US Patent 8,754,780 — Analyst Summary

1. Bibliographic data

Assignment chain (recorded June 9, 2014): Huff & Petite → Statsignal Systems, Inc. → Hunt Technologies, Inc. → SIPCO, LLC. There is a minor inconsistency in the record: the Google Patents page lists "Original Assignee: Sipco LLC," while the assignment reel shows the inventors assigned first to Statsignal. Later records show a 2019 security interest to Robbins Geller Rudman & Dowd LLP released back to SIPCO in 2020.

Priority chain as claimed in the '780 specification: continuation of 13/173,499 (filed Jun. 30, 2011, "Automotive Diagnostic Data Monitoring Systems and Methods") ← 12/477,329 (Jun. 3, 2009, issued as US 8,013,732) ← 12/337,739 (Dec. 18, 2008, US 7,978,059) ← 11/395,685 (Mar. 31, 2006, US 7,468,661) ← 10/139,492 (May 6, 2002, US 7,053,767) ← 09/439,059 (Nov. 12, 1999, US 6,437,692) ← CIP branches to 09/271,517, 09/102,178, 09/412,895, 09/172,554, plus provisional 60/146,817 (Aug. 2, 1999).

2. Abstract (verbatim, as published)

"Embodiments of the present invention are generally directed to a system for monitoring a variety of environmental and/or other conditions within a defined remotely located region. Such a system may be configured to monitor utility meters in a defined area. The system is implemented by using a plurality of wireless transmitters, wherein each wireless transmitter is integrated into a sensor adapted to monitor a particular data input. The system also includes a plurality of transceivers that are dispersed throughout the region at defined locations. The system uses a local gateway to translate and transfer information from the transmitters to a dedicated computer on a network. The dedicated computer, collects, compiles, and stores the data for retrieval upon client demand across the network. The computer further includes means for evaluating the received information and identifying an appropriate control signal, the system further including means for applying the control signal at a designated actuator. Other aspects, features, and embodiments are also claimed and described."

Plain language: a low-cost, wireless, ad-hoc "sensor/actuator → repeater transceiver → local gateway → Internet/WAN server" architecture. The central insight sold by the specification is that a general-purpose server on a WAN replaces the application-specific local controller of FIG. 1 (prior art), and that the transceivers are cheap, low-power, and largely identical, with location/purpose determined by lookup tables at the gateway/server rather than by hardware.

3. Independent claims — plain-language overview

The patent has two independent claims, 1 and 9, of a total claim set of 15 (claims 1–15 were the claims at issue in IPR2016-00984). Both independents are written as device/apparatus claims aimed at a node in the network rather than at the overall system.

Claim 1 (independent) — "In a system comprising a plurality of wireless devices, a device comprising:"

1. A transceiver with a unique identification code, electrically interfaced with a sensor, configured to receive select information plus identification information sent from a second (nearby) wireless transceiver in a predetermined signal type;
2. The same transceiver further configured to wirelessly retransmit — in that same predetermined signal type — (a) the select information, (b) the identification information of the second transceiver, and (c) its own transceiver identification information; and
3. A controller operatively coupled to the transceiver and sensor, controlling the transceiver, receiving sensor data, and formatting a data packet for transmission that contains data representative of the sensed data.

In plain terms: a self-identifying sensor node that both (i) acts as a repeater that appends its own ID when it forwards a neighbor's message, and (ii) originates its own sensor data packets. The "append your own ID when relaying" limitation is the core of the claim.

Claim 9 (independent) — "For use in a system including wireless devices, a thermostat device comprising:"
Substantively the same transceiver/receive/retransmit/append-own-ID architecture as claim 1, but the node is specifically a thermostat device — a wireless transceiver with a unique ID interfaced with a sensor, retransmitting a neighbor's message plus its own ID, and a controller that formats data packets containing sensed data.

Dependent claims (brief): control signals → actuator implementation (2, 7, 14); device type recited as thermostat / wearable / in-vehicle / utility meter / rain gauge / mobile inventory unit / irrigation control (3); function-code receipt and implementation (4); function code + unique ID in the outgoing packet (5, 13); memory storing function codes (6); electrically programmable unique ID (11); network-coupled user device providing user control signals for temperature control (12); second transceiver is "nearby" (8, 15).

4. Enforcement / validity history (relevant to "dockets")

I searched for CAFC activity tied specifically to 8754780. Findings and caveats:

• E.D. Tex. 6:15-cv-00907, Sipco, LLC et al. v. Emerson Electric Co. et al — the '780 was among the asserted patents in SIPCO's 2015–2016 campaign (also N.D. Ga. 1:15-cv-00319 and 1:16-cv-02690; and a Section 337 ITC action).
• IPR2016-00984, Emerson Electric Co. v. SIPCO, LLC — an inter partes review of US 8,754,780, petitioner Emerson, filed Apr. 29, 2016, instituted Nov. 2, 2016, before APJs Zado, Pettigrew and White. Reported outcome: all challenged claims (1–15) held unpatentable, with a final written decision reported by RPX as dated Jan. 24, 2020 (an earlier FWD is reported as Oct. 25, 2017).
• Federal Circuit Appeal No. 2018-1364, SIPCO, LLC v. Emerson Electric Co. — affirmed without opinion (Fed. Cir. R. 36), per curiam (Prost, C.J., Mayer and Moore, JJ.), January 21, 2021. Related SIPCO/Emerson appellate decisions appear at 939 F.3d 1301 (Fed. Cir. 2019) and 980 F.3d 865 (Fed. Cir. 2020).

On the specific request for "CAFC 2026 dockets": my searches returned no 2026 Court of Appeals for the Federal Circuit docket involving US 8,754,780. The only CAFC docket I can tie to this patent is 2018-1364 (disposed of in January 2021). This is consistent with the patent having reached its anticipated expiration on June 22, 2018 and being recorded as Expired – Fee Related. I do not have authoritative confirmation of there being zero 2026 activity — only that none surfaced in my searches; treat the negative as a search result, not a guarantee.

5. Explicit uncertainties

• Claim numbering/count. I report two independents (1 and 9) and 15 total claims, sourced from the published claim listing (Justia) and corroborated by the IPR2016-00984 petition challenging claims 1–15. One aggregator page displayed an incongruous "28/33 Claims" string next to this patent's image set; I could not reconcile that, so treat the 15-claim figure as high-confidence but not verified against the printed patent.
• Assignee of record. The reel shows Statsignal → Hunt → SIPCO; aggregators name SIPCO as "original assignee." I have not reconciled this.
• Exact PTAB procedural path. Two different FWD dates (Oct. 25, 2017 and Jan. 24, 2020) are reported by different litigation-data vendors, which may reflect a remand/re-issuance of the decision. I have not verified the docket to resolve this.
• The abstract's "means for evaluating … means for applying the control signal at a designated actuator" language does not appear in claims 1 or 9 as published; it appears to be descriptive abstract text rather than claim language. Do not assume the issued claims use means-plus-function recitations based on the abstract alone.

I'll search the litigation databases and dockets for US 8,754,780. Let me run several targeted queries in parallel.

Let me pull case-specific details on the dockets identified and check for any additional proceedings.

Bottom line

Searches for US 8,754,780 return two federal district court cases, one PTAB inter partes review, and one Federal Circuit appeal. All involve SIPCO, LLC (and affiliate IP CO, LLC) against Emerson Electric Co. and related entities/BP entities. I found no litigation filed in 2026 and no new dockets beyond those below. Note the patent's own record shows anticipated expiration June 22, 2018 and status Expired – Fee Related, and every challenged claim was held unpatentable in IPR2016-00984 — so the practical enforcement life of this patent appears to be over.

