Federal Circuit: Disclaimer based on arguments actually made, not those that could have been made

The scope of surrender is not limited to what is necessary to overcome the prior art reference. Instead, patentees may surrender more than is required to overcome the prior art… Thus, the question is what a person of ordinary skill in the art would understand to have been disclaimed based on the argument actually made, not what one of ordinary skill in the art would have thought was necessary to disclaim the prior art identified. Ultimately, because of the breadth of the disclaimer, the Federal Circuit affirmed the district court’s construction relative to the first disclaimer.
