Early last year I implemented several new and unique features on Neocamera and most have been copied by DPReview.
They announced the latest one this morning. It is called 'My Short List' there while on Neocamera, it is called 'Camera Bag' which I explained in a blog post last September. They had a vague announcement in March for the previously copied features, which I had also since last September, basically search engines for cameras and lenses by features or specifications.
It is obvious that those are the same features but they are presented differently. So this is not a case of design or style being copied, only the capabilities. Once you look at them, you see that there is an uncanny overlap in functionality.
Can something be done about it? In case it matters, my site is based in Canada while theirs is registered in the UK. It belongs to Amazon, not sure which corporate entity.
