Stan’s NoTubes, the New York-based manufacturer of innovative rims, wheels and tubeless products, has ‘prevailed at the United States Court of Appeals for the Federal Circuit in a hard-fought battle against Specialized Bicycle Components.’

A release from Stan’s NoTubes notes that the Federal Circuit decision upholds a previous ruling by the Patent Trial and Appeal Board (PTAB), which had declared Stan’s NoTubes’ US Patent Number 7,334,846 to be valid.

“We are pleased to have reached a positive conclusion regarding our rim design patent. The court’s decision further strengthens our patent portfolio,” said Stan’s NoTubes co-owners Stan and Cindy Koziatek. “We look forward to continuing the advancement of tubeless wheels for all cycling applications.”

The Federal Circuit heard arguments from Stan’s NoTubes and Specialized on 2 February 2016. At oral argument, the Federal Circuit panel appeared to ‘credit evidence showing the industry’s rapid adoption of Stan’s ZTR rims and praise for their patented features and suggested that this objective evidence helps demonstrate that the claims of the ’846 patent are valid.’

An audio recording of the argument is available online.

On 4 February 2016, the Federal Circuit affirmed the PTAB’s decision in a Rule 36 summary affirmance.

Stan’s NoTubes notes that this matter began in 2008 when Specialized released rims that Stan’s NoTubes alleged to infringe the ’846 patent.

The company release continued, ‘Stan’s NoTubes was left with no choice but to protect its proprietary technology by suing to stop Specialized’s alleged infringement in the United States District Court for the Western District of New York. A judgment was entered against Specialized in that case in 2015, with Specialized paying compensation to Stan’s NoTubes.’

Stan’s NoTubes currently holds the following four US patents related to the rims and wheels in its ZTR family of products with Bead Socket Technology:

Stan’s NoTubes, founded and owned by Stan and Cindy Koziatek, helped to set the industry standard for making mountain bikes tyres tubeless. Using his ingenuity, Stan Koziatek devised the original NoTubes sealing system in 2001, the same system that today has become a preferred tubeless conversion system around the world.

Stan’s NoTubes currently designs, produces and sells mountain bike, road and cyclocross wheels, rims and hubs as well as a range of products for tubeless conversion.
