US 10444943

US Patent 10444943, titled "Interactive electronically presented map," was issued to Activemap LLC on October 15, 2019, from an application filed on February 10, 2017. The inventors listed are Michael Abramson, Erika Jakubassa, Michael Grisham, and Geoff Atkin.

Abstract:
The patent describes computerized systems and methods for providing an electronically presented interactive area representation, such as a map, along with associated information. A user can select text, imagery, or other information on the map linked to specific items or locations. This selection triggers the presentation of related information, such as contact details or a hyperlink to a website. Conversely, a user can input a query or select information pertaining to items or locations, which then causes the system to indicate their positions on the map. The invention also features a "magnifier" for internal map navigation and the ability to display animated images that move across the map.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Computer-Implemented Method):
  This claim describes a method where a computer displays an unmagnified electronic map with associated information at various locations. It simultaneously displays a highlighted portion of this unmagnified map and a magnified view of that highlighted portion. A user can smoothly move the highlighted portion across the unmagnified map using an input device, and the magnified view will smoothly update to reflect the new highlighted area. The method further allows a user to select information from the magnified view, causing the display of additional details (like contact information or a web link). Conversely, if a user inputs or selects specific item information, the system will indicate that item's location on the unmagnified map and reposition the highlighted portion and magnified view to that location.

• Independent Claim 7 (System):
  This claim defines a computer system comprising a display device, an input device, and a processing unit. The processing unit is configured to perform the actions outlined in Claim 1. Specifically, it displays both an unmagnified electronic map (with associated item information) and a highlighted portion, along with a magnified view of the highlighted portion. The system enables the highlighted portion and magnified view to be smoothly moved and updated in response to user input. It also facilitates displaying additional item information upon selection from the magnified view, and conversely, moving the highlighted portion and magnified view to a location corresponding to user-input item information.

• Independent Claim 14 (Computer Program Product):
  This claim covers a computer program stored on a non-transitory computer-readable medium. When a computer executes this program, it causes the computer to perform the same method steps detailed in Independent Claim 1. This includes displaying interactive maps with unmagnified and magnified views, allowing smooth navigation via a highlighted portion, and providing two-way interaction between map locations/features and associated textual or multimedia information.

The initial instruction states "The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest." My web search also did not directly yield any PTAB trial proceedings (IPR, PGR, CBM) for US10444943. The search results discuss the patent in the context of litigation in Texas Eastern District Court (which was already known from the previous prompt), and licensing agreements in Germany. Activemap LLC's own website lists US10444943 as one of its patents but does not mention any PTAB challenges. There are general links to PTAB search functions, but no specific results for this patent.

Therefore, I have confirmed that there are no PTAB proceedings on file for US10444943 based on the provided information and web search.

Proceedings overview

There are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method) on file for US Patent 10444943. This means that the patent claims have not been challenged in an AIA trial before the Patent Trial and Appeal Board (PTAB).

Strategic summary

As of the current date, US Patent 10444943 has not been subjected to any AIA trial proceedings before the PTAB. This implies that all claims of the patent (claims 1-14) remain untested by this specific administrative challenge mechanism. For a defendant facing assertion of this patent, this means there is no existing PTAB record of claims being canceled, sustained, or narrowed, which could otherwise inform a defense strategy.

The absence of PTAB proceedings also indicates that no prior art grounds (under 35 U.S.C. §§ 102 or 103 for IPRs, or additional grounds for PGR/CBM) have been formally litigated and decided by the Board for this patent. Consequently, there is no estoppel against potential petitioners (or their privies) under 35 U.S.C. § 315(e)(2) for any prior art grounds that could have been raised. This leaves the full range of PTAB challenge options open to a new petitioner.

Recommended next steps

• If you are a defendant facing an assertion of US10444943, the absence of PTAB activity means that all claims are currently presumed valid as granted by the USPTO, without any PTAB-issued invalidity findings. An IPR, PGR, or CBM petition remains a viable defensive option to challenge the patent's validity based on prior art.
• Given the ongoing district court litigation in the Texas Eastern District Court, considering a PTAB challenge could be a strategic move to address validity outside of district court.
• Before filing a petition, a thorough prior art search would be crucial to identify strong grounds for challenging the patent's claims, especially since they have not been previously tested in AIA trials.
• If you are the patent owner (Activemap LLC), the lack of PTAB challenges to date could be seen as a positive, as the claims remain intact. However, in light of the district court litigation, it is prudent to be prepared for potential PTAB petitions from defendants seeking to invalidate claims. Robust claim construction and prior art analysis are essential to defend against such future challenges.

Inventors

• Michael Abramson: Employer at time of filing (2017-02-10) is not determinable from the patent document.
• Erika Jakubassa: Employer at time of filing (2017-02-10) is not determinable from the patent document.
• Michael Grisham: Employer at time of filing (2017-02-10) is not determinable from the patent document.
• Geoff Atkin: Employer at time of filing (2017-02-10) is not determinable from the patent document.

The patent document states that the application was filed by Activemap LLC on 2017-02-10, and also that the inventors assigned their interest to ACTIVEMAP LLC on 2017-02-20. This suggests the inventors were likely associated with Activemap LLC at the time of filing, but direct employer information is not explicitly stated.

