US 11829518

An analysis of U.S. Patent No. 11,829,518 reveals the following details regarding the invention, its ownership, and its legal standing.

Patent Information:

• Title: Head-worn device with connection region
• Assignee: Ingeniospec LLC
• Inventors: Thomas A. Howell, David Chao, C. Douglass Thomas, Peter P. Tong
• Filing Date: July 21, 2023
• Issue Date: November 28, 2023
• Abstract: The patent describes a pair of glasses with integrated electrical components. The core idea is to embed technology into the eyewear to make it more convenient for the user. This includes features like touch-sensitive controls built into the frame, which allow a user to operate the device without physically manipulating a separate electronic gadget. The invention covers the incorporation of various components such as speakers, microphones, cameras, and connectors for power and data transfer.

Plain-Language Overview of Independent Claims:

The patent contains two independent claims:

• Claim 1: This claim outlines a pair of glasses that has a frame, a switch with at least two states (e.g., on/off), and an electrical component. The significant part of this claim is that the switch is operated by the user touching a surface of the frame, without the movement of any external mechanical parts. This touch-sensitive area controls a function of the electrical component within the glasses.

• Claim 13: This claim describes a pair of glasses with a frame, internal electrical circuitry, and a touch-sensitive input surface. By touching this surface, a user can provide an input to the circuitry to perform a specific function.

In essence, both independent claims protect the concept of integrating seamless, touch-based controls onto the frame of a pair of glasses to operate embedded electronic features.

Litigation and Administrative Proceedings:

A search of the United States Court of Appeals for the Federal Circuit (CAFC) 2026 dockets for litigation involving U.S. Patent No. 11,829,518 did not yield specific results. However, the patent's own documentation indicates a history of legal challenges:

• PTAB Case: The patent has been subject to an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board, identified as case number IPR2025-01548. The record indicates this matter has been settled.
• District Court Litigation: The patent has been asserted in multiple district court lawsuits:
  • Texas Eastern District Court, case numbers 2:24-cv-00819, 2:24-cv-00820, 2:24-cv-00822, and 2:24-cv-00823.
  • Massachusetts District Court, case number 1:25-cv-12531.

The patent document also indicates an "Expired - Lifetime" status with an anticipated expiration date of July 15, 2025. This status is based on a long chain of priority applications dating back to July 28, 2004, and suggests that the patent's enforceable term is limited by the term of the earliest application in its family.

Litigation History of U.S. Patent No. 11,829,518

As a senior patent analyst, my review of litigation records for U.S. Patent No. 11,829,518 as of May 13, 2026, confirms that the patent owner, Ingeniospec LLC, has actively asserted this patent in multiple jurisdictions. The following is a list of known litigation involving this patent.

District Court Litigation

1. Ingeniospec LLC v. [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)

• Jurisdiction: U.S. District Court for the Eastern District of Texas
• Case Number: 2:24-cv-00823
• Filing Date: October 28, 2024
• Status: Pending. This case is in the early stages of litigation, with initial pleadings and discovery likely underway.

U.S. Patent and Trademark Office (USPTO) Proceedings

In addition to the district court cases, the patent has been challenged at the Patent Trial and Appeal Board (PTAB).

1. Inter Partes Review (IPR)

• Petitioner: Unified Patents, LLC
• Jurisdiction: USPTO Patent Trial and Appeal Board (PTAB)
• Case Number: IPR2025-01548
• Status: Settled. The records indicate that the parties reached a settlement, which terminated the IPR proceeding before a final written decision on the merits of the patent's validity was issued. The specific terms of the settlement are not publicly available.

This pattern of litigation, targeting major technology companies, combined with a settled IPR challenge, suggests an active and ongoing enforcement campaign by the patent owner, Ingeniospec LLC. The "Expired - Lifetime" status noted in the patent's file wrapper, with an anticipated expiration of July 15, 2025, is a critical factor in all pending cases, as it limits the potential damages period.

Based on my analysis of the U.S. Patent and Trademark Office (USPTO) trial records for U.S. Patent No. 11,829,518, here is a detailed breakdown of the relevant proceedings and their strategic implications for a defendant.

Proceedings overview

There has been one inter partes review (IPR) filed against U.S. Patent No. 11,829,518. This proceeding was terminated via settlement before the Patent Trial and Appeal Board (PTAB) could rule on the merits, meaning none of the patent's claims have been invalidated or confirmed as patentable through an AIA trial. For a defendant, this means the patent's validity remains untested at the PTAB, and all claims are presumptively valid, but the prior art and arguments from the settled IPR are available for use in a new challenge.

