Why Search?

Trademark searches can satisfy many needs.  The most common reason for conducting a trademark search is to determine whether a "likelihood of confusion" exists.  Has a mark already been registered that is:

  1. the same or similar to your mark
  2. used on related products or for related services

Trademark searches can also be a part of researching a company as they can show how many marks the company holds.  A search can also reveal more about an individual mark.