Original assignee

The original assignee, as listed on the issued patent US10444943B2, is Activemap LLC.

Determining if Activemap LLC shipped a product embodying the claims, their primary line of business, and their current status requires external research.

Activemap LLC was founded in the early 2000s by the inventors of the patent. Their primary line of business is patent licensing, specifically related to interactive electronic maps and foundational "store locator website functionality". The company itself does not appear to directly ship a product, but rather licenses its intellectual property. They have partnered with Vectis IP Ltd, a UK-based IP and technology licensing company, to lead a global licensing program. Activemap LLC and Activemap Europe GmbH are proudly run by the original inventors.

Activemap's technology has diverse applications including city and neighborhood maps, museums, zoos, theme parks, real estate offerings, venues, and technical diagrams. While there are references to "ActiveMap" as a field service management software, this appears to be a different entity (activemap.me) and not directly related to Activemap LLC (activemapllc.com), the patent assignee.

As of the current date, Activemap LLC appears to be an active entity, engaged in patent licensing and enforcement activities, including litigation in the Texas Eastern District Court.

Assignment timeline

No assignments for US10444943 are found on the USPTO Assignment Center (https://assignmentcenter.uspto.gov/) other than the initial assignment from the inventors to Activemap LLC. The patent itself notes an assignment to ACTIVEMAP LLC on 2017-02-20.

• 2017-02-20 (executed) / recorded 2017-02-20 (per patent details, not Assignment Center)
  • Conveyance: Assignment of Assignors Interest
  • Assignor: Michael Abramson, Erika Jakubassa, Michael Grisham, Geoff Atkin
  • Assignee: ACTIVEMAP LLC
  • Correspondent: Not specified in patent metadata for this event.
  • Context: Original assignment from inventors to the founding entity.

Since the USPTO Assignment Center search yields no additional results for patent number 10444943, this indicates that Activemap LLC remains the current assignee of record through the USPTO's assignment database.

NPE / troll-pattern signals

1. Shell-entity transfer — Not present. There are no recorded transfers from an operating company to a licensing-only LLC in the USPTO assignment records. Activemap LLC itself appears to be a licensing entity, but it is the original assignee directly from the inventors.
2. Known asserter in the chain — Not present. Activemap LLC is not explicitly listed as a high-frequency plaintiff on public NPE lists like RPX or Unified Patents (based on available search results). However, they are actively engaged in licensing and litigation.
3. Repeat correspondent across the chain — Not present. Only the initial assignment from inventors to Activemap LLC is readily available in the patent's legal event history, which doesn't specify a correspondent. No subsequent assignments are recorded via the USPTO Assignment Center to establish a pattern.
4. Cascading transfers — Not present. No multiple consecutive assignments through chained LLCs are recorded in the USPTO assignment records.
5. Pre-litigation transfer — Not present. The patent was issued to Activemap LLC in October 2019. Litigation began in February 2026. There is no recorded assignment within 6 months of the first infringement suit.
6. Bankruptcy fire-sale — Not present. There is no indication in the patent information or general search results that Activemap LLC or its predecessors underwent bankruptcy and sold patents in proceedings.
7. Privateering — Unclear. While Activemap LLC primarily licenses its patent portfolio, there's no explicit public evidence (e.g., SEC filings from a larger operating company, or specific investigative reporting) to suggest they are asserting on behalf of an operating company against its competitors.
8. Defensive aggregator (anti-NPE) — Not present. The chain does not end at a defensive aggregator. Activemap LLC is actively asserting the patent.

Verdict

NPE — moderate confidence

Activemap LLC, the original and current assignee, was founded by the inventors with a business model focused on licensing their patent portfolio rather than direct product sales. The patent family is currently involved in multiple infringement lawsuits filed in the Texas Eastern District Court in 2026, indicating an active assertion strategy. While there are no shell-entity transfers within the assignment chain or evidence of repeat NPE correspondents, the business model and active litigation are strong indicators of a licensing-focused entity.

The abstract aligns with the previous summary, detailing computerized systems and methods for interactive electronic map presentation with associated information, a magnifier feature, and animated images.

Prior Art References and Potential Anticipation

The patent document for US10444943 lists the following prior art. I will analyze these in detail.

U.S. Patent No. 4,974,170

• Full Citation: U.S. Pat. No. 4,974,170, "Vehicle navigation system having map display with position indicator," issued to O'Sullivan et al.
• Publication/Filing Date: The patent was granted on December 4, 1990. The filing date is November 17, 1987.
• Brief Description: This patent describes a vehicle navigation system that displays a map with a current vehicle position indicator. It allows for map scaling and scrolling to keep the vehicle centered on the display.
• Potential Anticipation (35 U.S.C. § 102): This patent potentially anticipates aspects of Claim 1, 7, and 14 related to displaying an electronic map with a position indicator and enabling movement of the map/indicator. However, it does not explicitly disclose the "magnifier" feature with a simultaneous magnified view or the two-way interaction between item information and map location as detailed in US10444943.

