Larry L. Williams sued Dougherty Forestry Manufacturing, Ltd. on Friday over allegations that the company developed and sold products in violation of his patent.
Williams sells tree cutting equipment of his own design to forestry companies. He received a patent for his design for tree cutting attachments that connect to a skid steer loader in May 2012.
Dougherty Forestry Manufacturing creates and markets several forestry products. The majority of its equipment is marketed under the Turbo Saw brand.
Williams alleged in the suit that Dougherty has repeatedly, willfully and deliberately infringed on his rights. He cited the company's brush and tree cutting equipment marketed as FIXED BROOM under its Turbo Saw label.
Williams claimed that Dougherty Forestry Manufacturing shows no signs of stopping their infringement.
Williams further alleges that these infringements have harmed and will continue to harm him and his company, saying he has lost customers, profits and sales for his designs. These continued losses have grown to such an extent that he doubts his business will ever recover.
Williams is seeking an injunction against Dougherty to stop infringing on his patent rights, as well as repayment for lost business.
Williams is being represented by Daniel P. Dooley from Hall, Estill, Hardwick, Gable, Golden & Nelson in Oklahoma City.
