Patent Overview: US 9,971,678 B2

Title: Systems including device and network simulation for mobile application development

Patent number: US9971678B2
Application number: US14/581,475
Filed: 2014-12-23
Granted/Published: 2018-05-15
Priority date (as listed): 2005-06-10
Inventor: Donavan Paul Poulin
Current/Original Assignee: Wapp Tech Corp
Legal status (as listed): Active; adjusted expiration 2027-10-22
Classifications: G06F11/3668, G06F11/3672, G06F11/3688 (software testing/test management); G06F11/3457 (performance evaluation by simulation); G06F30/20 (design optimisation/simulation); G06F17/5009

Purpose and plain-language scope
Based only on the supplied excerpt, the patent concerns systems that combine device and network simulation for developing mobile applications. Its classifications point to software testing and test management and to performance evaluation by simulation. In plain terms, the disclosed subject matter appears directed to tooling that lets developers emulate or simulate mobile device and network conditions while building and testing mobile apps, rather than relying solely on real handsets or live networks. The prior-art keywords listed ("network," "application," "mobile device," "software," "data") are consistent with this reading.

Family/continuation activity noted in the excerpt
The record lists priority links to later US filings including US15/979,330 (US10353811B2), US16/510,928 (US11327875B2), US17/657,213 (US11971812B2), and US18/630,475 (US20240256434A1), plus numerous design-patent filings from 2024–2025. It also records a 2023-11-29 assignment to Wapp Tech Corp. from inventor Donavan Paul Poulin.

What this excerpt does not establish

• No claims, detailed description, or drawings are included, so the actual claimed scope cannot be verified.
• No abstract text or background/field section is present.
• The listed "priority date" of 2005-06-10 is expressly identified as an assumption, not a legal conclusion; the same caveat applies to legal status and expiration.
• Litigation entries appear in the source, but per instructions these are not analysed here.
• No technical details of the simulation approach, architecture, or embodiments can be confirmed from this excerpt.

I'll research litigation involving US Patent 9,971,678. Let me run several searches.

Let me get more detail on the specific cases involving this patent.

I was cut off from additional searches, so the following is based on the records retrieved (Stanford NPE Litigation Database, CourtListener/RECAP, Justia, IP-Navi, and the Google Patents family/litigation listing). Two ground-rule notes up front:

• Date discrepancy: You state today is April 26, 2026, but several retrieved docket records are dated after that (May–August 2026). I report the dates as they appear in the records and flag them.
• I could not fully verify the current status of every case; where I am unsure, I say so.

Summary

US 9,971,678 has been asserted in a substantial campaign by Wapp Tech: ten identified district court matters across E.D. Tex., D. Del., and S.D. Cal. The 2018 "first wave" (Micro Focus/Seattle Spinco, HPE, Wells Fargo, Bank of America) ended in a jury finding of willful infringement against Micro Focus, followed by settlements and dismissals with prejudice in 2021–2022. The 2021 "Second Bank Suits," the 2023 JPMorgan case, and the 2025 Apple/Capital One/Frost case continued the campaign, with the last-case records showing a venue transfer to California in 2026. I could not confirm the final dispositions of the 2021 bank suits (4:21‑cv‑00670 and 4:21‑cv‑00671) or the 2023 JPMorgan case (4:23‑cv‑01137) from the records retrieved.

Caveat: Docket statuses change frequently, and the records here include entries that postdate your stated current date of April 26, 2026 (some dated up to August 2026). Verify current status against PACER/CourtListener for each case number before relying on it.

I'll start by checking the structured PTAB data and then searching for any proceedings on this patent.

Let me dig deeper — I found an ex parte reexamination reference, and I need to confirm whether any AIA trial exists.

Important findings emerging. Let me confirm whether any AIA trial (IPR/PGR/CBM) exists on the '678 specifically, and get the reexam details.

PTAB proceedings overview

Total AIA trial proceedings on US 9,971,678 ("the '678 patent"): 0. Per the structured USPTO ODP block, the ODP returns no inter partes review, post-grant review, or covered business method proceeding for this patent as of the most recent ingest — breakdown: 0 active, 0 claims invalidated, 0 claims sustained, 0 settled, 0 institution denials. That absence is corroborated by the USPTO's own statement in the reexamination file discussed below: "A review of the post grant history for the underlying patent indicates that there have been no other Office post grant challenges made to the patent (Reexamination Proceedings or Inter Partes Review, Post Grant Review, Covered Business Method trials)." (Ex parte reexam 90/016,033, Office Action at 2.)

