Proceedings overview

US patent 11995685 has been subject to one AIA trial proceeding, IPR2026-00098, which resulted in a denial of institution. This means that no claims of the patent have been invalidated or sustained by the PTAB through a full trial. The patent has successfully defended against an Inter Partes Review challenge at the preliminary stage, giving a defendant a moderately hardened defensive posture against future IPRs, particularly on similar grounds or by the same petitioner.

IPR2026-00098 — Google LLC v. Secure Communication Technologies LLC

• Type: Inter Partes Review
• Filed: 2025-11-11
• Status: Institution Denied. The PTAB declined to institute the Inter Partes Review trial, meaning the proceeding did not advance to a full merits review.
• Judge panel: The specific judge panel for IPR2026-00098 is not publicly available without the official institution decision document.
• Petition grounds: The specific claims challenged, prior art references, and statutory bases (§ 102 / § 103 / § 112) are not publicly available without the official institution decision document for this specific IPR. However, IPRs typically challenge claims based on §§ 102 and 103.
• Institution decision: Denied. The petition for IPR was denied institution. While the precise reasoning for this specific IPR (IPR2026-00098) requires access to the official decision, it is highly likely that the denial was based on the evolving discretionary denial policies of the USPTO Director, particularly given the proximity in time and sequence to the precedential Magnolia Medical Technologies, Inc. v. Kurin, Inc. decision (IPR2026-00097) issued on May 14, 2026. This policy emphasizes that AIA reviews are intended as an alternative, not an expansion, of district court litigation, and may deny institution if the petitioner has already litigated similar validity grounds in district court and lost. Other factors for discretionary denial include serial petitions, parallel litigation, and "settled expectations". The "last modified" date for IPR2026-00098 is May 23, 2026, indicating a decision was likely rendered around that time.
• Final Written Decision: Not applicable, as institution was denied.
• Settlement / termination: Not applicable, as institution was denied.
• Appeal: Not applicable, as institution was denied.
• Defensive value: The denial of institution for IPR2026-00098 means that the patent owner, Secure Communication Technologies LLC, successfully fended off this challenge at an early stage. This outcome generally makes it more challenging for Google LLC (or parties in privy with them) to mount future IPR challenges against US11995685 on similar grounds, especially if the denial was based on discretionary factors related to prior litigation.

Strategic summary

All claims of US11995685 remain active and have not been tested on their merits at the PTAB. The patent has not been narrowed through Inter Partes Review, and all claims are currently sustained from a PTAB perspective.

Regarding the estoppel landscape, since institution of IPR2026-00098 was denied, statutory estoppel under 35 U.S.C. § 315(e)(2) does not formally apply to Google LLC or its privies for any grounds raised or that reasonably could have been raised in that petition. However, the Director's increased use of discretionary denials, particularly those based on the Fintiv factors (related to parallel litigation) or the broader public interest, suggests that a petitioner like Google LLC might face similar discretionary denials if they file subsequent petitions on similar grounds, especially if the underlying reasons for the denial of IPR2026-00098 involved prior district court litigation or other policy considerations now formalized by the Director. This effectively creates a common law or policy-based hurdle for repeat challenges.

The denial of IPR2026-00098 by Google LLC aligns with a broader pattern signaling a more patent-owner-friendly posture at the PTAB in early 2026. The USPTO Director, John Squires, has issued precedential decisions and memoranda reshaping the landscape for AIA trials, emphasizing that the PTAB should serve as an alternative to, not an expansion of, district court litigation. This policy shift means that petitioners may find it harder to institute IPRs, especially if they have engaged in prior validity challenges in other forums or if the challenge does not align with the Office's public interest considerations, such as favoring U.S. manufacturing or settled expectations.

Recommended next steps

Given the institution denial for IPR2026-00098, it is strongly recommended that a defendant facing assertion of US11995685 obtain and thoroughly review the official Institution Decision document for IPR2026-00098. This document will provide the precise claims challenged, the specific prior art asserted, the petitioner's detailed grounds for unpatentability, the PTAB panel assigned, and the exact reasoning for the denial of institution. Understanding these details is crucial for assessing the strength of the patent and informing any future defensive strategies, as the specific reasoning for denial will dictate the extent to which common law estoppel or Director discretion might apply to future challenges.

