In particular, the average patent lawsuit in the United States costs approximately $3 million in legal fees alone. Additional expenses, including assessments, appraisals, judicial reports, etc. they can add an additional million dollars. A newer solution for those who are unable to fund their own causes is something called "third-party funding." The most common candidates include individual inventors, small entities, and universities as they generally do not have the financial resources to self-fund a patent lawsuit. Before considering this option, you will want to consider the factors associated with receiving funding and going through the patent litigation process. One of the reasons patent litigation is so risky is that, if the defendant in the lawsuit can find some sort of prior product with a similar situation created before your patent was obtained, then a court could declare your patent invalid after the fact. Therefore, you have now spent money to obtain the patent and invested in a third party to finance it
