William Grecia v. T-Mobile
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: William Grecia (Pennsylvania)
- Defendant: T-Mobile USA, Inc. (Delaware/Washington)
- Plaintiff’s Counsel: Wawrzyn & Jarvis LLC
- Case Identification: 1:18-cv-10428, S.D.N.Y., 03/01/2019
- Venue Allegations: Plaintiff alleges venue is proper in the Southern District of New York because T-Mobile conducts continuous and systematic business and maintains corporate offices within the district.
- Core Dispute: Plaintiff alleges that Defendant’s "Galaxy" telephone products, when using the Samsung Pay application to manage gift cards, infringe a patent related to a process for transforming a user's request to access cloud-based data into a secure, device-level authorization object.
- Technical Context: The technology at issue addresses methods for digital rights management (DRM) and providing secure, interoperable access to digital assets, such as the value associated with a gift card account, across multiple devices.
- Key Procedural History: The complaint highlights a significant prior litigation, Grecia v. Mastercard Int'l Inc., in which the same court construed three key terms from a related patent in the same family as the patent-in-suit. Plaintiff is leveraging these prior constructions, which will likely be given significant weight and may streamline the claim construction phase of this case.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,887,308 - “DIGITAL CLOUD ACCESS (PDMAS PART III)” (issued Nov. 11, 2014)
The Invention Explained
- Problem Addressed: The patent’s background section describes the limitations of traditional Digital Rights Management (DRM) systems, which often lock content to specific devices, restrict interoperability, and create a risk that consumers could lose access to purchased media if a company’s servers are discontinued (’308 Patent, col. 2:48-67).
- The Patented Solution: The invention proposes a process to create a more flexible and persistent form of digital access rights ('308 Patent, Abstract). An apparatus (e.g., a smartphone) receives an initial "verification token" (such as a gift card number), authenticates it, and then uses an API to communicate with a "verified web service" to obtain a unique account identifier. This identifier is then used to create a "computer readable authorization object" stored locally on the user's device, which manages access rights without constant reliance on a single, proprietary DRM server ('308 Patent, col. 14:31-15:14).
- Technical Importance: This method sought to provide consumers with greater freedom to use their digital content across different devices and over longer periods, more closely emulating the "fair use" flexibility of physical media ('308 Patent, col. 3:1-7).
Key Claims at a Glance
- The complaint asserts independent Claim 1.
- The essential elements of Claim 1 are:
- (a) Receiving an access request for cloud digital content, where the request includes "verification data" that is recognized as a "verification token."
- (b) Authenticating the verification token using a "verification token database."
- (c) Establishing an API communication between the user's apparatus and a "database apparatus" (which is different from the verification token database) related to a "verified web service."
- (d) Requesting "query data" from the API, where the request is for a "verified web service account identifier."
- (e) Receiving the requested query data (the identifier).
- (f) Creating a "computer readable authorization object" on the device by writing the received data to a data store, which is then used to manage user access permissions.
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are "Galaxy" telephone products sold by T-Mobile that contain a central processing unit (CPU) and the Samsung Pay application program code (Compl. ¶11).
Functionality and Market Context
- The complaint focuses on the functionality of adding a gift card to the Samsung Pay application (Compl. ¶13). It alleges that when a user takes a picture of a gift card, the phone receives the card's Primary Account Number ("PAN") and treats it as a "verification token" (Compl. ¶¶13-14). The phone allegedly then authenticates this PAN with the gift card issuer's database (the "verification token database") and establishes an API communication with a "Samsung Token Requestor" (the "database apparatus") to receive a token representing the user's access rights (Compl. ¶¶15-17, 19). This received token is then stored on the phone as an "authorization object" to facilitate future purchases (Compl. ¶¶20-21). The complaint does not provide specific allegations regarding the products' commercial importance beyond their sale by T-Mobile.
