Temporary Use of Unlicensed Software: Legal Liability Regardless of Duration

Companies often argue, during audits, that the use of unlicensed software occurred only briefly—over a few days or weeks—as a way to minimize or avoid liability for compensation equivalent to the market value of an original license. However, this argument has no legal foundation. The unauthorized exploitation of intellectual property, regardless of its duration, constitutes both a civil and criminal offense.

Brazil’s Law No. 9.609/1998 (Software Law) states in Article 9 that reproducing a computer program, in whole or in part, without authorization from the rights holder is prohibited, except in expressly allowed circumstances. Article 12 further imposes penalties ranging from six months to two years of detention or a fine for violations. Additionally, Law No. 9.610/1998 (Copyright Law) in Article 102 grants the copyright holder the right to seek the seizure of illegally reproduced materials and halt their distribution, without prejudice to compensation for damages.

Brazilian courts have repeatedly upheld the view that even short-term or sporadic unauthorized use of software constitutes unlawful conduct and gives rise to civil liability. Case law confirms that arguments based on the limited duration of use or low financial impact are irrelevant. Legal damage arises not from the frequency or intensity of use, but from the fact that the protected work was used without permission. Economic exploitation of software without a valid license does not require recurrence to qualify as infringement—it is sufficient that the exclusive right of the copyright holder was violated.

Beyond compensating the rights holder, the company may also be subject to search and seizure of its equipment, formal legal notices, or even criminal proceedings initiated by the Public Prosecutor’s Office in cases involving willful conduct or significant commercial benefit. Companies that neglect software license compliance also run the risk of reputational harm, the loss of partnerships, and diminished trust from investors or clients.

This is not merely a legal issue—it is an ethical and strategic one. Claiming ignorance or attempting to downplay the violation based on its duration does not change the fact that a clear infringement of intellectual property rights occurred. There is no “grace period” or tolerance window under Brazilian law for unauthorized use of protected works, nor is liability scaled according to the number of days of use. Whether it lasted a single day or a year, the legal consequences are the same.

For these reasons, organizations must implement strict software compliance policies, maintain updated license inventories, and regularly train their employees. Prevention remains the most effective strategy to avoid the legal and operational risks associated with the use of unlicensed software. Companies should also consider having an internal reporting mechanism and rapid response procedures to contain any irregular use before it escalates into a formal legal dispute.

Respecting intellectual property rights should be part of a company’s culture. Organizations that value integrity and legal compliance reduce their risk exposure while strengthening their credibility and stakeholder trust. In short, temporary use of pirated software is not a minor slip—it is a full legal violation with consequences clearly defined by law, and it must be addressed with the seriousness it deserves.
