    ES.04 APPOINTMENT OF AN AGENT
    SPL Art. 175,
    SRD Art. 108

    An agent must be appointed by filing a power of attorney if the applicant is not resident in Spain or in a country of the European Union. However, the submission of a separate power of attorney or a copy of a general power of attorney is not required, except in case of reasonable doubt regarding the agent’s entitlement to act; upon appointment of, or for any paper submitted by, an agent who was not indicated in the request form at the time of filing; or when filing an assignment, a change in the name of the applicant or the proprietor of the patent, a license, a withdrawal, a limitation or revocation or an opposition to a patent or to a utility model. A model of power of attorney is given in Annex ES.III.
    ES.05 ANNUAL FEES
    SPL Art. 184,
    SPL Art. 185

    After a patent has been granted, a fee must be paid for maintaining the patent in force. For this purpose, annual fees are divided into those which became due before the grant of the patent and those which become due after the grant. Payment must be made for the third, and each following year after the international filing date which has already expired at the time of granting the patent, within three months after publication in the Industrial Property Bulletin of a mention of the grant of the patent. Payment can still be made, together with a 25% surcharge, within three months or, together with a 50% surcharge, before the expiration of the sixth month after the due date. Annual fees that become due after the grant of the patent must be paid within three months after the due date, namely the expiration of the month containing the anniversary of the international filing date. Payment can still be made, together with a 25% surcharge, within three months or, together with a 50% surcharge, before the expiration of the sixth month after the due date. Once the sixth month has expired, the patent may still be maintained in force by paying, before the due date for the next annual fee, the corresponding fee with a 50% surcharge and the regularization fee. The amounts of the annual fees are indicated in Annex ES.I.
    ES.06 DEED OF ASSIGNMENT
    SRD Art. 101
    When the applicant claims the priority of an earlier application filed by an applicant who is not identical with the applicant of the international application, a deed (or deeds) of assignment must be furnished. For details, refer to the sample of such deed (not an official form) in Annex ES.III. Legalization is not required. For time limits, refer to the Summary. When the applicant is not the inventor, it is sufficient to designate the inventor and to indicate how the applicant acquired the right to the patent. Where the applicant uses the form for national phase entry, it is not necessary to submit a deed of assignment with regard to the applicant’s entitlement to claim priority of the earlier application as that form contains a statement in this regard (refer to Box 6 of form for national phase entry (Annex ES.II)).
    ES.07 AMENDMENT OF THE APPLICATION
    SPL Art. 48,
    SRD Art. 101.2(e),
    PCT Article 28,
    PCT Article 41

    The applicant may amend or correct the claims, the description, and the drawings before the grant of a patent according to the provisions of the law, provided the scope of the subject matter of the application does not go beyond the disclosure in the international application as filed. Any request for amendment is subject to the payment of a fee for modification indicated in Annex ES.I.
    ES.08 REVIEW UNDER PCT ARTICLE 25
    SPL Art. 44,
    SPL Art. 54,
    PCT Article 25,
    PCT Rule 51

    The applicable procedure is outlined in paragraphs NP 6.018 to NP 6.021 of the National Phase. If, upon review under PCT Article 25, the Office denies an error or omission on the part of the receiving Office or the International Bureau, a petition against this decision may be lodged within one month from the date of publication of the decision in the Industrial Property Bulletin. Within the same one-month time limit, a fee for petition must be paid (for the amount, refer to Annex ES.I). If the Office confirms its decision, a judicial appeal may be lodged with the competent commercial court.
    ES.09 EXCUSE OF DELAYS IN MEETING TIME LIMITS
    SPL Art. 44,
    SPL Art. 53,
    SPL Art. 54,
    SRD Art. 69,
    PCT Article 24(2),
    PCT Article 48(2)

    Reestablishment of rights may be requested where the applicant was unable to observe a time limit during the international phase or before the Office, in spite all due care required by the circumstances having been taken. A request for reestablishment must be filed with the Office in writing and the omitted act must be completed. The request must state the grounds on which it is based and must set out the facts to which it refers. If the Office refuses the reestablishment of rights, an administrative appeal may be lodged within one month after the publication of the final decision of the Office in the Industrial Property Bulletin. Nevertheless, certain matters are excluded from the reestablishment of rights. Some time limits may be extended for two months by the Office provided that the request for extension is made before the expiration of the time limit. Any proceeding whose time limit falls on a Saturday, a Sunday or a public holiday will be considered fulfilled in due time if it is done on the first working day following that Saturday, Sunday or public holiday.
    ES.10 UTILITY MODEL
    SPL Art. 141,
    PCT Article 4(3),
    PCT Article 43,
    PCT Rule 49bis.1(a),
    PCT Rule 49bis.1(b),
    PCT Rule 76.5

    If the applicant wishes to obtain a utility model instead of a patent in Spain, on the basis of an international application, the applicant, when performing the acts referred to in Article 22 or 39, shall so indicate to the Office, preferably in the corresponding box of the application form.
    ES.11
    SRD Art. 58
    The requirements for the national phase are basically the same as for patents.
    ES.12
    PCT Article 7(2)(ii),
    PCT Rule 7.2

    Where the international application does not contain drawings, the applicant must furnish the drawing(s) within the time limit applicable under PCT Article 22 or 39(1). Where the applicant does not furnish the drawing(s) within that time limit, the Office will invite him to furnish the drawing(s) within a time limit fixed in the invitation. Where an international patent application is converted into a utility model application (refer to the next paragraph), the drawing(s) must be submitted together with the request for conversion.
    ES.13 CONVERSION
    SPL Art. 51,
    SRD Art. 46

    When an international application has already entered into the national phase requesting the protection for a patent and fulfilled all the requirements, during the national proceedings, the patent application may be converted into a utility model application, as indicated in the Summary. The conversion requires payment of a fee specified in Annex ES.I. The request for conversion may be submitted at any time before the completion of the substantive examination of the patent application.
    ES.14
    SRD Art. 46
    When an international application has already entered the national phase requesting the protection for a utility model and fulfilled all the requirements, during the national proceedings, the utility model application may be converted into a patent application, as indicated in the Summary. The conversion is subject to the payment of a fee for conversion indicated in Annex ES.I and may be requested before the grant of the utility model.
