There's a thin line between copying and "inspiration", but there's a big difference between copying/inspiration and ripping. Ripped skins are easy to spot, they're just copy/paste jobs. Copying and inspiration on the other hand are a bit more subjective. For what it's worth, I can name at least 3 big-name IPB skinners/designers/whateva-ya-wanna-call-em who sell skins that are very, very clearly inspired by other skins. One has released skins that are clearly based off Neowin and whirlpool.net.au. Another released a skin that's very heavily inspired by XenForo's default theme. And another attempts to emulate SkinByDragonfly's style in all of their skins. These aren't no-name designers that I'm talking about either, they're some of the most well known IPB skinners out there. What they do isn't ripping, they don't copy code from others, but they do copy the basic look-and-feel. Yaldaram appears to have started as an attempt to emulate XenForo's theme, but they ultimately crossed the line into blatant ripping. Obviously they'd likely lose if it went to court, but had they just been "inspired" by XenForo's theme then they may have actually been in the clear. The real question that needs to be asked here is when do HTML and CSS become unique to the point that one can successfully claim ownership in court? There's really quite a big difference between using this... Code: <span itemtype="http://data-vocabulary.org/Breadcrumb" itemscope="itemscope" class="crust"> and using something like this... Code: <span class="item"> So, where is the line if you don't blatantly rip things like Yaldaram pretty clearly did? Like Jacquii said a few posts back, that's something that really has to be decided in court.
