Abstract:
The patent describes a vehicular battery charger, charging system, and associated methods. The system features a vehicle charger adapted for communication with a remote first controller, such as from a power utility or a user's device. This charger includes an electrical power cord, a local second controller, and a transceiver, allowing the second controller to adjust the charger's state based on signals from the first controller. The invention also encompasses vehicle chargers with user interfaces (displays and controls) for programming charging sessions based on a desired end time, displaying charging information like time remaining, power consumed, and cost, and can account for electricity pricing. Variations include chargers with internal batteries, multiple vehicle connectors, and systems utilizing inductive charging with positional feedback for optimal alignment. Additionally, a method is disclosed for centrally managing battery charging for multiple vehicles connected to a power grid, optimizing power supply based on user-specified completion times.

Plain-Language Overview of Independent Claims (based on "Definitions" section):

The patent broadly covers several independent inventive concepts, summarized below:

1. Remote-Controlled Vehicle Charger: A vehicle charger for an electric vehicle battery that can communicate with a remote controller. It features an electrical power cord, a local controller, and communication hardware (transmitter/receiver). This local controller can change the charger's operational state based on signals received from the remote controller.
2. Time-of-Day End-Time Controlled Charger: A vehicle charger with a controller, a display for time, and user controls to set a charging session end time. The controller manages the power supply to the battery (e.g., increasing/decreasing charge rate, starting/stopping charging) to ensure the battery is charged by the user-specified end time.
3. In-Vehicle Display & Control Charger: A vehicle charger that includes a display and user controls located within the vehicle's interior. A controller connected to this display and the battery adjusts the power supply during charging based on a user-entered time of day.
4. Threshold Charge Independent of Time Charger: A vehicle charger with a controller and memory to store a user-entered time of day for charging adjustments. Crucially, if the battery charge falls below a preset threshold, the controller supplies power to the battery regardless of the user-entered time, until that threshold is met.
5. Multi-Screen Display Charger: A vehicle charger with a controller, a display, and memory to save time-of-day settings. The charger's controller can display at least two different screens: one for charging session information and another for charger settings.
6. Remote Communication Status Display Charger: A vehicle charger that communicates with a remote controller. It includes a display coupled to a local controller, which manages power supply based on a time of day, and a transceiver for remote communication. The local controller displays an indicator showing the status of communication with the remote controller.
7. Time Remaining Display Charger: A vehicle charger with a controller and display that can adjust battery charging based on a time of day. The controller is capable of displaying the estimated time remaining until the battery is fully charged.
8. Power Consumed Display Charger: A vehicle charger with a controller and display that can adjust battery charging based on a time of day. The controller is capable of displaying the amount of power consumed by the battery during the charging session.
9. Cost of Power Display Charger: A vehicle charger with a controller and display that can adjust battery charging based on a time of day. The controller is capable of displaying the cost of power supplied to the charger.
10. Cord-Integrated Display & Control Charger: A vehicle charger with an electrical power cord that includes a housing on the cord. This housing contains a controller, a display, and user controls to enter a time of day. The controller then adjusts power supply based on this user-entered time.
11. Remote-Controlled Charger with User Input: A vehicle charger communicating with a remote controller, featuring a display and user controls. A local controller, coupled to the display, modifies the charging process (rate, start/stop) and is responsive to both remote signals and user-entered time-of-day information to change its charging state.
12. Power Interruption Notification Charger: A vehicle charger with a controller that manages power supply based on a time of day. This controller is configured to transmit a signal if it detects an interruption in the power supply to the charger.
13. Charger with Internal Battery Control: A vehicle charger that includes its own internal battery, which is coupled to a controller. An electrical power cord connects the vehicle's battery to either the vehicle or the charger's internal battery. The controller adjusts the charging of the charger's internal battery based on a time of day.
14. Inductive Charging with Positional Feedback: A vehicle charger for inductive charging, comprising a first core on the vehicle and a second stationary core. Sensors detect the relative position of the cores, and a vehicle-mounted display, coupled to a controller, provides indicators to the user on how to move the vehicle to improve the positional relationship between the cores.
15. Vehicle with Dual Charging Connectors: A vehicle battery charging system that features a controller and two electrical connectors on different sides of the vehicle, both capable of being connected to an external power cord for charging.
16. Method for Coordinated Multi-Vehicle Charging: A method for managing battery charging for multiple vehicles connected to a power grid. It involves establishing communication with each vehicle's battery charger, obtaining a desired charging completion time from each, and then adjusting the power supply to at least some of the chargers based on these completion times.

Proceedings overview

There are no AIA trial proceedings on file for US Patent 10090567 as of today's date, June 9, 2026. The USPTO Open Data Portal (ODP) API returns no AIA trial proceedings for this patent, and web searches did not surface any additional proceedings.

Strategic summary

Currently, all claims of US Patent 10090567 remain untested by AIA trial proceedings. This means that no claims have been canceled or sustained through IPR, PGR, or CBM trials. For a defendant facing assertion of this patent, the full scope of prior art grounds under 35 U.S.C. §§ 102 and 103 (and potentially § 112 for PGR/CBM) remains available for potential challenges at the PTAB, subject to statutory time bars (e.g., one year from service of a complaint alleging infringement for IPRs, or nine months from patent grant for PGRs). The absence of PTAB activity suggests that the patent has not yet been subject to the rigorous challenge often seen with frequently asserted patents.

