D. Tex. venue and one that eliminates the standard venue-transfer fight.

Why it matters. This appears to be IoT Innovations' first N.D. Ill. filing in a campaign that defendants (e.g., Lutron) have publicly attacked as serial assertion of expired or near-expired legacy Nokia/AT&T patents against IoT companies, using litigation cost to force settlements—allegations IoT Innovations denies, touting the patents' Nokia/AT&T lineage. The case also puts a network-protocol patent (multi-checksum UDP-style packet formation) against a defendant whose connected garage-door ecosystem depends on Wi-Fi/app communications, raising both § 101 eligibility and claim-construction exposure. Chamberlain is a sophisticated counter-party—it has litigated its own GDO connectivity patents in N.D. Ill. and before the Federal Circuit (Chamberlain Group v. Techtronic, where the Federal Circuit applied Alice to invalidate a rival's wireless-GDO patent while affirming Chamberlain's battery-patent verdict)—so the docket may see early § 101 and/or Rule 11-style pushback. Finally, the case is on Unified Patents/RPX radar given prior ex parte reexamination against a different IoT Innovations patent (8,085,796, challenged May 2025), signaling possible validity challenges to this portfolio as well. (Note: no judge, defense counsel, or substantive rulings are yet on the public docket; statements about the accused products are inferences from the campaign pattern, not confirmed complaint allegations.)

I'll research the current docket and any related proceedings before writing.

Key Legal Developments & Current Posture

Bottom line: This case is nine days old. As of 2026-09-11 the public record contains only two confirmed docket facts — the complaint and the judge assignment. There is no answer, no motion, no scheduling order, no claim construction, no PTAB proceeding on the asserted patent that I could locate, and therefore no outcome. Anything beyond that is a forward-looking procedural roadmap, which I've labeled as such rather than presenting it as docket fact.

I. Confirmed developments (chronological)

That is the entire substantive docket. Note a metadata discrepancy: the third-party aggregator page (ai-lab.exparte.com/case/dct/ilnd/1:26-cv-10653/...) still displays "Pending Judge Assignment," while the court's own recently-filed-case listing shows Judge Alonso as of 2026-09-03 — the court list is the more reliable source. Separately, as flagged in the prior section, the case metadata names only U.S. Pat. No. 7,161,960 while the docketed exhibits referenced six patents (7,161,960; 7,209,876; 7,246,173; 7,280,830; 9,008,055; RE44,742). I could not confirm whether the operative complaint as amended asserts one patent or six; that materially affects every downstream development (joinder, severance, multiple IPR petitions, § 101 motion practice).

II. Filing & initial pleadings — what exists, what is expected

Confirmed: complaint only.

Not yet on the docket (as of research): answer, Rule 12 motion, counterclaims (Chamberlain is a frequent counterclaimant and a plaintiff in its own right — e.g., its N.D. Ill. and ITC actions against competitors over GDO/movable-barrier patents), Rule 7.1 disclosure, and any Local Patent Rule filings beyond the LPR 3.2 affiliate notification and LPR 3.4 patent-claims notice described in the prior summary.

Expected timing (inference, not fact): Chamberlain's response is due 21 days after service (Fed. R. Civ. P. 12(a)(1)(A)(i)) or 60 days if it waives formal service under Rule 4(d) — i.e., roughly late September through mid-November 2026. Given Chamberlain's sophistication and history of § 101 litigation (see the Federal Circuit's Chamberlain Group v. Techtronic line discussed in the prior section), a Rule 12(b)(6) eligibility challenge and/or counterclaims are plausible, not confirmed.

III. Pre-trial motions of substance

None filed. Forthcoming phases to watch, with the specific hooks that matter here:

1. Venue — Unlike IoT Innovations' E.D. Tex. campaign (where it consolidates cases, e.g., IoT Innovations v. D-Link, No. 2:25-cv-01009, consolidated into lead case 2:25-cv-1135 by order of 2026-02-23), venue is not genuinely contestable here: Chamberlain's Oak Brook, Illinois headquarters sits in this district, so § 1400(b)/TC Heartland is satisfied. No transfer fight expected. (dockets.justia.com docket for 2:25-cv-01009.)
2. Motion to dismiss under § 101 — the highest-probability early substantive motion, both because the '960 claims (packet formatting with multiple, dynamically selectable checksums identified in the packet) are computer-implemented, and because Chamberlain's counsel pool has litigated Alice extensively. Unverified.
3. Motion to stay pending PTAB review — only if Chamberlain files an IPR/PGR first (see § VII).
4. Partial stay/severance — IoT Innovations has itself moved to sever and stay counts in its other cases (in D-Link, an unopposed motion to sever and stay Count VII, granted 2026-01-16 and entered 2026-01-21), a pattern that tends to appear when one asserted patent is in reexam. A similar mechanism could be used here to carve out any patent under PTAB attack.
5. Summary judgment — no earlier than 2027 under any realistic N.D. Ill. schedule.

