 American Piano Co. filed suit over the use of the name but the resulting injunction only prevented Knabe Brothers from using their original nameboard label, and required the brothers to indicate this was a new company.The plant burned in January 1912, but they quickly resumed production at a temporary factory before building a modern factory on the old site.The company went into receivership late in 1916 on account of an unpaid loan, and the brothers declared bankruptcy by the end of the year.
