Federal Circuit trade secret rulings do not usually read like tire-shop drama, but Coda Development v. Goodyear managed to bring patents, self-inflating tires, a $64 million jury verdict, and a post-trial legal blowout into one unusually instructive package. In December 2025, the U.S. Court of Appeals for the Federal Circuit affirmed judgment as a matter of law, or JMOL, for Goodyear in a misappropriation dispute involving self-inflating tire technology. The headline lesson is simple enough to fit on a sticky note: a trade secret must be specific, actually secret, and actually used. The hard part, as this case shows, is proving all three after years of litigation.
The decision matters far beyond tires. For inventors, startups, manufacturers, engineers, and corporate counsel, it is a cautionary story about how a trade secret claim can look strong in front of a jury yet fail under Rule 50 when the court asks whether the evidence legally supports the verdict. In other words, a big jury award is exciting, but it is not magic. Courts still check the wiring.
What Happened in Coda v. Goodyear?
Coda Development s.r.o., Coda Innovations s.r.o., and inventor Frantisek Hrabal sued Goodyear Tire & Rubber Company and Robert Benedict in the Northern District of Ohio. Coda claimed that Goodyear misappropriated trade secrets involving self-inflating tire, or SIT, technology. The basic allegation was that Coda shared confidential technology with Goodyear during collaboration discussions and that Goodyear later used that information in its own development work and patent activity.
A jury originally sided with Coda on five alleged trade secrets. The award was eye-catching: approximately $2.8 million in compensatory damages and $61.2 million in punitive damages. That is the kind of number that makes boardrooms go quiet and litigation teams refresh the docket like it is a playoff score.
But after trial, Goodyear moved for judgment as a matter of law under Federal Rule of Civil Procedure 50(b). The district court granted the motion, set aside the verdict, and entered judgment for Goodyear on the trade secret claims. Coda appealed. The Federal Circuit affirmed, concluding that no reasonable jury could find trade secret misappropriation based on the evidence and the way Coda defined the alleged secrets.
What Is JMOL, and Why Does It Matter?
JMOL stands for judgment as a matter of law. In federal civil trials, Rule 50 allows a court to take a claim away from the jury, or set aside a verdict after trial, when a party has been fully heard and no reasonable jury would have a legally sufficient evidentiary basis to rule for that party on a necessary issue.
That sounds technical because it is. But the concept is straightforward: juries decide facts, yet verdicts must still be supported by legally adequate evidence. If a plaintiff must prove A, B, and C, and the evidence only supports A and half of B, the court may not let the verdict stand just because the jury liked the story. Litigation is not a vibes-based operating system.
In this case, the Federal Circuit applied the regional circuit’s Rule 50 standard and reviewed the district court’s ruling de novo. The court did not merely ask whether Coda had a compelling narrative. It asked whether the evidence could support each required element of trade secret misappropriation.
The Five Alleged Trade Secrets at Issue
The appeal centered on five alleged trade secrets: TS 7, TS 11, TS 20, TS 23, and TS 24. Each related to self-inflating tire technology, but the Federal Circuit treated them differently depending on the problem with proof.
| Alleged Trade Secret | General Subject | Federal Circuit Problem |
|---|---|---|
| TS 24 | Optimal pump placement in the tire sidewall | Public disclosure and insufficient specificity |
| TS 7 | Multi-purpose interface for transporting air | Functional description without protectable know-how |
| TS 11 | Pump and groove solutions | Undifferentiated list of components |
| TS 20 | Circulating and non-circulating pump variations | Vague component grouping and lack of use evidence |
| TS 23 | Pressure testing results | Insufficient evidence that Goodyear used the full alleged secret |
Why the Federal Circuit Affirmed JMOL on Misappropriation
1. A Trade Secret Must Be Defined with Particularity
The biggest message from the decision is that a plaintiff cannot claim “our secret is the general know-how behind this cool technology” and expect the court to fill in the blanks. Trade secret law protects information, not fog. The plaintiff must identify the information with enough particularity for the court to determine whether it is secret, whether it has independent economic value from secrecy, and whether the defendant misappropriated it.
That requirement is especially important in technical cases. A complex system may contain many public parts, common engineering principles, experimental results, confidential refinements, and business preferences. Calling the whole bundle a trade secret is tempting, but courts want to know exactly what the secret is. Is it a formula? A tolerance range? A manufacturing sequence? A prototype dimension? A test result? A failure mode discovered through expensive experimentation? The answer matters.
For TS 7, TS 11, and TS 20, the court found that Coda’s descriptions were too broad. They described functions, components, or desired outcomes, but they did not isolate the underlying design and development knowledge that supposedly deserved trade secret protection. A list of things a device can do is not the same as a protectable explanation of how to do them.
