CellTrust v. ionLake: Jury Finds No Infringement, Both SMS Patents Invalid
CellTrust Corporation brought a patent infringement action in the District of Minnesota against ionLake, LLC and the Girard brothers over two patents covering SMS tracking and mobile communications archiving. After 1,286 days of litigation, a jury returned a verdict finding no infringement and invalidating both asserted patents — delivering a complete defense win.
SMS Patent Invalidity: How ionLake Defeated Both CellTrust Claims at Trial
CellTrust Corporation filed this patent infringement action in the District of Minnesota on 7 November 2019 against ionLake, LLC, Wade Girard, and Derrick Girard. The suit asserted two patents — US9775012B2 and US10778837B2 — covering systems and methods for tracking SMS messages and archiving mobile communications. CellTrust alleged that ionLake's products and services infringed both patents.
The case proceeded through over 3.5 years of litigation before reaching a jury verdict. The jury found that defendants did not infringe either asserted patent and further found that both patents are not valid. The Minnesota District Court entered judgment in favor of all defendants — ionLake, LLC, Wade Girard, and Derrick Girard — based on that verdict. The Basis of Termination is recorded as Judgment on the merits for Defendant.
A dual finding of non-infringement and invalidity represents a complete outcome for the defendants, eliminating any residual exposure from the asserted patents. The specific grounds for invalidity found by the jury — whether anticipation, obviousness, or otherwise — are not detailed in the available public record. What the resolution signals for CellTrust's broader patent enforcement strategy in the mobile communications compliance space remains to be seen.

US9775012B2 & US10778837B2 — SMS tracking and mobile communications archiving
Any company building or deploying SMS tracking, mobile message archiving, or communications compliance platforms should be aware of this case's outcome. Both patents have been found invalid by a jury, materially reducing — but not necessarily eliminating — their practical enforcement risk. Related continuation applications or family members of these patents could carry overlapping claim language and may not yet have been challenged. Product teams in enterprise mobile compliance, RegTech, and financial services communications archiving should conduct a targeted FTO review.
Official order — verbatim text
The court's order expressly adjudges non-infringement and invalidity on both US9775012B2 and US10778837B2 and enters judgment for all three defendants. The phrasing — 'cannot be liable on any of CellTrust Corporation's claims' and 'may not pursue patent infringement claims based on those patents' — reflects a jury verdict that resolved every substantive issue against the plaintiff. The invalidity finding is particularly consequential: it voids the patents as enforceable assets beyond this litigation, not merely as against these defendants.
Defendant verdict: what the jury's dual finding means for both parties
Jury verdict: non-infringement and invalidity
A jury in the District of Minnesota returned a verdict on two independent grounds: first, that defendants did not infringe the asserted patents; second, that both patents are not valid. The court entered judgment for defendants on both findings. A dual verdict of this kind is the most complete possible defense outcome — it eliminates present infringement liability and extinguishes the patents as future enforcement tools.
Complete defense verdictCellTrust loses enforcement rights on both patents
The invalidity finding means CellTrust may not pursue infringement claims based on US9775012B2 or US10778837B2. Beyond losing this action, the patents themselves are legally undermined as enforcement assets. CellTrust's ability to assert these patents against other parties in future proceedings is materially compromised by the jury's invalidity conclusion, though the specific invalidity grounds are not disclosed in the available record.
Patents invalidatedionLake and the Girards cleared on all claims
ionLake, LLC, Wade Girard, and Derrick Girard secured judgment in their favor on every claim CellTrust advanced. The non-infringement finding independently ends all liability; the invalidity finding provides additional protection against any revival of these claims. Defendants may continue operating their SMS tracking and archiving products without restraint from these two patents. Whether any fee or cost award follows is not stated in the available public record.
Full defense winInvalidity ruling weakens patent barriers in mobile compliance archiving
The invalidation of both asserted patents removes two potential legal barriers from the mobile communications tracking and archiving sector. Competitors and new entrants in SMS compliance, enterprise mobile archiving, and related RegTech markets can treat these patents as neutralised. Companies holding similar portfolio assets in this space should monitor whether the invalidity rationale — once disclosed in full court records — affects the validity posture of related patents.

