This Texas trade secret verdict is a good reminder that even when a plaintiff wins big, trade secret litigation can still turn on procedural issues at the very end.
HouseCanary just secured a $175 million compensatory trade secret verdict against Amrock in Bexar County after nearly a decade of litigation. For a brief moment, the jury also awarded another $201.6 million in punitive damages. The judge quickly erased it from the verdict form after finding the jury was not unanimous on that question.
Even with the punitive award gone, HouseCanary is still expected to recover around $260 million in compensatory damages once prejudgment interest is included. That is a huge result by any standard. It is also another example of how trade secret cases can produce very large numbers while still remaining highly vulnerable on appeal.
Why this HouseCanary verdict matters
The basic allegation was that Amrock misappropriated trade secrets tied to HouseCanary’s home valuation technology and related data. After almost four weeks of testimony, the jury only needed about three hours to reach a verdict in HouseCanary’s favor.
That speed is meaningful. When juries move that quickly in a complex trade secret case, it usually means one side told a much clearer story about ownership, misuse, and harm. Here, HouseCanary appears to have persuaded the jury that its models and data were not just useful business information, but protectable trade secrets that had real commercial value.
The damages number is also telling. Trade secret cases often get talked about as if they are hard to value or inherently speculative. This verdict is a reminder that when a plaintiff can tie confidential technology to a concrete business impact, juries are willing to put very serious money on the board.
How the case got back to trial
This was not the first major verdict in the dispute.
The fight goes back to contracts signed in 2013. In 2018, HouseCanary won an even larger trade secret verdict, reportedly around $706 million. But that result did not survive appellate review. The Fourth Court of Appeals reversed after finding problems with the jury charge and the way liability theories had been presented.
That history is important because it shows how trade secret litigation is not just about whether something was taken. It is also about whether the case is framed correctly, whether the jury instructions match the law, and whether the plaintiff cleanly separates its legal theories.
In other words, a company can have a compelling story, substantial damages, and still lose ground if the case is not structured properly for trial and appeal.
That is one of the hardest lessons in trade secret litigation. Winning the facts is not always enough. Not only do you need good substance, but you also need solid procedure.
The $201.6 million mistake
The most dramatic moment in this trial may have come after the verdict was already on paper.
Jurors initially checked the boxes awarding $201.6 million in punitive damages. But under Texas law, exemplary damages require a unanimous jury. When the judge polled the panel, she discovered that one juror did not agree. The judge literally erased the punitive damages from the verdict form.
That is a remarkable courtroom moment, but it is also a useful legal reminder.
Punitive damages in trade secret cases are never automatic. Even when a jury is clearly upset with the defendant, the path to exemplary damages can be narrow and highly technical. If the statutory requirements are not met exactly, the number can disappear just as quickly as it appeared.
So yes, the headline number changed quickly. The more important takeaway is that procedure still matters, even after a plaintiff has clearly won the room on substance.
What comes next?
Amrock has already said, not surprisingly, that it plans to challenge the verdict aggressively. Given the history of this case, another appeal feels almost inevitable.
The likely battles are familiar ones. What exactly qualified as a trade secret here? Were the jury instructions procedurally clean this time? Was the damages model properly tied to the claimed misappropriation? Those questions have already shaped this case once, and they will likely shape it again.
That does not take away from HouseCanary’s result. A $175 million compensatory verdict, with a likely total recovery around $260 million after interest, is still an enormous win after ten years of litigation. But it does mean the case is not over just because the jury has spoken.
Trade secret plaintiffs should remember that a trial verdict is a milestone, not always the finish line.
What companies should take from this trade secret verdict
First, if your company is building valuable models, data sets, algorithms, or other internal decision tools, do not assume their value speaks for itself. If you want to enforce trade secret rights later, you need to define what is confidential, document who had access, and show how the information created business value.
Second, damages matter, but they need structure. Large verdicts do not come from vague claims that something important was used. They come from disciplined storytelling around ownership, secrecy, misuse, and economic harm.
Third, litigation readiness is not just about having a good claim. It is about being ready for the long haul. This case has been going on for about ten years. That is a serious reminder that trade secret disputes can become endurance contests, especially when the damages are large and the technology is complex.
Finally, this case shows why procedural discipline matters so much. Jury instructions, verdict forms, unanimity rules, and damages theories may sound technical, but they can determine whether a win holds up or falls apart.
Everyone talks about the substantive merits of a case, but procedure can turn a win into a loss.
If your company is relying on proprietary technology, data, models, or internal know-how to compete, now is a good time to ask yourself a simple question: if someone took this, could clearly explain what was stolen, why it is secret, and what it is worth?