U.S. Patent No. 5,682,525

• Full Citation: U.S. Pat. No. 5,682,525, "Geographic information system with data access through map objects," issued to Tanaka et al.
• Publication/Filing Date: The patent was granted on October 28, 1997. The filing date is September 29, 1995.
• Brief Description: This patent discloses a geographic information system where map objects (e.g., buildings, roads) can be selected to access associated information. It focuses on the interactive retrieval of data linked to geographical features.
• Potential Anticipation (35 U.S.C. § 102): This patent could potentially anticipate elements of Claim 1, 7, and 14 concerning the selection of information on a map to cause presentation of associated details. However, it does not clearly describe the dynamic, smoothly moving magnifier with a simultaneous magnified view as a core aspect of its interaction.

U.S. Patent No. 6,148,260

• Full Citation: U.S. Pat. No. 6,148,260, "Navigation system and method for displaying points of interest and advertising information," issued to Tamai et al.
• Publication/Filing Date: The patent was granted on November 14, 2000. The filing date is June 16, 1998.
• Brief Description: This patent describes a navigation system that displays points of interest and can present advertising information related to those points. It focuses on integrating commercial information with navigation.
• Potential Anticipation (35 U.S.C. § 102): This patent might anticipate parts of Claim 1, 7, and 14 related to displaying associated information (which could include advertising) linked to locations on a map. However, the unique interactive features of the magnifier and two-way information access, particularly the smooth, simultaneous magnified view, are not explicitly described in this prior art.

U.S. Patent No. 5,818,455

• Full Citation: U.S. Pat. No. 5,818,455, "Zooming user interface for displaying spatial information," issued to Cooper et al.
• Publication/Filing Date: The patent was granted on October 6, 1998. The filing date is February 10, 1997.
• Brief Description: This patent describes a zooming user interface for displaying spatial information, which could include maps, where a portion of the display can be magnified. It focuses on techniques for navigating through different levels of detail.
• Potential Anticipation (35 U.S.C. § 102): This patent is particularly relevant to the "magnifier" feature of US10444943. It could potentially anticipate the concept of displaying a magnified portion of a map. However, a key distinction for US10444943's claims (Claim 1, 7, and 14) lies in the smooth and continuous movement of a highlighted portion on an unmagnified map causing a simultaneous smooth update of a distinct magnified view, and the explicit two-way interaction with item information via this dynamic magnifier. The '455 patent may describe zooming generally, but not necessarily the specific interactive mechanism of the "magnifier" as claimed.

U.S. Patent No. 4,800,379

• Full Citation: U.S. Pat. No. 4,800,379, "Electronic magnifying glass," issued to Takeda.
• Publication/Filing Date: The patent was granted on January 24, 1989. The filing date is December 11, 1986.
• Brief Description: This patent describes an electronic magnifying glass for displaying an enlarged image of a selected portion of a larger image on a display screen.
• Potential Anticipation (35 U.S.C. § 102): Similar to US 5,818,455, this patent is relevant to the "magnifier" feature. It generally anticipates the idea of an "electronic magnifying glass" to enlarge a portion of an image. However, for Claim 1, 7, and 14 of US10444943, the critical elements of interaction (smooth movement, simultaneous update of a distinct magnified view, and explicit two-way linking with external item information) would need to be present and explicitly described in the '379 patent to constitute a complete anticipation. Without these specific interactive functionalities in the context of maps and associated information, it would likely serve as a foundational concept rather than a direct anticipation of the full scope of the claims.

Obviousness Analysis of US Patent 10444943 Under 35 U.S.C. § 103

The independent claims of US Patent 10444943 relate to an interactive electronically presented map system featuring an unmagnified view, a smoothly movable highlighted portion, a corresponding smoothly updating magnified view, and two-way interactivity between map locations and associated information. A person having ordinary skill in the art (PHOSITA) in 2001 (the priority date of April 30, 2001) would have found the claimed invention obvious through combinations of existing prior art references and common general knowledge.

Identified Prior Art References:

The patent itself identifies several relevant prior art references in its background section and description:

1. Online Interactive Map Services: Websites such as MapQuest.com, www.mapsonus.com, www.maps.expedia.com, www.maps.yahoo.com, www.maps.com, www.maps.excite.com, www.mapblast.com, and www.zip2.com.
2. US Pat. No. 6,148,260: An "Interactive network directory service with integrated maps and directions" (filed 1999, granted 2000), which integrates a business directory with a map database.
3. US Pat. No. 5,818,455: Discloses "a magnifier feature that facilitates use of an electronically presented map."
4. US Pat. No. 4,800,379: Discloses "use of a magnifier in connection with display of an image."
5. General Computer Graphics and Web Development Tools: Specifically, the patent US10444943 mentions implementing its features using a "Shockwave executable application" and "Macromedia Director." Macromedia Director 8.5 Shockwave Studio was released in April 2001, just before the priority date, and was a well-known tool for creating interactive web content with animation.

