What can you do in a situation when people have similar ideas?
I have a shop on a site that allows you to sell t-shirts and things with your own designs. After noticing a problem I emailed them and they told me they have "received notice from [name removed] stating that the use of the [design name removed] design infringes upon her intellectual property rights". It stated the design/site name specifically. The problem is, I am not using this woman's design, nor was it taken from her concept as I did not know hers even existed and I created mine over two and a half years ago. I don't even advertise, tout it, or call it by any name similar to hers. Her website where she sells items with her design is new this year, so I assume the design may be as well, so I likely have had mine designed and offered to the public longer.
The site that hosts my shop has made this image/file so I can not use it. Because of this, no items are displayed to the public and it is now virtually non existent. I feel I have been screwed over. I have had my design long enough, I could probably claim infringement just as well... Though I have no problem in someone having a similar design to mine, as long as they aren't actually using mine. I don't understand why she should have the upper hand.
Though similar concepts, and BOTH inspired by another well known design (but different enough), my design is not hers and uniquely my own. And we are likely not the only people to have ever come up with this idea. I'll keep it basic, but it is a silhouetted figure. Surely she can not claim infringement on every silhouette of this type that is at all similar in design concept? Despite the concept, the two designs are still easily recognizable as different.
I have emailed my shop's host and they gave me contact information for this woman so I have also sent her a polite note explaining things and that no infringement has been intended, and my design is my own. I am not sure where to go from here... What can I do? I don't want to lose my unique concept as my own just because she may not like there being a similar concept by someone else.
I apologize if this has been long, thank you in advance for any advice.
