Suppose you have an idea that you know will sell well but depends on a third party, a more established organisation.
A good example is back in the days when SMS-based services were very new. Suppose you have an idea relying on SMS. Like allowing stock market quotes to be received by people via SMS on an adhoc basis. For each request, you get a fraction of the SMS cost. Suppose that market is very big and that service has never been explored....BUT you have the idea to implement it. You, the freelance designer with no dedicated staff and working from a home office, would like to approach, say, the Business Development manager of an Cellular Service provider with this idea. I assume they will demand a proposal with financial projections/ pro forma, a brief on how it will work etc.
How do you prevent yourself from being muscled out? They could easily take up the idea and implement it? At this point, do you have legal right over the idea? I understand there is no protection against ideas. (laws protect inventions with patents, creative works with copyright, and trade names with trademarks,) It would also be understandable if the company does not work with restrictive NDAs that would eliminate any future, similar ideas and also make them vulnerable to litigation.
Whats the best approach?
