Most will tell you that it’s highly advisable to trademark at least your name and logo in order to prevent others from ripping off your startup and be provided a legal recourse if this ever happens.
Keep in mind that logo, company name, and slogan will require three separate filings with the USPTO. More on that here:
Regarding the costs, at a minimum each filing will cost you $275 in filing fees with the Office. If you’re looking to protect your trademark in more than one category of goods and service, you will need to pay an additional filing fee for each category.
Since the trademark application process can be complex, many seek the assistance of an Intellectual Property Attorney to do the heavy lifting for them.
There are many legal requirements, strict time deadlines, and the filing fees are not refunded in case you mess up. An attorney will do the research to make sure the mark isn’t already taken, ensure the filing gets accepted by the Office, and provide sound legal advice throughout the whole process.
