CellTrust Corp v. ionLake LLC
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: CellTrust Corporation (Delaware)
- Defendant: ionLake, LLC (Minnesota); Derrick Girard (individual)
- Plaintiff’s Counsel: Lathrop GPM LLP
- Case Identification: 0:21-cv-01354, D. Minn., 06/08/2021
- Venue Allegations: Venue is alleged to be proper in the District of Minnesota because Defendant ionLake resides and has a physical place of business in Minnesota, Defendant Derrick Girard resides in the district, and a substantial part of the events giving rise to the claims occurred there.
- Core Dispute: Plaintiff alleges that Defendant’s MyRepChat product, a service for tracking and archiving mobile communications, infringes a patent related to using a virtual phone number to separate and record business communications for regulatory compliance.
- Technical Context: The technology addresses the challenge of monitoring and archiving employee text messages in regulated industries (e.g., finance), particularly in "Bring Your Own Device" (BYOD) environments where personal and business communications coexist on a single device.
- Key Procedural History: Plaintiff alleges it sent a letter to Defendant’s counsel on February 17, 2021, providing notice of the published patent application that would later issue as the patent-in-suit. This event forms the basis for Plaintiff’s claims for pre-issuance damages and willful infringement.

II. Technology and Patent(s)-in-Suit Analysis
- Patent Identification: U.S. Patent No. 10,992,802, “System and Method for Tracking and Archiving Mobile Communications,” issued April 27, 2021.
The Invention Explained
- Problem Addressed: The patent describes the increasing use of SMS for business communication and the resulting challenge for enterprises, particularly in regulated industries like finance, to track, archive, and report these communications for compliance purposes (e.g., FINRA rules) ('802 Patent, col. 2:1-12). This problem is compounded by the "Bring Your Own Device" (BYOD) trend, which makes it difficult to separate private personal messages from archivable business messages on an employee's single device ('802 Patent, col. 2:25-33).
- The Patented Solution: The invention proposes a system where a "virtual phone number" (also called a "long code") is associated with a software application on a subscriber's (e.g., an employee's) mobile device ('802 Patent, Abstract). When a communication is sent to or from this virtual number, it is routed through a central gateway server. This gateway sends the message to its intended recipient while also sending a copy of the communication to an enterprise archiving system, thereby creating a compliant record ('802 Patent, col. 7:6-34; Fig. 1A). This architecture separates business communications (routed via the virtual number) from personal communications (which would use the device's native phone number).
- Technical Importance: The described solution enables organizations to enforce communication compliance policies without prohibiting the use of personal mobile devices for work, accommodating the operational efficiencies of a BYOD model ('802 Patent, col. 2:42-52).
Key Claims at a Glance
- The complaint asserts infringement of claims 1-20 of the '802 Patent (Compl. ¶22). Independent claims 1 (method) and 11 (system) are foundational.
- Independent Claim 1 (Method) Elements:
- A method for tracking electronic communications for compliance with regulations.
- At a computer server, receiving a communication intended for a recipient and originating from a mobile app on a mobile device.
- The mobile app is associated with a virtual number.
- The server is configured to use at least one of an email and an API to send the communication to a storage and reporting system.
- The server is configured to use the virtual number as the originator when transmitting the communication to the recipient.
- Independent Claim 11 (System) Elements:
- A system for tracking electronic communications for compliance with regulations.
- A computer server configured to receive a communication from a mobile app associated with a virtual number.
- The server is configured to use an email and/or API to send the communication to a storage and reporting system.
- The server is configured to use the virtual number as the originator when transmitting the communication.
III. The Accused Instrumentality
- Product Identification: Defendant ionLake's "MyRepChat product and service" (Compl. ¶20).
- Functionality and Market Context:
- The complaint alleges, upon information and belief, that MyRepChat utilizes computer servers to enable employees of regulated organizations (e.g., financial advisors) to track their text message (SMS) communications (Compl. ¶20).
- The service allegedly works by associating a "virtual number" with a mobile app installed on the employee's mobile device. The complaint further alleges that the MyRepChat servers capture these text messages and transmit them to a separate system for storage and compliance reporting, such as for FINRA regulations (Compl. ¶20).
- The complaint positions the accused MyRepChat product as a direct competitor to Plaintiff's own SL2 product, alleging they compete for the same customers in the U.S. market (Compl. ¶27).
IV. Analysis of Infringement Allegations
No probative visual evidence provided in complaint. The complaint states that a claim chart is attached as Exhibit C, but this exhibit was not included in the provided filing. The following analysis is based on the narrative allegations in the complaint.
