A party is barred (estopped) from raising an issue if the party lost on the issue during the interference. A party may lose on one issue, yet not lose on a different issue.
Example
The applicant lost the interference on a count drawn to a compound, but the opponent lost on a count drawn to methods of using the compound. The applicant may continue to pursue claims to the method of using the compound, but not claims to the compound itself.
