Hasina A. Ali, Ph.D.

Hasina Ali, Ph.D., is a patent agent in Sterne Kessler’s Electronics Practice Group. Hasina’s practice focuses on preparing and prosecuting patent applications at the United States Patent and Trademark Office (USPTO) and performing invalidity, infringement, and freedom-to-operate analyses. Her technical areas of expertise include semiconductor materials and devices, microelectronics fabrication techniques, optics, nanotechnology, polymeric materials, solid-state sensors, biosensors, and wireless communication. She has also been involved in all phases of multiple inter partes review proceedings at the Patent Trial and Appeal Board for both the patent owner and petitioner. Representative technologies include communications, semiconductor device and processing, hearing aids, and nanomaterials.

Prior to joining Sterne Kessler, Hasina was Faculty in the Electrical Engineering and Computer Science Department at the Catholic University of America, where she taught courses on solid-state devices and microelectronic circuits. She was also a Postdoctoral Research Associate at the University of Maryland. Her postdoctoral research focused on high-energy storage device and technology. She researched carbon nanotube films for the development of high-energy supercapacitors. Her work involved synthesizing porous anodic alumina templates, developing carbon nanotube films using the templates, and characterizing the nanotubes using structural and electrical characterization techniques.

Hasina received her M.S. and Ph.D. from the University of Maryland. Her doctoral research focused on nanotechnology, semiconductor nanomaterials, polymeric materials, and solid-state gas sensors. She developed highly responsive gas sensors using semiconductor nanostructures. She was directly involved with the synthesis and characterization of the nanostructures, design and fabrication of gas sensing devices using the nanostructures, and testing of the fabricated devices.
