US 9746341

I'll run targeted searches for this exact patent number and its litigation/docket footprint.

Let me dig into the claims text and the specific litigation docket.

Let me pin down the full independent claim language and check for any Federal Circuit or PTAB activity.

US 9,746,341 B2 — verification summary

Search performed: USPTO/Google Patents full text of the patent, Justia patent copy (claim text), uspto.report, and federal docket sources (CourtListener/RECAP, PACER Monitor, Justia Dockets, RPX Insight) for the litigation tied to this patent. No Federal Circuit 2026 docket for US 9,746,341 was located in my searches — see the uncertainty note at the end.

Bibliographic data (as listed)

Continuation chain (from the patent's own cross-reference section): 15/435,283 is a continuation of 14/997,521 (filed 2016‑01‑16) → continuation of 14/067,415 (now US 9,354,069) → continuation of 13/346,265 (now US 8,577,390) → continuation of 12/929,458 (now US 8,095,152) → continuation of 12/484,091 (now US 7,881,730) → division of 10/410,740 (now US 7,565,155), filed 2003‑04‑10 → provisional 60/371,941 (2002‑04‑10).

Abstract (verbatim)

"The preferred embodiments of the present invention are directed to methods and systems for dynamic route estimation and prediction using discrete sampled location updates from various mobile devices for the purpose of providing a graphical representation of a mobile device's route along a known network path of map data. The embodiments also provide supplemental route metrics, such as traveled distance, elapsed time, etc., and the capability to assign destination points for the purpose of providing the ability to modify location update points in an application, such as a route planner, and/or to store the dynamically generated route based on various preferences for later retrieval."

Plain-language overview of the independent claims

The patent has three independent claims — claim 1 (apparatus), claim 6 (non-transitory computer-readable medium), and claim 11 (method) — with dependent claims 2–5, 7–10, and 12–14. All three independents cover the same core invention from different statutory categories.

Claim 1 — Mobile computing apparatus. A mobile device (GPS receiver; memory storing map data; display; at least one processor; a non-transitory computer-readable medium with instructions) that:

• receives discrete position updates individually and, on the first update, shows the device's first position on a map built from the map data;
• before the second update arrives, predicts and displays a second position based on the first update plus metrics (at least one of speed, heading, road speed limit, turn restriction), and displays a partial route from the first position to that predicted second position — i.e., it fills the gap between GPS fixes rather than drawing straight "breadcrumb" lines;
• when the second update does arrive and its location does not coincide with the predicted second position, updates the display of the predicted position and the partial route; the updated partial route corresponds to the time interval between the first and second updates.

Claim 6 — Non-transitory computer-readable medium. The same functionality expressed as instructions stored on a CRM for use with a mobile computing apparatus that this time expressly includes a GPS receiver, a wireless modem, memory storing map data, display, and at least one processor controlling those elements; the instructions cause the same receive → predict/display partial route → correct-on-next-update behavior.

Claim 11 — Method of controlling a mobile computing apparatus to dynamically predict and display a route of travel, in a device having a GPS receiver, map-data memory, display, and at least one processor. The method begins with "providing the mobile computing apparatus with the map data" and then performs the same predict-between-fixes and correct-on-arrival sequence.

Dependent claims (verified in part): claims 2/7/12 — position updates come from the GPS receiver and are based on GPS position signals; claims 3/8/(and a method counterpart) — updates are received periodically; claims 4/9/13 — the map data is transmitted to the mobile device from at least one server over a wireless network; claims 5/10 — display an indication of a destination location, display plural possible routes to that destination based on the metrics, display the metrics, and update the metrics display as the device travels toward the destination.

Litigation / docket footprint

• Bluestone Ventures, Inc. v. Google LLC, No. 7:25-cv-00569 (W.D. Tex., filed Dec. 12, 2025) — this is the case flagged on the patent's Google Patents page. Judge David Counts, referred to Magistrate Judge Derek T. Gilliland; cause of action 35 U.S.C. § 100/patent infringement, jury demanded; plaintiff's counsel of record Raymond W. Mort, III.
  • Per the complaint analysis, the accused functionality is Google Maps (route computation on digital map data, predicting device position between GPS updates, multiple route alternatives with travel times, removing untaken routes, route preferences, and sharing real-time route to a second device) running on Google Pixel phones for the apparatus claim.
  • Docket activity through April 2026 includes: answer filed ~Mar. 27–30, 2026; Rule 26(f) discovery report/case management plan Apr. 13, 2026; scheduling order Apr. 22, 2026; a sealed motion Apr. 24, 2026.
• A related, earlier family action asserted by the same plaintiff — Bluestone Ventures Inc. v. Uber Technologies, Inc., No. 6:21-cv-00685 (W.D. Tex., Waco) — asserted US 9,921,077 and US 10,502,583, both siblings in this same continuation family (they appear on the '341 patent's "Priority to" listing).
• Note: one search hit (a court filing PDF) discusses validity of "claims 2, 6, and 10 of the '337 Patent" alongside the '341 patent. That appears to refer to a different, sibling patent ending in '337 (e.g., US 10,274,337, which shares this priority chain); I could not confirm which '337 patent it is, so treat that reference as unverified.

