Representative Clients & Testimonials

"I needed help with editing the Specification portion of my non-provisional patent application and wanted an experienced patent attorney to write the Claims section for me.

Having filed the Provisional almost one year prior, I needed this work completed within a two-week time frame. Marc offered his services at a flat fee that we could afford, and then helped me with several other elements of filing my own application online.

I found him to be an excellent listener, patient with my inexperience, and he took the time to analyze my invention for writing claims that have the best chance of being accepted by the USPTO. I feel confident that Marc will walk this invention through to a successful patent."

"When the time came to seek professional counseling on patent and trademark laws, it was important for me to find a law firm that understands and can explain those often complex issues in simple terms, therefore making it easy and quick to resolve potential issues. I found such a firm when I hired Baumgartner Patent Law.