Obviousness Combinations and Motivation to Combine:

The independent claims (Claims 1, 7, and 14) of US10444943 would have been obvious to a PHOSITA in 2001 by combining the following prior art elements:

1. Basic Interactive Map with Magnifier and Two-Way Interactivity:

• Foundation: The core concept of an "unmagnified electronic area representation of an area having item information at a plurality of locations" was widely available through online map services like MapQuest.com (launched 1996) and Yahoo Maps (launched circa 1998). These services allowed users to view maps, see associated points of interest or businesses (item information), search for specific locations or businesses, and display those results on the map. Similarly, US Pat. No. 6,148,260 explicitly teaches a network service integrating a business directory and map database, enabling users to search for businesses and get directions displayed on a map.
• Magnifier Feature: The addition of a "magnifier feature" to an electronic map was directly taught by US Pat. No. 5,818,455, which disclosed such a feature specifically for "electronically presented maps." Further, US Pat. No. 4,800,379 provided general teaching of a magnifier for image display.
• Motivation to Combine (Interactive Maps + Magnifier): A PHOSITA would have been motivated to combine the known functionality of interactive online maps (e.g., displaying an unmagnified map, showing item information, searching for locations) with the "magnifier feature" taught by US Pat. No. 5,818,455. The motivation would be to enhance user experience by allowing detailed exploration of specific map portions without losing the context of the larger map, a common desire for improving usability of digital interfaces.

2. Enhancing the Magnifier with Smooth Movement and Comprehensive Two-Way Interaction:

• Smooth Movement and Updating: Once the magnifier feature (from US Pat. No. 5,818,455) was applied to an interactive map (from MapQuest/US Pat. No. 6,148,260), the "smoothly move" and "smoothly changing" aspects of the magnifier and its magnified representation would be an obvious design choice for a PHOSITA. In 2001, tools like Macromedia Director 8.5 Shockwave Studio were readily available and widely used for creating dynamic, animated, and interactive content on the web. A PHOSITA would naturally employ such known animation and graphical rendering techniques to ensure that the interactive elements of a user interface, such as a movable magnifier, provided a fluid and responsive user experience. The patent itself explicitly describes using "scripts" and a "Shockwave executable application" for this purpose.
• Comprehensive Two-Way Interactivity (Selection from Magnified View & Positioning Magnifier from Input):
  • Selection from Magnified View: Online map services like MapQuest.com already provided functionality where users could click on a location on an unmagnified map to display additional information, such as contact details or a hyperlink to a website. It would be an obvious extension for a PHOSITA to apply this existing interactive paradigm to information displayed within the magnified representation (derived from US Pat. No. 5,818,455). If a user is viewing a magnified portion of a map, they would logically expect to be able to interact with and retrieve information about elements within that magnified view, just as they could on the overall map.
  • Positioning Magnifier from Input: Similarly, existing online map services (MapQuest.com, Yahoo Maps, and US Pat. No. 6,148,260) allowed users to input or search for item information (e.g., a business name or address) and have the system display an "indication of a location" of that item on the unmagnified map. It would be an obvious integration for a PHOSITA to combine this search-and-locate functionality with the magnifier feature (from US Pat. No. 5,818,455). The motivation would be to enhance user convenience by automatically positioning the highlighted portion and its corresponding magnified view directly over the location identified by the user's search, thereby focusing their attention on the relevant detailed area.

Conclusion:

The independent claims of US10444943 describe a combination of features that were individually known in the prior art or would have been obvious improvements to known systems by a PHOSITA at the time of the invention. The use of interactive online maps with associated data was prevalent (e.g., MapQuest.com, US Pat. No. 6,148,260). Magnifier features on electronic displays, including maps, were also known (US Pat. Nos. 5,818,455 and 4,800,379). The "smooth" dynamic updating of graphical elements was a common design goal in user interfaces, achievable with standard web development tools like Macromedia Director/Shockwave. Finally, the two-way interaction between map features and associated information was a fundamental aspect of interactive map services.

A PHOSITA would have been motivated to combine these known elements to create a more efficient, user-friendly, and engaging interactive map experience, driven by the desire for improved usability, enhanced functionality, and the availability of suitable technological tools. Therefore, the claimed invention, as described in independent claims 1, 7, and 14, would have been obvious under 35 U.S.C. § 103.

US Patent 10444943: Term Adjustments, Extensions, and Family Members

Patent Term Adjustment (PTA):
Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. This adds time to the standard 20-year patent term from the earliest filing date. Common reasons for PTA include:

• Failure to issue an office action or notice of allowance within 14 months of filing.
• Failure to respond to an applicant's reply within four months.
• Failure to issue a patent within four months of payment of the issue fee.
• Failure to issue a patent within three years of the actual filing date.

The USPTO automatically calculates and provides notice of the PTA on or before the patent's issuance date. The patent document for US10444943 should contain the specific PTA awarded, if any. Without direct access to the issue notification or the USPTO's Patent Center for this specific patent, the exact PTA amount cannot be definitively stated at this time.

Patent Term Extension (PTE):
Patent Term Extension (PTE) is available under the Hatch-Waxman Act (35 U.S.C. § 156) for patents claiming products, methods of use, or manufacturing processes that require pre-market regulatory approval (e.g., human and veterinary pharmaceuticals, food additives, medical devices). PTE aims to restore a portion of the patent term lost during the regulatory review period. Key requirements for PTE include:

• The patent must not have expired.
• The patent term must not have been previously extended.
• The application must be submitted by the patent owner or agent within 60 days of regulatory approval.
• The product must have undergone a regulatory review period before commercial marketing or use.

