• Plaintiff(s): IngenioSpec LLC
• Defendant(s): [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)
• Jurisdiction: Texas Western District Court
• Case Number: 1:25-cv-01101
• Filing Date: July 15, 2025
• Outcome/Current Status: The case was dismissed, and the Clerk's Office was instructed to close the case as of June 15, 2026.

Proceedings overview

There is one pending AIA trial proceeding for US patent 12313913, IPR2026-00419. This means the patent's claims are currently undergoing review for patentability, and no claims have been invalidated or sustained by the PTAB yet. Therefore, the defensive posture for a defendant is that the patent's validity is still in question.

• Judge panel: Not yet assigned or publicly available for a pending petition.
• Petition grounds: Not yet publicly available from the provided information for a pending petition.
• Institution decision: Not yet issued. The PTAB has a statutory deadline of six months from the filing of the preliminary response to decide whether to institute the IPR.
• Final Written Decision (if issued): Not yet issued.
• Settlement / termination: No settlement or termination has been reported.
• Appeal: Not applicable, as no Final Written Decision has been issued.
• Defensive value: This active IPR proceeding indicates that at least some claims of US12313913 are being challenged by Apple Inc. A defendant currently facing assertion of this patent may benefit from monitoring this proceeding, as a successful challenge could invalidate asserted claims.

Strategic summary

As of July 14, 2026, there is one active Inter Partes Review (IPR) proceeding, IPR2026-00419, filed by Apple Inc. against US patent 12313913. This proceeding is currently in the pre-institution phase, meaning the PTAB has not yet decided whether to formally initiate the review. Consequently, no claims of US12313913 have been canceled or sustained by the PTAB, and all claims remain "untested" in terms of a final PTAB decision.

The estoppel landscape under § 315(e)(2) will only become relevant if the IPR is instituted and proceeds to a Final Written Decision. If claims are challenged and found unpatentable, Apple Inc. (and its privies) would be estopped from raising the same or reasonably could have raised grounds in future proceedings. As the proceeding is still pending institution, there are no immediate estoppel implications.

The filing of this IPR by Apple Inc., a defendant in the related District Court litigation (1:25-cv-01101), indicates a clear defensive strategy to challenge the patent's validity at the PTAB.

Recommended next steps

The IPR2026-00419 proceeding is currently in the preliminary stages. A key upcoming milestone will be the PTAB's decision on institution, which is typically due within six months of the patent owner's preliminary response or the filing date of the petition if no preliminary response is filed. Monitoring the progress of IPR2026-00419 through the USPTO PTAB E2E system is crucial to track the institution decision, potential claim challenges, and any subsequent developments.

To identify the most relevant prior art for US patent 12313913, I will access the patent information directly from the USPTO. I will specifically look for the "Cited By" or "References Cited" section of the patent to get a list of prior art documents.

As of today's date, April 26, 2026, the official USPTO website is the authoritative source for patent information.

Unfortunately, I cannot directly browse the USPTO database or interact with the Patent Public Search tool directly to extract the "References Cited" section. The provided full patent text does not include the list of cited prior art. Therefore, I cannot provide a detailed analysis of each patent citation, including full citation, publication/filing date, brief description, and which claims it potentially anticipates under 35 U.S.C. § 102.

I recommend accessing the official US12313913B1 patent document through the USPTO Patent Public Search or Google Patents to review its "References Cited" section for a comprehensive prior art analysis.

I cannot perform a comprehensive obviousness analysis under 35 U.S.C. § 103 at this time. The "Prior Art" section, which was previously generated and intended as the basis for this analysis, explicitly states that the necessary prior art references (specifically, the "References Cited" section of US12313913B1) were not available.

Without a list of cited prior art documents, it is impossible to identify combinations of references or articulate motivations for a Person Having Ordinary Skill in the Art (PHOSITA) to combine them, which are essential components of an obviousness analysis.

To proceed with this task, access to the full text of US12313913B1, including its "References Cited" section, would be required.

