Sharp Kabushiki Kaisha, also trading as Sharp Corporation, (“Sharp”) appeals the decision of the United States Patent and Trademark Office, Trademark Trial and Appeal Board, dismissing Sharp’s opposition to the registration by ThinkSharp, Inc. (“ThinkSharp”) of the mark THINK-SHARP. 1 We affirm the Board’s decision.
BACKGROUND
ThinkSharp filed an application to register the word mark THINKSHARP on February 26, 1999, and filed a second application to register the mark THINK-SHARP and Design on June 4, 1999. Both marks were designated for use with educational goods and services in the fields of problem solving and critical thinking, and both applications were duly published for opposition. Sharp filed a Notice of Opposition to the word mark registration on May 9, 2000, and to the word-and-design registration on June 28, 2001. In both cases Sharp asserted that THINK-SHARP is confusingly similar to and dilutes the family of SHARP trademarks.
ThinkSharp chose to defend only the word mark registration and did not file an answer in the word-and-design opposition. Thus the Board entered a default judgment sustaining Sharp’s opposition to the word-and-design mark. Sharp Kabushiki Kaisha v. ThinkSharp, Inc., Opposition No. 91123480 (TTAB Oct. 11, 2002) (default judgment). However, ThinkSharp contested Sharp’s opposition to registration of the word mark THINKSHARP. After the TTAB proceedings were completed but before the Board’s decision, Sharp asserted that the default judgment in its favor on the word-and-design mark operated as res judicata to preclude ThinkSharp from contesting Sharp’s opposition to registration of the word mark.
*1370 The Board rejected Sharp’s opposition, on two grounds. First, the Board held that Sharp had waived its right to assert res judicata, stating that Sharp had not put ThinkSharp on notice and had not raised the issue until after the TTAB evi-dentiary proceedings were completed. On the merits, the Board held that confusion was not likely between the word marks SHARP and THINKSHARP. Sharp asked the Board to reconsider. On the res judi-cata issue, Sharp pointed out that it had properly raised and given notice of the issue, and produced a copy of a letter to the Board with copy to ThinkSharp, which stated that Sharp intended to rely on the default judgment for res judicata effect. The Board then granted reconsideration, explaining that Sharp’s notice letter had been misplaced at the Board.
On reconsideration, the Board observed that the ThinkSharp applications were co-pending; the Board held that the applicant was entitled to choose to pursue one registration and abandon the other, even after oppositions had been filed. The Board explained that an applicant is not required to defend against multiple oppositions in order to preserve its right to defend against one of them. Thus the Board held that the default judgment on the word- and-design mark did not preclude defending the application to register the word mark. The Board also confirmed its decision that there was not a likelihood of confusion between SHARP and THINK-SHARP. Sharp appeals only the decision of the issue of res judicata.
DISCUSSION
Whether a particular claim is barred by
res judicata
is a matter of law, and its decision by an administrative agency receives plenary review.
See
5 U.S.C. ’706(2)(A) (2006) (“The reviewing court shall hold unlawful and set aside agency [conclusions] not in accordance with law ....”);
Dickinson v. Zurko,
The term res judicata includes two related concepts: “claim preclusion” and “issue preclusion.” The Court has explained the difference between them:
Res judicata is often analyzed further to consist of two preclusion concepts: “issue preclusion” and “claim preclusion.” Issue preclusion refers to the effect of a judgment in foreclosing relitigation of a matter that has been litigated and decided. This effect is also referred to as direct or collateral estoppel. Claim preclusion refers to the effect of a judgment in foreclosing litigation of a matter that never has been litigated, because of a determination that it should have been advanced in an earlier suit. Claim preclusion therefore encompasses the law of merger and bar.
Migra v. Warren City Sch. Dist. Bd. of Educ.,
A default judgment can operate as
res judicata
in appropriate circumstances.
See Morris v. Jones,
ThinkSharp argues that the Board was correct in holding that the circumstances concerning the word-and-design mark do not operate as
res judicata
for the proposed registration of the word mark. Sharp raises the issue of claim “preclusion,” not to preclude a claim asserted by ThinkSharp against Sharp, but rather to support its opposition.
See
37 C.F.R. § 2.116(c) (“The opposition or the petition for cancellation and the answer correspond to the complaint and answer in a court proceeding”). The Supreme Court has cautioned that the offensive use of
res judicata
should be examined carefully to determine whether it would be unfair to the defendant.
See Parklane,
The Board held that ThinkSharp was entitled to choose to pursue the registration of only one of its marks, “rather than defending two oppositions,” and distinguished the Board precedent cited by Sharp, as follows:
This case, however, differs from Miller Brewing Co. v. Coy International Corp. [230 USPQ 675 , 678 (TTAB 1986)] in that this is not a situation where the applicant, after a judgment had been entered against it, adopted a second mark in an attempt to avoid the preclu-sive effect of a previous judgment. The applicant herein began using both its THINKSHARP (typed drawing form) and THINKSHARP and design marks at the same time and indeed both applications were pending at the time judgment was entered in Opposition No. 91123480. Applicant did not file its application to register the mark THINK-SHARP in typed drawing form merely as an attempt to evade the preclusive effect of the judgment entered against it in the application to register THINK-SHARP and design. Applicant was entitled to decide if it wanted to pursue the registration of only one of its marks, rather than defending two oppositions.
2004 TTAB LEXIS 659, at *5-6. In
Miller Brewing
the Board held that it “does not wish to encourage losing parties to insignificantly modify their marks after an adverse ruling and thereby avoid the
res judicata
effect of the prior adjudication.”
*1372
It is highly relevant that the default judgment on the word-and-design mark was entered without consideration of the merits. “Precedent cautions that
res judi-cata
is not readily extended to claims that were not before the court, and precedent weighs heavily against denying litigants a day in court unless there is a clear and persuasive basis for that denial.”
Kearns v. Gen. Motors Corp.,
When applying res judicata to bar causes of action that were not before the court in the prior action, due process of law and the interest of justice require cautious restraint. Restraint is particularly warranted when the prior action was dismissed on procedural grounds.
The purpose of
res judicata
is salutary, for it protects a party from being required to relitigate the same issue against the same party in a separate action.
Parklane,
We affirm the Board’s holding that ThinkSharp’s choice to contest only the word mark opposition was not barred by the default judgment in the word-and-design opposition. ThinkSharp was not required to litigate both oppositions in order *1373 to preserve the right to litigate one. The Board’s decision that res judicata does not apply is
AFFIRMED.
