3 years ago I invented an idea about creating special mobile application. However, I could not patent it due to high cost of. I participated in diffirent conferences and competitions with my idea to obtain funding for the last 2 years. However, several weeks ago, one huge US company got patent on exactly this idea. I am from Uzbekistan, though I have an evidence about my idea and participation in different programs with it, the application is only on idea stage. Can I claim on any IP issues? and what alse can be done?
If you can document that you presented the patented claims in public prior to the filing by the patent holder, your presentations can be used as prior art to invalidate their patent. This will likely require litigation. One of their competitors may offer compensation for your efforts.
If you have presented the material in any public forum you can no longer rightfully obtain an EU patent. If you presented over a year ago, you cannot rightfully obtain a US patent. But, by invalidating theirs, you will be free to market your own product without infringing on their rights.
