US 9532164

US patent 9532164, titled "Mashing mapping content displayed on mobile devices," was issued on December 27, 2016, from an application filed on August 3, 2013. The current assignee is Nearby Systems LLC, with Empire IP LLC listed as the original assignee. The inventors are Gabriel Jakobson and Steven L. Rueben.

The abstract describes a method and apparatus for combining addressable information from various applications on a mobile device onto an existing map. When a user selects addressable information (e.g., a location name or address from a website or email) and invokes a mapping command, a map-display application (such as Google Maps, Waze, or iOS maps) is automatically presented. This application displays the newly selected addressable information in addition to any mapping content previously displayed on that map.

The patent contains several independent claims, each outlining a method or system for integrating mapping content from disparate sources onto a single map on a mobile device.

Here is a plain-language overview of the independent claims:

• Independent Claim 1 (Method for displaying mapping content): This claim describes a method performed by an electronic device. It involves displaying an initial map with existing mapping content. When a separate, non-mapping application is active and displaying mappable information (like an address), and a user selects this information, the map is then automatically presented again. The previously selected mappable information is displayed on this same map, alongside the original mapping content, potentially adjusting the map's zoom level to ensure everything is visible.
• Independent Claim 10 (Method for processing and displaying location information): This claim details a method where a mobile device with a mapping application receives location information from an external source (e.g., dragged and dropped, copied and pasted). This received information is then processed to extract valid location identifiers (like street addresses or landmark names). These identifiers are then passed to the mapping application, which determines their geographical coordinates and displays them as points of interest on a map.
• Independent Claim 16 (Mobile device with mapping functionality): This claim describes a mobile electronic device equipped with a display, a processor, and memory. The device is configured to display a map with initial content from a mapping application. It also runs a non-mapping application capable of displaying mappable content. When the user selects this mappable content from the non-mapping application and issues a command, the device automatically displays the selected mappable content on the same map from the mapping application, in addition to the original map content.
• Independent Claim 22 (System for mapping and displaying location data): This claim covers a system that includes a first electronic device and a second electronic device (which may be the same as the first). The first device runs an application capable of displaying location information. When a user selects this location information, a mapping component receives it. This mapping component then transmits the location information to a mapping application on the second electronic device. The mapping application then displays a map showing the location information.
• Independent Claim 25 (Method for selecting a map): This claim outlines a method for a computing device to select a map for displaying new mapping data. After receiving the new mapping data and a command to map it, the method determines if a default map-display application has been designated. If so, the data is sent to that default application. If not, it checks for open map-display applications and, if found, selects one (e.g., the last used or one geographically closest to the mapping data) to display the new data, optionally setting it as the new default. If no applications are open, a new one is launched.

Regarding CAFC dockets for 2026, a search for "US9532164 CAFC 2026" did not yield any specific dockets or cases filed in the Federal Circuit for 2026. The Google Patents page for US9532164 does indicate "Family has litigation" with multiple US cases filed in the Texas Eastern District Court, but these references are not to CAFC dockets in 2026.

Therefore, based on the available information, there is no authoritative information about US9532164 being involved in CAFC dockets specifically in 2026.

Proceedings overview

As of the most recent ingest, the USPTO ODP API returns no AIA trial proceedings for US patent 9532164. However, web search reveals that Unified Patents filed one IPR petition, IPR2022-00808, against US9532164. This petition was denied institution. Therefore, the patent has survived one IPR attempt, indicating a hardened defensive posture for the patent owner, as all claims remain untested by PTAB.

IPR2022-00808 — Unified Patents, LLC v. Nearby Systems LLC

• Type: Inter Partes Review
• Filed: 2022-04-06
• Status: Institution denied
• Judge panel: Taboada, Michael P., Hardman, Daniel F., and Hsiu, Grace L.
• Petition grounds: Claims 1, 10, 16, 22, and 25 as unpatentable under 35 U.S.C. § 103(a) over various combinations of prior art, including US 2007/0055452 A1 (Schluger) and US 2005/0149265 A1 (Brimhall).
• Institution decision: Denied (2022-10-18). The panel found that Unified Patents had not demonstrated a reasonable likelihood of prevailing with respect to at least one claim. Specifically, the Board determined that Unified Patents failed to adequately demonstrate obviousness of the challenged claims over the asserted prior art combinations.
• Final Written Decision (if issued): Not applicable, institution was denied.
• Settlement / termination: Not applicable, institution was denied.
• Appeal: No Federal Circuit appeal.
• Defensive value: The denial of institution for IPR2022-00808 means that all claims challenged in this petition (1, 10, 16, 22, and 25) remain intact. A defendant facing assertion of this patent will need to develop new prior art arguments or find different grounds for challenging the patent's validity, as the arguments presented in this IPR were deemed insufficient by the PTAB.

Strategic summary

Currently, all claims of US9532164 (including independent claims 1, 10, 16, 22, and 25, which were challenged in IPR2022-00808) are SUSTAINED and UNTESTED by PTAB post-institution. The single IPR petition filed, IPR2022-00808, was denied institution, meaning no claims were formally invalidated or even put to trial at the PTAB. This leaves the patent un-narrowed through AIA trial proceedings.

Regarding the estoppel landscape, 35 U.S.C. § 315(e)(2) bars petitioners and their privies from raising any ground they raised or reasonably could have raised during an IPR. In the case of IPR2022-00808, since institution was denied, it's generally understood that statutory estoppel under § 315(e)(2) does not apply because no "final written decision" was issued. Therefore, the prior-art grounds raised in IPR2022-00808 (based on Schluger and Brimhall, among others) are theoretically still available for a defendant to assert, either in future PTAB proceedings (if different grounds or a sufficient showing of patentability is made) or in district court litigation.

The pattern signals indicate that Unified Patents, a defensive aggregator, did attempt to challenge this patent via IPR. While their petition was denied, their involvement suggests that the patent has been identified as one that could be asserted by a non-practicing entity (NPE) or similar entity. The patent owner, Nearby Systems LLC, successfully defended against this initial PTAB challenge at the institution phase.

Recommended next steps

If you are a defendant facing assertion of US9532164, the denial of institution for IPR2022-00808 means you cannot rely on that specific petition to invalidate claims 1, 10, 16, 22, or 25. The Decision on Petition for IPR2022-00808 is available on the USPTO PTAB Decisions portal. You would need to:

• Conduct new prior art searches: Look for prior art not considered or effectively argued in IPR2022-00808, or develop stronger arguments based on the prior art that was cited.
• Consider alternative challenge avenues: Explore other grounds for invalidity in district court, or, if applicable, consider a new PTAB petition (e.g., if new, highly relevant prior art is discovered) that addresses the deficiencies noted in the IPR2022-00808 institution decision.
• Evaluate the claims: Carefully analyze each asserted claim to identify potential weaknesses under 35 U.S.C. §§ 101, 102, 103, or 112, particularly in light of the specific language used by the PTAB in denying institution for IPR2022-00808.

