US 10677608

I'll research US patent 10677608 across USPTO records and litigation dockets.

Let me dig into the claims, litigation, and any 2026 CAFC docket activity.

Let me retrieve the actual claim language and check for any Federal Circuit activity.

US Patent 10,677,608 — Research Summary

Scope note: I searched general web/patent aggregators (Google Patents, Unified Patents, FreePatentsOnline, Espacenet), USPTO-derived records, and Federal Circuit/litigation sources. I did not have direct authenticated access to USPTO Patent Center or PACER, so docket details come from secondary aggregators (CourtListener/RECAP, Dockets.Justia, PacerMonitor, RPX, Unified). I flag uncertainties explicitly below.

Bibliographic Data

Caveat: The "expired" status and 2023 expiration date come from Unified Patents/Google Patents, which expressly label such entries assumptions, not legal conclusions. I did not independently verify term/expiration against a USPTO fee record.

Abstract (verbatim from the patent)

"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 Claims

Important uncertainty: The full claim set text was not returned by my searches (the Google Patents page content I retrieved included the abstract, description, and classifications, but not the numbered claims). I therefore reconstructed the independent-claim substance from (a) the patent's own specification and (b) claim-element quotations in Bluestone's infringement complaint (which quotes claims 1–4 of the '608 patent). Treat the reconstruction as indicative, not verbatim.

Based on those sources, the '608 patent appears to have a primary independent claim (claim 1) directed to a mobile computing apparatus/device that:

1. Includes/uses a GPS receiver, display, processor, and memory (i.e., a smartphone/navigation device);
2. Displays a map on the device;
3. Determines a starting location and a destination location for the device;
4. Calculates a first route from the starting location to the destination location (and, per the specification, at least one additional/alternative "possible route") using digital map data rather than straight-line breadcrumb connections; and
5. As the mobile computing device travels, causes the device to remove from the display at least a portion of the routes previously displayed on the map — i.e., it dynamically cleans up/replaces stale route graphics as the user moves.

Selected dependent claims (as quoted in the complaint, so closer to verbatim):

• Claim 2: the starting location is derived from GPS information associated with the device.
• Claim 3: the starting location is derived from a user input.
• Claim 4: calculating the first route is based at least in part on a mode of travel associated with the device (car/bike/foot, etc.).

Bottom line in plain terms: The claimed invention is a GPS-enabled mobile navigation device that computes route(s) over mapped road data, displays them, and dynamically updates/removes route graphics in real time as the device moves — a "dynamic estimation and predictive route generation" system building on discrete sampled location updates, snapping location points to road segments, and supporting predictive partial routes between position fixes.

I cannot confirm from the sources retrieved whether the '608 patent contains additional independent claims (e.g., a method claim or server-side claim) beyond claim 1, or the exact total claim count. This is a genuine gap — numbers such as "claims 1–N" or the precise count of independents should be verified against the granted patent PDF.

Litigation / Docket Findings

Federal Circuit (CAFC) 2026 dockets: I found no CAFC 2026 docket or appeal involving US 10,677,608. My searches for the patent number in connection with CAFC 2026 returned only unrelated appeals (e.g., Intuit Inc. v. SameSurf, Inc., No. 2024‑2298, Rule 36 judgment Apr. 7, 2026; REGENXBIO v. Sarepta, No. 2024‑1408; Ironburg Inventions v. Valve, No. 2024‑2088) — none of which concern the '608 patent. If the '608 patent is being litigated at the district level (see below), any appeal would only reach the Federal Circuit after a final judgment, so its absence from 2026 CAFC dockets is expected.

Active district-court litigation: Google Patents flags this patent family as having litigation, and I confirmed:

• Case: Bluestone Ventures, Inc. v. Google LLC
• Court: U.S. District Court for the Western District of Texas (Midland/Odessa Division), Case No. 7:25‑cv‑00569
• Filed: December 12, 2025
• Judge: David Counts (referred to Magistrate Judge Derek T. Gilliland)
• Plaintiff's counsel: Raymond W. Mort III, The Mort Law Firm, PLLC
• Accused products/services: Google Maps services and Google Pixel devices
• Asserted patents: The complaint asserts a portfolio of related Bluestone patents, including the '608 patent (identified in the complaint as "United States Patent No. 10,677,608," issued June 9, 2020, to the four named inventors) alongside siblings such as the '341, '337, '071, and '925 patents.
• Docket activity into 2026: Summons returned executed (Jan. 26, 2026); answer/notices (late Mar.–early Apr. 2026); Rule 26(f) report (Apr. 13, 2026); Scheduling Order (Apr. 22, 2026); a "Transfer Case" entry (Apr. 23, 2026); and a sealed motion (Apr. 24, 2026). The April 23 "transfer" entry suggests the case may be moving to another division or judge, but I could not confirm the destination from the secondary source.

Caveat: The docket details above are drawn from CourtListener/RECAP, Dockets.Justia, PacerMonitor, and RPX aggregations rather than direct PACER review; the most recent entries (transfer, sealed motion) are unverified and I cannot state their substance.

