What will it cost to work with a Patent Attorney?

Whether you’re a big company or an individual inventor (or somewhere in between), most clients want to know how much it’s going to cost to hire a patent attorney.

Many attorneys charge an hourly rate. Some patent attorneys charge $500 per hour or more. On the low end, even an hourly rate of $200 per hour can add up fast. And the worst part is that you don’t know how much you’ve spent until the bill arrives.

But what if you could get a flat fee quote for a project, before you hire a patent attorney?

You can.

Trenner Law Firm does everything on a per project, Flat Fee basis.

Imagine knowing what it will cost to hire a patent attorney up front, before you ask your patent attorney to do any work.

Not an estimate, but a Flat Fee. When the bill arrives, the total amount charged is exactly what you were told it would cost before getting started.

That’s how Trenner Law Firm’s Flat Fees work.

For example, you may want to file a provisional patent application to get patent pending status for your invention. You call Trenner Law Firm and we tell you what it will cost. A Flat Fee. Not an estimate. There are no hidden charges. Then if you decide to work with Trenner Law Firm, we prepare a provisional patent application for you to review. We revise based on your feedback. If you have any questions, we answer those for you. When you approve the final draft, we file the provisional patent application at the US Patent Office and provide you with electronic copies of the filing paperwork the very same day.

Then when the invoice comes, the total bill for the project is exactly what we told you it would cost.

How Can We Help?

Patent Search

A Patent Search (or "prior art" search) can help you determine whether someone else has already applied for a patent for the same or similar invention. While there are times when it is more important to file a patent application right away, it is generally a good idea to do a patent search at some point before applying for a regular patent application.

Provisional Patent Application

Need to file a patent application quickly and inexpensively? The provisional patent application is recognized by the US Patent Office and most foreign countries as a valid way to get "Patent Pending" status. After filing a provisional patent application, you will have up to one year to file a regular utility patent application.


Inventors often ask “when should I file a patent application for my invention?” or “can I wait to file a patent application for my invention?” The short answer is – as soon as possible. Waiting to file a patent application risks losing all rights to the invention.

  • I am the co-founder and vice president of technology at Vescent Photonics. We have been working with Trenner Law Firm for more than four years and could not be happier.

    Scott Davis Vice President of Technology at Vescent Photonics
  • Trenner Law Firm is your all-in-one stop for Trademarks, Copyrights, and any other intellectual property law questions. Mark Trenner is very professional, knowledgable, and prompt. We used Legal Zoom before we found out about Trenner Law Firm for two trademarks. They filed everything and then did not provide any support when one of the marks was rejected. Trenner Law Firm took over from there, and has since been able to get that mark registered and has helped us with three others. Mark is always available for any questions we have as well. I highly recommend Trenner Law Firm.

    Emma Horn
  • I have worked with Mark Trenner and the Trenner Law Firm on several patents for almost 15 years and over 3 companies, I have always been impressed by their professionalism, attention to detail and solid patent construction. They quickly absorb new technologies and concepts and then clearly represent them in their patent embodiments. Additionally, I like that they are up front about pricing and explain expectations during the patent process. I whole heartedly recommend them for your work and don't think you'll be disappointed.
