«A.Zalesov & Partners» filed an invalidation action against patent RU 2412073 basing on three grounds: lack of industrial applicability, lack of novelty and lack on inventive step. Although the grounds may seem to be controversial, this controversy was caused by highly unclear terms in patent claims. Therefore depending on claims construction, «A.Zalesov & Partners» claimed that the patent should either lack industrial applicability, or novelty, or inventive step. During the hearings on March 06, 2018 the Chamber for Patent Disputes announced the patent fully invalid due to the lack of industrial applicability.
