what type of patent regime is followed in u.s?

Answer 1

I'm not too sure what you mean by regime but I posted some information about the patent process in the US.

NOLO is a great, free informational site. Also, be sure to read what the USPTO (United States Patent & Trademark Office) has to say about patents.

Associations may be a good avenue to explore. These organizations will address many of the thoughts, questions and concerns you'll inevitably have as well as many you haven't anticipated yet. See the source box for some relevant links.

There are plenty of free informational resources out there. Check the source box for links to articles.

Hope that helps! I wish you much success & happiness in all your ventures!
