From Know-How to Asset: Where Trade Secrets Break Down

Why Vague Trade Secrets Are Worth $0
“Void for vagueness” is a legal doctrine under which poorly-defined laws can be struck down. The same principle quietly governs trade secrets: if the definition of your trade secret is not precise, the asset fails—and you have nothing.
The case of Coda Development v. Goodyear Tire & Rubber centered around self-inflating tire technology—systems designed to automatically maintain tire pressure through pumps, valves, and internal air-pathways embedded within the tire.
Coda claimed that its proprietary know-how regarding the design and placement of these systems constituted legally protectable "trade secrets" and that Goodyear misappropriated those trade secrets. A jury agreed, awarding Coda $64 million.
However, the victory was short-lived, as the district court set the verdict aside. The Federal Circuit affirmed this decision—not due to a technicality, but because Coda never clearly defined what its trade secrets were.
Trade Secrets Protect Know-How, Not Outcomes
Trade secrets do not protect broad ideas; they protect specific, identifiable knowledge:the concrete "how" that enables a skilled third party to replicate something.
Coda's purported 'trade secrets' were framed as "knowledge of how to design and develop" components of a self-inflating tire system. However, upon closer examination, they reduced to:
1. Lists of features,
2. Inventories of components, and
3. Descriptions of system functions.
What was missing? The enabling know-how that actually makes a system buildable.
As the Federal Circuit put it, describing the functions a product performs is not the same as identifying the proprietary knowledge required to create it.
How a Definition Killed a $64 Million Verdict
One instructive failure involved a claimed trade secret regarding the "optimal" location of a pump (located inside a tire—near the sidewall and rim).
The problem? Coda had already disclosed that placement years earlier in a patent application and a trade journal article.
During the trial, Coda attempted to narrow the definition by adding qualifiers—arguing it meant placement in a "conventional" tire. However, the court rejected this outright because those limitations were not part of the original definition. You can't retrofit specificity once litigation begins.
Define a trade secret too broadly, and you capture public information.
Try to narrow it later, and you admit it was never properly defined.
Either way, you lose.
The Real Business Lesson
This case illustrates how companies fail to treat trade secrets as commercial assets.
Coda had real work: prototypes, test data, publications, patents, and serious industry discussions. However, it never clearly articulated what its proprietary know-how actually was in a way that could survive scrutiny—legal or commercial.
And that leads to the lesson most companies miss:
If you can't clearly identify your trade secrets, you can't commercialize them.
A lack of clear definition means:
No clean licensing scope,
No defensible valuation,
No credible diligence story, and
No leverage in negotiations.
Identifying trade secrets isn't just about avoiding litigation; it's about asset formation.
Trade Secret Litmus Test
If you want trade secrets to generate ROI, you should be able to answer—clearly and in writing:
What exact knowledge is secret (not what the product does)?
How is it different from what you've already made public?
Could a competent third party build the system using this information?
Where does this knowledge appear in a product, license, or deal?
If you can't answer these questions, you don't have trade secrets.
You have undocumented tribal knowledge and hope.
Our Perspective
At Meridian Cay Advisors, we help close this gap. We work with companies to identify, define, and structure proprietary know-how before it undergoes scrutiny—by partners, competitors, or courts. This involves inventorying trade secrets, clearly distinguishing them from public disclosures, and transforming technical knowledge into defensible, monetizable IP assets.
Trade secrets don't create value just by existing. They create value when they're defined with enough precision to matter.
