Smithkline Beecham Plc & Ors. v Apotex Europe Ltd & Ors

Smithkline Beecham Plc & Ors. v Apotex Europe Ltd & Ors

The patent was not anticipated or rendered obvious by the prior art because the skilled person would not, without hindsight, understand the prior art to disclose or make obvious the displacement step as claimed. The process used by Apotex did not infringe the patent as properly construed, since 'displacing agent' in the claims did not cover Apotex's acetone process, and the patent claims were not shown to be insufficient or ambiguous for the purposes of this appeal.

Procedural Posture

Civil Appeal (patent) / Appeal From High Court (patents Court) to Court of Appeal

Legal Issues

  1. 1 Whether UK Patent No. 2,297,550 is invalid for anticipation or obviousness over prior art ('407 and erythromycin patent)
  2. 2 Whether the process used by Apotex infringes the patent claims as construed
  3. 3 Proper construction of 'displacing agent' in the patent claims

Ratio Decidendi

The patent was not anticipated or rendered obvious by the prior art because the skilled person would not, without hindsight, understand the prior art to disclose or make obvious the displacement step as claimed. The process used by Apotex did not infringe the patent as properly construed, since 'displacing agent' in the claims did not cover Apotex's acetone process, and the patent claims were not shown to be insufficient or ambiguous for the purposes of this appeal.

Court Disposition

Appeal allowed in part; High Court's finding of invalidity reversed; finding of non-infringement upheld; patent to be restored to the register.

Orders

  • Patent not invalid for anticipation or obviousness over '407 or erythromycin patent.
