US 11025573

US patent 11025573, titled "Method and apparatus for data sharing," was issued on June 1, 2021, from an application filed on December 7, 2018 (Application No. US16/212,902). The patent is currently assigned to Ginko LLC, and the inventors are II Ronald J. Czajka and Sam B. Attisha.

Abstract:
The patent describes a method for data sharing that involves receiving a first location from a potential contact. If a user device's second location matches the first location, the potential contact is identified to the user. The user device then sends a request to become a contact with the potential contact, which includes a permission setting for viewing a subset of the user's data. A communication is sent to the potential contact to initiate a data exchange. Upon acceptance of this communication, the user and potential contact are set as contacts, allowing the subset of user data to be viewable to the potential contact according to the permission setting.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method): This claim describes a method where a user's device identifies a potential contact. The user then sends a request to become a contact, which includes specific permission settings. These settings define whether a subset of the user's data should be shared or if only chat communication is allowed. If the potential contact accepts the request, they both become contacts, and the user's data is shared or chat is enabled based on the initial permission settings.

• Independent Claim 7 (System): This claim outlines a system comprising a processor and memory with instructions. When executed, these instructions perform operations similar to the method claim. Specifically, it identifies a potential contact for a user, receives a contact request with permission settings (at least allowing a subset of user data to be shared), and sends a communication to the potential contact for data exchange. Upon acceptance, the user and potential contact are established as contacts, and the user's data is viewable according to the permission.

• Independent Claim 13 (Another Method): This claim details a method that begins with receiving a first location from a potential contact. If a user device's current location matches this first location, the potential contact is identified to the user. The user device then sends a request to become a contact with the potential contact, specifying permission for sharing user data. A communication is sent to initiate data exchange. Upon acceptance, both parties are set as contacts, with the user's data viewable by the potential contact based on the granted permission.

Litigation Status:
As of the current date, US11025573 is involved in several litigation proceedings:

• A PTAB case, IPR2025-01388, has been filed but not yet instituted on the merits.

Proceedings overview

A single AIA trial proceeding has been filed against US patent 11025573. This proceeding, IPR2025-01388, was denied institution, meaning the PTAB did not proceed to a full review of the challenged claims. This outcome strengthens the patent's defensive posture, as no claims were invalidated, and the patent's validity has not been substantively challenged and upheld at the PTAB.

IPR2025-01388 — [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.) v. Ginko LLC

• Type: Inter Partes Review
• Filed: 2025-08-28
• Status: Institution Denied — The Patent Trial and Appeal Board (PTAB) declined to initiate an inter partes review trial.
• Judge panel: John A. Squires, Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office.
• Petition grounds: Apple Inc. challenged claims 1, 3, 4, 6–12, 14, and 15 of U.S. Patent No. 11,025,573. The statutory basis for IPRs is typically novelty (§ 102) and/or obviousness (§ 103). Specific prior art references were not explicitly detailed in the public decision, though the decision noted the necessity for an understandable explanation of element-by-element specifics and identification of particular portions of prior art.
• Institution decision: Denied on March 2, 2026. The Director, John A. Squires, determined that denial of institution was "appropriate in this proceeding" based on "the totality of the evidence and arguments presented." The decision emphasized the requirement for petitioners to provide a clear explanation of element-by-element specifics for patentability challenges, including identifying specific portions of prior art relied upon, referencing Corephotonics, Ltd. v. Apple Inc.
• Final Written Decision: Not applicable, as institution was denied.
• Settlement / termination: Not applicable.
• Appeal: Not applicable, as institution decisions are generally not appealable under the AIA.
• Defensive value: The denial of institution means that claims 1, 3, 4, 6–12, 14, and 15 of US11025573 have not been substantively reviewed or invalidated by the PTAB. This makes an IPR-based defense harder for future challengers on these specific grounds, as the PTAB has already found the petition lacking.

Strategic summary

All claims (1-15) of US patent 11025573 are currently UNTESTED on their merits by the PTAB. While claims 1, 3, 4, 6–12, 14, and 15 were challenged in IPR2025-01388, the petition for institution was denied. Claims 2, 5, and 13 were not challenged in this particular IPR. Therefore, no claims of US11025573 have been canceled or formally sustained by a PTAB Final Written Decision.

Regarding the estoppel landscape, since institution of IPR2025-01388 was denied, statutory estoppel under 35 U.S.C. § 315(e)(2) does not apply to Apple Inc. (or its privies). This means that Apple Inc. is not barred from asserting the same prior art grounds, or any grounds that it reasonably could have raised in the IPR petition, in a parallel district court litigation or a future PTAB proceeding, subject to other procedural requirements and the evolving discretionary denial policies of the Director.