2. Case detail

E.D. Tex. 6:15-cv-00907 — the principal enforcement case.
Plaintiffs: SIPCO, LLC and IP CO, LLC. Defendants named in the docket: Emerson Electric Co., Emerson Process Management LLLP, Fisher-Rosemount Systems, Inc., Rosemount Inc., and BP America Inc. / BP America Production Company / BP p.l.c. (the Unified Patents page for this docket is even titled Sipco LLC et al. v. BP America Inc et al). Filed Oct. 16, 2015. Early motion practice included an opposed motion to dismiss or transfer and to stay, and a later opposed motion to sever and stay; SIPCO's Feb. 5, 2016 opposition (Dkt. 42) argued the first-to-file rule did not compel Georgia because the Georgia action concerned different patents. Ex Parte's docket summary reports the case closed July 1, 2016; a PTAB mandatory notice in IPR2017-00260 (concerning the '893 patent, also asserted here) states the case "has been transferred."

N.D. Ga. 1:15-cv-00319 — Emerson's preemptive declaratory judgment action.
Emerson Electric Co. v. SIPCO, LLC, Judge Amy Totenberg. Emerson filed this in Georgia on eight SIPCO patents while settlement talks were underway; it then abandoned all but two. SIPCO's E.D. Tex. briefing frames this as the case that created the first-to-file dispute.

N.D. Ga. 1:16-cv-02690 — SIPCO's Georgia action.
SIPCO, LLC et al. v. Emerson Electric Co. et al, Judge Amy Totenberg, filed July 26, 2016. This is the case Google Patents lists alongside the '780's "family has litigation" links.

PTAB IPR2016-00984 — decisive on validity.
Emerson petitioned Apr. 29, 2016; the Board instituted Nov. 2, 2016. The Final Written Decision of Oct. 25, 2017 held all challenged claims (1–15) unpatentable. Emerson's prior-art case included US 8,013,732 (SIPCO's own earlier patent in the '780 continuation chain), Kahn, "Advances in Packet Radio Technology," and Burchfiel, "Functions and Structure of a Packet Radio Station," plus admitted prior art. SIPCO's appeal turned on whether a certificate of correction to the '780 priority claim should have been given effect (which would have removed the '732 patent as prior art); the Board remanded decision (Jan. 24, 2020) did not change the outcome.

Fed. Cir. 2018-1364 — affirmance.
SIPCO noticed appeal Dec. 21, 2017. The appeal involved an initial remand under 35 U.S.C. § 144 to the Board (Order on Remand, Paper 52, Jan. 24, 2020), SIPCO's opening brief (Apr. 13, 2020) and reply (Aug. 7, 2020), and a final Rule 36 affirmance in January 2021 (per curiam: Prost, C.J., Mayer and Moore, JJ.).

3. What I could NOT confirm (do not treat as negative findings beyond this search)

• Any 2026 docket. No N.D. Ga., E.D. Tex., PTAB, or Fed. Cir. activity in 2026 involving 8,754,780 surfaced. Given expiration and the final adverse PTAB/CAFC outcome, this is expected — but treat it as a search result, not proof.
• Exact relationship between 6:15-cv-00907 and 1:16-cv-02690. The E.D. Tex. case is reported closed/transferred in mid-2016, with a separately numbered N.D. Ga. case filed weeks later. A transfer would normally retain the original case number, so I could not reconcile whether 1:16-cv-02690 is a re-filing, a related companion, or an unrelated matter that merely shares the parties.
• Exact filing date for 1:15-cv-00319 (only the year is indicated by the case number).
• Whether the '780 itself was asserted in 1:15-cv-00319. That case was Emerson's DJ action on eight SIPCO patents; I could not confirm the '780 was one of them versus being included in the family-litigation roll-up on the Google Patents page.
• The ITC Section 337 action referenced in the earlier summary of this patent. It did not surface in this pass; I have no docket or investigation number (e.g., 337-TA-___) for it and cannot confirm it involved the '780.
• Related IPR2019-00545 (Emerson Electric Co. v. SIPCO, LLC) appeared in search results near '780 materials but I could not confirm which SIPCO patent it targets; do not assume it is the '780.

Flagged inconsistency with the prior section: the earlier summary dated the final Fed. Cir. disposition to January 2021 and listed two competing FWD dates. The docket data now clarify the sequence — FWD Oct. 25, 2017 → § 144 remand → Decision on Remand Jan. 24, 2020 → Rule 36 affirmance Jan. 21, 2021 — resolving the "two FWD dates" ambiguity.

Verification note: all of this rests on secondary litigation databases (Unified Patents, Stanford NPE, Docket Alarm, RPX, Ex Parte). For an attorney-grade answer, confirm against PACER for the three district court dockets and against PTAB E2E / the Federal Circuit docket for IPR2016-00984 and 2018-1364, since the databases disagree on case titles, closure dates, and transfer events.

I'll verify the proceeding details against live sources before writing the analysis.

Let me pin down the post-remand Board decision and confirm whether any other AIA petitions targeted this patent.

Let me confirm no other AIA petitions hit this patent and verify the claim-cancellation certificate.

Proceedings overview

The structured "PTAB proceedings on file" block for US 8,754,780 is wrong (or fatally stale): it reports zero AIA trials, but this patent was the subject of one full IPR that went all the way through a Final Written Decision, a Federal Circuit remand, a second Board decision, and a Rule 36 affirmance.

Total AIA trial proceedings on US 8,754,780: 1 — IPR2016-00984, Emerson Electric Co. v. SIPCO, LLC. Breakdown: 1 with all challenged claims invalidated (claims 1–15), 0 active, 0 with claims sustained, 0 settled, 0 institution denials. Bottom line for a defendant today: this patent is not merely narrowed, it is dead — every one of claims 1–15 was held unpatentable by the Board on 2017-10-25, that decision was affirmed by the Federal Circuit on 2021-01-21, and the patent itself expired on 2018-06-22. Anyone still asserting US 8,754,780 is asserting canceled claims. If a demand letter cites the '780, the correct response is the IPR2016-00984 record plus the Rule 36 judgment, not a licensing negotiation.

Correction to the previously generated section: the earlier summary flagged a conflict between an FWD dated 2017-10-25 and a "final" dated 2020-01-24. There is no conflict — there were two decisions in this one IPR: the Final Written Decision (Paper 43, 2017-10-25) and the Decision on Remand (Paper 52, 2020-01-24), issued after the Court of Appeals remanded for the limited purpose of addressing a certificate of correction. Both are real; neither supersedes the other as to patentability. RPX's "Final: 01/24/2020" is the remand decision, not a new FWD.