IPR2025-01548 — Bose Corporation v. Ingeniospec LLC

• Type: Inter Partes Review (IPR)
• Filed: 2025-09-19
• Status: Terminated-Settled. The parties reached a settlement, and the proceeding was terminated on 2025-11-18 before the PTAB issued an institution decision or a Final Written Decision.
• Judge panel: A panel was likely assigned, but because the proceeding was terminated pre-institution, the names of the Administrative Patent Judges (APJs) may not have been made public in a substantive order.
• Petition grounds: I do not have access to the specific IPR petition, but a petition would have been filed on grounds of anticipation (§ 102) or obviousness (§ 103) based on prior art patents and printed publications. It would have challenged a specific set of claims from U.S. Patent No. 11,829,518.
• Institution decision: Not issued. The proceeding was terminated just two months after filing, well before the six-month deadline for the PTAB to decide whether to institute a trial. The early settlement prevented the Board from ever making a preliminary determination on the merits of the challenge.
• Final Written Decision: Not issued. Since the trial was never instituted, no Final Written Decision (FWD) was rendered.
• Settlement / termination: The parties filed a joint motion to terminate the proceeding due to a settlement agreement, which the PTAB granted on 2025-11-18. The specific terms of the settlement are almost certainly confidential.
• Appeal: None. There was no Final Written Decision to appeal to the U.S. Court of Appeals for the Federal Circuit (CAFC).
• Defensive value: While this proceeding did not result in claim cancellation, it provides significant strategic value. The petition filed by Bose Corporation is a public document and effectively provides a roadmap to a potential invalidity case, including prior art references and expert testimony that a well-resourced company found compelling. Because the case was terminated before an FWD, no IPR estoppel applies to Bose or its privies, leaving the door open for future challenges.

Strategic summary

The patent owner, Ingeniospec LLC, has demonstrated a willingness to settle PTAB challenges, at least in the case of IPR2025-01548 filed by Bose. This could suggest a desire to avoid a substantive ruling on the patent's validity.

• Claim Status: All claims of U.S. Patent No. 11,829,518 (including independent claims 1 and 13) remain UNTESTED by the PTAB. No claims have been canceled or sustained in an AIA trial. The patent enjoys its full presumption of validity as issued by the USPTO.

• Estoppel Landscape: Critically, because IPR2025-01548 was terminated before a Final Written Decision was issued, petitioner estoppel under 35 U.S.C. § 315(e) does not attach. This means that Bose, and any real parties-in-interest or privies, are not barred from filing a subsequent IPR on the same or different grounds. For another defendant, this is good news; all prior art grounds remain available for a new IPR petition. The arguments and art raised by Bose are not "burned" and can be reused, potentially with improvements.

• Pattern Signals: The single PTAB filing was by a major operating company, Bose Corporation, which was also sued in district court (Case 1:25-cv-12531). The swift settlement, just two months post-filing, may indicate that the patent owner preferred to settle rather than risk an institution decision, which could be a signal of perceived weakness in the patent. (Note: A discrepancy exists in the provided case data, with one section listing "Unified Patents" as the petitioner. This analysis relies on the canonical data provided, which names "Bose Corporation" as the petitioner for IPR2025-01548.)

Recommended next steps

For any company currently facing an assertion of U.S. Patent No. 11,829,518, the following steps are recommended:

1. Obtain the Complete File Wrapper for IPR2025-01548: Immediately download the petition and all associated exhibits from the USPTO's PTAB E2E portal. This file contains the prior art, claim charts, and expert declaration (if any) that Bose used to attack the patent. It is, in effect, a "starter kit" for an invalidity defense.

2. Analyze the Petitioner's Arguments: Conduct a thorough analysis of Bose's invalidity contentions. Evaluate the strength of the cited prior art and determine if the arguments can be improved upon or supplemented with new art. The fact that Ingeniospec settled quickly may suggest these arguments had merit.

3. Consider a New IPR Petition: Because no estoppel exists from the prior IPR, filing a new IPR remains a powerful defensive option. A new petition could reuse the best arguments from the Bose filing and add any stronger prior art located during your own search. This strategy would place renewed pressure on the patent owner and could lead to a favorable settlement or a final decision invalidating the asserted claims.

4. Monitor Pending Litigation: Closely watch the dockets for the pending district court cases. Invalidity contentions and expert reports filed in those cases will become public and may reveal additional defensive strategies and prior art.

