Three Acticon patents survive re-exam; expired patent examined?

Reexamination proceedings at the USPTO were initiated by Askey
Corporation (Askey) in response to a patent infringement law suit brought by Acticon against Askey. Reexamination was requested for three of Acticon's patents: U.S. Patent Nos. 4,603,320 ("Connector Interface"), 4,686,506 ("Multiple Connector Interface") and 4,972,470 ("Programmable Connector"). The Patent Office disagreed with the Askey's arguments alleging that these patents were invalid in view of the prior art.

During the reexamination of the '470 Patent, approximately 120 U.S.
patents, 10 foreign patents, and 34 non-patent publications were brought to the attention of the Patent Office.

Acticon's patents cover specific aspects of "smart connector" devices used in mobile computer communication, networking, and instrumentation control. GPCI has successfully represented Acticon in 22 litigations related to these patents, and has obtained to date 133 licenses and settlements under the patents.

US 4,603,320 (issued July 29, 1986; filed April 13, 1983; why is this being re-examined in 2005? It has expired.) has been cited by 57 US patents.

US 4,686,506 (issued Aug. 11, 1987, filed July 28, 1986) has been cited by 38 US patents. It is a continuation-in-part of application Ser. No. 484,823 filed April 13, 1983, U.S. Pat. No. 4,603,320.