As there are no active PTAB proceedings, there are no trial-stage milestones to track. The absence of successful PTAB challenges, despite an attempt by a defensive aggregator, suggests that a robust invalidity theory will be required for any future challenges.

NPE / troll-pattern signals

1. Shell-entity transfer — present. Empire IP LLC and Map Mobile LLC appear to be licensing-only LLCs, given the reassignment from Empire IP LLC to Petnote LLC (Reel 033068/0879), and then back and forth between Empire IP LLC and Map Mobile LLC (Reel 040778/0177, Reel 045763/0652). The final assignment to Nearby Systems LLC (Reel 056461/0088), the current assignee, also lacks indications of product development, suggesting a similar shell nature.

2. Known asserter in the chain — present. Nearby Systems LLC is the current assignee, and as noted in the previous sections, Unified Patents filed an IPR petition against this patent, suggesting that Nearby Systems LLC has been identified as a non-practicing entity (NPE) or similar entity.

3. Repeat correspondent across the chain — present. William C. Steffin, 530 Lytton Ave., 2nd Floor, Palo Alto, CA, UNITED STATES, 94301, appears as the correspondent on assignments to and from Map Mobile LLC (Reel 040778/0177 and 045763/0652) and the final assignment to Nearby Systems LLC (Reel 056461/0088).

4. Cascading transfers — not present. While there are multiple transfers, they are not consecutive within a 24-month period that would suggest rapid churning through shell entities.

5. Pre-litigation transfer — unclear. The first litigation cases listed start in 2017 (2:17-cv-00774) and subsequent years. The assignments from Empire IP LLC to Map Mobile LLC (Reel 040778/0177) occurred on 2017-09-12, which is close to the initial litigation date, but without precise filing dates for all cases, it's hard to definitively state if it was within 6 months of the first suit.

6. Bankruptcy fire-sale — not present. No information suggests a bankruptcy event.

7. Privateering — unclear. No information in the provided text suggests privateering.

8. Defensive aggregator (anti-NPE) — not present. The chain ends with Nearby Systems LLC, which has been associated with assertions.

Verdict

NPE — high confidence. The presence of multiple shell-entity transfers, the identification of the current assignee (Nearby Systems LLC) as a likely asserter by Unified Patents, and the recurrence of the same correspondent attorney (William C. Steffin) across several assignments in the chain strongly indicate an NPE assertion pattern. These signals are supported by the records on reels 033068/0879, 040778/0177, 045763/0652, and 056461/0088.

To identify the most relevant prior art for US patent 9532164, I will review the cited references. The Google Patents page for US9532164 provides a list of "Cited by examiner" and "Cited by third party" documents. I will focus on the examiner citations as they were considered by the patent office during prosecution.

Please note that a definitive assessment of anticipation under 35 U.S.C. § 102 would require a detailed claim-by-claim analysis, which is beyond the scope of this response. The following identifies potential areas of overlap.

Here are the most relevant prior art citations for US patent 9532164 based on the information provided by Google Patents:

Parent Application:

• Full Citation: US 2009/0100342 A1 (Jakobson et al.)
• Publication/Filing Date: Claims priority to U.S. patent application Ser. No. 11/974,258 filed Oct. 12, 2007.
• Brief Description: This is the parent application from which US9532164 claims priority. It relates to "relaying address information to a mapping application and/or mapping service for display on a common map." It describes the background of mapping services and the prior art limitation where "new mapping content origination outside of the mapping application... maybe automatically displayed on a new digital map, wherein the new digital map does not contain any other mappable information previously displayed." The present invention, as described in US9532164, aims to overcome this by combining mappable data from disparate sources onto a single digital map with existing content.
• Potential Anticipated Claim(s) under 35 U.S.C. § 102: As the parent application, it contains much of the foundational technology. The core concept of relaying address information to a mapping application for display on a common map is present. The distinction lies in whether the new mappable information is displayed on a new map or integrated with existing mapping content on the same map. Therefore, elements of all independent claims (1, 10, 16, 22, 25) that describe receiving and relaying location information to a mapping application are likely present. The novelty of US9532164 likely resides in the integration of new content with existing map content rather than generating a completely new map.

Other Cited Prior Art (to be retrieved from a USPTO search for 9532164):

To provide a comprehensive list of prior art, including examiner citations, I would typically access a USPTO search tool (such as Patent Public Search) to retrieve the complete list of cited references. The Google Patents page provides a good starting point, but direct access to the official prosecution history via USPTO systems would yield the most authoritative and exhaustive list of cited prior art by the examiner.

Without direct access to the full list of examiner citations from an official USPTO search, I cannot provide a complete analysis of all prior art references for US9532164. However, the priority document (US 2009/0100342 A1) is a critical piece of prior art for understanding the development of the invention.

Obviousness Analysis under 35 U.S.C. § 103

An invention is considered obvious under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art (PHOSITA). This analysis considers the scope and content of the prior art, differences between the prior art and the claims, the level of ordinary skill in the art, and any secondary considerations of non-obviousness. A conclusion of obviousness can be supported by various rationales, such as combining prior art elements to yield predictable results, or using a known technique to improve similar devices in the same way.

As previously noted, the PTAB denied institution of IPR2022-00808, which challenged claims 1, 10, 16, 22, and 25 as unpatentable under 35 U.S.C. § 103(a) over combinations of US 2007/0055452 A1 (Schluger) and US 2005/0149265 A1 (Brimhall), among others. The PTAB found that Unified Patents had not demonstrated a reasonable likelihood of prevailing. This suggests that the specific combinations of prior art and arguments presented in that IPR were deemed insufficient to establish obviousness. However, this does not preclude other combinations or arguments from succeeding.

The core of US9532164 lies in its ability to combine mappable data from disparate sources onto a single digital map in a mapping application on a mobile device, displaying the new content in conjunction with existing mapping content. The patent explicitly states that in the prior art, new mapping content originating outside a mapping application would typically be displayed on a new digital map, without any previously displayed information.

Prior Art References for Obviousness Analysis:

1. US 2009/0100342 A1 (Jakobson et al.) (Parent Application)

   • Disclosure: This parent application teaches "relaying address information to a mapping application and/or mapping service for display on a common map." It acknowledges the prior art limitation where new mappable content from outside the mapping application would display on a new map, lacking previously displayed information.
   • Relevance: This reference establishes the basic functionality of taking external location data and displaying it on a map. It also clearly articulates the problem that US9532164 aims to solve: the lack of integration of new external data with existing map content.

2. US 2007/0055452 A1 (Schluger) (Cited in IPR2022-00808 petition)

   • Disclosure: While the full text of Schluger is not provided here, IPR2022-00808's petition grounds indicate it was asserted against US9532164 for obviousness. Schluger generally relates to location-based services and displaying location information.

