Smithkline Beecham Plc & Ors. v Apotex Europe Ltd & Ors [2004] EWCA Civ 1568 (29 November 2004)

Smithkline Beecham Plc & Ors. v Apotex Europe Ltd & Ors [2004] EWCA Civ 1568 (29 November 2004)

The Court of Appeal held that the patent claims were not anticipated by the '407 patent because the prior art did not provide clear and unambiguous instructions that would inevitably result in the claimed invention, nor would the skilled person, without hindsight, understand the water slurry step as a displacement of solvent. The claims were also not obvious because the modifications required to achieve the claimed invention from the prior art were not obvious to the skilled person. The trial judge erred in principle by failing to read the prior art in the context of the whole disclosure and with the mind of the skilled person.

Procedural Posture

Patent Infringement and Revocation Appeal / Appeal From High Court (patents Court) to Court of Appeal

Legal Issues

  1. 1 Whether the patent claims are anticipated by prior art ('407 patent)
  2. 2 Whether the patent claims are obvious in light of prior art
  3. 3 Proper construction of the patent claims

Ratio Decidendi

The Court of Appeal held that the patent claims were not anticipated by the '407 patent because the prior art did not provide clear and unambiguous instructions that would inevitably result in the claimed invention, nor would the skilled person, without hindsight, understand the water slurry step as a displacement of solvent. The claims were also not obvious because the modifications required to achieve the claimed invention from the prior art were not obvious to the skilled person. The trial judge erred in principle by failing to read the prior art in the context of the whole disclosure and with the mind of the skilled person.

Court Disposition

Appeal allowed; patent held valid and not anticipated or obvious over the prior art.

Orders

  • Order for revocation of the patent set aside.
  • Patent claims 1 and 2 held valid.
