This was the case in the past. Recently one of my lawyers suggested that this is not necessarily the case at present. The USPTO appears to be (slowly) getting its act together. While USPTO behavior has been rent-seeking in recent years, preferring to issue stupid patents rather than risk being sued by the applicant, the frequency of re-examination requests during court proceedings has increased substantially and is providing more of a counterbalancing interest. In this case there are only applications, not actual patent claims. The applicant is obliged to provide any information received that might affect the validity of the patent to the USPTO. Failure to do so can lead to the patent being invalidated. So it is not a question of a re-exam. As always, IANAL and this is not legal advice.
