Case: Asahi Kasei Kogyo KK's Application [1991] RPC 485 
Outcome: distinguished
Counsel for Sanofi-Aventis submitted that enabling disclosure, not mere disclosure, is required for anticipation, citing, most recently, Lindgren J in Alphapharm Pty Ltd [2008] FCA 559 at [160] [161] and the decision of the House of Lords in SmithKline Beecham (Paroxetine Methanesulfonate) Patent [2006] RPC 323. By way of introduction, it is worth remarking that the phrase "enabling disclosure" was brought to prominence by the speech of Lord Hoffmann in Biogen Inc v Medeva plc [1996] UKHL 18 ; [1997] RPC 1 , (1996) 36 IPR 438. That decision concerned the requirements for a valid patent under the 1997 United Kingdom Act (based upon the European Patent Convention) but did not concern the question of anticipation. The most important question was whether a later patent could claim an earlier priority date because it was "supported" by the earlier specification. That is a concept similar to, but narrower than, whether a later patent is fairly based upon an earlier specification in our law (cf F Hoffman-La Roche &amp; Co AG v Commissioner of Patents [1971] HCA 3 ; (1971) 123 CLR 529 ; CCOM Pty Ltd v Jiejing Pty Ltd [1994] FCA 1168 ; (1994) 51 FCR 260 ; Lockwood Security Products Pty Ltd v Doric Products Pty Ltd [2004] HCA 58 ; (2004) 217 CLR 274). It may be accepted that, in the case of a claim for a chemical compound by formula, in order to be valid, the specification would have to disclose how it might be manufactured (s 40). The phrase was also used in the speech of Lord Oliver in Asahi Kasei Kogyo KK's Application [1991] RPC 485 , to which I shall return. The phrase is reasonable shorthand in relation to the disclosure required for there to be anticipation of a process or method claim but, in my opinion, has little, if any, relevance to anticipation of a product claim or a claim for a chemical compound by formula. Indeed, it is apt to mislead in relation to the latter. For a product claim, the novelty must lie in the product not the means of producing it ( May &amp; Baker Ltd v Boots Pure Drug Co Ltd (1948) 65 RPC 255 at 281 282). By the same token, a new process to obtain an old product will have novelty. 56 Asahi Kasei Kogyo KK's Application [1991] RPC 485 concerned the 1977 United Kingdom Act. Counsel for the Comptroller of Patents neatly, and, in my opinion correctly, summed up the law as it previously stood in the following way ([1991] RPC at 520): "Novelty is a fundamental of patent law. Prior to the Act of 1977 it was settled law in the U.K. that "if the prior inventor's publication contains a clear description of, or clear instruction to do or make, something that would infringe that patentee's claim if carried out after the grant of the patentee's patent, that patentee's claim will have been shown to lack the necessary novelty", see: General Tire v. Firestone [1972] R.P.C. 457 at p 485. Accordingly under the Act of 1949 a claim to a chemical compound has been held to be anticipated by a statement that it has been prepared (Gyogyszeripari [1958] R.P.C. 51) or with a method for preparation which does not work (SKF [1968] R.P.C. 415). The latter cases were consistent with General Tire being instances where the prior documentation contained a description of the invention." The House of Lords upheld the contrary view of Falconer J in Re Genentech Inc's (Human Growth Hormone) Patent [1989] RPC 613. The 1977 Act, in s 2(2), included the words "made available to the public". Counsel in Asahi [1991] RPC 485 suggested this may have made a difference to the test. Falconer J's reasoning did not appear to depend upon that distinction, although he did refer to a decision of the Technical Board of Appeal of the European Patent Office supporting his position. Falconer J expressly declined to follow decisions of the Patents Appeal Tribunal in Gyogyszeripara Kurato Interzet's Application [1958] RPC 51 and Smith Kline &amp; French Laboratories' Application [1968] RPC 415 and the established practice of the Comptroller. Counsel for the petitioner for revocation in that case submitted that this was a departure from the long standing law in the United Kingdom as to anticipation and I agree with that submission.
