Legal Know-How

We are a boutique firm with registered patent attorneys rated AV - Martindale Hubbell and "Best of" awards.


Technical Chops

Business Ownership

We understand where you're coming from: we've owned our own businesses from boot-strapped, angel-funded to the family business. And our firm has been around since 2001.



We use flat fees for patent and trademark applications so you'll know your legal costs in advance.


Get It Done

We look for ways to get it done right, from the start. We say “Yes, if,” instead of  “No, because…”