I am unable to directly access and browse the live USPTO database to pull up the Patent Term Adjustment (PTA), Patent Term Extension (PTE), and detailed application lineage information for US patent 12313913 at this moment. However, based on the provided patent text and Google Patents summary, I can compile the available information and note any inferences.

Patent Term Adjustment (PTA) and Patent Term Extension (PTE)

The Google Patents overview for US12313913B1 lists an "Anticipated expiration" date of 2026-10-11. A U.S. utility patent generally expires 20 years from its earliest effective filing date. The earliest priority date for US12313913 is 2005-10-11. Twenty years from this date would be October 11, 2025. The anticipated expiration date of October 11, 2026, suggests an additional term of approximately one year. This extension would typically be due to Patent Term Adjustment (PTA), which compensates for certain administrative delays by the USPTO during prosecution of a patent application. Without direct USPTO documentation, it is not possible to definitively confirm the exact PTA calculation or if any PTE applies.

Continuation and Divisional Applications

US12313913B1 (Application number US18/597,874, filed 2024-03-06) is part of a patent family that claims priority from several earlier applications. These are listed as "external-priority" documents in the patent information and represent the lineage of this patent, indicating a series of continuation or divisional applications. A continuation application pursues additional claims on the same invention as a parent application, while a divisional application is filed when an original application contains more than one invention, often in response to a USPTO restriction requirement. Both types retain the priority date of the earliest parent application.

The patent US12313913B1 claims priority from the following applications:

• US11/580,222 (Priority claimed from 2006-10-11)
• US11/891,411 (Priority claimed from 2007-08-09)
• US12/462,286 (Priority claimed from 2009-07-31)
• US12/806,312 (Priority claimed from 2010-08-10)
• US13/085,402 (Priority claimed from 2011-04-12)

This chain of priority claims establishes US12313913B1 as a continuation or divisional within a larger patent family, all deriving their effective filing date from the earliest claimed priority date of 2005-10-11.

Related Family Members

The related family members are those applications from which US12313913B1 claims priority, as detailed above. These are earlier applications in the same patent family, sharing a common priority date of October 11, 2005. The full patent text also lists additional priority claims for the application number US18/597,874:

• Priority to US18/597,874 (2024-03-06)
• Priority to US18/948,670 (2024-11-15)
• Priority to US18/991,006 (2024-12-20)

These more recent priority claims likely indicate further continuing applications filed after the application that matured into US12313913B1, or that these are related applications that were themselves filed on these dates and are part of the same portfolio claiming common subject matter.

Projected Expiration Date

Based on the Google Patents summary provided in the initial prompt, the "Anticipated expiration" date for US12313913B1 is 2026-10-11.

As a Senior Patent Strategist and Research Engineer specializing in Defensive Publishing, my objective is to outline a "Defensive Disclosure" for US patent 12313913, "System for powering head-worn personal electronic apparatus." This document aims to establish prior art for future incremental improvements by competitors, rendering them obvious or non-novel under 35 U.S.C. § 103 or § 102.

Important Note on Claims: The previously generated "Prior Art" section explicitly stated that the full text of the claims for US12313913B1 was not available in the provided information. While a live search was conducted, direct access to the specific numbered claims for programmatic analysis is still unavailable. To proceed with the generation of derivative works as requested, I will interpret the detailed descriptions of the invention provided in the patent's "Definitions" section as foundational concepts, analogous to core claims, to develop comprehensive defensive disclosures. This approach ensures the spirit of the task is met by deriving variations from the disclosed inventive subject matter.

I will focus on three conceptual claims derived from the patent's descriptive text:

Conceptual Claim 1 (CC1): Modular Eyewear with Electrical Components in Temples
This concept encompasses the integration of electrical components into temple arrangements (temple tips, fit-overs, covers) and multi-part temples with removable forward/rearward portions, facilitating interchangeable functionalities.

Conceptual Claim 2 (CC2): Head-Worn Apparatus with Integrated Sensory and Communication Systems
This covers the incorporation of temple adapters, bone conducting elements, various sensors ("being worn," environmental, condition), noise cancellation, microphones, and speakers for enhanced communication and monitoring.

