Wal-Mart is facing strong objections from some of its competitors over the retail giant’s attempt to trademark “EDLP”, meaning “Everyday Low Prices.”

Wal-Mart filed an application with the US Patent and Trademark office last summer to reserve the acronym and phrase for its own use, but the National Grocers Association (NGA) and Supervalu stores argue that use of the specific term is already widespread among retailers.

Supervalu said that it has used the term “everyday low prices” since 1984, and the NGA counters that the grocery and supermarket industry has been employing the acronym for more than 20 years, with many retailers using it both internally and externally in marketing materials to show that they offer low prices every day.

Food Lion, Associated Grocers, Unified Western Grocers and the National Association of Convenience Stores have also indicated they may officially oppose the application.
