This statement includes all of the essential elements of a common law trademark statement:

• It identifies the trademark owner (Existube).
• It identifies the goods or services that the trademark is used to identify (product designs created and published on the Existube website).
• It asserts the owner's trademark rights in the mark.
• It warns potential infringers of the consequences of unauthorized use.

To use this statement, simply copy and paste it into your website and marketing materials, and use it prominently on your t-shirts.
In addition to using the trademark statement, there are a few other things you can do to protect your common law trademark rights:

• Use the trademark consistently and conspicuously on your goods and services.
• Keep records of your use of the trademark, such as advertising materials, sales invoices, and customer receipts.
• Conduct a trademark search to see if there are any registered trademarks that are similar to your mark. If you find any similar marks, you should consult with an attorney to assess your risk of infringement.