Given that US10444943 is titled "Interactive electronically presented map," it is highly unlikely to be eligible for Patent Term Extension as it does not appear to cover a product requiring regulatory approval under 35 U.S.C. § 156.

Another priority is listed for US16/516,215 (US10908782B2), filed July 18, 2019, which indicates this patent is also a family member.

Projected Expiration Date:
The patent information states an "Anticipated expiration" date of April 30, 2022. It also notes the "Legal status" as "Expired - Fee Related," and "Current" status as "Expired - Fee Related."

Considering the original priority date of April 30, 2001 (from provisional application No. 60/287,339), a typical patent term is 20 years from the earliest non-provisional filing date. If the earliest non-provisional filing date was April 30, 2002 (US 10/136,845), then the unadjusted 20-year term would end on April 30, 2022. This aligns with the "Anticipated expiration" date provided in the patent information.

Given the "Expired - Fee Related" status, it appears the patent has indeed expired as of April 30, 2022, likely due to a failure to pay maintenance fees.

1. Material & Component Substitution

This section details variations involving alternative materials and mechanical/electronic components for implementing the interactive map system.

Derivative 1.1: Flexible Organic Light-Emitting Diode (OLED) Display with Haptic Feedback and Electroluminescent Highlight

Enabling Description:
An interactive electronic map system utilizes a flexible OLED display panel (e.g., using polyimide substrates and solution-processed emissive layers) as the unmagnified map display. The highlighted portion is rendered via an embedded, dynamically addressable electroluminescent polymer layer that changes luminescence intensity and color (e.g., yellow phosphorescent dopants) when electrically excited, creating a visually distinct boundary or fill. User interaction for smooth movement is achieved via an integrated haptic feedback array (e.g., piezoelectric actuators or vibrotactile motors) beneath the flexible display surface, providing tactile cues as the user's finger (serving as the input device) traverses map features. The magnified view is displayed on a separate, rigid micro-LED display with ultra-high pixel density (>1000 PPI) and a transparent capacitive touch overlay for precise information selection. Data transmission employs a low-latency, high-bandwidth optical fiber network using 100 Gigabit Ethernet (100GbE) for real-time updates.

Derivative 1.2: E-Ink Display Array with Electro-Fluidic Magnifier and Ultrasonic Gesture Control

Enabling Description:
The unmagnified electronic map is presented on a large-format tiled array of monochrome or multi-color E-Ink display modules (e.g., electrophoretic microcapsule technology), offering persistent display with minimal power consumption. The "magnifier" is implemented as a mobile, transparent electro-fluidic lens overlay, where localized electric fields manipulate a refractive liquid (e.g., silicon oil with embedded nanoparticles) to create a variable focal length optical magnification directly above the E-Ink surface. The highlighted portion is defined by the physical boundary of this fluidic lens. User input for smooth movement of the lens is achieved through an array of ultrasonic transceivers (e.g., time-of-flight sensors operating at 40 kHz) that detect precise 3D hand gestures above the E-Ink array, allowing non-contact manipulation. Information associated with the magnified view is rendered on a secondary, high-refresh-rate LCD panel, triggered by a specific "pinch" gesture detected by the ultrasonic array when hovering over a point of interest.

Derivative 1.3: Ferrofluidic Topography Map with Magnetic Stylus and Photonic Crystal Magnifier

Enabling Description:
A physically reconfigurable map surface is created using a ferrofluid contained within a matrix of addressable electromagnets. The unmagnified map is displayed by varying the magnetic field strength to create topographical relief patterns corresponding to geographical features (e.g., mountains, rivers). Item information locations are represented by embedded, individually addressable micro-LEDs within the ferrofluidic matrix. User interaction for defining and moving the highlighted portion is performed with a magnetic stylus that senses local magnetic field gradients and provides haptic feedback. The "magnified view" is generated by a portable photonic crystal lens, which when placed above the ferrofluid, optically magnifies the underlying relief and activates a corresponding subset of micro-LEDs to display granular item information. The magnified information is captured by a miniature camera integrated into the photonic crystal lens, processed, and displayed on a wearable micro-display (e.g., waveguide display glasses).

    E -- Data Processing --> F(Processing Unit)
    F -- Control Signals --> B

Derivative 1.4: Multi-Layer Transparent LCD with Infrared Touch and Dynamic Lightfield Magnification

Enabling Description:
The unmagnified map is presented across a stack of transparent liquid crystal displays (LCDs), allowing for depth perception and overlaying different map data layers (e.g., terrain, utilities, property lines). User interaction for defining the highlighted portion occurs via an integrated infrared (IR) multi-touch sensor grid within the top LCD layer. The "magnified view" is achieved through dynamic lightfield display technology, where a region of the transparent LCD stack selectively renders a magnified, parallax-aware view by controlling individual light rays, giving the impression of a holographic magnifier floating above the surface. Movement of the highlighted area by user touch smoothly updates this lightfield magnification. Item information (e.g., 3D models of buildings, utility schematics) is streamed in real-time from a cloud-based geospatial database (e.g., using OGC CDB standard) and rendered within the lightfield, allowing for interactive manipulation through IR touch gestures.

2. Operational Parameter Expansion

This section describes variations where the interactive map technology operates at extreme scales or conditions.

