In addition, Medley assists clients in developing and managing their patent portfolios across different jurisdictions, including drafting and negotiating software licenses, asserting patent rights and drafting non-infringement and freedom to operate opinions. Medley also responds to allegations of patent infringement, counsels in product design to help clients avoid infringing patents held by others, and advises clients on national and international data privacy laws.

“We are proud and excited to join Calfee’s IP group, which has an impeccable reputation throughout the country. Our clients will continue to benefit from our knowledge and experience with respect to their businesses and technologies, while further benefiting from Calfee’s deep talent pool,” said Medley.

Behrens’ technical background enables him to counsel clients on various intellectual property matters, including providing advice on patentability, non-infringement and designing around others’ intellectual property. He is well-versed in patent procurement and strategic patent portfolio development in the electrical, mechanical, software, biomedical and business method technology fields.
