There's a patent battle brewing between Capcom and Koei Tecmo
There's a patent battle brewing between Capcom and Koei Tecmo
August 26, 2014 | By Alex Wawro




Osaka-based Capcom has filed a lawsuit against Koei Tecmo Games in Osaka District Court seeking roughly 980 million Japanese yen (~$9.4 million USD) for patent infringement, according to a report from the Japanese news outlet Sankei interpreted by Siliconera.

Capcom seems to be alleging that Koei Tecmo has published a number of games, including multiple titles in the Dynasty Warriors and Samurai Warrios franchises, which infringe on a 2002 Capcom patent governing how a company distributes additional content to people who own one of its games.

The full details of the patent in question are yet unclear, but it's likely that Capcom is referring to the disc-based expansion packs available for some Koei Tecmo PlayStation titles.

Capcom claims Koei Tecmo earned roughly 97 billion Japanese yen in profits on sales of infringing titles, and it seeks damages commensurate with the fees it believes Koei Tecmo should have paid to license the technology as well as a suspension on further sales of select Koei Tecmo games.

"The full details of the patent in question are yet unclear, but it's likely that Capcom is referring to the disc-based expansion packs available for some Koei Tecmo PlayStation titles."

If this is true, how is this different from multi-disc games from that same era? If it makes sense to use the same save file for multiple discs in a single game, why would it not be obvious to a game developer to do the same for multiple game releases?

As I think more about this, this does not make sense:

"which infringe on a 2002 Capcom patent governing how a company distributes additional content to people who own one of its games. "

How did the application not get denied when Baldur's Gate 2 and other games predate it that year?

The only thing I can think of with the dynasty warriors games is the use of a save file from a previous game to unlock features of a future game, such as (iirc) being able to use a save file from dynasty warriors X to unlock features from dynasty warriors X Empires, or Dynasty Warriors X Xtreme legends. So I can only assume the patent has to do with that, in which case I'm certain there were games on the PC and such which predate it with the same / similar functionality.

I was going to point out Legend of Zelda Oracle of Seasons and Oracle of Ages as something that predates this patent, but those are Capcom games and came out a year before the patent. So they could be a part of the basis Capcom claims for this patent. In those games, beating one unlocks content on the other if you link them up. But even that is predated by Pokemon's trading system, which is functionally the same thing.

Hypocrisy never seems to deter creativity predators like CAPCOM, Zynga and King. CAPCOM was preying on indie and unknown games before it was "cool".