As of today, May 26, 2026, there are no active PTAB proceedings pending against US patent 11995685. The absence of further PTAB activity after a denial suggests that the patent owner currently holds a strong position against immediate IPR challenges based on the grounds presented in IPR2026-00098.

Inventors

• James A. Proctor, Jr.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. Proxicom Wireless LLC and Secure Communication Technologies LLC do not appear to have commercial products embodying the claims and primarily engage in patent-related activities, which is characteristic of shell entities used for licensing or assertion. [cite: Reel 062835/0074, Reel 064619/0430]
2. Known asserter in the chain — Unclear. Neither Proxicom Wireless LLC nor Secure Communication Technologies LLC are explicitly listed among common public NPE lists. However, Google Patents indicates active litigation related to this patent, including a PTAB IPR (IPR2026-00098) and a US district court case in Texas Western District Court (1:25-cv-01579), suggesting active assertion by the current assignee.
3. Repeat correspondent across the chain — Present. Brent D. Landers of Landers & Partners, PLLC, is the correspondent of record for two assignments: Reel 062835/0074 (2024-04-10) and Reel 064619/0430 (2025-07-15). Both involve Secure Communication Technologies LLC as the assignee, indicating a consistent legal representative for the asserting entity. [cite: Reel 062835/0074, Reel 064619/0430]
4. Cascading transfers — Present. There are three assignments recorded within a 15-month period (April 2024 to July 2025). The pattern involves a transfer from Proxicom Wireless LLC to Secure Communication Technologies LLC, followed by an inventor assignment to Proxicom Wireless LLC, and then a re-transfer from Proxicom Wireless LLC back to Secure Communication Technologies LLC. This rapid sequence of transfers, particularly with the same correspondent for the transfers involving Secure Communication, suggests an orchestrated strategy. [cite: Reel 062835/0074, Reel 064379/0471, Reel 064619/0430]
5. Pre-litigation transfer — Present. The last assignment to Secure Communication Technologies LLC was recorded on 2025-07-15 (Reel 064619/0430). Google Patents indicates a US district court case was filed in 2025 (case 1:25-cv-01579), which suggests the assignment occurred within months of the litigation filing. [cite: Reel 064619/0430, 1]
6. Bankruptcy fire-sale — Not present. No evidence suggests any entity in the chain underwent bankruptcy proceedings.
7. Privateering — Unclear. There is no public information or SEC filings available to suggest that an operating company transferred the patent to an NPE to assert on its behalf against competitors.
8. Defensive aggregator (anti-NPE) — Not present. The current assignee, Secure Communication Technologies LLC, is not a known defensive aggregator.

Verdict

NPE — high confidence. The presence of shell-entity transfers, cascading transfers within a short timeframe (15 months), and a repeat correspondent for the transfers involving Secure Communication Technologies LLC strongly indicate an NPE assertion strategy. The recorded litigation further confirms active assertion of this patent in district court and PTAB. [cite: Reel 062835/0074, Reel 064379/0471, Reel 064619/0430, 1]

Let's start by searching for US11995685 and its claims.
Then, I will look for its cited prior art.## Most Relevant Prior Art for US Patent 11995685

To identify the most relevant prior art for US Patent 11995685, we will examine the patent citations listed within the patent document itself. The following analysis is based on the information available from the full patent text provided in the user message, which includes details often found on Google Patents.

As the provided patent text does not explicitly list the "Claims" section, I will make an inference based on the "Abstract" and "Summary" sections of the patent regarding what the patent broadly claims. Without direct access to the numbered claims, it is not possible to specify which numbered claim each prior art reference anticipates. Instead, I will discuss the general inventive concept it might anticipate.

The patent US11995685 focuses on a system and method for:

1. Reducing communication between servers and mobile devices: achieved by a mobile device filtering beacon transmissions locally using a beacon service identifier before interacting with a server.
2. Enhancing security and privacy for wireless beacon services: achieved by using unique identifiers, MAC addresses, and coordinating identifier changes with a central server to maintain anonymity over time.
3. Facilitating information exchange and transactions (e-commerce, content delivery) via a central server: where a short-range wireless link is used for detection, and a wide-area wireless network (WWAN) is used for substantive communication with a server that manages policies, content delivery, and transactions.

The "Prior art keywords" section on Google Patents for US11995685 lists: "beacon," "wireless device," "unique identifier," "further action," and "identifier." The "Prior art date" is listed as 2008-09-08.

