Reviews of The 3 Best Trademark Clearance Search Tools for Trademark Attorneys

Nick Potts,

Conducting a trademark clearance search has never been more important.

In today's world of global commerce, competition is no longer limited to your backyard. The Internet has opened up both national and international borders in ways our predecessors could have hardly imagined.

The number of trademarks registered each year is staggering. The United States Patent and Trademark Office has seen a 6.9 percent increase in registrations in 2016, translating to about 398,000 applications.
Factor in trademarks registered in jurisdictions around the world and you have well over a million! Because of this, the trademark clearance process is becoming increasingly complex.

The Best Trademark Search Tools

While free databases like USPTO, TESS, WIPO, and EUIPO have accurate information, they don't provide enough intelligence to thoroughly assess risks from all angles. This is where trademark search service tools and providers come into play.

In this article, we'll review the top three providers that clearly stand above the rest. Generally speaking, trademark clearance tools fall into two categories: Human-powered and Technology Assisted.

1. Human-Powered Search Strategy

With this route, an expert is mining databases, organizing information, and manually creating a comprehensive risk assessment on your behalf. Additionally, they will tap into their expertise to come up with as many different permutations of your chosen trademark as they can think of.

Using a "substitute this for that" methodology, they'll analyze words for visual and phonetic similarity. This is extremely important. After all, you don't want your client to get sued by Nike for marketing the trademark phrase, "Must do it!"

Human-Powered Provider Options

When it comes to expert-powered search, there are two reputable companies to consider: Corsearch and Thompson CompuMark. Both companies offer similar, high-quality services.

1. Corsearch

Corsearch has more than 60 years of experience in the trademark community. The organization provides full searches by country and region, as well as a worldwide search conducted by trained researchers who review thousands of potential results. Online sources, periodicals, databases, directories, books, and proprietary databases are all consulted to provide comprehensive marketplace overviews.

Once the search is completed, the information is organized according to relevance. With Corsearch, you have two options: You can pay a la carte or purchase a package. Here are some of their most popular options:

2. Thomson CompuMark

Thomson CompuMark, a business unit of Thomson Reuters, provides a broad range of trademark research and brand protection solutions. Currently the largest trademark service provider, the organization employs more than 55,000 people in more than 100 countries.

It should be noted that Thompson Reuters recently sold its Intellectual Property & Science division to Onex Corp. and Baring Private Equity Asia for $3.55 billion in cash. The media company said in a statement that it would use $1 billion of the proceeds to reduce debt and buy back stock.

As of the time of this writing, the changeover hasn't affected the company's standard offerings. Thompson CompuMark provides U.S. full search offerings includes coverage of identical marks in all classes, plus confusingly similar marks in classes relevant to your product or service. Similar to Corsearch, the trademark clearance search process is conducted by a team of researchers.

Both companies take thorough steps (i.e. reviewing search strategies, checking USPTO database records for accuracy) to provide quality results. And both offer a variety of search packages, including (but not limited to):

  • Cross-Market Search
  • European Comprehensive Search
  • U.S. Comprehensive Search
  • E.U. Member State Options
  • Web Common Law Search
  • U.S. Company Name Search

Pros and Cons of Human-Powered Search Strategy

  • Done For You: With an outsourced expert search, you can spend more time working on income-generating activities.
  • Peace of Mind: Hiring a reputable search company can reduce your risk of human error.
  • Comprehensive Coverage: Thomson covers more than 192 regions (the largest breadth in the marketplace), while Corsearch covers nearly as many.
  • Large Common Law Source: Thomson boasts the largest common law source on the market. However, it should be noted that approximately 40 percent of those sources no longer exist and are old repositories.


  • Slow: Since search strategies are conducted by actual humans, you'll have to wait a few days for your report. Manual search clearances average 3 to 5 days.
  • No Ranking of Results: Unfortunately, your search results won't be returned to you in order of highest threat to lowest. Expect a lot of data mining.
  • No Guarantees: Reviewing thousands of search results leaves room for human error. Foreign languages, connotations, and cultural implications can all easily be overlooked.
  • Expensive: It's important to remember you're paying for a professional's time and expertise. Though prices vary, they generally fall into these averages: $1,500 for a full U.S. search, $8,900 for a full European search, and $40,000 a worldwide search—and that's just for one category.

While issuing an expert-led search is often more comprehensive than delegating to paralegals, it obviously has some drawbacks, the primary one being cost.

If, for whatever reason, your client needs to search outside of the parameters originally agreed upon, or outside of some pre-agreed searching limit, he or she will be charged per result. That can cost anywhere from 50 cents to $2 per entry. The problem? You really don't know how many results you're going to have until you search. If you receive 1,000 search results at $2 per entry, that's an extra $2,000.

Technology Assisted Search Strategy

Thanks to recent advances in technology, trademark attorneys now have the option of DIY search options.

Although both Thomson and Corsearch provide online tools, these are largely "data pulls" that can be used to retrieve copious amounts of information that still need to be sifted through manually. In other words, a human being still needs to spend countless hours analyzing the results, ranking them and ultimately, highlighting the most concerning marks. For this reason, these options don't fit into the technology assisted search category.

In contrast, a technology assisted program can yield a number of specified search queries before delivering ranked and relevant results generated by scientific algorithms. TrademarkNow is currently the only provider on the market to offer this technology.


TrademarkNow brought together some of the brightest minds in the software and legal industries to develop something different: An artificial intelligence program designed to instantly evaluate word linguistics, product types, and jurisdictions—in seconds.

Basically, the NameCheck system completes the same quality of clearance search conducted by a human being in as little as 15 seconds. For due diligence, the results should be reviewed for a final risk assessment by a Trademark lawyer. But, the results, and speed of search will make their job much easier, and cut out days or weeks of waiting and work.

The major benefit? Unlimited search options for one flat rate.


  • Unlimited global search
  • App store data common law source
  • All class and product categories
  • Phonetic and visual similarity of proposed mark words
  • Semantic distances between product classes
  • International/Global word meaning
  • Internet domain registrations
  • Unregistered marks used in commerce
  • Unregistered products/services in active commerce

Pros and Cons of Technology Assisted Search Strategy

  • Control: The trademark search process is 100 percent in your control.
  • Immediacy: Obtain search results in less than 15 seconds.
  • Relevancy: Review ranked results of potential candidates.
  • Affordability: Suitable pricing (with flat rates available in many cases).
  • Peace of Mind: A scientific algorithm that eliminates human oversights.
  • Creatively Supportive: Search as many names as you want.
  • Design Search Function: With LogoCheck.
  • Fewer Regions: While nearly all regions will be covered soon, TrademarkNow currently covers 153 regions (including all major ones).
