Hi guys, first time using this forum and need some advice. If say for example, I develop a patent in 1993, and a drug company develops a new drug from my patent, and launch it in 2013, would i have a right to any of the proceeds even after the patent has expired? The drug company has spent the period between 1993 - 2012 developing the product using the patent, but only started commercializing and selling the product in 2013 (after the patent expired). The drug company did not approach the inventor for any type of sale/royalty stream during that time. Does the inventor have rights under intellectual property law? Thanks.
