CED VideoDisc and Player Discussion

[lynx]

I have found a problem with the cedmagic.com web site.



I have been reading the web site to learn more about CED, and I found the page in the CED Museum called CED Patents Table, with a very long list of patents for the video disc system. It looks very fascinating, and I would really like to learn more information about the patents, but the problem is that none of the links to the patents, listed on both the Patent No. & the USPTO column work. I have clicked on a lot of them, and the only thing that happens is that my computer says "Loading", with a blank white screen, and then it says "This site can't be reached." Is there any way to fix this problem? I would really like to learn more about all of the CED patents.



I have also been reading the old CED Digest messages from several years ago, which are very interesting. Are any of the people who were on that mailing list still collecting CEDs today, or are any of them on this forum? I am just curious.

The first column of the table that originally linked to Delphion has been fixed. The Delphion Network itself is long gone - their business model collapsed when the Patent and Trademark Office got its own website. So those links now go to Wayback Machine (archive.org) which archived delphion.com during the years it was an active domain.

Wayback Machine is handy, as the half life of a URL on the Internet is only about two years (link rot). Copying a link that doesn't work, and pasting it into the search box at archive.org will likely bring up archived captures of the original page. The link can be copied by picking copy link in the menu that appears with a control-click, right-click, or touch-and-hold on the broken link.

If the Delphion patent page looks interesting, more details can be found by copying the patent number and pasting it into one of the search options available at uspto.gov. Linking directly to patents at USPTO will be time consuming due to the complex URLs that contain HTML entities.
