Most practitioners are well aware that disputes with the USPTO over formal oath requirements in patent reissue are the rule, not the exception. I have written extensively in the past as to the significant delays caused by this seemingly straight forward formal requirement.
In most cases, the dispute relates to a lack of specificity in identifying the error to be corrected in the patent reissue application. While in many cases the correction necessary is relatively minor. However, in most cases the objection raised relative to the oath does not come from the examiner, but instead, a Quality Assurance Specialist (QAS) of the USPTO. Thus, it is not uncommon to contact the examiner to request a recommended change to an oath to finally settle the dispute only to have the examiner inform you “I think it’s fine, but the QAS has some issue that I don’t really understand.” This leaves the Patentee with no efficient means to address the problem in a timely manner. This type of roadblock is especially aggravating in broadening patent reissue applications.