Uncertainty and caveats

1. Federal Circuit: I found no CAFC 2026 appeal docket involving US 9,746,341. My searches could not reach a CAFC-specific docket system directly, so this is "not found," not "confirmed absent."
2. Claim text completeness: Claim 1 is quoted essentially in full. Claims 6 and 11 were retrieved only in truncated form from the Justia copy (the search result cut off mid-claim), so the summaries of claims 6 and 11 above paraphrase the verified preamble and element structure rather than reproducing every limitation. I also cannot confirm from the retrieved text whether the claim set ends at claim 14 or continues; the verified dependents are 2–5, 7–10, and 12–14.
3. Legal status: "Expired – Fee Related" and the 2023‑04‑10 anticipated expiration are Google Patents' automated assumptions (Google expressly disclaims that these are legal conclusions). Given that date, a suit filed in December 2025 would necessarily concern pre-expiration infringement; I have not verified the actual expiration/fee history or any damages theory from an authoritative USPTO source.
4. Identifiers were interpreted literally as given: patent 9746341 / US 9,746,341 B2, application 15/435,283, case 7:25-cv-00569.

I'll search for litigation involving US patent 9746341 across multiple sources.

Let me search for the specific case referenced on the patent page and related litigation by the assignee.

I found a key case. Let me dig deeper into whether the '341 patent was asserted in other cases (including the Uber case) and confirm the Google case details.

Litigation involving U.S. Patent No. 9,746,341 ("'341 patent")

Based on my searches (Google Patents, CourtListener/RECAP, PACERMonitor, Dockets.Justia, RPX Insight, Justia, and Unified Patents), here is what I can confirm — and, importantly, what I cannot.

1. Confirmed case: Bluestone Ventures, Inc. v. Google LLC

Alleged infringing functionality (from the complaint analysis): computing routes between locations using digital map data (rather than merely plotting GPS points); predicting a device's position between GPS/position updates using metrics such as speed, heading, road speed limit, and turn restrictions; displaying multiple route alternatives with travel times; dynamically removing outdated/untaken routes; user-preference-based routing; and transmitting a user's real-time route to a second device for remote tracking. For the '341 patent the analysis maps allegations to independent claim 11 (e.g., predicting a second position and displaying a partial route).

Recent docket activity (from CourtListener/RECAP): The docket reflects an Answer to Complaint (around Mar. 30, 2026), a Rule 26(f) discovery report / case management plan (Apr. 13, 2026), a Scheduling Order (Apr. 22, 2026), a "Transfer Case" entry (Apr. 23, 2026), and a Sealed Motion (Apr. 24, 2026). I could not confirm the substance or outcome of the "Transfer Case" entry from the sources available, so I flag it as an item to verify on PACER — it may indicate a change of venue/division or a transfer, but I cannot state that with confidence.

This case is also the litigation the Google Patents page for US9746341B2 links to (family litigation, Texas Western District Court, 7:25-cv-00569).

2. Related case — patent asserted? NOT confirmed

Bluestone Ventures Inc v. Uber Technologies Inc, No. 6:21-cv-00685, W.D. Tex. (Judge Alan D. Albright), filed June 28/29, 2021; listed by Unified Patents as closed, with a termination date of 2021-09-26. Reporting describes Bluestone asserting two patents directed to displaying transportation-provider locations on a map, determining a customer's pickup location via mobile device, and selecting a "preferred" transportation provider based on variables such as passenger capacity or ETA.

I could not confirm that the '341 patent itself was one of the patents asserted in the Uber case. The subject matter described (transportation-provider matching/dispatch) is consistent with certain embodiments of the '341 family (e.g., the dispatch/ranking FIGS. 25–26 in the '341 specification), but that is a plausible inference, not a verified fact. Do not treat this as a confirmed assertion of the '341 patent without checking the Uber complaint's asserted patents.

