On February 27, 2007, the Chamber for Patent Disputes invalidated the Russian invention patent 2272319 in an opposition case filed by Sojuzpatent's patent attorneys on behalf of our client -“Kostroma Motor Plant”. It is interesting to note that this patent was used by the patent owner as a ground for criminal infringement accusations against several large Russian and Foreign companies. The companies' executives were criminally accused by patent owner for willingful infringement of the patent 2272319 on a large scale (article 147 of the Russian Criminal Code) and faced up to 5 years of imprisonment.
