Before beginning to examine your application, we will carry out a thorough check of the application form(s) and any attachments. This is to see if all the necessary parts of the form(s) have been filled in, if they are correct and if any required information is missing. If any required information is missing, we will ask you to provide the information to remedy the deficiencies . Some amendments are very minor and will not affect the filing date of your application, e.g. the class number of the applied for goods. Others are more important and will therefore affect the filing date, e.g. you have not provided the representation of your trademark. Also, major changes to the application will not be accepted, for example, changes to the representation of the trademark.