2. Public Disclosures Can Deflate Trade Secret Claims
TS 24 concerned Coda’s alleged knowledge about the optimal placement of a pump in the tire sidewall, close to and above the rim, where the tire deforms during use. The problem was that Coda had already disclosed related information in public materials, including a patent application and an industry article. Once information becomes public, it usually cannot remain a trade secret. Trade secret law is not a time machine; it cannot pull public knowledge back behind a curtain.
Coda attempted to narrow the secret by arguing that the public disclosures did not capture the same precise concept, such as placement in a conventional or standard tire sidewall. The Federal Circuit was not persuaded because those narrowing terms were not included in Coda’s earlier closed identification of its trade secrets. The court viewed the later refinement as an effort to add specificity after the fact.
This is a crucial lesson for businesses that use both patents and trade secrets. Patent filings publish technical information. Trade secrets require secrecy. Both can be powerful, but they must be coordinated. Otherwise, the company may accidentally publish the very information it later wants to label confidential. That is like locking the front door after mailing everyone a house key.
3. “Use” Requires Evidence, Not Just Suspicion
Trade secret misappropriation is not proven merely by showing that one company learned something and later worked in a similar area. The plaintiff must connect the alleged secret to the defendant’s acquisition, disclosure, or use. Timing can help, similarity can help, access can help, but none of those substitutes for proof of the specific protected information being used.
TS 23 involved tire pump test results showing pressure performance. Coda pointed to a 2009 email and argued that Goodyear relied on Coda’s testing data. The Federal Circuit found the evidence insufficient because the email did not contain the complete set of results described in TS 23, and the testimony did not show that all of those results were disclosed to or used by Goodyear.
That distinction matters. If a trade secret is defined as a full set of testing data, evidence that the defendant saw one related number may not prove use of the whole secret. Courts want the chain: what exactly was disclosed, when, to whom, under what confidentiality obligation, where it appears in the defendant’s work, and why that appearance reflects use rather than public knowledge, independent development, or coincidence.
The Inventorship Claim Also Failed
Coda also pursued a correction of inventorship claim involving Goodyear’s U.S. Patent No. 8,042,586. The theory was tied to the alleged misappropriation: if Goodyear used Coda’s secret contribution in the patented invention, Coda’s founder should be added as an inventor.
The Federal Circuit rejected that claim as well. Once the trade secret theory failed, the inventorship argument lost its main foundation. The court also agreed that the alleged trade secret and the patent claims did not cover the same subject matter in the way required for correction of inventorship. Inventorship is not awarded for being near the invention, inspiring discussion, or contributing general background ideas. It requires contribution to the conception of the claimed invention.
Why This Decision Is Important for Trade Secret Litigation
The ruling is important because it shows how trade secret cases can collapse at the proof stage even after a favorable jury verdict. Many trade secret disputes begin with emotionally powerful facts: a meeting under an NDA, a failed collaboration, a later product, a patent filing, and a sense that someone walked away with the crown jewels. But courts do not protect feelings of betrayal. They protect specifically identified, legally qualifying secrets.
The decision also reinforces a practical defense strategy. Defendants in trade secret cases often push early for a precise trade secret disclosure. They want the plaintiff locked into a closed list before discovery expands into a fishing expedition. Coda v. Goodyear demonstrates why that tactic matters. If the plaintiff later tries to reshape the secret to avoid public disclosure or indefiniteness problems, the court may say, in effect, “Nope, you had your chance.”
Lessons for Plaintiffs: Build the Trade Secret Before the Lawsuit
Identify the Secret Like an Engineer, Not a Marketer
A marketing phrase such as “advanced self-inflating tire architecture” may sound impressive, but it is not enough. A strong trade secret description should identify the concrete information being protected. For example, a plaintiff might specify a particular geometry, pressure threshold, manufacturing sequence, material composition, calibration method, source code routine, or validated test dataset. The more technical the case, the more precision the court will expect.
Separate Secret Know-How from Public Knowledge
Before filing a claim, plaintiffs should conduct a publication audit. Patent applications, conference slides, white papers, customer presentations, press releases, standards documents, and academic articles can all create public disclosure problems. If the alleged secret overlaps with public materials, the plaintiff must explain what remains secret and why that remaining slice has independent value.
Document Disclosure and Use
A good NDA is helpful, but it is not a substitute for proof. Companies should record what was disclosed in confidential meetings, label materials appropriately, track recipients, preserve versions, and maintain internal records showing how the information was developed. If litigation comes later, these records can make the difference between “we think they used our idea” and “here is the exact confidential information, here is when they received it, and here is how it appears in their product.”
