Hey Guys it would seam there is a lot of talk about other individuals making a braking system even one manufactured for sale but in order to dispute a patent i am sure in court this would need proof provided pictures dates on product offering ETC.
With BVM patent does it apply to any type of brake with an expansion o'ring or tubing there is so much legal verbiage it's hard to decipher what is actually claimed any legal type's out there understand what is stated in the patent?