NPE / troll-pattern signals

1. Shell-entity transfer — unclear. While Ingeniospec LLC is actively involved in litigation, the provided patent document does not contain information about whether it ships products, its registered-agent address, or its corporate structure (e.g., single-member LLC) to definitively classify it as a shell entity.
2. Known asserter in the chain — unclear. Ingeniospec LLC is not identified as a known high-frequency plaintiff on the public NPE lists referenced (Acacia Research Corp, Marathon Patent Group, Intellectual Ventures, etc.) in the provided context, nor is there external search data to confirm. However, the litigation activity suggests it is an asserting entity.
3. Repeat correspondent across the chain — not present. As no assignments are recorded for this patent, there is no chain of correspondents to evaluate for recurrence.
4. Cascading transfers — not present. No assignments are recorded for this patent.
5. Pre-litigation transfer — not present. No assignments are recorded for this patent. Ingeniospec LLC filed the application and is recorded as the original assignee.
6. Bankruptcy fire-sale — not present. No records indicate a bankruptcy-related transfer for Ingeniospec LLC.
7. Privateering — unclear. The patent document does not provide information to determine if Ingeniospec LLC is asserting on behalf of an operating company.
8. Defensive aggregator (anti-NPE) — not present. The patent is held by Ingeniospec LLC and is being asserted in litigation, which is the opposite of being held by a defensive aggregator.

Verdict

NPE — moderate confidence

The confidence for NPE classification is moderate because Ingeniospec LLC is actively asserting this patent against multiple major technology companies (Apple, Meta, Amazon, Snap, Bose) in district court litigation, as detailed in the litigation summary. This pattern of assertion, combined with the lack of information in the patent document indicating product sales or a clear operating business, suggests a primary focus on licensing and enforcement. However, without concrete evidence such as a registered-agent address or a confirmed single-purpose LLC status, it cannot be classified as "high confidence" based solely on the provided internal data.

Here is an analysis of the most relevant prior art for U.S. Patent No. 11,829,518, based on the references cited during its prosecution as available on Google Patents. Many of these citations are part of the same patent family, meaning they share common inventive subject matter and priority claims. While within a patent family, an earlier patent may not strictly be "prior art" under 35 U.S.C. § 102 to a later-filed application if the later application claims valid priority to the earlier one, for the purpose of identifying potential anticipation, this analysis assumes the technical disclosure of the cited patent is compared against the claims of U.S. Patent No. 11,829,518.

The independent claims of U.S. Patent No. 11,829,518 are:

• Claim 1: "A pair of glasses for a user, comprising: an eyewear frame; a first switch at the frame, the first switch having at least two operational states, and the operational states of the switch being configured to be changed by a user touching a surface of the frame, without moving any mechanical part at least partially exposed to the outside of the frame; and a first electrical component in the frame configured to be electrically coupled to the first switch to perform a function."
• Claim 13: "A pair of glasses for a user, comprising: an eyewear frame; electrical circuitry at least partially in the eyewear frame; and a touch sensitive input surface on the eyewear frame configured to provide an input to the electrical circuitry to perform a function via touching the touch sensitive input surface."

Based on the abstracts, the following cited patents are highly relevant as they explicitly disclose the core features of claims 1 and 13.

Most Relevant Prior Art References

1. U.S. Patent No. 7,500,747 (US7500747B2)

• Full Citation: U.S. Patent No. 7,500,747 B2, titled "Head-worn device with connection region," issued March 10, 2009, to inventors Thomas A. Howell, David Chao, C. Douglass Thomas, and Peter P. Tong, and assigned to Ingeniospec LLC.
• Publication/Filing Date: Filed July 15, 2005; Issued March 10, 2009.
• Brief Description: The abstract describes "A pair of glasses with one or more embedded or partially embedded electrical components. In one embodiment, a touch sensitive input surface on the eyewear frame is configured to provide an input to the electrical circuitry to perform a function via touching the touch sensitive input surface. In another embodiment, a switch at the frame has at least two operational states, and the operational states of the switch are configured to be changed by touching a surface of the frame, without moving any mechanical part at least partially exposed to the outside of the frame. The switch is electrically coupled to a first electrical component in the frame configured to perform a function."
• Potential Anticipation under 35 U.S.C. § 102: This patent's abstract directly and explicitly describes all elements of both independent Claim 1 and independent Claim 13 of U.S. Patent No. 11,829,518. Therefore, US7500747B2 potentially anticipates Claims 1 and 13.

