I've enjoyed reading the comments from the armchair intellecutal property attorneys on TCDB! It's a topic that there's enough general awareness about but what's actually legal versus copyright infringement is complex and varies on a case-by-case basis. I studied intellectual property in law school (took several classes) and being a IP lawyer was one of my career options. I never practiced IP law, but I've always been interested in it.
It's frustrating that someone used the images of cards that you posted on TCDB. But once you posted that image on TCDB and the internet, it basically became fair game for others to use. The card companies own the copyrights to the card images. If you somehow altered the image to provide enough creative difference to be meaningfully different, then you would could have a copyright to that artistically revised image. But that's not what we're doing here on TCDB. Topps and Panini aren't going to sue you, though because it's not worth their trouble and it's likely you do have a fair use exemption since you are not trying to profit off the image itself or diminish the market value of their cards. You are merely providing the image to TCDB for archival and information purposes. If you tried to sell images of the card, especially as an alternative to the actual card, you would risk copyright infringement.
The case for TCDB as a compiler of all those images is a little further down the slope, but since the site serves the function as an archivist and information resource, there's a strong basis for concluding TCDB's use of the images is also a fair use. And again, TCDB is not selling the images nor diminishing the value of the card companies versions of the cards.
BuySportsCards.com is not selling the stock images of the cards or counterfiet copies of the cards, so they are not profiting from the card company's copyrighted works either. They are using the images to archive and illustrate cards, much like TCDB does. Just because they are a for-profit entity doesn't mean their archiving of the checklists and images is any less of a fair use than what TCDB does. The Beckett Marketplace does the same thing.
The fair use exemption frequently looks at how the usage diminishes the copyright value of the copyright owner's economic value of its copyrighted works. It would be difficult for Topps or Panini to argue the economic value of their copyright on individual cards is diminished by this web site's usage of images of their cards. If anything, it embellishes the market value of their products by providing another means to promote the liquidity of trading cards.
I think we'd need to understand how BuySportsCards.com extracted data from TCDB to understand whether there was actual copyright infringement of TCDB's intellectual property. TCDB's data and structure and mechanism for compiling/displaying the data form the basis for TCDB's intellectual property. That would be the most likely avenue for TCDB to claim copyright infringement. It's been too long since I studied IP law for me to know where the law stands on this aspect of intellectual property protection.
Beckett crushing Zistle and other similar web sites probably had less to do with actual copyright infringement than the threat of fighting Beckett about possible copyright infringement. Those web sites were basically hobbyists who put in a lot of time building their sites. Maybe they copied stuff from Beckett. I don't know. But when a big company threatens an Average Joe with litigation, Average Joe is most likely just going to stop - even if they weren't actually violating copyright law. In Zistle's case, Beckett paid the original developers some money as a way of getting them to stop their web site. That says to me that Beckett wasn't 100% confident they'd win in court, so they made an economic decision to pay Zistle to die instead of paying their lawyers to litigate. The people at Zistle made an economic decision to take Beckett's money instead of paying lawyers to fight. (By the way, someone recently attemped to get Zistle going again, but it's now dead again.)
I really hope Admin posts at some point how this situation is being handled. I'd really like to understand what IP principles were at play here.
Finally, I'd like to see a site like BuySportsCards.com succeed. Maybe not them if they infringed TCDB's IP. It seems like a good idea and it's better organized/easier to use than SportLots. It, or something like it, has the potential to be a good site for buyers and sellers. We need better alternatives to eBay and SportLots for low-mid value cards.