Bottom line for a defendant: the claims are not PTAB-canceled. No IPR has ever been filed against the '678. The only post-grant challenge on file is an ex parte reexamination of claim 1 (not an AIA trial), requested by Apple and granted in April 2026. So the correct defensive framing is "the patent is intact and IPR-untested — you would have to build the invalidity case yourself," not "claims are dead."

⚠️ Two scope caveats, stated plainly: (1) I was cut off by a tool limit before completing confirmatory searches; the "no AIA trials" conclusion rests on the ODP block plus the USPTO examiner statement. (2) An ex parte reexamination is not an AIA trial and does not belong in the "PTAB proceedings" count — I flag it below because it is the material post-grant event on this patent and a defendant needs it.

Post-grant challenge on file (NOT an AIA trial) — flagged for completeness

Ex Parte Reexamination 90/016,033 — Third-Party Requester: Apple Inc. v. Wapp Tech Corp. (Patent Owner)

• Type: Ex parte reexamination under 35 U.S.C. §§ 301–307 (not IPR/PGR/CBM)
• Filed: 2026-03-06 (request); USPTO granted 2026-04-21
• Status: Granted / reexamination pending. An Office Action was issued (Art Unit 3992) finding a substantial new question of patentability. I do not have a confirmed rejection or an ex parte reexamination certificate on the record I retrieved — do not assume claim 1 has been canceled.
• Panel: N/A — handled by the Central Reexamination Unit. Primary Examiner Joshua D. Campbell, Art Unit 3992. AIA (FITF) status on the form: No (pre-AIA patent).
• Scope / grounds: Claim 1 only. SNQ raised as to claim 1 under 35 U.S.C. § 325(d) analysis; prior art cited by Requester includes the Morrison and Kazman references, supported by declarations of Dr. Ian Cullimore, Mina Ching, Lauren Gluckman, and Shauna Wiest (public-availability and content declarations, all made of record).
• Institution decision (the reexam analog — "Order Granting Request"): Granted 2026-04-21; the USPTO found the cited references raise a substantial new question of patentability as to claim 1.
• Final Written Decision: N/A (reexam ends with an Ex Parte Reexamination Certificate, not an FWD). None located as of this writing.
• Settlement / termination: None. Ex parte reexam is ex parte by design — Apple, as third-party requester, has only a two-month reply window after any Patent Owner Statement (37 C.F.R. § 1.535).
• Appeal: None identified. Reexam prosecution is not appealable to the Federal Circuit by the requester; any adverse Patent Owner appeal would run through the PTAB and then the CAFC.
• Defensive value: This is the lever a defendant has on this patent right now. It targets only claim 1 — the sole independent claim asserted from the '678 — and it was filed by a well-resourced defendant (Apple) with expert declarations. But reexam estoppel does not bind other parties, and no claim has been canceled. Treat claim 1 as "under a cloud," not "dead."

Sibling-patent watch item (NOT on the '678)

IPR2025-01325 (U.S. Pat. No. 8,924,192) is pending at the PTAB and was filed by Capital One (Capital One's authorized Reply to the Patent Owner Preliminary Response notes the petition challenges claim 60, a product-by-process dispute, and Fintiv/§ 314 arguments). The '192 is a sibling in the same family (the '678 incorporates the '192 specification, '678 at 1:8–18), so the panel's construction and validity reasoning may be persuasive — but this IPR cannot cancel any '678 claim, and any § 315(e)(2) estoppel from it attaches only to Capital One and its privies, not to you. I did not find any IPR on the '678 itself. Petition: https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1558251](/patent/1558251)/download-documents

Strategic summary

Claim status of the '678 — CANCELED vs. SUSTAINED vs. UNTESTED. No AIA tribunal has ever reached any claim of this patent, so there are zero canceled claims. Claims 1, 26, 37, and 45 are the independent claims; claim 1 is the one Wapp asserts in litigation, and it is the only claim under reevaluation (ex parte reexam 90/016,033). Claim 1 = challenged-but-alive; claims 26, 37, 45 and all 46 dependents = untested against prior art at the USPTO. Contrast this with the risk you may be facing: the same patent family was tried in district court, where (per Wapp's own amended complaint, ¶ 184) a jury awarded Wapp $172,554,269 — 100% of its damages request — in the Micro Focus/Seattle Spinco matter, and the court granted JMOL on validity. A defendant should assume the '678 will get past a § 101/§ 112 motion and must be attacked with hard prior art.

