The Open Software License (OSL) is a software license created by Lawrence Rosen. The Open Source Initiative (OSI) has certified it as an open-source license, but the Debian project judged version 1.1 to be incompatible with the DFSG. The OSL is a copyleft license, with a termination clause triggered by filing a lawsuit alleging patent infringement.
Many people in the free software / open-source community feel that software patents are harmful to software, and are particularly harmful to open-source software. The OSL attempts to counteract that by creating a pool of software which a user can use if that user does not harm it by attacking it with a patent lawsuit.

Famous quotes containing the words open and/or license:
“The child ... stands upon a place apart, a little spectator of the world, before whom men and women come and go, events fall out, years open their slow story and are noted or let go as his mood chances to serve them. The play touches him not. He but looks on, thinks his own thought, and turns away, not even expecting his cue to enter the plot and speak. He waits,—he knows not for what.”
—Woodrow Wilson (1856–1924)
“It is a misfortune that necessity has induced men to accord greater license to this formidable engine, in order to obtain liberty, than can be borne with less important objects in view; for the press, like fire, is an excellent servant, but a terrible master.”
—James Fenimore Cooper (1789–1851)
