The Freedom to Operate (FTO) search focuses on the market and on the potential to commercialize the patent. The FTO is usually more time intensive than other searches because the focus is not on prior art but on the exact claims of existing patents, and the process involves scrutinizing all claims related to the patent. In case of there being any potential infringement, the client may choose to go for alternative options such as revision of the invention or licensing. A Non-Infringement search is similar to the FTO search, but focuses on specific patents instead of a given landscape. This is more focused than the FTO search, and is usually used in cases where the inventor or patent attorney is aware of similarities within an existing patent.