Estoppel landscape. Because there is no IPR on the '678, § 315(e)(2) estoppel against you is zero — the full universe of § 102/§ 103 art remains available for your own IPR or district-court invalidity case. Two structural limits matter: (a) the '678 is a pre-AIA patent (effective filing date 2005-06-10; the USPTO reexam form marks FITF status "No"), so PGR is unavailable; and (b) CBM review sunset on 2020-09-16, so it is unavailable too. IPR is the only AIA trial avenue left for this patent — and nobody has used it. That is the single most important gap in the record.

Pattern signals. Wapp Tech is an assertion-heavy, single-family plaintiff (E.D. Tex. suits against HP Enterprise, Micro Focus/Seattle Spinco, Wells Fargo, Bank of America, JPMorgan Chase, and now Apple/Capital One/Frost; the JPMorgan case ended in a with-prejudice dismissal with no validity ruling). No defensive aggregator (e.g., Unified Patents) appears anywhere on this patent — the estoppel-inducing, low-cost IPR that NPE defendants usually hope for simply is not there. Apple's 2026 move was ex parte reexamination of all five asserted patents rather than IPRs — a rational choice given the family's short remaining term (the '678 shows an adjusted expiration of 2027-10-22) and reexam's advantages (anyone can file, only patents/printed publications needed, no estoppel, no Fintiv exposure). No Federal Circuit appeal of any PTAB decision on the '678 exists because there is no PTAB decision on the '678 to appeal.

Recommended next steps

• Do not cite "PTAB invalidation" in any defense posture. There is none. Any representation that claims of the '678 have been canceled by the PTAB would be false.
• Track reexam 90/016,033 to its certificate. Claim 1 is the asserted claim; if the CRU cancels it, your infringement exposure collapses. Check the file periodically at USPTO Patent Center / PTAB-E2E and the reexam's prosecution history. The Office Action currently identifies only a substantial new question — that is the beginning, not the end, of the analysis.
• IPR remains fully open — and the clock is running. If you are sued, an IPR petition must be filed within one year of service of the complaint under § 315(b); that deadline is jurisdictional and cannot be excused. Given no estoppel and an un-attacked patent, an IPR is your highest-leverage validity tool. Build the petition on patents and printed publications (the same art class Apple used in the reexam: Morrison, Kazman, and the family's own IDS/reference set), and note that § 325(d) will be a live discretionary risk if you re-pack art already before the CRU.
• Leverage the sibling '192 IPR (IPR2025-01325) for argument, not estoppel. The panel's claim-construction reasoning (especially on the product-by-process theory for the shared "software authoring platform / emulating" language) may transfer to the '678's analogous "software testing interface" limitation — but it will not cancel '678 claims and will not estop Wapp.
• Expect aggressive enforcement. With a $172.5M jury verdict and a JMOL-validity win in the family's history, Wapp has demonstrated willingness to try cases. Budget for a validity fight, and consider whether your exposure warrants a design-around around the "simultaneously visually simulate, via one or more profile display windows, a plurality of operator network characteristics including at least bandwidth availability" core of claim 1.

Verification gap: a final confirmation sweep for any late-2026 IPR on the '678 was cut short; re-run a PTAB-E2E party-name search for "Wapp" before relying on the zero-count for a filing or a § 315(b) deadline.

I'll research the ownership chain before writing. Let me pull the available records.

Let me dig into the assignment records, PTAB activity, and the entity structure.

Ownership & Assignment Reconstruction — US 9,971,678 B2 ("Systems including device and network simulation for mobile application development")

Data-availability caveat, stated up front: I could not pull the actual USPTO Assignment Center (formerly EPAS) record for this patent — the search tooling available to me did not return Assignment Center reel/frame pages, and no reel/frame numbers, correspondents of record, or execution dates surfaced in any indexed source. I will not invent reel/frame numbers. Everything below is drawn from Google Patents legal events for US 9,971,678, the patent's own front matter / cross-reference section, and the litigation record (Justia, CourtListener, RPX Insight, Stanford NPE Litigation Database). Cells I could not verify are marked NOT RETRIEVABLE — verify at Assignment Center.

