Tips and tricks

Denis Levchuk, RU, patent attorney:

"Very good, powerful product for the money."

Daniela Filová, CZ, PATLIB:

"Personally, I think the most important feature is that GPI is fully supported and developed by the EPO and is highly adapted to European SMEs' conditions (but not only). So for European users, GPI should be the first-choice product."

Loudovikos Van-Heurck, GR, Member state national office:

"GPI is a very useful search tool." 

Özgür Güvenenler, TR, PATLIB:

"I would like to say that GPI really meets my expectations in many ways. Thank you again. I use it every day for my daily work. I open it at 8 o'clock till five. Whenever I need it, your team help me. I always find the answer to my question."
