Henok Shiferaw

Primary Patent Examiner

I graduated with a Bachelors Science in Manufacturing Engineering/System, a Masters in Computational Science and Engineering from North Carolina A&T State University in 2012 and PhD candidate in Computational Science and Engineering in North Carolina A&T State University. I now work at USPTO as a Primary Patent Examiner in Electrical and Computer Engineering to evaluate patent applications in the Network Printing, Scanning, Color, Halftone, Image Analysis, Data Compression, Data Analysis, Data Encryption, Barcode Symbology, FAX/PRINTER/SCANNER Technology and Display System arts for compliance with federal patent laws and regulations

This is what I am doing right now

I am always looking to learn new things. I am currently working on a few projects related to Image Processing and Machine Learning. At the same time I am actively on the lookout for new opportunities and challenges that come my way.

I am a strong advocate for open source and I am always interested in working on new projects with new people. Feel free to reach out if you have anything to talk about, you can reach me through Mail
