What type of agreement do I need to make sure I own my product's code and have full rights to amend and sell the business (incl. the code) later?

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.

I developed and published mobile apps as an individual for several years, and only formed a corporation later as things grew and it made sense. As far as Apple's App Store and Google Play are concerned, you can register as an individual developer without having a corporation. I'd be happy to help further over a call if you have any additional questions. Best of luck with your mobile app!

From a legal standpoint: an NDA is an agreement - something contractual, and therefore is not limited (by law) to any specific jurisdiction. So, you can select Delaware or California, or India for that matter. From the business aspect, the best jurisdiction to select would depend on: 1. Jurisdictions that are known to be 'friendly' to your type of business. 2. Jurisdictions in which your lawyer is licensed to practice / the cost of lawyers isn't too expensive. 3. Somewhere not to far from where you are physically located - in case you actually have to go to court. Lastly, best to add a required arbitration or mediation clause if you don't have one. Good luck

This sounds as a deja vu to me. I have been in a similar situation back in 2000, we could only solve the issue thanks to a good mediator. However every situation is different and hence your route to a solution might be different. It also depends where you are in the world that defines how an email and/or verbal agreement might be a sufficient ground for legal actions. I am not a lawyer and can not judge that.

I've discussed ideas with hundreds of startups, I've been involved in about a dozen startups, my business is at $1M+ revenue. The bad news is, there is no good way to protect ideas. The good news is, in the vast majority of cases you don't really need to. If you're talking to people about your idea, you could ask them to sign an NDA ("Non Disclosure Agreement"), but NDAs are notoriously hard to enforce, and a lot of experienced startup people wouldn't sign them. For example, if you asked me to sign an NDA before we discussed your Idea, I'd tell you "thanks, but no thanks". This is probably the right place though to give the FriendDA an honorable mention: http://friendda.org/. Generally, I'd like to encourage you to share your Ideas freely. Even though telling people an idea is not completely without risk, generally the rewards from open discussions greatly outweigh the risks. Most startups fail because they build something nobody wants. Talking to people early, especially people who are the intended users/customers for your idea can be a great way to protect yourself from that risk, which is considerably higher than the risk of someone taking off with your idea. Another general note, is that while ideas matter, I would generally advise you to get into startup for which you can generate a lot of value beyond the idea. One indicator for a good match between a founder and a startup is the answer to the question: "why is that founder uniquely positioned to execute the idea well". The best way to protect yourself from competition is to build a product that other people would have a hard time building, even if they had 'the idea'. These are usually startups which contain lots of hard challenges on the way from the idea to the business, and if you can convincingly explain why you can probably solve those challenges while others would have a hard time, you're on the right path. If you have any further questions, I'd be happy to set up a call. Good luck.
