Thank you to Peter Emerson and Addy Bridger from Page Hargrave for a seminar that was full of discussion, questions, case studies, examples and process associated with Trade Mark and Design. The expertise and practical knowledge that was demonstrated by Peter and Addy was second to none... The factsheets on patents, design, Trade Mark, domain names along with the invention/design record sheet and the brands checklist are a brilliant resource.
