In Re James R. Amos, Chester K. Greathouse and David S. Riddle

Citations: 953 F.2d 613; 21 U.S.P.Q. 2d (BNA) 1271; 1991 U.S. App. LEXIS 30189; 1991 WL 279387Docket: 91-1298

Court: Court of Appeals for the Federal Circuit; December 30, 1991; Federal Appellate Court

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.

Legal Issues Addressed

Error Requirement for Reissue Applications

Application: The case examines the necessity of demonstrating an error without deceptive intent for a reissue application. The Board found that the supplemental reissue declaration did comply with 37 CFR 1.175(a)(5), providing sufficient detail on the errors.

Reasoning: The Board found that the supplemental reissue declaration did comply with 37 CFR 1.175(a)(5), providing sufficient detail on the errors.

Reissue of Patents under 35 U.S.C. § 251

Application: The legal principle focuses on whether the failure to originally claim certain subject matter constitutes an 'error' under § 251, thus justifying a reissue. The Federal Circuit concluded that the patentees' objective intent alone cannot justify the denial of reissue claims.

Reasoning: The Federal Circuit reversed this decision, stating that a patentees' objective intent alone cannot justify the denial of reissue claims.

Role of Objective Intent in Reissue Claims

Application: Evaluating the role of objective intent, the court emphasized that the presence or absence of objective intent to claim does not alone resolve the inquiry under § 251.

Reasoning: The Court emphasized that the presence or absence of objective intent to claim does not alone resolve the inquiry under § 251.

'Same Invention' Requirement under 35 U.S.C. § 251

Application: This principle assesses whether new claims could have been included in the original patent. The court found that the absence of an 'intent to claim' does not suffice to conclude that the new claims do not relate to the original invention.

Reasoning: The absence of an 'intent' to claim, even if evident from earlier claims or drawings, does not suffice to conclude that the new claims do not relate to the original invention.
