Patent enforcement can be a powerful way to protect innovation and recover lost value, but it is also one of the most expensive legal processes an inventor can face. For many patent owners, the cost of traditional litigation makes enforcement unrealistic, even when infringement is clear. This challenge has led to the rise of contingency patent litigation, a model in which attorneys assume the financial risk and are paid only if the case succeeds. However, not every patent qualifies for this type of representation. Understanding what makes a patent suitable for contingency litigation is essential before pursuing enforcement.
