Overview of Patent Registration in Estonia
When considering the protection of biopharmaceutical patents in Estonia, it is crucial to understand the overall patent registration process. The Estonian Patent Office oversees this process, which includes both formal and substantive examinations[1][5].
Patentability Requirements
Novelty, Inventive Step, and Industrial Applicability
For a biopharmaceutical invention to be patentable in Estonia, it must meet the standard criteria of novelty, inventive step, and industrial applicability. These requirements are in line with the TRIPS Agreement and European Patent Convention (EPC) standards, ensuring that the invention is new, involves an inventive step, and is capable of industrial application[2][5].
Exceptions to Patentability
Estonian legislation, like other jurisdictions, allows for certain exceptions to patentability. These include inventions whose commercial exploitation needs to be prevented to protect human, animal, or plant life or health, and diagnostic, therapeutic, and surgical methods for treating humans or animals[2].
Validity Term and Extensions
Standard Validity Term
The validity term of a patent in Estonia is 20 years from the filing date. This applies to all types of patents, including biopharmaceuticals[1][5].
Extensions for Pharmaceutical Patents
For pharmaceutical patents and patents for agrochemicals, it is possible to apply for an extension of the validity term by an additional 5 years through a Supplementary Protection Certificate (SPC)[1].
Filing and Examination Process
Filing Requirements
To file a patent application in Estonia, applicants must provide detailed documentation, including the applicant's and inventor's names, addresses, and citizenships, a specification with claims, abstract, and drawings, and a Power of Attorney if necessary. For conventional applications, a certified copy of the priority document must be filed within 16 months from the priority date[1][5].
Formal and Substantive Examination
The patent application undergoes a formal examination lasting one month, followed by an automatic substantive examination upon publication of the application. No separate request is needed for the substantive examination[1][5].
Representation for Foreign Applicants
Foreign applicants must be represented by a registered Estonian patent attorney throughout the patent prosecution process[1][5].
Scope of Claims
Product-by-Process Claims
For biopharmaceutical products defined by a process of manufacture, the claim must be directed to the product itself, not the process. The product must fulfill the requirements for patentability, such as being new and inventive. The technical content of the invention lies in the technical properties imparted to the product by the process[4].
Second Medical Use Claims
In the case of second medical use claims, the patent application must include evidence to support the claimed therapeutic application. Post-filed evidence cannot be used to remedy the lack of sufficient disclosure at the time of filing. The application must render it credible that the known therapeutic agent is suitable for the new therapeutic application[3].
Enforceability
Patent Maintenance and Fees
To maintain a patent in Estonia, annual fees are due starting from the first year following the filing date. These fees must be paid by the last day of the month in which the anniversary of the filing date occurs, with a six-month grace period available upon payment of a surcharge[5].
Supplementary Protection Certificates (SPCs)
For extended protection through SPCs, the patent holder must apply for this extension, which can add up to 5 years to the standard 20-year validity term for pharmaceutical and agrochemical patents[1].
Novelty Grace Period
Estonian law provides a novelty grace period of 12 months from the disclosure of the information on the invention before filing an application. This allows inventors to disclose their invention publicly without losing the right to file a patent application within this period[1][5].
Utility Models
While utility models are an alternative form of protection in Estonia, they are not applicable to inventions in the field of biotechnology. Utility models undergo only formal examination and have a validity term of 10 years from the filing date[5].
International Considerations
European Patents
Patent protection in Estonia can also be obtained through European Patents validated in Estonia. This provides a broader scope of protection across multiple European countries[5].