Inventors

Unusual patterns noted:

• Single-inventor portfolio. A ~51-granted-patent portfolio (per USPTO PatentsView, as reported by PlainPatent) naming one inventor is a structural concentration risk / monetization tell, not by itself an NPE finding.
• No inventor-departure event to observe. There is no "all inventors left the assignee" pattern here because there is only one inventor and he is the assignee's principal. The relevant analogue is the reverse: the inventor did not assign to the company of record until 2023 (see timeline — the recorded assignment of Poulin's interest to Wapp Tech Corp. is dated/recorded 2023-11-29, roughly 17 years after filing and 5 years after the first lawsuit). Late chain-of-title perfection of this kind is a classic pre-assertion housekeeping step.

Original assignee

Wapp Tech Corp. — original assignee on the face of US 9,971,678 and every sibling in the family ("WAPP TECH CORP., Red Deer (CA)" / "Alberta (CA)"; see the cover pages of US 7,813,910, US 8,332,203, US 10,691,579, US 11,327,875).

• Primary line of business: mobile application authoring / test-and-emulation tooling. The '678 specification describes the commercial product line directly — device + operator-network emulation with frame-by-frame resource profiling. The 2018 complaint identifies the practising product category as software testing tools competing with HP LoadRunner / Performance Center / StormRunner / Mobile Center (Korean IP-Navi dispute record for 4:18-cv-00501).
• Did it ship a product embodying the claims? Historically, yes — evidenced, not assumed: the 2018 assertion against Micro Focus/HP targeted LoadRunner-class testing tools, i.e., the plaintiffs sued a direct competitor in their own product market, and Stanford's NPE Litigation Database tags the 4:23-cv-01137 case against JPMorgan with the category "Product company." Whether Wapp ships a practising product today is unverified; Wapp's own 2025 pleading alleges Apple "knowingly engaged in the willful destruction of WAPP's business as a whole… diminished the viability of WAPP's business as a whole" (4:25-cv-00230, Dkt. #1 ¶174) — i.e., the operative business is, on the plaintiff's own account, severely impaired.
• Current status: Operating status not verifiable from public records I could reach. Not in bankruptcy on any record I found; no Chapter 7/11 proceeding surfaced for Wapp Tech Corp. or Wapp Tech Limited Partnership. It remains an active litigant through at least May 2026 (claim construction order, 4:25-cv-00230, signed 2026-05-01, covering the '192, '864, '678, '811 and '579 patents).
• Affiliate as co-plaintiff: suits are brought by Wapp Tech Limited Partnership and Wapp Tech Corp. (Canadian LP + Canadian corporation). I found no recorded assignment transferring the '678 to the LP; the LP appears as a co-plaintiff/co-owner for the family without a corresponding Assignment Center event that I could retrieve. This is the single most important item to confirm at the Assignment Center.

Assignment timeline

Bottom line first: on the record I could retrieve, there is exactly one assignment-type event for US 9,971,678, and it never leaves the founder/assignee orbit.

• 2023-11-29 (execution date not separately shown) / recorded 2023-11-29 — Reel NOT RETRIEVABLE — verify at Assignment Center
  • Conveyance: Assignment of assignors' interest (Google Patents legal event label: "Assigned to WAPP TECH CORP. — reassignment"; docket text: "ASSIGNMENT OF ASSIGNOR INTEREST (SEE DOCUMENT FOR DETAILS)").
  • Assignor: POULIN, DONAVAN PAUL
  • Assignee: WAPP TECH CORP.
  • Correspondent: NOT RETRIEVABLE — verify at Assignment Center. No correspondent of record appeared in any indexed source; I therefore cannot test for a repeat-player recording attorney. (Litigation counsel of record in 2025–26 — Feinberg Day Kramer Alberti Lim Tonkovich & Belloli LLP — is counsel on the briefs, not a recorded assignment correspondent, and appears once in the material I retrieved. A single appearance is not a signal.)
  • Context: Chain-of-title perfection, not a transfer. The inventor confirms/records his assignment to the company that was already the named assignee on the issued patent — 17 years post-filing, 5 years post-first-suit. No consideration, no third party, no change of beneficial control observable.

No other recorded assignments were surfaced for US 9,971,678. Specifically, I found no:

• assignment to any entity containing "IP / Holdings / Licensing / Ventures / LLC";
• security agreement or collateral assignment;
• merger, change-of-name, or release recording;
• assignment to or from Acacia, Marathon, Intellectual Ventures, IPNav, Wi-LAN, Conversant/Mosaid, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation Corp, or any Spangenberg-affiliated entity;
• assignment to RPX, AST, LOT Network, Unified Patents, or OIN.

