Publication of the Patents Act, cf Consolidated Act No. 824 of 3 September 1996 as amended by Act No. 972 of 17 December 1997.

Section 1

(1) Any person who has made an invention which is susceptible of industrial application, or his successor in title shall, in accordance with this Act, have the right on application to be granted a patent for the invention and thereby obtain an exclusive right to exploit the invention commercially.

(2) The following subject-matter or activities as such shall, in particular, not be regarded as inventions:

(i)     discoveries, scientific theories and mathematical methods,

(ii)     artistic creations,

(iii)     plans, rules or methods for intellectual activity, for games or for business activity or computer programs,

(iv)     presentation of information.

(3) Methods for surgical or therapeutic treatment or for determination of diagnoses, practised on human beings or animals, shall not be regarded as inventions, either. This provision shall not prevent the grant of patents for products, including substances and compounds, for use in any of these methods.

(4) Patents shall not be granted in respect of

(i)     inventions the exploitation of which would be contrary to law and order or morality, or

(ii)     species of plants or animals or essential biological processes for the production of plants or animals. Patents may, however, be granted for microbiological processes and the products thereof.

Section 2

(1) Patents shall be granted only for inventions which are new in relation to the state of the art prior to the date of filing of the patent application and which, moreover, differ essentially therefrom.

(2) The state of the art shall be held to comprise everything made available to the public by means of a written description, lecture, exploitation or in any other way. The contents of patent applications filed in this country before the said date of filing shall also be regarded as comprised in the state of the art, if such applications are made available to the public in accordance with the rules in section 22 of this Act. The same shall apply to the contents of applications for registration of utility models filed in this country before the said date of filing, if such applications are made available to the public in accordance with the rules relating to utility models. The requirement in subsection I hereof to the effect that the invention shall differ essentially from the state of the art shall, however, not apply in relation to the contents of such applications.

(3) Provisions to the effect that for the purposes of subsection 2 hereof applications provided for in Part 3 of this Act shall in certain cases have the same effect as patent applications filed in this country are laid down in sections 29 and 38 of this Act.

(4) The requirement under subsection 1 hereof that inventions be new shall not prevent the grant of patents for known substances or compounds for use in the methods referred to in section 1 (3) of this Act, provided that the use of such substance or compound is not known for any of those methods.

(5) Patents may, however, be granted for inventions irrespective of the fact that they have been made available to the public within the last 6 months prior to the filing of the application, if this is a consequence of

(i)     evident abuse in relation to the applicant or his legal predecessor, or

(ii)     the fact that the applicant or his legal predecessor has displayed the invention at an official, or officially recognized, international exhibition falling within the terms of the Convention on International Exhibitions, signed at Paris on 22 November 1928.

Section 3

(1) The exclusive right conferred by a patent shall imply that no one, except the proprietor of the patent, may without permission exploit the invention

(i)     by making, offering, putting on the market or using a product which is the subject-matter of the patent, or by importing or possessing the product for these purposes, or

(ii)     by using a process which is the subject-matter of the patent or by offering the process for use in this country, if the person offering the process knows, or it is obvious in the circumstances that the use of the process is prohibited without the consent of the proprietor of the patent, or

(iii)     by offering, putting on the market or using a product obtained by a process which is the subject-matter of the patent or by importing or possessing the product for these purposes.

(2) The exclusive right shall also imply that no one, except the proprietor of the patent, may without permission exploit the invention by supplying or offering to supply any person who is not entitled to exploit the invention with means for working it in this country, if these means relate to an essential element of the invention and the person supplying or offering to supply the means knows, or it is obvious in the circumstances, that these means are suitable and intended for such use. This provision shall not apply when the means are staple commodities, except when the person supplying or offering to supply the means induces the person supplied to commit acts as referred to in subsection I hereof. For the purposes of the 1st and 2nd clause hereof, persons performing acts as referred to in subsection 3 (i), (iii) or (iv) hereof shall not be considered entitled to exploit the invention.

(3) The exclusive fight shall not extend to:

(i)     acts done for non-commercial purposes,

(ii)     acts concerning products put on the market in this country by the proprietor of the patent or with his consent,

(iii) acts done for experimental purposes relating to the subject-matter of the patented invention, or

(iv)     preparation in a pharmacy of a medicinal product according to a prescription in individual cases or acts concerning the medicinal product so prepared.

(4) In respect of acts concerning products put on the market in another Member State which has ratified or acceded to the Agreement relating to Community Patents, Articles 76 and 81 (3) of the Community Patent Convention shall apply.