IV. Claim construction

Not reached. No Markman order, no joint claim construction statement, no Phillips briefing. N.D. Ill. Local Patent Rules would normally set infringement contentions, invalidity contentions, and a claim-construction exchange, with a Markman hearing typically 9–15 months post-filing in a normal patent case (which would put it in mid-to-late 2027). The '960 claim terms most likely to be disputed are the multi-checksum selection mechanism and the claim-embedded checksum-identifier limitations — but no contentions exist to test that. The single most useful leading indicator of claim-construction risk is the parallel Federal Circuit appeal in the Lutron case (below), which may produce a written ruling on IoT Innovations' claim scope in a related portfolio patent.

V. Discovery milestones

No discovery has occurred; no Rule 26(f) conference or scheduling order is on the docket. Expect: initial disclosures, a N.D. Ill. discovery schedule, and — given the campaign pattern — early focus on damages apportionment (NPE portfolio acquired from Intellectual Ventures; the '960 patent traces to Nokia, with named inventors Keith Miller and Marta Karzewicz). A threshold issue that likely gets litigated at the pleading/damages stage: the remaining patent term and the § 286 six-year damages look-back. The '960 patent issued 2007-01-09; if its 20-year term (plus any PTA) has run, no post-expiration damages accrue and only pre-expiration sales within the statutory window are recoverable. I was not able to verify the '960 patent's expiration date or any PTA from the sources retrieved — this should be checked in the USPTO file wrapper before it's treated as an issue. The prior section notes defendants in this campaign (Lutron) have publicly attacked it for asserting "expired or near-expired" patents.

VI. Trial, verdict, post-trial, final disposition

None — and none possible yet. The present posture is "open, early pleading stage." No trial date, no verdict, no JMOL/Rule 59/Rule 54(d) motion, no settlement, no judgment, no appeal in this case. Realistically a 2026-filed N.D. Ill. patent case would not reach trial before 2028 or later absent early dispositive resolution.

VII. Parallel PTAB / USPTO proceedings on the asserted patents

• No IPR, PGR, or CBM proceeding on U.S. Pat. No. 7,161,960 was located. My PTAB-directed search for "7,161,960" returned no results; I cannot conclusively rule out a recently filed petition that hasn't yet appeared in indexed sources, and I found no ex parte reexam against '960 either. Treat "no challenge identified" as the state of the record, not as proof of none.
• What does exist in the family of campaign proceedings: Unified Patents filed an ex parte reexamination against U.S. Pat. No. 8,085,796 (a different IoT Innovations patent, directed to controlling communications with user communication devices) on 2025-05-16, and the Central Reexamination Unit granted the request on 2025-06-05, finding substantial new questions of patentability. Unified is represented in-house by Michelle Aspen and Kelly Hughes. (unifiedpatents.com/insights, Reexamination category; reexam control no. 90/019,965.) The '796 patent is not among the patents named in this case's docketed exhibits.
• Effect on this litigation: none yet, directly. The indirect effects are (a) proof that this portfolio draws Unified/RPX scrutiny, making a Chamberlain- or Unified-funded PTAB or reexam challenge to '960 a realistic mid-term development; and (b) a § 315(b) clock — if Chamberlain is served with the complaint, any IPR petition must be filed within one year of service, i.e. roughly by September 2027 if service occurred promptly. A stay motion would typically follow an instituted IPR.

VIII. Related/parallel litigation as the real "developments" to track

Because this docket is empty, the substantive legal events in this campaign are happening elsewhere and are the best available predictors:

