is highly recommended that any search
be performed either by an intellectual
property attorney or a professional
search firm that specializes in trademark
searches. A trademark or service mark
search is performed prior to filing
a trademark or service mark application.
The search is performed to determine
the availability of a mark for identifying
the source of a product or service
you provide or intend to provide.
This type of search should include

registered with individual states,
and common law marks that are unregistered
at either the federal or state level.
Trademark watch reports can also be
performed to identify improper use
of a registered mark.

registered at the federal or state level)