Section 4

(1) Any person who, at the time when the patent application was filed, was exploiting the invention commercially in this country may, notwithstanding the grant of a patent, continue such exploitation retaining its general character, provided that the exploitation did not constitute an evident abuse in relation to the applicant or his legal predecessor. Such a right of exploitation shall also, under similar conditions, be enjoyed by any person who had made substantial preparations for commercial exploitation of the invention in this country.

(2) The right provided for in subsection I hereof shall only be transferred to others together with the business in which it has arisen or in which the exploitation was intended.

Section 5

(1) Notwithstanding a patent having been granted for an invention, persons other than the proprietor of the patent may exploit the invention by the use of a foreign vehicle, vessel or aircraft when it temporarily or accidentally enters this country.

(2).The Minister of Business and Industry may direct that, notwithstanding the grant of a patent, spare parts and accessories for aircraft may be imported into and used in this country for the repair of aircraft belonging to a foreign state which grants similar rights in respect of Danish aircraft.

Section 6

(1) Application for a patent of an invention which no earlier than 12 months prior to the date of application has been stated in an application relating to patent or utility model registration in this country or patent, inventor’s certificate or utility model protection in another country which has joined the Paris Convention of 20th March 1883 concerning the protection of industrial ownership shall in relation to sections 2(1), 2(2) and 2(4) together with section 4 of this Order on request be seen as being filed at the same time as the earlier application. The same right of priority shall apply even if the application for protection does not originate from a country which has joined the convention when an identical priority from a Danish patent application or utility model application pursuant to bilateral or multilateral agreement is allowed in the country in which the earlier application was filed and this is on conditions and with effects which substantially comply with the convention.

(2) The Minister of Business and industry shall lay down the particulars of the right to claim such priority.

Section 7

(1) The Patent Authority of this country shall be the Patent Office, headed by a Director General, and the Patent Board of Appeal (Board of Appeal for Industrial Property). For the purposes of this Act, the ‘Patent Authority’ means the Patent Authority of this country unless otherwise stated.

(2) The Patent Board of Appeal shall be established by the Minister of Business and Industry for the examination of appeals from decisions of the Patent Office, cf. sections 25 and 67 of this Act, and appeals from decisions pursuant to the Danish Designs Act, the Danish Trade Marks Act, etc. The Patent Board of Appeal shall consist of not more than 18 members who shall be appointed for a term of 5 years. 2 of the members, one of whom shall be the chairman, shall possess the general qualifications for appointment to the office of High Court judge whereas the other members together shall possess the best possible expert knowledge of patents, designs, trade marks and matters placed under the authority of the Patent Board of Appeal by other legislation. They shall be graduates from the Technical University of Denmark (Danmarks Tekniske Højskole), another institution of higher education or have acquired the necessary expert knowledge in another way.

(3) Having regard to the circumstances of each particular case, the chairman shall decide which and how many of the members of the Board are to participate in the examination of the case.

(4) The Minister of Business and Industry shall lay down further rules for the activities of the Patent Board of Appeal including rules relating to proceedings and rules to the effect that the appellant shall pay a fee for the examination of an appeal.

Section 8

(1) An application for a patent shall be filed with the Patent Authority or, in the cases referred to in Part 3 of this Act, with the patent authority of a foreign state or with an international organisation.

(2) The application shall contain a description of the invention, including drawings where necessary, and a precise statement of the matter for which protection by the patent is sought (one or more claims). The fact that the invention relates to a chemical compound shall not imply that specific use must be indicated in the claim. The description shall be sufficiently clear to enable a person skilled in the art to carry out the invention. An invention which relates to or involves the use of biological material shall, in the cases specified in section 8 a of this Act, only be regarded as disclosed in a sufficient clear manner, if also the requirements of section 8 a are fulfilled.

(3) The application shall also contain an abstract of the description and claims. The abstract shall merely serve for use as technical information and may not be taken into account for any other purpose.

(4) The name of the inventor shall be indicated in the application. If the applicant is not the inventor, he shall prove his right to the invention.

(5) The applicant shall pay the prescribed application fee. For the patent application the prescribed renewal fee in respect of each fee year beginning before the application is finally decided upon shall also be paid. The fee year shall comprise 1 year and shall the first time be reckoned from the date of filing of the application and thereafter from the corresponding day of the calendar year.

