I was approached by a software engineer who developed a new way to organize the storage of backup files. The main peculiarity of the solution is that its difference from the analogs (computer programs) is only in the applied mathematical method. In spite of the fact that the patenting of such solutions is connected with legislative restrictions, we have found a way to get a strong patent. We have successfully protected the invention in Russia, and also registered the international PCT application. I wish the client a successful commercialization of the invention.
