First off, great and inspiring site!

I've read a lot of topics on submitting prior art for patent applications. Does the same rules apply for already issued patents? I could just save the prior art and wait for the lawsuit, but i'd rather take a proactive stand :)

Sure, part of the patent process is the ability to challenge existing patents. From the FAQ:

Ask Patents - Stack Exchange is a collaboratively edited Q&A platform for patent experts, inventors and citizens who wish to participate in the US patent process. Its primary purpose is to help individuals:

1. Solicit help finding prior art that might apply to a patent or application
2. Get answers to hard questions about specific patents
3. Ask questions about the US patent system or process
