EXPERTISE AND ARTIFICIAL INTELLIGENCE
Expertise, enhanced by artificial intelligence
All work carried out by GIG Inventions is supported by artificial intelligence tools, from documentary research to analysis and drafting.
This approach speeds up case handling, enables more sources to be explored, increases cross-checking and strengthens the accuracy and consistency of documents. It frees up time for strategic thinking and personalised support, while helping to keep costs under control.
David Grèzes directs the work, reviews the analyses and approves the deliverables. Artificial intelligence thus amplifies his expertise and experience in protecting your innovations.
How I work with AI
I define the objectives, strategy and questions to be addressed. I use two artificial intelligence assistants to prepare research, structure analyses, compare documents and draft texts. I compare their analyses to cross-check lines of reasoning and identify points requiring further examination.
The fully equipped scenario for the firm includes 15 professional tools and services for research, drafting, figures and document checks, and for preparing and following up deliverables and proceedings. I use some of the most advanced AI models, available through premium paid subscriptions, with their reasoning settings at the maximum.
As of 11 November 2026, the overall projected annual budget for this scenario covers all IT tools and services selected for professional services, including those using AI. It is approximately CHF 49,000, including provisions and excluding hardware.
I verify references and quotations against the original sources, check the technical and legal analysis and revise the texts before delivery. I retain decision-making authority over the strategy and personally approve the deliverables.
Professional ethics and professional secrecy
This organisation preserves my independence and professional responsibility, and the primacy of the client's interests, in accordance with the rules applicable to European patent attorneys. AI is used within this framework, with clear information provided to the client and respect for their instructions.
Data sharing for model training is disabled. Information entrusted to the tools is limited to what is necessary for the matter. Before transmitting confidential information, I check the processing conditions, access, retention and any transfers in light of professional secrecy and data protection requirements. Unnecessary identifying details are removed; where the required safeguards cannot be ensured, the information concerned is kept out of the tools.
The client's specific requirements concerning AI are agreed at the start of the engagement and recorded in the agreement or the special terms.