Conceptual Claim 3 (CC3): Powering and Charging Systems for Head-Worn Apparatus
This includes rechargeable batteries, electrical connectors, docking stations, and tethered power sources for sustained operation of the integrated electrical components.

Defensive Disclosure Document for US 12313913

Conceptual Claim 1 (CC1): Modular Eyewear with Electrical Components in Temples

This conceptual claim covers eyewear, such as eyeglasses, comprising temples or temple arrangements (e.g., temple tips, fit-overs, covers) that include one or more electrical components, which can be attached or at least partially embedded therein (FIG. 1, FIG. 2, FIG. 3A-3C). Furthermore, it covers multi-part temples where a forward portion removably couples with a rearward portion, allowing for the swapping of rearward portions to alter electrical functionalities (e.g., battery/power, wireless communication, radio, headset, GPS, pedometer, sun sensor, hearing enhancement, image/video capturing) (FIG. 3F-3H).

Derivative Variations for CC1:

1. Material & Component Substitution: Carbon Nanotube Composite Temples with Solid-State Thin-Film Batteries and Flexible PCB

   • Enabling Description: The temples, or at least the removable rearward portions, are fabricated from a carbon nanotube (CNT) reinforced polymer composite, offering superior strength-to-weight ratio and electrical conductivity. Electrical components are integrated using flexible printed circuit boards (FPCBs) that conform to the temple's curvature, significantly increasing volumetric efficiency. Power is supplied by a solid-state thin-film lithium-ion battery embedded within the composite matrix, connected to the FPCB via microscopic conductive traces. Mechanical coupling between forward and rearward parts utilizes a spring-loaded, multi-pin pogo array for reliable electrical and mechanical connection, enclosed within a hydrophobic sealing layer to prevent moisture ingress.

2. Operational Parameter Expansion: Extreme Environment Monitoring Eyewear for Industrial Safety

   • Enabling Description: The modular eyewear is designed for use in hazardous industrial environments, operating across extreme temperatures (-40°C to 85°C) and pressures (up to 10 atm). Temples incorporate hermetically sealed modules containing radiation-hardened microcontrollers and sensors for detecting specific airborne chemical toxins (e.g., CO, H2S, NH3 via MEMS gas sensors) and particulate matter. Communication occurs via ultra-low power wide area network (LPWAN) modules (e.g., LoRaWAN) optimized for signal penetration through industrial infrastructure, with data transmission at sub-kHz frequencies to maximize range and minimize interference. Power is sourced from high-capacity, low-temperature tolerant solid-state batteries.

3. Cross-Domain Application: Precision Agriculture (AgTech) Sensing Eyewear

   • Enabling Description: Eyewear temples are equipped with specialized sensors for agricultural applications. The removable rearward portion can contain a multi-spectral imaging sensor (visible, near-infrared) and a GPS module for geo-tagging. Farmers or agronomists wear these glasses to visually inspect crops, with the integrated sensors capturing subtle changes in plant health (e.g., chlorophyll content, water stress) that are invisible to the naked eye. The forward portion includes a display (e.g., micro-OLED) for real-time overlay of plant health indices. Data is uploaded via a short-range wireless module (e.g., Bluetooth Low Energy) to a ruggedized handheld device for further analysis and integration with farm management systems.

4. Integration with Emerging Tech: AI-Optimized Adaptive Power Management and AR Overlay

   • Enabling Description: The eyewear incorporates an AI-driven power management unit within the forward temple, continuously analyzing user activity, ambient light conditions, and sensor data (e.g., from an integrated eye-tracking sensor) to dynamically optimize power consumption across all integrated electrical components. For instance, if the user is in a dimly lit environment and reading, the system prioritizes display brightness and de-emphasizes non-critical sensors. Integration with augmented reality (AR) micro-displays (e.g., LCoS) in the lenses allows for context-aware information overlay, such as real-time notifications, navigation cues, or health metrics, which are generated by an on-board AI inference engine optimized for low-power edge computing.

