  Before MARTIN, Chief Justice, ROBB, Associate Justice, and SMITH, Judge of the United States Court of Customs Appeals.
  ROBB, Associate Justice.
  Appeal from a decision of an Assistant Commissioner of Patents in a trade-mark opposition proceeding, in which the decision of the Examiner of Interferences was reversed and the opposition dismissed.
  The opposer, appellant here, and its predecessor, long prior to the adoption in 1921 by the applicant, appellee here, of the trade-mark “Pappoose” for use on salt, had built up a very extensive business under the same' mark in connection with the sale of .various condiments, including pepper sauce, table sauce, mustard, tomato catsup, cayenne .pepper, whole and ground pepper, and the like.
  The Examiner of Interferences found that salt belongs to that class known generally as condiments; that “it is merely one of a group including pepper, mustard, and spices, which are used for seasoning food.” With that postulate, his decision, of course, was against the right of registration by the newcomer. The decisions of this court, upon which he relied, fully sustain his ruling. See Walter Baker & Co. v. Harrison, 32 App. D. C. 272; Simplex Elec. H. Co. v. Gold Car H. & L. Co., 43 App. D. C. 28; Anglo-American I. L. Co. v. Gen. Elec. Co., 43 App. D. C. 385; Fishbeck Soap Co. v. Kleeno Mfg. Co., 44 App. D. C. 6; Canton Culvert & Silo Co. v. Consol. Car-Heat. Co., 44 App. D. C. 491; Gutta-Percha & Rubber Mfg. Co. v. Ajax Mfg. Co., 48 App. D. C. 230; Macy & Co. v. N. Y. Grocery Co., 50 App. D. C. 105, 267 F. 749; Cal. Pkg. Corp. v. Price-Booker Mfg. Co., 52 App. D. C. 259, 285 F. 993; Cal. Pkg. Corp. v. Halferty, 54 App. D. C. 88, 295 F. 229.
  The wide reputation established by the opposer furnishes the only apparent excuse for the adoption of this mark by the applicant. Decision reversed.
  Reversed.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "trade". Your task is to determine what subcategory of business best describes this litigant.
