Procedural Posture

Civil Appeal (patent Infringement and Validity) / Hearing and Judgment in the Court of Appeal Arising From Hc/s 26/2016

Legal Issues

  1. 1 Construction of Claim 1 of Singapore Patent No 115872 (particularly limbs ii and iii) including the definition of 'first order' and measurement parameters
  2. 2 Validity of SG 872 (novelty, inventive step, sufficiency/enabling disclosure) and whether it should be revoked
  3. 3 Whether the accused samples infringe Claims 1ii, 1iii, 57, 58 and 62 of SG 872

Ratio Decidendi

The court focused on the proper construction of Claim 1 (notably limbs ii and iii) and the defined term 'first order' as specified in the patent; validity analysis turns on whether the specification and common general knowledge enable the production of single crystal CVD diamonds that meet the quantitative optical parameters in Claim 1 and whether the accused products fall within those construed parameters.
