I'm not an expert on this topic, but much of the information in the first paragraph seems outdated. The European Community was replaced by the European Union, and Hungary is an EU member.Josef Horáček (talk) 21:47, 9 April 2012 (UTC)
I made one small correction to the photo caption for the Coca-Cola bottle patent. The correct patent number is D48160, not 48160. The "D" indicates a design patent, as opposed to a new machine, or method of manufacturing. Without the "D", U.S. patent 48160 refers to something called a "Mode for Making Corundum Wheels", patented on June 13, 1865. Elsquared (talk) 08:12, 30 May 2009 (UTC)
A citation is needed for the notion that the coca-cola bottle is still protected by trade dress after expiration of the design patent. There is a substantial question as to whether that is the case, because expiration of the design patent should allow anyone to practice it (as a matter of constitutional law) and allowing trade dress protection thereafter is akin to an extension of the patent rights after expiration. http://www.inta.org/TMR/Documents/Volume%2094/vol94_no5_a5.pdf— Preceding unsigned comment added by 188.8.131.52 (talk) 14:54, 13 June 2011 (UTC)
