Prior art

To search the USPTO database for patent 11864641, I would use the Patent Public Search tool, specifically the "Basic Search" or "Advanced Search" option, entering "11864641" into the patent number field.

Based on the information provided in the Google Patents link for US11864641B2, the patent itself lists several prior art documents. To identify the most relevant prior art, it is necessary to examine each cited reference and compare its disclosure to the claims of US11864641.

Here are the prior art references explicitly mentioned and incorporated by reference in US11864641:

1. U.S. application Ser. No. 16/583,168

   • Full Citation: U.S. application Ser. No. 16/583,168, filed Sep. 25, 2019, entitled "INTERPOSABLE MAGNETICALLY COUPLED DEVICES".
   • Publication/Filing Date: September 25, 2019 (filing date).
   • Brief Description: This application generally relates to interposable magnetically coupled devices. As US11864641 is a continuation of this application, its content is directly relevant to the core concepts of magnetically coupled accessories and devices, and the interposition of such devices.
   • Potential Anticipation (35 U.S.C. § 102): Given that US11864641 is a continuation of this application, this reference would be considered prior art only if the claims of US11864641 are not entitled to the priority date of this application. However, as it is a parent application, it is highly likely to disclose many aspects foundational to all claims of US11864641, particularly those related to magnetically coupled devices and stacked configurations (e.g., Independent Claims 1, 10, 15, 19, 22).

2. U.S. Provisional Patent Application No. 62/736,379

   • Full Citation: U.S. Provisional Patent Application No. 62/736,379, filed on Sep. 25, 2018, entitled "INTERPOSABLE MAGNETICALLY COUPLED DEVICES".
   • Publication/Filing Date: September 25, 2018 (filing date).
   • Brief Description: This provisional application shares the same title and filing date as the non-provisional application 16/583,168 (above), indicating it is the foundational disclosure for the concepts of interposable magnetically coupled devices.
   • Potential Anticipation (35 U.S.C. § 102): Similar to the non-provisional parent application, this provisional application is likely to disclose the core concepts of magnetically coupled accessories and devices, including interposition and stacking (e.g., Independent Claims 1, 10, 15, 19, 22). It serves as the priority document for the later-filed applications.

3. U.S. patent application Ser. No. 14/288,243

   • Full Citation: U.S. patent application Ser. No. 14/288,243, filed May 27, 2014, entitled "LOW PROFILE MAGNETIC MOUNT FOR ELECTRONIC DISPLAY DEVICES".
   • Publication/Filing Date: May 27, 2014 (filing date).
   • Brief Description: This application describes low-profile magnetic mounts for electronic display devices. It is directly referenced in US11864641 concerning surface-side attachments affixed to nonmagnetic surfaces and device-side attachments coupled to electronic display devices.
   • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant to the magnetic mounting aspects of US11864641. It likely anticipates or renders obvious elements of claims pertaining to the magnetic coupling of a device to a surface or object, particularly aspects of Independent Claims 1, 19, and 22 that describe device-side attachments and surface-side attachments.

4. U.S. patent application Ser. No. 15/059,163

   • Full Citation: U.S. patent application Ser. No. 15/059,163, filed Mar. 2, 2016, entitled "SELF-ALIGNING, MULTI-SURFACE MAGNETIC MOUNT FOR ELECTRONIC DISPLAY DEVICES".
   • Publication/Filing Date: March 2, 2016 (filing date).
   • Brief Description: This application details self-aligning, multi-surface magnetic mounts for electronic display devices. US11864641 explicitly states that its mounting systems may include a surface-side attachment and device-side attachment as described in this reference. It also mentions that exemplary configurations of magnets for the wallet are disclosed in U.S. Publication No. 2016-0260532, which is likely the publication of this application or a related one.
   • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant for claims involving self-aligning magnetic arrangements and the ability to mount devices on various surfaces. It likely anticipates or renders obvious aspects of Independent Claims 1, 10, 19, and 22, especially regarding the arrangements of magnets of alternating polarity for self-alignment and different orientations.

5. U.S. Pat. No. 10,134,517

   • Full Citation: U.S. Pat. No. 10,134,517, the content of which is incorporated by reference herein.
   • Publication/Filing Date: The Google Patents entry for US11864641 states the filing date for US10134517 is April 28, 2016, and the publication date is November 27, 2018.
   • Brief Description: This patent describes various magnet arrangements which may be utilized within the systems for facilitating the attachment of add-on devices to mobile devices.
   • Potential Anticipation (35 U.S.C. § 102): This patent directly addresses magnet arrangements for attaching add-on devices to mobile devices. Therefore, it is highly likely to anticipate or render obvious elements related to the specific configurations and functionalities of the magnetic arrangements in Independent Claims 1, 10, 15, 19, and 22.

The two U.S. patent applications (Ser. No. 16/583,168 and Ser. No. 62/736,379) are particularly relevant as US11864641 is a continuation application, implying a direct lineage and shared subject matter. The other listed patent applications and issued patent are also highly relevant due to their explicit incorporation by reference and the description of their relevance within the US11864641 patent document itself.