IPR2016-00984 — Emerson Electric Co. v. SIPCO, LLC

• Type: Inter Partes Review (35 U.S.C. §§ 311–319), Tech Center 2600.
• Filed: 2016-04-29 (petition).
• Status: Final Written Decision issued; claims 1–15 held unpatentable; affirmed on appeal. No settlement, no termination by adverse judgment. (Note: the Docket Alarm copy of Paper 43 is misfiled under a filename containing the words "Termination Decision" — read the document, not the filename.)
• Judge panel: Lynne E. Pettigrew, Stacey G. White, and Christa P. Zado, Administrative Patent Judges; Zado authored the FWD. (RPX lists "Christa P. Zado +3," suggesting a fourth APJ was on the panel at some stage; I could only verify the three named in Paper 43 and in the 2017-07-13 hearing transcript.)
• Petition grounds: all 15 claims challenged under 35 U.S.C. § 103(a). Per the FWD's recitation of the institution decision (Paper 18):
  • claims 1–15 over U.S. Pat. No. 8,013,732 (the "'732 patent" — SIPCO's own grandparent patent, asserted as prior art because SIPCO's priority chain was broken by a clerical error in the domestic benefit claim);
  • claims 1, 2, 7 over Kahn in view of the admitted prior art ("APA");
  • claims 4–6, 8 over Kahn in view of the APA and Burchfiel.
    No § 101 or § 112 grounds were institution grounds.
• Institution decision: instituted 2016-11-02 (Paper 18). The Board's institution was modified/amended during the proceeding so that all challenged claims proceeded on all grounds presented in the petition — a point Emerson later litigated on a related appeal, where the Federal Circuit held the Board did not abuse its discretion in denying Emerson's request to introduce new evidence after that amended institution (37 C.F.R. § 42.23(b); Intelligent Bio-Systems v. Illumina Cambridge, 821 F.3d 1359 (Fed. Cir. 2016)).
• Final Written Decision: Paper 43, 2017-10-25, 2017 WL 4862106.
  • Verdict: "claims 1-15 of U.S. Patent No. 8,754,780 B2 … are unpatentable" — shown "by a preponderance of the evidence." Quote: "For the reasons discussed herein, we determine that Emerson Electric Co. … has shown, by a preponderance of the evidence, that claims 1-15 of U.S. Patent No. 8,754,780 B2 … are unpatentable."
  • Claim-level detail that is independently documented: the Federal Circuit's remand order records that the Board found claims 1–15 unpatentable on various grounds, "including finding that claims 3, 5, and 9–15 as obvious in view of the '732 patent." The Federal Circuit's opinion in the parallel '732-patent appeal records that the Board found "'780 patent claim 1 (and other claims) unpatentable over the same combination of Kahn and the Admitted Prior Art." Reading the two decisions together: independent claim 1 fell on Kahn + APA, while independent claim 9 (the thermostat claim) fell in the group invalidated over the '732 patent, and no claim of the '780 survived. A complete claim-by-claim ground mapping requires Paper 43 itself — I am quoting the Board's and the Court's own summaries, not the full text of the FWD.
  • Also noteworthy: the same panel (Pettigrew, White, Zado) decided the parallel IPR on the '732 patent (IPR2015-01973) and reached the opposite motivation-to-combine conclusion on nearly identical claims and evidence, which the Federal Circuit found inadequately explained and vacated (Emerson Elec. Co. v. SIPCO, LLC, No. 17-1866 (Fed. Cir. 2018-08-29)). The Board used the resulting inconsistency as grounds to press the parties on related IPRs, and criticized the parties for failing to disclose additional related petitions.
• Certificate of correction (the unusual feature of this proceeding): SIPCO had mis-identified a parent application in its domestic benefit claim, which broke co-pendency and left the '732 patent as prior art against its own later patent. SIPCO made four attempts at a § 255 certificate of correction: the first was stayed by the Board mid-IPR and denied (noncompliant, 2016); the second was dismissed 2017-01-19 (per one account; a separate Petitions Branch decision dismissing the second petition is dated 2017-03-31); the Board denied leave for a third request during the IPR; the Board then lifted the stay in the FWD and deferred to the Petitions Branch; the certificate issued 2018-03-27, five months after the FWD and three months after SIPCO's notice of appeal.
• Settlement / termination: none. This proceeding ran to judgment on the merits. (Separately, SIPCO and Emerson were adverse across multiple district court actions during this period, but there was no PTAB settlement.)
• Appeal: *Yes — SIPCO, LLC v. Emerson Electric Co., No. 18-1364 (Fed. Cir., notice of appeal filed 2017-12-21).*
  • SIPCO moved for remand in light of the newly issued certificate of correction. The Court granted a partial remand (order entered in the CAFC; reproduced in the PTAB record as Exhibit 2042, filed 2018-10-19), stayed the merits, and retained jurisdiction, directing the Board to address "what, if any, impact the certificate of correction has on its final written decision."
  • Decision on Remand: Paper 52, 2020-01-24 — the certificate of correction, which issued after the FWD and after the appeal was filed, has no impact on the Final Written Decision. The Board reasoned it would reach the same result either way: if an IPR is a "trial of actions" under § 255, the statute applies only to causes "thereafter arising"; if it is not, § 255 "does not contain any affirmative language indicating any intention to retroactively apply a certificate of correction." Practically, SIPCO's attempt to erase the '732 patent as prior art failed for this proceeding.
  • The merits were then briefed and argued in the Federal Circuit (the United States filed an amicus brief at the Court's request on 2021-01-11 addressing § 255). On 2021-01-21 the Court issued a Rule 36 judgment, AFFIRMED, nonprecedential, per curiam (Prost, C.J., Mayer and Moore, JJ.). Issues raised by SIPCO per the Fed Circuit Blog: whether the Board erred in denying leave to seek the certificate; whether the certificate mooted the '732-based obviousness findings; whether the Board relied on allegedly "uncontested" issues that were in fact disputed; and whether the Board relied on new evidence first presented in Emerson's reply and on the inventor's recognition of problems in the art as motivation to combine.

• Citation trap to avoid: Law360's PTAB case page headlined "PTAB Chops SIPCO Remote Monitoring Patent On Remand" (April 2020) and described the Board invalidating claims "after previously upholding" the patent — that posture (upheld, then vacated, then invalidated) matches the '732 patent proceeding (IPR2015-01973), not IPR2016-00984, which invalidated everything in the first instance. Law360's page also lists a filing date of 2015-09-25, which is not the '780 petition date. Do not attribute that article's outcome to the '780.
• Defensive value: Maximal. Every claim of the '780 — including both independents (1 and 9) and all dependents (2–8, 10–15) — was held unpatentable and the judgment was affirmed without opinion. An infringement theory built on claim 1 or claim 9 is not merely weak; it is inconsistent with a final, affirmed agency adjudication. The remaining tasks are evidentiary, not argumentative: pull Paper 43 and Paper 52, and confirm the § 318(b) certificate of cancellation.

Strategic summary

Claim status. Claims 1–15: ALL CANCELED/HELD UNPATENTABLE as of the FWD (2017-10-25), affirmed (2021-01-21). SURVIVING CLAIMS: none. UNTESTED CLAIMS: none — the petitioner challenged the entire claim set from the outset, so there is no unadjudicated fallback claim. Two caveats worth stating precisely rather than glossing: (1) 35 U.S.C. § 318(b) requires the Director to issue a certificate canceling claims "finally determined to be unpatentable" only after the time for appeal has expired or any appeal has terminated, so the formal cancellation certificate could not have issued before early 2021 — I have not verified the face of that certificate, and a defendant should confirm cancellation in USPTO Patent Center before writing "claims 1-15 are canceled" in a brief. (2) Google Patents lists an anticipated expiration of 2018-06-22 and a status of "Expired – Fee Related"; that date is an assumption derived from the 1998-06-22 priority date and should likewise be confirmed against maintenance-fee records. Either way, no damages period after mid-2018 is plausible.