3. Other family litigation

The patent's Google Patents page also displays a "First worldwide family litigation filed" link pointing to the Darts-ip family record (family ID 34395939). I was not able to retrieve the underlying case details within my search budget, so I cannot name that case or its parties.

Bottom line

• The one litigation I can confirm asserting U.S. 9,746,341 is: Bluestone Ventures, Inc. v. Google LLC, No. 7:25-cv-00569 (W.D. Tex.), filed December 12, 2025 — currently pending.
• The earlier Bluestone v. Uber case (6:21-cv-00685) belongs to the same plaintiff's campaign and may or may not have asserted the '341 patent; I could not verify that it did.
• I found no other confirmed litigation (no CAFC appeal, no other district-court case) specifically identifying U.S. 9,746,341.

Caveats and recommended verification

1. My searches did not include a direct, filtered pull from the Unified Patents caselist for this patent number before I reached my search-step limit, so a comprehensive assertion history across all cases is not guaranteed.
2. PACER is the authoritative source for the current status of 7:25-cv-00569 (especially the "Transfer Case" and sealed-motion entries).
3. I am not auto-correcting any identifiers; all patent and case numbers above are reported literally as found.

Would you like me to attempt to pull the Unified Patents caselist filtered to this patent and the Uber complaint's asserted-patent list (each would require a fresh search)?

PTAB / AIA Trial Proceedings — US 9,746,341 ("Method and system for dynamic estimation and predictive route generation," BlueStone Ventures Inc., priority 2002‑04‑10)

Proceedings overview

Zero AIA trial proceedings are on file for US 9,746,341. The structured "PTAB proceedings on file" block (USPTO Open Data Portal, canonical list) returns no IPR, PGR, or CBM naming this patent as the challenged patent, and my independent web searches surfaced no petition, institution decision, or Final Written Decision directed at the '341 patent. The bottom‑line defensive posture for a defendant is therefore not "the patent has survived IPRs and is hardened" and not "claims are canceled — the troll has no case." It is: the PTAB docket is clean, but the patent itself is expired (anticipated expiration 2023‑04‑10), which is a broader and cheaper defense than any IPR outcome — any asserted claim can only support a damages theory for pre‑expiration conduct, so a defendant's first move is a term/expiration check, not a PTAB filing.

No proceedings to report

Because the count is zero, there are no proceeding entries (no IPR20xx‑xxxxx, no petitioner, no panel, no FWD) to enumerate. I will not invent proceeding numbers or outcomes. For the record, what the searches did turn up, and why none of it is a proceeding against the '341:

• Sheha references appearing in PTAB papers are prior art, not challenged patents. Numerous PTAB documents cite "Sheha" (e.g., U.S. Pat. 7,333,820 and U.S. Pat. App. 2004/0054428) as an obviousness reference against other patents (e.g., Blitzsafe '055 IPRs, Apple IPR2023‑00115 re 11,234,117). Being a cited reference is not a proceeding on the '341.
• Related‑family litigation, not PTAB, is the live event. Bluestone Ventures, Inc. v. Google LLC, No. 7:25‑cv‑00569 (W.D. Tex.), complaint filed 2025‑12‑12, assigned to Judge David Counts, referred to Magistrate Judge Derek T. Gilliland. Complaint analysis indicates BlueStone asserts the '341 patent (independent claim 11 pleaded) alongside a sibling patent, the "'337," against Google Maps. Source: https://www.courtlistener.com/docket/72028521/bluestone-ventures-inc-v-google-llc/ . That is an infringement action, not an AIA trial.
• No reexamination or other post‑grant review of the '341 was surfaced either.

Strategic summary

Claim status of the '341 (canceled / sustained / untested). Because no IPR/PGR ever reached the merits, no claim of the '341 has been canceled, and no claim has been sustained in a Final Written Decision — every claim is, in PTAB terms, untested. That cuts both ways: there is no estoppel‑bearing FWD to exploit, but there is also no PTAB‑blessed validity finding for the patent owner to brandish. The one claim I can identify from grounded sources as asserted in litigation is independent claim 11 (and its dependents) against Google; the rest of the claim set has not been adjudicated anywhere. Sources: complaint analysis for 7:25‑cv‑00569; patent text at https://patents.google.com/patent/US9746341/en .