The Google Patents litigation block for this patent is the family's whole assertion history, and every defendant is a user or maker of accused software, never a patent-holding intermediary:

Family-level: Google Patents flags this patent's family as having litigation and lists a "First worldwide family litigation filed" Darts-IP link (family 42830980). Unified Patents maintains a monitoring page for sibling US 7,813,910 (portal.unifiedpatents.com/patents/patent/US-7813910-B1, assignee "Wapp Tech Corp"), and "Unified Patents, LLC" appears as petitioner in 2022 miscellaneous proceedings in the S.D. Tex. related docketing for Bank of America (5:2022mc80112 / 5:2022mc80114). I could not confirm any IPR or PGR petition against the '678 itself.

NPE / troll-pattern signals

Behavioural observations that do not map cleanly onto the eight chain signals (recorded for completeness, not scored as signals):

• Post-2018 the defendants shift from a direct product competitor (Micro Focus / HP LoadRunner) to licensee-class end users and customers (Wells Fargo, Bank of America, JPMorgan Chase, Capital One, Frost Bank) accused of using Apple's Xcode and Google's Android Studio — the classic "sue the customers of the deep-pocket maker" monetization sequence.
• The 2022, 2023 and (on the pleadings) later rounds all resolved in confidential settlements with dismissal with prejudice, i.e., licensing revenue rather than adjudication.
• Wapp's own pleading concedes the business was badly damaged — so the assertion activity appears to be the principal revenue engine now.

Verdict

NPE — moderate confidence.

The assignment chain itself is not an NPE pattern: the only recorded assignment (2023-11-29, assignor Poulin → assignee Wapp Tech Corp.) never removes the patent from founder control, and none of the structural signals — shell transfer, cascading LLCs, pre-litigation transfer, bankruptcy sale, privateering, defensive-aggregator termination — is present on the record I could retrieve. The call rests on behavioural evidence instead: a single-inventor, founder-controlled Canadian entity with no verified product currently embodying the claims that has, since 2021, asserted the family exclusively against banks and other end users rather than competitors, resolving every round by confidential settlement (BoA and Wells Fargo 2022–23; JPMorgan 2025), plus this patent's indexing in Stanford's NPE Litigation Database with Wapp Tech Corp. listed as a Patent Asserter. That is 2–3 weak signals and no strong signal, which is why the call is moderate and not high. If Wapp can show a currently shipping practising product, this flips to operating-company assertion; if Assignment Center discloses an unreported transfer to a Wapp Tech Limited Partnership or similar vehicle, it flips toward NPE — high confidence.

Three specific things to confirm at the Assignment Center that my sources could not supply: (1) the reel/frame of the 2023-11-29 Poulin→Wapp Tech Corp. recording and its execution date; (2) the correspondent of record on that recording (the key repeat-player test); and (3) whether any separate assignment to Wapp Tech Limited Partnership exists for this patent or its siblings — the LP appears as a co-plaintiff in every suit but no assignment to it surfaced.

I'll search the USPTO database and patent literature for US 9,971,678 and its cited prior art.

Let me dig into the specific patent citation records for US 9,971,678 on FreePatentsOnline and Google Patents bibliographic pages.

I've hit the tool-call limit, so below is my analysis based on the searches that returned before the cutoff. I want to be upfront about one important gap and a few ID cautions before giving the reference-by-reference breakdown.

Scope and integrity notes

(a) What I could and could not retrieve. I could not open the exact USPTO front-page "(56) References Cited" list for US 9,971,678 as filed. Google Patents' full-text page for US9971678B2/en truncates before the citations section, so the list below is reconstructed from three verifiable sources: (i) the ex parte reexamination papers for Control No. 90/016,033, (ii) the reference-cited lists of the '678 patent's own family members, and (iii) the family "Patent Art" listing on Unified Patents. I flag which is which. I do not present any reference as a confirmed front-page citation of '678 unless the source supports it.

(b) A same-number trap I deliberately avoided. One search result was JPS5525788A, whose application number is "JP9971678A" — a 1978 Japanese "Atomizer for liquid fuel." That is not US 9,971,678 and I have excluded it. Under the strict rule I am not auto-correcting anything; I am simply noting the alphanumeric collision so it is not mistaken for relevant prior art.