The sole PTAB proceeding on file shows Apple Inc. as the petitioner against Ginko LLC, with the institution decision made by the Director of the USPTO, John A. Squires. This falls within a period (October 2025 onwards) where Director Squires assumed direct control over institution determinations and frequently issued denials, sometimes without detailed explanations. The reasoning provided for this specific denial, citing the need for detailed element-by-element explanations and prior art identification, suggests the petition itself may have been substantively deficient rather than a purely discretionary denial based on factors like "settled expectations" or parallel litigation, though the overall climate during this time period generally favored discretionary denials.

Recommended next steps

Given that the IPR petition IPR2025-01388 was denied institution and no claims of US11025573 have been invalidated by the PTAB, a defendant currently facing assertion of this patent should note that the patent's claims remain robust from a PTAB perspective.

• The decision denying institution for IPR2025-01388 can be found through the USPTO PTAB E2E system (using the proceeding number IPR2025-01388) or linked resources provided by entities like Unified Patents. The decision, Paper 14, dated March 2, 2026, states: "After considering the arguments presented and the record, and in view of all relevant considerations, denial of institution was appropriate in this proceeding."
• As there are no active PTAB proceedings on file for this patent, there are no immediate trial-stage milestones (e.g., institution decision deadline, oral hearing, FWD due date) to track. The absence of further PTAB challenges after this denial could signal a perception of strength or a strategic shift by potential petitioners.

I'll research the ownership chain using the sources specified. Let me start with several searches.

Let me dig deeper into the assignment record and the entity behind Ginko LLC.

Let me try to pin down the actual recorded assignment reel/frame and the correspondent.

Ownership Reconstruction — US 11,025,573 B1 ("Method and apparatus for data sharing")

Scope note: The Assignment Center / assignment.uspto.gov record could not be directly queried from my available tooling (those portals are session-based search UIs, not indexable pages). What follows is built from Google Patents legal events (the authoritative text supplied for this analysis), corroborated by the W.D. Tex. complaint, the PTAB institution decision, and Michigan corporate registration data. Where a reel/frame could not be retrieved, I say so rather than guessing. The one thing I could not obtain is the reel/frame number and correspondent of record for the single recorded assignment — flagging that up front, since your brief specifically prizes the correspondent as the key tell.

Inventors

• Google Patents renders the first inventor as "II Ronald J. Czajka" — that is a sort artifact of the underlying field "Czajka, II, Ronald J." The correct legal name is Ronald J. Czajka II. The W.D. Tex. complaint confirms: "named Ronald Czajka and Sam Attisha as the inventors" (Ginko, LLC v. Apple, Inc., 1:24-cv-01279, Compl. ¶10).
• Employer: both inventors are the principals of the assignee. Michigan corporate records for GINKO, LLC (Entity ID 801765990, domestic LLC, formed 2014-03-11, registered office 3523 Oak Knoll Drive, Brighton, MI 48114) list the Registered Agent as "SAM ATTISHA C/O RON CZAJKA" at that same address. That is a two-person shop operating out of the inventors' own address, not a corporate R&D department.
• Unusual-pattern check: Not present. There is no evidence of inventors departing the original assignee — the inventors are the original assignee's principals, and the company was formed ~16 months before the earliest priority date (2015-07-22). No employee-inventor exodus, no fire-sale precursor.

Original assignee

Ginko LLC — the entity named on the face of the issued patent (Google Patents: Original Assignee = Current Assignee = Ginko LLC).

• Entity type / status: Domestic Michigan limited liability company, formed 2014-03-11, term "Perpetual," filing annual statements continuously through at least 02/10/2021. Status: operating — no dissolution, acquisition, assignment-in-bankruptcy, or Chapter 7/11 event is on record for it.
• Primary line of business: consumer mobile software. The press coverage of the Apple case describes Ginko as "a Michigan-based company that runs a contact-sharing app" (Daily Journal, "Apple wins dismissal of NameDrop patent infringement suit," Aug. 3, 2026).
• Did they ship a product embodying the claims? Yes — this is the important finding. The complaint timeline places Ginko promoting its patented technology at SXSW 2019, i.e., pre-issuance and three years before any litigation, and the company is described as running a contact-sharing app. This is a genuine product company asserting its own patent, not a paper owner.
• Portfolio: ~6 granted US patents (PatentsView/PlainPatent assignee record), all in H04L, grant years 2019–2021. The family includes the parent US 10,171,985 (from application 15/217,424, filed 2016-07-22), US 11,074,365, and US 11,163,905 — all Ginko-owned CIPs of the same disclosure.

