Patent Drafting and Prosecution

Patent drafting, filing and prosecution is our bread and butter and every step of the process is directed towards achieving our client’s desired commercial result. 

CMS Patent attorneys understand client challenges and deliver 'opposition ready' patents

Many of our patent attorneys have worked in industry, giving us first-hand experience of the challenges faced by our clients. We plough our opposition and litigation experience back into our drafting and prosecution, to constantly learn and improve, to deliver ‘opposition ready’ patents.

We have the expertise necessary to build a strong and commercially relevant patent portfolio. 

Multi-language patent lawyers

In addition to English, members of our team are also fluent in other languages including French, German, Chinese and Korean.