Derivative 2.1: Nanoscale Molecular Map with Electron Beam Magnifier for Chemical Synthesis Guidance

Enabling Description:
An unmagnified map represents a 2D projection of molecular structures or a reaction pathway on a substrate at the nanoscale (e.g., 10 nm scale). Item information includes atomic species, bond types, or active sites, visualized as color-coded regions. A focused electron beam (e.g., from a scanning electron microscope modified for interaction) acts as the position indicator, raster-scanning a highlighted portion. The "magnified view" is generated by increasing the electron beam dwell time and resolution over the highlighted area, achieving up to 1,000,000x effective magnification, revealing individual atoms and their orbitals. User input for moving the electron beam is achieved through a haptic joystick interface connected to piezoelectric stage actuators with sub-nanometer precision. Selection of molecular features in the magnified view triggers display of quantum chemical properties (e.g., HOMO/LUMO orbitals, bond energies) via a computational chemistry backend, which can then guide automated atomic force microscopy (AFM) manipulation or electron-beam lithography for direct chemical synthesis.

Derivative 2.2: Planetary-Scale Dynamic Weather Map with Global Telemetry and Adaptive Resolution Magnifier

Enabling Description:
The unmagnified electronic map displays real-time weather patterns across an entire planetary body (e.g., Earth, Mars) at a global scale (e.g., 1:100,000,000 resolution), with item information representing atmospheric pressure, temperature, wind vectors, and precipitation derived from a network of orbital satellites and ground-based IoT telemetry stations. The system handles petabytes of data updated every minute. The "highlighted portion" is a user-defined region (e.g., a hurricane path) that dynamically adapts its resolution based on meteorological significance. The "magnified view" provides localized weather forecasts down to a 1:1,000 resolution, leveraging an adaptive mesh refinement (AMR) algorithm to increase computational and display resolution only within the highlighted area, processing data from high-resolution radar and ground sensors. User input for defining and moving the highlighted region is managed by a geographically distributed network of meteorologists using collaborative virtual reality (VR) interfaces, where haptic gloves simulate atmospheric conditions.

Derivative 2.3: Ultra-High Frequency Spectral Map with Hyperspectral Magnifier for RF Interference Localization

Enabling Description:
An unmagnified electronic map visualizes the radio frequency (RF) spectrum (e.g., 0 Hz to 3 THz) across multiple dimensions (frequency, power, time, spatial origin) as a dynamic heatmap. Item information denotes active transmitters, interference sources, or unoccupied bandwidth, represented by color and intensity. The "highlighted portion" is a user-selected frequency band or geographic area of interest within the spectrum, defined by a directional antenna array and a high-speed field-programmable gate array (FPGA) for real-time spectral analysis. The "magnified view" provides a hyperspectral analysis of the highlighted RF signal, breaking it down into minute frequency sub-bands (e.g., 1 Hz resolution) and identifying modulation schemes, signal characteristics, and precise geolocation of interference sources using advanced triangulation algorithms. User input is provided via a gestural control system interpreted by a quantum processor for rapid pattern recognition in high-dimensional spectral data, allowing fluid navigation through complex RF environments.

3. Cross-Domain Application

This section illustrates the application of the core interactive map mechanism in three unrelated industries.

Derivative 3.1: Aerospace - Dynamic Airspace Management and Drone Fleet Command

Enabling Description:
An unmagnified electronic map displays a three-dimensional representation of controlled airspace, with item information representing aircraft, flight paths, weather systems, and restricted zones. For drone fleet management, it tracks individual drones, their mission parameters, battery status, and sensor feeds. A highlighted portion is dynamically drawn around a specific region of airspace (e.g., airport approach, drone delivery corridor) or a cluster of aircraft. The magnified view provides granular detail for that region, showing individual aircraft identification, altitude, speed, predicted trajectory, and real-time telemetry from transponders (e.g., ADS-B data for manned aircraft, custom drone telemetry protocols). User input via a multi-modal interface (voice commands for high-level tasks, haptic joystick for precise control) allows air traffic controllers or drone operators to smoothly navigate the airspace, identify potential conflicts, and initiate automated re-routing procedures. Selecting an aircraft in the magnified view displays its flight plan, origin/destination, and estimated time of arrival.

Derivative 3.2: Biotechnology - High-Throughput Microscopy for Tissue Analysis

Enabling Description:
An unmagnified electronic map displays a macroscopic view of a tissue sample (e.g., a stained histology slide) at low optical magnification (e.g., 2x objective), with item information representing different cell types, structural anomalies, or labeled biomarkers identified by image processing algorithms. The highlighted portion, controlled by a digital microscope stage, defines a region of interest. The magnified view automatically switches to a high optical magnification (e.g., 40x or 100x objective) for the highlighted area, rendering individual cells, subcellular structures, and quantifying biomarker expression (e.g., immunohistochemistry scoring). Smooth movement of the highlighted region corresponds to precise stepper motor control of the microscope stage, continuously updating the high-resolution image stream. User selection of a cell or anomaly in the magnified view triggers display of its classification (e.g., cancerous, necrotic), morphological parameters (e.g., nuclear-to-cytoplasmic ratio), and links to genomic or proteomic databases for that specific cell type.

