After graduation from law school, he went into private practice in his hometown of Marshall, Texas, and then moved on to public service a year later, serving as Assistant District Attorney for Harrison County, Texas and later District Attorney. He returned to private practice in Marshall, Texas in 1959 and remained there until his appointment to the CCPA in 1968 by Lyndon Baines Johnson.

Judge Baldwin was the author of "In re Moore" (444 F. 2d 572, 170 U.S.P.Q. (BNA) 260 (Fed. Cir. 1987)), a patent law case establishing the logical asymmetry of the "prior invention" standard between patent interference claims and Rule 131 affidavits.
