DavidEric Lengyel has released his patent over his rendering fonts directly from Bézier curves on the GPU into public domain.

A Decade of Slug
Hacker 
@DBG3D @sybren @blenderdevelopers "I was granted a patent for the Slug algorithm in 2019, and I legally have exclusive rights to it until the year 2038. But I think that’s too long."
"The patent has already served its purpose well, and I believe that holding on to it any longer benefits nobody."
"Therefore, effective today, I am permanently and irrevocably dedicating the Slug patent to the public domain."
"That means anybody can freely implement the Slug algorithm from this day forward without a license for whatever purpose they want, and they don’t need to worry about infringing upon any intellectual property rights. (For any legal experts reading this, my company has filed form SB/43 with the USPTO and paid the fee to disclaim the terminal part of the term for patent #10,373,352, effective March 17, 2026.)"
@Fedihacker ¿Your point? 🤔
Sybren A. Stüvel@DBG3D @blenderdevelopers @Fedihacker that's such a nice gesture!
I'm not doing anything with the GPU myself though. Maybe @atmind could use this?
