(1)Subject to the provisions of this section, a person infringes a patent for an invention if, but only if, while the patent is in force, he does any of the following things in the United Kingdom in relation to the invention without the consent of the proprietor of the patent, that is to say—
(a)where the invention is a product, he makes, disposes of, offers to dispose of, uses or imports the product or keeps it whether for disposal or otherwise;
(b)where the invention is a process, he uses the process or he offers it for use in the United Kingdom when he knows, or it is obvious to a reasonable person in the circumstances, that its use there without the consent of the proprietor would be an infringement of the patent;
(c)where the invention is a process, he disposes of, offers to dispose of, uses or imports any product obtained directly by means of that process or keeps any such product whether for disposal or otherwise.
(2)Subject to the following provisions of this section, a person (other than the proprietor of the patent) also infringes a patent for an invention if, while the patent is in force and without the consent of the proprietor, he supplies or offers to supply in the United Kingdom a person other than a licensee or other person entitled to work the invention with any of the means, relating to an essential element of the invention, for putting the invention into effect when he knows, or it is obvious to a reasonable person in the circumstances, that those means are suitable for putting, and are intended to put, the invention into effect in the United Kingdom.
(3)Subsection (2) above shall not apply to the supply or offer of a staple commercial product unless the supply or the offer is made for the purpose of inducing the person supplied or, as the case may be, the person to whom the offer is made to do an act which constitutes an infringement of the patent by virtue of subsection (1) above.
(4)Without prejudice to section 86 below, subsections (1) and (2) above shall not apply to any act which, under any provision of the Community Patent Convention relating to the exhaustion of the rights of the proprietor of a patent, as that provision applies by virtue of that section, cannot be prevented by the proprietor of the patent.
(5)An act which, apart from this subsection, would constitute an infringement of a patent for an invention shall not do so if—
(a)it is done privately and for purposes which are not commercial;
(b)it is done for experimental purposes relating to the subject-matter of the invention;
(c)it consists of the extemporaneous preparation in a pharmacy of a medicine for an individual in accordance with a prescription given by a registered medical or dental practitioner or consists of dealing with a medicine so prepared;
(d)it consists of the use, exclusively for the needs of a relevant ship, of a product or process in the body of such a ship or in its machinery, tackle, apparatus or other accessories, in a case where the ship has temporarily or accidentally entered the internal or territorial waters of the United Kingdom;
(e)it consists of the use of a product or process in the body or operation of a relevant aircraft, hovercraft or vehicle which has temporarily or accidentally entered or is crossing the United Kingdom (including the air space above it and its territorial waters) or the use of accessories for such a relevant aircraft, hovercraft or vehicle;
(f)it consists of the use of an exempted aircraft which has lawfully entered or is lawfully crossing the United Kingdom as aforesaid or of the importation into the United Kingdom, or the use or storage there, of any part or accessory for such an aircraft.
(6)For the purposes of subsection (2) above a person who does an act in relation to an invention which is prevented only by virtue of paragraph (a), (b) or (c) of subsection (5) above from constituting an infringement of a patent for the invention shall not be treated as a person entitled to work the invention, but—
(a)the reference in that subsection to a person entitled to work an invention includes a reference to a person so entitled by virtue of section 55 above, and
(b)a person who by virtue of [F1section 28A(4) or (5)] above or section 64 below is entitled to do an act in relation to the invention without it constituting such an infringement shall, so far as concerns that act, be treated as a person entitled to work the invention.
(7)In this section—
“relevant ship” and “relevant aircraft, hovercraft or vehicle” mean respectively a ship and an aircraft, hovercraft or vehicle registered in, or belonging to, any country, other than the United Kingdom, which is a party to the Convention for the Protection of Industrial Property signed at Paris on 20th March 1883; and

(e)for a declaration or declarator that the patent is valid and has been infringed by him.
(2)The court shall not, in respect of the same infringement, both award the proprietor of a patent damages and order that he shall be given an account of the profits.
(3)The proprietor of a patent and any other person may by agreement with each other refer to the comptroller the question whether that other person has infringed the patent and on the reference the proprietor of the patent may make any claim mentioned in subsection (1)(c) or (e) above.
(4)Except so far as the context requires, in the following provisions of this Act—
(a)any reference to proceedings for infringement and the bringing of such proceedings includes a reference to a reference under subsection (3) above and the making of such a reference;
(b)any reference to a plaintiff or pursuer includes a reference to the proprietor of the patent; and
(c)any reference to a defendant or defender includes a reference to any other party to the reference.
(5)If it appears to the comptroller on a reference under subsection (3) above that the question referred to him would more properly be determined by the court, he may decline to deal with it and the court shall have jurisdiction to determine the question as if the reference were proceedings brought in the court.