The controlling fact is expiration, not validity. The '341 traces to non‑provisional U.S. App. Ser. No. 10/410,740 (filed 2003‑04‑10) and a provisional (2002‑04‑10). Google Patents records an anticipated expiration of 2023‑04‑10, and the record status reads "Expired." An expired patent can still be IPR'd (the Board uses Phillips claim construction for expired claims), but expiration usually makes IPR economically pointless for the defendant — you cannot infringe an expired claim going forward, so the exposure is a lookback damages window and nothing more. This is the highest‑value § 1 point in any defense memo on this patent, and it should be run before anyone budgets six figures for a petition.

Estoppel landscape. With no instituted AIA trial, no § 315(e)(2) estoppel has attached to anyone. Any prior‑art ground — § 102 or § 103, patents and printed publications — remains fully available to a defendant, subject to the ordinary § 315(b) one‑year clock and the current discretionary‑denial regime. Note the clock is real here: service on Google appears to have occurred by 2026‑01‑26 ("Summons Returned Executed," 7:25‑cv‑00569), which would put a § 315(b) bar date in roughly late January 2027 for Google or a privy. Independent/third‑party petitioners (e.g., a defensive aggregator) are not bound by that clock.

Pattern signals. The patent owner (BlueStone Ventures, successor to the Sheha / Networks‑In‑Motion line) has pursued an aggressive continuation strategy — a long chain of siblings and continuations, including US 9,921,077; 10,274,337; 10,502,583; 10,551,208; 10,677,608; 10,996,071; 11,346,684; 11,473,925; and 11,619,513 — several of which issue with the same 2002/2003 priority and therefore share the 2023‑04‑10 term. That pattern (narrow continuations issuing late, then asserted) is a classic late‑life NPE assert‑and‑settle posture. There is no evidence of a defensive‑aggregator (e.g., Unified Patents) IPR in the chain, and no PTAB appeal history for the '341.

Recommended next steps

• Lead with expiration, not PTAB. Pull the '341's front page and PTA/terminal‑disclaimer history and confirm the 2023‑04‑10 expiration and any maintenance‑fee lapse. If confirmed, scope the case to the pre‑expiration lookback period; a defendant's leverage here comes from a finite, past‑dated damages window rather than from invalidating claims.
• No FWD exists to link or quote. There is no PTAB decision to cite because no trial was instituted. Do not assert that any claim is "canceled" — the structured ODP data and public search both show the contrary (nothing on file). Verify independently at PTAB E2E / PTAB Center before filing anything that relies on the absence: https://ptab.uspto.gov (PTAB E2E) and the ODP patent page.
• Calendar the § 315(b) bar. If Google (or a privy) wants an IPR, the one‑year window from ~2026‑01‑26 service closes in roughly January 2027. Given the USPTO's 2025 discretionary‑institution posture (Magnolia Medical line; Director‑controlled institution under the October 2025 Squires memorandum), even a merits‑strong petition faces a materially reduced institution rate — factor that into whether a petition is worth filing at all on an expired patent.
• Run a family‑wide PTAB sweep. The '341's term‑sharing siblings ('337, '077, '337, etc.) are the more likely targets in the current Google campaign; check each for existing IPRs, reexams, and FWDs before committing to a forum strategy, because a family‑wide picture may reveal proceedings the single‑patent ODP view does not.

Confidence note: I am confident in the absence of PTAB proceedings on the '341 based on the canonical ODP block plus search. I am not able to certify a negative for every related‑family patent, and my searches were truncated by a step limit, so treat the "no reexamination / no aggregator IPR" statements as "not found" rather than exhaustively verified. No proceeding numbers, panels, or claim outcomes have been fabricated; where I lack data, I have said so.

I'll research the assignment chain for US 9746341 before reconstructing the record.

Let me try to access the citation lists directly from different sources.

Prior Art Analysis for U.S. Patent No. 9,746,341 — Retrieval Status and Framework

Important upfront disclosure: My searches did not return the authoritative "References Cited" (front-page citation) list for US 9,746,341 B2. Rather than populate the requested table with invented numbers, I am reporting exactly what I retrieved, what I could not retrieve, and a rigorously-scoped analysis of what the citation record must contain and how each category maps to § 102. I flag every place a number needs verification against the file wrapper. Per the operating rules, I am not auto-correcting any identifier.

1. Target patent — literal identification

Search results did not surface any similarly-numbered patent masquerading as this one; the only authoritative record returned was the Google Patents page above.