Estoppel landscape. Section 315(e)(2) estops Emerson Electric Co. and its privies — plausibly the Emerson-family defendants named in the E.D. Tex. action (Fisher-Rosemount, Rosemount, Emerson Process Management, and the BP entities joined in 6:15-cv-00907) — from asserting in litigation any ground they raised or reasonably could have raised in IPR2016-00984. That estoppel is now largely academic because the grounds succeeded. For a new, unaffiliated defendant, § 315(e)(2) does not apply, but there is nothing left to challenge. The strategically important asymmetry is this: a new challenger could still run Emerson's Kahn + APA obviousness theory against claim 1 (that ground was not art-specific to SIPCO's own patents), but could not run the '732-patent ground that took out claims 3, 5, and 9–15, because the § 255 certificate of correction issued 2018-03-27 operates prospectively on any later-filed proceeding — meaning the '732 patent is not prior art to the corrected '780. The Board's Paper 52 ruling is expressly limited to the pre-existing proceeding; it does not bless the '732 as prior art generally. That is the one respect in which SIPCO's correction campaign succeeded.

Pattern signals. This was a single-petitioner, single-petition, single-panel matter — no joinder, no follow-on petition, no defensive aggregator (no Unified Patents or RPX filing on the '780 appears in the record). Emerson was a serial filer against the Petite/SIPCO family, though: the FWD itself notes Emerson petitions on US 8,013,732 (IPR2015-01973) and US 6,914,893 (IPR2015-01579), and the appellate record shows a CBM on US 8,908,842 (CBM2016-00095, 18-1635, decided 2020-11-17). SIPCO litigated the PTAB outcomes aggressively upward — it appealed the '780 FWD, moved for remand on the certificate of correction, retained Finnegan and then Gonsalves, and obtained a § 255 question of first impression briefed with the Solicitor as amicus. It lost. The '780 proceeding also became the evidentiary yardstick used by the Federal Circuit to vacate the Board's contrary ruling on the near-identical '732 patent (17-1866), which is a useful signal that the '780 FWD is the more robust of the two decisions and was not disturbed on any substantive ground.

Recommended next steps

1. If defending against an assertion of US 8,754,780: obtain Paper 43 (FWD, 2017-10-25) and Paper 52 (Decision on Remand, 2020-01-24) from PTAB E2E for case IPR2016-00984, and the Rule 36 judgment in SIPCO, LLC v. Emerson Elec. Co., No. 18-1364 (Fed. Cir. 2021-01-21) (https://www.courtlistener.com/opinion/4849236/sipco-llc-v-emerson-electric-co/). Cite the FWD's disposition verbatim — "claims 1-15 … are unpatentable" — and pair it with the affirmance. Confirm via Patent Center whether the § 318(b) cancellation certificate has issued, and confirm the expiration date, before pleading either.
2. Do not reinvent the wheel. There is no active proceeding, no live trial deadline, and no FWD due date to track: the IPR terminated with the 2021-01-21 Rule 36 mandate. If someone proposes filing a fresh IPR on the '780, the answer is that the patent expired in 2018 and its claims were invalidated in 2017–2021; a new petition would be a cost with no defensive dividend.
3. Look to the siblings instead. SIPCO's value in this family sits in the continuations and related patents (e.g., US 8,013,732, US 8,212,667, US 7,978,059, US 7,468,661, US 7,053,767, US 6,437,692, US 6,430,268, US 8,908,842, US 6,914,893), several of which drew their own AIA trials. If SIPCO or a successor is asserting "remote monitoring" claims today, the demand is far more likely to rest on one of those — map the assertion to the correct patent before assuming the '780 IPR is the whole defense.
4. Preserve the certificate-of-correction argument. If any related patent in this family has the same broken priority chain (the chain recited in the '780 and '667 specifications contains the same mis-identified parent), a defendant should check whether a § 255 correction is needed and whether it can still be given effect — Paper 52's holding is that a correction issued after an FWD and after the notice of appeal is ineffective in that proceeding. Timing matters; that is precisely the trap SIPCO fell into.

Uncertainties I am not papering over: the full claim-by-claim ground mapping in Paper 43 (I have the Board's and the Court's summaries, not the whole text); the exact date of the Federal Circuit's remand order (one secondary source says 2018-06-27; the copy in the PTAB record was filed 2018-10-19; the docket entry itself I did not retrieve); whether a fourth APJ sat on the panel; the date of the second Petitions Branch dismissal (2017-01-19 vs. 2017-03-31 across sources); the issuance of the § 318(b) cancellation certificate; and the true expiration date. Also, one artifact I could not reconcile: SIPCO's Patent Owner Response in IPR2016-00984 has a table of contents referencing "sensor (claims 13, 20, 26 and 31)," which cannot describe the '780's 15-claim set — it appears to be templated or bundled from a related IPR (the '732 or '511 patent). It does not change the FWD's scope, which unambiguously covers claims 1–15, but do not rely on that response's headings for '780 claim numbering.

I'll research the assignment record for US 8,754,780 before reconstructing the chain.

Good — I found partial reel/frame data. Let me dig into the specific assignment records and correspondent.

Let me pin down the specific reel/frame entries and correspondents for the '780 itself.

Ownership & Assignment Analysis — US 8,754,780 B2

Sourcing caveat up front. My session could not render the USPTO Assignment Center's per-record detail view (assignmentcenter.uspto.gov) or the Assignment Search legacy interface (assignment.uspto.gov/patent/index.html). The records below were reconstructed from (a) Google Patents legal events for the '780 itself, (b) chain-of-title tables reproduced verbatim inside PTAB exhibits — i.e., the filed assignment paperwork for family members US 6,430,268 and US 6,914,893 (Docket Alarm, IPR2019-00545 Exhibits 1025/1030), (c) Plainsite patent-assignment index, and (d) the docket in SIPCO v. B&L Tech, N.D. Ga. Where I could not retrieve a reel/frame for a '780-specific record, I say so rather than back-filling from a sibling patent. Verify each line at the Assignment Center search by patent number 8754780.

Inventors

Pattern note — and it is the inverse of the usual tell. The classic fire-sale precursor is "all inventors depart the original assignee within 12 months of filing." That did not happen here. Both inventors stayed inside the corporate family for two decades: Petite is named as President of plaintiff SIPCO, LLC in the 2009 S.D. Fla. complaint and is described in SIPCO v. Emerson (N.D. Ga. 1:16-cv-02690, Pls.' Mot. to Dismiss, Dkt. 116) as a "prolific and pioneering inventor" who remains "actively involved in SIPCO's product development and business activities." The unusual pattern is the opposite one: the inventors stayed put and the corporate vehicle changed around them — the canonical "individual-inventor-started NPE" profile that the Stanford NPE Litigation Database assigns to this patent under asserter category "5 – Individual-inventor-started."

Original assignee

SIPCO, LLC, Atlanta, GA is the entity named on the face of US 8,754,780 (Google Patents: "Original Assignee: Sipco LLC"; application-data sheet for the family: "Assignee Name: SIPCO, LLC"). This is the second-reported inconsistency in the prior section, and it is real: the face page says SIPCO, but the recorded chain shows the inventors assigned first to StatSignal Systems, Inc. — SIPCO obtained title later, via the 2004–2007 and 2014 recordings below.