(6)Subject to the following provisions of this Part of this Act, in determining whether or not to grant any kind of relief claimed under this section and the extent of the relief granted the court or the comptroller shall apply the principles applied by the court in relation to that kind of relief immediately before the appointed day.
(1)In proceedings for infringement of a patent damages shall not be awarded, and no order shall be made for an account of profits, against a defendant or defender who proves that at the date of the infringement he was not aware, and had no reasonable grounds for supposing, that the patent existed; and a person shall not be taken to have been so aware or to have had reasonable grounds for so supposing by reason only of the application to a product of the word “patent” or “patented”, or any word or words expressing or implying that a patent has been obtained for the product, unless the number of the patent accompanied the word or words in question.
(2)In proceedings for infringement of a patent the court or the comptroller may, if it or he thinks fit, refuse to award any damages or make any such order in respect of an infringement committed during any further period specified under section 25(4) above, but before the payment of the renewal fee and any additional fee prescribed for the purposes of that subsection.
(3)Where an amendment of the specification of a patent has been allowed under any of the provisions of this Act, no damages shall be awarded in proceedings for an infringement of the patent committed before the decision to allow the amendment unless the court or the comptroller is satisfied that the specification of the patent as published was framed in good faith and with reasonable skill and knowledge.
(1)If the validity of a patent is put in issue in proceedings for infringement of the patent and it is found that the patent is only partially valid, the court or the comptroller may, subject to subsection (2) below, grant relief in respect of that part of the patent which is found to be valid and infringed.
(2)Where in any such proceedings it is found that a patent is only partially valid, the court or the comptroller shall not grant relief by way of damages, costs or expenses, except where the plaintiff or pursuer proves that the specification for the patent was framed in good faith and with reasonable skill and knowledge, and in that event the court or the comptroller may grant relief in respect of that part of the patent which is valid and infringed, subject to the discretion of the court or the comptroller as to costs or expenses and as to the date from which damages should be reckoned.
(3)As a condition of relief under this section the court or the comptroller may direct that the specification of the patent shall be amended to its or his satisfaction upon an application made for that purpose under section 75 below, and an application may be so made accordingly, whether or not all other issues in the proceedings have been determined.
(1)Where a patent is granted for an invention, a person who in the United Kingdom before the priority date of the invention—
(a)does in good faith an act which would constitute an infringement of the patent if it were in force, or
(b)makes in good faith effective and serious preparations to do such an act,
has the right to continue to do the act or, as the case may be, to do the act, notwithstanding the grant of the patent; but this right does not extend to granting a licence to another person to do the act.
(2)If the act was done, or the preparations were made, in the course of a business, the person entitled to the right conferred by subsection (1) may—
(a)authorise the doing of that act by any partners of his for the time being in that business, and
(b)assign that right, or transmit it on death (or in the case of a body corporate on its dissolution), to any person who acquires that part of the business in the course of which the act was done or the preparations were made.
(3)Where a product is disposed of to another in exercise of the rights conferred by subsection (1) or (2), that other and any person claiming through him may deal with the product in the same way as if it had been disposed of by the registered proprietor of the patent.]

(1)If in any proceedings before the court or the comptroller the validity of a patent to any extent is contested and that patent is found by the court or the comptroller to be wholly or partially valid, the court or the comptroller may certify the finding and the fact that the validity of the patent was so contested.
(2)Where a certificate is granted under this section, then, if in any subsequent proceedings before the court or the comptroller for infringement of the patent concerned or for revocation of the patent a final order or judgment or interlocutor is made or given in favour of the party relying on the validity of the patent as found in the earlier proceedings, that party shall, unless the court or the comptroller otherwise directs, be entitled to his costs or expenses as between solicitor and own client (other than the costs or expenses of any appeal in the subsequent proceedings).
(1)In the application of section 60 above to a patent of which there are two or more joint proprietors the reference to the proprietor shall be construed—
(a)in relation to any act, as a reference to that proprietor or those proprietors who, by virtue of section 36 above or any agreement referred to in that section, is or are entitled to do that act without its amounting to an infringement; and
(b)in relation to any consent, as a reference to that proprietor or those proprietors who, by virtue of section 36 above or any such agreement, is or are the proper person or persons to give the requisite consent.
(2)One of two or more joint proprietors of a patent may without the concurrence of the others bring proceedings in respect of an act alleged to infringe the patent, but shall not do so unless the others are made parties to the proceedings; but any of the others made a defendant or defender shall not be liable for any costs or expenses unless he enters an appearance and takes part in the proceedings.