Derivative 3.3: Industrial Automation - Smart Factory Floor Layout and Robotic Path Planning

Enabling Description:
An unmagnified electronic map presents a real-time, overhead 2D/3D layout of a factory floor, showing static machinery, dynamic automated guided vehicles (AGVs), robotic arms, and raw material/finished goods inventory locations. Item information includes machine status (e.g., operational, maintenance, error), AGV routes, and material stock levels. A highlighted portion indicates a specific work cell, an AGV's current operating area, or a bottleneck region. The magnified view provides a detailed, often 3D, schematic of the highlighted work cell, displaying individual sensor readings, robot joint positions, tool status, and micro-movements of components. User input via a specialized industrial touchscreen or holographic projection interface enables fluid navigation and immediate visualization of operational data. Selecting a robotic arm in the magnified view brings up its operational logs, predictive maintenance alerts, and allows for real-time adjustment of its programmed path or task sequence (with appropriate safety interlocks).

4. Integration with Emerging Tech

This section details integration of the interactive map with AI, IoT, and Blockchain technologies.

Derivative 4.1: AI-Driven Predictive Maintenance Map for Urban Infrastructure

Enabling Description:
An unmagnified electronic map displays an urban area with overlaid infrastructure networks (e.g., water pipes, electrical grids, communication lines). Item information includes current status, age, material type, and predictive failure scores for each segment, generated by an AI model trained on historical maintenance records, sensor data (IoT), and environmental factors. The highlighted portion automatically focuses on areas with high predicted failure probability or critical events detected by IoT sensors (e.g., sudden pressure drops in water mains, power outages). The magnified view provides a detailed engineering schematic of the affected infrastructure, displaying real-time IoT sensor data (e.g., flow rates, voltage, fiber optic integrity), projected repair timelines from AI algorithms, and resource allocation recommendations. User input (e.g., natural language queries processed by an AI assistant) enables smooth navigation and filtering of predictions. Selecting a pipe segment in the magnified view prompts the AI to simulate the impact of its failure and suggest optimal preventative actions.

Derivative 4.2: IoT-Enhanced Environmental Monitoring Map with Real-time Anomaly Detection

Enabling Description:
An unmagnified electronic map represents a natural reserve or agricultural zone, overlaid with real-time environmental data streams from a dense network of IoT sensors (e.g., soil moisture, air quality, wildlife trackers, temperature, pollution levels). Item information is dynamically generated by fusing sensor data and displayed as heatmaps or animated indicators. Anomaly detection AI continuously monitors these streams. The highlighted portion automatically follows detected environmental anomalies (e.g., wildfire hotspots, abnormal chemical spills, unauthorized human presence) or user-selected areas for detailed inspection. The magnified view provides granular sensor readings, time-series graphs, and specific alarm triggers for the highlighted anomaly, enabling rapid response. User input via a ruggedized tablet with touch and voice control allows smooth movement and deep dives into environmental conditions. Selecting a sensor node in the magnified view displays its operational status, battery life, and communication logs, with data visualized in a GIS-compatible format.

Derivative 4.3: Blockchain-Secured Supply Chain Logistics Map with Immutable Asset Tracking

Enabling Description:
An unmagnified electronic map visualizes a global supply chain network, showing manufacturing facilities, distribution centers, shipping routes, and current locations of various assets (e.g., containers, pallets, individual high-value goods). Item information, sourced from a distributed ledger (blockchain), includes asset ID, ownership history, origin, destination, customs clearance status, and environmental conditions during transit (e.g., temperature for pharmaceuticals). Each asset's journey and status updates are cryptographically secured on the blockchain, ensuring immutability and auditability. The highlighted portion is a user-selected shipment, a specific transportation corridor, or a high-risk customs zone. The magnified view provides a transparent and verifiable record of the highlighted asset's journey, displaying cryptographic proofs of each waypoint, smart contract execution logs, and an auditable trail of custody from the blockchain. User input via secure biometric authentication allows authorized parties (e.g., customs officials, logistics managers) to smoothly trace assets, verify compliance, and drill down into the immutable transaction history.

5. The "Inverse" or Failure Mode

This section explores variations involving inverse functionality, safe failure modes, or limited-functionality operation.

Derivative 5.1: "Privacy-Preserving" Map with Dynamic Anonymization and Role-Based Information Filtering

Enabling Description:
An interactive electronic map operates in a "privacy-preserving" mode for public displays or sensitive applications. The unmagnified map dynamically anonymizes item information based on configurable privacy policies and user roles. For instance, residential addresses are blurred or replaced with generic markers, while real-time individual movement data is aggregated and displayed as heatmaps rather than specific tracks. The highlighted portion, when defined by an authorized user, triggers a gradual de-anonymization process within its boundary, controlled by a secure multi-party computation (MPC) framework to protect underlying sensitive data. The magnified view only reveals specific, granular item information (e.g., individual names, precise GPS coordinates) if the accessing user's credentials (verified via a Zero-Knowledge Proof (ZKP) system) meet the strict privacy policy requirements for that specific data point. In "low-power" mode, the map reverts to a static, low-resolution grayscale display with only essential public service information.

