My office is in the Silicon Valley – San Francisco Bay Area of Northern California (more specifically, my office is in Los Gatos, near Campbell, Cupertino, Saratoga, and San Jose). My clients come from throughout the US and Internationally (in particular Canada and China).

Please feel free to contact me by phone, Skype, or Zoom, as well as by email. I am always happy to talk to new potential clients and explain how the patent and trademark process works.

I can typically talk for a few minutes and answer some basic questions about the feasibility of your patent, trademark, or copyright project. We can then discuss further after this initial contact, as mutually desired. These initial discussions are typically free of charge.

As a former inventor and startup founder myself, I have been in your shoes. The patent and trademark process is complex and a bit intimidating. There are many tricky rules. I remember what it was like doing this for the first time. As a result, if you are interested, I will try to explain not only “how” but “why” these various rules exist.

I also understand that inventors and startups typically have to operate on a limited budget. So we can go over the various cost trade-offs. My practice is to work in a transparent manner that minimizes the chances of unexpected bills.

Once I understand your invention (for a patent), or your business objectives and proposed name or logo (for a trademark), I can then give you some options and relatively firm price quotes. So you will get a good understanding of the costs. The same applies to copyrights and legal research (such as IP litigation support).
