Narrative Opinion Summary
This case revolves around a reissue application for U.S. Patent No. 4,610,582, which involves a mechanism of rollers for a router. The patentees originally failed to claim a computer-based control system for the rollers, which they later sought to include in claims 10 through 12 of the reissue. The U.S. Patent and Trademark Office (PTO) Board denied these claims, stating they did not arise from an 'error' under 35 U.S.C. § 251. The Board argued that the original patent did not indicate an intent to claim the computer control system. On appeal, the Federal Circuit reversed the Board's decision, emphasizing that the lack of 'intent to claim' was not sufficient to deny reissue. The court highlighted that the statute's 'same invention' requirement does not limit reissue to previously claimed subject matter if an inadvertent error is established. The Federal Circuit underscored that objective intent to claim is not a determinative factor for reissue eligibility. The outcome enabled the patentees to pursue the reissue claims, broadening the scope of their patent to include the computer-based control initially overlooked due to attorney error.