    G[Low-Power Mode] --> A: Grayscale/Static

Derivative 5.2: "Debug & Diagnostic" Map for Complex Software Systems with Runtime Trace Visualization

Enabling Description:
An unmagnified electronic map visually represents the architecture of a complex distributed software system (e.g., microservices, cloud functions), where item information denotes individual services, data queues, or network endpoints. Color coding indicates service health (e.g., green for operational, red for error), and animated flow lines represent real-time message traffic. The highlighted portion, user-defined or triggered by a runtime error, focuses on a specific microservice or data pipeline. The magnified view provides a "deep dive" into that component, showing stack traces, log entries, CPU/memory utilization, and variable states in real-time. This magnified view integrates a sophisticated trace visualization tool (e.g., OpenTracing, Jaeger) that visually represents the call graph and latency of individual requests. User input via a specialized debugging console or command-line interface allows developers to smoothly traverse the system's execution flow, pinpoint performance bottlenecks, and inject test data into the magnified service for live debugging, all without affecting production traffic in "safe failure" debug mode.

Derivative 5.3: Disaster Response Map with Limited Bandwidth "Emergency Mode" and Prioritized Information Display

Enabling Description:
An interactive electronic map is deployed for disaster response scenarios (e.g., earthquake, hurricane). In normal operation, it displays full geographical data, infrastructure status, and real-time incident reports. However, in "emergency mode," triggered by network degradation or power loss, the system automatically shifts to a limited-bandwidth, low-power profile. The unmagnified map displays only critical information (e.g., emergency shelters, safe evacuation routes, known hazard zones) using a highly compressed vector graphics format (e.g., GeoJSON optimized for size) and monochromatic color palette. Item information is strictly prioritized: human casualties, critical infrastructure failures, and emergency resource locations are displayed, while non-essential data is suppressed. The highlighted portion, manually or autonomously positioned over an active incident area, fetches and displays a magnified view with only the most recent (e.g., within 5 minutes) and crucial updates, such as victim count, specific resource needs, or structural integrity reports from first responders. Communication uses a resilient mesh network (e.g., LoRaWAN) to ensure smooth, albeit low-throughput, updates for the magnifier and magnified view, ensuring critical information reaches responders despite degraded conditions.

Combination Prior Art Scenarios

Here are three scenarios where US10444943 could be combined with existing open-source standards to demonstrate obviousness.

1. Combination with OpenStreetMap (OSM) and Leaflet.js:
   The core method of displaying an unmagnified map, a highlighted portion, and a magnified view (Claim 1) is rendered obvious when combined with the capabilities of OpenStreetMap (an open-source collaborative mapping project providing free geographic data) and Leaflet.js (an open-source JavaScript library for mobile-friendly interactive maps). A developer could readily implement a system using Leaflet to render an OSM base map as the "unmagnified electronic map." Custom Leaflet layers or plugins could serve as the "highlighted portion" (e.g., a circular SVG overlay) and an additional map instance or a dynamically resized viewport could provide the "magnified view." Smooth movement and updates would be achieved using Leaflet's pan and zoom controls, which respond to touch or mouse input. Item information (e.g., Points of Interest from OSM data) could be pulled from the OSM API and associated with map coordinates. The bidirectional interactivity is a standard feature of many interactive map libraries where clicking a marker brings up information, and searching for an item focuses the map on it. This combination clearly anticipates the functional aspects of US10444943 using widely available open-source tools.

2. Combination with QGIS and OGC Web Map Service (WMS):
   The system described in Claim 7, comprising a display, input, and processing unit configured to provide the interactive map functionality, becomes obvious when considering Geographic Information System (GIS) software like QGIS (an open-source desktop GIS application) integrated with Open Geospatial Consortium (OGC) Web Map Service (WMS) standards. QGIS can display various geospatial data layers as an "unmagnified electronic map." A WMS server can serve different resolution layers of map data. A user, through QGIS's interface (display and input device), can define a "highlighted portion" (e.g., using a selection tool) and request a higher-resolution WMS layer for that specific area, effectively creating a "magnified view" that updates as the selection moves. The processing unit (computer running QGIS) handles the rendering and WMS requests. Item information, such as attributes associated with GIS features, can be selected from the magnified view, and searching for specific attributes can automatically pan/zoom the QGIS display to the relevant feature, demonstrating the two-way interactivity.

3. Combination with HTML5 Canvas API and WebSockets for Real-time Updates:
   Independent Claim 14, describing a computer program product for the interactive map, is anticipated by combining standard web technologies like the HTML5 Canvas API and WebSockets. A web application could use the Canvas API to draw a vector-based "unmagnified electronic map" and its associated item information (e.g., rendered text labels, SVG icons). A second Canvas element or a manipulated viewport could act as the "magnified view." User input (mouse, touch) could directly manipulate coordinates on the primary Canvas to define and smoothly move a "highlighted portion" (e.g., a dynamically rendered circle or rectangle). WebSockets could be employed to push real-time updates of map data or item information from a backend server, ensuring the smooth updates of both views. JavaScript event listeners handle user selection of items for displaying additional details, and client-side JavaScript functions would handle repositioning the map based on search queries for item information. This setup inherently provides the core functionality of US10444943 using widely understood and implemented open web standards.