Explicit Uncertainty Flags

1. Full claim text not obtained — independent-claim recitation above is partly reconstructed from the specification and complaint quotations; verify against the granted patent.
2. Expiration date (2023‑04‑10) and "Expired – Fee Related" status are aggregator entries labeled as assumptions, not USPTO conclusions I verified.
3. No CAFC 2026 docket for this patent was found — reported as a negative search result, not proof of nonexistence.
4. Priority date is listed inconsistently across sources (2002‑04‑10 vs. 2002‑04‑09 in some family-member records); I used 2002‑04‑10 per the patent's own continuation chain and Google Patents.

I'll search for litigation involving US patent 10677608 across litigation databases and court sources.

Let me dig into the specific litigation reference and the patent owner.

Litigation Involving U.S. Patent No. 10,677,608 ("the '608 patent")

Patent identity check (important): I searched literally for the granted patent number 10,677,608, titled "Method and System for Dynamic Estimation and Predictive Route Generation," assigned to Bluestone Ventures, Inc. (inventors: Michael Sheha, Angie Sheha, Stephen Petilli, Arun Yarlagadda; priority date April 10, 2002; granted June 9, 2020). Searches also returned two lookalikes that are NOT this patent and should be excluded:

• Application No. 10/677,608 (US 2005/0075975 A1, "Allocating Funds for Payment of Transactional Account Statements," In2m Corp) — a different application serial number, not this patent.
• Belgian patent 10677608 (Keller G.m.b.H.) — an unrelated foreign number.

I did not auto-correct or merge these.

Known Litigation

1. Bluestone Ventures, Inc. v. Google LLC — ACTIVE

Note on patent status: The '608 patent is listed as "Expired – Fee Related" with an anticipated expiration of April 10, 2023 (20 years from the 2002 priority date; see https://patents.google.com/patent/[US10677608](/patent/US10677608)/en and Unified Patents patent page https://portal.unifiedpatents.com/patents/patent/10677608). The 2025 suit therefore appears aimed at past/back damages for the pre-expiration period, not injunctive relief.

2. Bluestone Ventures Inc. v. Uber Technologies, Inc. — CLOSED, RELATED FAMILY (asserted-patent attribution UNCERTAIN)

Caveat: This Uber case surfaced when filtering Unified Patents' litigation caselist by the IP identifier "10502" (which corresponds to a sibling patent in the same Bluestone/Sheha family, e.g., U.S. Pat. No. 10,502,583 — a continuation in the same chain as the '608 patent). That search result does not, by itself, confirm that U.S. Pat. No. 10,677,608 specifically was asserted against Uber. I am flagging it as a family-related case, not a confirmed '608 assertion. I could not independently confirm from the search results that the '608 patent was named in the Uber complaint.

Coverage gaps / what I could not confirm

• No IPR, PGR, or other PTAB post-grant proceeding against the '608 patent appeared in searches. I cannot rule one out; I did not find one.
• PACER was not directly queried (paywalled); docket details above are from PACER-derived aggregators (CourtListener/RECAP, Justia, RPX, Docket Alarm, PacerMonitor) and may lag the official docket.
• The Google Patents family page references a "first worldwide family litigation" entry via Darts-IP (family 34395939: https://patents.darts-ip.com/?family=34395939). This indicates additional family-wide litigation may exist across jurisdictions/patents sharing the same priority family (not necessarily the '608 patent itself). I could not enumerate those from the available results.
• The Unified Patents record shows the litigation is associated with the Bluestone Ventures entity, which Unified classifies as an NPE (patent assertion entity) in the related '502 case.

Bottom line

The only confirmed active litigation specifically involving U.S. Pat. No. 10,677,608 is:

Bluestone Ventures, Inc. v. Google LLC, No. 7:25-cv-00569 (W.D. Tex., filed Dec. 12, 2025) — pending, with Google's answer filed and a scheduling order entered in late April 2026.

A closed, same-family case (Bluestone Ventures Inc. v. Uber Technologies, Inc., No. 6:21-cv-00685, W.D. Tex., filed June 29, 2021) exists but its assertion of the '608 patent specifically is not confirmed by the sources retrieved. If you need court-record certainty on the Uber case or on any foreign/family proceedings, I recommend pulling the complaints directly from PACER/RECAP for 6:21-cv-00685 and checking Darts-IP family 34395939.

I'll verify the structured data with targeted searches before concluding, since this patent has a live litigation campaign (Texas Western District Court, case 7:25-cv-00569) that could have triggered AIA petitions.

The first pass returned no hits for this patent. Let me refine with the owner entity name and the litigation campaign, which is the usual trigger for AIA petitions.

Litigation is confirmed (Bluestone Ventures v. Google, W.D. Tex.). Let me check whether that campaign, or any earlier one, produced an AIA petition against this patent or its siblings.

PTAB / AIA Trial Analysis — U.S. Patent No. 10,677,608 ("Method and System for Dynamic Estimation and Predictive Route Generation")

Proceedings overview

Total AIA trial proceedings on file: 0 (zero). The structured "PTAB proceedings on file" block supplied from the USPTO Open Data Portal returns no IPR, PGR, or CBM for US 10,677,608, and my independent web checks (PTAB E2E, Docket Alarm, RPX/Unified Patents portals, and general docket searches by patent number and by patent owner) surfaced no petition, institution decision, Final Written Decision, or appeal naming this patent. Because there are no proceedings, there is no breakdown by status — the defensive posture this gives a defendant is not "hardened patent," but rather "no validity challenge has ever been filed at the PTAB against this patent." That cuts both ways: the claims are entirely untested in an AIA forum, so there is no FWD to lean on, but also no IPR estoppel has been created and no claim has yet been canceled. I flag this as an absence of evidence, not proof of a clean history — smaller-volume assertion campaigns can lag petition filings by quarters, and the ODP ingest is not instantaneous.

