ANALOGOUS USE

analogous  use.  1.Patents. The application  of  a  process already  known  in  one  field  of  art to

produce a similar result in another field. • Unless the  fields are so  unrelated  or the  outcomes so

different as to produce a novel, useful, and nonobvious result, an analogous use is not patentable.

2.Trademarks.  The  use  of  a  mark  in  marketing  and  advertising  a  product  or  service  before  the

actual sale of the product or service, in order to establish the  mark’s use in commerce. • For the

owner  to  take  advantage  of  the  analogous-use  doctrine,  the  marketing  campaign  must  be

substantial and the product or service must be available soon after the campaign. An owner who

files an in-tent-to-use application may tack on the period of analogous use for purposes of priority

and incontestability. [Blacks Law 8th]
