In CellTrust v. ionLake, Judge Wright denied CellTrust’s posttrial motions and denied Defendants’ request for patent-litigation attorneys’ fees.
CellTrust’s patent infringement claims and Defendants’ request for attorneys’ fees were affected. The jury’s findings of no infringement and patent invalidity remained in place, and no party received attorneys’ fees under 35 U.S.C. § 285.
What happened
In CellTrust Corporation v. ionLake, LLC, a jury found that ionLake and the Girards did not infringe CellTrust’s patents and that the asserted patent claims were invalid as obvious. CellTrust asked the court to overturn that verdict, order a new trial, or change the judgment.
The court denied CellTrust’s motion for judgment as a matter of law, motion for a new trial, and motion to alter or amend the judgment. The court concluded that substantial evidence supported the jury’s findings on both noninfringement and invalidity, and that the alleged trial errors did not justify disturbing the verdict.
Judge Wilhelmina M. Wright also denied Defendants’ motion for attorneys’ fees. She concluded that the case was not exceptional because CellTrust litigated reasonably and in good faith, and Defendants had not shown abusive litigation conduct or frivolous claims.

Background
CellTrust alleged that ionLake’s MyRepChat service infringed claims in two CellTrust patents concerning systems for tracking text messages and meeting audit requirements. CellTrust also asserted infringement-related claims against Derrick Girard and Wade Girard. ionLake and Derrick Girard sought declarations that the patents were not infringed and were invalid.
After a jury trial, judgment was entered for Defendants on May 16, 2023. The jury found no infringement and found that the asserted patent claims were invalid. CellTrust then moved for judgment as a matter of law, a new trial, and alteration or amendment of the judgment. Defendants moved for attorneys’ fees under 35 U.S.C. § 285.
Judgment as a Matter of Law
The court denied CellTrust’s motion concerning infringement. The court concluded that the asserted claims required direct sending from the MyRepChat server or gateway to an electronic discovery system or related system. The court determined that its earlier statement during trial was not a definitive claim-construction ruling. CellTrust’s technical expert had not analyzed the accused servers or customer configurations to establish direct sending, and questions also remained about whether CellTrust proved the intent required for induced infringement. The court held that substantial evidence supported the jury’s finding of noninfringement.
The court also denied CellTrust’s motion seeking judgment that the asserted claims were valid. It concluded that Defendants presented sufficient evidence to support the jury’s finding that the claims would have been obvious. The court found adequate circumstantial corroboration for the testimony of Defendants’ expert, Mr. Antonov; concluded that the obviousness inquiry could consider the relevant prior art as a whole; and found that Mr. Antonov adequately addressed the claims even without expressly discussing every limitation word-for-word. The court also found that CellTrust did not provide sufficient evidence connecting alleged secondary considerations, such as industry praise, to the claimed inventions.
Motion for a New Trial
The court denied CellTrust’s motion for a new trial. It found that some of Defendants’ trial statements were arguably improper, but CellTrust had not preserved objections to all of them and had not shown that the statements affected the verdict or caused a miscarriage of justice.
The court agreed that Defendants’ argument about a specific 75-percent customer statistic was a previously undisclosed noninfringement theory that reasonably surprised CellTrust. But the court found that the surprise was not incurable and that CellTrust had not shown a reasonable probability that the argument changed the result. The court also rejected CellTrust’s challenges to the jury instructions, evidentiary rulings, and earlier claim-construction decisions, finding no prejudicial legal error or abuse of discretion. The jury’s verdict therefore stood.
Motion to Alter or Amend the Judgment
The court denied CellTrust’s motion to alter or amend the judgment under Rule 59(e). The court found that CellTrust had not shown an exceptional circumstance, a serious legal or factual error, newly discovered evidence, or a miscarriage of justice. The court concluded that CellTrust was primarily seeking to relitigate issues that the jury had reasonably resolved against it.
Attorneys’ Fees
The court denied Defendants’ motion for attorneys’ fees under 35 U.S.C. § 285. Patent fees may be awarded in an “exceptional” case that stands out because of unreasonable litigation conduct or unusually baseless claims. The court found that CellTrust’s document production, redactions, discovery responses, damages position, and claims against Wade Girard did not establish misconduct or bad faith. It also found that the losing verdict did not by itself show that CellTrust’s infringement or validity positions were exceptionally weak.
Considering the circumstances as a whole, the court emphasized that CellTrust litigated reasonably and in good faith, Defendants had not raised their alleged deficiencies before trial, and the record did not show abusive conduct or foundationless expert opinions. The court concluded that the high standard for an exceptional case was not met.
Disposition
The court denied all three motions: CellTrust’s motion for judgment as a matter of law; CellTrust’s motion for a new trial and to alter or amend the judgment; and Defendants’ motion for attorneys’ fees.
