FTO Analysis is Necessary for Willful Patent Infringement Claims

When companies develop new products or commercialize new technologies, patent reviews are often treated as little more than a pre-launch checklist. However, the reality is the opposite. FTO (Freedom To Operate) analysis is not merely a procedure to assess the possibility of infringement; it serves as crucial defensive evidence demonstrating that we did not blindly infringe on others' patents when a dispute later arises. The concept of willful infringement, often discussed in practice, points precisely to this issue. Strictly speaking, it is about securing grounds for rebuttal against claims of willful infringement or for negating intent.
Our patent law already imposes significant liability for willful infringement. Article 128 of the current Patent Act allows courts to determine damages up to five times the amount recognized as damages if patent infringement is found to be willful. Furthermore, when determining willfulness and damages, the court considers the infringer's awareness of the potential for damages, the duration and frequency of the infringement, and the efforts made to remedy the harm. Ultimately, this means that the prior reviews and actions taken by a company are directly linked to its liability for damages.
This is precisely why FTO analysis is important. FTO is a procedure to pre-emptively review whether a product or process under development infringes on the claims of others' valid patents. This process involves searching for relevant patents, creating claim charts comparing the claims to the product, and, if infringement is a concern, proceeding to design-around strategies, licensing negotiations, or invalidity assessments. In essence, the nature of FTO is not to respond when a problem arises, but rather to change course before a problem occurs, stop if necessary, and leave a record. Such prior review is effective in preventing disputes, and furthermore, it serves as evidence that a company's decisions were not reckless when a dispute does arise.
Especially in cases where willful infringement is at issue, the court or the opposing party looks at a simple question: Did the company proceed despite knowing about the existence and risks of that patent? One of the most persuasive pieces of evidence a company can present in response to this question is a pre-launch FTO report, and if necessary, an opinion of non-infringement or invalidity. In fact, practical guides provided by government and public institutions explain that conducting FTO analysis and obtaining a legal opinion of non-infringement prior to the infringing act can serve as evidence to prove the absence of subjective intent. Conversely, reports created belatedly after a product has already been launched will inevitably have significantly weaker defensive power.
One more important point here is that the timing of FTO is often more critical than the outcome. Many companies request analysis only after receiving a cease and desist letter, but from the perspective of managing willful infringement risk, this is often too late. The determination of willfulness is ultimately based on the awareness and actions taken at the time of infringement. If a company reviewed the situation before launch, identified risky patents, and consequently modified its design, explored licensing, or adjusted its launch scope, that itself demonstrates good faith and due diligence. On the other hand, a company that launches without any prior review and then seeks to create an opinion letter after a dispute arises will find it difficult to dispel suspicions of proceeding with knowledge.
A good FTO analysis in practice is not just a simple search report. Its scope and depth must vary depending on factors such as the target country of business, the specifications of the product actually planned for sale, whether the manufacturing process needs to be reviewed, and whether the report is for submission to clients or for internal decision-making. Furthermore, FTO should not end with a legal document. If potentially infringing patents are identified, design-around instructions should be issued, invalidity data should be collected if necessary, and licensing negotiations should be pursued concurrently in some cases. Only then does FTO become substantive risk management rather than a formal review. And that is precisely what provides the strongest defense against future claims of willful infringement.
Ultimately, the value of FTO analysis lies on two levels. First, it naturally serves to prevent patent infringement. Second, and equally importantly, it serves to pre-emptively block the frame of willful infringement. Today, patent disputes are not merely legal issues but business matters directly impacting business continuity, investment, transactions, and exports. Therefore, FTO is not an expense but insurance, or more accurately, a record proving how prudent and rational a company's decisions were when a dispute occurred.
Pine IP Firm advises companies to view FTO not as a mere search task, but as a process that simultaneously designs launch strategy and dispute defense strategy. In an era where willful patent infringement is a concern, a single, well-prepared FTO report left behind before commercialization can become the strongest defense argument in litigation.
