Hiring a patent attorney can cost anywhere from $250 to $500 dollars per hour. This is why often clients will only ask the attorneys to search if it is possible to patent the idea and see if the attorney has any advice. In addition to attorney fees, there are also several office fees to consider when adding up the cost of patents. There are several different filing fees you might come across when filing a patent. There is a basic application fee, fees for the USPTO, and time extension request fees. Each of these fees can cost varying amounts.
The basic application fee costs $130. Additionally, there is a charge for each page of your patent. In general, each page can cost anywhere from $100 to $125. The USPTO fee can range anywhere from $200 to $400. The time extension fee will vary based on how long the time extension is. A one-month extension costs $200 for a large patent and $100 for a small patent. A two-month extension fee costs $600 for a large and $300 for a small patent. A three-month extension costs $1,400 for a large patent and $700 for a small patent.
