Assume an inventor A has no patent, just published proof that he created the Invention. Assume a second individual B copies the Invention and files for a US patent on the Invention. Does A have any means of gaining financial compensation for his stolen design despite having no patent on the Invention?
Ask an attorney, especially if the patent holder is making tons of money from it. If it is a filed application rather than an issued patent, there are ways of bringing the published information to the examiner's attention to try to keep it from of being patented. If the person has gleaned information from you and added on to it, it is possible that legally you would be considered joint inventors. If you are legally joint inventors but you are not listed as an inventor, there are remedies for that. If he copied from you or just made an independent invention/discovery but you did it first and his patent is relatively new then you can file your own patent application and provoke an interference proceeding. In that expensive process you can attempt to prove you were first.