No proceedings to report

I will not fabricate entries to fill the template. There are no IPR-####-##### / PGR-####-##### / CBM-####-##### numbers, petitioner names, panels, or dispositions to populate for US 10,677,608. Any proceeding recited for a "608" patent that a search may surface should be scrutinized: U.S. 10,268,608 (Netlist) is a different patent with a similar trailing number, and the Samsung/Micron IPRs on that Netlist patent are not proceedings on US 10,677,608. (Source of that unrelated hit: press coverage of Netlist's '608 patent, not this one.)

Strategic summary

Claim status: all claims UNTESTED. No claim of US 10,677,608 has been canceled, confirmed, or even instituted for review at the PTAB. There is therefore no "surviving claim set" narrowed by an FWD, and equally no dead claims a defendant can dismiss out of hand. For a defendant, every claim asserted against you is live until a court or the Board says otherwise. Notably, the Google Patents record shows this patent is one of a large continuation family sharing a 2002-04-10 priority date (Bluestone has separately asserted siblings including US 9,921,077, US 10,502,583, US 9,746,341, US 10,274,337, and US 10,551,208), so a validity strategy aimed at the family's common specification and priority chain would be portable across the portfolio — but no IPR has yet been filed against any of them that I could locate.

Estoppel landscape: clean slate. Because no petitioner has taken this patent to the Board, § 315(e)(2) estoppel does not attach to anyone. A defendant today retains the full menu of § 102/§ 103 prior-art grounds, and retains the freedom to raise them either in an IPR or in district court (or both). Two timing cautions: (1) if you have already been served with a complaint alleging infringement of this patent, your § 315(b) one-year window to petition for IPR is running — miss it and IPR is barred entirely; and (2) a declaratory-judgment action can trigger the § 315(a)(1) automatic-stay mechanic. There is no existing petitioner whose estoppel shadows your grounds, and no risk of a "same or substantially the same prior art" § 325(d) discretionary denial being anchored to an earlier petition on this patent — the Board has no prior record here.

Pattern signals. Two things stand out. First, the assertion is active and recent: Bluestone Ventures, Inc. sued Google LLC in the Western District of Texas (Case No. 7:25-cv-00569, filed 2025-12-12 per RPX) accusing Google Maps of, among other things, predicting device position between GPS updates and dynamically adding/removing route paths — exactly the subject matter of this family. Bluestone has also asserted sibling patents against Uber. Second, there is no defensive aggregator in the chain on this patent: the Unified Patents and Darts-ip links on the Google Patents page are litigation-database references, not signs that Unified Patents has petitioned. So the typical "well-asserted patents eventually attract IPRs" dynamic has not yet played out here, but the ingredients for one (well-funded accused infringer + active NPE-style campaign + old 2002 priority art) are all present.

Recommended next steps

• If you are a defendant and looking for an easy kill: there isn't one on file. No FWD exists to cite, so you cannot say "claims 1–5 are canceled." Do not represent to a court or adversary that any claim has been invalidated at the PTAB — none has.
• Preserve your IPR window. If you have been served with an infringement complaint on US 10,677,608, calendar the § 315(b) one-year deadline immediately; it is the single most consequential date in your PTAB strategy. Confirm service date and whether any co-defendant or privy has already been served (which can start the clock for you).
• Commission your own prior-art search now. With no Board record, you are writing on a blank slate. The 2002-04-10 priority date and the family's shared specification are the leverage points; a strong § 102/§ 103 mapping on the independent claims (the predictive-routing and dynamic-add/remove-route-display limitations) would be first-impression art before the Board.
• Watch for a first-filed petition. Given the active Google (W.D. Tex.) and Uber campaigns, monitor PTAB E2E (https://ptacts.uspto.gov) and Docket Alarm for a newly filed IPR naming 10,677,608. If a co-defendant or third party (e.g., a defensive aggregator) files first, that changes your estoppel and § 315(b) calculus and may open a joinder path under § 315(c).
• Verify before relying. I could not locate any proceeding, but the ODP ingest can lag and my search is not a substitute for a live PTAB E2E party/patent query or a PACER/PTAB docket pull run on the date you file. Treat the "no PTAB activity" finding as current as of the sources consulted and re-confirm before taking a position.

Sources consulted: USPTO PTAB E2E / Open Data Portal (structured block, no proceedings); Google Patents, https://patents.google.com/patent/US10677608/en; Unified Patents patent portal, https://portal.unifiedpatents.com/patents/patent/10677608; RPX Insight litigation record, https://insight.rpxcorp.com/litigation/txwdce-1172879830-bluestone-ventures-v-google; CourtListener recap for W.D. Tex. Case No. 7:25-cv-00569 (Bluestone Ventures, Inc. v. Google LLC). No FWD, institution decision, or CAFC opinion exists to link to because none has issued for this patent.

I'll research the assignment chain, litigation, and parties before building the report.

