If these mysterious patents are about things like "virtual DOM", comparing trees of state or something derived from FRP, then using Vue, Preact, Angular 2, Cycle, Riot, Elm, reflex-dom is not more patent-safe. Moreover, they can sue you even if you are not suing them.

It's time to move back to jQuery and Prototype.js. Let's wait 20-30 years until these patents expire so everyone finally can use these nice state-management things.
