Patent in UK Law

Leading Cases
  • Synthon BV v Smithkline Beecham Plc (No.2)
    • House of Lords
    • 20 Oct 2005

    If I may summarise the effect of these two well-known statements, the matter relied upon as prior art must disclose subject-matter which, if performed, would necessarily result in an infringement of the patent. That may be because the prior art discloses the same invention. In that case there will be no question that performance of the earlier invention would infringe and usually it will be apparent to someone who is aware of both the prior art and the patent that it will do so.

  • Mölnlycke A.B. v Procter & Gamble Ltd
    • Court of Appeal
    • 27 Jun 1991

    Conversely the English court could not entertain a claim for the infringement of a German patent. English patent law as embodied in the Patents Act 1977 is founded on international convention, not just European Community convention, but, subject to certain special provisions of the Act, its application by the English court is a matter of English law.

  • Seager v Copydex Ltd
    • Court of Appeal
    • 18 Apr 1967

    It depends on the broad principle of equity that he who has received information in confidence shall not take unfair advantage of it. He must not make use of it to the prejudice of him who gave it without obtaining his consent. He should go to the public source and get it: or, at any rate, not be in a better position than if he had gone to the public source. He should not get a start over others by using the information which he received in confidence.

  • Angiotech Pharmaceuticals Inc. v Conor Medsystems Inc.
    • House of Lords
    • 09 Jul 2008

    In the Court of Appeal, Jacob LJ dealt comprehensively with the question of when an invention could be considered obvious on the ground that it was obvious to try. He correctly summarised the authorities, starting with the judgment of Diplock LJ in Johns-Manville Corporation's Patent [1967] RPC 479, by saying that the notion of something being obvious to try was useful only in a case in which there was a fair expectation of success.

  • Biogen Inc. v Medeva Plc
    • House of Lords
    • 31 Oct 1996

    His expressed findings are always surrounded by a penumbra of imprecision as to emphasis, relative weight, minor qualification and nuance ( as Renan said, la v�rit� est dans une nuance), of which time and language do not permit exact expression, but which may play an important part in the judge's overall evaluation.

  • Windsurfing International Inc. v Tabur Marine (Great Britain) Ltd
    • Court of Appeal
    • 31 Jan 1984

    Thereafter, the court has to assume the mantle of the normally skilled but unimaginative addressee in the art at the priority date and to impute to him what was, at that date, common general knowledge in the art in question. Finally, the court has to ask itself whether, viewed without any knowledge of the alleged invention, those differences constitute steps which would have been obvious to the skilled man or whether they require any degree of invention.

  • Generics (UK) Ltd v H Lundbeck A/S
    • Chancery Division (Patents Court)
    • 04 May 2007

    Paragraph [45] is, to my mind, key. The question of obviousness must be considered on the facts of each case. The court must consider the weight to be attached to any particular factor in the light of all the relevant circumstances. These may include such matters as the motive to find a solution to the problem the patent addresses, the number and extent of the possible avenues of research, the effort involved in pursuing them and the expectation of success.