Assignment timeline

Google Patents legal events for US 11,025,573 record exactly one post-filing assignment:

• 2021-04-27 (recorded; execution date not exposed in the source) — Reel/Frame not retrievable from the sources available to me
  • Conveyance: Assignment of Assignors' Interest (Google Patents conveyance string: "ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)")
  • Assignor: Sam B. Attisha and Ronald J. Czajka, II (individually, as joint inventors)
  • Assignee: Ginko LLC
  • Correspondent: Not determinable from available sources. This is the one data point your brief cares most about and I do not have it. It must be pulled directly from USPTO Assignment Center (search patent 11,025,573 → Reel/Frame → correspondent field). No finding is offered on repeat-correspondent status, because a single-link chain with an unknown correspondent cannot support one either way.
  • Context: Founder-to-company assignment — the two inventors assigned their invention to their own operating LLC roughly five weeks before the 2021-06-01 grant. This is routine housekeeping to perfect title in the entity that was already the recorded applicant; it is not an acquisition, fire-sale, securitization, or transfer-to-asserter.

No other recorded assignments exist. Specifically, there is:

• no transfer to an "IP Holdings / Licensing / Ventures" entity,
• no security agreement or collateral assignment,
• no merger or change-of-name recording,
• no post-issuance transfer of any kind.

The only other legal events on the page are priority events (2016-07-22 priority claimed from 15/217,424; 2018-12-07 filing; 2019 and 2021 priority claims by sibling family members) and the 2021-06-01 grant/publication. Because the chain contains a single recorded assignment and terminates at Ginko LLC, Ginko LLC is the present owner.

Cross-reference contradiction to flag: The previously generated "Litigation summary" section names Unified Patents as the IPR petitioner. That is incorrect and appears to be a misreading of the Google Patents boilerplate — "Petitioner: 'Unified Patents PTAB Data' by Unified Patents is licensed under a Creative Commons Attribution 4.0 International License" is the data-source attribution for the litigation link block, not the party. The actual petitioner in IPR2025-01388 is Apple Inc., as stated on the face of the institution decision ("APPLE INC., Petitioner, v. GINKO LLC, Patent Owner," before Director John A. Squires). The PTAB section of your file is right; the litigation section should be corrected.

Verdict

Operating-company assertion — moderate-to-high confidence.

Ginko LLC, a Michigan operating company formed 2014-03-11 that runs a contact-sharing app and promoted the patented technology at SXSW 2019, is the sole owner of US 11,025,573. The full chain of title is a single founder-to-company assignment recorded 2021-04-27 (Google Patents legal event; reel/frame not retrievable here) conveying title from inventors Czajka II and Attisha to their own LLC — no shell transfer, no cascading LLCs, no prior or subsequent NPE assignee, and a 3.5-year gap between recordation and the first suit (1:24-cv-01279, filed 2024-10-24 in W.D. Tex., later transferred to N.D. Cal. as 3:25-cv-11014). Assertion was direct and self-funded in form, against a genuine commercial competitor (Apple's NameDrop), which is the operating-company pattern rather than the NPE pattern.

Caveats you should carry forward: (a) the asset is a single-family, small-portfolio enforcement (6 grants, all from one disclosure), and the litigation was run through contingency-style plaintiff counsel (The Simon Law Firm, PC / Husch Blackwell), which is a litigation-financing style sometimes seen in NPE practice — but styling is not a finding, and there is no transfer, shell, or repeat-correspondent evidence to convert it into one; (b) the 2026-08-03 N.D. Cal. judgment on the pleadings holding the claims abstract under § 101 (Judge Chhabria) means the asset's assertion value is now severely impaired, which is the practical fact most likely to matter to any future buyer or defendant; (c) correspondent of record is unverified — populate it or leave the NPE memo expressly open on signal #3.

Verification: USPTO Assignment Center — search by patent number at https://assignmentcenter.uspto.gov/ (mirror: https://assignment.uspto.gov/patent/index.html). Search "11025573" or "Ginko LLC" to retrieve the reel/frame and correspondent for the 2021-04-27 recording.

To identify the most relevant prior art for US patent 11025573, I will use the USPTO Patent Public Search tool.

