II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,054,860 - "Digital Verified Identification System and Method"
The Invention Explained
- Problem Addressed: The patent addresses the difficulty in verifying the identity of a signatory to an electronic document. It notes that common methods for electronic signatures are "rather difficult to authenticate," creating a need for a more robust system to associate an electronic file with a specific entity (’860 Patent, col. 1:12-40).
- The Patented Solution: The invention is a system for creating a "digital identification module" that can be embedded into an electronic file, such as a word processing document (’860 Patent, Abstract; col. 2:15-24). A "module generating assembly" receives "verification data" from an entity (e.g., username, personal information) and uses it to create the module. This module contains a visible "primary component" (like a digital signature image) and hidden "metadata components" (e.g., date, time, location, MAC address) that can be revealed by hovering a mouse over or clicking on the primary component (’860 Patent, col. 2:25-47, Fig. 6).
- Technical Importance: The technology aimed to provide a method for embedding verifiable identity information and document provenance directly into an electronic file, moving beyond simple textual representations of signatures (’860 Patent, col. 1:37-52).
Key Claims at a Glance

III. The Accused Instrumentality
Product Identification
The accused instrumentalities are Defendant's point-of-sale terminals, specifically the Clover Mini, Clover Mobile, and Clover Station (Compl. ¶9).
Functionality and Market Context
The complaint alleges these products perform the function of "electronically signing and authenticating an electronic document by a verified signatory" (Compl. ¶9). The allegations focus on the systems' processing of EMV chip card data and electronic signatures from cardholders to authenticate a transaction, which generates an electronic document or record (Compl. ¶15, ¶18).
IV. Analysis of Infringement Allegations
The complaint provides a high-level, narrative mapping of the accused products to the claims rather than a detailed, element-by-element chart. No probative visual evidence provided in complaint.

Identified Points of Contention:
- Scope Questions: A central question is whether the patent's term "electronic file," which the specification exemplifies as a "word processing document" (’860 Patent, col. 2:19-20), can be construed to read on the electronic transaction records allegedly generated by the accused POS systems.
- Technical Questions: The complaint alleges that the handling of EMV data constitutes "creating" a "digital identification module." A key factual dispute may arise over whether this data processing is equivalent to the patent's description of generating a distinct file or object (e.g., a JPEG) and embedding it into a separate document.
- Scope Questions: The infringement theory for the "embedded within only a single electronic file" limitation rests on the allegation that each transaction file receives a unique code (Compl. ¶15, ¶18). This raises the question of whether this functional uniqueness satisfies the claim's structural requirement, particularly when the specification describes this limitation in terms of a module that can be rendered "inoperable" or "automatically deleted" after a pre-selected number of uses (’860 Patent, col. 4:26-36).
V. Key Claim Terms for Construction
The Term: "digital identification module"
- Context and Importance: This term is the core of the invention. The viability of the infringement case depends on whether the "data structures associated with an EMV chip card" (Compl. ¶15) can be properly characterized as a "digital identification module." Practitioners may focus on this term because the accused functionality appears to be data processing, whereas the patent's embodiments describe a discrete object.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification states the module "may include virtually any file, item, object, or device structured to be embedded or otherwise disposed within an electronic file" (’860 Patent, col. 3:32-35).
- Evidence for a Narrower Interpretation: The specification repeatedly provides examples of the module as an "image or photographic file," such as a "JPEG," "PNG," or "GIF" file, or a "signature file" that is imported into a separate program like a word processor (’860 Patent, col. 3:36-40; col. 5:15-20).
The Term: "cooperatively structured to be embedded within only a single electronic file"
- Context and Importance: This limitation defines a key structural feature of the claimed module. Infringement hinges on whether the accused functionality meets this specific constraint. The complaint’s theory—that a unique code per transaction satisfies this—suggests this term will be a focal point of dispute.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The language could be interpreted functionally to mean that the module is intended for use with, and is uniquely associated with, only one file or transaction, which aligns with the complaint's allegations.
- Evidence for a Narrower Interpretation: The specification describes a more technical structure where a user can pre-select the number of documents a module can be embedded in, after which the module "may be automatically deleted, become inoperable, or otherwise be disposed in an inactive state" (’860 Patent, col. 4:26-36). This suggests a technical enforcement mechanism, not just a one-to-one association.
VI. Other Allegations
- Indirect Infringement: The complaint does not provide specific factual allegations to support a claim for indirect infringement, such as knowledge or intent to induce.
- Willful Infringement: The complaint does not contain allegations of pre- or post-suit knowledge of the patent by the Defendant to support a claim for willful infringement.
VII. Analyst’s Conclusion: Key Questions for the Case
Given the cancellation of most asserted claims, the dispute is now narrowly focused. The case will likely turn on the following core questions:
- A core issue will be one of definitional scope: can the patent’s concept of a "digital identification module" embedded in an "electronic file"—contemplated in the specification primarily as a document like a Word file—be construed to cover the transactional data, including EMV codes, generated and processed by the accused point-of-sale system?
- A key evidentiary question will be one of technical operation: does the accused system's process for handling transaction data meet the specific structural limitation that the "module" is "cooperatively structured to be embedded within only a single electronic file," or is there a fundamental mismatch between the accused system’s data flow and the one-use, self-inactivating module described in the patent's embodiments?
