National Patenting Procedure

The documents required for filing a national application include:

• a request for grant of a patent;
  
• a description of the invention and indication of the International Classification index;
  
• claims;
  
• drawings (if necessary);
  
• an abstract;
  
• Declaration of the Author and a Document in proof of transfer of copyright and related rights (if the inventor and the applicant are not the same person(s) (LT SPB forms);
  
• Power of Attorney (LT SPB Form, notarisation or legalization are not required, may be submitted within 3 months from the filing date);
  
• a priority document certified by the Patent Office of the relevant country (in case the priority under the Paris Convention is claimed). May be submitted within 3 months from the filing date.

Lithuania is a party to the Paris Convention for the Protection of Industrial Property, consequently it is possible to file a national application claiming priority as provided by the said Convention. The Convention priority may be claimed within 12 months from the application filing date in a foreign country.
The period of patenting (from filing to granting a patent) is 10-14 months.

The maximum term of a Lithuanian patent is 20 years, provided annuities are paid in due time (within the last two months of the current year). A
6-months extension of the period for payment is allowed, however the official fee in this case is increased by 50%.

The law currently in force also envisages grant of supplementary protection certificates (SPC) for patents covering active ingredients of a medicine and active substances of a plant protection product. To file a request for a SPC it is necessary to pay a corresping fee and submit a copy of the first authorisation to place a medicine or a plant protection product on the market.