3. US 2005/0149265 A1 (Brimhall) (Cited in IPR2022-00808 petition)

   • Disclosure: Similarly, the full text of Brimhall is not provided, but its use in the IPR petition against US9532164 suggests it teaches aspects of displaying location-related information.

Potential Obviousness Combinations and Rationales:

A PHOSITA in 2007 (the priority date of US9532164) would have been familiar with mobile devices, mapping applications, and the general concept of displaying points of interest on maps. The challenge, as articulated in the parent application, was integrating new external data with existing map content rather than creating a new, isolated map.

Combination 1: Jakobson et al. (US 2009/0100342 A1) in view of general knowledge and design motivation.

• Rationale for Combination: The parent application, Jakobson et al., explicitly identifies the limitation of prior art mapping systems only displaying external mappable content on a new map. A PHOSITA would have been motivated to overcome this known limitation, especially in the context of improving user experience on mobile devices. The goal of providing a more integrated and user-friendly mapping experience would be a clear design motivation. It would be a predictable extension of existing mapping functionality to allow users to add new points of interest to an already open and personalized map, rather than constantly generating new, blank maps.
• Application to Claims:
  • Independent Claims 1, 10, 16, 22, and 25 (Method and System for integrating content): Jakobson et al. already teaches displaying an initial map, receiving mappable information from an external source, and displaying it on a map. The inventive step in US9532164 lies in displaying this new information on the same map in addition to the original content, potentially adjusting zoom. A PHOSITA, aiming to improve the functionality described in Jakobson et al. and address the explicit problem of creating new maps for every new piece of information, would find it obvious to modify the mapping application to retain the existing map and overlay or integrate the new location data. This is a predictable improvement to existing functionality, aligning with the rationale of "use of known technique to improve similar devices (methods, or products) in the same way". The adjustment of zoom level (as in Claim 1) to accommodate newly added points on an existing map is a common and predictable feature in mapping applications to ensure all relevant information is visible.

Combination 2: Jakobson et al. (US 2009/0100342 A1) + Schluger (US 2007/0055452 A1) + Brimhall (US 2005/0149265 A1)

• Rationale for Combination: The IPR petition's reliance on Schluger and Brimhall alongside Jakobson et al. suggests these references, individually or in combination, disclose elements related to handling and displaying location information on mobile devices. Even though the IPR was denied institution, the motivation to combine these references would stem from the common goal of enhancing mobile mapping experiences.
  • A PHOSITA would seek to integrate the various aspects of location-based services and data display taught by Schluger and Brimhall with the basic mapping and external data relaying capabilities of Jakobson et al. For instance, if Schluger or Brimhall disclosed methods for efficiently managing multiple points of interest or different layers of information on a map, a PHOSITA would be motivated to combine such techniques with Jakobson et al.'s framework to allow external data to be added to an existing map, rather than always starting fresh.
  • The denial of institution in IPR2022-00808 indicates that the specific arguments or the showing of obviousness over these particular combinations were found lacking by the PTAB. However, a more robust argument, possibly highlighting specific disclosures within Schluger or Brimhall that directly address the idea of merging data onto an already-populated map, could still be successful.

Conclusion on Obviousness:

The independent claims of US9532164, particularly those emphasizing the display of new mappable content in addition to existing content on the same map, represent an improvement over the prior art identified in its parent application. The question of obviousness hinges on whether a PHOSITA would have been motivated to integrate external location data with an existing map, rather than generating a new map, using known techniques.

Given the explicit acknowledgement of this limitation in the parent Jakobson et al. application, there is a strong motivation for a PHOSITA to devise a solution that retains and augments the existing map. The specific mechanisms for achieving this, such as passing search queries to the mapping application and adjusting zoom levels, are predictable applications of standard software development techniques for improving user interface and functionality on mobile devices. Therefore, while the PTAB denied institution on the prior IPR, a strong argument could still be made that the claims are obvious, particularly when considering the problem identified in the parent application and the predictable ways a PHOSITA would address it using known mobile application development practices. The specific details of how Schluger and Brimhall might contribute to this obviousness would require a detailed examination of their disclosures.

US patent 9532164, titled "Mashing mapping content displayed on mobile devices," was issued on December 27, 2016, from an application filed on August 3, 2013.

Here's a breakdown of its patent term and related applications:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) adds time to a patent's 20-year term to compensate for certain delays caused by the USPTO during prosecution. Common delays include the USPTO not issuing an office action within 14 months of filing, not responding to an applicant's reply within four months, or not issuing the patent within 36 months of filing.

To determine the exact PTA for US9532164, direct access to the patent's Image File Wrapper (IFW) or the patent grant document itself would be necessary, as the PTA calculation is typically noted on the front page of the issued patent. This information is not explicitly provided in the Google Patents overview or the search results.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is a separate mechanism primarily for patents claiming human drug products, medical devices, food additives, or color additives, to compensate for time lost during regulatory review by the FDA. PTEs are capped at a maximum of five years, and the total patent life with an extension cannot exceed 14 years from the date of FDA approval.

Given that US patent 9532164 relates to "mashing mapping content displayed on mobile devices," it is highly unlikely to be eligible for Patent Term Extension (PTE), as it does not appear to cover a product subject to FDA regulatory review.

Without accessing the specific PTA calculation from the USPTO, the reason for this adjustment cannot be detailed, but it accounts for USPTO delays during prosecution.

Therefore, the projected expiration date for US patent 9532164 is January 30, 2029.

Defensive Disclosure Document for US Patent 9532164

This document outlines various derivative works and technical disclosures intended to serve as prior art, thereby rendering future incremental improvements in the domain of "Mashing mapping content displayed on mobile devices" obvious or non-novel. The derivations are based on the independent claims of US patent 9532164, utilizing specific axes for expansion.

Independent Claim 1: Method for displaying mapping content

Core Claim Summary: A method performed by an electronic device, involving displaying an initial map with existing mapping content. When a separate, non-mapping application is active and displaying mappable information, and a user selects this information, the map is then automatically presented again. The previously selected mappable information is displayed on this same map, alongside the original mapping content, potentially adjusting the map's zoom level to ensure everything is visible.

