— Legal 500 2021

Advising across the IP lifecycle

Our advice extends across the lifecycle of portfolios including the acquisition, monetisation, and defence of clients’ patents and their interplay with standards.

We actively support clients in a range of licensing matters ranging from due diligence work on acquisitions and divestments through to performing pre-litigation and licensing patent claim analysis and assisting with validity challenges in licensing and litigation.

Range of services

Our services include investigating mappings of patent claims to standards and products; preparing corresponding claim charts; providing technical support in licensing discussions; advising on grading and taxonomy for classifying client’s patent portfolios; assisting with preparation and submission of declarations to SSOs; and preparing technical test methodology in evidence of use analysis.

About us

Our team has many years of experience working in-house and as external counsel to large multi-national organisations, patent pool companies, and patent licensing businesses.

We use Patently® to assist clients with understanding the landscape of patent information in specialised fields, and we have developed in-house tools for more in-depth analysis of standard-related information.