2. U.S. Patent No. 7,806,525 (US7806525B2)

• Full Citation: U.S. Patent No. 7,806,525 B2, titled "Eyeglass frame with electrical components," issued October 5, 2010, to inventors Thomas A. Howell, David Chao, C. Douglass Thomas, and Peter P. Tong, and assigned to Ingeniospec LLC.
• Publication/Filing Date: Filed October 11, 2006; Issued October 5, 2010.
• Brief Description: The abstract states, "An eyewear for a user includes an eyewear frame, a first switch at the frame, the first switch having at least two operational states, and the operational states of the switch being configured to be changed by a user touching a surface of the frame, without moving any mechanical part at least partially exposed to the outside of the frame, and a first electrical component in the frame configured to be electrically coupled to the first switch to perform a function. In another embodiment, an eyewear for a user includes an eyewear frame, electrical circuitry at least partially in the eyewear frame, and a touch sensitive input surface on the eyewear frame configured to provide an input to the electrical circuitry to perform a function via touching the touch sensitive input surface."
• Potential Anticipation under 35 U.S.C. § 102: Similar to US7500747B2, this patent's abstract directly and explicitly describes all elements of both independent Claim 1 and independent Claim 13 of U.S. Patent No. 11,829,518. Therefore, US7806525B2 potentially anticipates Claims 1 and 13.

3. U.S. Patent No. 6,882,290 (US6882290B2)

• Full Citation: U.S. Patent No. 6,882,290 B2, titled "Method and apparatus for facilitating control of portable electronic device functions by interaction between the portable electronic device and a user's eyeglasses," issued April 19, 2005, to inventors Thomas A. Howell and Peter P. Tong, and initially assigned to Oakley, Inc., then later to Ingeniospec LLC.
• Publication/Filing Date: Filed October 12, 2004; Issued April 19, 2005.
• Brief Description: The abstract discloses: "A portable electronic device and a user's eyeglasses are configured to interact with each other to facilitate the control of at least one function of the portable electronic device. The eyeglasses include an electrical component (e.g., a speaker) that is electrically coupled to the portable electronic device when the portable electronic device and the eyeglasses are coupled together (e.g., via a connector). The eyeglasses may also include a sensor (e.g., touch-sensitive switch) that allows the user to interact with the eyeglasses to control a function of the portable electronic device."
• Potential Anticipation under 35 U.S.C. § 102:
  • Claim 1 (US11829518): This patent discloses an "eyeglass" (eyewear frame), an "electrical component (e.g., a speaker)" in the frame, and a "touch-sensitive switch" on the eyeglasses to control a function. While the abstract does not explicitly state "without moving any mechanical part at least partially exposed to the outside of the frame," the nature of a "touch-sensitive switch" inherently suggests operation without mechanical movement. The full specification would likely confirm this detail. Thus, US6882290B2 potentially anticipates Claim 1.
  • Claim 13 (US11829518): This patent discloses "eyeglasses" (eyewear frame) with "electrical component" (electrical circuitry) and a "touch-sensitive switch" (touch sensitive input surface) to control a function. This aligns with the elements of Claim 13. Thus, US6882290B2 potentially anticipates Claim 13.

Relationship to U.S. Patent No. 11,829,518:

It is important to note that U.S. Patent No. 11,829,518 claims a priority date of July 28, 2004, and specifically claims priority to several earlier U.S. applications, including U.S. application Ser. No. 11/183,256 (which matured into US7500747B2) and U.S. application Ser. No. 11/546,685 (which matured into US7806525B2). This indicates that US11829518 is a continuation of, or otherwise related to, these earlier patents. The shared inventorship and assignee further reinforce this family relationship.

While these patents appear to anticipate the claims of U.S. Patent No. 11,829,518 based on their disclosures, their status as "prior art" for a 35 U.S.C. § 102 anticipation challenge against US11829518 would depend on whether the claims of US11829518 are entitled to a priority date that predates these references, or if there are any priority breaks or new matter introduced. Nevertheless, their explicit descriptions make them highly relevant for understanding the scope of the invention and its development over time.

Based on the provided patent text for U.S. Patent No. 11,829,518 and the explicit instruction to "Use the results from the Prior Art section of this page," a direct analysis of obviousness under 35 U.S.C. § 103 by combining specific prior art references cannot be fully completed. The "Prior art" section in the provided context only lists "Prior art keywords" (glasses, head, electronic apparatus, wireless electronic, user) and a "Prior art date" of July 28, 2004. It does not provide specific patent numbers or publications as prior art references that can be combined.

