One of the most common reasons trademark applications are rejected is because the applied-for trademark is too similar to an already registered one and there’s a likelihood of confusion. This means that customers are likely to think your goods or services come from the same source as another party’s goods or services. So, before you apply to register a trademark, search to see if someone else already registered that trademark or a similar one.Although the trademark examining attorney assigned to your application will also conduct a search, they will only determine whether there are conflicting trademarks in our database. So, you should be aware of any other potentially conflicting trademarks. It’s your responsibility to search state trademark databases and the internet.