5. The "Inverse" or Failure Mode: Low-Power Guardian Mode Eyewear

   • Enabling Description: In a low-power or critical battery state, the eyewear transitions to a "Guardian Mode." Non-essential electrical components (e.g., video recording, GPS, advanced communication) are deactivated. The system retains only core safety functionalities: a minimal "being worn" sensor (e.g., a simple contact switch) to detect if the glasses are on the user, and a low-frequency, low-power beacon (e.g., a sub-1GHz radio operating on ISM band) capable of emitting an emergency signal for location tracking. The display, if present, shows only a critical battery warning or an "SOS" indicator. This mode ensures prolonged operation (e.g., for several days) for essential safety alerts or basic identification.

Conceptual Claim 2 (CC2): Head-Worn Apparatus with Integrated Sensory and Communication Systems

This conceptual claim encompasses head-worn apparatus like eyewear having temple adapters (FIG. 6, FIG. 7A-7B, FIG. 8A-8B, FIG. 9A-9D) and/or bone conducting elements (FIG. 10A-10C) for audio output. It also covers the integration of various sensors, including "being worn" sensors (FIG. 5, FIG. 14), environmental sensors (e.g., radiation, temperature, pressure, humidity, toxins), and condition sensors (e.g., distance, location, speed, calories, temperature, vital signs, emotional conditions) (FIG. 5). Noise cancellation functionality (FIG. 17) and directional microphones for improved audio pickup are also covered.

Derivative Variations for CC2:

1. Material & Component Substitution: Graphene-Membrane Micro-Speakers and Biometric Polymer Sensors

   • Enabling Description: Instead of traditional electromagnetic speakers, the temple adapters utilize micro-speakers with graphene diaphragms for superior audio fidelity, lower power consumption, and thinner profiles. These are integrated directly into the temple adapter for in-ear delivery. Biometric sensors, crucial for condition monitoring (e.g., heart rate, blood oxygen), are fabricated from flexible, conductive polymer films conformally integrated into the inner surface of the temple that contacts the wearer's skin. These polymer sensors provide continuous, non-invasive vital sign monitoring via impedance plethysmography or photoplethysmography (PPG).

2. Operational Parameter Expansion: Hyperspectral Environmental Monitoring Eyewear for Disaster Response

   • Enabling Description: Eyewear is equipped with temple-mounted, miniaturized hyperspectral imagers operating across UV-Vis-NIR (200-1100 nm) spectrum, capable of real-time detection and mapping of hazardous chemical plumes (e.g., toxic industrial chemicals, chemical warfare agents) in disaster zones. The device operates with enhanced processing power to analyze spectral signatures in real-time, offering detection limits in parts-per-billion (ppb) ranges. Thermal sensors cover an extended range (-50°C to 200°C) for detecting hotspots. Communication modules utilize satellite backhaul (e.g., Iridium SBD) for operation in areas with no terrestrial infrastructure, transmitting critical threat data at burst rates for minimal power draw.

3. Cross-Domain Application: Canine Companion Health & Training Eyewear

   • Enabling Description: Designed for use by dog trainers or handlers, this eyewear integrates sensors to monitor the physiological and emotional state of a working dog (e.g., police K9, service dog). The temple-worn electrical components include a bone conduction module that transmits specific audio commands (inaudible to humans) to the dog via a bone-conducting collar. Sensors in the eyewear (e.g., micro-accelerometers, galvanic skin response (GSR) sensors on the handler's temple contact points) are paired with the dog's wearable sensors (e.g., heart rate, respiration via chest strap) via a secure short-range wireless link. This allows the handler's stress levels or movement patterns to be correlated with the dog's responses, offering insights into effective training techniques or early detection of handler fatigue impacting dog performance.

4. Integration with Emerging Tech: IoT Sensor Mesh for Personalized Wellness Feedback

   • Enabling Description: The eyewear features an array of IoT sensors (e.g., miniaturized air quality sensors, ambient light sensors, proximity sensors) integrated into the temple structure, forming a personal environmental monitoring mesh. These sensors continuously feed data to an on-board microcontroller, which then pushes aggregated and anonymized data to a distributed ledger technology (DLT) network (e.g., a permissioned blockchain like Hyperledger Fabric) for secure, immutable record-keeping of personal wellness data. An AI module within the eyewear processes this data to provide real-time, personalized wellness feedback via subtle haptic feedback or audio prompts (e.g., "Air quality is poor, consider taking a break indoors," "Insufficient natural light detected, step outside"). User consent for data sharing is managed via smart contracts on the DLT.

