Flat Fees

We offer low flat fees that a small business or independent inventor can afford.  Our fees are competitive with the best prices you will find. We guarantee it. Contact us to find out.


We also do not artificially limit the number of claims or the number of pages of specification that we will draft and file. 

Attorney - Client Representation

You should be working directly with a patent attorney to prepare and prosecute your patent application. Don't settle for limited e-mail consultations with a "practitioner".



Patent prosecution requires competent representation by an experienced patent attorney. We represent our clients and we fight for them.


We have 20+ years of experience in patent law. We handle everthing from filing and prosecuting your application to patent appeals, infringement, and litigation. 

There are many "registered practitioners" who do not have the experience to properly handle a patent application on their own. We are a full service patent law firm that can handle matters at the Patent Office and Patent Trial and Appeal Board up to the US Court of Appeals for the Federal Circuit.

Patent Prosecution Highlights

Anchor 1

We offer the high quality attorney-client representation before the US Patent and Trademark Office (USPTO) that you need. Patent Office proceedings are often adversarial and patent examiners generally assume that applicants are represented by a competent patent attorney. The USPTO recommends that patent applicants be represented by a patent attorney. It must be understood that a patent may be a valuable piece of intellectual property or it may be a worthless document depending on how it is drafted and prosecuted.  


Stonebridge IP provides highly quality patent application prosecution at low flat rate fees that a small business or independent inventor can afford.  You will be working directly with an experienced patent attorney in an attorney-client relationship, to prepare, file, and prosecute your patent application.  


Stonebridge IP is a full-service patent law firm. We have experience representing some of the largest corporations in the world. We will provide you with the benefit of that experience utilizing the same strategies that the large corporations use.