Assignment & Ownership Reconstruction — US 10,677,608 B2

Scope note / data provenance. I reconstructed this from Google Patents legal events (the authoritative text supplied), the family's USPTO-registered assignment data as mirrored in Google Patents/Espacenet, RPX Insight, Unified Patents' portal and litigation database, and W.D. Tex. dockets. I was not able to query assignmentcenter.uspto.gov directly in this session, so I could not independently pull the recorded correspondent of record or verify every reel/frame. Where a reel/frame is not in hand, I say so rather than inventing one. Treat reel/frame citations below as verified only where explicitly stated.

Inventors

Unusual patterns — checked:

• No 12-month-inventor-departure pattern. The opposite is true here. All four inventors executed the assignment to Networks In Motion, Inc. with signing dates 2003-10-31 through 2003-11-30 (Reel 022823/0286), and the two principals (Michael and Angie Sheha) continued filing NIM-family applications through at least 2006 (e.g., US 8,019,532, filed 2006-03-07, assigned to TeleCommunication Systems). There is no fire-sale-precursor signature in the inventorship record.
• The founder-couple (Michael and Angie Sheha) hold the overwhelming majority of the family's inventorship (≈29 and ≈28 NIM filings respectively), i.e., this is a founder-controlled portfolio, not a hired-inventor portfolio.
• Petilli/Yarlagadda employer attribution is inferred from co-inventorship on other NIM-assigned filings — moderate confidence, not directly evidenced in the assignment record.

Original assignee

Two "original assignee" facts must be kept distinct, because this is a continuation patent:

A. Entity named on US 10,677,608 as issued (granted 2020-06-09): Bluestone Ventures, Inc., Reston, VA (Espacenet lists applicant "BLUESTONE VENTURES INC [US]"; Google Patents lists original and current assignee as Bluestone Ventures Inc).

B. Original assignee of the priority family (the true origin): Networks In Motion, Inc., Aliso Viejo, CA. US 7,565,155 — the 2003-04-10 non-provisional in this chain — issued on 2009-07-21 to Networks In Motion. Unified Patents records the family's "Original Assignee" as TeleCommunication Systems Inc. for the later continuation (US 2012/0202530), consistent with the intermediate chain NIM → TCS.

• Did the originator ship a product embodying the claims? Yes. Networks In Motion was a commercial location-based-services provider; contemporaneous trade press (TechRockies, 2008) states NIM "powers the AAA Mobile, Verizon VZNavigator, TELUS Navigator, YellowPages.com Mobile" services, and was VC-backed by Mission Ventures, Redpoint Ventures and Sutter Hill Ventures. This is an operating-company origin, not a paper origin.
• Current status: Networks In Motion was acquired (by TeleCommunication Systems); it is not an independent operating entity today. TeleCommunication Systems, Inc. (Annapolis, MD) was itself later acquired by Comtech Telecommunications Corp. — note that the NIM navigation family had already been carved out to Bluestone (recorded 2020-04-21, before the Comtech/TCS combination closed), so the family did not travel with TCS into Comtech. Bluestone Ventures, Inc. is the current owner and, per Unified Patents, is classified as an NPE / Patent Assertion Entity with no products identified in commerce.

Confidence flag: the exact TCS→Bluestone purchase date and consideration are not evidenced in the sources I could reach; only the recording date (2020-04-21) and the pre-filing applicant-of-record status (application filed 2020-01-20 by Bluestone Ventures Inc) are solid.

Assignment timeline

Recorded assignments exist for this patent — this is not a "no records" case.

• 2003-10-31 → 2003-11-30 (executed) / recorded ~2009 — Reel 022823/0286

  • Conveyance: Assignment (Assignment of Assignors' Interest)
  • Assignor: SHEHA, MICHAEL A.; SHEHA, ANGIE; PETILLI, STEVEN; AND OTHERS
  • Assignee: NETWORKS IN MOTION, INC., California
  • Correspondent: Not retrievable in this session — the numbering/search hits surfaced the reel/frame and signing dates but not the recording correspondent. Recommend direct pull from Assignment Center.
  • Context: Founding-team assignment of the priority application to the operating start-up (the origin link of the entire chain).
  • Note the oddity worth flagging to the file: signing dates are 2003 but the assignment was recorded against reel 022823, a reel series consistent with recording around 2009 — i.e., the inventors' rights were recorded late, roughly coincident with issuance of US 7,565,155 (2009-07-21). Late-recorded inventor assignments are a common cause of later "confirmatory" re-papering, which is exactly what appears below.

• ~2010 (executed) / recording data not confirmed — reel/frame not in hand

  • Conveyance: Merger / acquisition (asset transfer)
  • Assignor: Networks In Motion, Inc.
  • Assignee: TeleCommunication Systems, Inc. (Annapolis, MD)
  • Correspondent: unknown
  • Context: Corporate acquisition of the NIM business by TCS; the family's assignee-of-record becomes TeleCommunication Systems, Inc. I could not confirm a separately recorded assignment instrument or reel/frame for this step — flagging as a gap, not asserting a record exists.

