Gedeon Richter Plc v Bayer Schering Pharma AG

Gedeon Richter Plc v Bayer Schering Pharma AG

Claims limited by the Paddle dissolution test (claim 1 of 301 and claim 6 of 069) are not invalid for obviousness over Oelkers or Lachnit, as the skilled formulator would not obviously proceed with an immediate release formulation given the acid lability of DSP. Claims 1 and 19 of 069 (not limited by the Paddle test) lack inventive step and are invalid for obviousness. Added matter objections fail except for the 3mg loading point, which is addressed by amendment.

Ratio Decidendi

Claims limited by the Paddle dissolution test (claim 1 of 301 and claim 6 of 069) are not invalid for obviousness over Oelkers or Lachnit, as the skilled formulator would not obviously proceed with an immediate release formulation given the acid lability of DSP. Claims 1 and 19 of 069 (not limited by the Paddle test) lack inventive step and are invalid for obviousness. Added matter objections fail except for the 3mg loading point, which is addressed by amendment.

Court Disposition

Partial revocation and amendment

Orders

  • 301 patent to be amended to address the 3mg loading point
