It's not really that big of a deal, because the infringed-upon have a much lower burden in any patent action, because their claims are in the patent. So discovery motions in an patent infringement are almost always targeted at the alleged infringer/defendant, not the plaintiff.
And if you are suing for patent infringement, you are going to be using a specialist legal team, who probably aren't local to you anyway, regardless of where you are located.
(E.g. the largest IP fight I was involved in was fought in a court in Salt Lake City, Utah, used San Francisco, CA attorneys, and the company's operational HQ was 400 miles south of their in Southern California.)
