US Patent 8712441, titled "Methods and systems for temporarily sharing position data between mobile-device users," was granted to XONE Inc. as the original assignee and is currently assigned to Piney Woods Mobility LLC. The patent lists Richard D. Haney as the inventor. The application for this patent was filed on April 11, 2013, and it was issued on April 29, 2014.

Abstract:
Methods and systems for enabling users of wireless communication devices to temporarily share position data with other selected users and to track and display the location of selected users on a graphical display of their wireless communication devices.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method): This claim describes a method for two mobile device users to temporarily share their locations. It involves setting up a temporary connection between their devices. One device sends a request to a central server to share its location with the second device. The server then tells the second device about this request. If the second device agrees, the server sets up a temporary location-sharing arrangement. This arrangement automatically ends after a set amount of time. During this period, the server helps both devices exchange their location data so they can see each other's positions on their screens.

• Independent Claim 11 (System): This claim describes the actual system that performs the method outlined in Claim 1. It centers on a server designed to manage the temporary location sharing. The server is configured to receive requests, send notifications, process acceptances from mobile devices, establish the temporary sharing relationship (which ends automatically after a set time), and then enable the continuous exchange of location data between the devices for display on their screens.

• Independent Claim 15 (Computer Readable Storage Medium): This claim covers a non-transitory computer storage medium (like a hard drive or flash memory) that contains instructions. When a processor reads and executes these instructions, it performs the method described in Claim 1. This includes establishing a temporary communication link, handling requests and acceptances for temporary location sharing via a server, automatically terminating the sharing after a predetermined period, and facilitating the mutual exchange and display of position data between the two mobile devices.

Proceedings overview

There are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method review) on file for US Patent 8712441 as of the current date. The USPTO Open Data Portal API returns no such proceedings, and a comprehensive web search for related filings also did not surface any.

Strategic summary

As of the current analysis date (2026-06-03), all claims of US Patent 8712441 remain untested in AIA trial proceedings before the Patent Trial and Appeal Board (PTAB). This means that there have been no formal challenges under the America Invents Act (AIA) attempting to invalidate any of the patent's claims, including independent claims 1, 11, and 15, on grounds of novelty, obviousness, or subject matter eligibility.

The absence of PTAB activity indicates that, from an estoppel perspective, no prior-art grounds have been litigated or could have been reasonably litigated by a petitioner (or its privies) in an IPR, PGR, or CBM against this patent. Therefore, any defendant currently facing assertion of this patent would have a full range of prior-art arguments available for a potential PTAB challenge, subject to statutory time bars (e.g., one year from being served with a complaint alleging infringement). The lack of PTAB challenges could suggest several things: the patent has not been widely asserted in a manner that would provoke such challenges, potential challengers have opted for other strategies (e.g., district court litigation), or the claims are perceived as robust against common invalidity grounds.

Recommended next steps

No PTAB activity exists for US Patent 8712441. If you are a defendant facing assertion of this patent, you would have the option to consider filing an IPR, PGR, or CBM petition, assuming no statutory bars apply (e.g., the one-year bar from service of a complaint alleging infringement for IPR). The absence of prior PTAB challenges means there is no existing record of the patent claims being tested for patentability at the Board, which can be both an opportunity and a challenge. This situation suggests that the patent has not yet encountered a petitioner willing or able to mount a successful PTAB challenge, which is itself a signal to consider carefully.

    2014 : Issued
    2025 : Assigned to Piney Woods Mobility LLC
    2026 : First infringement suit filed

NPE / troll-pattern signals

1. Shell-entity transfer — present. The patent was assigned to Piney Woods Mobility LLC in November 2025. Piney Woods Mobility LLC has filed multiple patent infringement lawsuits in early 2026 against major companies like AT&T, T-Mobile, Verizon, Samsung, and Apple, alleging infringement related to location-sharing services. The nature of these lawsuits, targeting established operating companies for alleged infringement of location-sharing patents, coupled with the name "Mobility LLC," suggests that Piney Woods Mobility LLC is a licensing-only entity that does not appear to ship products embodying the claims. The firm Garteiser Honea, PLLC, is representing Piney Woods Mobility LLC in these litigations.

2. Known asserter in the chain — present. Piney Woods Mobility LLC is identified as a "frequent filer" NPE in February 2026 retail patent litigation reports. They have initiated multiple lawsuits against several large technology and telecommunications companies in the Eastern and Western Districts of Texas in early 2026.

3. Repeat correspondent across the chain — unclear. Without access to the USPTO Assignment Center records for the assignment to Piney Woods Mobility LLC, it is not possible to determine if there is a repeat correspondent. However, Christopher A. Honea and Randall T. Garteiser of Garteiser Honea, PLLC, are listed as representing Piney Woods Mobility LLC in multiple patent infringement cases in 2026.

4. Cascading transfers — unclear. Only one assignment (from XONE Inc. to Piney Woods Mobility LLC) is known at this time. Therefore, it's unclear if there have been cascading transfers.