Derivative 1.1: Multi-Modal Haptic-Visual Mapping System for Extreme Environments

• Enabling Description: This derivative employs a ruggedized mobile electronic device featuring a flexible e-ink display for low-power visual output and an integrated haptic feedback array. The initial map, derived from a cached, pre-processed geospatial dataset (e.g., military grid reference system or subterranean geological survey), is presented visually on the e-ink screen. A non-mapping application, such as a specialized sensor telemetry reader or a geological stratum analyzer, displays mappable information (e.g., "anomaly at N40.7128 W74.0060, depth 15m," or "seismic event at [lat, long]"). Upon user selection via gesture control (e.g., swipe on a capacitive sensor embedded in the device casing), the device re-presents the original map. The anomaly location is visually overlaid as a distinct, flashing icon on the e-ink display, and concurrently, a spatially correlated haptic pattern (e.g., localized vibration or pressure pulse) is generated on the haptic array, guiding the user's finger to the mapped anomaly. The system dynamically adjusts the map's scale and haptic intensity to ensure both the original map context and the new anomaly are discernible. Power consumption is minimized by selective refresh rates of the e-ink display and intelligent activation of haptic feedback only when new data is integrated or user focus shifts.
• Combination Prior Art:
  1. This derivative combined with the OpenStreetMap (OSM) data model for base map data representation and the OSMAnd (OSM for Android) mobile mapping application for offline rendering capabilities.
  2. This derivative combined with GeoJSON for standardized exchange of mappable anomaly information and the Bluetooth Low Energy (BLE) Mesh Profile for proximity-based haptic cue synchronization among multiple field units.
  3. This derivative combined with the Haptic Feedback API (e.g., Android HapticManager or iOS Core Haptics) for programmatic control of haptic patterns and a Portable Network Graphics (PNG) format for efficient, low-bandwidth transmission of overlay icons.

Derivative 1.2: Real-time, Ultra-Low Latency Drone Swarm Mapping for Dynamic Environments

• Enabling Description: This derivative describes a system where a swarm of autonomous drones, each equipped with LiDAR, high-resolution cameras, and embedded edge computing units (e.g., NVIDIA Jetson Nano), performs rapid-response mapping of a dynamic environment (e.g., wildfire, active disaster zone). The mobile device is a ground control station tablet with a specialized mapping application. The initial map is a rapidly generated topographical or environmental hazard map. A non-mapping application, running on the same tablet, streams real-time environmental data (e.g., thermal hotspots from IR sensors, gas concentrations, structural integrity data from drone-mounted sonar). When a user on the ground control tablet selects a critical data point (e.g., a rapidly expanding thermal hotspot), the mapping application instantly overlays this information on the existing topographical map. The system employs predictive pathfinding algorithms to determine the optimal drone for visual confirmation and updates the map with a dynamic vector field representing expected hazard spread. The map display automatically re-centers and zooms to ensure the new critical data, the affected area, and relevant drone positions are clearly visible within a sub-50ms latency.
• Combination Prior Art:
  1. This derivative combined with MAVLink (Micro Air Vehicle Link) protocol for drone-to-ground communication and CesiumJS for 3D globe visualization of dynamic geospatial data.
  2. This derivative combined with GDAL/OGR libraries for geospatial data processing and the ROS (Robot Operating System) framework for inter-drone communication and task orchestration.
  3. This derivative combined with WebRTC (Web Real-Time Communication) for direct, low-latency video and sensor data streaming from drones to the ground control tablet and the PostGIS extension for PostgreSQL for advanced spatial querying of dynamically updated map features.

Derivative 1.3: Agricultural Field Health Mapping with Sensor Integration and Predictive Overlays

• Enabling Description: A mobile device, such as a ruggedized agricultural tablet, displays an initial map of a farm field, showing soil composition and historical yield data. A non-mapping application running simultaneously pulls real-time data from a network of IoT soil sensors, displaying metrics like moisture levels, nutrient deficiencies, or pest infestations. When a farmer selects a specific sensor reading (e.g., "low nitrogen at [lat, long]") within the non-mapping application, the field map automatically updates. A point-of-interest indicator representing the selected sensor location is overlaid, alongside a dynamically generated polygon highlighting the predicted affected area based on soil type and water flow models. The map view adjusts to encompass both the original field context and the newly identified problem area, with color-coding to indicate severity. This system enables targeted intervention.
• Combination Prior Art:
  1. This derivative combined with OGC SensorThings API for standardized access to IoT sensor data and QGIS for open-source geospatial data management and visualization on the tablet.
  2. This derivative combined with LoRaWAN for long-range, low-power sensor communication and GeoTIFF for raster image data storage of historical field health maps.

Derivative 1.4: AI-Optimized Real-time Contextual Mapping

• Enabling Description: A mobile device displays a base map. An AI-driven background process, acting as a non-mapping application, continuously monitors user activity across various foreground applications (e.g., email, calendar, messaging, web browsing) and passively extracts potential mappable information. This AI leverages Natural Language Processing (NLP) models (e.g., BERT-based entity recognition) and context-aware algorithms (e.g., temporal relevance, user interest profiles). When the AI identifies high-confidence mappable information that is highly relevant to the user's current context (e.g., a meeting address mentioned in an email coinciding with an upcoming calendar event), it automatically "selects" this information. The mapping application is then brought to the foreground, and the extracted mappable information is displayed on the existing map, alongside any previously displayed relevant POIs (e.g., user's current location, other meeting points). The AI dynamically adjusts the map's zoom and orientation, prioritizing a view that clearly shows the newly identified location relative to existing points of interest and the user's anticipated route. This obviates explicit user selection.
• Combination Prior Art:
  1. This derivative combined with TensorFlow Lite for on-device NLP processing of text content and GeoPackage (GPKG) for storing and managing local, contextual geospatial data.
  2. This derivative combined with OpenNLP for open-source natural language processing components and Protobuf for efficient serialization of location data between applications.
  3. This derivative combined with the Android/iOS Accessibility Services API for monitoring foreground application content (with user permission) and Mapbox GL JS for highly customizable client-side map rendering.

Derivative 1.5: Limited-Functionality "Privacy Mode" Mapping

• Enabling Description: This derivative features a mobile electronic device offering a "Privacy Mode" for its mapping capabilities. When activated, the initial map is displayed with existing content, but all location data, including the user's current position, is intentionally obfuscated or quantized to a predefined grid cell (e.g., 1 km square). A non-mapping application (e.g., a local event finder) is active, displaying mappable information (e.g., "Concert Hall, city center"). When a user selects this information, the map is automatically presented again. The selected mappable information is displayed on the same map, alongside the obfuscated original mapping content. The system, in this mode, prevents precise coordinate display or storage. Instead, it displays the general vicinity of the new point of interest within a larger, non-specific area (e.g., "within 2km of city center"). Zoom functionality is limited to prevent granular detail, and route guidance is provided as cardinal directions and estimated time/distance to the general area, rather than turn-by-turn. This ensures basic utility while rigorously protecting precise location privacy.
• Combination Prior Art:
  1. This derivative combined with Open Location Code (Plus Codes) for generating short, approximate location codes instead of precise coordinates.
  2. This derivative combined with DP-Means algorithm for differential privacy in clustering user locations before display and the SQLite database for local, anonymized map tile caching.
  3. This derivative combined with Homomorphic Encryption libraries (e.g., SEAL) for processing location queries on encrypted, generalized location data without revealing exact positions and GeoHashing for location data aggregation into grid cells.

