Title: Amiga Patents
Post by: amiman99 on September 30, 2011, 02:48:02 AM

I was just browsing US Patent website, punched in "blitter" and first patent was by Commodore-Amiga.

Could only read few pages, then I got lost :confused:
Any other patents?

I did a patent search on Commodore in 2009 Amiga Inc AGA patents? (http://www.amiga.org/forums/showthread.php?t=41249)

Apple tries GUI patents in 2010 Apple Awarded Patent on The Dock (http://www.amiga.org/forums/showthread.php?t=47549)

So for FPGA Arcade and similar projects (A1200 - 1992):
 * 1984 CPU: Motorola 68020
 * 1985 I/O: MOS 8520
 * 1985 Sound: Paula
 * 1992 Graphics: AGA, Alice, Lisa

The other feature chipsets are Ranger (1987), AAA (1992), Hombre (1993). So any project involving the Hombre chipset may have to lookout. And ROM/floppy stuff is still in copyright.
(AA+ = paper product)

Spare parts list (http://www.amiga-stuff.com/hardware/index.html), A1200 tech (http://www.ianstedman.co.uk/downloads/A1200FuncSpec.txt)

Patent expire in USA (http://en.wikipedia.org/wiki/Term_of_patent_in_the_United_States)

In essence: Any patents that may exist, expires in 2012
