Changing jobs is common in today’s workforce, but employees often wonder what information they can legally take with them when joining a new employer. Yes, it is illegal to use a former employer’s trade secrets after leaving a job in Pennsylvania if the information qualifies as a protected trade secret and is used or disclosed without authorization. Pennsylvania law provides strong protections for businesses against the misappropriation of confidential information, and employees who improperly use trade secrets may face civil lawsuits, financial damages, injunctions, and, in some circumstances, even criminal consequences. However, employees remain free to use their general knowledge, skills, and experience acquired during their employment.
What Counts as a Trade Secret in Pennsylvania?
A trade secret is valuable business information that derives economic value from not being publicly known and is subject to reasonable efforts by its owner to keep it confidential. Pennsylvania follows the Pennsylvania Uniform Trade Secrets Act (PUTSA), which protects qualifying trade secrets from unauthorized acquisition, disclosure, or use.
Examples of trade secrets include:
- Customer lists developed through substantial effort.
- Manufacturing processes and proprietary formulas.
- Pricing strategies and profit margins.
- Marketing plans and product development roadmaps.
- Software source code and proprietary algorithms.
- Confidential supplier agreements and business strategies.
Information that is publicly available or generally known within an industry is typically not considered a trade secret.
What Is Considered Illegal Use?
Using a former employer’s trade secrets without permission after changing jobs may constitute trade secret misappropriation. Illegal conduct can include copying confidential files before resigning, emailing sensitive documents to a personal account, downloading proprietary databases, sharing confidential information with a new employer, or using protected information to compete against the former employer.
Importantly, an employee does not need to physically steal documents to violate the law. Even intentionally disclosing confidential information learned during employment can result in legal liability if the information qualifies as a protected trade secret.
Can You Use Knowledge and Experience?
Yes. Pennsylvania law distinguishes between protected trade secrets and an employee’s personal knowledge, education, professional skills, and experience.
For example, a software engineer may use programming skills learned over years of employment, while a salesperson may rely on general sales techniques and industry knowledge. However, using confidential customer databases, proprietary software code, or secret pricing formulas belonging to a former employer is a different matter and may violate trade secret laws.
The distinction often depends on whether the information is unique, confidential, and economically valuable because it remains secret.
Legal Consequences for Misusing Trade Secrets
Businesses whose trade secrets have been misappropriated may file a civil lawsuit seeking several remedies.
Potential consequences include:
- Court orders prohibiting further use or disclosure of the trade secret.
- Monetary damages for financial losses.
- Recovery of profits unjustly earned through misuse.
- Exemplary damages in cases involving willful or malicious misconduct.
- Payment of attorney’s fees in certain circumstances.
In particularly serious cases involving theft of trade secrets for commercial advantage, criminal laws at the federal level may also apply.
Employer Responsibilities
Not every piece of confidential information automatically qualifies as a trade secret. Employers generally must demonstrate that they took reasonable measures to protect the information. Common protective measures include confidentiality agreements, restricted computer access, password protection, employee training, secure storage systems, and clearly marking sensitive documents as confidential.
If a business fails to safeguard its information, it may have greater difficulty proving that the information deserves trade secret protection.
Best Practices for Employees Changing Jobs
Employees planning to join a competitor should avoid copying confidential documents, downloading company files, forwarding business emails to personal accounts, or retaining proprietary materials after leaving employment.
Instead, return all company property, comply with confidentiality agreements, rely only on your own skills and publicly available information, and seek legal guidance if uncertain about whether certain information may be protected.
Conclusion
Using a former employer’s trade secrets after leaving a job in Pennsylvania is generally illegal when the information qualifies as a protected trade secret and is used without authorization. While employees are free to build upon their experience and professional expertise, they cannot exploit confidential business information that belongs to a former employer. Understanding the distinction between general knowledge and legally protected trade secrets helps both employees and employers avoid costly disputes and ensures fair competition in the marketplace.