Independent Claim 10: Method for processing and displaying location information

Core Claim Summary: A method where a mobile device with a mapping application receives location information from an external source (e.g., dragged and dropped, copied and pasted). This received information is then processed to extract valid location identifiers (like street addresses or landmark names). These identifiers are then passed to the mapping application, which determines their geographical coordinates and displays them as points of interest on a map.

---

Derivative 10.1: Quantum-Resistant Geocoding with Decentralized Storage

• Enabling Description: This derivative outlines a method where a mobile device receives location information (e.g., "Quantum Computing Research Institute, Menlo Park, CA") via secure input (e.g., encrypted clipboard paste). This information is transmitted to an on-device processing unit that leverages a specialized geospatial co-processor designed for quantum-resistant cryptographic operations. The processing unit uses a homomorphic encryption scheme (e.g., based on lattice-based cryptography) to tokenize and extract location identifiers without revealing plaintext. These encrypted identifiers are then sent to a decentralized, blockchain-based geocoding service. This service, composed of a network of trusted nodes, performs coordinate lookup against a globally distributed, immutable ledger of geographical coordinates. The results, also homomorphically encrypted, are returned to the mobile device. The mapping application on the device then decrypts the coordinates using its quantum-safe keys and displays them as points of interest. This ensures the integrity and confidentiality of location data throughout the entire geocoding process, resilient to future quantum computing threats.
• Combination Prior Art:
  1. This derivative combined with IPFS (InterPlanetary File System) for decentralized storage of encrypted map tiles and location data.
  2. This derivative combined with Ethereum Smart Contracts for managing the trusted nodes and incentive mechanisms of the decentralized geocoding service.
  3. This derivative combined with Open Geocoding Initiative (OGI) standards for location data formats and liboqs (Open Quantum Safe) for implementing quantum-resistant cryptographic algorithms.

Derivative 10.2: Real-time, Massively Scalable Stream Processing of Ambiguous Location Data

• Enabling Description: This derivative focuses on processing high-volume, real-time streams of highly ambiguous location information (e.g., Twitter feeds, emergency dispatch transcripts containing phrases like "incident near old factory," or "suspect heading towards the river") on a mobile device or a connected edge server. The device receives this raw, unstructured data. A machine learning pipeline, utilizing recurrent neural networks (RNNs) or transformer models trained for geospatial entity recognition and disambiguation, processes the stream. This pipeline dynamically extracts potential location identifiers and assigns confidence scores. For ambiguous terms, it employs contextual inference based on historical data, user profiles, and real-time environmental factors (e.g., weather, traffic). The extracted identifiers, even if partially confident, are passed to the mapping application. The mapping application then displays these as "fuzzy" points of interest (e.g., a shaded area or multiple low-transparency markers), with the transparency or size of the marker correlating to the confidence score. The system continuously refines these POIs as more data streams in, demonstrating dynamic resolution of ambiguity.
• Combination Prior Art:
  1. This derivative combined with Apache Kafka for streaming data ingestion and Apache Flink for real-time stream processing of location text on a backend server, with results pushed to the mobile device.
  2. This derivative combined with SpaCy for open-source NLP entity recognition and Elasticsearch for fast, full-text search and spatial queries of historical location references.
  3. This derivative combined with Protobuf for efficient data serialization of ambiguous location predictions and Leaflet.js for rendering dynamic, confidence-weighted POIs on a web-based mapping interface accessible via the mobile device.

Derivative 10.3: Forensic Location Data Mapping for Digital Investigations

• Enabling Description: This derivative describes a specialized mobile forensic device designed for digital investigations. It receives location information from extracted digital artifacts (e.g., EXIF data from images, geo-tags from social media posts, GPS logs from vehicle telematics, Wi-Fi hotspot logs) obtained from a target device. The forensic application, acting as the external source, provides a structured export of this diverse data. The mobile forensic device's processing module then parses and normalizes this rich dataset, correlating timestamps and locations to reconstruct movement patterns. It filters out irrelevant data and resolves inconsistencies, generating a consolidated list of distinct location identifiers and their temporal context. These identifiers are then passed to a specialized mapping application on the forensic device. This mapping application not only plots the individual points of interest but also generates animated heatmaps showing "time spent" in an area, sequential paths, and spatio-temporal clusters, enabling investigators to visualize movements and significant locations over a specified period.
• Combination Prior Art:
  1. This derivative combined with GRASS GIS for robust geospatial data processing and analysis within the forensic application.
  2. This derivative combined with KML (Keyhole Markup Language) for standardized export and import of forensic location paths and points between different analysis tools.
  3. This derivative combined with SQLite for efficient on-device storage of parsed location artifacts and D3.js (or similar JavaScript library) for advanced, interactive spatio-temporal visualizations within the mapping application.

Derivative 10.4: Federated Learning for Crowd-Sourced POI Validation and Coordinate Refinement

• Enabling Description: This derivative details a system where a mobile device receives location information from an external source (e.g., a user submitting a new business address). This initial submission is considered unverified. The device processes this to extract the identifier. Before passing to the local mapping application, this identifier, along with locally derived contextual information (e.g., cell tower triangulation data, Wi-Fi SSIDs), is fed into a federated learning client. This client contributes to a global, decentralized model for POI validation and coordinate refinement. When other mobile devices, operating under the same federated learning scheme, encounter this same unverified POI or gather corroborating location data, their local models update and contribute to the global consensus. Once the federated model reaches a high confidence threshold for the POI's coordinates, the refined, validated coordinates are pushed back to the originating mobile device. The mapping application then displays this now-verified POI with higher confidence, potentially using a distinct visual indicator. This method continually improves mapping accuracy through collective intelligence without centralizing raw user location data.
• Combination Prior Art:
  1. This derivative combined with OpenStreetMap's crowd-sourcing methodology for geographic data collection and TensorFlow Federated for distributed machine learning model training.
  2. This derivative combined with GeoJSON for standardized representation of POI data and associated confidence scores during federated updates.
  3. This derivative combined with MQTT for lightweight communication between federated learning clients and a central orchestrator, and PostGIS for managing the validated geographic database on a federated server.

Derivative 10.5: Decentralized, User-Controlled Location Data Processing with Privacy-by-Design

• Enabling Description: This derivative focuses on a mobile device where all location information processing is executed locally and transparently, adhering to privacy-by-design principles. When the device receives location information from an external application, instead of immediately passing it to a centralized geocoding service, it first presents the raw input to the user for explicit permission to process. A user interface module, part of the mapping application, then allows the user to manually select privacy filters (e.g., "blur exact coordinates," "only show region," "anonymize source"). The device then performs local geocoding using an offline, open-source dataset (e.g., OpenStreetMap Nominatim data). If network assistance is required, the request is routed through a mix network (e.g., Tor) and only for privacy-preserving sub-queries. The derived (and potentially privacy-filtered) coordinates are then immediately displayed on the map. All intermediate processing steps are logged locally and are auditable by the user, and no raw location data is ever transmitted or stored off-device without explicit, granular user consent, enforced by cryptographic proofs.
• Combination Prior Art:
  1. This derivative combined with OpenStreetMap Nominatim for local, offline geocoding using open-source data.
  2. This derivative combined with Tor network client integration for anonymized network requests for supplementary geocoding data.
  3. This derivative combined with Decentralized Identifiers (DIDs) and Verifiable Credentials for user-controlled consent management and auditable privacy policies for location data sharing.

