If you are looking for experienced patent attorneys at a reputable firm you should anticipate hourly rates to be a minimum of $300 per hour in areas outside major metropolitan areas and somewhere between $400 to $700+ per hour in major metropolitan areas. You may also want to consider working with a patent agent. Although patent agents are not attorneys and do not have the same breadth of legal knowledge, there are certainly many competent patent agents and even those with 5+ years of experience generally charge $200 to $400 per hour.
