USPTO Likelihood of Confusion Search Principles

(From TESS Online Help)


Following are the likelihood of confusion search principles used by the USPTO that you may want to consider prior to submitting a trademark application. You must decide which of these search principles may be appropriate for your trademark search. Even if you diligently follow all these search principles, that does not necessarily guarantee that you will find all potential citations under Section 2(d) of the Trademark Act.


  1.     Conduct a Thorough Search.
  2.     Search All Forms of all the Distinctive Elements of the Mark.
  3.     Search Each Distinctive Element Alone.
  4.     Search Acronyms AND What They Stand For.
  5.     Search All the Legal Word Equivalents of Terms.
  6.     Search Component Parts of Individual Terms When Necessary.
  7.     Searches for Marks Consisting of Two or More Separate Terms Should be Conducted so that the Two Terms Would be Retrieved Whether They Run Together or are Separate.
  8.     Search Pictorial Equivalents for Distinctive Terms and Vice Versa When Appropriate.
  9.     Search all Phonetic Equivalents
  10.     Search all English Equivalents


Plan for a Successful, Strong Trademark

(Not Just Avoiding a Likelihood of Confusion)


A Plan For a Strong Trademark is one that looks ahead to issues like:


These are all good questions to consider before adopting a trademark for use because if you are planning to succeed, it may be a good idea to be able to work that plan rather than abandoning it. The abandonment rate of trademark applications at the USPTO (trademarks that did not issue) is very high, about 40-50% of applications never register.

All of the above questions involve fact-related answers. Knowing the rules is really important, being able to apply the rules to facts is even better.


To prepare for a strong trademark, Not Just Patents® starts with these five steps:


1) Verify Inherent Strength (this avoids merely descriptive, geographically descriptive, likelihood of confusion and other office actions). If a mark is not inherently strong as is, are there additions to the mark or changes to make it stronger?

2) Verify Right to Use, (this avoids likelihood of confusion refusal office actions and others)

3) Verify Right to Register, (this avoids many types of refusals including merely descriptive, deceptively misdescriptive, geographically descriptive and others that can often be predicted)

 4) Verify the potential mark (as currently used) Functions As A Mark, and (this avoids specimens refusals, trade name refusals, and others. The USPTO is looking for valid use not just any use of a mark.)

5) Verify that the Goods and Services ID is both the correct and the maximum claim that are user can make and verify that the Goods and Services ID meets USPTO requirements before filing. (This avoids office actions to correct incorrect IDs  which can slow down a registration. Incorrect IDs  may be corrected during the prosecution of a trademark if they do not materially alter the mark or the ID. Correcting problems before application saves time and money. Filing in a new class after an application has been submitted to cure a problem ID is the same price as a new application in that class.)
