There were also software patents long before that. Samuel F. B. Morse
got US Patent 1647 in 1840 for the Morse Code. Its reissued version

Claim 5. The system of signs consisting of dots and spaces, and of dots,
spaces, and horizontal lines, for numerals, letters, words, or sentences,
substantially as herein set forth and illustrated, in combination with
machinery for recording them, as signals for telegraphic purposes.

The US Supreme Court upheld that claim in 1853.

You can also read Morse's original claims here.