The "Background" section of US11995685 references previous approaches and explicitly mentions one: "Published US Patent application US 2008/0182591 A1 filed Dec. 13, 2007 describes one such peer to peer approach." This suggests US 2008/0182591 A1 is a key piece of prior art.

Analysis of Cited Prior Art

Based on the patent's "Background" section, the most directly referenced prior art is:

1. US Patent Application US 2008/0182591 A1

• Full Citation: US 2008/0182591 A1
• Publication/Filing Date:
  • Publication Date: Not explicitly stated in the provided text, but it's "Published US Patent application US 2008/0182591 A1".
  • Filing Date: December 13, 2007 (as stated in the background section of US11995685).
• Brief Description: US11995685 describes US 2008/0182591 A1 as an example of a "peer to peer approach" to mobile networking, where software applications on mobile phones use peer-to-peer networks (like Wi-Fi or Bluetooth) to facilitate communication between wireless devices. The problem identified with these approaches is that "all information to be exchanged must be stored locally on each of the peer devices as the communication occurs directly between the two devices and any policy for the delivery of locally stored content is difficult to enforce without the potential for fraud such as spoofing identities between the peers. Such fraud may lead to concerns of personal safety or privacy allowing the identity of an individual to be determined when it is not desired."
• Which claim(s) it potentially anticipates under 35 U.S.C. § 102:
  Given the description in US11995685, US 2008/0182591 A1 likely anticipates general concepts related to peer-to-peer communication between wireless devices using short-range wireless technologies (e.g., Bluetooth, Wi-Fi) for detection and subsequent data exchange. It particularly highlights the challenge of enforcing policy and preventing identity spoofing in such pure peer-to-peer systems. Therefore, any claims in US11995685 that broadly cover merely detecting other devices via short-range wireless and then communicating, without the specific intermediary role of a central server for policy enforcement, information brokering, dynamic identifier management, or separation of detection and communication channels, would potentially be anticipated by US 2008/0182591 A1. Specifically, claims that focus solely on the "detection of one device by another via a short-range wireless link" might be implicated. However, the inventive steps of US11995685, which emphasize the use of a central server to manage information exchange, policy, and dynamically changing identifiers, distinguish it from the peer-to-peer approach described for US 2008/0182591 A1.

Without the specific claims of US11995685, it is difficult to state definitively which claims are anticipated. However, the patent itself defines its distinguishing features from this prior art. The key distinctions US11995685 points out are:

• The use of a central server to manage the exchange of information and application data flow, rather than direct peer-to-peer exchange over the short-range link.
• The central server's role in brokering services, applying policy for information disclosure, and enabling security verification.
• The ability to use dynamically changing wireless identifiers coordinated with a central server to enhance security and anonymity, which is difficult in a true peer-to-peer topology if the identifier (like a MAC address) is static.
• The separation of the short-range link for detection only and the wide-area network for substantive communication.

Therefore, any claims of US11995685 that specifically incorporate these distinguishing features would likely not be anticipated by US 2008/0182591 A1 based on the patent's own description.I have accessed the full patent text for US11995685, "Efficient and secure communication using wireless service identifiers," from the provided Google Patents link.

Most Relevant Prior Art for US11995685

Based on the patent text and external information, here is an analysis of the most relevant prior art. The patent itself highlights US 2008/0182591 A1 in its background section as a representation of existing peer-to-peer approaches.

1. US Patent Application US 2008/0182591 A1

• Full Citation: US 2008/0182591 A1 to Balakrishnan et al.

• Publication/Filing Date:

  • Publication Date: July 31, 2008
  • Filing Date: December 13, 2007 (as stated in the background section of US11995685)

• Brief Description: As described in US11995685, this patent application generally describes mobile networking services that utilize short-range wireless capabilities (e.g., Wi-Fi or Bluetooth) to facilitate peer-to-peer communications between wireless devices. It focuses on software applications operating on mobile phones to establish Mobile Ad-hoc Networks (MANETs). The primary concern raised by US11995685 regarding this prior art is the difficulty in enforcing policy for locally stored content and preventing fraud (like spoofing identities) due to the direct peer-to-peer communication model without a central arbiter.

• Which claim(s) it potentially anticipates under 35 U.S.C. § 102:
  Given the description provided in US11995685, US 2008/0182591 A1 potentially anticipates aspects of US11995685's claims that broadly cover detection of wireless devices via short-range radio and subsequent communication between devices. More specifically, if any part of the claims in US11995685 is interpreted to cover solely peer-to-peer discovery and direct communication between devices using short-range wireless, without the critical involvement of a central server for brokering, policy enforcement, or dynamic identifier management, then those broad aspects could be anticipated.

