The US Patent and Trademark Office (USPTO) announced that Certificates of Registration for federally-registered trademarks and service marks will change to a new format beginning this month.  The new certificate will be printed on stock white paper in either black and white or color, as appropriate.  The certificate will still carry the gold foil seal of the office.  The redesign is intended to reduce costs associated with the non-standard shape and paper type of the current certificate folder.  You can look at samples of the redesigned USPTO Certificates of Registration for trademarks and service marks here.
