KDP Trademark Checker: Guide to Safeguard Your KDP Account

Yesterday, I almost infringed while creating a low content book for amazon kdp. Luckily, before hitting the publish button I thought why not check my title for a possible trademark infringement. 

So, I went on to the USPTO trademark search site and did a search for my book title.  And to my astonishment, the exact keyword was trademarked under class 016. I got really frustrated as I did all the hard work to create the book interior, book cover, and book metadata and now I was in no position to publish this book.

However, the good thing that happened to me was, I saved myself from future frustration which was going to happen if I hadn’t checked my title for trademark infringement. 

Secondly, I also learned a lesson and that is to always check your kdp keywords for a possible trademark or copyright infringement before creating your kdp interiors!

In this post, I will be sharing with you the exact keyword that I found was trademarked word(s) and you are not allowed to use that to create any low or no content book. Otherwise, you can lose your kdp account!

Later in this post, I will also share the links for checking your title against trademark infringement in the US, UK, and Canada. So, stick around…

The keyword is “Habit Tracker” and it is a trademarked word/phrase under class 016 which represents a trademark for paper, cardboard, books, and similar products. Below are the search results from USPTO about the phrase “habit tracker”.

So, if you find any keyword or phrase that is trademarked under class 016, don’t try to use it for creating a paperback or hardcover book. And most importantly, do your trademark research beforehand.

KDP Trademark Checker Sites

Below are some useful links you can use to run your kdp keywords through the trademark databases in US, UK, and Canada.

# 1 – USPTO

USPTO (US Patent and Trademark Office) is an official site for doing trademark search for the US marketplace. This site is a bit hard to navigate, therefore I am going to share with you the direct link to the page. 

Just head on to: https://tmsearch.uspto.gov/bin/gate.exe?f=login&p_lang=english&p_d=trmk

And you will see this page;

On this page, click on the Basic Word Mark Search. This will lead you to the page below, where you can enter your keyword or phrase to run it through the database. After entering your keyword, you can select some filters like live or dead and the type of search phrase. I have selected The Exact Search Phrase. 

Upon hitting the “Submit Query” button, you will be presented with the results page as shown below;

Now you can click on one of the results to see further details. I have clicked on the 2nd result, and I can see that the exact keyword “habit tracker” is registered under class IC 016.

As you can see, the word habit tracker is a trademarked word or mark and I can’t use it as the title of my book. You can do the trademark search the same way and keep your kdp account safe.

# 2 – Trademarkia

Trademarkia is the largest free trademark search platform. It’s very easy to use, all you need is to open trademarkia.com and enter your keyword in the search box, and hit enter.
