PPG Industries Chemicals B.V. v. Rhodia Chimi, District Court The Hague, The Netherlands, 4 December 2013, Case / Docket number C/09/437543 / HA ZA 13-190
Rhodia attempted to obtain a preliminary injunction against PPG on account of infringement of European patent no. 0 520 862 B1 (the “Patent”). In April 2012 Rhodia’s petition was denied for lack of an urgent interest. Following the preliminary injunction proceedings PPG initiated proceedings on the merits, demanding annulment of the Dutch part of the Patent.
The Patent relates to a new process for preparing precipitated silica, the new precipitated silicas thus obtained, and their use in the reinforcement of rubbers. Claims 1 through 12 relate to a method, product claims 13 through 21 to granules, product claims 22 through 27 to a powder and product claims 28 through 36 to substantially spherical beads. Claim 37 is a use claim.
