Validation of European patents in the Lao People's Democratic Republic
I. Basic principles
The system for validating European patents in the Lao People's Democratic Republic (Lao PDR) introduced under the validation agreement between the European Patent Organisation and the Ministry of Industry and Commerce of Lao PDR enters into force on 1 April 2025.1
The validation system provides European patent applicants with a simple and cost-effective way of obtaining patent protection in Lao PDR. At the applicant's request, and on payment of the prescribed fee, European applications (direct or Euro-PCT) and patents can be validated in Lao PDR, where they will have the same effects as national applications and patents. The validation procedure is not based on direct application of the EPC but is governed solely by national law.
The rules on the validation system in Lao PDR are set out in parts I to V of the Instruction for Validation of European Patents in Lao PDR and the associated Additional Recommendation, pursuant to the Patent Law of Lao PDR.2
These rules are set out in section VI below. The flowcharts in section VII are a handy guide illustrating the steps in the procedure for validation via the two filing routes.
II. Validation procedure
Validation of European patent applications
1. Validation is at the applicant's request. A request is deemed to be made for any European patent application filed on or after 1 April 2025 (part II, Article 2(1) of the Instruction for Validation of European Patents in Lao PDR). Validation is not available for applications filed prior to that date, or for any European patents resulting from such applications.
2. The EPO and the Ministry of Industry and Commerce, Department of Intellectual Property of Lao PDR (DIP) have agreed to fix the validation fee for Lao PDR at EUR 180, as published in the decision of the President of the EPO dated 19 February 2025.3 It must be paid to the EPO (not DIP) within six months from the date on which the European Patent Bulletin mentions the publication of the European search report (part III, Article 1(1) of the Instruction for Validation of European Patents in Lao PDR).
3. After expiry of the basic time limit, the validation fee can still be paid, together with a 50% surcharge,4
(a) within a two-month "grace period" from expiry of the basic time limit, or
(b) along with the further processing concerning the designation fee: within a two-month period from notification of a communication noting a loss of rights due to non-payment of the designation fee under Rule 112(1) EPC.
4. No notification of non-compliance with the basic time limit or expiry of the grace period is issued. Nor is re-establishment of rights possible in respect of the periods for paying the validation fee.
5. The EPO's Rules relating to Fees apply mutatis mutandis to payment of the validation fee (part III, Article 1(3) of the Instruction for Validation of European Patents in Lao PDR). The fee is specified in the schedule of fees and expenses published in the EPO's Interactive schedule for all fees.5
6. If the validation fee is not paid in time, the validation request is deemed withdrawn (part II, Article 2(3) of the Instruction for Validation of European Patents in Lao PDR). It is by paying the validation fee that applicants retain the option to validate their European patent application or European patent in Lao PDR. The declaration in section 33.26 of the request for grant of a European patent (EPO Form 1001, available from 1 April 2025 in the EPO's online filing tools and for download on epo.org) is merely an expression of their intention.
7. Applicants can withdraw their validation request at any time by informing the EPO accordingly. The request will also be deemed withdrawn if by final decision the European patent application is refused (part II, Article 2(3) of the Instruction for Validation of European Patents in Lao PDR). Validly paid validation fees will not be refunded (part III, Article 1(3) of the Instruction for Validation of European Patents in Lao PDR).
8. If a European patent application is validated in Lao PDR, any European divisional application arising from it can also be validated.
Validation of Euro-PCT applications
9. Validation is also available for international applications under the PCT (number (1) of the Additional Recommendation) filed on or after 1 April 2025 unless designation of the EPO and/or Lao PDR has been withdrawn.
10. The procedure for Euro-PCT applications is the same as for European ones, except that the validation fee upon entry into the European phase must be paid to the EPO within 31 months from the filing date (or earliest priority date) or within six months from the date of publication of the international search report (ISR), whichever time limit expires later (part III, Article 1(1) of the Instruction for Validation of European Patents in Lao PDR).
11. If the application enters the European phase early, before the end of the 31-month period under Rule 159(1) EPC, the applicant must fulfil the entry requirements as if that period expired on the date of the request for early processing. Thus, payment of the validation fee depends on when early processing is requested – i.e. on whether the time limit for paying it has already expired on the date the request is made. If, on that date, the ISR has not yet been published, the validation fee can still be paid within six months from the date of the ISR's publication.
III. Effects of validation
12. Under part II, Article 3(1) of the Instruction for Validation of European Patents in Lao PDR, a European patent application for which validation has been requested is equivalent to a regular national application, and after publication confers provisional protection under part II, Article 3(2) of the Instruction for Validation of European Patents in Lao PDR, provided the applicant files the claims with the DIP in Lao and pays the prescribed fee. The DIP will publish these claims.
