NoTubes.com is taking Specialized Bicycles to court over claims that some of the firm's Roval brand wheels infringe one of its patents.
New York-based NoTubes, best known for its Stan's tubeless kits, alleges that Specialized has infringed US patent 7,334,846 "by making, using, selling, offering for sale and/or importing into the United States certain tubeless wheels and rims".
The patent covers a rim design invented by NoTubes’ founder and owner, Stan Koziatek.
The lawsuit, filed under the name of NoTubes' parent company, KG Motors Inc, is pending in the United States District Court for the Western District of New York. Specialized officials have no comment on the pending suit.
