Diversity
Our people are our most significant strength and we firmly believe that fostering an inclusive work environment, with equal opportunities, is key to our ongoing success. We aim to maximise the potential of every member of the team, promoting mutual respect and ensuring that they are seen as an individual first and foremost. They are supported and empowered to achieve, regardless of gender, ethnic origin, nationality, marital or civil partner status, sexual orientation, religion or belief, age, disability or socio-economic background. The gender ratio across the firm as a whole is approximately equal. The Partnership is also diverse, in terms of gender, sexual orientation and ethnicity. Our staff are invited to participate in a Diversity Survey on an anonymous and voluntary basis. The data, based only on those individuals who completed the survey, can be found here. We are proud to support IP Inclusive, which is dedicated to improving diversity in the IP professions. We also support ChIPs, a non-profit organisation that advances and connects women in technology, law and policy, with partners and associates being members of the ChIPs London Chapter Committee. This commitment to diversity and equality is central to our recruitment process: we recruit on merit.
CSR
The firm takes Corporate Social Responsibility seriously, working in partnership with Queens Park Community School and Careers Academies UK to provide mentoring to students aged 16 to 19 years. The firm provides pro bono legal advice to DACs (the Design and Artists Copyright Society – a leading UK copyright and collecting society for artists and visual creators). We work with the society by providing pro bono legal services to artists caught up in copyright and licensing disputes. At this year’s networking event we used The Clink Catering company which provides prisoners with training and experience in event catering to equip them with qualifications and skills for the future.
Charities
Whether it’s dressing up, baking cakes for Great Ormond Street, raffles, quizzing or putting our running shoes on, we’re always keen to get involved and raise money for charity. This year the members of the firm have been supporting “Cancer Research UK” as its chosen annual charity. We have also participated in a range of other fundraising events including, the Law Society Legal Walk, “wear pink day” for Breast Cancer Now, Royal Parks half marathon and the London Winter Run . Last year the firm raised over £16,000 for Together for Short Lives (the firm’s chosen charity for 2021). Most recently a team from PG took part in the Bacchus 10km run through a vineyard in fancy dress.