• Primary line of business: patent licensing / IP monetization. Per the iKnow industry analysis, SIPCO was formed to hold and maintain the "bidirectional RF mesh" intellectual property — "patents, software, firmware, hardware design" — i.e., a licensing-only entity. RPX describes it flatly as "SIPCO LLC, a Georgia-based NPE co-founded by inventor T. David Petite."
• Does it ship a product embodying the claims? No evidence of any commercial product. In SIPCO v. X10 (E.D. Tex. 2:08-cv-00359, Dkt. 149) SIPCO argued only that it has "an office" in the Eastern District of Texas and "no operations, offices, employees, documents, or witnesses in Washington" — an operating profile, but no product line.
• Current status: Operating as a licensing entity, not dissolved. Corporate-level control has changed repeatedly without a patent-level assignment (see caveat below): RPX reports General Electric and MPEG LA acquired part-ownership stakes in 2012, and that by early 2018 SIPCO disclosed it was wholly owned by Glocom, Inc., a Maryland company linked to the CEO of Korean monetization firm Ideahub, Inc. None of those equity events generate a USPTO assignment record.

Assignment timeline

Scope note: Lines marked [family record] are reel/frame entries retrieved from the reproduced chain-of-title tables for sibling patents (US 6,430,268 and US 6,914,893) — the same conveyances that carry the '780's title. Lines marked [780 record, no reel/frame retrieved] are the '780's own legal-events entries. I am not manufacturing reel/frame numbers for the latter.

Per the March 31, 2004 "Intellectual Property License and Assignment Agreement" quoted in the B&L order, SSI assigned the "Assigned Patents" to IPC for $1.00 plus consideration — a related-party reorg that split utility-industry rights (kept by B&L) from non-utility rights (granted to SIPCO). Goldman is also the attorney whose e-mail address (joel@goldmaniplaw.com) appears on 2010 USPTO correspondence for the family and who was deposed as SIPCO's counsel in the B&L case — a recurrence, flagged in Signal 3.

Ga. court granted SIPCO's "Renewed Motion for Partial Summary Judgment on Reversion Claim" (Dkt. 343, July 17, 2008) and the parties were litigating a right-of-first-offer and a receiver appointment over a financially distressed B&L/StatSignal. A judicial-decree conveyance is a strong indicator of contested or distressed title, not a clean commercial sale.

Contradiction to flag. The prior section's chain reads "Huff & Petite → Statsignal Systems → Hunt Technologies → SIPCO," matching Google Patents' events 7–9. The family chain-of-title tables, however, interpose StatSignal IPC, LLC between Statsignal Systems and Hunt Technologies (lines 2 and 4 above), and show a judicial decree as the vehicle that put the assets into SIPCO. Both are supported by primary documents. My read is that the 2014 recordings consolidated a single "clean" chain for the new continuation and omitted the intermediate IPC hop. But I cannot reconcile this from the data I retrieved — treat the '780's 2014 reel/frame and the identity of the intermediate assignee as unresolved.

• Conveyance: SECURITY INTEREST
• Assignor: SIPCO, LLC
• Assignee: ROBBINS GELLER RUDMAN & DOWD LLP
• Correspondent: not retrieved
• Context: Securitization — a contingency-fee plaintiffs' securities firm taking a security interest in the patent estate. Unusual counterparty for a security agreement; consistent with litigation-financing/fee-security arrangements rather than an ownership transfer.

No assignment of the '780 away from SIPCO, LLC is recorded through the analysis date. All corporate-control changes (GE, MPEG LA, Glocom/Ideahub) occurred at the equity level and are invisible in the patent assignment record.

NPE / troll-pattern signals

1. Shell-entity transfer — PRESENT.
US Patent 8,754,780's title terminates at SIPCO, LLC, a licensing-only entity. The documentary support is the March 31, 2004 IP License and Assignment Agreement (quoted in the B&L order and recorded at reel 015788/0684), under which the operating entity StatSignal Systems conveyed its patents to a purpose-built IP holder, and RPX's classification of SIPCO as "a Georgia-based NPE." The §1.00 consideration recited in reel 015788/0684 is the classic related-party reorg signature. Limitation: SIPCO's Atlanta address is a real commercial office, not a registered-agent mail drop, and I found no evidence it is a single-member Delaware shell — so this is a reorg-to-licensing-entity finding, not a classic "anonymous shell" finding.

2. Known asserter in the chain — PRESENT.
SIPCO, LLC is the current assignee of record and is listed in the Stanford NPE Litigation Database against patent 8754780 (asserter category "5 – Individual-inventor-started"), and RPX's own news feed calls SIPCO an NPE. SIPCO is not on the specific roster cited in the prompt (Acacia, Marathon, IV, Wi-LAN, Conversant, Vringo, Pendrell, etc.), but the prompt's list is illustrative ("plus any entity surfaced by Unified Patents or RPX as a high-frequency plaintiff") — SIPCO fits squarely: the RPX piece "Smart Parking System Providers Sued in Mesh Networking Campaign" (Sept. 22, 2016) recounts a ten-patent SIPCO/IP Co. campaign, and the Stanford database lists at least two '780 suits. Present on the RPX/Stanford prong.

3. Repeat correspondent across the chain — PRESENT (moderate).
Two recurring names, neither of which is a single-appearance:

• Joel S. Goldman — correspondent of record on the pivotal 2004 restructuring assignment, reel 015788/0684; simultaneously the family's outside prosecution counsel (his e-mail appears on the 2010 USPTO address-change correspondence for application 09/102,178, Customer No. 89818) and the SIPCO-side deponent in SIPCO v. B&L. One attorney spanning recording, prosecution and litigation for the same portfolio is the recurrence pattern the prompt asks for.
• Troutman Sanders LLP (James H. Yancey, Jr.) — the family's Customer No. 006980/89818 correspondent; named as legal representative of record for the '268 family's post-issue assignments, and the attorney whose address appears on the '780's application data sheet. Different firm on the 1998 and 2015 links, however: Thomas Kayden Horstemeyer & Risley (1998) and King & Spalding, attn. Susan Lake, paralegal, 1180 Peachtree Street, Atlanta GA 30309 (2015 security/release). So the correspondent is not constant across all eleven links — hence moderate, not strong.

4. Cascading transfers — PRESENT.
Six recorded conveyances touch the family between 1998 and 2007 (reels 009280/0335 → 015788/0684 → 018951/0985 → 019069/0193 → 019541/0166 → 019541/0185), followed by three same-day recordings on 2014-06-09 for the '780 itself. The 2014 cluster — three linked LLC/corporate hops recorded within 24 hours — is the textbook chained-transfer footprint.

5. Pre-litigation transfer — NOT PRESENT.
The '780's own chain-of-title recordings are dated 2014-06-09; the first suit naming the '780 (SIPCO v. Emerson, E.D. Tex. 6:15-cv-00907) was filed October 16, 2015 — roughly 16 months later, well outside the 6-month window. The 2019-11-19 security interest and 2020-08-05 release post-date the litigation. Nothing in the record shows a transfer timed to enable assertion.

6. Bankruptcy fire-sale — UNCLEAR.
I found genuine distress markers around B&L Tech / StatSignal Systems: a contested motion to appoint a receiver for B&L (Dkt. 371, Aug. 2008), a right-of-first-offer/reversion fight decided on partial summary judgment, and the resulting judicial decree recorded at reel 019541/0166. But I did not find a Chapter 7 or Chapter 11 filing, a bankruptcy-court sale order, or a §363 sale. Distress ≠ bankruptcy; I decline to call this present.

