To trademark your company name/logo, there are several steps you should take:

1. Conduct a trademark search: Before filing for a trademark, it is important to conduct a search to ensure that your proposed name/logo is not already in use or registered by someone else. This can be done through the United States Patent and Trademark Office (USPTO) database or with the help of an attorney.
2. Determine the class of goods/services: You will need to determine the class of goods/services your trademark will be used for. This information is necessary for filing the trademark application. You can find a list of the classes of goods and services on the USPTO website.
3. File a trademark application: Once you have conducted a trademark search and determined the class of goods/services, you can file a trademark application with the USPTO. The application can be filed online or through the mail. The application requires a fee and a description of the mark.
4. Wait for examination: After filing the application, the USPTO will examine it and determine whether the mark can be registered. This process can take several months.
5. Respond to office actions: If the USPTO finds any issues with the application, it may issue an office action that requires a response. You will need to respond to the office action in a timely manner.
6. Receive your trademark registration: If the application is approved, you will receive a trademark registration from the USPTO. This registration provides you with exclusive rights to use the mark in connection with the goods/services listed in the registration.

It is important to note that trademark laws can be complex and the USPTO may reject an application for a variety of reasons. Therefore, it is recommended that you seek the assistance of a licensed attorney to help with the trademark application process. Additionally, it may be wise to monitor your trademark after registration to ensure that no one else is using your mark without your permission.