5. The "Inverse" or Failure Mode: Stealth Mode Eyewear for Covert Operations

   • Enabling Description: This eyewear includes a "Stealth Mode" designed for covert operations where detection avoidance is paramount. In this mode, all active electromagnetic emissions (e.g., Wi-Fi, Bluetooth, GPS, cellular) are completely suppressed. The display (if any) is either deactivated or switched to an ultra-low luminance, monochrome state. Microphones are switched to a passive acoustic listening mode without internal recording or transmission. Any "being worn" sensors are disabled to prevent inadvertent activation or signaling. The only active electrical components would be a highly localized, short-range (e.g., sub-cm) near-field communication (NFC) interface for data extraction, activated only when physically pressed against a dedicated reader, ensuring no detectable emissions during normal use.

Conceptual Claim 3 (CC3): Powering and Charging Systems for Head-Worn Apparatus

This conceptual claim pertains to various methods for powering and charging the electrical components within head-worn apparatus. This includes the use of embedded rechargeable batteries, electrical connectors for charging (e.g., via a cable or docking station), and tethered power sources (e.g., a base unit connected via a cord) (FIG. 3F, FIG. 13C). The patent also discusses electrical connectors or conductive elements on the frame to facilitate contact charging with a docking station.

Derivative Variations for CC3:

1. Material & Component Substitution: Multi-Layer Flexible Supercapacitors and Inductive Charging Films

   • Enabling Description: Replace conventional rechargeable batteries with flexible, multi-layer graphene-based supercapacitors integrated directly into the temple structure. These supercapacitors offer rapid charging/discharging cycles and improved lifespan compared to batteries. Charging is accomplished wirelessly via ultra-thin, flexible inductive charging films embedded within the temples. The charging films receive power from a low-profile inductive mat, allowing the eyewear to be charged by simply placing it on a flat surface or a compatible eyewear case, eliminating exposed connectors and enhancing water resistance.

2. Operational Parameter Expansion: High-Voltage, Ultra-Fast Charging for Emergency Services

   • Enabling Description: Eyewear designed for emergency services features high-voltage (e.g., 24V), ultra-fast charging capabilities to minimize downtime. The integrated battery system comprises advanced lithium-sulfur (Li-S) cells optimized for high energy density and rapid charge acceptance. Charging connectors are ruggedized, magnetic-latching, multi-contact interfaces (e.g., similar to military-grade quick-disconnects) designed for harsh environments. The charging protocol involves a multi-stage constant-current/constant-voltage (CC/CV) profile delivered by a specialized power supply, allowing a full charge in under 5 minutes. Integrated thermal management (e.g., passive heat sinks, phase-change materials) prevents overheating during rapid charging.

3. Cross-Domain Application: Space Exploration Wearable Power System

   • Enabling Description: Eyewear for astronauts or space station personnel incorporates power systems adapted for the vacuum and radiation of space. Temples house compact radioisotope thermoelectric generators (RTGs) for long-duration, maintenance-free power generation, supplemented by miniaturized flexible solar cells for opportunistic charging in illuminated environments. Charging ports, if present, are hermetically sealed, utilizing non-contact optical power transfer (e.g., focused laser diode charging) or inductive charging through a hermetic barrier, ensuring no atmosphere contamination or outgassing. The RTG provides a continuous trickle charge, while solar cells provide burst charging when exposed to sunlight.

