Funny, the german wikipedia page says: Ferner wurde der Firma IBM ein Patent auf dasselbe Verfahren erteilt; dies beruht auf einem Fehler des US-Patentamts. Die Anmeldung erfolgte zwar drei Wochen vor der von Unisys; nach dem Patentrecht der USA bedeutet dies jedoch nicht, dass das IBM-Patent Priorität genießt. Vielmehr dürfte das IBM-Patent aufgrund des früher erteilten Unisys-Patents ungültig sein. Es würde am 11. August 2006 auslaufen. http://de.wikipedia.org/wiki/Graphics_Interchange_Format Pete - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I believe it is the US IBM patent that expires on 11 August 2006. /Per Jessen, Zürich - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Could you elaborate? At least the LZW patents, where the GIF format suffered from, expired in 2003/2004 IIRC.

I think the next/last GIF-related patent expires in a couple of weeks, so although PNG is probably superior, perhaps it doesn't matter much whether it's GIF or PNG? /Per Jessen, Zürich - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
