For copyrightable works, the owner can place the
copyright designation – the “C in a circle” © - on her work from the moment the
work is created, and include the year and her name. For example: © 2017 Jane
Doe. A copyright notice can be used
whether or not the work is registered with the U.S. Copyright Office. The
notice is not required, but it puts the public on notice of her intent to claim
and enforce her copyright.
A trademark owner can always use the “TM” mark
on its goods and services, to put the public on notice of his intent to claim
and enforce his trademark rights. The “R in a circle” – ® - is reserved only
for federally registered trademarks. If you register your trademark with your state trademark registry, but not the USPTO, you
may only use the “TM” mark.
I always recommend using the appropriate symbols
as soon as you put your product to market. Whether you have registered them yet
or not, this gives the public notice that you have considered your intellectual property protections and are prepared to enforce them.
