Team organisation

The firm is divided into departments (patent, trademark, design, legal, renewal and internet services). All departments, in synergy with the legal department, are structured as a heterogeneous group of attorneys and lawyers with decades of experience in the IP field. The patent department handles multi-disciplinary fields, including mechanics, medical devices, material science, biotechnology, chemistry, electrical equipment, electronics, semiconductors, computer software and hardware and telecoms. The team is highly knowledgeable and keeps abreast of local and European IP legislative developments.

Client-focused approach

Clients of all sizes and from all industries worldwide trust GLP to design strategies to defend their IP rights in the most complex cases. Our staff ensure that every client receives the best advice and are updated, based on the targets that have been discussed, shared and defined. In the IP field, clients can verify the quality of the consultancy that they have received only when involved in a lawsuit, which occurs in only 5% of cases. GLP acts as if this verification were applied in all cases. For this reason, it is committed to the highest quality, both in consultancy and drawing up patent documents and in filing trademarks and designs. Some of GLP’s patent texts have been recognised as examples of best practice in national and international publications.

Growth and development tool

GLP believes that intellectual property is a fundamental tool for the growth and development first of a company and second of a national economic system. For this reason, GLP has – for more than 50 years – written publications that are distributed free of charge. It also continues to organise and promote events, courses and seminars. The firm maintains a private, in-house library of over 8,000 volumes.

International organisations

The team is registered to practise before the European Patent Office (EPO), the European Union Intellectual Property Office (EUIPO), the World Intellectual Property Organisation, the Italian Patent and Trademark Office and the Republic of San Marino’s Patent and Trademark Office.
