This is an appeal from the decision of the Patent and Trademark Office Trademark Trial and Appeal Board (“board”),1 dismissing an opposition to the registration of ap-pellee’s “SANDWICH CHEF” and design mark. The board held that there was no likelihood of confusion over the source of the services offered from the contemporaneous use of opposer’s “BURGER CHEF” and “SANDWICH CHEF” in “their natural settings with distinctly different chef caricatures.”2 We affirm.
*877BACKGROUND
Sandwich Chef, Inc. has filed an application 3 for registration of the following service mark.

Burger Chef Systems, Inc. has opposed registration alleging prior use and a likelihood of confusion, mistake, or deception when applicant’s mark is applied to applicant’s services concurrently with opposer’s use of its marks. Appellant’s common-law mark is shown below.

Appellant’s registered marks4 include “BURGER CHEF” and the following.

The board said that, because the services associated with the marks are identical, the only question was whether appellee’s “SANDWICH CHEF” design mark would be equated with or confused with opposer’s “BURGER CHEF” mark “used alone and/or with a chef design.” It opined that, although there could be no dispute that a “burger” is a type of sandwich, the average person upon encountering a “BURGER CHEF” sign or restaurant would recognize and accept it at its face meaning and not attempt to equate the term “BURGER” with the term “SANDWICH.” The board also said that persons seeking or frequenting appellee’s “SANDWICH CHEF” eating places would not be likely to substitute the word “BURGER” for “SANDWICH” either in referring to or in recollecting those eating places.
OPINION
It is well settled that in considering the question of likelihood of confusion, the only relevant application of the law to the facts is in the context of the marketplace, because that is where confusion of prospective purchasers would occur; moreover, all evidence of record bearing on the question of likelihood of confusion must be considered. In re E. I. DuPont DeNemours & Co., 476 F.2d 1357, 177 USPQ 563 (Cust. & Pat.App.1973). The record before us clearly indicates that, in reaching its decision on the question of likelihood of confusion, the board considered all factors listed in DuPont, supra at 1361, 177 USPQ at 567, which are relevant here. The decision is amply supported by the evidence.
*878It is also well settled that, in considering the question of likelihood of confusion, although the involved marks must be regarded in their entireties, it is proper to recognize that one feature of a mark is more significant than the other features and to give greater force and effect to that dominant feature. Martin v. Crown Zellerbach Corp., 422 F.2d 918, 920, 57 CCPA 968, 970, 165 USPQ 171, 172 cert. denied, 400 U.S. 911, 91 S.Ct. 140, 27 L.Ed.2d 151 (1970). See Tektronix, Inc. v. Daktronics, Inc., 584 F.2d 915, 917, 189 USPQ 693, 695 (Cust. & Pat.App.1976). Therefore, appellant’s argument that the board erred in recognizing that the terms “BURGER” and “SANDWICH” are dominant features of the respective marks is not well taken.
Appellant states that the common-law mark and appellee’s mark are “quite similar” and implies that the board failed to consider its common-law mark. At most, the implication amounts to a restatement of the likelihood of confusion issue involving appellant’s common-law mark and designation “BURGER CHEF” compared to the “SANDWICH CHEF” mark. As related above, the board made the proper inquiries, and its decision has ample basis in the record.
Appellant also implies that the board used “an actual confusion” test rather than the test of “likelihood of confusion.” This, too, is without merit. DuPont, supra at 1361, 177 USPQ at 567, expressly states that the nature and extent of any actual confusion, and the length of time during and conditions under which there has been concurrent use without evidence of actual confusion are factors that must be considered, when of record, in testing for likelihood of confusion. Also, it is clear from the board’s opinion5 that it considered the absence of actual confusion as merely one factor in holding that the marks differ “sufficiently ... to preclude a likelihood of confusion.”
Finally, appellant argues that the board failed to resolve doubt in favor of the prior user. However, it does not identify any doubt manifested by the examiner or members of the board, and we have none.
Appellant cites Burger Chef Systems, Inc. v. Burger Man, Inc., 492 F.2d 1398, 181 USPQ 168 (Cust. & Pat.App.1974), in which this court, in reversing the dismissal of an opposition to the registration of the words “Burger Man” with the design of a man as a composite trademark for “drive-in and carryout restaurant services,” recognized:
the circumstances of use of the marks by the parties in chain restaurants catering to the motorist trade where many customers are on the move and in a hurry and often select their eateries on the basis of casual recollection of what they may have experienced in other places at other times, or on the basis of the psychological impact of a TV or radio commercial which may have made a fleeting impression.
However, a case involving the mark “Burger Man” can hardly serve as precedent for a decision involving the mark “SANDWICH CHEF” with a distinct caricature. Interstate Brands Corp. v. Celestial Seasonings, Inc., 576 F.2d 926, 927, 198 USPQ 151, 152 (Cust. & Pat.App.1978); Industrial- Nu-cleonics Corp. v. Hinde, 475 F.2d 1197,1199, 177 USPQ 386, 387 (Cust. & Pat.App.1973).

(d) Consists of or comprises a mark which so resembles a mark registered in the Patent and Trademark Office or a mark or trade name previously used in the United States by another and not abandoned, as to be likely, when applied to the goods of the applicant, to cause confusion, or to cause mistake, or to deceive
