UCC / CommercialLegal glossary term
Quick answer
Proprietary information usually means confidential business assets with competitive value. In contracts, it matters because unauthorized disclosure can lead to significant liability. Before signing, check what qualifies as proprietary and how long protection lasts.
Definitions
What is proprietary information?
Legal Definition
Proprietary information represents confidential business assets that provide competitive advantage. This information is protected by law through trade secret statutes and contractual obligations to maintain secrecy. The key qualifier is that protection requires reasonable efforts to maintain confidentiality.
Plain-English Translation
Proprietary information is like a secret recipe you share with a friend on the condition they don't tell anyone else. If they share it, you can demand they stop and possibly compensate you.
Contract relevance
Why proprietary information matters in contracts
Misappropriating proprietary information can lead to injunctions and substantial damages. The party who disclosed or used the information without authorization bears the risk of litigation and financial liability.

Comparison
proprietary information vs similar terms
| Related term | Plain meaning | Main difference from proprietary information |
|---|---|---|
| Trade secrets | Protected information with actual or potential economic value | Must provide competitive advantage and be subject to reasonable secrecy efforts |
| Confidential information | Information requiring protection but not necessarily proprietary | May not have the same level of legal protection or commercial value |

| Intellectual property | Legal rights over creations of the mind | Includes copyrights, patents, trademarks beyond just confidential business information |
Missing or vague
If proprietary information is missing or vague
If proprietary information is undefined in a contract, parties may disagree about what qualifies as protected information. This can lead to disputes over whether certain customer lists or technical processes are covered by confidentiality obligations. Vague definitions may also result in litigation over whether unauthorized disclosure occurred or if information became public through no fault of either party. Without clear boundaries, enforcing protection becomes significantly more difficult and costly.

Document context
How proprietary information shows up in legal documents
Why does it matter?
Misappropriating proprietary information can lead to injunctions and substantial damages. The party who disclosed or used the information without authorization bears the risk of litigation and financial liability.
When does it matter?
When a party receives proprietary information, confidentiality obligations immediately attach. Within 30 days of receiving such information, recipients must typically execute formal nondisclosure agreements.
Where is it usually seen?
Proprietary information appears in nondisclosure agreements, employment contracts, and merger agreements. Courts apply trade secret protections in both state courts (under UTSA) and federal courts (under DTSA).
Who is affected?
Disclosing parties gain competitive protection but risk accidental leaks. Receiving parties gain access to valuable information but face legal exposure if they misuse or improperly disclose it.
How does it work?
First, a party identifies information as proprietary and marks it confidential. Then, the receiving party acknowledges receipt and accepts confidentiality obligations. Finally, if misuse occurs, the owner can seek remedies through litigation or arbitration.