• 2020-04-21 (recorded) — reel/frame not in hand (Google Patents legal-event entry: "2020-04-21 Assigned to BLUESTONE VENTURES, INC … ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)")

  • Conveyance: Assignment
  • Assignor: PETILLI, STEPHEN; SHEHA, ANGIE; SHEHA, MICHAEL; YARLAGADDA, ARUN — the four individual inventors
  • Assignee: BLUESTONE VENTURES, INC.
  • Correspondent: Not retrievable in this session.
  • Context: Confirmatory / chain-repair assignment executed directly from the original inventors to Bluestone, recorded ~7 weeks before the '608 grant (2020-06-09) and roughly three months after the 16/747,460 application was filed (2020-01-20) already naming Bluestone as applicant. This is the classic signature of a portfolio purchase where the buyer's counsel takes a direct inventor→buyer instrument to paper over the 2003 late-recorded NIM assignment and the unrecorded NIM→TCS step. This is the key transfer-to-asserter link in the chain.

• No further assignments recorded in the Google Patents legal events for US 10,677,608. Bluestone Ventures, Inc. remains assignee of record.

Family-adjacent events (context, not separate assignments on the '608): continuation applications filed 2020-04-29 (US 10,996,071), 2021-05-01 (US 11,346,684), 2021-05-17 (US 11,473,925), 2022-05-08 (US 11,619,513), all under Bluestone — i.e., Bluestone was actively prosecuting fresh continuations of the family in 2020–2022 while asserting earlier members of it.

NPE / troll-pattern signals

1. Shell-entity transfer — PRESENT (moderate-strength).
   The patent moved from an operating origin (Networks In Motion → TeleCommunication Systems) into a non-operating holder, Bluestone Ventures, Inc., recorded 2020-04-21 (Google Patents legal event), with no product in commerce identified for Bluestone and an RPX/Unified plaintiff profile that is pure assertion. Caveat for the file: the archetypal tells are not confirmed — the entity is an "Inc." and not a single-member Delaware/Texas LLC, and I could not verify a registered-agent address for the Reston, VA address. The call rests on the operating→non-operating transfer plus NPE classification, not on naming.

2. Known asserter in the chain — PRESENT.
   Bluestone Ventures, Inc. is not one of the legacy enumerated NPEs (Acacia, Marathon, IV, Wi-LAN, Conversant, Vringo, Pendrell, etc.), but it is affirmatively listed as an NPE/PAE plaintiff in a public asserter directory: Unified Patents' litigation case list classifies the plaintiff entity type in 6:21-cv-00685, Bluestone Ventures Inc v. Uber Technologies Inc (W.D. Tex., filed 2021-06-29, closed) as "NPE (Patent Assertion Entity)", and the case is tracked in RPX Insight. Bluestone then re-asserted the family against Google LLC, 7:25-cv-00569 (W.D. Tex., filed 2025-12-12), seeking to pre-empt §101/§112 validity attacks on the '208, '337 and '341 family members.

3. Repeat correspondent across the chain — UNCLEAR / not verifiable here.
   I could not obtain the recorded correspondent for the 2003 Reel 022823/0286 entry or for the 2020-04-21 Bluestone entry, so recurrence cannot be established or excluded. Separately, litigation counsel of record is a repeat player: Raymond W. Mort, III, The Mort Law Firm, PLLC (Austin, TX) appears on both the 2025 Google complaint (Dkt. 1–4) and the W.D. Tex. patent docket generally. That is counsel for assertion purposes only — it is not a recording correspondent, and I will not upgrade this signal on that basis alone. Action item: pull the "Correspondent" field for every reel/frame in this chain from Assignment Center to test recurrence.

4. Cascading transfers — UNCLEAR.
   The documented chain has only two confirmed links on the '608 itself (2003 inventors→NIM; 2020 inventors→Bluestone), with one unrecorded/suspected intermediate (NIM→TCS). The 2020→2021→2022 continuation filings (US 10,996,071; 11,346,684; 11,473,925; 11,619,513) all stayed with the same assignee — so on the '608 there is no demonstrated chained-LLC cascade inside 24 months. Not established.

5. Pre-litigation transfer — NOT PRESENT (on available dates).
   Recording 2020-04-21 vs. first identified suit 2021-06-29 (Uber) = ~14 months; vs. the Google suit 2025-12-12 = ~5.6 years. Neither falls inside the 6-month window. (If new continuations were assigned or licensed shortly before the 2025 filing, that would change — unverified.)

6. Bankruptcy fire-sale — NOT PRESENT (as far as determinable).
   Networks In Motion was acquired, not liquidated; no Chapter 7/11 proceeding is evidenced for NIM, TCS or Bluestone. TCS was itself acquired by Comtech Telecommunications Corp. No judicial-sale documentation identified.

7. Privateering — UNCLEAR.
   The factual shape (operating telecom/LBS company's navigation portfolio ending up in an assertion vehicle that sues Uber and Google) is privateering-adjacent, but privateering requires evidence the operating company is asserting through the NPE on its own behalf — typically an SEC 8-K/10-K, a retained economic interest, or licensing-back arrangement. I have no such filing. Do not score this as present without a TCS or Comtech disclosure.

8. Defensive aggregator (anti-NPE) — NOT PRESENT.
   The chain terminates at Bluestone Ventures, Inc., an asserting plaintiff — not at RPX, AST, LOT Network, Unified Patents, or OIN. This patent has not been neutralized.

Additional independent observation (not one of the eight signals): US 10,677,608 carries an anticipated expiration of 2023-04-10 (20 years from the 2003-04-10 filing) and Google Patents shows status "Expired – Fee Related." The 2025 Google complaint in the reported analysis pivots to the '208, '337 and '341 continuations rather than resting on the '608. Any damages theory on the '608 itself is therefore temporally constrained — worth raising in a validity/enforceability review, and material to whether this patent is the asserted or merely the family-anchor reference.

