As patent attorneys, we have of course always known it, or at least suspected it, but now we have it from official sources: your chances of getting a granted patent increases if you use a patent attorney for drafting and prosecuting your application, instead of drafting and prosecuting it yourself. The Swedish Patent Office (PRV) has earlier advised applicants that , even if it is not necessary according to Swedish law to be represented by a patent attorney, it is wise to seek such professional assistance when drafting and filing a patent application. Recent statistics from the Swedish Patent Office shows that the grant rate for applications prosecuted by a patent attorney is almost three times higher than for applications filed by applicants without representation.