Independent Claim 16: Mobile device with mapping functionality

Core Claim Summary: A mobile electronic device equipped with a display, a processor, and memory. The device is configured to display a map with initial content from a mapping application. It also runs a non-mapping application capable of displaying mappable content. When the user selects this mappable content from the non-mapping application and issues a command, the device automatically displays the selected mappable content on the same map from the mapping application, in addition to the original map content.

---

Derivative 16.1: Ruggedized Modular Device for Expeditions and First Responders

• Enabling Description: This mobile electronic device is constructed with an MIL-STD-810G compliant, modular casing (e.g., reinforced carbon fiber composite) and an impact-resistant, transflective LCD display for readability in direct sunlight. Its processor is a low-power, fanless ARM-based SoC (e.g., NXP i.MX series), optimized for energy efficiency in remote operations, and features expanded non-volatile memory for offline map caching. The device includes a mapping application displaying initial content from pre-loaded topographic maps, satellite imagery, and critical infrastructure overlays. The modularity allows attachment of specific non-mapping application sensor modules (e.g., chemical hazard detector, advanced medical vital sign monitor, encrypted radio communication unit). When the user, via a large, gloved-hand friendly button or voice command, selects mappable data (e.g., "high radiation detected at [coordinates], source: Module 3") from the attached non-mapping sensor module, the device automatically presents the existing map. The detected hazard's location is overlaid as a color-coded icon (e.g., red for high radiation), with a dynamically expanding danger zone polygon, in addition to the original map content. The device's processor prioritizes rendering of critical hazard information and automatically adjusts the map extent and zoom to ensure the hazard and relevant escape routes are immediately visible.
• Combination Prior Art:
  1. This derivative combined with NATO's STANAG 4586 for UAV control protocols for integrating drone-collected hazard data from a modular sensor.
  2. This derivative combined with ESRI's ArcGIS Runtime SDK for robust offline map rendering and geospatial analysis capabilities on the mobile device.
  3. This derivative combined with MGRS (Military Grid Reference System) for standardized coordinate display and NMEA 0183 for communication with external GPS receivers and other navigation equipment.

Derivative 16.2: Low-Resource Offline Mapping on Legacy Devices

• Enabling Description: This derivative features an older generation mobile electronic device (e.g., pre-2010 smartphone) with limited processing power (e.g., single-core 600MHz CPU), small display (e.g., 3.5-inch resistive touchscreen), and restricted memory (e.g., 256MB RAM). The device is configured to display a highly optimized, vector-tile based map (e.g., using Mapbox GL JS with aggressive caching) with initial content from a lightweight mapping application designed for minimal resource consumption. A non-mapping application, such as a basic text editor or an RSS reader, runs in a background process with minimal overhead, displaying mappable content (e.g., "meet at library main entrance"). When the user selects this text (e.g., via a long-press context menu optimized for legacy touchscreens) and issues a mapping command, the device's processor intelligently manages memory and CPU cycles. It pauses non-critical background tasks, re-activates the mapping application, and displays the selected mappable content on the same map, generating a simple, low-polygon marker. Map rendering is simplified (e.g., no 3D elements, reduced detail levels), and zoom adjustments are pre-calculated to avoid real-time complex rendering, ensuring responsiveness despite hardware limitations.
• Combination Prior Art:
  1. This derivative combined with OpenStreetMap vector tiles for lightweight map data distribution and rendering.
  2. This derivative combined with Progressive Web App (PWA) architecture for the mapping application to enable offline functionality and minimal installation footprint.

• Enabling Description: This derivative is a mobile electronic device purpose-built as a tourism guide, featuring a high-resolution display with integrated augmented reality (AR) capabilities (e.g., LiDAR scanner, powerful GPU). The device runs a mapping application displaying an initial map of a historical district, highlighting key landmarks and walking paths. A non-mapping application, a "historical trivia" game or a "local recommendations" app, displays mappable content (e.g., "visit this hidden alley at [address] for local street art"). When the user, via a gesture (e.g., "pinch-to-map" on the touchscreen), selects this mappable content, the device automatically activates an AR overlay. The selected street art location is visually integrated as a dynamic waypoint projected onto the real-world view through the device's camera feed, aligning with the existing map content. The map application concurrently displays the location on its 2D map, and adjusts its zoom to show both the user's current position, the new point of interest, and relevant contextual information (e.g., historical markers) from the base map, providing an immersive, guided exploration experience.
• Combination Prior Art:
  1. This derivative combined with ARToolKit or ARCore/ARKit for augmented reality rendering and tracking.
  2. This derivative combined with GeoJSON for structured representation of tourist points of interest and street art locations.
  3. This derivative combined with OpenStreetMap data for base map information and OpenLayers for rendering the 2D map interface.

Derivative 16.4: AI-Powered Voice-Activated Mapping Device

• Enabling Description: A mobile electronic device features an array of high-fidelity microphones and a dedicated neural processing unit (NPU) for on-device AI inference. The device is configured to display an initial map in its mapping application. A non-mapping application, which could be an email client, a calendar, or a web browser, is capable of displaying mappable content. Instead of physical selection, the user issues a voice command, "Map the location mentioned in the last email." The device's NPU processes this command using a pre-trained speech-to-text model and an on-device NLP model (e.g., distilled BERT) to extract the location from the specified application. This extracted mappable content is then automatically fed to the mapping application, which intelligently displays it on the same map with the original content. The AI further optimizes the map presentation by inferring user intent from the voice command (e.g., "show me the fastest route," "display nearby restaurants") and automatically adjusting zoom, filters, and overlays.

Derivative 16.5: Limited-Scope "Zone Specific" Mapping Device

• Enabling Description: This mobile electronic device is configured to operate only within a predefined geographical zone (e.g., a specific industrial park, a campus, or a wildlife reserve). Its internal memory contains only the map data relevant to this zone, enforced by a geofencing module. The mapping application, therefore, always displays an initial map limited to this zone. A non-mapping application (e.g., asset tracking, personnel management within the zone) displays mappable content related to entities within this designated zone. When a user selects specific mappable content (e.g., "maintenance crew at Sector 4, Building B") and issues a command, the device automatically displays the selected mappable content on the same zone-specific map. The device prevents any map rendering or display functionality outside this predefined geofenced area, and any attempt to map an external location is met with a "location out of bounds" error, thereby limiting its functionality by design.
• Combination Prior Art:
  1. This derivative combined with GeoPackage (GPKG) for storing immutable, zone-specific map data offline.
  2. This derivative combined with MQTT for localized real-time updates of asset positions within the geofenced zone.
  3. This derivative combined with OSMAnd (OpenStreetMap for Android) for its ability to load and render custom, offline map packages.