1. IoT Innovations LLC v. Lutron Electronics Co., Inc., Fed. Cir. No. 26-1297 — appeal docketed 2025-12-31 (notice received 2025-12-24). Appellant IoT Innovations is represented by Jonathan L. Hardt and James F. McDonough, III; appellee Lutron by Fred A. Rowley, Jr. (principal), James C. Yoon, Matthew Macdonald, John B. Kenney, Neil N. Desai, and Ian F. Sprague. IoT Innovations' opening brief was extended to 2026-04-16 by a text-only order entered 2026-02-20. The appeal appears to arise from the S.D. Fla. case IoT Innovations v. Lutron Electronics, No. 0:25-cv-60483 (a case in which IoT Innovations asserted, among others, the '173, '266, '260, '872, '571, and RE44,742 patents — overlapping the RE44,742 reference in this case's exhibits). The docket does not disclose which underlying order is on appeal or its substance, and I could not verify any Federal Circuit decision. If the appealed ruling is an invalidity or claim-construction judgment adverse to IoT Innovations, it is the most consequential development for evaluating Chamberlain's exposure. Source: dockets.justia.com/docket/circuit-courts/cafc/26-1297.
2. E.D. Tex. campaign consolidation — IoT Innovations v. D-Link, No. 2:25-cv-01009 (filed 2025-10-03), consolidated for all pretrial issues into lead case No. 2:25-cv-1135 by order of 2026-02-23 (Magistrate Judge Roy S. Payne); D-Link's answer deadline was extended to 2026-03-09 via a 2025-12-09 waiver of service. This shows the campaign's administrative momentum but no merits rulings.
3. Newest campaign filing before this one — IoT Innovations v. Signify Netherlands B.V., E.D. Tex. No. 2:26-cv-00736, filed 2026-08-23, asserting sixteen claims across the '876, '830, and other patents against Hue/WiZ ecosystems. It confirms the '876 and '830 patents from this case's exhibit list are being actively asserted elsewhere — relevant if Chamberlain moves to sever or if any of those patents are the real target here.

IX. Caveats and contradictions to flag

• Patent set contradiction (unresolved): case metadata says the '960 patent; docketed exhibits referenced six patents. My searches surfaced nothing resolving this.
• Judge assignment inconsistency: aggregator says "pending assignment," court's own list says Judge Alonso as of 2026-09-03. I defer to the court list.
• No substantive rulings found anywhere for this case, and no counsel identified for Chamberlain. I did not fabricate any.
• The '960 patent's expiration/PTA status is unverified and is potentially case-dispositive on damages.
• The "accused products" characterization remains inference, per the prior section — it is not a confirmed complaint allegation in the sources I retrieved.

I'll research the docket and counsel for this case.

Let me dig into the docket page and plaintiff's counsel.

Let me check the docket sheet source and possible local counsel.

Counsel of Record — Plaintiff IoT Innovations LLC

Status caveat up front: This case is nine days old (filed Sept. 2, 2026), and the docket is still in its earliest phase. I was able to confirm the filing attorney tied to the complaint, but I could not retrieve a complete PACER docket sheet or a full list of Rule 83.5 appearances, and no substantive filings or defense appearances are yet reflected in the public sources I could reach. Everything below is limited to what is sourced; where the record is thin, I say so rather than fill the gap.

Confirmed

This is consistent with — and confirms — the prior section's note (sourced to PACER Monitor) that "IoT Innovations filed the complaint on Sept. 2, 2026 through Andrew Gordon-Seifert," with a jury demand and evidence-of-use exhibits. His N.D. Ill. bar admission and Chicago presence explain his selection for this home-venue filing.

Not confirmed / not yet on the record

• Additional plaintiff-side attorneys (e.g., other Rozier Hardt McDonough lawyers, or Empire IP-affiliated counsel): I could not verify any beyond Gordon-Seifert. Additional appearances commonly follow within days of filing under Local Rule 83.5, so this list is very likely incomplete but I will not name anyone I cannot source.
• Local counsel: N.D. Ill. does not require separate local counsel if the filing attorney is admitted here, and Gordon-Seifert is admitted in this district, so a dedicated "local counsel" designation may not exist. Not confirmed either way.
• In-house counsel: None indicated; IoT Innovations is an NPE with no in-house litigation team of record.
• Defendant's counsel: Do not conflate with plaintiff's side. Chamberlain's historical N.D. Ill. patent counsel of record has been Fish & Richardson and Winston & Strawn (Kathi Vidal, Michael Rueckheim, Matt McCullough, Ben Elacqua, Maria Elena Stiteler) in Chamberlain Group v. Techtronic, 1:16-cv-06094/06097 — but no defense appearance in this case is confirmed in my sources. (Fish & Richardson; CourtListener #783)

Flags / corrections to the earlier section

1. Judge assignment now exists. The earlier section stated "no judge assignment … is yet reflected in public sources." The N.D. Ill. recently-filed-cases listing now shows Judge Jorge Alonso assigned to IoT Innovations LLC v. Chamberlain Group LLC (No. 26-cv-10653). (N.D. Ill. recently filed cases) This is a newer data point and supersedes that line.
2. Minor filing-date discrepancy: the N.D. Ill. listing shows a filed date of 09/03/2026, while the docket aggregator shows 09/02/26. The case metadata uses 2026-09-02; the one-day variance is likely a docketing/entry date, but I flag it.
3. Venue/§ 1400(b) point in the earlier section stands and is reinforced by the counsel profile: plaintiff's chosen attorney is N.D. Ill.–admitted, consistent with a deliberate home-venue strategy rather than the E.D. Tex. default.

