Leupold Drops Suit Against Zeiss

Portland, Oregon – Leupold & Stevens, Inc. 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 RangeĀ® (TBRĀ®) 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, they do not infringe on US Patent Number 7,654,029 owned by Leupold & Stevens, Inc.

Leupold & Stevens is a fifth-generation, family-owned company that employs over 600 American workers in its state-of-the-art facility near Beaverton, Ore. Leupold has manufactured a variety of optical and surveying instruments since opening for business in 1907, and its modern campus is currently where sport optics are designed, machined and assembled. Leupold manufactures a wide range of optics for the hunting and shooting, military and law enforcement, golf and observation markets.