4. Integration with Emerging Tech: Predictive Maintenance Power Management with Digital Twin

   • Enabling Description: The eyewear's power management system incorporates a digital twin hosted in a secure cloud environment, mirroring the real-time state and degradation of the on-board rechargeable battery (e.g., Li-ion polymer). IoT sensors within the battery pack (e.g., temperature, internal resistance, charge cycles) continuously feed data to the digital twin, which employs AI/machine learning algorithms to predict battery lifespan, optimal charging schedules, and potential failure points. This predictive maintenance data is relayed back to the eyewear, providing proactive user alerts for charging ("Recharge within 2 hours for optimal lifespan") or recommendations for battery replacement. A blockchain-based supply chain record for each battery unit ensures authenticity and traceable maintenance history.

5. The "Inverse" or Failure Mode: Kinetic Energy Harvesting for Emergency Backup Power

   • Enabling Description: To ensure continuous basic functionality even when primary power sources fail or are depleted, the eyewear incorporates a miniaturized kinetic energy harvesting system. Micro-electromechanical systems (MEMS) based piezoelectric or electromagnetic generators are strategically placed within the temple hinges or flexible temple sections. These generators convert the kinetic energy from subtle head movements (e.g., walking, talking, turning the head) into electrical energy. This harvested energy is stored in a small, low-leakage capacitor, providing enough power for critical functions like an emergency low-power LED beacon or a single button press for an SOS signal, operating as a last-resort power source.

Combination Prior Art Scenarios with Open-Source Standards

Here are three scenarios where the concepts of US12313913 could be combined with existing open-source standards, demonstrating how these combinations could render future improvements obvious:

1. Modular Eyewear with Electrical Components + Open-Source Hardware Development Boards (e.g., ESP32-WROOM-32 Module)

   • Description: The concept of removable temple parts or temple adapters containing various electrical functionalities (CC1) can be readily combined with widely available open-source hardware modules. For example, a rearward temple portion containing a Wi-Fi/Bluetooth module, a microcontroller, and memory (as described in the patent) could be implemented using an off-the-shelf ESP32-WROOM-32 module (an open-source standard for IoT connectivity), along with a small LiPo battery. The mechanical and electrical interface between the forward and rearward temple parts could be defined by an open standard such as the USB-C physical interface and power delivery protocols (already an open-source standard with defined mechanical and electrical specifications). A maker or hobbyist could easily design and 3D-print compatible temple parts to house such a module, effectively creating custom "smart" eyewear. This combination makes the mere integration of generic processing and communication capabilities into a modular eyewear component obvious, as the underlying components and interface standards are openly documented and accessible.
   • Relevance: Anticipates claims on modular temples providing generic processing/communication.

2. Integrated Sensory Systems + IEEE 802.15.4 (Zigbee/Thread) for Personal Area Networks

   • Description: The integration of various environmental or condition sensors (e.g., temperature, humidity, UV, motion) within eyewear (CC2) can be combined with open wireless communication standards like IEEE 802.15.4 (which underpins Zigbee and Thread). Imagine an eyewear system where temple-embedded environmental sensors form a low-power wireless personal area network (WPAN) using Thread. This allows sensor data to be seamlessly collected by other nearby Thread-enabled devices (e.g., a smartwatch, smartphone, or home automation hub) without requiring a direct connection to a specific mobile phone. The data exchange protocols for Thread are open and publicly available. A system where eyewear functions as an intelligent sensor node within a broader Thread network, reporting environmental or biometric data, would be an obvious application of existing technologies.
   • Relevance: Anticipates claims on eyewear with integrated sensors that communicate wirelessly.

3. Powering/Charging Systems + Qi Wireless Power Transfer Standard

   • Description: The concept of wirelessly charging eyewear through docking stations or inductive means (CC3) can be directly combined with the globally recognized Qi Wireless Power Transfer standard. An eyewear frame or temple could incorporate a miniature Qi receiver coil and associated circuitry. This allows the eyewear to be charged by simply placing it on any Qi-compatible charging pad (e.g., a phone charging pad, integrated into furniture, or a specially designed eyewear case acting as a docking station). The Qi standard (developed by the Wireless Power Consortium) is an open interface standard. Implementing Qi-compliant wireless charging in eyewear would be a straightforward engineering application of an existing, well-defined open standard.
   • Relevance: Anticipates claims on wireless power transfer mechanisms for eyewear.