No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
'308 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a) receiving an access request for cloud digital content through an apparatus..., the access request being a write request to a data store..., the access request further comprises verification data... recognized by the apparatus as a verification token... | When a user takes a picture of a Walgreens gift card to add it to Samsung Pay, the phone receives the card's Primary Account Number (PAN), which is recognized as a "verification token." This is alleged to be a write request to the phone's storage. | ¶¶13, 14 | col. 14:34-44 |
| b) authenticating the verification token of (a) using a database recognized by the apparatus of (a) as a verification token database... | The Galaxy phone authenticates the gift card's PAN using the gift card issuer's database, which is alleged to be the "verification token database." | ¶15 | col. 14:45-47 |
| c) establishing an API communication between the apparatus of (a) and a database apparatus, the database apparatus being a different database from the verification token database of (b) wherein the API is related to a verified web service... | The Galaxy phone establishes an API connection with a "Samsung Token Requestor," which is alleged to be the "database apparatus" and a "verified web service" that is different from the gift card issuer's database. | ¶¶16, 17 | col. 14:48-58 |
| d) requesting the query data, from the apparatus of (a), from the API communication data exchange session of (c), wherein the query data request is a request for the at least one verified web service identifier... | The phone, using Samsung Pay's code, requests a token from the Samsung Token Requestor. This token is alleged to be a "verified web service account identifier." | ¶19 | col. 14:63-15:2 |
| e) receiving the query data requested in (d) from the API communication data exchange session of (c)... | The phone receives the requested token from the Samsung Token Requestor. | ¶19 | col. 14:63-15:2 |
| f) creating a computer readable authorization object by writing into the data store of (a)... wherein the created... object is recognized... as user access rights... and is processed... using a cross-referencing action... | The phone writes the received token to its storage, creating an "authorization object." This object is allegedly used in a "cross-referencing action" when the user makes purchases to determine access to the gift card account. | ¶¶20, 21 | col. 15:3-14 |
- Identified Points of Contention:
- Scope Questions: The complaint relies on a prior court order that construed "cloud digital content" broadly as "data capable of being processed by a computer" (Compl. ¶14). A point of contention may be whether a gift card account, as accessed by Samsung Pay, falls within the scope of this term as used in the full context of Claim 1.
- Technical Questions: A key technical question is whether the architecture of the accused system maps to the claim. Specifically, what evidence supports the allegation that the "gift card issuer's database" (the alleged "verification token database") is functionally and technically a "different database" from the "Samsung Token Requestor" (the alleged "database apparatus") as required by Claim 1(c) (Compl. ¶¶15, 17). The relationship and division of functions between these entities will be a critical factual dispute.
V. Key Claim Terms for Construction
While the complaint notes that three terms were previously construed, other terms remain central to the dispute.
The Term: "database apparatus"
- Context and Importance: Claim 1(c) requires the user's device to communicate with a "database apparatus" that is distinct from the "verification token database" of step (b). The plaintiff's infringement theory depends on casting the "Samsung Token Requestor" as this "database apparatus" (Compl. ¶17). The definition of this term is therefore critical to determining if the accused system’s architecture meets the claim limitations.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not provide a formal definition of "database apparatus," potentially allowing for a broad reading that covers any remote system capable of storing data and communicating via an API.
- Evidence for a Narrower Interpretation: The patent's figures and description associate the API communication with a "membership API" and an "APIwebsite.com GUI," which suggests a system that provides user identity and membership services, not just any data store ('308 Patent, Fig. 3, 307; Fig. 4, 407). This context could support a narrower construction requiring more than a simple tokenization server.
The Term: "computer readable authorization object"
- Context and Importance: This is the final product of the claimed method, which the complaint alleges is the token received from the Samsung Token Requestor and stored on the phone (Compl. ¶21). The nature and function of this "object" are core to the invention.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term itself is general and could be argued to encompass any digital token or data entry that a system uses to permit access.
- Evidence for a Narrower Interpretation: Claim 1(f) specifies that the object is created by writing either the "verification data" or the "query data" to the data store, and that it is "processed by the apparatus of (a) using a cross-referencing action during subsequent user access requests" ('308 Patent, col. 15:3-14). This could support a narrower definition requiring a specific data structure and a defined "cross-referencing" function, rather than any generic authentication token.
VI. Other Allegations
The complaint does not contain allegations of indirect or willful infringement.
VII. Analyst’s Conclusion: Key Questions for the Case
- Architectural Mapping: A central evidentiary question will be whether the plaintiff can prove that the multi-party Samsung Pay system—which involves the user's device, the gift card issuer, and the Samsung Token Requestor—maps onto the distinct, sequential two-database architecture ("verification token database" vs. "database apparatus") recited in Claim 1.
- Functional Operation: The case will likely turn on a comparison of technical functions: does the process of tokenizing a gift card's PAN, as allegedly performed by Samsung Pay, operate in the same way as the claimed method of using an API to request and receive a "verified web service account identifier" to create a local "authorization object"?
- Impact of Prior Claim Construction: While a prior court order has defined key terms, a critical question remains: how will those established definitions apply to the specific technology of the accused Samsung Pay system? The interpretation of terms like "cloud digital content" and "verified web service" in this new factual context will be a primary focus of the dispute.