2. What my searches actually returned (and why the citation list is missing)

My tool queries hit the search-step limit before I could pull the "Citations" tab directly. The results I did get were largely irrelevant false positives — documents that merely contain the phrase "References Cited," not citations to the '341 patent. To prevent the analysis from being polluted, I am explicitly excluding these:

• WO 2015/168126 A1 search report (PCT/US2015/027997) — its cited art (US 2009/0151925 Richards; US 2011/0094742 Badalamenti; US 2003/0111224 Halley; US 2009/0008078 Patel; US 6371210 Bode) relates to downhole/well-screen subject matter, not navigation. Not applicable to the '341 patent.
• WO 2016/112452 A1 (window covering; Biber, Souder art) — unrelated.
• EP 3 255 376 A1, US 8,764,326, WO 2024/128741 A1 (barcode scanners) — unrelated.
• WO 2013/137357 A1, WO 2020/172395 A1, WO 2018/052691 A1, JP 2022-549199 A, PCT/US2015/041562 / 1507855 — unrelated mechanical/electrical search reports.

The one relevant family hit was the parent patent page: US 7,565,155 B2 (application 10/410,740) — see https://patents.google.com/patent/US7565155. Its citation list is the best available proxy for the '341's, but I was not able to extract the actual reference numbers before hitting my search limit.

Bottom line: I cannot honestly enumerate the individual patent citations of US 9,746,341 from the evidence I retrieved. Any table of specific reference numbers at this point would be fabrication.

3. Why the citation list matters — and where it comes from

The '341 patent is a straight continuation with a 15-year chain. Per its own CROSS-REFERENCE paragraph (authoritative, quoted from the specification):

"This application is a continuation of U.S. patent application Ser. No. 14/997,521 … filed on Jan. 16, 2016; which is a continuation of … Ser. No. 14/067,415 … filed on Oct. 30, 2013, now U.S. Pat. No. 9,354,069; which is a continuation of … Ser. No. 13/346,265 … filed on Jan. 9, 2012, now U.S. Pat. No. 8,577,390; which is a continuation of … Ser. No. 12/929,458 … filed Jan. 26, 2011, now U.S. Pat. No. 8,095,152; which in turn is a continuation of … Ser. No. 12/484,091 … filed Jun. 12, 2009, now U.S. Pat. No. 7,881,730; which is a division of … Ser. No. 10/410,740 … filed Apr. 10, 2003, now U.S. Pat. No. 7,565,155; which claims priority from U.S. provisional patent application No. 60/371,941 filed Apr. 10, 2002…"

Analytical consequences for § 102:

1. Critical date = April 10, 2002 (provisional) / April 10, 2003 (first non-provisional). Because the effective filing date precedes March 16, 2013, the pre-AIA § 102 regime governs, provided the priority chain is valid and the specification provides § 112 support for the claims.
2. The most dangerous art is therefore patents and printed publications dated before April 10, 2002 — this is § 102(b) art and cannot be sworn behind. Publications between April 10, 2002 and April 10, 2003 can only be § 102(a)/§ 102(e) art and may be antedated by a proper § 1.131 declaration.
3. The § 112 priority question is the real vulnerability. A continuation filed in 2017 cannot claim 2002 as its effective date for subject matter not disclosed in the 2003 parent. If the accused functionality (e.g., the real-time predictive-position elements mapped to claim 11) is not supported by the 10/410,740 disclosure, the effective date shifts forward and AIA § 102 art (including the 2011–2016 references the examiner would more naturally cite) becomes available. This is precisely the kind of priority attack a defendant like Google would raise. I cannot resolve it without the claim chart and the parent's disclosure.

4. Claim architecture available for § 102 mapping

I do not have the verified full claim text. What is available from the records I retrieved:

• The Google Patents "prior art keywords" for the '341 are "mobile computing apparatus," "display," "route," "updates" — indicating the independent claims are apparatus/method claims couched in terms of a mobile computing apparatus, a display, route generation, and location updates.
• The earlier (previously generated) litigation analysis — which I am building on rather than repeating — maps the Google complaint's § 102/§ 271 allegations for the '341 to independent claim 11, involving predicting a second position and displaying a partial (predicted) route. I did not independently verify claim 11's text, so treat the claim-number mapping as complaint-derived, not claim-text-derived.

Because I cannot quote the claims verbatim, the § 102 element-by-element mapping below is stated by claim element/category, not by re-drafted claim language.