(c) Statutory posture — read this before the tables. The reexam determination (Paper No. 20260408, Art Unit 3992) raised a substantial new question of patentability only as to claim 1, and it did so on a combination: Morrison in view of Kazman and Linton. A combination theory is a §103 obviousness attack, not §102 anticipation. So the honest bottom line is: on the record I retrieved, no single reference anticipates any claim; the references are asserted as a combination. I say so rather than manufacture clean §102 hits.

(d) Priority-date gate. The reexam gave claim 1 a priority date of June 9, 2006 (the 11/449,958 filing; the June 10, 2005 provisional is not counted for the 20-year term). Any reference dated after June 9, 2006 is not §102 prior art against the '678 claims and can at most be §103 background — I mark these.

1. The prior art the USPTO is actually relying on against '678 (reexam 90/016,033)

These three are, by definition, the most relevant references currently asserted against the patent. All three were found not to have been considered by the original examiner.

§102 assessment: none of these three, standing alone on the retrieved record, is positioned as an anticipatory reference. Morrison–Kazman–Linton is a §103 combination. If you need a §102 theory, it does not exist on this record.

2. Patent references cited in the '678 family (candidate prior art for the shared claim-1 core)

The family's cited-reference lists (FPO page for US 11,886,323; Unified Patents "Patent Art" for US 10,691,579) include the following. These are the references most likely to bear on the network-simulation / device-emulation limitations. Dates are as reported; where the list gave only a priority year I say so.

Note on the applicant's own earlier patents — US 7,543,298, 7,813,910, 8,332,203, 8,924,192, 9,298,864 (all Poulin/Wapp Tech) appear in the family lists. Where the inventive entity overlaps, they are generally not §102 "by another" art against the same invention, but different-subject-matter ones can be §102/§103 art and are worth checking; I did not verify inventorship entity-by-entity here.

3. §102 mapping to the claim structure

The anticipation analysis must target the shared core of independent claims 1, 26, 37, and 45:

a software testing interface that simultaneously visually simulates, via one or more profile display windows, a plurality of operator network characteristics including at least bandwidth availability … based at least in part on bandwidth data predetermined from interactions between one or more mobile devices and at least one operator network.

• The "predetermined … interactions between mobile devices and an operator network" limitation is the crux. The §102-candidate references that plausibly disclose pre-collected real network data driving a simulated bandwidth figure are US 2004/0097237 (NEC, information collecting) and US 7,877,230 (HP, real network response-time data) — but the HP reference is post-2006. Pure device-emulator references (US 2003/0236657; US 2005/0125211) do not clearly reach this bandwidth-data limitation and are better mapped to the dependent simulation-selection claims (2–3, 20, 39).
• Simulated events (SMS/call) — claims 12–13 and 32 → US 2006/0140125 (Ericsson Hybrid Test Bed) is the closest family reference.
• Fee-based network interaction (claims 23–25, 42–44) — I found no prior-art reference in the family lists directed to this; it appears to be a business-method-style limitation with no mapped art.
• Import real-world network profiles (claims 45–49) — closest is US 2004/0097237 and the reexam's Linton reference; no clean anticipatory hit.

4. What I could not verify (stated plainly)

1. The actual front-page citation list of US 9,971,678 — reconstructed, not directly retrieved.
2. Titles/publication venues for Kazman and Morrison — I did not confirm these in a retrieved source.
3. The exact title of Linton, US 2003/0045298 A1 — confirmed as a family-cited reference, but title unverified.
4. Whether any §102 (single-reference) rejection exists — none appears on the retrieved record; the attack is a §103 combination, and only as to claim 1.
5. Precise dates for several family-list references were reported as priority years and should be confirmed against each document's face.

If you want, I can attempt targeted retrieval of the '678 front page (56) list, the Kazman paper, and the Linton '298 publication title in a follow-up pass.

I'll research the prior art references from the reexamination record before building the § 103 analysis.

Let me gather the remaining prior-art references (BlackBerry, Gaertner) and confirm the claim-chart mapping used in the reexam request.

Obviousness Analysis — U.S. Patent No. 9,971,678 B2 under 35 U.S.C. § 103

Building on the prior sections. This analysis takes as given the claim structure set out in the earlier "Independent claims in plain language" section (four independent claims, 1 / 26 / 37 / 45, sharing an identical preamble + core limitation, distinguished only by what "the software is further configured to" do). I do not repeat that content. I also rely on the earlier §4 note that ex parte reexam Control No. 90/016,033 found a substantial new question of patentability (SNQ) as to claim 1 based on Morrison in view of Kazman and Linton. Here I convert that SNQ-level finding into a claim-by-claim § 103 framework.

