Leupold Files Suit to Defend TBR Patent
BEAVERTON, Ore. - Leupold & Stevens, Inc. has sued Bushnell, Inc. and others for infringement of a patent granted to Leupold® relating to its True Ballistic Range® technology (TBR®).

With TBR, Leupold pioneered ballistic compensation for uphill/downhill shot angles, superseding basic trigonometric angle/distance compensation. TBR was introduced by Leupold in 2006, and uses an advanced algorithm to deliver exceptionally accurate ranging capability that is matched to a bullet's ballistic profile.

The complaint was filed February 2, 2010, in U.S. District Court in Portland, Ore., and alleges that Bushnell's sales of range-finding products incorporating Angle Range Compensation™ (ARC™) infringe U.S. Patent No. 7,654,029 owned by Leupold.

"Leupold asserted provisional patent rights more than two years before filing suit, but Bushnell continued to manufacture and sell the infringing products," said Andy York, Leupold's vice president of sales, marketing, and product development. "Leupold has invested a significant amount of engineering and development resources in the production of this patented technology and the company will vigorously enforce its intellectual property rights against all infringers. Generally, we prefer to resolve disputes without resorting to litigation, but in this case, our management decided that due to the substantial amount of time some of the defendants had been on notice, that litigation was necessary."

The complaint also names as defendants Burris Co, Inc. for the Burris Eliminator™ laser scope, and Carl Zeiss Optical, Inc. for sales of range-finding products incorporating its Ballistic Information System™ (BIS) feature.

Leupold® Drops Carl Zeiss Optical from Patent Infringement Lawsuit
Portland, OR--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 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, they do not infringe on US Patent Number 7,654,029 owned by Leupold & Stevens, Inc.
