About:
I am an intellectual property lawyer with a strong background in trademark and patent prosecution. I have extensive experience handling trademark applications for major clients in the pharmaceutical and fashion industries, ensuring compliance with national and international regulations. My work includes advising on trademark applications, oppositions, cancellations, and inter partes cases before the Intellectual Property Office. In addition to trademarks, I manage chemical and mechanical patent applications, overseeing their filing, prosecution, and maintenance. With a BSc in Biology, I bring a scientific perspective to intellectual property management, particularly in biotechnology and pharmaceuticals. My meticulous attention to detail and deep understanding of IP law allow me to help clients protect their innovations effectively.
