Has anybody ever been involved with a copyright dispute involving PicRights and if yes, how did you handle it?

In the US, terms and conditions do not override the law of the land. Depending on the exact situation, and intent, I would suspect that an entity could make the case for fraud, trademark infringement, theft, or copyright violation. The practice will likely get you blacklisted by any search engine of significances, undercutting whatever your objective was in the first place.

This is a tricky question as you are entering a gray area if you are using material from Book Z to inspire your own book. Derivatives works are highly litigated and there is case law that you could turn to to help you make this decision but based on your example its going to be a fine line. You would have to be able to distinguish the products as two very separate works. Since the original book Z is inspiring your new book this may be hard to do. It might actually be easier to talk with the original author about your future plans and develop an agreement between the two of you where he waives any claims he might have here in exchange for recognition in your book. Just an idea--FYI- this is NOT LEGAL ADVICE. You should consult with an attorney in more detail here.

I have been working as a Business Entrepreneur and have been working with many of the customers from Europe, North America. While creating a White Label solution, the most important part for the owner is to manage the security for the product as well manage the Quality to be delivered within the expected timeline and budget. While choosing a company, the NDA's would work but with them you can also sign a Proposal, SLA(Service Level Agreement) which helps to bind the contract and source code as your own property. As when it comes to offshore development, my suggestions is to choose a company which has been doing this services since more than 5 years now and have been a part of good success stories whose stories are kept confidential. So with the documents, a formal trust would help you create the platform as your own property with the expected quality. You can consult your Legal adviser in the matter and hope they would align the strategy.

Disclaimer: I'm not an intellectual property attorney - and I am not attempting to, nor qualified to give legal advice. That said - here is what I know on the subject. Copyright was once explained to me as a bundle of sticks, where each stick was a different right. Two sticks that might be important in this situation would be: 1. Distribution Rights: Creating the sheet music in itself may be harmless, but copyright does cover right to distribute - and so your idea to distribute for profit may infringe upon this right. 2. Derivative Works: Copyright also gives the owner the right to create derivative works based on the original - so even if your version is different - it becomes an issue of "how different" - so you may also be infringing on this right. One path forward is to determine who owns these rights (the original artists or label often sell the rights) and license the right to produce and sell the sheet music. My guess is this could be cost and time prohibitive. Another would be to see who is already selling sheet music for these songs - and simply act as an affiliate, taking a portion of the revenues per sale. Consider trying the affiliate route first, to determine how many of these sales you generate from your audience, before going to the trouble of licensing the content etc. I'd be happy to discuss ways that you can validate demand within your population before you do either, and recommend doing so with or without my input.

Ries owns 'Lean Startup' trademark. I doubt 'lean' by itself is trademark-able, and isn't claimed by Eric. Someone else may claim 'lean career development,' so might be worth a trademark search.
