Patents

Nine distinct inventions, protected by twenty granted US patents — several inventions issued as a family of continuation patents, grouped together below. The work was done with co-inventors at IBM Research and the Egypt Nanotechnology Center, and later at Imam Abdulrahman Bin Faisal University. Each number links to its record on Google Patents.

All filings are in the United States. A search of Espacenet (the European Patent Office database) returns no European equivalents.