Recommended next steps

Since no PTAB activity exists for US Patent 10090567, a defendant facing assertion should consider filing an AIA trial petition (IPR or PGR, if applicable) if a strong prior art challenge can be mounted. The lack of prior PTAB challenges means there is no estoppel landscape from previous proceedings, leaving all eligible prior art arguments open. Further investigation into potential prior art not considered during examination would be a crucial first step.

Inventors

The sole named inventor for US Patent 10090567 is Christopher B. Austin. At the time of the patent's filing (2009-08-18), the original assignee was listed as "Individual," which refers to Christopher B. Austin himself. This indicates that he was likely not employed by a company in a capacity that would automatically assign the patent rights to that company, or he chose to file it under his individual name. Christopher B. Austin is also a registered patent attorney.

Original assignee

The entity named as the original assignee on the issued patent is "Individual," referring to the inventor, Christopher B. Austin.

NPE / troll-pattern signals

1. Shell-entity transfer — present
   The patent was transferred from individual inventor Christopher B. Austin to CHARGELOGIC LLC in 2026. CHARGELOGIC LLC explicitly states its mission is to "offer licensing solutions to a portfolio of patents that cover technology relating to Electric Vehicle charging". Their website indicates their business model is patent licensing, not product sales, and lists a suite/PO Box address in Midland, Texas. This strongly suggests it is a licensing-only entity.

2. Known asserter in the chain — unclear
   While CHARGELOGIC LLC is a patent licensing entity, it is not currently listed on common public NPE directories (e.g., RPX, Unified Patents). However, the business model aligns with that of an NPE.

3. Repeat correspondent across the chain — unclear
   The only recorded assignment for this specific patent lists MATTHEW R. HOLLAND of HOLLAND LAW FIRM as the correspondent. Without other assignments for this patent or a broader search of other patents where this correspondent appears, it is unclear if this is a recurring pattern for this firm/attorney in NPE-related activities.

4. Cascading transfers — not present
   There is only one recorded assignment for this patent to date, so no cascading transfers are observed.

5. Pre-litigation transfer — present
   The assignment to CHARGELOGIC LLC was executed on 2026-02-22 and recorded on 2026-02-23 (Reel 059940/0989). The litigation in the Texas Western District Court (7:26-cv-00100) was filed in 2026. This timing suggests the transfer occurred very close to or just before the litigation commenced, which is a strong indicator of a pre-litigation transfer to establish venue or standing for assertion.

6. Bankruptcy fire-sale — not present
   There is no indication that the original inventor, Christopher B. Austin, filed for bankruptcy leading to this assignment.

7. Privateering — unclear
   There is no public information or SEC filings available to suggest that an operating company transferred this patent to CHARGELOGIC LLC for assertion on its behalf.

8. Defensive aggregator (anti-NPE) — not present
   The current assignee, CHARGELOGIC LLC, is not a known defensive aggregator.

Verdict

NPE — high confidence

The patent was transferred from an individual inventor to CHARGELOGIC LLC (Reel 059940/0989), an entity whose stated business model is solely "licensing solutions to a portfolio of patents" related to EV charging. This, combined with the timing of the assignment immediately preceding a known lawsuit in the Texas Western District Court (7:26-cv-00100), strongly indicates the patent is now held by a Non-Practicing Entity for the purpose of assertion.

USPTO Assignment Center search for US10090567: https://assignmentcenter.uspto.gov/

To identify the most relevant prior art for US patent 10090567, I will search the USPTO Patent Public Search database (since the PatFT/AppFT databases have been retired) for the patent and then extract its cited references. I will then analyze each cited reference for its publication/filing date, a brief description, and which claim(s) of US10090567 it potentially anticipates under 35 U.S.C. § 102.

Unfortunately, I cannot directly access the USPTO Patent Public Search tool to perform the search and retrieve the detailed citation information. Therefore, I cannot provide the specific prior art citations and their analysis as requested.

To complete this task, you would typically need to:

1. Access the USPTO Patent Public Search tool. (e.g., https://www.uspto.gov/patents/search or through Patent Center).
2. Search for US Patent 10090567. Ensure to enter the patent number correctly, omitting commas and spaces and adding leading zeros if necessary to make it 7 or 8 digits, depending on the patent number formatting rules for utility patents.
3. Locate the "References Cited" section of the patent document.
4. For each cited patent or publication:
   • Record the full citation (Patent Number, Inventor/Applicant, Issue/Publication Date).
   • Determine the publication or filing date.
   • Read the abstract and, if necessary, relevant portions of the specification and claims of the cited reference to formulate a brief description of its relevant teachings.
   • Compare the teachings of the cited reference to the claims of US10090567 to identify which claim(s) it potentially anticipates under 35 U.S.C. § 102. Anticipation means that every element of a claim is found, either explicitly or inherently, in a single prior art reference.

To perform an obviousness analysis under 35 U.S.C. § 103, it is necessary to identify specific prior art references and their teachings. This involves:

1. Identifying a primary prior art reference that discloses most, if not all, elements of a claim.
2. Identifying secondary prior art references that disclose the remaining elements.
3. Articulating a clear reason (motivation) why a person having ordinary skill in the art (POSITA) would have combined these references to arrive at the claimed invention, with a reasonable expectation of success.

The "Prior Art" section in the previously generated analysis explicitly states that I cannot access the USPTO Patent Public Search tool to retrieve the detailed citation information for US10090567. Without this critical information, I cannot identify specific prior art references, their contents, or how they might be combined.

Therefore, I cannot provide an analysis of obviousness for US Patent 10090567 under 35 U.S.C. § 103 at this time.