13. Once the EPO publishes the mention of grant, a European patent validated in Lao PDR has the same effects as a national patent (under part II, Article 4(1) of the Instruction for Validation of European Patents in Lao PDR), provided that within three months of that publication the proprietor files a Lao translation of the claims with the DIP and pays the prescribed publication fee (part II, Article 4(2) of the Instruction for Validation of European Patents in Lao PDR). Proprietors will have a further three months to file this translation if they pay, within this additional period, a 100% surcharge on the prescribed publication fee (part II, Article 4(6) of the Instruction for Validation of European Patents in Lao PDR).
14. Under part II, Article 5(1) and (2) of the Instruction for Validation of European Patents in Lao PDR, the text of a European patent application or a European patent in the language of the proceedings before the EPO shall be the authentic text in any proceedings in Lao PDR. However, the translation into Lao filed with the DIP shall be regarded as authentic, except in revocation proceedings, should the European patent application or European patent in the language of the translation confer protection which is narrower than that conferred by it in the language of the proceedings before the EPO. The applicant or patent proprietor can file a corrected translation, which will take effect after it has been made available to the public.
15. Part II, Article 6 of the Instruction for Validation of European Patents in Lao PDR covers cases of conflict between European and national applications or patents. It corresponds to Article 139(1) and (2) EPC, and makes clear that, for subsequent Lao applications an earlier European application validated in Lao PDR has the same prior-art effect as a national application. However, it only has such effect if the validation fee has been paid, thereby ensuring that not every European application counts as a prior right. The same applies if an earlier national application or patent is prejudicial to a later European patent validated in Lao PDR.
16. If a patent validated in Lao PDR is subsequently amended in opposition or limitation proceedings before the EPO, the patent owner will, within three months of the date on which the mention of the decision to maintain the European patent as amended or to limit it was published, furnish the DIP with a translation into Lao of the amended claims and pay the prescribed publication fee (part II, Article 4(3) of the Instruction for Validation of European Patents in Lao PDR). The translation may still be validly filed within an additional period of three months of expiry of the basic time limit, provided that a 100% surcharge on the publication fee is paid within this additional period (part II, Article 4(6) of the Instruction for Validation of European Patents in Lao PDR).
17. The effects of validated European patents and applications can lapse retroactively. For example, the provisional protection conferred by the translation of the claims of a European application published in Lao PDR will be lost ab initio if the validation request subsequently lapses (part II, Article 3(3) of the Instruction for Validation of European Patents in Lao PDR). Similarly, to the extent that a patent granted for an application is revoked in EPO opposition or revocation proceedings or limited in EPO limitation proceedings, that provisional protection and the patent's effects will be lost ab initio (part II, Article 4(7) of the Instruction for Validation of European Patents in Lao PDR).
18. Renewal fees for validated European patents are payable to the DIP (not the EPO), under the provisions governing national patents, for the years following that in which mention of grant of the European patent was published (part III, Article 2(1) of the Instruction for Validation of European Patents in Lao PDR).
19. The Lao provisions on the revocation of national patents apply to validated European patents.
IV. Informing the public
20. The European Patent Register gives details about the validation of European patent applications and patents, recording the states for which validation has been requested and the relevant fee paid, and the lapse of any validation request already published in the register. The European Patent Bulletin and the patent documents published by the EPO also mention any validation of European applications and patents.
21. Once the validation fee has been paid, the EPO will inform the DIP of the European applications for which validation has been validly requested. The DIP will publish this information as soon as possible, but no earlier than 18 months from the relevant priority date (part II, Article 2(2) of the Instruction for Validation of European Patents in Lao PDR). Lapses of validation requests will be published if details of the validation have already been published.
22. The DIP will also publish the translations of the claims of validated European patents filed by the applicant under part II, Article 4(2) and (5) of the Instruction for Validation of European Patents in Lao PDR, as well as of amended claims of European patents filed by the applicant under part II, Article 4(3) and (5) of the Instruction for Validation of European Patents in Lao PDR, and make known their subsequent fate in accordance with the provisions governing national patents.
V. Applicability of national law
23. For the purposes of validation, the EPO acts purely on the basis of the validation agreement with Lao PDR. The procedure itself and the legal effects of validation are governed solely by the national law of Lao PDR.
24. Since, therefore, any EPO action relating to validation is not taken by virtue of the EPC and is instead subject to national law, the EPC provisions on legal remedies and appeals do not apply.
