Does this mean that OpenCV will be able to now include SIFT in the “free” modules. Or are there more roadblocks before including it?

- rsp1984 7y agoI'm not a lawyer, but as far as I know expired US patents enter the public domain. After their expiration the described invention can be freely used by anyone for any purpose [1]. So I think the answers to your questions are yes and no.

- amelius 7y agoPerhaps there are still patents in other regions (?)
- dr_zoidberg 7y agoAs others commented, the only countries where software patents work are the US and Japan. So it'd be just Japan that could have a patent in place? Don't know theh details, and IANAL. OTOH, I'd really like the patent to be inactive, it'd allow me to work worry free in a lot of things that I've had an interest in.
- abhgh 7y agoI really hope so. Including SIFT in OpenCV should be easy since they did have an implementation earlier, which they removed due to the licensing.
