1207.01(d)(vii)    Sophisticated Purchasers

The fact that purchasers are sophisticated or knowledgeable in a particular field does not necessarily mean that they are immune to source confusion. See In re Charger Ventures LLC, 64 F.4th 1375, 1383, 2023 USPQ2d 451, at *6 (Fed. Cir. 2023) (citing In re Rsch. & Trading Corp., 793 F.2d 1276, 1279, 230 USPQ 49, 50 (Fed. Cir. 1986) ("As the Board explained, careful or sophisticated consumers are not immune from source confusion.")); In re Shell Oil Co., 992 F.2d 1204, 1208, 26 USPQ2d 1687, 1690 (Fed. Cir. 1993) ("even sophisticated purchasers can be confused by very similar marks"); Weiss Assocs. v. HRL Assocs., 902 F.2d 1546, 1548, 14 USPQ2d 1840, 1841-42 (Fed. Cir. 1990) (similarities of goods and marks outweighed sophisticated purchasers, careful purchasing decision, and expensive goods); In re Info. Builders Inc., 2020 USPQ2d 10444, at *4 (TTAB 2020) (quoting In re Rsch. & Trading Corp., 793 F.2d at 1279, 230 USPQ at 50) ("That the relevant class of buyers may exercise care does not necessarily impose on that class the responsibility of distinguishing between similar trademarks for similar goods [or services]. ‘Human memories even of discriminating purchasers . . . are not infallible.’"); Top Tobacco, LP v. N. Atl. Operating Co., 101 USPQ2d 1163, 1170 (TTAB 2011) (citing In re Wilson, 57 USPQ2d 1863, 1865-66 (TTAB 2001); In re Decombe, 9 USPQ2d 1812, 1814-15 (TTAB 1988)) ("even consumers who exercise a higher degree of care are not necessarily knowledgeable regarding the trademarks at issue, and therefore immune from source confusion"); cf. Stone Lion Cap. Partners, L.P. v. Lion Cap. LLP, 746 F.3d 1317, 1325, 110 USPQ2d 1157, 1163 (Fed. Cir. 2014) (affirming that TTAB properly considered all potential investors for recited services, which included sophisticated investors, but that precedent required TTAB decision to be based "on the least sophisticated potential purchasers"). However, circumstances suggesting care in purchasing may tend to minimize the likelihood of confusion. See, e.g., In re N.A.D., Inc., 754 F.2d 996, 999-1000, 224 USPQ 969, 971 (Fed. Cir. 1985) (concluding that, because only sophisticated purchasers exercising great care would purchase the relevant goods, there would be no likelihood of confusion merely because of the similarity between the marks NARCO and NARKOMED); Primrose Ret. Cmtys., LLC v. Edward Rose Senior Living, LLC, 122 USPQ2d 1030, 1039 (TTAB 2016) ("even in the case of the least sophisticated purchaser, a decision as important as choosing a senior living community will be made with some thought and research, even when made hastily").
