Don’t be fooled by low flat fee offerings for filing a patent application. At Kaufhold & Dix Patent Law, you pay once throughout the entire patent application process from the time of filing until the resolution of your case (either an allowance or final rejection).
Read all of the associated costs of other flat fee firms and often you will find that you will be billed separately for different aspects including hundreds of dollars for patent drawings as well as several thousand dollars for required responses to office actions (rejections) from the patent office. Many times, the person offering the flat fee will not even mention what the exact charges are for the drawings and office action replies in advance. You might even be charged handling fees to simply forward issue fees to the Patent Office. In the end the total cost for legal fees can be at least $10,000 and will often be more than $12,000. We include all of our services in a complete service flat fee agreed upon before work starts, and there are no hidden costs.
Further, we highly advise against using services that provide low cost “assistance” where you are actually the one writing the application with presumed oversight by a third party not putting their contact information on your application filing. If they are not willing to tell the USPTO they represent you, then they are not standing behind their work. In 20+ years of assisting clients, we have seen filings that are fatally flawed costing the inventor not only time and money, but the loss of patent rights due to statutory time restrictions necause they relied upon an insufficient filing.
