Elliptic Curve cryptography is the most topical & impactful thing I'm |
13 |
aware of. |
14 |
|
15 |
RedHat have for many years stripped parts of it out of their OpenSSL & |
16 |
libgcrypt packages, and continue to do it with OpenSSL-3 [1] (I note |
17 |
that somebody has dropped these patches from Gentoo's openssl as of v3 |
18 |
and I intend to restore them). |
19 |
|
20 |
RedHat's legal team clearly know something there that they aren't |
21 |
disclosing the details of publicly, because the patches said the patents |
22 |
expire in 2020, but when I asked off-list if EC could be re-enabled |
23 |
based on the expiry dates in the files, they claimed that patent issues |
24 |
were still present, without giving any detail. |
25 |
|
26 |
Somebody else ALSO asked about the Brainpool EC curves specifically and |
27 |
similarly got nowhere [2]. |

I feel that generally software patents as an issue for FOSS became less |
33 |
common because of patent grant programs: grants existed to encourage |
34 |
broad adoption of newer ideas from patents. |

I have some more fields for patents to add, where I believe active |
44 |
patents DO still exist: |
45 |
|
46 |
5. Elliptic Curve cryptography |
47 |
6. "Quantum" cryptography |
48 |
7. 3D Printing |
49 |
8. DRM |
50 |
9. UAVs/Drones (also hits EAR/ITAR) |
51 |
10. Rocketry (also hits EAR/ITAR) |
52 |
|
53 |
Other past patent stuff touching open source: |
54 |
11. Model Trains (see JMRI vs Katzer) |
