What Is Freedom to Operate?

In evaluating a new invention, it is not sufficient to consider only whether it is patentable. A separate and equally important question is whether the invention can be made, used, or sold without infringing the patent rights of others. This question is commonly addressed through what is referred to as a freedom to operate (FTO) analysis.

An FTO analysis involves identifying patents that are in force and evaluating whether the activities required to practice the invention would infringe those patents.. The focus is on patent claims, which define the legal boundaries of the rights granted. Even if an invention is technically different or independently developed, it may nevertheless fall within the scope of an existing claim.

In practice, freedom to operate is often assessed at later stages of development, when the form of the product or process is clearly defined. However, it is generally advisable to perform an analysis soon after an inventive concept is complete and to repeat the analysis at regular intervals. This is the best way to reduce the risk of devoting a great deal of effort and resources to developing an invention that cannot ultimately be practiced.   

The results of a freedom to operate analysis are inherently limited and should be understood as a form of risk assessment. The results depend on claim interpretation, and may change during prosecution due to  claims in pending applications being allowed. Thus,  although a degree of confidence that an invention will not infringe any third party claims can be developed, certainty is not achievable.

The key point is that freedom to operate addresses a different objective from patentability. A patent gives its owners the right to exclude others, not the right to practice the invention. Accordingly, both patentability and freedom to operate should be considered in forming a realistic view of an invention’s commercial potential.
