Who We Are

About Us

PatHub is the global patent marketplace, connecting patent buyers, sellers, practitioners, and other service providers. Pathub was developed by Cascades Ventures, whose founder, Anthony O. Brown, has been a pioneer in the field of patent monetization for the past 20 years. PatHub is an essential tool for patent owners seeking to monetize their patents.

Our Story

Note From the Founders

Creating value from your patents may seem like an impossible task. Every year, thousands of patent owners contact us at Cascades Ventures seeking our help in monetizing their inventions. Many of these patent owners are independent inventors or small businesses, who have little or no experience in licensing or selling patents. We repeatedly hear the same stories about the challenges they face: they don’t know how to contact the right person at a big company or they get no response when they do make contact; they don’t know how to value their patents or what terms to offer or accept that would be fair to them; they don’t know how to prepare a presentation or how to market their patents. Or they simply don’t know where to begin.  We see a lot of promising patents and exciting stories, but we unfortunately cannot work with everyone. This inspired us to create PatHub.

Our main goal with PatHub is to give patent owners the tools and the platform so that they themselves can succesfully monetize their patents. For more than twenty years, we have been at the forefront of the patent industry. We built our experience into PatHub's Monetization Guide, which is available to all patent owners who list patents on the site. This guide provides unique insight and proprietary tools for each step of the process, from initially making contact with prospective buyers all the way to negotiating a transaction. At the same time, PatHub's online marketplace provides a user-friendly platform for patent owners, buyers, practitioners, and service providers to get connected.

We hope you will join us at PatHub.
