Applying for a patent might seem wonderfully easy at first sight. As soon as applicants have developed their invention, they approach the patent office all on their own, download all available documents and how-to?s, write their patent application and off they go. ?Why should I ask a patent attorney, who takes a lot of time and causes additional costs, to only do exactly the same thing ? sending a pile of paper to the patent office?? This is what many of them think.