'802 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| at a computer server, receiving a communication intended for a recipient and originating from the mobile app residing on a mobile device... | ionLake’s MyRepChat product utilizes "computer servers" that enable an employee to track text message communications using a "mobile app on the mobile device of the employee/affiliated person." | ¶20 | col. 43:6-9 |
| wherein the mobile app is associated with a virtual number... | The tracking of text messages is done "using a virtual number associated with a mobile app." | ¶20 | col. 43:9-10 |
| wherein the server is configured to use at least one of an email and an API to send the communication to a system capable of storing... and making... available for reporting... | "MyRepChat computer servers capture the text messages and send them to a system for storing and making the communications available for reporting for compliance with regulations..." | ¶20 | col. 43:11-16 |
| and wherein the server is configured to use the virtual number associated with the mobile app as the originator of the communication for transmitting... to the recipient. | The complaint alleges infringement of the claim but does not explicitly describe this functionality for the accused product in its narrative section. This is likely detailed in the missing Exhibit C. | ¶¶20, 22 | col. 43:17-21 |
- Identified Points of Contention:
- Evidentiary Question: The complaint is a notice pleading and makes its core technical allegations "upon information and belief." A central issue will be what evidence Plaintiff can produce in discovery to demonstrate that the MyRepChat system's actual operation meets every limitation of the asserted claims.
- Technical Question: Claim 1 requires the server to use "at least one of an email and an API" to send the communication to the archiving system. The complaint alleges the MyRepChat servers "send them to a system for storing," but does not specify the mechanism. The case may turn on whether the specific data transfer protocol used by MyRepChat falls within the scope of "email" or "API" as used in the patent.
V. Key Claim Terms for Construction
- The Term: "virtual number"
- Context and Importance: This term is the technological linchpin of the asserted claims. Its definition is critical because infringement hinges on whether the accused MyRepChat system uses a number that qualifies as a "virtual number." Practitioners may focus on this term because its scope will determine whether the patent covers only the specific "long code" implementations discussed in the specification or a broader class of non-native identifiers.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification suggests the term's essence is its separation from the device's carrier-assigned number, stating, "Instead of using the true phone number assigned by the carrier to the SIM card of the employee's mobile device, the long code 302 is published as the employee's phone number" ('802 Patent, col. 6:26-29). This could support an interpretation covering any secondary number routed through a gateway for tracking.
- Evidence for a Narrower Interpretation: The patent frequently uses "long code" as a synonym and spends considerable text distinguishing these numbers from "short codes" based on length and regulatory use ('802 Patent, col. 6:34-61). A party might argue this context narrows the term to 10-digit, SMS-chat-capable numbers and excludes other types of identifiers.
VI. Other Allegations
- Indirect Infringement: The complaint alleges infringement against Derrick Girard individually for induced infringement under 35 U.S.C. § 271(b) (Compl. ¶29). The alleged factual basis is that Girard, as CEO, "personally taken part in promoting, marketing, offering for sale, and selling the MyRepChat product" and has "directed ionLake and its employees and contractors to make, use, offer for sale, and/or sell" the accused service (Compl. ¶¶30-31).
- Willful Infringement: The complaint alleges willful infringement against both ionLake and Derrick Girard (Compl. ¶¶25, 33). The allegations are based on knowledge of the patent "as of April 27, 2021" (its issue date) and continued infringement thereafter (Compl. ¶24). This knowledge is allegedly supported by a notice letter sent by Plaintiff's counsel on February 17, 2021, which identified the published application that matured into the '802 Patent (Compl. ¶15). Plaintiff also alleges pre-issuance damages based on this notice (Compl. ¶21).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of evidentiary proof: Can CellTrust, through discovery, uncover technical evidence demonstrating that the MyRepChat system architecture, particularly its method of transmitting data to the storage system and its handling of originator information, performs the specific functions required by each element of the asserted claims?
- A second key question will be one of objective recklessness: Given the plaintiff's alleged pre-issuance notice letter, the willfulness inquiry will focus on whether ionLake's decision to continue its commercial activity after the '802 patent issued constituted conduct that was objectively reckless of a high likelihood of infringement, or if it had a reasonable, good-faith basis for believing it did not infringe or that the patent was invalid.
- A final question concerns personal liability: The case against the individual defendant, Derrick Girard, will depend on whether his specific, personal actions rise to the level of actively inducing infringement by the corporate entity, ionLake, a standard that requires more than just holding a corporate office.