Lessons for Defendants: Challenge the Shape of the Secret
For defendants, the case is a reminder that the first battle may be over definition, not damages. If the alleged secret is vague, shifting, or described as a broad category, defendants should press for particularity early. A defendant cannot fairly defend against a moving target. Courts are increasingly sensitive to that problem, especially where the plaintiff’s theory changes after discovery reveals weaknesses.
Defendants should also investigate public disclosures aggressively. Patent filings by the plaintiff, related inventors, suppliers, or industry participants may show that the alleged secret was already known. Technical literature, product manuals, conference proceedings, and standards documents can be equally important. In trade secret litigation, public information can be a very sharp tool.
Practical Checklist After Coda v. Goodyear
- Define the trade secret narrowly: Identify the exact technical or business information, not merely the product feature or end result.
- Audit public disclosures: Compare the alleged secret against patents, articles, presentations, and marketing materials.
- Preserve confidentiality evidence: Use NDAs, labels, access controls, meeting logs, and document tracking.
- Connect disclosure to use: Build a factual bridge from the secret to the defendant’s conduct.
- Prepare for Rule 50: Trial evidence must support every legal element, not just tell a persuasive story.
- Align patent and trade secret strategy: Decide what to publish and what to keep secret before filing.
How the Decision Fits the Bigger IP Landscape
The Federal Circuit’s ruling fits a broader trend of close judicial scrutiny in intellectual property cases. Courts are willing to respect jury findings, but they are also willing to set aside verdicts when expert testimony, damages models, infringement theories, or trade secret definitions do not meet legal standards. That does not mean trade secret claims are doomed. It means they must be built with discipline.
For innovative companies, the takeaway is not “never share ideas.” Collaboration is essential in manufacturing, software, medical devices, automotive technology, and nearly every serious R&D environment. The takeaway is to share carefully. Define the confidential information before the meeting, mark it clearly, limit who receives it, and maintain a record. If a business cannot describe the secret internally, it will struggle to describe it in court.
Experience-Based Reflections: What This Case Teaches in Real Business Terms
In practical business life, trade secret disputes often begin long before anyone says “misappropriation.” They begin in conference rooms, prototype demos, engineering calls, joint development talks, and “let’s explore synergies” meetings where everyone is smiling and the coffee is still warm. The problem is that innovation conversations are messy. Engineers naturally explain how things work. Business teams naturally push for enough detail to evaluate a deal. Lawyers naturally ask whether the NDA was signed before the slide deck was opened. If nobody manages that process, the company may later discover that its best argument is mostly a memory, and memories are terrible filing cabinets.
One recurring experience in technology disputes is that teams often overestimate how self-explanatory their confidential information is. Inside the company, everyone knows what “the pump placement solution” means. In court, that phrase may be too vague. Judges and juries need the specific mechanism, boundary, dataset, design constraint, or development insight. A trade secret should be described as if the audience is smart but unfamiliar with the internal shorthand. Otherwise, the claim begins to sound like ownership of a concept rather than ownership of secret information.
Another practical lesson is that patent strategy and trade secret strategy must be discussed in the same room. Too often, one team pushes to file broad patent applications while another team assumes certain know-how remains confidential. Months or years later, litigation counsel compares the alleged trade secrets against the company’s own public filings and finds overlap. That is a painful moment. The better approach is to decide early: what goes into the patent system for public disclosure in exchange for potential patent rights, and what stays behind the wall as confidential know-how?
The case also reflects the importance of disciplined meeting hygiene. When companies exchange technical information under an NDA, they should create a clean record of what was shared. That does not mean turning every meeting into a courtroom deposition. It means using dated materials, confidentiality legends, attendance lists, follow-up summaries, and controlled data rooms. If the relationship later breaks down, those ordinary records become extraordinary evidence.
Finally, Coda v. Goodyear is a reminder that litigation storytelling must match legal architecture. A story about betrayal may persuade a jury, but JMOL asks a colder question: does the evidence satisfy the elements? Plaintiffs must prove the existence of a protectable trade secret, reasonable secrecy measures, misappropriation, and use or disclosure where required. Defendants, meanwhile, should test each element separately. The best trade secret cases are not built around outrage. They are built around precision.
Conclusion
The Federal Circuit’s decision affirming JMOL on misappropriation in Coda v. Goodyear is a major reminder that trade secret law rewards clarity. Coda won a large jury verdict, but the verdict could not survive because the asserted secrets were too vague, publicly disclosed, or unsupported by evidence of use. For innovators, the message is not subtle: define the secret, protect the secret, and prove the secret. Anything less may leave even a multimillion-dollar verdict running on flat tires.