Verdict

NPE — high confidence.

Two strong signals are independently evidenced: (i) the family was moved out of operating hands — Networks In Motion → TeleCommunication Systems → Bluestone Ventures, Inc., the last step recorded 2020-04-21 directly from the four inventors with Bluestone already named applicant at the 2020-01-20 filing — and (ii) Bluestone Ventures, Inc. is affirmatively listed as "NPE (Patent Assertion Entity)" in Unified Patents' public litigation database for Bluestone Ventures, Inc. v. Uber Technologies, Inc., 6:21-cv-00685 (filed 2021-06-29), and has re-asserted the same family against Google in 7:25-cv-00569 (filed 2025-12-12) through repeat W.D. Tex. assertion counsel Mort Law Firm. Caveats that keep this out of "beyond dispute" territory: the assignment correspondent fields are unverified (so the repeat-correspondent tell is untested), and the classic shell-LLC/registered-agent indicia are absent (Bluestone is an "Inc."). Recommend pulling the full reel/frame set plus the Correspondent field for each entry before finalizing.

I'll research US Patent 10677608 and its cited prior art references.

Let me get the specific front-page cited references for US10677608.

Let me retrieve the specific citation lists from patent databases.

I was unable to complete all planned searches (I hit the tool-call limit), so I want to be transparent about what I could and could not verify rather than fabricate a citation list.

1. Confirmed identification of the patent

US 10,677,608 B2 — "Method and system for dynamic estimation and predictive route generation"

Critically, US 10,677,608 is the fourteenth member of one long continuation chain. Per its own Cross‑Reference section it is a continuation of Ser. No. 16/517,566 (now US 10,551,208) → 16/377,228 (US 10,502,583) → 15/887,989 (US 10,274,337) → 15/657,141 (US 9,921,077) → 15/435,283 (US 9,746,341) → 14/997,521 (US 9,607,346) → 14/067,415 (US 9,354,069) → 13/346,265 (US 8,577,390) → 12/929,458 (US 8,095,152) → 12/484,091 (US 7,881,730) → a division of 10/410,740 (US 7,565,155), which claims priority to provisional 60/371,941. Because every member shares the same 2002 specification, they also share essentially the same prior-art landscape.

2. What I could and could not verify about "each patent citation"

• The Unified Patents record for US 10,677,608 lists "Patent Art (8)" and "Referenced By (2)" — i.e., there are 8 examiner/applicant-cited patent references on this patent, and 2 forward citations.
• A FreePatentsOnline result surfaced one apparent cited reference associated with this family: US 4,939,662 — "Navigation apparatus," Nimura et al., July 3, 1990.
• I was not able to retrieve the complete, authoritative "References Cited" (front page, box 56) list for US 10,677,608 within my search budget, and I could not pull the full claim text (the patent text supplied to me is truncated in the Detailed Description and contains no claims section).

Because of the strict instruction not to auto-correct identifiers and not to fabricate, I am deliberately not inventing the other ~7 references or asserting § 102 anticipation against specific claim numbers I cannot read.

3. What I can state with confidence

1. US 4,939,662 (Nimura et al., 1990‑07‑03, "Navigation apparatus") — the one cited reference I found grounded in a search result. It is a pre-2002 U.S. patent, so it is available as § 102(b) prior art against the 2002 priority date. Qualitatively it concerns vehicle navigation/map matching, which touches the "snap-to / route along a road network" concepts, but I cannot responsibly assert which of the 10,677,608 claims it reads on without the claim text.

2. The "Cited By" / Referenced By (35 for the family, 2 for this member) entries are forward citations (later patents citing this one) — e.g., Networks In Motion filings (US 2005/0032527, US 2007/0277100, US 2008/0170679), Microsoft's "location aware mobile-device software development," etc. These are not § 102 prior art against 10,677,608; they are evidence of citation impact only.

3. The substantive prior-art problem the family addresses (as stated in its own Background) is the "breadcrumb trail" of discrete AVL/GPS points that does not tell you the actual road network traveled. Relevant §§ 102/103 art therefore tends to cluster in: (a) map-matching / "snap-to-nearest-road" patents (e.g., Nimura-type navigation apparatus); (b) AVL / fleet-tracking breadcrumb patents; and (c) route-calculation/navigation patents predating 2002.

4. Honest limitation and recommended next step

I could not responsibly produce the requested "full citation + publication/filing date + which claim(s) each reference anticipates" for all 8 references. Doing so requires the actual box‑56 list and the issued claims, neither of which I retrieved. To finish this accurately, pull:

• USPTO PatentCenter / Patent Full‑Text (patft) for US 10,677,608, "References Cited" and the "Claims" section; and
• Google Patents page patents.google.com/patent/US10677608B2/en, which itemizes "Patent art (8)" and links each reference.

If you can supply the claim set (or let me run additional searches), I can then map each of the 8 cited references to specific claims under § 102 with the citation/date/description format you asked for. I'd rather flag this gap than present an unverified list of references as if it were the official citation record.

I'll research the claims and prior art landscape for this patent before building the obviousness analysis.

Let me retrieve the full claim language and the prior-art references cited in this patent family.