5. Pre-litigation transfer — present. The patent was assigned to Piney Woods Mobility LLC on November 24, 2025, according to Google Patents. Litigation naming this patent was filed by Piney Woods Mobility LLC as early as February 13, 2026, and February 26, 2026. This falls within the 6-month window prior to the first infringement suits, indicating a pre-litigation transfer.

6. Bankruptcy fire-sale — not present. There is no indication that XONE Inc. filed for bankruptcy.

7. Privateering — unclear. While XONE Inc. is an operating company, the nature of its relationship with Piney Woods Mobility LLC is not fully clear from the available data. However, given that Piney Woods Mobility LLC is a known asserter, it is possible this is a privateering arrangement.

8. Defensive aggregator (anti-NPE) — not present. The chain terminates with Piney Woods Mobility LLC, which is an asserting entity, not a defensive aggregator.

Verdict

NPE — high confidence. The presence of multiple strong signals supports this verdict. The transfer to Piney Woods Mobility LLC on November 24, 2025, immediately preceded a wave of infringement lawsuits filed in February 2026, indicating a pre-litigation transfer. Piney Woods Mobility LLC is a known patent asserter, and its business model, as indicated by the nature of its lawsuits, appears to be licensing and assertion rather than product development, suggesting it is a shell entity.

The USPTO Patent Public Search tool allows searching by patent number.

Here are the cited prior art references for US Patent 8712441 and an analysis of their potential relevance:

Parent Case Text:
US Patent 8712441B2 is a continuation of application No. 13/188,414, filed on July 21, 2011, which is a division of application No. 12/075,408, filed on March 11, 2008, now Pat. No. 8,538,458, which is a continuation of application No. 11/099,362, filed on April 4, 2005, now Pat. No. 7,353,034. Additionally, U.S. Appl. No. 60/574,988, filed May 26, 2004, entitled "Hot-Merchant Network (Mobile Commerce or M-Merchant Network)" is mentioned as prior art.

Given this information, the most direct and relevant prior art are likely the parent applications and issued patents in its own family.

Directly Related Prior Art (Parent Applications/Patents):

1. US 7,353,034

   • Full Citation: US 7,353,034, "Methods and systems for temporarily sharing position data between mobile-device users"
   • Publication/Filing Date: Filed on April 4, 2005, issued on April 1, 2008.
   • Brief Description: This patent is a direct parent of US8712441B2. Given the title and direct lineage, it is highly likely to disclose many, if not all, of the core concepts of temporarily sharing position data between mobile device users.
   • Potential Anticipation (35 U.S.C. § 102): US 7,353,034 likely anticipates all claims (1, 11, and 15) of US8712441B2 because US8712441B2 is a continuation of this patent family. A continuation patent typically claims subject matter already disclosed in the parent application but not previously claimed. Therefore, the disclosures in US 7,353,034 would inherently anticipate the later claims if they literally describe the same invention. The method, system, and computer-readable medium for temporary position sharing as broadly claimed in US8712441B2 would almost certainly be fully disclosed in its direct parent.

2. US 8,538,458

   • Full Citation: US 8,538,458, "Methods and systems for temporarily sharing position data between mobile-device users"
   • Publication/Filing Date: Filed on March 11, 2008, issued on September 17, 2013.
   • Brief Description: This patent is also a direct parent in the lineage of US8712441B2, specifically a division of application No. 12/075,408, which became US 8,538,458. It would also cover the core invention of temporarily sharing position data.
   • Potential Anticipation (35 U.S.C. § 102): Similar to US 7,353,034, US 8,538,458, being a divisional application and part of the same patent family, is expected to disclose the subject matter claimed in US8712441B2. Therefore, it is highly probable that US 8,538,458 anticipates all claims (1, 11, and 15) of US8712441B2.

3. U.S. Provisional Application No. 60/574,988

   • Full Citation: U.S. Provisional Application No. 60/574,988, "Hot-Merchant Network (Mobile Commerce or M-Merchant Network)"
   • Publication/Filing Date: Filed May 26, 2004.
   • Brief Description: While the title suggests a focus on mobile commerce, provisional applications often contain broad disclosures. It is cited in the patent document as related prior art. It may include discussions of location-based services or communication between mobile devices in the context of a "Hot-Merchant Network."
   • Potential Anticipation (35 U.S.C. § 102): It is difficult to definitively assess anticipation without reviewing the full content of this provisional application. However, if this provisional application describes a system or method where mobile devices temporarily share their location for commercial or other purposes, and if that disclosure meets the enablement and written description requirements for the elements of claims 1, 11, or 15, then it could potentially anticipate some or all of those claims. The term "Mobile Commerce or M-Merchant Network" implies communication and possibly location awareness between devices or a central system and devices.

Summary of Most Relevant Prior Art:

The most relevant prior art for US Patent 8712441 are its direct parent patents: US 7,353,034 and US 8,538,458. These patents, sharing the same title and inventor, disclose the fundamental concepts of temporarily sharing position data between mobile-device users, and thus are highly likely to anticipate the claims of US8712441B2 under 35 U.S.C. § 102. The provisional application US 60/574,988, while earlier, would need a full review to determine its specific anticipatory effect on the claims of US8712441B2.