7. Privateering — UNCLEAR.
RPX reports that General Electric and MPEG LA each took part-ownership stakes in SIPCO in 2012, and that SIPCO is now wholly owned by Glocom, Inc. (Maryland), tied to the CEO of Korean monetization firm Ideahub, Inc. GE and MPEG LA are operating/standards entities acquiring interests in an asserter — that rhymes with privateering. But I found no SEC filing, complaint, or Patent Progress/EFF coverage showing that GE or MPEG LA directed SIPCO's assertions against their competitors. An equity stake alone is not a privateering finding.

8. Defensive aggregator — NOT PRESENT.
No RPX, Allied Security Trust, LOT Network, Unified Patents, or OIN entity appears anywhere in the chain. The chain terminates at SIPCO, LLC (an asserter) after the 2020 release; the patent has not been neutralized.

Additional non-signal worth recording: the 2019-11-19 security interest to Robbins Geller Rudman & Dowd LLP, released 2020-08-05. A plaintiffs' securities firm as secured party over a patent portfolio is a financing arrangement, not an NPE transfer — but it is the kind of encumbrance that tells you the portfolio was being used as collateral against litigation receivables.

Verdict

NPE — high confidence.

US 8,754,780 is owned at the patent level by SIPCO, LLC, a licensing-only entity with no product embodying the claims, which RPX and the Stanford NPE Litigation Database both classify as an NPE, and which has run a multi-year assertion campaign naming this patent (e.g., SIPCO v. Emerson, E.D. Tex. 6:15-cv-00907; N.D. Ga. 1:16-cv-02690). The two strongest documentary signals are (i) the 2004 assignment at reel 015788/0684, which moved the portfolio out of operating company StatSignal Systems into a purpose-built IP holder for $1.00 plus consideration, and (ii) the three same-day 2014-06-09 recordings that consolidated the '780's chain into SIPCO at issuance. The chain is not defensive — no RPX/AST/LOT/OIN entity appears — and it never moved pre-litigation (2014 recordings precede the 2015 suit by ~16 months), so the transfer timing does not independently corroborate assertion-driven restructuring.

Verification links:

• USPTO Assignment Center — https://assignmentcenter.uspto.gov/ (search patent number 8754780)
• USPTO Assignment Search (legacy) — https://assignment.uspto.gov/patent/index.html (search 8754780)
• Google Patents legal events — https://patents.google.com/patent/US8754780/en
• Stanford NPE Litigation Database — https://npe.law.stanford.edu/patent/8754780

Open items I could not close: the '780's own reel/frame numbers for the 2014 and 2019/2020 recordings; the correspondent of record on those four '780-specific entries; and whether StatSignal IPC, LLC is a necessary link in the '780's chain or only in the siblings'. These require the Assignment Center detail view, which my session could not render.

I'll research the specific cited references for US 8,754,780. Let me run several targeted searches.

Let me pull the front-page references and the IPR petition's prior-art set.

Prior-Art Analysis — US 8,754,780 B2

Retrieval limitation stated up front (read before using the tables):

I searched for US 8,754,780 and its citation record. I could not retrieve the printed "(56) References Cited" block for this patent. The authoritative Google Patents text supplied for this analysis contains the front matter, classifications, abstract, description and figures — but no references-cited section, and the USPTO PatentCenter/Full-Text view was not directly queryable in my searches. Google Patents, Sumobrain, FreePatentsOnline and Espacenet all returned the same truncated bibliographic shell.

So I cannot give you a verbatim list of the examiner-cited references. What follows is (a) an explicit statement of that gap, and (b) the prior art I can substantiate with citations from the IPR/appellate record and the patent's own specification. I have labeled every entry by source and confidence. I have not reconstructed or guessed at the (56) list. Any analyst needing the face-of-patent citations should pull the grant PDF directly (patentimages.storage.googleapis.com mirror of the USPTO grant) or PatentCenter for application 13/855,452.

One literal-identifier warning: search results surfaced US 5,875,478 (Blumenau, Feb. 1999) adjacent to this number. That is a different patent and is not US 8,754,780. I have not treated it as related.

0. The date gate that governs every § 102 question here

US 8,754,780 claims priority to June 22, 1998 (09/102,178). Under pre-AIA § 102 as applied to this family:

• § 102(b) critical date: June 22, 1997
• § 102(a)/(e)/(g) critical date: June 22, 1998

Every reference published or filed after June 22, 1998 is presumptively not § 102 prior art against these claims — unless a petitioner first breaks the priority chain. That is the pivot of the entire prior-art story on this patent, and it explains why the real art is 1970s packet-radio literature rather than the 2000s smart-meter references that appear in "cited by" lists.

1. Documents cited in the '780 specification (priority/incorporation-by-reference family)

These are the "patent citations" that appear in the '780 text itself (col. 1, Cross Reference section). None of them can anticipate claims 1–15, because they are same-family/same-inventive-entity documents sharing the contested priority chain and are incorporated by reference. Listed for completeness and because their filing dates matter to any priority-attack theory:

Dates for the issue dates above are as I hold them; the application numbers, filing dates and titles come from the '780 Cross-Reference paragraph itself and are high confidence. Verify the issue dates against the grant PDF before filing anything.

2. The prior art actually litigated against the '780 — IPR2016-00984

This is the operative prior-art set for US 8,754,780. Identified from the IPR record and from expert testimony in the proceeding (ptacts.uspto.gov petition file 1475714):

Outcome of that proceeding: all challenged claims (1–15) held unpatentable; the Federal Circuit affirmed (No. 2018-1364, per curiam, Jan. 21, 2021, Fed. Cir. R. 36).

3. § 102 claim-level mapping (preliminary)

Applying the 1998 priority date and the claim structure described in the earlier analysis:

Bottom line for § 102: the only reference in the substantiated set that has a genuine single-reference anticipation theory against an independent claim is Kahn (1978) against claim 1, with the packet-radio relay-plus-own-address feature doing the work. Everything else is better characterized as § 103 territory — consistent with the PTAB invalidating all claims and the Federal Circuit affirming.

4. Related record: the '692 patent and "Cunningham"

In Emerson Electric Co. v. SIPCO, LLC, 980 F.3d 865 (Fed. Cir. 2020), the court held that "substantial evidence supports the Board's findings that Cunningham fails to disclose a 'control signal.'" That reference was asserted against the '692 patent (US 6,437,692, a shared-priority sibling), not US 8,754,780. I have not verified Cunningham's bibliographic identity (patent number, publication date), so I am deliberately not citing a number for it. If you need it, pull it from the '692 IPR/JA record.

The same decision notes the earlier SIPCO/Emerson appeal, 939 F.3d 1301 (Fed. Cir. 2019) (construing "low-power transceiver" for the '842 patent), was vacated — Emerson Elec. Co. v. SIPCO, LLC, 207 L. Ed. 2d 1049 (2020).

5. Contradictions and defects I am flagging explicitly

1. The '780 priority paragraph is chronologically impossible as printed. It recites that 09/102,178 (filed 1998-06-22) "is a continuation-in-part of" 09/412,895 (filed 1999-10-05). An application cannot be a CIP of a later-filed application. The CIP chain in the specification is garbled. This is exactly the kind of defect a petitioner exploits when attacking the June 22, 1998 priority date — and attacking that date is the only way post-1998 references (including US 8,013,732) become available as art.
2. 09/271,517 is "ABN" (abandoned) in the USPTO filing receipt excerpted in the IPR record, while the '780 specification treats it as an operative CIP parent. Abandonment does not destroy a priority link, but it does mean § 112 support must be traced application-by-application.
3. The IPR final-written-decision date is reported inconsistently. Patexia shows a decision date of Oct. 25, 2017; RPX Insight shows Final: Jan. 24, 2020; both list the appeal as 18-1364, decided Jan. 21, 2021. This is consistent with an initial FWD followed by a further Board decision after remand/vacatur, but I could not confirm which. Unresolved.
4. Claim-set characterization is inherited, not re-verified. The earlier section's "two independents (1 and 9), 15 total claims" is corroborated by the IPR (claims 1–15 challenged) but I did not re-read the printed claim set. In particular, the recitation that claim 9 is a "thermostat device" drives my conclusion that Kahn cannot alone anticipate claim 9 — verify that against the grant PDF before relying on it.
5. Forward citations are not prior art. References such as US 10,162,327 (thermostat) and US 11,108,585 (pool chemical controllers) cite the '780 as background. They post-date it and are irrelevant to § 102.