  • Claim 1 (Method): The general concept of "transmitting... a first beacon transmission" (1a) and "receiving... a first plurality of beacon transmissions" (1b) using a short-range wireless radio, if isolated from the subsequent server interaction and filtering steps, might be broadly anticipated. However, the subsequent steps (1c-1e) that involve receiving "stored information relating to an entity or object associated with the first unique identifier" from "one or more servers using a second radio," and then filtering based on a "beacon service identifier" to take "further action" using this server-provided information, distinctly differentiate Claim 1 from a pure peer-to-peer system.
  • Claim 11 (System): Similar to Claim 1, the components for transmitting and receiving beacon transmissions (11a, 11bi) could be broadly anticipated in isolation. However, the configuration for interacting with "one or more servers using a second radio" to receive "stored information" (11bii) and then using this server-provided information to take "further action" (11biii, 11biv) distinguishes Claim 11.
  • Claim 18 (Method): This claim involves a "first wireless device" receiving an identifier from a "second wireless device" (18a, 18b). The crucial differentiating steps are "the first wireless device requesting information from the server associated with the first wireless identifier" (18c) and "the server providing different amounts of information related to the first account based on the parameters associated with one or both of the first and second accounts" (18e). These server-centric information exchange and policy application aspects would likely not be anticipated by a purely peer-to-peer system as described for US 2008/0182591 A1.

  In essence, US 2008/0182591 A1 lays the groundwork for proximate device discovery and communication, but US11995685 argues its novelty by introducing a central server as a secure and policy-enforcing intermediary, a concept not adequately addressed by the peer-to-peer systems mentioned.

Note on Additional Prior Art:
The provided patent text in the user's prompt did not include a formal "References Cited" section, which typically lists all prior art considered by the examiner. The only explicit prior art mentioned within the descriptive text was US 2008/0182591 A1. To provide a comprehensive list of all cited prior art, a direct examination of the full patent document from the USPTO or Google Patents "References Cited" section would be necessary. My analysis focuses on the one explicit reference given in the provided authoritative patent text.

A proper obviousness analysis under 35 U.S.C. § 103 requires identifying specific prior art documents that disclose the elements of the claims and then articulating a reason why a person having ordinary skill in the art (POSA) would have been motivated to combine or modify those references to arrive at the claimed invention.

The provided "Prior art keywords" (beacon, wireless device, unique identifier, further action, identifier) found on the Google Patents page for US11995685 are descriptive terms associated with the patent, but they do not constitute specific prior art references (e.g., other patents, publications) that can be individually analyzed and combined.

However, the "BACKGROUND" section of US11995685 explicitly identifies and discusses one prior art reference:

• US 2008/0182591 A1: This published US patent application, filed December 13, 2007, describes a "peer to peer approach" to mobile networking, utilizing short-range wireless capabilities (like Wi-Fi or Bluetooth) for communication between wireless devices, also referred to as Mobile Ad-hoc Networks (MANETs). [cite: BACKGROUND]

The patent US11995685 itself highlights the "issue with these approaches [peer-to-peer]" as: "all information to be exchanged must be stored locally on each of the peer devices as the communication occurs directly between the two devices and any policy for the delivery of locally stored content is difficult to enforce without the potential for fraud such as spoofing identities between the peers. Such fraud may lead to concerns of personal safety or privacy allowing the identity of an individual to be determined when it is not desired." [cite: BACKGROUND]

Given this context, a hypothetical obviousness argument could be constructed by combining the teachings of US 2008/0182591 A1 with general knowledge in the art, motivated by the identified problems in the prior art.

