Jefferson was, of course, an inventor himself, though not as prolific of one as Benjamin Franklin, who also opposed patents.
"An act of Congress authorising the issuing patents for new discoveries has given a spring to invention beyond my conception. Being an instrument in granting the patents, I am acquainted with their discoveries. Many of them indeed are trifling, but there are some of great consequence which have been proved by practice, and others which if they stand the same proof will produce great effect." - Jefferson to Benjamin Vaughan, June 27 1790 [2]

(It's worth following the links in the letters above to see the story unfold.)
Now, here's where it gets interesting: Evans asserted his patent against Jefferson, and Jefferson did grudgingly pay royalties [4].
It's interesting how the passage years and being at the receiving end of a patent changes one's perspective [5].

[4] "He enforced that patent against many mill operators, including Jefferson. From this experience, Jefferson understood the frustration of technology users confronted by activist patent holders. Ironically, it was his Board of Arts that granted Evans the patent." - http://www.hssonline.org/publications/Newsletter2009/July_Ma...
[5] "Jefferson's objections to the Evans patent are difficult to reconcile with the fact that his Board of Arts granted the patent in the first place. As much as he might argue, in 1813, that the Evans work was not novel, he and his colleagues had reviewed the Evans work in 1790 and considered it worthy of a patent at that time." - Jefferson Vs. the Patent Trolls: A Populist Vision of Intellectual Property Rights, Jeffrey H.