R&D signals in the mobile communications compliance patent space
Forward-looking patent and innovation intelligence derived from CellTrust v. ionLake — covering SMS archiving, mobile compliance technology, and enterprise communications IP trends.
CellTrust's patent family beyond the two invalidated assets
With US9775012B2 and US10778837B2 invalidated at trial, the strategic relevance of CellTrust's broader patent estate — including any continuation, divisional, or continuation-in-part applications — warrants monitoring. Portfolio activity in the mobile communications compliance space may signal whether CellTrust is rebuilding enforcement leverage through new filings or narrowing claim strategies.
Portfolio watchFiling trends in enterprise SMS archiving and mobile compliance
The enterprise mobile archiving and SMS compliance market has attracted filing activity from telecommunications vendors, financial compliance SaaS firms, and cybersecurity companies. Understanding the density and recency of patent activity in claim areas covering message interception, retention workflows, and audit trail generation helps R&D teams identify white space and freedom-to-operate zones in this sector.
Landscape analysisionLake's patent position in mobile compliance technology
ionLake successfully defended against two SMS tracking patents at trial. Understanding whether ionLake holds its own patent assets in mobile communications archiving — or operates purely as a trade-secret and product-based competitor — is relevant for companies assessing the competitive IP landscape in enterprise compliance technology. A portfolio search surfaces any defensive or offensive IP filing activity.

What this case signals for the mobile communications compliance IP landscape
A complete trial loss — non-infringement plus invalidity — carries significant implications for patent enforcement strategy in SMS tracking and mobile archiving technology.
Dual jury findings of non-infringement and invalidity are rare and decisive
When a jury finds both non-infringement and invalidity, the patent holder faces maximum litigation exposure: the claims fail on the facts and the patent itself is struck down. Companies asserting mobile communications patents should assess claim scope carefully before proceeding to trial — juries in technically complex cases can and do find invalidity independently of infringement.
SMS archiving and compliance patent assertions face heightened prior art risk
The SMS tracking and mobile archiving space has deep commercial prior art dating back to early enterprise messaging platforms. This case suggests that patent claims in this domain may be vulnerable to invalidity challenges if claim scope overlaps with established compliance or messaging infrastructure. R&D teams building in this space should document design-arounds and prior art proactively.
CellTrust v ionLake — key questions answered
The jury returned a verdict finding that ionLake, LLC, Wade Girard, and Derrick Girard did not infringe patents US9775012B2 or US10778837B2, and that both patents are not valid. The Minnesota District Court entered judgment in favor of all defendants. The case is recorded as Judgment on the merits for Defendant and was closed on 16 May 2023.
CellTrust asserted US9775012B2 (application US14/890192) and US10778837B2 (application US16/536517). The patents cover systems and methods for tracking SMS messages and for tracking and archiving mobile communications — technology relevant to enterprise compliance and regulated-industry electronic communications retention requirements.
The jury's invalidity finding means that US9775012B2 and US10778837B2 are not valid patents, and as the court's order states, CellTrust may not pursue patent infringement claims based on those patents. The specific grounds of invalidity — such as anticipation or obviousness — are not detailed in the available public record. Related continuation or family applications may not be affected by this finding.
The case was filed on 7 November 2019 and closed on 16 May 2023 — a duration of 1,286 days, or approximately 3.5 years. This is a lengthy first-instance patent trial, consistent with complex multi-patent infringement actions that proceed through full fact discovery, claim construction, and a jury trial in the District of Minnesota.
Wade Girard and Derrick Girard were named as individual defendants alongside ionLake, LLC. The jury's verdict of non-infringement covered all defendants, including the Girards personally, and judgment was entered in their favor. The basis for naming them individually — such as allegations of personal participation in infringement — is not further detailed in the available public record.
