How to Legally Protect Proprietary Business Information and Trade Secrets in Wisconsin

Your business's most valuable assets are often intangible. From customer databases to secret manufacturing techniques, proprietary information gives you a competitive edge. However, if an employee leaves and takes this information to a competitor, you can only protect your business if you have taken preemptive legal steps. By understanding the Wis. Stat. § 134.90, you can establish strong defenses without having to step foot in a courtroom. A local lawyer from our directory can help you draft the necessary policies to keep your secrets safe.

Protecting Different Types of Business Assets

Not everything qualifies as a trade secret. To be protected, the information must derive independent economic value from not being generally known, and you must make reasonable efforts to maintain its secrecy. Here is how this applies across different Wisconsin industries.

Client Lists for Sales Agencies

For B2B sales agencies and marketing firms, a client list is the lifeblood of the business. However, a simple list of names and addresses you can find online is not a trade secret. To protect your list, it must contain unique, non-public data, such as purchasing history, key decision-maker contact preferences, and negotiated pricing tiers. You protect this by requiring all sales staff to sign strict Non-Disclosure Agreements (NDAs) and restricting database access only to employees who need it to perform their jobs.

Recipes for Restaurants and Breweries

Wisconsin has a rich culinary and brewing history. A unique beer recipe or a signature restaurant sauce can be a highly guarded secret. Unlike patents, trade secrets do not expire as long as they remain secret. To protect a recipe, you should split the preparation steps among different employees, lock physical recipe cards in a safe, and never share the complete formula with outside vendors. Courts look favorably on businesses that physically restrict access to their core formulas.

Manufacturing Processes

If your factory has developed a faster, more efficient way to assemble a product, that process is a trade secret. Preemptive protection involves physical security. You should restrict visitor access to the manufacturing floor, prohibit cell phones or cameras in sensitive areas, and label specialized machinery schematics as confidential. In cases like Minuteman, Inc. v. Alexander, 147 Wis. 2d 842 (WI Supreme Court 1989), the courts heavily analyze the physical and administrative barriers a company uses to protect its methods.

Software Algorithms

Tech startups often rely on proprietary code. Protecting algorithms requires digital security measures. This includes using encrypted servers, enforcing two-factor authentication, and utilizing 'need-to-know' access controls. Additionally, when sharing code with third-party testers or investors, you must use strong confidentiality agreements before any data is transferred.

WUTSA Compliance and Reasonable Efforts

The core of the Wis. Stat. § 134.90 is the concept of 'reasonable efforts.' If you do not actively protect your information, the law will not protect you when it is stolen. A judge will not punish an ex-employee for taking a client list if that list was left sitting on a public counter. Reasonable efforts include password-protecting computers, marking documents as 'CONFIDENTIAL', conducting exit interviews to remind departing employees of their obligations, and implementing a Written Information Security Program (WISP).

Cost of a Written Information Security Program (WISP)

A WISP is a formal, written manual that dictates exactly how your company stores, handles, and disposes of sensitive information. Having a WISP is one of the strongest ways to prove you took reasonable efforts to protect your secrets.
