To be honest, I don't believe that any of this is actually IP or copyright theft.
I think too much has been made in SL of the ability to protect "copyright" and "IP".
When I walk around SL, I see a lot of beautiful digital craftmanship, I see very little original design.
I appreciate that migrating an idea or design from RL to SL takes a lot of time and commitment however, unfair as it may be, hard work and effort is not a measure of originality.
All I can say is (and to paraphrase Alan Sugar) in my role as owner of a small software business I've written books on copyright and IP law... cheque books

lol.. ok that's overstating it a wee bit, but I've spent a fair bit of money and to be honest don't feel any more secure from piracy or IP theft than I did before.
It's just not simple to identify what can and can't be protected because it's not simple to identify where the originality is in any design or piece of work.
Also to be honest, most of what I see in SL are digitized versions of designs and ideas which are actually copyright and IP theft from RL designers.
As an example, taking an image or idea from your favourite RL shirt, digitizing it and uploading a virtual version into SL might be hard work, but doesn't entitle you to any protection. In fact it might be said that you, yourself are guilty of some infringement.
I'm not against protection of ideas and original creativity, as I've tried to show.. I've been frustrated in RL by the law as it stands at present.. particularly in the digital media and software arenas.
Finally I'd like to draw a distinction between protection of creativity and trademarks/brands.
I've seen many copies of Nike trainers passed off as original design in SL, however what you don't see much of is the Nike logo.
So perhaps the best idea is to build a brand which is distinctive and original, this is more easily protected and in all honesty a creative exercise in itself.
At the end of the day we'd probably all sleep better in our beds if we took Coco Chanel's view that imitation reflects the highest form of flattery..

Damn, you're good.
More or less you said some of the same things I did but you said in a nice way whereas, I didn't due to fact I like being blunt and crass at times just to get my point across really quick. Especially when doing it in here.
Some of these people have "stolen" themselves in the products they sell as they're not affiliated with the brand names they tend to use in selling their stuff either. Then they'll be the first to turn around and complain about theft of their wares. Tsk, tsk, shame, shame.
Unbelievable!
I had to come back. I'm thinking "sticky" for Stephen's post so next time they want to complain about theft or whenever their self delusions and paranoia begins to kick in they can come and take a peek to soothe their senses.
