Pengweixi (Rose) Sun’s practice focuses on patent and trade secret litigation of consumer electronics, semiconductors, complex technology and pharmaceuticals in district courts and the International Trade Commission.
Rose has experience litigating patents from the investigatory, pre-suit phase, discovery, expert discovery phase up to trial and post-trial. Rose’s experience in technology ranges from complex server systems, semiconductors, electronic ticketing software/hardware, to shavers and pharmaceuticals. Rose has experience litigating small molecule drugs under the Hatch-Waxman framework and biologics under the BPCIA. Her wide range of technological experience and understanding allows her to simplify complex technology into digestible key components for judges and juries. Rose helped secure a General Exclusion Order for a small business client in front of the International Trade Commission, and was part of a team that secured a favorable settlement for Gilead in protecting their blockbuster HIV drugs Descovy, Odefsey and Vemlidy. The suit involved nine generic drug companies and 15 abbreviated drug applications and resulted in a favorable settlement barring generic entry for at least 10 years.
As part of a lean team, Rose helped secure a $17.3 million royalty for Continuous Composites, which is currently the largest award in the 3D printing industry.
In law school, Rose won the prestigious Anthony and Susan Taylor Written Advocacy Award for Best Brief, and a semifinalist in the Oral Advocacy portion of the Hale Moot Court competition. During law school, Rose also clerked at the Children’s Law Center of California, and advocated for abused and disenfranchised children in the Los Angeles county dependency court.
Her zealous pro bono work and advocacy continues beyond law school. Recently, Rose secured a crucial and timely win for the Asian American Legal Defense and Education Fund in convincing the Western District of Texas from enjoining the enforcement of unconstitutional provisions of the Texas Election Code in light of the 2022 Primary Elections.