Section 8 a

(1) If, in order to carry out the invention, this involves the use of biological material which is neither available to the public nor describable in the documents of the application so as to enable a person skilled in the art to carry out the invention, a sample of the biological material shall be deposited not later than on the date of filing of the application. The sample shall thereafter always be deposited in such manner that any person entitled under this Act to a sample of the biological material may have the sample furnished in Denmark. The Minister of Business and Industry shall lay down rules as to where deposits may be made.

(2) If a deposited sample ceases to be viable, or if for any other reason a sample cannot be furnished, the sample may be replaced by a new sample of the biological material within the prescribed period and otherwise in accordance with rules laid down by the Minister of Business and Industry. If so, the new deposit shall be deemed to have been made already on the date of the previous deposit.

Section 9

If the applicant so requests and pays the prescribed fee, the Patent Authority shall, in accordance with rules laid down by the Minister of Business and Industry, cause the application to be searched by an International Searching Authority under the provisions of Article 15 (5) of the Patent Cooperation Treaty, done at Washington on 19 June 1970.

Section 10

In the same application a patent may not be applied for in respect of two or more mutually independent inventions.

Section 11

If a patent is applied for in respect of an invention which is disclosed by the applicant in an earlier patent application in which no final decision has been given, the later application shall, at the request of the applicant and on the conditions laid down by the Minister of Business and Industry, be deemed to have been filed at the time when the documents disclosing the invention were received by the Patent Authority.

Section 12

If the applicant is not a resident of this country, he shall have an agent residing in this country to represent him in all matters concerning the application.

Section 13

An application for a patent may not be amended in such a way that protection is claimed for subject-matter which was not disclosed in the application at the time when it was filed.

Section 14

(Repealed).

Section 15

(1) If the applicant has not complied with the requirements of the application, or if the Patent Authority has other objections to the acceptance of the application, the applicant shall be notified accordingly and be invited to file his observations or to correct the application within a time limit to be specified. The Patent Authority may, however, make such amendments in the abstract as it finds necessary without consulting the applicant.

(2) If the applicant fails to file the required observations or to take steps to correct the application within expiry of the time limit, the application shall be shelved. The notification referred to in subsection 1 hereof shall contain information to that effect.

(3) The examination of the application shall, however, be resumed if the applicant submits his observations or takes steps to correct the application within 4 months after expiry of the specified time limit and pays the prescribed resumption fee.

(4) If any renewal fee is not paid according to sections 8,41 and 42 of this Act, the application shall be shelved without previous notification. In the case of an application shelved for that reason the proceedings for grant may not be resumed.

Section 16

If, after having received the applicant’s reply, the Patent Authority still has objections to the acceptance of the application, and the applicant has had an opportunity to comment on the objections, the application shall be refused, unless the Patent Authority considers it necessary once more to invite the applicant under section 15 (1) of this Act.

Section 17

(1) If any person claims before the Patent Authority that he, and not the applicant, is entitled to the invention, the Patent Authority may, if it finds the question doubtful, invite him to bring it before the courts within a time limit to be specified. If the invitation is not complied with, the Patent Authority may disregard the claim when deciding on the patent application. Information to that effect shall be given in the invitation.

(2) If legal proceedings have been instituted concerning the right to an invention for which a patent has been applied for, the proceedings for grant may be suspended, until a final decision has been given in the legal proceedings.

Section 18

(1) If any person proves to the Patent Authority that he, and not the applicant, is entitled to the invention, the Patent Authority shall transfer the application to the said person, if he so requests. The transferee shall pay a new application fee.

(2) If a request has been made for the transfer of a patent application, the application shall not be shelved, refused or accepted until a final decision has been made on request.

Section 19

(1) If the application complies with the requirements, and no objections have been found to the grant of a patent, and it has been established that the applicant approves the text on the basis of which patent may be granted, the Patent Authority shall notify the applicant to the effect that patent may be granted against payment of the prescribed fee for publication of the patent specifications.

(2) After the Patent Authority has submitted notification as mentioned in subsection 1 the patent claims shall not be amended in such a manner that the scope of the patent protection is extended.

(3) The fee for publication of the patent specifications shall be paid within 2 months after the Patent Authority has forwarded a notification under subsection 1 hereof. Failure to do so shall cause the application to be shelved. However, proceedings will be resumed, if the applicant pays the patent grant fee and the prescribed resumption fee within 4 months after expiry of the time limit.

Section 20

(1) When the requirements in section 19 of this Act have been complied with, the Patent Authority shall grant the patent and issue letters patent. The grant of patent shall be advertised at the same time.

