Unfortunately, at the present time, there is no way. However, having multiple issued patents on similar technologies can sometimes dissuade a prospective IPR challenger due to the fact that a single IPR challenge ordinarily costs $300,000 - $500,000. Thus, the costs of litigation get progressively more expensive with each patent that the IPR challenger must invalidate in order to avoid infringement. The average cost of litigating an IPR challenge is usually helpful information for the patentee, whose goal is often to secure a license from the alleged infringer without going to court. In many cases, if the cost of a license is less than the cost of litigating n IPR challenges, the alleged infringer will just pay the license. This may also motivate a patent plaintiff to sue clients individually, rather than jointly, because joint defendants sometimes share the costs of joint defense -- such as the costs of bringing IPR challenges.
