The RUPTO’s Chamber for Patent Disputes rejected an opposition action against granting legal protection to the trademark ЭФФЕКС EFFEX owned by Sojuzpatent's client – CJSC “Evalar”, a major Russian producer of natural substances. Sojuzpatent team’s arguments prevailed as the Chamber for Patent Disputes disagreed with the opponent and confirmed compliance of the registration with Clause 6 of Article 1483 of the Civil Code of the Russian Federation. Thus, ЭФФЕКС EFFEX trademark registration under certificate No. 505620 remains in effect.
