The patent lawyers mad that impossible a long time ago. Given something you want to do, it is nearly impossible to search for a patent that does it in less time than it takes to implement it from scratch. Beyond that, if you actually do search patents you open yourself up to treble damages to every idiot with an obvious patent out there wanting to claim the rights to something that took you all of 30 seconds to think of and another 5 minutes to write the code. The current advice is to NEVER read patents.
Beyond that, even if you find a patent that does exactly what you want and saves you months of development, nothing at all prevents the patent holder from demanding more than you expect your project to bring in for the first 5 years. And then, even if you implement something else you will have painted a big target on your back that practically guarantees that you will be eaten alive by court costs before you can even make a dime on your own work.
So no. Until the USPTO and other offices rais the bar for patents a LOT, AND court costs are cut by a factor of a thousand or so, they will remain nothing but an impediment to progress.
