The Wisconsin Cheesemaker Who Accidentally Cornered the Market on the Word 'Cheese'
The Paperwork That Broke an Industry
In the spring of 1909, Herman Klostermann thought he was just protecting his small Wisconsin creamery. The German immigrant had built a modest cheese-making operation in Green County, and with competition heating up, he decided to trademark his business name: "Klostermann's Superior Cheese Company."
What happened next would make legal scholars shake their heads for generations.
Due to a perfect storm of clerical errors, bureaucratic assumptions, and spectacularly poor record-keeping, Klostermann's trademark application was processed in a way that gave him broad protection over the word "cheese" itself on commercial food labels. Not just his specific brand name—the actual word.
When Bureaucracy Goes Haywire
The trouble started in the U.S. Patent Office, where an overworked clerk misread Klostermann's application. Instead of registering "Klostermann's Superior Cheese Company" as a business name, the clerk interpreted it as a claim for exclusive use of "Superior Cheese" as a product category.
But the real disaster came during the approval process. A supervising examiner, rushing through a backlog of applications, made a fateful assumption: if Klostermann was claiming "Superior Cheese," surely he meant to protect the core word "cheese" from competitors trying to ride his coattails.
In a decision that would haunt the dairy industry, the examiner approved what he believed was a reasonable request to prevent other companies from using "cheese" in their product names within Klostermann's market territory.
The Reckoning Begins
For months, nobody noticed the error. Klostermann continued making cheese, blissfully unaware that he now held legal ammunition against every dairy operation in Wisconsin. The bombshell dropped in early 1910, when a competitor received a cease-and-desist letter from Klostermann's lawyer—a document that cited the trademark registration and demanded they stop using "cheese" on their labels.
The competitor's attorney initially laughed it off. Then he looked up the registration.
"I stared at that document for twenty minutes," lawyer James Morrison later wrote in his memoirs. "I kept thinking there had to be some mistake, some fine print I was missing. But there it was, clear as day: Herman Klostermann owned the commercial rights to the word 'cheese' in our region."
The Great Cheese Name Crisis
As word spread through Wisconsin's dairy community, panic set in. Established cheese companies faced an impossible choice: pay licensing fees to Klostermann, rebrand their entire product lines, or fight a legal battle against what appeared to be an ironclad trademark.
Most chose the middle path, leading to one of the strangest periods in American food marketing history.
Suddenly, Wisconsin stores were filled with "Aged Dairy Wheels," "Cultured Milk Solids," and "Traditional Curd Blocks." The Sheboygan County Cooperative began marketing their cheddar as "Golden Pressed Cow Product." One desperate company tried "Solidified Cream Rectangles" before giving up entirely.
The Federal Government Gets Involved
By 1912, the absurdity had reached Washington. Dairy cooperatives were filing complaints with multiple federal agencies, arguing that one man's accidental monopoly on a basic food term was damaging interstate commerce.
The case landed on the desk of Judge William Patterson, who later described it as "the most peculiar legal situation of my career." Patterson found himself in the bizarre position of determining whether the English language itself could be owned by a single businessman.
"We had established legal precedent that trademarks protect specific brand names and logos," Patterson wrote in his decision. "But we had never contemplated what happens when bureaucratic error grants someone ownership of a word that predates commerce itself."
The Resolution Nobody Saw Coming
The breakthrough came from an unexpected source: Klostermann himself. As the legal battles intensified and public pressure mounted, the modest cheesemaker began to understand the full scope of what had happened.
In a move that surprised everyone, Klostermann voluntarily surrendered his trademark in 1918, issuing a public statement that he "never intended to own the English language, just protect my family business."
The Patent Office, thoroughly embarrassed by the decade-long fiasco, quietly implemented new review procedures to prevent similar disasters. But the damage was done—Wisconsin's dairy industry had spent nearly ten years navigating the legal minefield created by a single misfiled form.
The Legacy of Linguistic Chaos
Today, legal scholars still study the "Klostermann Case" as a cautionary tale about bureaucratic oversight and the unintended consequences of trademark law. Some of the alternative product names created during the crisis—like "Wisconsin Curd Wheels"—actually became popular marketing terms that survived long after the legal dispute ended.
As for Herman Klostermann, he continued making cheese under his original business name until his death in 1934. His tombstone in Green County bears a simple inscription: "He Made Good Cheese."
No mention of the word he accidentally owned.