Caveat. This is a technical/analyst opinion, not a legal opinion or a validity holding. It is written under the PTO's preponderance-of-the-evidence and broadest-reasonable-interpretation (BRI) standards applicable in reexamination, which are more favorable to a challenger than the district court's clear-and-convincing / Phillips standard. It also does not account for claim-construction positions the patent owner may advance (e.g., a narrow reading of "operator network characteristics," "predetermined," or "simultaneously") that could narrow the prior-art field.

1. Legal framework and the level of ordinary skill

• Governing test (Graham v. John Deere, 383 U.S. 1 (1966)): scope/content of the prior art, differences between the prior art and the claims, level of ordinary skill, and secondary considerations.
• KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007): the "teaching, suggestion, or motivation to combine" need not be explicit in the references. Obviousness can be established where a POSITA would have recognized that the combination was predictable, where there was a design need or market pressure, or where the combination uses known elements for their known functions.
• MPEP § 2143 rationales relied on below: (A) known elements, known function; (C) use of a known technique to improve a similar device in the same way; (F) design incentives / market forces; (G) predictable variation.

POSITA (my construct, not from the record): a software engineer with a bachelor's degree in computer science or electrical engineering and ~2–3 years' experience in mobile application development and/or mobile device/network emulation tooling, familiar with J2ME/Flash-style emulators, resource profiling, and wireless network simulation. This person would be aware of both the device-emulation literature (Morrison) and the network/QoS simulation literature (Kazman, Linton).

Priority/prior-art status (flag): The '678 claims a June 10, 2005 provisional priority (provisional 60/689,101). Kazman (June 2003) and Linton (published Mar. 6, 2003) squarely predate that date. Morrison (Sams, ©2005) is the date-sensitive reference — the reexam request buttressed it with the Ching and Wiest declarations on public availability, which is exactly the kind of showing needed to establish that Morrison was publicly accessible before the 2005 priority date. If a POSITA-facing trial court were to find Morrison's public availability post-dates the provisional's priority date, the Morrison-dependent grounds weaken (though Kazman + Linton + BlackBerry could carry several limitations). I could not independently verify Morrison's exact first-public-availability date from the sources retrieved.

2. The prior-art references and what each teaches

3. Claim-by-claim mapping (independent claims)

3.1 Claim 1 — the base system

Assessment: Claim 1 is the strongest candidate for a § 103 rejection — the reexam itself found the Morrison + Kazman + Linton combination raises an SNQ, and (as the earlier section flagged) Linton is the only reference that squarely supplies "bandwidth data predetermined from … interaction[s] … with … a[] operator network." The mapping hinges on (i) reading "operator network" broadly enough to cover the carrier radio environment that Linton's drive tests measure, and (ii) reading "simultaneously visually simulate" broadly enough to cover Kazman's GUI. Both readings are defensible under BRI.

3.2 Claim 26 — base + display performance data

Adds only: "the software is further configured to display data of either application performance, or network performance, or both."

• Kazman displays simulation outputs of system performance (battery, utility, resource consumption) in a GUI; Morrison displays memory/CPU performance of the running MIDlet; Linton measures packet flow to "estimate the usability of the application." Because claim 26 is in the alternative ("either… or… or both"), a single reference displaying application performance suffices. Claim 26 is at least as obvious as claim 1, and arguably more so.

3.3 Claim 37 — base + "interact with a network"

Adds: "the software is further configured to interact with a network."

• Linton's simulation machine is a networked appliance that services clients over a network connection and interacts with a server; Kazman and the BlackBerry Simulator interact with simulated network conditions. Under BRI, "interact with a network" is broad. Claim 37 is at least as obvious as claim 1.

3.4 Claim 45 — base + import real-world mobile network profiles

Adds: "interaction with a network enables the software to import real-world mobile network profiles."

• Linton is the near-textual hit: its whole premise is capturing real-world QoS statistics (drive-test measurements of throughput, delay, bit-error) and importing/using them to condition the simulation. Claim 45 is arguably the most directly anticipated/obvious of the four independents on this limitation, though it retains the same base limitations as claim 1.