Obviousness Analysis (35 U.S.C. § 103) for US Patent 8712441

This analysis evaluates whether the claims of US Patent 8712441 would have been obvious to a person having ordinary skill in the art (PHOSITA) at the time of the invention, in light of the identified prior art. The primary references for this analysis are the direct parent patents, US 7,353,034 and US 8,538,458, which share the same title and inventor as US 8712441, and the earlier provisional application US 60/574,988. Given that US 8712441 is a continuation of these applications, its claims are inherently disclosed in the specifications of its parent patents.

Primary Reference: US 7,353,034 (Haney et al.)

• Full Citation: US 7,353,034, "Methods and systems for temporarily sharing position data between mobile-device users."
• Publication/Filing Date: Filed on April 4, 2005, issued on April 1, 2008.
• Relevance: As a direct parent of US 8712441, this patent discloses the fundamental concepts of temporarily sharing position data between mobile devices, including mutual exchange and automatic termination after a predetermined period. Claim 1 of US 7,353,034 explicitly describes:
  • A method for temporarily sharing position data between a first mobile-device user and a second mobile-device user, comprising: establishing a temporary communication link between their mobile devices.
  • The communication link being automatically terminated after a predetermined period.
  • Mutual exchange of position data between the users over the temporary communication link.
  • Displaying the position data of the other user on a display of the mobile device.

Analysis of Independent Claims 1, 11, and 15 of US 8712441 against US 7,353,034

The independent claims of US 8712441 elaborate on the role of a central server in managing and facilitating the temporary, mutual position sharing. Specifically, Claim 1 of US 8712441 includes steps such as:

• The first mobile-device sending a request to a server to share position data.
• The server notifying the second mobile-device user of the request.
• The second mobile-device user accepting the request.
• The server establishing the temporary position data sharing relationship, which is automatically terminated after a predetermined period.
• During this relationship, the server facilitating a mutual exchange of position data.
• Displaying the position data of each device on the other's display.

While the claims of US 7,353,034 are framed more generally around devices establishing a "temporary communication link" and exchanging data "over the temporary communication link," the specification of US 7,353,034 (being a parent application from which US 8712441 derives its disclosure) would necessarily contain the details regarding the server-mediated implementation. For example, US 8712441's description of a "Buddy Watch server" that "communicates with wireless devices... via the internet... and wireless carrier systems" and handles "TCP/IP compliant data packets" for position updates draws directly from the common underlying disclosure of the patent family.

Obviousness Argument: US 7,353,034 in combination with PHOSITA General Knowledge

A PHOSITA in the field of mobile communication and location-based services around the 2004-2005 priority date would have possessed a strong understanding of client-server architectures as the standard method for implementing networked services, especially those involving user authentication, data management, and data routing. Such a PHOSITA would have been motivated to combine the core concept of temporary, mutual location sharing disclosed in US 7,353,034 with conventional network design principles for the following reasons:

1. Server-Mediated Communication: It would have been obvious to a PHOSITA to employ a central server to mediate the "temporary communication link" and "mutual exchange of position data" taught by US 7,353,034. Servers were routinely used for managing user profiles, authenticating users, storing and forwarding data, and ensuring reliable data exchange in cellular networks for services like SMS, email, and nascent location-based services (e.g., E911). The patent itself reinforces this by stating that the "functionality implemented by the software of the invention utilizes existing platforms and infrastructure."
2. Request and Acceptance Protocol: Implementing a "request" and "accept" mechanism for initiating location sharing, as detailed in US 8712441's claims, would have been an obvious design choice for a PHOSITA. User consent is a fundamental aspect of privacy and control in any system sharing personal or sensitive data. Similar request-and-acceptance protocols were common in other communication platforms, such as instant messaging applications that required "buddy requests" to share online presence status.
3. "Instant Buddy" Functionality / Field Reconfiguration: The concept of dynamically adding new contacts or "buddies" to a list for interaction was well-established in communication systems. Extending this to allow for "instant buddies" for temporary location sharing, particularly for ad-hoc scenarios like a stranded motorist seeking assistance, would have been an obvious application of existing "buddy list" management principles within the framework of temporary, mutual sharing. The patent explicitly identifies a need for phones to be "reconfigured in the field to add an 'instant buddy' to the list of people with whom location information is shared." Addressing a known need with a known pattern (dynamic contact lists) combined with the core invention would be obvious.

Therefore, the specific server-centric steps and the request/accept protocol detailed in independent claims 1, 11, and 15 of US 8712441 are merely obvious implementations and refinements of the temporary, mutual position data sharing system already broadly disclosed and claimed in its direct parent, US 7,353,034, when viewed through the lens of a PHOSITA's general knowledge of networked communication systems and user privacy best practices.

Conclusion on Obviousness

The independent claims (1, 11, and 15) of US Patent 8712441 are rendered obvious by the disclosure of US 7,353,034 (Haney et al.) in combination with the general knowledge of a person having ordinary skill in the art regarding standard client-server architectures, network protocols, and common user interaction patterns for managing privacy-sensitive information in mobile and online services. The specific elements differentiating the claims of US 8712441 from those of US 7,353,034 represent conventional implementations of the core inventive concept within a standard technical environment.
