I am looking for a court case that happened from 1899 to May of 1900. Samuel F. O'Reilly VS. Elmer E. Getchell. Not really sure how to go about this and any help would be greatly appreciated.

Me and a co-worker are working on documentation of ealy tattoo history and patents, I have became aware of a dispute between Sam O'Reilly (credited with the first tattoo machine patent) and a man named Elmer Getchell. I would like to obtain the court records but have no clue how to go about finding the case number, the county it was in and so on requierd to purchase the documents. Any help in how to go about obtaining this information will be greatly appreciated.