Obviousness Analysis based on US 2008/0182591 A1 and General Knowledge:

Primary Reference: US 2008/0182591 A1 (describes peer-to-peer mobile ad-hoc networks using short-range wireless for device communication). [cite: BACKGROUND]

Claimed Features of US11995685 (from Abstract and Detailed Description):
The core method of US11995685 involves:

1. A beacon transmitter using a short-range wireless radio to transmit a beacon, including a MAC address, a unique identifier, and a beacon service identifier. [cite: Abstract]
2. A wireless device receiving these beacons. [cite: Abstract]
3. The wireless device selecting unique identifiers by filtering for the beacon service identifier. [cite: Abstract]
4. The wireless device taking further action based on a detected unique identifier, using stored information from one or more servers (which may be pre-downloaded or requested via a second, wide-area wireless radio). [cite: Abstract]
5. A central server managing the exchange of information, enforcing policy, and potentially coordinating dynamic changes to identifiers for enhanced security and privacy. [cite: Abstract, SUMMARY]
6. The short-range wireless is primarily for detection or advertising presence, with substantive communication occurring via a wide-area wireless network (WWAN) to the central server. [cite: Detailed Description]

Motivation for Combining and Modification:

A person of ordinary skill in the art (POSA), upon reviewing a peer-to-peer system like that described in US 2008/0182591 A1, and recognizing its limitations regarding policy enforcement, fraud prevention, and privacy (as explicitly identified in US11995685's background [cite: BACKGROUND]), would have been motivated to incorporate elements of well-known client-server architectures to overcome these deficiencies.

1. Introducing a Central Server for Brokering and Policy Enforcement: The most significant distinction of US11995685 is the reliance on a central server to broker interactions, store entity accounts, and enforce policies. [cite: SUMMARY] Centralized servers for managing user identity, access control, and content delivery were (and are) a fundamental aspect of internet-based services (e.g., social media, e-commerce, content platforms). A POSA, facing the "difficulty to enforce without the potential for fraud such as spoofing identities" [cite: BACKGROUND] in a pure peer-to-peer system, would have found it obvious to introduce a trusted third party (a central server) to:

   • Manage user accounts and identities: Store personal information, contact details, social network links, and communication preferences. [cite: Detailed Description]
   • Enforce policy: Determine what information is disclosed to whom, under what conditions, based on stored policy permissions associated with accounts. [cite: Detailed Description] This directly addresses the "difficulty to enforce policy" in peer-to-peer systems. [cite: BACKGROUND]
   • Broker communication: Route application data flow through the server via a wide-area network (WWAN), rather than direct peer-to-peer short-range communication. [cite: SUMMARY] This provides a controlled environment for interactions.

2. Using a "Beacon Service Identifier" for Filtering: Given the proliferation of various wireless beacons (Bluetooth, Wi-Fi) for advertising presence, a POSA would recognize the need for efficiency in detecting relevant devices. Transmitting a "beacon service identifier" along with other identifiers (like MAC address or unique ID) in a short-range beacon transmission [cite: Abstract] would be an obvious way to enable a receiving device to quickly filter for beacons pertaining to a specific application or service. This reduces processing overhead on the mobile device and the amount of irrelevant data sent to the central server, an efficiency improvement common in wireless network design. The patent itself states the wireless device "selects one or more unique identifiers from the first plurality of beacon transmissions, by filtering (that is, selecting) only those beacon transmissions which include the beacon service identifier." [cite: Abstract]

3. Dynamically Changing Unique Identifiers for Enhanced Security and Privacy: The background of US11995685 explicitly states that in peer-to-peer approaches, "information related to a user's device must be disclosed in the process of detection in the form of a static identifier. By the nature of the identifier, it must be static or peers would not be able to directly determine the identity of a friend over time with the information stored on their device." [cite: Detailed Description] This leads to "concerns of personal safety or privacy." [cite: BACKGROUND] To counter this, it would be obvious to a POSA to implement dynamically changing identifiers, coordinated by a central server. The server acts as the authoritative source for associating temporary identifiers with persistent user accounts, thereby enhancing anonymity while preserving service functionality. [cite: Detailed Description] Using a randomly generated 48-bit MAC address (like a Bluetooth BD_ADDR) [cite: SUMMARY] as an identifier that changes over time would be a known technique to prevent persistent tracking.

4. "Further Action" using Stored/Pre-downloaded Information to Reduce Server Load: Once a relevant beacon (filtered by service identifier) and its unique identifier are detected, a POSA would be motivated to optimize the subsequent interaction. Having the mobile device take "further action" using "stored information" (either pre-downloaded or retrieved on demand) [cite: Abstract] from the server directly addresses the goal of "reducing communications between one or more servers and a wireless device" [cite: SUMMARY] and improving efficiency. This is analogous to caching or local processing in distributed systems, a routine engineering consideration for performance optimization.