5. The prior-art landscape the citation record must address (candidate categories — not confirmed citations)

The specification itself concedes a dense pre-2002 art field. It names, as known prior art: AVL, LBS, Fleet Tracking Systems, GIS, breadcrumb trails, GPS+wireless MODEM telemetry, and the positioning technologies E-OTD, TOA, AOA, gpsOne (Qualcomm), SnapTrack, and Assisted-GPS. Each is an admission that predates the invention. A thorough § 102 analysis of the '341 must draw on the following categories. I give categories and named systems rather than inventing reference numbers:

§ 102 conclusion for the package: Categories C, D, E, and F are the strongest § 102(b) challenges to the independent claims' preamble/environmental elements, because the specification itself admits them as prior art. The genuinely novel core — and the only place a § 102 reference must land to anticipate — is the combination: generating, in real-time, an estimated routable path between two discrete location samples using a routable map network + preferences, and the associated predictive interval-fill (claim 11). No single pre-2002 reference is likely to anticipate the full combination; the realistic attack is § 103 (obviousness) over AVL/map-matching + route-guidance, not § 102 anticipation. I state this as a probability, not a certainty, because I have not seen the examiner's references.

6. Where to obtain the actual citation list (verification plan)

Because the authoritative record was not retrievable in my budget, the following are the sources that will yield the exact "References Cited." I recommend pulling each:

1. USPTO Patent Public Search / PatentCenter — application 15/435,283, "References Cited" and "Notice of References Cited (PTO-892)" in the file wrapper. This is the only authoritative list. (Note: continuations filed in 2017 sometimes carry few or no new examiner citations, inheriting the parent's record — so also pull the parent's file wrapper.)
2. Google Patents "Citations" tab for US 9,746,341 B2 (patent citations + NPL + "Similar Documents"), at https://patents.google.com/patent/[US9746341B2](/patent/US9746341B2)/en.
3. Parent patent record US 7,565,155 B2 — https://patents.google.com/patent/US7565155 — for the original 2003-era examiner art, which is where the substantive pre-2002 references will be.
4. FreePatentsOnline / Espacenet INPADOC for the same front-page "(56) References Cited."
5. The family's litigation record — Bluestone Ventures, Inc. v. Google LLC, No. 7:25-cv-00569 (W.D. Tex.), docketed via https://portal.unifiedpatents.com/litigation/Texas%20Western%20District%20Court/case/7%3A25-cv-00569 — for the invalidity contentions (which will list the art Google actually asserts).

7. Caveats and explicit non-answers

• I did not retrieve, and therefore do not report, the specific patent citations of US 9,746,341. Any numbered list I produced would be fabricated. This is the honest status.
• The two searches I ran for the citation list returned irrelevant search reports (downhole tools, window coverings, barcode scanners) that merely contained the string "References Cited." I excluded them and named them so they are not mistaken for '341 art.
• I could not verify the verbatim text of claim 11; the "predicting a second position / displaying a partial route" characterization is carried over from the earlier litigation section and is complaint-derived.
• The § 112 priority question and the resulting pre-AIA-vs-AIA framework choice are flagged as unresolved and are likely dispositive of which references even count as prior art.
• Consistent with the earlier section, no identifier has been auto-corrected; all numbers are reproduced literally.

Recommended next step: authorize a fresh, targeted retrieval pass (PatentCenter application 15/435,283 + the parent 7,565,155 file wrapper, and the Google Patents Citations tab). With those two PDFs I can complete the requested per-reference table (full citation, date, description, § 102 claim mapping) against the verified claims.

I'll research the prior art relevant to this patent's claims and priority date before constructing the obviousness analysis.

I have useful leads. Let me pull the actual "References Cited" lists and key prior-art references for the '341 family.

Obviousness Analysis — U.S. Patent No. 9,746,341 ("'341 patent")

Threshold note on inputs (flagged contradiction). The task instructs me to "use the results from the Prior Art section of this page," but the previously-generated sections provided to me contain only the Litigation summary and a partial Assignment history — no Prior Art section was supplied. I therefore cannot "build on" a prior-art section that is absent. Rather than fabricate its contents, I reconstruct the obviousness analysis from (a) the patent's own specification (authoritative text supplied), (b) the family's claim language and prosecution-visible references, and (c) generally known pre-2002 art. Every reference I could not independently verify in this pass is labeled as such. This gap should be closed before the analysis is relied upon.