I have enough to build the analysis. Note the tool-call budget was reached before I could pull the patent's own IDS/"References Cited" list, so I flag that gap explicitly below rather than inventing citation numbers.

Obviousness Analysis — US 10,677,608 B2 under 35 U.S.C. § 103

Scope note / assumption. The task instructed me to "use the results from the Prior Art section of this page." The only prior-art material actually available to me is (a) the Google Patents "Prior art keywords" for the '608 (location, computing device, route, mobile computing, estimated), (b) references surfaced in secondary searches, and (c) the specification's own admissions. I was not able to retrieve the '608 formal "References Cited"/"Cited By" lists (search budget exhausted). Accordingly, each reference below is labeled Verified (I saw the actual disclosure text) or Reported/Attributed (surfaced but not independently confirmed). Every ground is prefaced with what is genuinely established versus inferred, per the operating rules.

I build on, and do not repeat, the earlier Patent Summary section. Two points from it matter here and are flagged as potential contradictions:

• The prior summary could not obtain the full claim text. I now have verified claim quotations from Bluestone's complaint (they quote claim 1 of the '608 patent), which I use below. This partially resolves that earlier gap.
• The prior summary's element (5) ("remove from display… at least a portion of the routes previously displayed") is now confirmed verbatim as a claim-1 limitation. No contradiction — it is corroborated.

1. The claim limitations to be met

Per the complaint's verbatim quotation of the '608 patent (Exhibit 4) at 19:39–53 and the surrounding discussion:

Dependents (verbatim from complaint ¶¶88–90):

• Claim 2: starting location derived from at least second GPS information.
• Claim 3: starting location derived from a user input.
• Claim 4: first-route calculation based at least in part on a mode of travel (car/bike/foot).

Caveat (carried forward, still unresolved): I cannot confirm the total claim count or whether additional independent claims exist. This analysis is directed to claim 1 and dependents 2–4 as those are the only claim texts I could verify.

2. Level of ordinary skill (POSITA)

A POSITA here would have a bachelor's degree in EE, CS, or geomatics (or equivalent) plus ~2 years' experience with in-vehicle/personal navigation, digital map data, route computation, and GPS/wireless location — a routine skill level for 2002 consumer navigation. This matters because nearly every element above was conventional consumer-navigation functionality by the 2002 priority date.

3. Prior-art references

Verified (I read the disclosure text):

1. EP 0 587 892 B1 (navigation apparatus). Claim 1 recites a central processing section with a "possible route operation means for determining two or more possible routes (23, 24) along which said moving object can reach the destination (22) by using map data stored in said memory section, and for driving said display section so that the present position and the destination are indicated," plus an input section for inputting the present position/destination, memory, and display. This is a near-verbatim teaching of limitations B, C, E, F (map-data route computation), and G (display of multiple possible routes).

2. US 5,430,653 (navigation apparatus). Discloses an explicit route-erasure ("indication erasion") process — "erase an indication of the route on the display 14 and to delete the registered route intersection(s)" — i.e., removing displayed route graphics from the map.

3. US 2002/0065603 A1 (Watanabe et al., Nissan). Vehicle-position apparatus that corrects a GPS-computed vehicle position onto the road/map link ("traveling link") — i.e., map-matching/"snapping." Filed Nov. 14, 2001 (pre-AIA §102(e) date), published May 30, 2002.

4. US 6,418,374 B2 (navigation device). Estimates present position from accumulated sensor values and positional data with map matching, and displays position on the map — relevant to limitations D/F (position estimation and map correlation).
   Source: https://patentimages.storage.googleapis.com/53/a3/4e/22b15bd1c96689/US6418374.pdf

5. US 6,108,603 A (Magellan) — dynamic traffic/route determination, cited within the family's art; supports real-time route recalculation/replacement (relevant to H).
   Source: https://patents.google.com/patent/US7269507/fr#7

Reported / attributed (flag: not independently confirmed here):

• US 6,208,934 B1 (Behr) — vehicle navigation with route guidance; surfaced in related IPR materials (but those IPRs, e.g., Fumarolo/Sheha/Van Bosch combinations, concern different Sheha patents — buddy/POI location — not the '608; see ptacts.uspto.gov petition excerpts). Do not assume those IPR grounds transfer to the '608.
• US 6,917,878 / 7,089,110 ("Dynamic navigation system") — excluded as prior art: earliest filing 2003-04-30, after the '608 priority. https://patents.google.com/patent/US6917878B2/en

Specification self-admissions (usable as prior-art evidence): The '608 specification itself treats the following as known: route preferences categories "Driving Speeds / Route Optimization Goals (Fastest vs. Shortest) / Road Preferences (avoid Highways/Arterial/Toll)" (¶ on route preferences); and snapping the device location to the nearest map segment because both GPS and map data carry positional error ("the map data is preferably used as the datum, and the mobile device's location information is 'snapped-to' the nearest point or segment"). These admissions directly support F and D.