(2) Patent specifications including description, claims and abstract, shall be obtainable from the Patent Authority at the same time as the grant of patent is advertised. The patent specifications shall state the proprietor of the patent and the inventor.

Section 21

(1) Any person shall be entitled to file an opposition with the Patent Authority against a patent which has been granted. The opposition shall state the grounds on which the opposition is filed and shall be submitted to the Patent Authority within 9 months from advertisement of the grant of patent. The opposition shall be accompanied by the prescribed fee.

(2) An opposition shall only be filed on the grounds that the patent has been granted irrespective of the fact that

(i)     the requirements in sections 1 and 2 of this Act are not complied with,

(ii)     it relates to an invention which has not been described in a sufficiently clear manner as to enable a person skilled in the art to carry out the invention on the basis of the description, or

(iii)     the subject-matter extends beyond the contents of the application filed.

(3) The Patent Authority shall advertise the filing of an opposition.

Section 22

(1) As from the date on which patent is granted, the files of the application shall be available to the public.

(2) When 18 months have elapsed from the date of filing or, if priority has been claimed under section 6 of this Act, from the date on which priority is claimed, the files shall be available to the public, even if patent has not been granted. If a decision has been made to shelve or to refuse the application, the files shall, however, not be available unless the applicant requests resumption of the proceedings, appeals against the refusal or requests re-establishment of rights under sections 72 or 73 of this Act.

(3) At the request of the applicant, the files shall be made available earlier than prescribed in subsections 1 and 2 hereof.

(4) When the files are made available under subsection 2 or 3 hereof, a notice to that effect shall be published.

(5) If a document contains business secrets which do not relate to an invention for which patent is applied for or has been granted, the Patent Authority may, on request, when circumstances make it desirable, decide that the document shall not be available or only available in part. If such a request has been filed, the document shall not be made available until a decision has been made or during the period within which the decision may be appealed against. An appeal shall have suspensive effect.

(6) If a sample of biological material has been deposited under section 8 a of this Act, any person shall have the right to obtain a sample when the files become available under subsections 1, 2 or 3 hereof. This does not imply, however, that any sample shalle be furnished to any person who, according to the rules laid down in or pursuant to law, is not allowed to handle the deposited material. Nor shall any sample be furnished to any person if, due to the dangerous properties of the material, his handling of the sample is supposed to involve obvious danger.

(7) Notwithstanding subsection 6 hereof, the applicant may request that until a patent has been granted or the application has been finally decided upon without having resulted in the grant of a patent the furnishing of a sample shall only be effected to an expert in the art. The Minister of Business and Industry shall lay down provisions governing the time limit for the submission of such a request and prescribing who may be used as an expert. The Minister of Business and Industry shall lay down provisions for the submission of a request for furnishing.

(8) The request for the furnishing of the sample shall be filed with the Patent Authority and shall contain a declaration to observe the restrictions on the use of the sample which appear from rules laid down by the Minister of Business and Industry. If the sample is to be furnished to an expert in the art, the declaration shall instead be given by the latter.

Section 23

(1) If an opposition has been filed, the proprietor of the patent shall be notified accordingly and be given an opportunity to file his observations on the opposition.

(2) The Patent Authority may examine an opposition even though the patent has terminated or will terminate under sections 51, 54 or 96 of this Act, even if the opposition is withdrawn, or even if the opponent dies or loses his capacity to enter into legal transactions.

(3) The Patent Authority may revoke a patent or maintain it unamended or amended. If the Patent Authority finds that the patent may be maintained as amended, and it has been established that the proprietor of the patent consents to this, the patent specifications shall be amended accordingly after the proprietor of the patent has paid the prescribed fee for publication hereof. Copies of the amended patent specifications shall be obtainable from the Patent Authority.

(4) If the proprietor of the patent does not approve the maintenance of the patent as amended or does not pay the fee for publication of new patent specifikations in time, the patent shall be revoked.

(5) The Patent Authority shall advertise its decision on the opposition.

Section 24

(1) An appeal from the final decision of the Patent Office concerning a patent application may be filed by the applicant with the Patent Board of Appeal. The proprietor of the patent may file an appeal with the Patent Board of Appeal, if a patent has been revoked, or if the Patent Office finds that the patent may be maintained as amended following an opposition. The opponent may file an appeal with the Patent Board of Appeal, if a patent is maintained unamended, or if the Patent Office finds that the patent may be maintained as amended despite a duly filed opposition. If the opponent withdraws his appeal, such appeal may nevertheless be examined when circumstances make it desirable.