6. What I could not determine

• The actual examiner-cited (56) references on the face of US 8,754,780 — not retrievable from the sources available to me.
• The full ground set of IPR2016-00984 (I have Kahn, Burchfiel, the '732 patent and "admitted prior art"; a typical petition would include additional primary/secondary references).
• Cunningham's full citation.
• Whether Emerson expressly attacked the 1998 priority claim (my § 2 inference that this is why a family member appears in the record is unverified).

Recommended verification path: (1) grant PDF for the (56) list and exact claim text; (2) IPR2016-00984 Petition and Exhibit list via PTAB/Unified Patents portal; (3) the Jan. 21, 2021 Rule 36 judgment and the Jan. 24, 2020 FWD to resolve the date discrepancy.

I'll ground the obviousness analysis in the actual prior-art record for this patent family. Note upfront: the page text supplied to me does not include a "Prior Art"/"Citations" section — the fetched Google Patents text is truncated mid-sentence ("Having illustrated a") and contains only the abstract, description, and classifications. So I'll reconstruct the prior-art record from the IPR/litigation record and say explicitly where I'm inferring.

Now let me pin down the specific reference identities and the Board's reasoning.

Let me verify the claim language and the cited references on the '780's face, since the supplied page lacks both.

Obviousness of US 8,754,780 B2 under 35 U.S.C. § 103

0. Provenance note — the "Prior Art section" of this page

You asked me to use "the results from the Prior Art section of this page." That section does not exist in the material supplied to me. The fetched Google Patents text is truncated mid-description ("Having illustrated a") and contains no Patent Citations, Referenced By, Prior Art Keywords (beyond the five-term tag list "transceiver / data / controller / sensor / control"), or Similar Documents block. I therefore did not invent one; instead I grounded this analysis in the actual, citable prior-art record for this patent: IPR2016-00984 (Emerson Electric Co. v. SIPCO, LLC), which is the one proceeding in which the full claim set 1–15 of this patent was adjudicated on § 103 grounds.

Two housekeeping items:

• Trivial date conflict. The supplied page header says "Fetched: 2026-09-21"; this task states "Current Date: April 26, 2026." Non-material to the analysis; flagging per instructions.
• A prior-section uncertainty is now resolved (not contradicted). The earlier "two FWD dates" mystery (Oct. 25, 2017 vs. Jan. 24, 2020) is not a conflict: Oct. 25, 2017 is the original Final Written Decision (Paper 43) and Jan. 24, 2020 is the Board's Decision on Remand (Paper 52, 35 U.S.C. § 144 / 37 C.F.R. § 42.5(a)), issued after the Federal Circuit's partial remand in No. 2018-1364.

1. Framework applied

The Board adjudicated this patent under pre-AIA § 103(a) (the '780 was filed April 2, 2013 as a continuation into a 1998 chain, and the Board cited § 103(a), not § 103 post-AIA). That matters here because it licenses use of Applicant Admitted Prior Art (AAPA) — the specification's own "prior art control system 100" of FIG. 1 — as a § 103 reference base.

The governing test is Graham v. John Deere, 383 U.S. 1 (1966), as glossed by KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007) — both cited in the '780 record. No teaching-suggestion-motivation requirement; the question is whether the combination is "a predictable variation of the prior art" supported by "articulated reasoning with some rational underpinning."

POSITA. The closest recorded definition is from Emerson's sibling '708 petition: a bachelor's degree in EE/CE/CS or related field plus two or more years' experience in design of wireless communication systems, with the understanding of how to design wireless multi-hop monitoring/control networks. I did not retrieve the '780-specific POSITA formulation (Emerson's '780 expert was Dr. Heppe, Ex. 1018; SIPCO's was Dr. Almeroth, Ex. 2001). Treat the above as a proxy.

2. What has to be covered

Claim 1 (verbatim, per PTAB and RPX) requires three things of the claimed device: (a) a transceiver with a unique ID electrically interfaced with a sensor that receives select information + ID from a second transceiver in a predetermined signal type; (b) the transceiver wirelessly retransmits the select information, the second transceiver's ID, and its own ID; (c) a controller coupled to both transceiver and sensor that receives sensor data and formats a data packet comprising data representative of the sensed data.

Claim 9 is the same architecture recited as a thermostat device. The dependent limitations (per the earlier section) fall into four buckets: function-code limitations (4, 5, 6, 8, 13), actuator/control-signal limitations (2, 7, 14), device-type limitations (3, 9–12), and proximity/ID-programmability limitations (8, 11, 15).

The structural gap in the existing record. Ground 1 (see § 3) reached all claims 1–15, but Grounds 2 and 3 reached only claims 1, 2, 4, 5, 6, 7, 8. The Federal Circuit's remand order confirms the Board found claims 3 and 9–15 unpatentable only "in view of the '732 patent." Since the '732 patent's prior-art status is now legally fragile (§ 3), claims 3 and 9–15 are the ones that need fresh combinations today — and they include the thermostat independent claim 9.

3. Ground A — the prior art the Board actually used

Reference identities are confirmed from Petitioner's Reply (Paper 25) exhibit list in IPR2016-00984 (docketalarm).

Do-not-conflate warning (literal-ID discipline). A PTAB record for a different proceeding involving the '732 patent lists Ex. 1002 = Kahn and Ex. 1001 = the '732 patent (ptacts artifact). In IPR2016-00984, Kahn is Ex. 1015 and Burchfiel is Ex. 1016. Do not port the other docket's numbering across.

3.1 Element mapping (Kahn + AAPA, optionally + Burchfiel)

3.2 Motivation to combine (the crux)

The Board and Petitioner articulated two independent rationales, and the Federal Circuit let both stand:

1. Kahn's express reasons. Kahn states PR-network "flexibility in rapid deployment and reconfiguration not currently possible with most fixed plant installations," plus support for mobile users and bursty traffic; "Deployment of the packet radio net should be rapid and convenient, requiring little more than mounting the equipment at the desired location" (Kahn 1468–70). That is a facially sufficient, non-hindsight rationale: a POSITA would adopt a wireless multi-hop network precisely to avoid pulling cable.
2. The AAPA's own admitted problem. The '780 specification admits that prior-art systems "require electrical coupling between the local controller and system sensors and actuators," and that "appropriately wiring an existing industrial plant can be a dangerous and expensive proposition" (Ex. 1001, 5:56–6:3). Petitioner used this as a "known problem" motivation.

Reasonable expectation of success was supplied by Dr. Heppe: prior-art sensors and actuators intended for third-party integration have well-defined behaviour and interface specifications, enabling integration with Kahn's PR network "with relative ease (i.e., without undue experimentation), and with predictable results" (Ex. 1018 ¶ 42) — a KSR "predictable variation" argument.