What I could not do

I was unable to load the full PACER/CourtListener docket sheet for 1:26-cv-10653 or the firm's case-specific appearance filings (paywalled/registration-gated, and the docket aggregator page listed an "Attorney" field without exposing names in retrievable form). No appearance by any attorney other than Gordon-Seifert is verified. Anyone else representing IoT Innovations should be treated as unconfirmed until docket entries appear.

I'll research the docket and counsel appearances for this case. Let me run several searches.

Judge assignment appears now (Judge Jorge Alonso). Let me dig for the docket and any counsel appearances.

Let me search specifically for appearances in this docket and any matching entries on PACER aggregators.

Counsel of Record — Defendant Chamberlain Group LLC

IoT Innovations LLC v. Chamberlain Group LLC, No. 1:26-cv-10653 (N.D. Ill.)

Bottom line: no confirmed appearances yet on the public record

As of my research (Sept. 11, 2026 — nine days after the Sept. 2, 2026 filing), I could not confirm any attorney appearance, notice of appearance, or retained-counsel filing for Chamberlain Group LLC in this docket. Public aggregators reflect the case's existence but no defense-side counsel entries:

• The N.D. Ill. "Recently Filed Cases" list confirms the case and now shows Judge Jorge Alonso assigned as of 09/03/2026 (Case No. 26-cv-10653, "IoT Innovations LLC vs Chamberlain Group LLC"). Source: N.D. Ill. recently-filed cases page.
• The third-party docket mirror (Ex Parte / AI Lab) lists the case as "Pending Judge Assignment" with the plaintiff (patent owner) side populated but no defendant counsel listed. Source: ai-lab.exparte.com case page.

I am not going to name specific attorneys as "counsel of record" in this case, because I have no docket entry (e.g., a Notice of Appearance under Dkt. ##) grounding that claim. Chamberlain's appearance may simply not yet be filed — defendants typically answer within 21 days of service, so appearances would be expected in the coming weeks.

Two flags versus the earlier sections: (1) The prior Case Overview said "no judge assignment… is yet reflected" — that is now outdated; Judge Jorge Alonso is assigned per the court's own list. (2) Neither the court list nor the docket mirror shows the six-patent Exhibit set described earlier; the metadata and docket mirror both reflect only U.S. Patent No. 7,161,960, so the asserted-patent set remains unconfirmed.

Attorneys who do represent Chamberlain (context, not confirmed appearances here)

Chamberlain Group is a repeat patent litigant with a well-documented outside-counsel bench. The following firms/attorneys are publicly identified as Chamberlain's patent litigation counsel in other matters — useful for predicting who will likely appear, but not verified as appearing in 1:26-cv-10653:

Sources: Fish & Richardson — Benjamin C. Elacqua bio; Fish & Richardson press release, Sept. 7, 2017; Avantech Law — Kate Quisenberry bio.

In-house

Historically, Susan Bell served as General Counsel of The Chamberlain Group, described as guiding Chamberlain's litigation strategy "from beginning to end" in the TTI matter (Fish press release, 2017). I have no confirmation that Bell remains GC in 2026, so treat current in-house counsel as unverified.

What is not established

• No named lead counsel, local counsel, or of-counsel attorney confirmed for this docket.
• No firm press release, Law360/Reuters Legal report, or court opinion tied to 1:26-cv-10653 counsel was found.
• Whether the defense is being handled by Fish & Richardson (as in the Overhead Door and TTI defense/side matters) or another firm — e.g., Portus Singapore/Pty v. Chamberlain Group, filed April 2026 in D. Ariz. (4:26-cv-00296) and D. Utah (2:26-cv-00523), which are parallel Chamberlain patent defenses where the retained defense firm may be disclosed — is inference only.

Recommended verification steps

1. Pull the PACER docket for 1:26-cv-10653 and look for entries after Dkt. 1 (Complaint) — specifically Notices of Appearance, LR 83.15 local-counsel designations, and an Answer/Responsive Pleading (due ~21 days after service).
2. Cross-check the Portus v. Chamberlain dockets (D. Ariz. 4:26-cv-00296; D. Utah 2:26-cv-00523) — the defense firm appearing there is a strong signal for this case.
3. Watch firm newsrooms (Fish & Richardson, Winston & Strawn, Avantech) for a Chamberlain retention announcement.

If you can share a PACER docket sheet or the appearance entries, I can identify each attorney's name, role, firm, office, and litigation history precisely.
