Bushnell Sues Leupold & Stevens for Patent Infringement

Bushnell Outdoor Products has sued Leupold & Stevens for infringing on two Bushnell U.S. Patents covering the Bushnell Angle Range Compensation™ (ARC™) and Rain™ Mode laser rangefinder technology. The lawsuit was filed in the United States District Court for the District of Kansas on February 9, 2010 and alleges that Leupold is infringing on Bushnell U.S. Patent Nos. 5,926,259 and 7,658,031.

Angle Range Compensation is important for both rifle shooters and bow-hunters. When a shooter or archer takes a shot at an extreme up or down angle, there will be less drop than with a non-angled shot (given the same line of sight distance to target). By fitting an inclinometer to its rangefinders, Bushnell is able to plot the shot angle and display the “effective ballistic distance” to the target. You can then quickly calculate the hold-over you actually need.

Bushnell pioneered the sportsman-oriented laser rangefinder, and Bushnell was selling rangefinders long before Leupold even entered the laser rangefinder market. Bushnell earned U.S. Patent No. 7,658,031 for its rangefinder technology that provides hold-over info for angled shots.

“Bushnell has invested an enormous amount of time and resources into developing our patented technology and we will vigorously enforce our rights against all infringers,” said Phil Gyori, Executive Vice President of Marketing at Bushnell Inc. “While we prefer to resolve disputes with our competitors without resorting to litigation, we felt we had no choice but to defend our intellectual property against Leupold’s infringement.”