(1)Subject to the provisions of this section, the holder of an exclusive licence under a patent shall have the same right as the proprietor of the patent to bring proceedings in respect of any infringement of the patent committed after the date of the licence; and references to the proprietor of the patent in the provisions of this Act relating to infringement shall be construed accordingly.
(2)In awarding damages or granting any other relief in any such proceedings the court or the comptroller shall take into consideration any loss suffered or likely to be suffered by the exclusive licensee as such as a result of the infringement, or, as the case may be, the profits derived from the infringement, so far as it constitutes an infringement of the rights of the exclusive licensee as such.
(3)In any proceedings taken by an exclusive licensee by virtue of this section the proprietor of the patent shall be made a party to the proceedings, but if made a defendant or defender shall not be liable for any costs or expenses unless he enters an appearance and takes part in the proceedings.
Where by virtue of a transaction, instrument or event to which section 33 above applies a person becomes the proprietor or one of the proprietors or an exclusive licensee of a patent and the patent is subsequently infringed, the court or the comptroller shall not award him damages or order that he be given an account of the profits in respect of such a subsequent infringement occurring before the transaction, instrument or event is registered unless—
(a)the transaction, instrument or event is registered within the period of six months beginning with its date; or
(b)the court or the comptroller is satisfied that it was not practicable to register the transaction, instrument or event before the end of that period and that it was registered as soon as practicable thereafter.
(1)Where an application for a patent for an invention is published, then, subject to subsections (2) and (3) below, the applicant shall have, as from the publication and until the grant of the patent, the same right as he would have had, if the patent had been granted on the date of the publication of the application, to bring proceedings in the court or before the comptroller for damages in respect of any act which would have infringed the patent; and (subject to subsections (2) and (3) below) references in sections 60 to 62 and 66 to 68 above to a patent and the proprietor of a patent shall be respectively construed as including references to any such application and the applicant, and references to a patent being in force, being granted, being valid or existing shall be construed accordingly.
(2)The applicant shall be entitled to bring proceedings by virtue of this section in respect of any act only—
(a)after the patent has been granted; and
(b)if the act would, if the patent had been granted on the date of the publication of the application, have infringed not only the patent, but also the claims (as interpreted by the description and any drawings referred to in the description or claims) in the form in which they were contained in the application immediately before the preparations for its publication were completed by the Patent Office.
(3)Section 62(2) and (3) above shall not apply to an infringement of the rights conferred by this section, but in considering the amount of any damages for such an infringement, the court or the comptroller shall consider whether or not it would have been reasonable to expect, from a consideration of the application as published under section 16 above, that a patent would be granted conferring on the proprietor of the patent protection from an act of the same description as that found to infringe those rights, and if the court or the comptroller finds that it would not have been reasonable, it or he shall reduce the damages to such an amount as it or he thinks just.
(1)Where a person (whether or not the proprietor of, or entitled to any right in, a patent) by circulars, advertisements or otherwise threatens another person with proceedings for any infringement of a patent, a person aggrieved by the threats (whether or not he is the person to whom the threats are made) may, subject to subsection (4) below, bring proceedings in the court against the person making the threats, claiming any relief mentioned in subsection (3) below.
(2)In any such proceedings the plaintiff or pursuer shall, if he proves that the threats were so made and satisfies the court that he is a person aggrieved by them, be entitled to the relief claimed unless—
(a)the defendant or defender proves that the acts in respect of which proceedings were threatened constitute or, if done, would constitute an infringement of a patent; and
(b)the patent alleged to be infringed is not shown by the plaintiff or pursuer to be invalid in a relevant respect.
(3)The said relief is—
(a)a declaration or declarator to the effect that the threats are unjustifiable;
(b)an injunction or interdict against the continuance of the threats; and
(c)damages in respect of any loss which the plaintiff or pursuer has sustained by the threats.
(4)Proceedings may not be brought under this section for a threat to bring proceedings for an infringement alleged to consist of making or importing a product for disposal or of using a process.
(5)It is hereby declared that a mere notification of the existence of a patent does not constitute a threat of proceedings within the meaning of this section.
(1)Without prejudice to the court’s jurisdiction to make a declaration or declarator apart from this section, a declaration or declarator that an act does not, or a proposed act would not, constitute an infringement of a patent may be made by the court or the comptroller in proceedings between the person doing or proposing to do the act and the proprietor of the patent, notwithstanding that no assertion to the contrary has been made by the proprietor, if it is shown—
(a)that that person has applied in writing to the proprietor for a written acknowledgment to the effect of the declaration or declarator claimed, and has furnished him with full particulars in writing of the act in question; and
(b)that the proprietor has refused or failed to give any such acknowledgment.
(2)Subject to section 72(5) below, a declaration made by the comptroller under this section shall have the same effect as a declaration or declarator by the court.