1. Legal framework

• Priority date: April 10, 2002 (provisional 60/371,941). The application (Ser. No. 15/435,283, filed Feb. 16, 2017) is a continuation of a chain going back to Ser. No. 10/410,740 (filed Apr. 10, 2003, now U.S. 7,565,155).
• Because the effective filing date predates March 16, 2013, and assuming the claims are entitled to the 2002 priority (a continuation cannot add matter), pre-AIA 35 U.S.C. § 103(a) governs. Prior art is defined by pre-AIA §§ 102(a), (b), (e), (f), and (g).
• The obviousness inquiry follows Graham v. John Deere (scope/content of claims; scope/content of prior art; differences; secondary considerations) and KSR Int'l v. Teleflex (a combination is obvious where there is an articulated reason with a rational underpinning; predictable results; finite number of identified solutions; design incentives).
• POSITA: a person with a B.S. in CS/EE or equivalent and ~2–3 years' experience in GPS, digital mapping, navigation, and/or automatic vehicle location (AVL) systems. This is the field the patent itself describes.

2. Claim scope (the concepts to be evaluated)

The '341 claims are continuation claims mirroring the family (independent claims in the '155 parent include a "method of providing predictive position information" for a mobile device, a computer-readable medium counterpart, and a multi-device method). Per the litigation summary, the asserted independent claim is claim 11, directed to predicting a second position and displaying a partial route. The recurring limitations across the family are:

Critical observation: The spec's own Background is an admission of prior art ("Applicant Admitted Prior Art," AAPA). It concedes that mapping software, GPS, real-time wireless data transfer, AVL/LBS/fleet tracking, breadcrumb trails, and "true routing" over a network of paths were all "well known to people skilled in the art." These admissions alone supply much of L1, L2, and the general environment, and they defeat any argument that the inventions resided in those elements.

3. Prior-art references (grouped)

Source-A grounded references (verified in this research pass):

• Dillenburg et al., "The Intelligent Travel Assistant," Mar. 15, 2002, pp. 1–7 — a non-patent reference that appears in the family's record (Justia, U.S. 9,354,069). It describes an intelligent travel-assistant system that uses position data and map information to reason about a traveler's path. This is the single most dangerous reference in the family record because it is pre-critical-date and squarely directed to predicting/assisting a route from position data.
• EP 1 600 910 A3, "System and method for dynamic navigational route selection" (Sunnyvale, CA) — teaches a navigation system that factors transient delays into routing, keeps track of the routes traveled by the vehicle and the times of transit, and uses stored historical data to calculate a route. Directly relevant to L8/L9 (route history → route calculation).

Category-B references (well-known art in the field; specific numbers require verification against the patent's "References Cited" list, which I could not retrieve):

• Map-matching / snap-to-road (L3): the extensive pre-2002 literature on correlating GPS fixes to the nearest link (e.g., patents commonly identified as US 5,808,565; US 5,999,129; US 6,192,312). Verify numbers.
• Dead-reckoning / predictive vehicle position (L4–L7): GPS/INS-integrated navigation patents that extrapolate vehicle position between fixes using speed and heading, principally to keep a map display continuous through signal loss.
• Route engine with preferences (L8): commercial and patented routing (fastest/shortest; avoid-highways/tolls) in DeLorme, Microsoft Streets & Trips, and navigation patents of the 1990s (e.g., US 5,808,566 to Behr; DeLorme's travel-planning art).
• Dispatch / vehicle ordering (L10): 1990s dispatch systems ranking vehicles by proximity/ETA (e.g., US 5,978,731 to Booker, "System and method for automatically providing vehicle status information"; Qualcomm OmniTRACS-type AVL).
• AVL breadcrumb display (L1–L2): standard fleet-tracking GUIs.

4. Obviousness combinations

Combination 1 — Predictive position (L1–L7, incl. asserted claim 11)

Primary: dead-reckoning/predictive-position navigation art. Secondary: map-matching art (L3). Tertiary: AVL breadcrumb display (L1–L2).

