342 F.2d 1019
AMERICAN DRILL BUSHING COMPANY, Appellant,v.ROCKWELL MANUFACTURING COMPANY, Appellee.
Patent Appeal No. 7348.
United States Court of Customs and Patent Appeals.
April 8, 1965.

Vernon D. Beehler, Los Angeles, Cal., for appellant.
John D. Nies, Washington, D. C., for appellee.
Before RICH, Acting Chief Judge, and MARTIN, SMITH, and ALMOND, Judges, and Judge WILLIAM H. KIRKPATRICK.*
MARTIN, Judge.


1
Appellant, American Drill Bushing Company (hereinafter American), has appealed from a decision adverse to it in two oppositions, Nos. 40,957 and 41,517. Appellant filed for registration of DELTA-GRIP, serial No. 106,304 filed October 13, 1960 for use on drill bushings, first use as of January 1, 1954 being alleged, and for registration of DELT A LINER,1 serial No. 108,739 filed November 21, 1960 for use on drill bushings, drill blocks, and drill jigs,2 first use in commerce as of October 4, 1960 being alleged.


2
Appellee Rockwell Manufacturing Company (hereinafter Rockwell) opposed on the basis of its registration and use of the mark DELTA as such or in combined forms DELTAGRAM, DELTA MILWAUKEE, DELTACRAFT, and DELTA ROCKWELL, for power tools of various types.3 After consolidation, testimony in the form of affidavits was taken by both parties. The board subsequently sustained the oppositions and refused the registrations sought by American. There is no issue of priority. The single issue is likelihood of confusion between the marks as applied to the respective goods of the parties.


3
A reproducible accuracy in drilling is called for in certain mass production manufacturing operations. To achieve such accuracy drill jigs are used. In such jigs the drill bit of the drill press is guided, as it is fed into the workpiece, through a hardened bushing cast into a block.


4
Appellant is a specialist in the manufacture of the drill bit guiding bushings, or drill bushings, and has sold them under a family of "A" marks, A, HEX A GRIP, SERR A GRIP, THERMA-GRIP,4 and now seeks registration of DELTA-GRIP5 and DELT A LINER for such bushings. The family of marks corresponds to different styles and types of bushings having reference to surface characteristics, textures and technical differences. The greatest users of appellant's bushings are large manufacturers which purchase them in quantity lots. Substantially 90% of the bushings under the mark DELTA-GRIP are sold at prices from $1.25 to $1.95 each. All of appellant's advertising is confined to trade journals.


5
Appellee has manufactured power tools, including drill presses and drill bits and other drill press components and accessories, since long prior to January 1, 1954 under the mark DELTA.6 During the period from 1947 through 1961, appellee has expended over eleven million dollars in the advertising of DELTA power tools of all types.


6
The board held the marks to be substantially similar, stating:


7
"Applicant's marks `DELTAGRIP' and `DELT A LINER' incorporate opposer's mark `DELTA' in its entirety. The designation `DELTA' or `DELT A' is wholly arbitrary as applied to the goods of the parties."


8
Appellant contends that the marks are in fact distinct and different since it uses a three syllable combination in both DELTA-GRIP and DELT A LINER, as contrasted to appellee's use of DELTA alone. Appellant further contends that the two marks in issue are not arbitrary as the board found DELTA alone to be, but are suggestive, respectively, of a good grip in the drill block and of a bushing-liner.


9
We do not agree with appellant's contention and think the board was correct in its analysis in finding the marks substantially similar. Additionally, the GRIP and LINER portion of appellant's marks are, as a matter of degree, more descriptive than suggestive. In our view, this lends a high degree of dominance to the DELTA or DELT A portion of the mark, which in its pronunciation and arbitrary meaning, to a purchaser, is the same as appellee's mark DELTA.


10
It is fundamental, however, that identity or similarity of the marks alone is not enough to be conclusive of a likelihood of confusion. We must also consider the nature of the goods and the mark as applied thereto, the channels of trade, the class of purchasers, and other showings, such as, but not exclusively limited thereto, third party registrations, and absence of actual confusion.


11
Appellee contends that there is a relationship between the products of the parties. Appellant contends that the goods are in entirely different categories, it being necessary for skilled mechanics to specially mount the bushings in a block before they can be used. In answering that contention the board described the relationship of the goods as follows:


12
"* * * Applicant's [appellant's] goods are drill bushings, the sole function of which is to guide and increase the accuracy of drills of the type to which opposer applies its mark. * * *"


13
The point of that relationship as relating to likelihood of confusion is that one using a DELTA drill press may guide a DELTA drill through a DELTA-GRIP bushing or DELT A LINER bushing liner. That product relationship is such that it seems likely that a purchaser would think there is some connection between the producers of the various goods, and assume the quality of one carried over to the other.


14
As to the channels of trade, appellee points to a list of 22 dealers which handle goods of both parties. Appellee also points to the fact that the goods of both parties are advertised not only in the same type of media, but also calls our attention to over 60 instances in which the ads for the goods of both parties appeared in the same issue of the same publication. Appellant's response is twofold. First, appellant contends that there have been no instances of confusion, and second, since the goods are sold to strict specifications and the users are large manufacturing enterprises, those purchasers and the mill supply houses which do handle both goods are discriminating purchasers.


15
The board agreed with appellant that the purchasers of the goods of both parties would be discriminating purchasers, but did not find that fact to be sufficient to preclude the likelihood of confusion even among such purchasers. We think the board was correct. As this court stated in Wincharger Corp. v. Rinco, Inc., 297 F.2d 261, 49 CCPA 849:


16
"It is true that in most instances technicians would use the products of either party and they are a discriminating group of people but that does not eliminate the likelihood of purchaser confusion here. Being skilled in their own art does not necessarily preclude their mistaking one trademark for another when the marks are as similar as those here in issue, and cover merchandise in the same general field."


17
Appellant has presented an affidavit of Bethke, its Vice President in Charge of Sales, who after giving his background of extensive contact with dealers and buyers stated therein:


18
"He has found no instance of any kind, nature, or description since his employment by applicant where there has been any confusion between applicant's goods and opposer's goods."


19
An absence of proof of actual confusion is to be accorded some weight, Coral Chemical Co. v. H. D. T. Company Factors, Inc., 332 F.2d 841, 51 CCPA 1413. But, while we accord the affidavit a weight appropriate to the amount of evidence of "an absence of proof of actual confusion" that it represents, it does not convince us that there is no likelihood of confusion here. In any event, an absence of actual confusion is not conclusive on the issue of likelihood of confusion, Kautenberg Co. v. Ekco Products, 251 F.2d 628, 45 CCPA 761.


20
We have considered appellant's final contention that neither party has an intent of entering the other's field, but do not find that persuasive in view of the broad degree of protection to be accorded to appellee's arbitrary mark. Kautenberg Co. v. Ekco Products, supra. Further, a reasonable expansion of appellee's business to the goods of appellant should not be precluded. Magnavox Co. v. Multivox Corp. of America, 341 F.2d 139, 52 CCPA ___; Kautenberg Co. v. Ekco Products, supra.


21
We feel the conclusion inescapable; the type of purchasers here would be reasonably likely to assume that the products of the parties have a common origin or that they are in some way connected with each other. This to us spells a likelihood of confusion. The board did not err in sustaining the opposition.


22
Affirmed.