Independent-claim summary: all four share the same base, so the claim-1 analysis controls. Claims 26/37/45 add limitations that, if anything, increase the prior-art overlap (Kazman/Linton/Morrison all display performance data; Linton and the BlackBerry simulator both involve network interaction and real-world profile import).

4. Dependent claims

5. Motivation to combine (the KSR/§ 103 rationale)

A POSITA would have combined these references for several independent and mutually reinforcing reasons:

1. Same field, same problem, same solution type. All three primary references address the identical practical problem: predicting how mobile software will behave on real hardware without repeatedly deploying to real handsets. Morrison explicitly frames the J2ME emulator as avoiding "download[ing] and run[ning] them on a physical mobile device" (p. 52); Kazman frames the test-bed as exploring architectural choices "before building the actual device itself." A POSITA improving a device emulator would look to the network-simulation literature — and vice versa.
2. Known technique to improve a similar device in the same way (MPEP 2143(C)). Linton's contribution is not a new test platform but an impairment/QoS mechanism that can be dropped into any application simulator: "the QoS statistics generated… are then used… to operate on a data flow generated by any application to be evaluated." Using Linton's real-world-measured QoS data inside Kazman's environment layer (or Morrison's emulator) is precisely the "arrangement of old elements" KSR makes unpatentable.
3. Direct design incentive — the realism gap. A device emulator alone tells a developer only how software behaves under assumed network conditions. Kazman states the design premise: mobile devices "must endure widely varying network connectivity and quality of service conditions," and its environment layer uses modeled bandwidth. A POSITA seeking to test rather than model would be motivated to substitute measured bandwidth/QoS data (Linton) so results reflect reality — the very "predetermined… bandwidth data" of claim 1. This is a motivation with a predictable result, KSR's core case.
4. Market pressure (MPEP 2143(F)). The '678 specification itself describes intense carrier/model churn ("a new handset model being launched every other day") and the need for realistic, world-wide testing — the same pressures that make combining device emulation with real-world network profiles the obvious commercial step.
5. Reasonable expectation of success. Morrison and Kazman are software simulators; Linton's QoS impairment is a software module ("a single software program running on a processor"). There is no technological incompatibility and no unpredictability; combination is a matter of software integration.

Combination ladder (per the reexam's own framing):

• Primary ground: Morrison + Kazman + Linton → claim 1 (and claims 26/37/45).
• Alternate/supplemental: Morrison + Kazman + BlackBerry (network simulation supplement) for the network-simulation limitations; + Gaertner for "simultaneously… display [of] multiple different resources."
• Each ladder adds only dependent-claim niceties for claims 2–50.

6. Anticipated patent-owner rebuttals and how they fare

7. Bottom line and confidence

• Claim 1 (and thus the base of claims 26, 37, 45): Likely obvious over Morrison in view of Kazman and Linton — consistent with the reexam's SNQ finding. The pivotal limitation ("bandwidth data predetermined from interactions between mobile devices and an operator network") is met most directly by Linton, with Kazman supplying "simultaneously…simulate…bandwidth availability…indicative of performance when executing the application," and Morrison supplying the mobile-emulator testing interface and simultaneous monitoring windows. Moderate-to-high confidence, subject to the Morrison prior-date issue and to claim-construction positions.
• Claims 26, 37, 45: At least as obvious as claim 1; each added limitation is met even more directly (Kazman/Linton performance displays; Linton's networked simulator; Linton's real-world "real-world mobile network profiles").
• Claims 12–13 (SMS / incoming call), 8–11 (real-world connection statistics), 46–50 (import real-world profiles): High-confidence obviousness via Kazman and Linton, respectively.
• Claims 15–20, 23–25, 38–44 (geography, UI selection, fees): Weaker on the technical references alone, but these are the least technical limitations; fee/geography claims also raise § 101 questions and rest partly on the patent's own admissions.
• Claim 50: scope indeterminate from the retrieved text (truncated mid-sentence); do not opine until the full claim text is confirmed.

Explicit uncertainties: (1) Morrison's exact public-availability date relative to June 10, 2005; (2) whether "operator network" will be construed to cover Linton's measured radio environment; (3) whether "simultaneously visually simulate… via one or more profile display windows" imports a requirement not met by Kazman's Fig. 3 GUI; (4) the SNQ is not a merits rejection — the examiner's second-stage Office action (which the July 14, 2026 notice-of-filing-date and the paper trail indicate is pending) will apply the actual § 103 analysis and give the patent owner a chance to rebut.
