Trademark search is done to certify that any trademark which an applicant wishes to register does not cause probability of confusion with an already applied mark. Trademark is divided in 45 different classes according to the NICE classification. Each of the trademark class depicts distinct set of goods and services. Among 45 classes, 34 classes represent Goods & 11 classes represent Services.
While applying for Trademark registration, it is necessary to choose the appropriate class. Trademark application can be filed in multiple classes, if the activity of the business involves diverse goods or services falling under different trademark classifications.
