Double trouble.

The authors comment on how the Great Britain and European Patent Office (EPO) approaches to the issue of double patenting. It mentions that the British Patents Act 1977 has no specific rule that prevents the court to permit double patents for an invention, highlights EPO's practice that does not allow double patenting for European applicants with the same filing applicant and date, and discusses the European Patent Convention's (EPC) Article 60(1) on patent right for an invention.