Secondary considerations. None are recorded as having been presented in the '780 IPR. Apparent reason: the asserted claims were being litigated against Emerson, and the patent expired June 22, 2018, foreclosing most commercial-success nexus arguments.

3.3 Burchfiel's role (function-code claims 4, 5, 6, 8)

Burchfiel discloses a "function field" in the packet and control functions performed by the radio station — "establishing control, debugging, and measur[ing] connections from the station to each repeater." The Board construed "function code" = "bits of data corresponding to a function" and "function" = "features or parameters of a system, and capabilities and tasks to be performed," then found the combination taught the function-code limitations of claims 4, 6, and 8 (and claim 5 was within Ground 3 as instituted). This construction is doing most of the work — see § 8.

4. Ground B — the '732 patent ground is now legally hollow

Ground 1 held all of claims 1–15 obvious over US 8,013,732 — but only because the '780's priority claim was defective (a clerical mis-identification of a parent application), which made the '732 available as § 102/§ 103 art even though it shares the specification.

The chain of events: SIPCO's first, second, and third correction petitions were dismissed; the Board stayed further attempts; the fourth request was granted Feb. 8, 2018 and the certificate of correction issued March 27, 2018. On remand the Board held the certificate had no impact, reasoning that § 255 makes a correction effective on "the trial of actions thereafter arising" and SIPCO's correction came after the petition was filed (Decision on Remand, Paper 52, Jan. 24, 2020).

Analyst consequence: for any future challenge or case, the '732 patent should not be counted on as prior art. Under § 255's prospective operation it appears to be removed as a reference. That means:

• Grounds 2 and 3 (Kahn + AAPA [+ Burchfiel]) carry the durable weight for claims 1, 2, 4–8.
• Claims 3 and 9–15 lack any Kahn-based ground in the existing record and must be attacked with a new combination.

5. Ground C (new) — Kahn/AAPA/Burchfiel + HVAC art, for the thermostat claims 9–15

Claim 9 differs from claim 1 only in reciting a thermostat device. The structural elements are therefore carried by Ground A. The missing element is the thermostat, plus (for claim 12) a network-coupled user device supplying temperature control signals, and (for claims 2/7/14) an actuator implementing command data.

Available art, all of which is already in the SIPCO family record and therefore fails the "not previously considered" test less cleanly but is substantively strong:

Motivation. (i) Kahn's own express rationale — a thermostat is the paradigmatic hard-wired sensor/actuator node, and replacing its control wiring with a rapidly deployed wireless network is exactly the "known technique applied to a known device ready for improvement" that KSR sanctions; (ii) the AAPA admits its local controller "returns control signals as appropriate to the system actuators," so remote actuation of a set-point changer is an admitted capability; (iii) user demand for remote temperature control over a WAN was commercially evident; (iv) Cunningham supplies the explicit HVAC-actuator-adjustment teaching, removing any doubt about the thermostat recitation.

6. Ground D (new) — meter/system art for claim 3 and the double-append concerns

For claim 3 (device type: utility meter, rain gauge, in-vehicle, mobile inventory, irrigation, wearable), the art set developed against the sibling patents is directly on point and the mappings transfer because the patents share the specification:

• U.S. 6,100,817 (Mason) — ANSI CEBUS RF automatic meter reading; meters 12A–12C talk to node 18, and meter 12C acts as a repeater to reach "inaccessible" meter 12D. Six meters/four-node topologies are the claim-3 subject matter.
• U.S. 5,874,903 (Shuey) — repeater details: a repeater "creat[es] a modified message" that "is formatted to be receivable by another meter," including implementing repeater addresses to route a message through two repeating meters. This is the closest art to the narrowest limitation of claim 1 — retransmitting both the upstream ID and the relaying node's own ID (see § 8).
• ANSI C12.18 (1996) — packet/frame structure (§ 102(b) art).
• U.S. 6,208,266 (Lyons), US 6,124,806 (Cunningham) — remote meter imaging/monitoring with networked management controllers.

The Board in the parallel '492 FWD (IPR2016-01895) held Mason + Shuey + C12.18 rendered unpatentable claims substantially overlapping those of the '708; Emerson made the same argument in IPR2019-00547. That is a proven, Board-accepted combination, not a hypothesized one.

7. Motivation-to-combine ledger

8. Where this obviousness case is genuinely contestable

1. The double-ID retransmission limitation (claim 1(b)). This is the point on which SIPCO concentrated. Its position was that Kahn teaches away from retransmitting the identification information of both a nearby transceiver and the relaying transceiver; that the Board's finding rested on impermissible hindsight; and that the "self-initializing / self-organizing" motivation was unsupported. The Board nonetheless found Kahn's "entire set of selectors in its header" disclosure sufficient, supported by Heppe. Shuey's "modified message"/"repeater addresses" disclosure is the better, cleaner secondary reference and should be added in any fresh attack.
2. The "function code" construction. The Board's construction ("bits of data corresponding to a function"; "function" = tasks/capabilities) is broad and carried claims 4–6 and 8. Under Phillips in a district court, SIPCO would press its narrower construction ("a symbol representing a function," "a relation from a domain to a codomain…") — if adopted, Burchfiel's function field likely falls short. This is the single biggest fragility in Ground 3.
3. AAPA as a reference base. The Federal Circuit has cautioned against "using that which the inventor taught against its teacher" (W.L. Gore v. Garlock). SIPCO argued the "cost of wiring" problem was the inventor's recognition, not a known art problem. The Board rejected that; the Rule 36 affirmance means the argument failed to produce reversal, but an Article III court is not bound by a Rule 36 disposition.
4. Priority-dependent ground. As noted, Ground 1 should not be relied on going forward — and claims 3 and 9–15 have no non-priority ground in the record. Any current invalidity theory for claim 9 must be built, not cited.
5. Claim 11 (electrically programmable unique ID). I found no clearly mapped disclosure; Kahn's selectors are "preassigned," which is not the same as electrically programmable. Flagging this as the limitation I am least able to support from the record I retrieved.

9. Explicit uncertainties

• No Prior Art section was provided. Reference identities come from the IPR2016-00984 docket, not from the page you asked me to use.
• Reference dates/§ 102 bases for Cunningham (US 6,124,806, issued Sept. 26, 2000), Mason (US 6,100,817, filed Mar. 17, 1998), Lyons (US 6,208,266, filed Apr. 28, 1997) and Ehlers are taken from secondary sources (ITC FID; PTAB petitions); I did not verify their filing dates against USPTO records. For a June 22, 1998 priority date, pre-AIA § 102(e) availability is the crux and must be checked claim-by-claim.
• Claim 5's procedural posture is reported inconsistently: Ground 3 was instituted on claims 4–6 and 8, but the Federal Circuit's remand order describes claims 3, 5 and 9–15 as having been decided "in view of the '732 patent," and SIPCO's brief describes the Kahn/Burchfiel findings as reaching claims 4, 6 and 8. I cannot reconcile this from the sources retrieved.
• "Greeves" appears in the '780 appellate record as a reference introduced by SIPCO; I could not identify it, and I have not used it.
• The Rule 36 affirmance (Jan. 21, 2021) is carried over from the earlier section; my searches surfaced the remand order and the merits briefs but did not independently re-surface the Rule 36 order.
• I have not verified the full text of claims 2–15 of the '780 (only claim 1 verbatim and the dependent-claim descriptions from the earlier section), so the claim-by-claim table above is directional rather than exhaustive.
