Patent Infringement in UK Law

Leading Cases
  • Mölnlycke A.B. v Procter & Gamble Ltd
    • Court of Appeal (Civil Division)
    • 27 June 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.

  • Synthon BV v Smithkline Beecham Plc (No.2)
    • House of Lords
    • 20 October 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.

  • Kirin-Amgen v Hoechst Marion Roussel Ltd
    • House of Lords
    • 21 October 2004

    The question is always what the person skilled in the art would have understood the patentee to be using the language of the claim to mean. And for this purpose, the language he has chosen is usually of critical importance. On the other hand, it must be recognised that the patentee is trying to describe something which, at any rate in his opinion, is new; which has not existed before and of which there may be no generally accepted definition.

  • Actavis UK Ltd and Others v Eli Lilly and Company
    • Supreme Court
    • 12 July 2017

    Secondly, the fact that the language of the claim does not on any sensible reading cover the variant is certainly not enough to justify holding that the patentee does not satisfy the third question. Thirdly, when considering the third question, it is appropriate to ask whether the component at issue is an "essential" part of the invention, but that is not the same thing as asking if it is an "essential" part of the overall product or process of which the inventive concept is part.

  • Catnic Components Ltd and Another v Hill and Smith Ltd
    • House of Lords
    • 1980

    A patent specification should be given a purposive construction rather than a purely literal one derived from applying to it the kind of meticulous verbal analysis in which lawyers are too often tempted by their training to indulge.

  • Virgin Atlantic Airways Ltd v Zodiac Seats UK Ltd (formerly known as Contour Aerospace Ltd)
    • Supreme Court
    • 03 July 2013

    A decision of an English court declaring a patent invalid, or (which will normally follow) revoking it, will have effect in the United Kingdom only, whereas a corresponding decision of the EPO, which was the authority by which the patent was granted, will have effect in all the states for which the patent was granted.

  • Glaxo Group Ltd v Genentech Inc.
    • Court of Appeal (Civil Division)
    • 31 January 2008

    Fourthly, the possibility of the duplication of proceedings contesting the validity of a patent granted by the EPO is inherent in the system established by the EPC. In practice national courts exercise exclusive jurisdiction on infringement issues and they have concurrent jurisdiction with the EPO on validity issues.