4. Grounds of rejection

Ground 1 (primary): EP 0 587 892 B1 in view of US 5,430,653 and US 2002/0065603 A1

• A–C, E, F, G: EP 0 587 892 discloses the hardware (processor/memory/display/input), map display, origin+destination, route computation over map data, and the determination and display of two or more possible routes — mooting A–G except the GPS-derived estimated location.
• D: US 2002/0065603 (GPS + map-matching onto a road link) supplies deriving a device location from GPS and snapping it onto the map; the '608 specification concedes snapping is known.
• H: US 5,430,653 supplies removing a displayed route indication from the map.
• Motivation to combine (KSR / MPEP 2143):
  (i) Same field / analogous art — all three are vehicle-navigation map-display systems; EP 587 892 and US 5,430,653 are both directed to managing what is drawn on the navigation display.
  (ii) Predictable result — combining multi-route display with route erasure yields nothing more than the expected decluttering of the map as the vehicle moves (the classic "arrange old elements, each performing its known function" rationale).
  (iii) Design incentive — a navigation display that shows several candidate routes creates screen clutter; erasing the untaken/traveled route portions is an obvious ergonomic improvement.

Ground 2: Ground 1 further in view of US 6,108,603 (dynamic rerouting)

The "as the mobile computing device travels, remove … routes previously displayed" limitation (H) is met by real-time route replacement: a navigation system that continuously recomputes/replaces the active route (as in dynamic-traffic rerouting) necessarily drops the superseded route from the display. US 6,108,603 (dynamic traffic) and US 6,418,374 (continual position estimation/redraw) supply this continuous-update behavior. Motivation: keeping a stale route on-screen misleads the driver — a recognized problem in the field (the '608 specification itself frames the problem as prior systems leaving "no indication of which roads… were taken").

Ground 3 (alternative, on the "road preference / optimization goal" element F)

Independent of the above, limitation F's "route optimization goal or road preference" is met by the specification's own admission that Fastest/Shortest goals and avoid-highways/tolls preferences were conventional route-computation parameters. Because the claim uses "or," a reference teaching either a route optimization goal or a road preference suffices; EP 587 892's route computation over map data plus the admitted ubiquity of these preferences renders F obvious.

Dependent claims

• Claim 2 (starting location from second GPS information): Obvious over any GPS-based navigation reference (EP 587 892's present-position input; US 2002/0065603). Once GPS fixes the estimated location (claim 1, element D), using a GPS fix as the starting location is a mere duplication of the same known function — the definition of obviousness. No new art required.
• Claim 3 (starting location from user input): Obvious; entering an origin/address is routine and is disclosed by EP 587 892's "input section for inputting the present position and the destination."
• Claim 4 (mode of travel): Obvious; vehicle-vs-pedestrian routing profiles were conventional, and EP 587 892's map-data route computation plus the admitted route-preference paradigm (driving speeds by road class) makes mode-dependent parameters an expected design choice. (Note: I did not verify a single reference expressly reciting car/bike/foot modes; a formal office action should cite one.)

5. Weaknesses, risks, and honest caveats

1. The automatic-removal limitation (H) is the linchpin and the soft spot. US 5,430,653's erasure is user-initiated (a cancel-key count drives the erasing routine), so a robust §103 ground should pair it with a continuous-update/rerouting reference (Ground 2) or argue the "as the device travels" refresh is an obvious design choice. Without that pairing, Patent Owner can argue the references teach erasure only on explicit user command.
2. Priority-date exposure. The '608's claimed subject matter (plurality of possible routes + dynamic display cleanup) may not be supported by the 2002-04-10 provisional (60/371,941); the earliest non-provisional in the chain is 10/410,740 filed 2003-04-10. If the claims are entitled only to 2003-04-10, the prior-art universe expands to include mid-2002 filings (e.g., the US 6,917,878 "Dynamic navigation system" family, priority 2002-04-30, and US 2003/0036848 (Sheha)). This is a threshold issue worth pressing.
3. Verification gaps. (a) I could not retrieve the '608's formal IDS/"References Cited" or "Cited By" lists — a proper analysis must start there; (b) US 6,418,374 and US 6,405,128/6,381,533 issue dates sit at or just after the 2002-04-10 priority and their filing dates must be checked before relying on them; (c) I did not confirm a single reference teaching mode-of-travel route parameters (claim 4).
4. Posture note (not §103, but context): Bluestone's complaint pleads validity under §101 only (¶¶87–90), quoting the same "remove from the display" element it uses for eligibility. That signals the likely defense battleground is Alice/101 — but if the §101 pleadings fail to distinguish the prior art, the same "dynamic display cleanup" hook used to defend eligibility is the element a §103 challenger will attack. The eligibility and obviousness arguments therefore pull in opposite directions.

6. Bottom line

On the record I could verify, claim 1 of the '608 patent is vulnerable to §103:

• EP 0 587 892 B1 supplies the mobile/vehicle computing apparatus, map display, origin+destination, map-data route computation, and display of multiple possible routes (limitations A–C, E–G).
• US 2002/0065603 A1 (or the '608's own admitted snapping) supplies GPS-derived location correlated to the map (D).
• US 5,430,653, reinforced by US 6,108,603/US 6,418,374, supplies the removal of previously displayed route graphics (H).
• The road-preference/optimization-goal element (F) is met by the specification's own admissions.

Because all references are in the same field of vehicle/personal navigation map display, and because the combination yields only the predictable benefit of a less-cluttered, continuously refreshed route display, a POSITA would have had ample motivation to combine them under KSR. Dependents 2–4 add essentially no independent subject matter and fall with claim 1. The one element requiring careful evidentiary support is the automatic (device-moving) character of the removal in limitation H and the priority-date question — both of which a petitioner should shore up before filing.
