Technology Center 2100 handles computer architecture and software, with art unit groups focused on computer reliability and control systems, memory access, computer architecture, databases and file management, software development, artificial intelligence (AI), and graphical user interfaces.
Technology Center 3700 is somewhat of a “catch-all” technology center, handling technologies as diverse as medical instruments, shoes and apparel, machine and hand tools, thermal and combustion technology, and refrigeration.
Technology Center 1600 is the home for life science patent applications at the USPTO. This includes applications related to organic compounds, organic chemistry, molecular biology, immunology, fermentation, and plants.
Technology Center 2400 handles data processing and telecommunications technologies, including multiplex and VoIP, cable and television, recording and compression, cryptography and security, and computer networks.
On this year’s World IP Day, WIPO Director General Francis Gurry called for a surge in green tech patenting to fight climate change. His charge follows a report that patenting for green energy technologies has slowed.
