Leupold & Stevens, Inc. comfirmed in a release that it has dropped its lawsuit against Carl Zeiss Optical, Inc. for patent infringement. The lawsuit alleges that Zeiss and two other defendants infringe on a patent that Leupold & Stevens holds involving True Ballistic Range® (TBR®) technology.
While Zeiss products do allow users to input ballistic groups and display holdover values at specific yardages, it has been determined that they do not incorporate an inclinometer to compensate for uphill/downhill shot angles. Therefore, Leupold said they do not infringe on US Patent Number 7,654,029 owned by Leupold & Stevens, Inc.
