One of the responsibilities of the Director of the USPTO, carried out every Tuesday, is the signing of US patents and US trademark registration certificates. On Tuesday, January 19, 2021, Director Andrei Iancu’s signature was placed upon 5414 trademark registration certificates and 4605 patents. One of the trademark registration certificates appears at right, and I have highlighted his signature which appears just below the gold seal.
The following day, January 20, 2021, Mr. Iancu ceased to be the Director. Now the person performing the functions and duties of the Director is Drew Hershfeld, the Commissioner for Patents. I expect that this coming Tuesday, January 26, it will be Mr. Hirschfeld’s signature that will be placed upon the patents and the registration certificates.