(2) Decisions refusing a request for resumption under section 15 (3), or section 19 (3) of this Act or complying with a request for transfer under section 18 of this Act may be appealed against by the applicant. Decisions rejecting a request for the transfer of the application may be appealed against by the person making the request.

(3) Decisions refusing a request under section 22 (5) of this Act may be appealed against by the person making the request.

Section 25

(1) Appeals under section 24 of this Act shall be filed with the Patent Board of Appeal not later than 2 months after the date on which the party concerned was notified of the decision by the Patent Office. The prescribed fee shall be paid within the same time limit. Failure to do so shall cause the appeal to be refused.

(2) The decisions of the Patent Board of Appeal may not be brought before any higher administrative authority.

(3) Proceedings to test decisions of the Patent Office which may be appealed against to the Patent Board of Appeal may not be brought before the courts until the decision of the Patent Board of Appeal has been given, cf. however sections 52 and 53 of this Act. Proceedings to test decisions by which the Patent Board of Appeal refuses an application for a patent or revokes a patent shall be brought within 2 months after the date on which the party concerned was notified of the decision.

(4) The provisions of section 22 (5) of this Act shall apply mutatis mutandis with respect to documents received by the Patent Board of Appeal.

Section 26

If an application which is available to the Public is finally refused or shelved, notice hereof shall be published.

Section 36

(1) If any part of an international patent applacation has not been the subject of an international search or an international preliminary examination because the application has been deemed to relate to two or more mutually independent inventions, and the applicant has not paid the additional fee under the Treaty within the prescribed time limit, the Patent Authority shall review the finding to determine whether it was justified. If this is found to be the case, the said part of the application shall be considered withdrawn before the Patent Authority, unless the applicant pays the prescribed fee within 2 months after the date on which the Patent Authority notified him of the result of the review. If the Patent Authority considers that the finding was not justified, it shall proceed with the examination and other processing of the application in its entirety.

Section 58

(1) Any person who intentionally or negligently commits patent infringement shall be liable to pay a reasonable compensation for the exploitation of the invention as well as damages for the further injury which the infringement may have caused.

(2) If any person commits patent infringement which is not intentional or due to negligence, he shall be liable to pay compensation and damages under the provisions of subsection 1 hereof, if and to the extent this is found reasonable.

Section 59

(1) In the case of patent infringement the court may, to the extent this is found reasonable and when so claimed, make decisions to prevent the abuse of products manufactured in accordance with the patented invention or of any apparatuses, tools or other articles the use of which would involve patent infringement. It may thus be decided that the article shall be altered in a specified manner or destroyed or, in the case of a patented article, that it shall be surrendered to the injured party against compensation. This, however, shall not apply to any person who in good faith has acquired the said article or has acquired rights in respect of the article, and who has not himself committed patent infringement.

(2) Under very special circumstances, the court may, notwithstanding the provisions in subsection 1 hereof and when so claimed, grant permission to dispose freely of the products, apparatuses, tools and other articles referred to in subsection 1 hereof during the term of the patent or part of that term against a reasonable compensation and on reasonable conditions in other respects.

Section 60

(1) If any person exploits an invention commercially without permission after the files of the application have been made available to the public, and the application results in a patent, the provisions concerning patent infringement, with the exception of section 57 of this Act, shall apply mutatis mutandis. The protection conferred prior to grant of patent shall, however, only extend to subject-matter disclosed both in the claims as worded at the time when the application was made available to the public and in the patent as granted or maintained in amended form under section 23 (3) of this Act.

(2) The person concerned shall only be liable to the extent referred to in section 58 (2) of this Act to pay damages for injury caused by infringement committed prior to the advertisement of the grant of a patent under section 20 of this Act.

(3) Claims for damages under subsection 1 hereof shall not be statute-barred earlier than 1 year after the grant of the patent.

Section 61

Section 62

(1) Any person who, in the cases referred to in section 56 of this Act, fails to comply with his obligations or gives false information shall be punished by a fine, provided that a severer punishment is not provided for by other legislation, and shall be liable to compensate the injury caused thereby to the extent this is found reasonable.

(2) The provisions of section 57 (2) and (3) of this Act shall apply mutatis mutandis.

Section 63

(1) Any person who institutes proceedings for the revocation of a patent, for the transfer of a patent or for the grant of a compulsory licence shall at the same time notify the Patent Authority accordingly and by registered mail notify any licensee who is entered in the Register of Patents and whose address is recorded in that Register of the proceedings.
