Famous quotes containing the words patent and/or claim:
“There is a patent office at the seat of government of the universe, whose managers are as much interested in the dispersion of seeds as anybody at Washington can be, and their operations are infinitely more extensive and regular.”
—Henry David Thoreau (1817–1862)
“Such is the confidence that we have through Christ toward God. Not that we are competent of ourselves to claim anything as coming from us; our competence is from God, who has made us competent to be ministers of a new covenant, not of letter but of spirit; for the letter kills, but the Spirit gives life.”
—Bible: New Testament, 2 Corinthians 3:4-6.
