Class-Based and Keyword-Driven Comparative Research
ThorCheck is a great, unique tool for comparative research. The first iteration, and still the most commonly-used, helps you identify active, use-based registrations for the same mark for two different sets of goods, e.g. trailers and trucks. In re Thor Tech, Inc., 113 USPQ2d 1546 (TTAB 2015). It saves hours or even days of manual research, and has helped hundreds of applicants prevail over difficult related-goods refusals.
The original ThorCheck Goods and Services tool is still your best option for most goods/services comparative research, but was less adept at two kinds of searching.
The first was for class based comparisons – finding overlap between, say, a food in Class 29 or beverage in Class 32 and a restaurant service in Class 43, or between a pharmaceutical in Class 10 and a medical service provider in Class 44. Any evidence of that type of overlap is potentially valuable, and ThorCheck’s emphasis on individual goods or services didn’t allow for easy “general” comparisons like this.
The second was for highly varied goods and services, like software – give the same description of a hospital-focused SAAS to ten different trademark lawyers, you’ll get ten different descriptions of services.
The new Custom option solves both sets of problems.
Class-Based Comparisons
Setting up a custom search is easy – just pick one class in First Party Trademark Criteria and the other in Second Party Trademark Criteria. As always with ThorCheck, your results are limited to active, use-based registrations.

Exporting a summary chart and TSDR status and title copies is as easy as always; just tag relevant results and export to Word or Excel, or select up to 100 records to get TSDR status and title copies at a go.
What if you’re the senior party, and want evidence that cosmetics are related to more industrial chemicals? Just pick Class 1 and 3 respectively, and change the Evidence option to “Similarity,” as shown below.

Keyword-Driven Goods and Services Comparisons
Custom goods and services ThorCheck search strategies look a little more complicated, but they are conceptually simple: come up with two sets of search strategies that identify either different (Dissimilarity option) or overlapping (Similarity option) universes of marks. ThorCheck will put all the pieces together, lining up identical marks with either different owners (Dissimilarity option) or identical owners (Similarity option).
Let’s do an example. Say your client offers industrial software for running oil, gas, and mining operations. A prior registration for software in the HR space has been cited as a bar to registration, with the Examining Attorney taking the position that part of running industrial operations is dealing with HR issues. You plan to argue channels of trade and that the users of the software are different, but would love to have evidence to attack the relatedness of the goods directly. ThorCheck can provide it. We want to limit both First Party and Second Party criteria to Class 9 and 42. On the First Party Criteria, we want to pair software-related keywords with keywords like mining, oil, gas, and industrial. One the Second Party Criteria, we want to pair those same software keywords with either the phrase “human resources” or the term “HR.” The search strategy looks like this:

The results speak for themselves – dozens of examples of just this sort of overlap. A sampling of the representative results are attached, and it’s only a fraction of the evidence surfaced by ThorCheck.
