The National Grange is suing an Oregon-based business called “The Hemp Grange,’’ alleging unauthorized use of its federally-registered trademark name.

The National Grange, formerly known as The National Grange of the Order of Patrons of Husbandry, was founded in 1867 to promote the interests of farmers and farming in the United States and has a network of more than 2,000 local chapters in the country.

It contends the hemp marketing and retail business in Oregon called “The Hemp Grange,’’ is unfairly benefiting from the National Grange’s reputation and is harming the national Grange reputation suggesting the two businesses are somehow related.

“Defendants’ use of the name and mark ‘The Hemp Grange’ with goods and services related to those offered by the Grange is therefore likely to cause confusion, mistake, or deception as to the affiliation, connection, or association of the ‘The Hemp Grange’ with the Grange, or as to the origin, sponsorship, or approval of Defendants’ goods and services by the Grange,’’ the suit says.

The Hemp Grange, according to its website, is a CBD manufacturer and retailer ”specializing in the extraction of high-quality CBD and sale of cannabis products.”

The suit, filed in federal court in Medford, alleges trademark infringement and seeks a court order barring “The Hemp Grange,’’ from using “Grange” in its name , and requiring the Oregon business to destroy its business cards and advertisements and cancel registration for the internet domain name thehempgrange.com.

Messages left for Thomas Dubiel at “TheHempGrange,’’ in Grants Pass were not immediately returned Monday.

Attorneys for the National Grange became aware of the Oregon business earlier this year after it had registered its website domain name: thehempgrange.com. National Grange lawyers attempted to contact Dubiel by mail and by phone.

In a March phone call, Dubiel and another man reached at “The Hemp Grange,’’ by lawyers for the plaintiffs claimed that their use of the name didn’t violate the National Grange’s trademark rights and “invited the Grange to bring a lawsuit,’’ according to the suit now filed.
