text: is there any good patent lawyer? which can be paid at the end.? i'd like to patent my product but i have little money right now. many patent attorneys figure that if an idea is likely to be be successful that investors (who are better at predicting success of new ideas) will back the idea and fund the patent.    that being said, you may be able to find a patent attorney who would be willing to take legal fees on contingency, for share of company, future royalties, etc.  however, i'd be willing to bet that they'd require you to pay the filing fees, etc.  fronting legal services is one thing, paying money out of pocket is another.  a good place to start is posting on craigslist that you are looking for an attorney to take on a deferred payment arrangement.  good luck.
