This is a moderately complex issue, but one that can often be overcome.A substitute specimen or drawing will be requested if the Examining Attorney feels that the specimen ordrawing is not compliant with technical requirements, or if the specimen does not clearly show the applied-formark used in connection with the applied-for goods or services. Submitting a replacement drawing or specimen may remedy this issue. However, the replacement specimen must have been in use as of thetime that the original specimen was filed.
