Patent numbers

Post by ob1 » Wed Mar 25, 2009 1:27 pm

Reading viewtopic.php?p=8305#8305, I've wandered a bit around Google Patent which is a great piece of ... curiousity (I wouldn't talk about knowledge).
Anyway, here it is :
TMS9918 4243984
Sonic2 5513307
32X 5692162
Massive 32X 5471579
3DO 5596693
SuperFX 5357604
Saturn 5816921

There are also some patents regarding Comix Zone, which describes the technique used to create the comics look. I can't find it right now, but I've seen it in the past.

It's very interresting because it seems you would get the source of this game if you bought the patent.

Edit: Patent number: 6010405

Menacer:

Video Display Processors:

US4243984 (patent of the TMS9918/28, which SMS & Genesis VDP are derivated from, some interesting stuff about how sprites are processed).
US5793351 (patent of the TMS9918 successor, codename "AVDP", which was never released by TI but supposely "inspired" Yamaha for the design of Sega VDPs)

For the record, the Sonic 2 patent listed above has some details about the Genesis VDP internal design.

Getting the patent with pat2pdf does't give me any of the game's source code... unless it's not giving me the full patent?

Software patents NEVER EVER give source code. At most, you'll see tiny snippets of pseudo-code. More usually, you get a few equations of math behind the algorithm, some hand waving on how that is done on a computer, and a general block diagram of the system it runs on. It's my major complaint about 99.9999% of software patents - there's no disclosure in a usable form. To be patentable, a patent is SUPPOSED to describe the invention in sufficient detail as to allow someone with average skills in the area to replicate the invention. Since lawyers have gotten involved, that detail has been tossed out.