However, I can outline the key elements of the independent claims and discuss, conceptually, what types of prior art would be necessary to render these claims obvious, along with the likely motivations for combination, assuming such references existed before the priority date of July 28, 2004.

Independent Claims to be Analyzed:

• Claim 1: A pair of glasses comprising: a frame; a first switch at the frame, the first switch having at least two operational states, wherein the operational states of the switch are configured to be changed by a user touching a surface of the frame, without moving any mechanical part at least partially exposed to the outside of the frame; and a first electrical component in the frame configured to be electrically coupled to the first switch to perform a function.
• Claim 13: A pair of glasses comprising: an eyewear frame; electrical circuitry at least partially in the eyewear frame; and a touch sensitive input surface on the eyewear frame configured to provide an input to the electrical circuitry to perform a function via touching the touch sensitive input surface.

The core inventive concepts in these claims revolve around integrating electrical components into glasses frames and, critically, controlling them via touch-sensitive surfaces directly on the frame, without reliance on visible or movable mechanical parts.

Conceptual Obviousness Analysis (assuming existence of relevant prior art):

To establish obviousness for claims 1 and 13, a combination of prior art references would typically need to disclose the following elements, and a person having ordinary skill in the art (PHOSITA) would need a motivation to combine them:

Hypothetical Prior Art Combination:

1. Primary Reference (e.g., Reference A): A document disclosing a "head-worn device" or "glasses" (as per prior art keywords) that includes an "electronic apparatus" or "electrical component."

   • This reference would establish the general concept of incorporating electronics into eyewear. The patent's background itself acknowledges the existence of "head-sets" for mobile phones, which function as "head-worn device[s]" and contain "electrical components" like speakers and microphones. The patent also notes that "the present invention provides a pair of glasses with one or more embedded or partially embedded electrical components."

2. Secondary Reference (e.g., Reference B): A document disclosing "touch-sensitive input surfaces" (as per claim 13) or "switches" operable by touching a surface "without moving any mechanical part" (as per claim 1) for controlling electronic devices.

   • This reference would demonstrate the state of touch-sensitive technology prior to July 28, 2004. Touchpads on laptop computers and early touchscreens were known technologies. Reference B would teach the general principle of using capacitive, resistive, or other non-mechanical touch sensors for user input.

Motivation to Combine:

A PHOSITA, considering the state of the art before July 28, 2004, would likely have been motivated to combine these hypothetical references for several reasons:

• Improved Aesthetics and Form Factor: Integrating electronic components into eyeglasses inherently aims for a more compact and less obtrusive "head-worn device." Mechanical buttons or switches can interrupt the sleek design of eyewear. Replacing them with touch-sensitive surfaces would offer a cleaner, more integrated appearance, consistent with the design goals of wearable technology.
• Enhanced User Experience (Hands-Free Operation): The patent itself highlights the problem with mobile phones, where "the user has difficultly interacting with the keypad or screen of the mobile phone when the mobile phone is held against the user's head." The desire for hands-free interaction with electronic devices, especially those worn on the head, would naturally lead a PHOSITA to explore intuitive control mechanisms. Touch-sensitive controls on the frame of glasses would provide a convenient and discreet way for a "user" to interact with embedded electronics without requiring visual attention or complex manipulations.
• Durability and Weather Resistance: Mechanical switches often have openings that can be susceptible to dust, moisture, or wear and tear. Touch-sensitive surfaces, especially those integrated seamlessly into the frame, can improve the durability and resistance of the "electronic apparatus" to environmental factors.
• Technological Feasibility: Given that touch-sensitive input technology was already established in other consumer electronics by 2004, a PHOSITA would recognize the technical feasibility of adapting such technology for smaller, integrated applications like eyewear. The "electrical circuitry" and "switch" could be fabricated using known methods (e.g., printed circuit boards, flexible circuits) to fit within the "eyewear frame."

Conclusion on Obviousness based on provided information:

While the provided "Prior art" section does not furnish specific prior art documents, the conceptual analysis suggests that if prior art existed before July 28, 2004, that separately taught:

1. A head-worn device (e.g., glasses) with integrated electrical components (e.g., speakers, microphones, or other functions mentioned in the patent such as MP3 players or cameras).
2. Electronic devices controlled by touch-sensitive interfaces that operate without external mechanical movement.

Then, a PHOSITA would have been motivated to combine these elements to create a more aesthetically pleasing, user-friendly, and durable head-worn electronic device with integrated and discreet controls. The motivations would stem from known desires in the art for miniaturization, hands-free operation, and sleek design in consumer electronics.
