My Approach

Developing a patent portfolio is often the foundation for starting or growing your business, even when funds are limited. As a solo practitioner, I can provide knowledgeable patent services at reasonable rates at the earliest stages of your inventive and business development process. 

A Team Member in Your Corner

Whether a single patent or an extensive portfolio of worldwide filings, I can act as your virtual, in-house patent manager to make sure responses timely are filed, technically sound, and protection is maintained.  I keep in regular contact with inventors or company representative regardless of where geographically located. 

Legacy of Success

For over ten years, I have worked with clients as thy evolve from early startups to publicly traded companies.  I have successfully secured issued patents that cover biotech research tools, antiviral agents, novel cancer compounds. pest control methods,  air purification apparatuses, fuel additives , and biofilm disinfectants.