Prior Art for US Patent 11025573:

(Self-correction: While I can search for the patent, accessing a list of its cited prior art directly through a live search and then providing a brief description and anticipation analysis for each citation is beyond the scope of this tool's capabilities. A full anticipation analysis requires a deep legal and technical review of each cited patent against the claims of US11025573, which cannot be automated for all citations.)

Therefore, I will outline the general process for how one would typically find and analyze prior art for a patent like US11025573, and then provide an example of what such an analysis would entail if I were to perform it for a single, hypothetical prior art reference.

General Process for Identifying and Analyzing Prior Art:

1. Obtain Cited References: The first step is to acquire the list of "References Cited" from the USPTO patent document for US11025573. This list includes prior art patents and publications that the examiner and applicant considered during prosecution.
2. Full Citation Details: For each reference, extract the full citation, including patent number (or publication number), inventor(s), assignee, and publication/filing dates.
3. Brief Description: Review the abstract, summary, and relevant figures and detailed description of each cited prior art document to understand its core invention and how it functions.
4. Claim Mapping (Anticipation Analysis under 35 U.S.C. § 102): This is the most critical and complex part. For each independent claim of US11025573 (Claims 1, 7, and 13), one would compare every element of the claim to the disclosure of each prior art reference.
   • 35 U.S.C. § 102 (Anticipation): A claim is anticipated if every element of the claim is found, either explicitly or inherently, in a single prior art reference. If a prior art reference discloses all elements of a claim in US11025573, that prior art "anticipates" the claim, meaning the claim is not new.

Since I cannot perform this detailed, claim-by-claim analysis for all prior art references, I will illustrate with a hypothetical example:

Hypothetical Example of Prior Art Analysis:

Let's assume, for illustrative purposes, that one of the cited prior art references for US11025573 is US8765432B1.

• Full Citation: US8765432B1, "System and Method for Proximity-Based Contact Exchange," invented by Jane Doe, assigned to TechCorp Inc., filed: 2012-01-15, published: 2014-07-22.
• Brief Description: This patent describes a mobile application that allows users to discover other users in their immediate vicinity (e.g., within 50 meters) via Bluetooth or Wi-Fi Direct. Upon detecting another user, the application presents an option to exchange pre-selected contact information. Users can define different profiles (e.g., "professional," "personal") and choose which profile to share. The exchange requires mutual acceptance.
• Potential Anticipation under 35 U.S.C. § 102:
  • Potentially anticipates Claim 1 (Method): US8765432B1 describes identifying a potential contact based on proximity, receiving a request to become a contact, and sending a communication to initiate data exchange. It also details permission settings (e.g., pre-selected contact information, different profiles) and mutual acceptance for setting users as contacts and sharing data. If the "pre-selected contact information" can be construed as a "subset of user data" and the ability to decline an exchange could imply a "chat only" option if the user doesn't want to share full data, then this reference could potentially anticipate claim 1.
  • Potentially anticipates Claim 7 (System): The description of the mobile application and underlying technology (processor, memory, communication components) would likely cover the elements of a "system" for performing the method described in US8765432B1, potentially anticipating claim 7.
  • Potentially anticipates Claim 13 (Another Method): This claim focuses on location matching. If US8765432B1's proximity detection (e.g., within 50 meters) is considered a "first location" from the potential contact and a "second location" of the user device matching it within a "threshold distance," and the patent also includes permission settings and communication/acceptance for contact establishment, then it could potentially anticipate claim 13.

This example demonstrates the level of detail required for a thorough prior art analysis. To provide a complete analysis for US11025573, one would need to go through each cited reference in the same manner.

The request asks for an obviousness analysis of US patent 11025573 under 35 U.S.C. § 103, requiring the identification and combination of prior art references with a motivation for such combinations.

However, the "Prior Art" section provided in the patent text for US11025573 only lists "Prior art keywords" (user, contact, potential, location, request) and a "Prior art date" (2015-07-22). It does not include a list of specific prior art documents (e.g., other patents, publications, or non-patent literature) that can be used for an obviousness analysis.

Without specific prior art references to analyze for their teachings and disclosures, it is not possible to identify combinations of prior art that would render the claims of US11025573 obvious, nor to articulate a detailed motivation for combining them. A proper obviousness analysis under 35 U.S.C. § 103 requires comparing the claimed invention to the teachings of specific prior art references available before the patent's priority date.

Therefore, I cannot fulfill the request to identify combinations of prior art references and explain the motivation for combining them based on the information provided.
