Intellectual Property and Patents

Gooch & Housego occupies a strong intellectual property (IP) position. We consider managing our IP maturely and intelligently as a fundamental business activity.

Our patents provide us great protective value, allow us to collect significant licenses, help us keep secure both our own business and that of our customers, and prevent our inventions from enabling our competitors.

G&H currently files and receives new patents at a rate between five and ten per year. We expect to keep that level constant. G&H has a proactive approach to creating new business focused inventions, a well-defined IP process for our invention disclosure and selection process, and significant incentive payments for our employee inventors.

We track of all our active patents and the portfolio of products to which they apply. The following is a list of patents that issued in the United States or the UK. No guarantee is made of completeness or that this list reflects the current status. For that, please consult the USPTO or the UKIPO sites.