• Teaching: AVL systems plot discrete fixes (spec. admits this); dead-reckoning navigation extrapolates a present/forward position from the last fix using speed and heading; map-matching keeps the plotted point on the road centerline.
• Motivation (KSR rationale A & C): A POSITA seeking to mitigate the disclosed "breadcrumb" deficiency — a discontinuous display between sparse updates — would predictably improve the display by extrapolating the last known position along the road network. Both references are in the same field (navigation/positioning), address the same problem (sparse or lost GPS), and the result (a continuous predicted position on the mapped road) is precisely the "predictable result" KSR contemplates. Using a known technique (dead reckoning) to improve a known device (AVL/navigation display) is the paradigm of KSR rationale C.
• Finite solutions (rationale G): When the device reaches a fork, the only options are the finite branches of the network; displaying all branches is the "finite number of identified, predictable solutions" scenario. This is exactly L6.

Combination 2 — Estimated route from discrete points (L8–L9)

Primary: route-calculation engine with preferences. Secondary: map-matching. Tertiary: discrete location-history (breadcrumb) record.

• Teaching: Route engines calculate a path between two points over the road network using preferences; breadcrumb records supply two discrete points.
• Motivation (rationale A & F): Substituting consecutive breadcrumb points as the "origin" and "destination" inputs of a known route engine is a simple substitution yielding the predictable result of a plausible path between them — and it addresses the market force (fleet/dispatch customers wanting actual distance traveled and directions, not straight lines) that the spec itself identifies. EP 1 600 910 A3 expressly teaches tracking routes traveled and feeding that history back into route calculation, supplying the "why" to combine.

Combination 3 — Dispatch ranking (L10)

Primary: dispatch/vehicle-sequencing art. Secondary: route engine (Combination 2).

• Teaching: Dispatch systems already rank vehicles by proximity; route engines already compute network distance/time.
• Motivation (rationale C & F): The spec itself disparages line-of-sight (LOS) ranking and posits route-based ranking as the improvement. A POSITA would substitute network-route distance/time for LOS distance because it is more accurate for the dispatch decision — a known technique applied to a known device to improve it in the same way, with a predictable, beneficial result.

Combination 4 — Predictive + destination ("pseudo real-time")

Primary: Combination 1 + a route-guidance/destination-input reference.

• Where destination is known, predicting forward along the route from the last fix is the straightforward use of route-guidance art to fill update gaps (rationale A).

5. Counter-arguments and secondary considerations to test

• Teaching away / unexpected results: The patent's stated advantage is a "better illustration" and metrics like total distance; these are predictable benefits of applying known routing to known position streams, which weakens nonobviousness. I found no evidence of unexpected results or a recognized teaching away in the materials reviewed.
• Secondary considerations (nexus): Commercial success of modern turn-by-turn navigation is not probative absent a nexus to the claimed combination; the features here largely reflect industry-wide practice, not a patented advance.
• The "snap-to" and "predictive position" concepts were demonstrably conventional by 2002, and the patent concedes the environment; the inventive weight (if any) sits in narrow implementation details, not in the independent-claim concepts.

6. Bottom line (with confidence levels)

1. High confidence: The broad independent claims (e.g., asserted claim 11 — predicting a position between discrete updates and displaying a partial route) are vulnerable to a §103 rejection over dead-reckoning/predictive-navigation art in view of map-matching art, with the AAPA in the spec supplying the AVL/breadcrumb environment. The "alternative predictive position at a fork" (L6) is a finite-solutions, predictable-result combination under KSR.
2. Medium confidence: The estimated-route and dispatch-ranking limitations are obvious over route-engine art (preferences) combined with breadcrumb history and dispatch-sequencing art; EP 1 600 910 A3 and Dillenburg strengthen these combinations.
3. The most probative single reference I identified is Dillenburg et al. (Mar. 15, 2002) — already in the family record — alone or in combination with map-matching art.

Caveats / verification required:

• The "References Cited" list and the full prior-art section of US 9,746,341 (and the '155/'069 ancestors) were not available to me; the Category-B reference numbers above are representative and must be verified before being asserted. Do not treat the bracketed patent numbers as confirmed citations to this patent.
• Whether the '341 claims are actually entitled to the 2002 priority date (vs. an intervening-date issue) should be confirmed from the file wrapper; the pre-AIA framework assumes entitlement.
• I did not locate any IPR/PGR or court §103 ruling on the '341 patent in this pass; the validity fight appears to be at the district-court stage (Bluestone Ventures v. Google, 7:25-cv-00569). A well-funded defendant would very likely mount a §103 (and §101) defense on this record.

Would you like me to (a) pull the exact "References Cited" lists for US 9,746,341 / 7,565,155 / 9,354,069 to replace the Category-B placeholders with verified citations, or (b) retrieve the asserted-claim text of claim 11 so the element-by-element mapping is exact?
