Okla. Stat. tit. 12A, § 2-315
Oklahoma Code Comment
Oklahoma has previously applied the warranty of fitness for a particular purpose in many cases, using the Uniform Sales Act definition, although Oklahoma did not have that act. This required the buyer to "inform" the seller of his needs. Eden v. Vloedman, 202 Okl. 462, 214 P.2d 930 (1949); Balch Newberry, 208 Okl. 46, 253 P.2d 153, 35 A. L.R.2d 1267 (1953); Fairbanks, Morse & Co. v. Miller, 80 Okl. 265, 195 P. 1083 (1921); Chicago Steel Foundry Co. v. F. M. Crowell Co., 159 Okl. 211, 14 P.2d 1105 (1932)
Oklahoma has previously held that one who purchased by trade-name could not rely upon the warranty, but they are cases in which the evidence is quite clear that the buyer in fact relied upon his own judgment, and not that of the seller. Obenchain & Boyer v. Incorporated Town of Roff, 29 Okl. 211, 116 P. 782 (1911); Smith v. Continental Supply Co., 118 Okl. 287 248 P. 626, 59 A.L.R. 1536 (1926).
