Classes to be selected under the Nice Classification in trademark registration are determined on the basis of goods actually manufactured, services rendered, and commercial fields where the enterprise plans to operate within a reasonable term. An applicant must include in their specification list only those classes covering goods or services in which they use their trademark. Establishing uniformity at the international level, the Nice Classification delineates the scope of legal protection conferred through registration. The scope of protection is directly limited to the list of goods and services declared in the application form and affixed to the trademark registration certificate.

In Turkey, trademark registration applications are prosecuted before the Turkish Patent and Trademark Office (TÜRKPATENT) pursuant to the provisions of the Industrial Property Code No. 6769 (IPC). While trademark registration confers exclusive rights upon the proprietor over the sign concerned, such rights become effective solely across classes covered by the registration. Accordingly, existence of a trademark cannot inherently prevent similar uses in unregistered and unrelated sectors.

The Nice Classification is an international classification system providing for registration of goods and services subject to trademark applications in a standardized order worldwide. Applied under the Nice Agreement, to which Turkey is a party, this system consists of 45 classes in total. The first 34 classes are designated for goods, whereas classes 35 through 45 are reserved for services.

The system concerned facilitates search and comparison processes for applicants and registration authorities. Classes in which a trademark is registered definitively determine the field of application of the protection granted under the IPC. A sector not listed during the application stage cannot be inherently included in the scope of protection following registration.

Which sectors and entities are required to use this classification?

All natural and legal persons seeking to obtain protection for a trade name, logo, or product name are required to use the Nice Classification during trademark prosecution. Joint-stock companies, limited liability companies, sole proprietorships, cooperatives, and independent professionals are among addressees of this requirement. Any entity filing an application for registration is obligated to select its field of activity from among these 45 classes and notify TÜRKPATENT accordingly.

When selecting classes, not only current operations but also medium-term business plans must be taken into account. For instance, an enterprise selling apparel in a brick-and-mortar store that concurrently conducts retail sales online must evaluate both the product class and the retail services class. Unnecessary selection of unrelated classes increases registration costs and engenders legal risks.

What occurs if an incorrect class is selected in trademark registration?

Selecting an incorrect or incomplete class in trademark registration leaves the trademark legally unprotected in its primary field of activity and results in severe loss of rights. Where an enterprise manufactures products but selects solely a general service class, it will encounter difficulty in preventing third parties from registering the identical sign for the relevant product group. This condition lays the groundwork for unfair competition disputes and trademark infringement claims.

A five-year consecutive non-use condition also becomes an issue for trademarks registered as a result of misclassification. Pursuant to the provisions of the IPC, revocation of trademarks not put to genuine use within five years of the registration date across registered classes without proper reason may be requested. Hence, adding classes in which no commercial activity is conducted provides no legal certainty and creates a risk of revocation actions.

How are classes of goods and services determined during the application process?

During the application process, classes are determined by individually matching tangible goods and services provided by the enterprise against counterparts in the official list of goods and services. Search engines and international databases provided by TÜRKPATENT are utilized at this stage. Goods and services selected must be formulated clearly, precisely, and in accordance with applicable legislation.

A common error encountered in practice entails incorporating overly broad subheadings into the application that bear no relation to the enterprise. As stated by Attorney & Mediator Billur Güler Aslım, current market share and future projections of an enterprise must be analyzed in a balanced manner when formulating trademark prosecution strategy. An accurate list of goods and services prevents potential oppositions and expedites the registration procedure.

Proceeding on a concrete example clarifies determination. Consider an entrepreneur operating a boutique hotel in Antalya who concurrently produces regional olive oil under their own mark. This entrepreneur must select Class 43 for accommodation services and Class 29 for olive oil production.

Obtaining registration solely in Class 43 covering accommodation services does not directly prevent another enterprise from using the identical name in the olive oil sector. Likewise, registering solely for olive oil leaves commercial investment in accommodation unprotected. For this reason, each operational branch of an enterprise active in multiple fields must be listed independently.

What are the most frequent mistakes made in class selection?

The most frequent mistake made in class selection is attempting to file across all 45 classes or dozens of unrelated classes to encompass sectors where the trademark does not operate. Although this approach is favored under the misconception that it confers absolute protection, it generates substantial costs and elevates opposition risk to a maximum. Furthermore, trademark portfolios become legally vulnerable to revocation actions initiated by third parties for unused classes.

Another common mistake is failure to observe the distinction between retail trade and manufacturing. For instance, a merchant having footwear produced under contract and selling it cannot obtain direct protection in Class 25, which encompasses footwear goods, when registering solely Class 35 covering retail services. Failure to align registration strategy with actual business operations leads to imitation of established commercial goodwill.

Is it possible to add a new class following registration?

Adding a new class to a trademark that has been registered or whose application has been completed is not permissible under the legislation. Under the IPC framework, the scope of a trademark application is frozen upon filing and cannot be broadened. An applicant may only partially withdraw the application or restrict the specification of goods and services.

Where an enterprise expands operations or launches a new product line, it must file an independent trademark application de novo for these new fields. The new application undergoes fresh examination before the Office and is published in the official bulletin for third-party oppositions. Accounting for near-term expansion plans during the initial application therefore saves time and costs.

How do TÜRKPATENT examination and opposition procedures operate?

TÜRKPATENT examines filed applications and selected class lists ex officio, primarily regarding absolute grounds for refusal and formal requirements. Applications that are formally complete or whose deficiencies have been remedied are published in the Official Trademark Bulletin for two months to solicit third-party observations and oppositions. Within this statutory two-month period, proprietors of earlier similar marks may file oppositions against publication alleging similarity of goods and services.

In the absence of oppositions, or where filed oppositions are rejected with finality, the file proceeds to the stage of completing registration deficiencies. Upon payment of the registration fee by the applicant within the notified term, a trademark registration certificate is issued. Where an administrative appeal is not lodged against Office decisions within the prescribed period, or where the appeal is definitively rejected, an action for annulment of the administrative decision may be instituted before the competent Civil Court of Intellectual and Industrial Property Rights. In jurisdictions such as Antalya lacking a specialized standalone court, competent Civil Courts of General Jurisdiction hear these actions.

Identifying the correct Nice classes in trademark prosecution is a strategic legal step safeguarding an enterprise’s commercial future. Deficiently selected classes leave a trademark vulnerable, whereas superfluous classes impose financial burdens and risks of revocation. Formulating a balanced list of goods and services aligned with commercial targets and in full compliance with the statutory framework constitutes the primary prerequisite for protecting market value and legal enforceability of a trademark.