In summary, the specific architecture described in US11995685, which leverages short-range beacons for detection only and then routes substantive, policy-controlled interactions through a central server via a wide-area network, represents an obvious solution to the known problems of security, privacy, and policy enforcement inherent in pure peer-to-peer wireless communication systems like that of US 2008/0182591 A1. The inclusion of beacon service identifiers for filtering, dynamically changing identifiers for anonymity, and local "further action" based on server-provided information are all logical and obvious optimizations or solutions to recognized problems within the field of wireless communication and network services.

A detailed analysis of US Patent 11995685 regarding patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and projected expiration date is provided below.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can add days to the 20-year term of a U.S. patent to compensate for certain delays caused by the USPTO during the patent prosecution process. These delays fall into categories such as:

• Failure to issue an office action within 14 months of filing.
• Failure to respond to a reply or appeal within four months.
• Failure to issue the patent within three years of the application filing date.
• Delays due to interference, secrecy orders, or appellate review.

Applicant delays can, however, reduce the PTA awarded.

To determine the exact PTA for US11995685, one would typically need to consult the "Issue Notification Letter" from the USPTO, which provides the final PTA calculation at the time of patent issuance. Without direct access to the official USPTO Patent Center for US11995685, the specific PTA amount cannot be definitively stated. However, the Google Patents page for US11995685 lists the "Anticipated expiration" date as "2029-02-03". This date is typically calculated from the earliest priority date plus 20 years, with any PTA added.

Given the Filing Date of June 1, 2023, and Issue Date of May 28, 2024, the patent issued in less than one year, which is well within the USPTO's 3-year target for issuing patents. This suggests that significant "B delay" (delays due to application pendency exceeding three years) is unlikely. Any PTA would likely stem from other types of USPTO delays (A, C delays) or be offset by applicant delays.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available for patents claiming products that require regulatory approval from agencies like the FDA (e.g., human drugs, medical devices, food additives, animal drugs). PTE aims to restore patent term lost during the regulatory review period.

US Patent 11995685 relates to "Efficient and secure communication using wireless service identifiers," which falls under the domain of communication technology rather than products requiring regulatory approval. Therefore, it is highly unlikely that US11995685 would be eligible for a Patent Term Extension under 35 U.S.C. § 156.

Continuation Applications, Divisional Applications, and Related Family Members

To identify continuation and divisional applications, as well as other related family members, one typically looks at the "Related U.S. Application Data" or "Continuity Data" section within the patent document or its prosecution history in USPTO Patent Center.

The Google Patents record for US11995685 lists the following "Other versions" and "Priority to" information, which can indicate related applications:

• US20230325881A1 (Publication of US11995685 as an application)
• Priority to US18/204,528 (This is the application number for US11995685)
• Priority to US18/437,306 (Filing date 2024-02-09, patent/US12430667B2/en)
• Priority to US19/027,075 (Filing date 2025-01-17, patent/US20250166009A1/en)
• Priority to US19/027,020 (Filing date 2025-01-17, patent/US20250166008A1/en)

Based on this information:

• US18/204,528 is the original application that led to US11995685.
• US20230325881A1 is the published application for US18/204,528.
• US18/437,306, US19/027,075, and US19/027,020 are subsequent applications that claim priority to an earlier application in the family, making them potential continuation or divisional applications. Without further detail from the prosecution history, it's not possible to definitively classify them as continuations, continuations-in-part, or divisionals, but they are clearly related family members.

Projected Expiration Date

The basic patent term for a U.S. utility patent filed on or after June 8, 1995, is 20 years from its earliest effective filing date. This term can be adjusted by PTA or PTE.

For US11995685:

• Earliest Filing Date: The Google Patents record indicates the priority date is September 8, 2008.
• Base Expiration Date (20 years from priority date): September 8, 2028.
• Anticipated Expiration (from Google Patents): February 3, 2029.

The difference between the base expiration date (September 8, 2028) and the anticipated expiration date (February 3, 2029) is approximately 4 months and 26 days. This difference likely represents the Patent Term Adjustment (PTA) granted to the patent due to USPTO delays during prosecution. Given that the patent was filed on June 1, 2023, and issued on May 28, 2024, it is highly probable that the "priority date" of 2008-09-08 listed on Google Patents refers to an earlier application in a chain of continuing applications, and this earlier date is used to calculate the 20-year term.

Therefore, the projected expiration date for US Patent 11995685 is February 3, 2029.
