Citing what he called a “coordinated harassment campaign,” Stone Brewing co-founder Greg Koch took to his brewery’s blog earlier this week to address a trademark dispute with Morehead, Kentucky-based Sawstone Brewing.

“Over the last week or so, much ado has been made over our attempt to protect our name, Stone Brewing Co., and our registered trademarks,” Koch wrote. “And this ‘much ado’ involved a lot of vociferous accusations and name calling.”

Stone filed a petition for the cancellation of Sawstone’s trademark application on March 10 on the grounds that there was “likelihood of confusion” among consumers due to Sawstone’s name, which could cause “dilution by blurring.” According to Koch, attorneys for both breweries discussed “settlement possibilities” on May 22, but lawyers for Local Pioneers, the parent company of Sawstone, did not send a proposal.

As weeks passed with no proposal, Stone’s attorneys filed a motion to compel Sawstone to provide initial disclosures on July 8. The next week, on July 17, Sawstone’s attorneys told Stone that they would send the proposal the following week, but then the situation changed, Koch wrote.

“Out of the clear blue, we became the subject of a vicious online harassment and smear campaign — one that was so far removed from the facts of what had actually happened that it even falsely accused us of having sent more than a hundred cease-and-desist letters this year,” he added. “This campaign also included cyber- and cell phone stalking and harassment, complete with personal threats to me and employees.”
