What can be protected?

Patent protection is available for inventions in any field of technology, provided that the invention:

• is new (novel);
• involves an inventive step; and
• is industrially applicable.

What cannot be protected (as such / general exclusions)

As a rule, patent protection does not extend to the following subject matter as such:

• discoveries, scientific theories, and mathematical methods;
• aesthetic creations;
• schemes, rules, and methods for performing mental acts, playing games, or doing business;
  presentations of information;
• computer programs as such.

In addition, inventions whose commercial exploitation would be contrary to public order or morality are excluded.

Filing and priority

Paris Convention priority may be claimed within 12 months from the earliest filing date (priority date).

Foreign applicants are generally required to act before the State Intellectual Property Office of the Republic of Croatia through a locally authorized representative (Croatian patent attorney).

Language and translation requirements

Applications must be filed in Croatian.
Where supporting documents are in a foreign language, translations may be required (depending on the document and procedural stage).

Examination and office actions

National patent applications typically undergo:

1. formal examination, and
2. substantive examination (patentability assessment) under the applicable procedure.

Term and maintenance

Standard patent term: 20 years from the filing date, subject to payment of annual maintenance fees.

Term extensions / SPC (important)

Croatia provides for Supplementary Protection Certificates (SPCs) for certain regulated products (notably medicinal products and plant protection products) in qualifying cases. SPCs may extend effective protection beyond the 20 year patent term, but generally by no more than 5 years (subject to SPC eligibility and calculation rules).

• application form;
• description;
• claims;
• abstract;
