According to the United States Patent and Trademark Office (USPTO), it takes about 22 months to get a patent approved after taking the steps to file one. At any given time, the USPTO has several thousand pending applications and only a few thousand examiners available to review them. As a result, the processing of a patent takes about two years. Your first response from the USPTO is called “Office Action.” Since you will have to respond to the action and the USPTO will have to respond to your response, you can safely estimate that it will take at least three years from the date of your initial application to receive your patent.
If you're wondering how long it takes to get a patent, there's a short answer and a long answer. The short answer for a design patent is between one and two years from the filing date. The short answer for a utility patent is between one and five years from the date of filing. But these answers won't give you the full story.
The average time it will take to obtain a patent is 22 to 30 months from the date you file your patent application. The current average time is 24 months. This time frame will vary depending on the type of patent you are applying for and the level of complexity of your patent.