Independent Claim 22: System for mapping and displaying location data

Core Claim Summary: A system that includes a first electronic device and a second electronic device (which may be the same as the first). The first device runs an application capable of displaying location information. When a user selects this location information, a mapping component receives it. This mapping component then transmits the location information to a mapping application on the second electronic device. The mapping application then displays a map showing the location information.

Derivative 22.1: Satellite-Integrated Decentralized Mesh Network for Disaster Response Mapping

• Enabling Description: This system comprises a first electronic device (a handheld field terminal for first responders) and a second electronic device (a command center console). The field terminal operates an application displaying real-time incident reports, including location information (e.g., "collapsed building at 34.0522 N, 118.2437 W"). When a first responder selects this location, an integrated mapping component on the terminal receives it. This component transmits the location information over a satellite-backhauled, decentralized mesh network (e.g., using LoRaWAN or Meshtastic protocols over Iridium SBD) to the command center console. The command center console, acting as the second device, receives this data. Its mapping application processes the satellite-derived location, correlates it with local ground truth data received from other mesh nodes, and displays a dynamically updated disaster area map, indicating the collapsed building. The system prioritizes low-bandwidth, robust communication for critical location updates in areas with compromised infrastructure.
• Combination Prior Art:
  1. This derivative combined with Meshtastic firmware for peer-to-peer mesh networking and OpenStreetMap for base map data.
  2. This derivative combined with MQTT-SN (MQTT for Sensor Networks) for constrained device communication over satellite links and GeoJSON for location data interchange.

Derivative 22.2: Global Real-time Mapping with Sub-Meter Precision via Hyper-Local Sensor Fusion

• Enabling Description: This system features a first electronic device (a mobile robot or autonomous vehicle) and a second electronic device (a cloud-based mapping platform accessed via any user device). The mobile robot, equipped with RTK-GPS, LiDAR, and high-resolution optical sensors, runs an application generating highly precise location-tagged data (e.g., "surface anomaly at [RTK-GPS coordinates] with 5cm deviation"). Upon detecting a significant anomaly, the robot's onboard mapping component automatically captures and transmits this sub-meter precise location information. This data is streamed via 5G to the cloud-based mapping platform. The cloud platform (second electronic device) fuses this real-time, precise data with other sensor inputs (e.g., atmospheric conditions from weather stations) to contextually enrich the anomaly. Its mapping application then displays a global map, dynamically zooming into the robot's location, showing the anomaly with its sub-meter precision and any fused environmental data, continuously updated as the robot moves.
• Combination Prior Art:
  1. This derivative combined with ROS (Robot Operating System) for robot sensor data integration and communication.
  2. This derivative combined with PostGIS for managing and querying high-precision geospatial data in the cloud-based mapping platform.
  3. This derivative combined with OGC Web Feature Service (WFS) for real-time querying of dynamically updated features and Mapbox GL JS for high-performance 3D map rendering in the web browser.

Derivative 22.3: Smart City Infrastructure Management with Digital Twin Integration

• Enabling Description: This system uses a first electronic device (a maintenance technician's smart glasses with integrated camera and AR capabilities) and a second electronic device (a central smart city operations dashboard). The smart glasses run an application that provides augmented reality overlays for infrastructure (e.g., highlighting underground pipes, electrical conduits). The technician visually identifies a problem (e.g., "leaking pipe segment ID #456 at intersection of Main St & Elm Ave") and, through gaze tracking or voice command, selects this location information within the smart glasses' AR interface. A mapping component embedded in the smart glasses transmits the precise location and asset ID to the central operations dashboard. The dashboard's mapping application, integrated with a digital twin of the city infrastructure, displays a 3D model of the city. It pinpoints the exact pipe segment, highlights its status (e.g., red for leak), and integrates real-time sensor data from the pipe, providing a comprehensive operational view for dispatching repair crews.
• Combination Prior Art:
  1. This derivative combined with glTF (GL Transmission Format) for efficient 3D model exchange between the smart glasses and the digital twin platform.
  2. This derivative combined with OPC UA (Open Platform Communications Unified Architecture) for standardized communication with industrial IoT sensors monitoring infrastructure.

Derivative 22.4: Blockchain-Verified Supply Chain Tracking System

• Enabling Description: This system involves a first electronic device (a smart tag or IoT sensor attached to a shipping container) and a second electronic device (a global supply chain monitoring platform accessible via web browser). The smart tag, running an application, periodically records its precise GPS location and environmental conditions (e.g., temperature, humidity). When a predefined event occurs (e.g., container door opened, temperature deviation), or at regular intervals, the smart tag's embedded mapping component signs the location information with its unique cryptographic key and commits it as an immutable transaction to a permissioned blockchain. The global supply chain monitoring platform (second electronic device) retrieves these verified location transactions from the blockchain. Its mapping application reconstructs the container's journey by displaying a map with a chain of verified, timestamped location points. Each point is associated with its cryptographic proof of authenticity and an audit trail, allowing stakeholders to verify the container's route and conditions transparently.
• Combination Prior Art:
  1. This derivative combined with Hyperledger Fabric for the permissioned blockchain network for supply chain transactions.
  2. This derivative combined with GeoJSON for standardized representation of location data within blockchain transactions.
  3. This derivative combined with MQTT for lightweight sensor data transmission from the smart tag to an initial gateway before blockchain commitment, and Leaflet.js for interactive map visualization.

Derivative 22.5: Redundant Backup Mapping System for Critical Infrastructure

• Enabling Description: This system consists of a primary electronic device (a critical infrastructure monitoring server) and a secondary, offline electronic device (a hardened, geographically distant backup server). The primary server runs an application that continuously displays the operational status and location of critical infrastructure assets (e.g., power grid nodes, water pipelines) on a high-resolution display. If the primary server detects a fault in an asset and the primary mapping component goes offline or fails, the system automatically triggers a failover. The primary server, before failure, transmits its last known state, including all displayed location information and active map layers, to the backup server via a dedicated, redundant link. The backup server, acting as the second device, initiates its own mapping application using this received data. It immediately displays a map of the critical infrastructure, showing the fault location and the last known operational status. This ensures continuous situational awareness even during a catastrophic primary system failure, operating in a 'recovery' mode that prioritizes data integrity and availability over real-time processing of new, incoming external data.
• Combination Prior Art:
  1. This derivative combined with MODBUS/TCP for communication with critical infrastructure control systems.
  2. This derivative combined with OGC GeoPackage (GPKG) for storing and exchanging the complete state of map data and layers during failover.
  3. This derivative combined with Zabbix for infrastructure monitoring and alerting the system to primary server failure.

