Court | Patent Trial and Appeal Board |
Before RICHARD TORCZON, SALLY MEDLEY, and KARL D. EASTHOM Administrative Patent Judges.
EASTHOM, Administrative Patent Judge.
This proceeding arose from a third party request on behalf of Thomas & Betts Corporation (T&B) for an inter partes reexamination of U.S. Patent 6, 984, 791 Bl. Appellant, patent owner Cooper Technologies Company, appeals under 35 U.S.C. §§ 134(b) and 306 from the Examiner's Right of Appeal Notice (RAN) rejecting claims 1-30. (App. Br. 1-2.) The Examiner's Answer incorporates by reference the findings from the RAN. Requestor's appeal is hereby dismissed because the Cross Appeal Brief is untimely and has not been entered. (See Decision Granting Petition 11, Nov. 18, 2008.) We have jurisdiction under 35 U.S.C. §§ 134(b) and 306.
We affirm.
STATEMENT OF THE CASE
Appellant appeared before the Board on August 3, 2011 at a hearing involving the appeal of this inter partes reexamination and a related ex parte reexamination . The two patents at issue in the reexaminations were the subject of prior litigation, Cooper Tech. Co. v. Thomas & Betts Corp., No. 2.06-CV-242 (E.D. Tex. 2009), involving the same parties in which a jury found certain of the claims in both patents invalid based in part on the same prior art as is involved here. After the verdict, the parties settled and the judge dismissed the action without prejudice without entering a final judgment on January 23, 2009. (See Ans. 2; BPAI Tr. 2.)
Requestor has not participated in the reexamination proceeding since the judgment. After the judgment, Appellant raised the issue in the reexaminations of whether prior art documents involved in the litigation and here constitute printed publications. (See BPAI Tr. 7-8.) In particular, Appellant challenges whether the Elastimold Brochure (describing T&B's bushing/terminator connector products), the RTE Manual (describing Cooper's bushing/terminator connector products), and the Stanger paper (describing generic bushing/terminator connector products) were publically disseminated. (Reb. Br. 6-7.) The record reflects that these documents were not challenged on this basis during the litigation. (See, e.g., BPAI Tr. 7 ( ).)
Appellant also challenges whether these documents anticipate the claims at issue here, or render the claims obvious (in view of other prior art as mitigated by secondary considerations of nonobvious). The art based issues involve a color band on a bushing connector which serves to indicate that a terminator connector is fully latched with the bushing connector.
The 791 Patent[1]
P1. The '791 patent describes a bright color band which indicates when two parts of a high voltage electrical connector device have been fully latched together. The dual parts include a female bushing with a bright yellow band near one end and an annular latching groove near the other end. (See infra P4.) When an operator pushes a male elbow terminator into and over the bushing, the bushing color band completely disappears inside an annular cuff on the closest mating end of the terminator. The terminator 10 has a male electrical connector probe 20 surrounded by an insulative socket 14 which surrounds the female bushing 12 upon latching. (See Fig. 1.) Full latching occurs only when an annular latching ring on the terminator snaps into the corresponding annular latching groove on the bushing.
This complete disappearance of the color band upon latching corresponds to "a visual indication of positive latching, " according to the claims in dispute. (See, e.g., claim 1 and further discussion infra.)
P2. The '791 patent describes the color band (see Fig. 5- P4 infra) as follows:
The color band 114 can be applied in any suitable manner, preferably by applying a colored ink by means of a roller traveling around the outer periphery of the tongue. The band 114 is preferably circumferentially continuous, but it could be interrupted as well, since it is only required that the band be at least partly visible when there is no positive latching and be invisible when there is positive latching.
"Preferably, the band color is of a highly visible nature, such as a bright dayglow color like yellow, orange . . . which is readily visible from at least a three to five foot distance."
P3. "The present invention relates to the interconnection of electrical distribution elements and, in particular, to the interconnection between a loadbreak elbow terminator and a bushing." Unlatched conditions can be potentially dangerous and difficult to visually detect, since for safety reasons, an operator may be standing remotely from an elbow and terminator. "It would therefore be desirable to facilitate the ability of the operator to detect an unlatched condition, especially when standing remotely of the terminator and bushing." (Col. 1, 11.52-55.) To facilitate that detection, "when positive latching has occurred, the color band 114 will be completely disposed within the socket portion 115 and no longer visible."
P4. Figure 5, depicting a bushing from the '791 patent, as modified by the Examiner (Ans. 33), appears next:

Figure 5 supra depicts a second bushing embodiment of the disclosed invention having a color band of limited width W. The color band "sharply contrasts with that of an adjacent portion 120 of the tongue 118 and also with that of the outer surface of the flange 116" on the terminator.
(App. Br. Claims App'x (emphasis added).)
The References
The Examiner employs the following references:
The Examiner adopted or entered the following rejections:
Claims 1-30 stand rejected under 35 U.S.C. § 102(b) as being anticipated based on either the Elastimold Brochure or the Stanger Paper, or under 35 U.S.C. § 103(a) as being obvious based on either the Elastimold Brochure or the RTE Manual, and Yamamori.
Appellant's arguments and the Examiner's findings raise the following issues:
Assuming arguendo that Appellant timely raises the dissemination issue, did the Examiner meet the prima facie burden of establishing that the Elastimold Brochure and the RTE Manual were publically disseminated?
Did the Examiner err in finding that the Elastimold Brochure has a bushing color band that only completely disappears in the elbow terminator, after, and not before, full latching occurs?
Did the Examiner err in finding that it would have been obvious, in view of Yamamori's color band, to modify the bushings in the RTE Manual or the Elastimold Brochure to include a similar color band?
