Raymond Wagenknecht

Patent & Trademark Attorney


Over the last 15+ years I've helped numerous companies develop comprehensive patent and trademark portfolios. I've enjoyed watching my clients launch companies based on medical device, life science, mechanical and electrical patents that I've secured.  We've obtained over 250 patents. I've also helped with licensing patents and assisted with the acquisition of my clients.

But my practice isn't limited to patents.  For over 10 years I've been securing trademark protection for brands and have represented brand owners in trademark disputes.  

My philosophy has been to build close relationships with my clients and grow my practice to meet their needs, which is why I now have the most diverse practice of any intellectual property attorney I know.

Now, how can I help you? 

I can help obtain patents and trademarks. I can assist with due diligence, freedom to operate (FTO) analysis, trademark opposition proceedings, and any other IP-related needs.
