proprietary information
UCC / CommercialLegal glossary term
Quick answer
Proprietary information usually means confidential business data belonging to a company. In contracts, it matters because it dictates who can use your trade secrets or client lists. Before signing, check how clearly the agreement defines what counts as 'proprietary.'
Definitions
What is proprietary information?
Legal Definition
Proprietary information describes confidential data belonging to a party, distinguishing it from general public knowledge or common industry facts. This designation grants the owner enforceable rights, allowing them to seek remedies like injunctions or damages when that sensitive business intelligence is misused. Courts often require proof of reasonable steps taken to protect this valuable trade secret.
Plain-English Translation
Proprietary information is like a special stamp on your allowance money; it means only you get to use it exactly as you want. If someone else steals the stamp and spends your cash, they broke the rules.
Contract relevance
Why proprietary information matters in contracts
Misidentifying proprietary information risks losing legal protection; a party might lose their right to seek injunctive relief if they fail to prove confidentiality. The owner of the information bears this risk.
Document context
Where proprietary information appears in documents
| Document type | Section | Why it matters |
|---|---|---|
| Non-Disclosure Agreement (NDA) | Definition section or Confidentiality Clause | It establishes the scope of what must be kept secret. |

| Software License Agreement | Usage Rights Appendix | It protects the source code, algorithms, and customer data embedded in the software. |
| Venture Capital Term Sheet | Representations and Warranties | It assures investors that the company is actively protecting its core assets. |
| Settlement Agreement | Mutual Covenants Section | It prevents the losing party from revealing sensitive operational details to competitors. |
Contract language
Common contract wording
| Contract wording | Plain-English meaning | What to check |
|---|---|---|
| Trade Secrets and Confidential Data | Secret business knowledge, formulas, or client lists | Ensure this covers more than just financial figures. |
| Non-Public Information (NPI) | Any data not generally available to the public | Verify that "publicly known" means *generally* known, not just known by one industry peer. |
| Proprietary Know-How | Specialized expertise or methods of operation | Confirm whether this covers documented processes or only internal thoughts/ideas. |
| Confidential Business Information (CBI) | Broad term for sensitive corporate data | Check if CBI is defined narrowly or broadly to protect maximum assets. |

Pre-signature checklist
What to check before signing
1
Is there a specific list enumerating what qualifies?
2
Does it cover data shared orally (verbal)?
3
Does it define how long the obligation lasts (term)?
4
Does it specify *how* the information must be protected (e.g., encryption, physical lock)?
5
Are both parties bound equally, or is protection one-way?
6
What happens if the data becomes public through no fault of the receiver? (Permitted Disclosure)
7
Is there a carve-out for already existing knowledge prior to disclosure?
Party impact
How proprietary information affects each party
| Party | What this party should check |
|---|---|
| Disclosing Party | Must ensure they take reasonable steps to prove the info *is* proprietary; needs clear definition. |
| Receiving Party | Must understand their obligations (e.g., non-use, non-disclosure); must know which duties apply. |
| Employer | Needs clarity on what IP created by them belongs to the company vs. personal projects. |
| Client/Vendor | Should verify that all shared operational metrics are covered under the umbrella term. |
Comparison
proprietary information vs similar terms
| Related term | Plain meaning | Main difference from proprietary information |
|---|---|---|
| Trade Secret | Information that derives economic value from *secrecy* (e.g., Coca-Cola formula). | Proprietary info can be broader; a marketing plan is proprietary, but not necessarily a trade secret if it's easily reverse-engineered. |
| Intellectual Property (IP) | A broad category covering patents, trademarks, copyrights, etc. | Proprietary information is often the *content* that needs protection; IP is the *legal right* protecting that content. |
| Public Domain Information | Knowledge available to everyone without restriction. | This is the opposite; proprietary info is specifically designated as *not* public. |
Missing or vague
If proprietary information is missing or vague
If you fail to define proprietary information clearly, a dispute erupts over whether a shared spreadsheet counts or if an overheard conversation qualifies. You might spend months litigating whether your client list is truly confidential or just 'industry standard practice.' Without precise language, the court has to guess your intent, and guesses usually favor the party with the better legal team.

| Contract section | What to inspect |
|---|---|
| Definitions Section | Look for a formal definition clause that enumerates examples. |
| Obligations/Covenants | Check what actions are required (e.g., 'shall not disclose,' 'shall protect'). |
| Term and Termination | Look for duration clauses tied to the proprietary data. |
| Remedies/Indemnification | Check what happens when the info is misused (e.g., 'The Disclosing Party shall be entitled to injunctive relief'). |

Document context
How proprietary information shows up in legal documents
Why does it matter?
Misidentifying proprietary information risks losing legal protection; a party might lose their right to seek injunctive relief if they fail to prove confidentiality. The owner of the information bears this risk.
When does it matter?
When a disclosure occurs, the receiving party must immediately classify it as confidential pursuant to contract terms. Furthermore, when misuse happens, the injured party must act promptly within the contractual notice period.
Where is it usually seen?
This concept saturates Non-Disclosure Agreements (NDAs) | standard clauses in SaaS contracts and employment agreements | specific protections under 18 U.S.C. § 1832.
Who is affected?
A franchisor gains control over its recipes when a franchisee signs an agreement, while the subcontractor risks breach of contract if they leak client lists to a competitor.
How does it work?
First, the owner must define what qualifies as proprietary data in writing. Then, they must take active measures—like watermarking or password protection—to maintain that status. Finally, the recipient acknowledges this restriction upon receiving the material.