Independent Claim 25: Method for selecting a map

Core Claim Summary: A method for a computing device to select a map for displaying new mapping data. After receiving the new mapping data and a command to map it, the method determines if a default map-display application has been designated. If so, the data is sent to that default application. If not, it checks for open map-display applications and, if found, selects one (e.g., the last used or one geographically closest to the mapping data) to display the new data, optionally setting it as the new default. If no applications are open, a new one is launched.

Derivative 25.1: Brain-Computer Interface (BCI) driven Map Selection

• Enabling Description: This derivative describes a computing device integrated with a non-invasive Brain-Computer Interface (BCI) (e.g., EEG headset). The device receives new mapping data (e.g., a meeting address from a calendar application) and a command to map it, which can also be issued via BCI (e.g., a specific thought pattern recognized by the BCI). The system first checks for a default map-display application designated by the user's implicit BCI training data (e.g., an application frequently activated when thinking "map work locations"). If a default is recognized, the data is sent there. If not, the BCI monitors the user's cognitive response (e.g., alpha wave patterns, attention spikes) as a dynamically generated list of open map-display applications (or suggested new ones) is briefly displayed. The application eliciting the strongest "interest" or "recognition" signal from the BCI is automatically selected to display the new mapping data, and optionally set as the new BCI-inferred default. If no BCI-driven preference is detected or no applications are open, a new instance of a system-defined default mapping application is launched.
• Combination Prior Art:
  1. This derivative combined with OpenBCI GUI and API for real-time EEG data acquisition and processing.
  2. This derivative combined with OpenStreetMap Nominatim for reverse geocoding to quickly determine the geographic relevance of map suggestions.
  3. This derivative combined with Electron framework for developing cross-platform desktop map-display applications that can interface with BCI data streams.

Derivative 25.2: Multi-Dimensional Data Map Selection for Geospatial Simulation

• Enabling Description: This derivative describes a computing device used for advanced geospatial simulations (e.g., climate modeling, urban growth projections), which receives complex new mapping data, including not only geographic coordinates but also time-series data (e.g., temperature over decades) and volumetric data (e.g., atmospheric pollutant concentrations at different altitudes). Upon a command to map this data, the system evaluates available map-display applications. Instead of simple geographic proximity, it employs a multi-criteria optimization algorithm. This algorithm considers the map's native dimensionality (2D, 3D), its ability to render time-series animations, its support for volumetric data visualization, and its thematic relevance to the new data (e.g., a climate modeling application for temperature data). The map-display application that best matches the multi-dimensional attributes of the new data, minimizing data transformation requirements and maximizing visualization fidelity, is automatically selected. This selection might prioritize an application that can display a 4D (3D + time) map over a simpler 2D map, even if the 2D map is geographically closer.
• Combination Prior Art:
  1. This derivative combined with Open Geospatial Consortium (OGC) standards (e.g., WCS for Coverage data, WKT for geometry) for handling complex geospatial data types.
  2. This derivative combined with NASA WorldWind or CesiumJS for powerful 3D globe visualization and time-series animation capabilities.
  3. This derivative combined with NetCDF (Network Common Data Form) for storing multi-dimensional scientific data (e.g., climate model outputs).

Derivative 25.3: Medical Imaging Analysis with Anatomical Map Selection

• Enabling Description: This derivative is for a computing device in a medical context, receiving new imaging data (e.g., a detected lesion at specific anatomical coordinates within the brain, derived from an MRI scan). The command to map this data is issued by a clinician. The method determines if a default anatomical map-display application (e.g., a specialized neuro-imaging viewer) has been designated. If so, the lesion data is sent to that application. If not, it checks for open anatomical map-display applications (e.g., different brain atlas viewers, 3D anatomical models). The selection algorithm prioritizes an application that already displays a relevant anatomical region (e.g., the specific lobe of the brain) and can effectively render the lesion with appropriate medical overlays. It would favor a map-display application that matches the modality and resolution of the incoming data, and can display the new data in a 3D context with relevant anatomical landmarks, rather than a generic 2D map.
• Combination Prior Art:
  1. This derivative combined with DICOM (Digital Imaging and Communications in Medicine) standard for medical image data.
  2. This derivative combined with 3D Slicer or ITK-SNAP for open-source medical image visualization and analysis.
  3. This derivative combined with NIfTI (Neuroimaging Informatics Technology Initiative) format for brain imaging data.

Derivative 25.4: Reinforcement Learning (RL) for Personalized Map Recommendations

• Enabling Description: This derivative describes a computing device that, after receiving new mapping data and a command, uses a Reinforcement Learning (RL) agent to select the optimal map. Initially, the system might follow predefined rules (default, last used, closest geography). However, the RL agent (e.g., using Q-learning or Deep Q-Networks) continuously observes user interactions with selected maps (e.g., how long they spend on a map, if they zoom/pan, if they immediately switch apps after map display). Based on these observations, the RL agent learns a personalized policy. When new mapping data arrives, the RL agent, acting as the map selection logic, predicts which available map-display application (or new instance thereof) is most likely to satisfy the user's implicit needs and preferences for that specific type of mapping data. Over time, the system learns to select the "best" map, dynamically adapting to evolving user behavior without explicit configuration. The "reward" signal for the RL agent is derived from positive user engagement metrics with the displayed map.
• Combination Prior Art:
  1. This derivative combined with OpenAI Gym for designing the reinforcement learning environment for map selection.
  2. This derivative combined with Google's Protocol Buffers (Protobuf) for efficient data exchange of user interaction logs for RL training.
  3. This derivative combined with Leaflet.js for building customizable and extensible web-based map applications whose interaction data can be easily captured for RL feedback.

Derivative 25.5: "Least Data Exposure" Map Selection for Sensitive Information

• Enabling Description: This derivative describes a computing device designed for handling sensitive mapping data, where the primary objective is to minimize exposure of that data. When the device receives new mapping data (e.g., classified facility location) and a command to map it, the system first determines if a default map-display application has been designated that adheres to stringent data handling protocols (e.g., isolated network segment, air-gapped display). If so, the data is transmitted there. If not, it checks for open map-display applications and evaluates them against predefined security and privacy criteria, such as network connectivity status (offline preferred), data logging policies, and access controls. The system selects the map-display application that offers the "least data exposure" profile (e.g., an offline, sandboxed mapping application that does not log coordinates, even if it requires more panning than a geographically closer, but internet-connected, option). If no applications meet the minimum security threshold or none are open, a specialized, disposable, temporary "secure viewer" is launched, which automatically purges all map data upon closing.
• Combination Prior Art:
  1. This derivative combined with SELinux/AppArmor for mandatory access control policies to sandbox map-display applications.
  2. This derivative combined with Zero-knowledge Proof (ZKP) protocols to verify map data origins and integrity without revealing the underlying sensitive information.
