Jackson Walker Helps Cirrus Logic Catapult Into IPO’s “Patent 300”

October 1, 2020 | Client Results



Cirrus Logic, a leader in low-power, high-precision mixed-signal processing solutions, has been listed among the top 300 U.S.-issued patent assignees for 2019 by the Intellectual Property Owners Association (IPO). This is the first time the company was included in the annual list of innovators.

A Jackson Walker team led by Austin partner Brian K. Prewitt assisted in obtaining 127 of the Cirrus Logic team’s 163 patents issued in 2019.

“We’re honored for our modest part in helping Cirrus Logic achieve this magnificent milestone,” Brian said. “Cirrus Logic has an outstanding staff of brilliant innovators across the globe and a tremendous in-house legal team who deserve all the credit for their company’s growing patent portfolio.”

The Patent 300, produced by IPO in collaboration with Harrity Analytics, has been published for 37 consecutive years using data obtained from the U.S. Patent and Trademark Office. Cirrus Logic is among just 29 organizations making the list for the first time.

Headquartered in Austin, Cirrus Logic offers hardware and software solutions that create innovative user experiences for the world’s top mobile and consumer applications. The company has more than 3,450 issued and pending patents worldwide.
